Transmission shutters while driving at speed.

I purchased this vehicle from Ghent Chevrolet in Greeley Colorado, since I have owned the vehicle I have had several transmission problems which caused the vehicle to stick in fourth gear and I have also have issues with the transmission violently shifting into first gear to the point it feels like I’ve been rear ended. I have had to replace the entire wiring harness and the water pump module as well as the thermostat module and the louvres in the front of the vehicle. I have service records for the vehicle for all the repairs and that state the amount of repairs has far exceeded the value of the vehicle and I’m currently having transmission issues again. Please help me find some sort of resolution to this situation! I have already tried to use and was rejected from the Colorado lemon law

I had transmission serviced 9 months ago. Transmission has always shifted hard ( like it was going to shift up to next gear , but then downshift back ) Had serviced and a transmissiom check 5/21/26 and now saying I need it replaced. Truck has 106,000 miles. I’ve heard so many reports of Chevy Silverado transmission going out right after 100,000 miles. If it’s a common problem , I feel GM should recall and repair/replace.

I had been driving my truck for multiple days, after a knocking sound suddenly started from under the hood. It was evident at any speed that wasn't idle. There were no check engine lights displayed on the dash. The sound was annoying enough that I took it in. According to the dealer technician, the transmission pump "completely detached" and was "rolling around inside the transmission." They found metal fragments in the transmission fluid, and they declared the transmission a total loss. I have no idea how my truck was still driving, but if the transmission really had failed so catastrophically, I was driving a ticking time bomb. What if it decided to completely give out while driving my kids to school as soon as I made a left turn across traffic?

I was driving on I-35 in Norman, Oklahoma, shortly after 7 am, when my 2020 Chevy Trail Boss with the 6.2 engine stopped running. I was in moderate traffic and shifted the gear shifter to neutral, and the motor would not restart, leaving me in traffic. I was able to slowly get on teh shoulder to avoid a collision, and the engine would not restart. I had teh vehicle towed to Ammco in Norman, Oklahoma, where it was determined that a catastrophic engine failure occurred. This is teh same problems that are associated with recalls on the 2021 and up 6.2 GM engine. luckly i was able to get to a safe place and avoid a collision.

The defective manufacturer lifters on my 2020 Chevrolet Silverado 1500 went on my truck damaging the lifters, camshaft, oil pump and I'm sure more than that. I know it's an ongoing investigation/lawsuit with General Motors, but they need to held accountable and should fix this issue free of charge. Not everyone has $5k-$10k+ to repair their engine due to their negligence. Thank you

I am writing to formally report a persistent and dangerous manufacturing defect regarding the rear window and seating assemblies in my 2020 Chevrolet Silverado. I have already had GM replace the rear window in 2023, it needs replaced again now in 2026. The rear window seal is failing, allowing a significant amount of rainwater to leak into the cab. Because of this ongoing water intrusion, the structural base and brackets of the rear seats have developed severe rust. Furthermore, I am deeply concerned that this constant moisture saturation is creating an unseen mold hazard within the cabin, which poses a direct health and respiratory risk to my passengers.This leak also risks damaging sensitive electrical components and wiring harnesses located under the rear seats and trim panels, potentially causing short circuits and sudden failures of critical safety systems while driving.Many other owners of this generation Silverado have reported identical issues, including cracked plastic frames around the sliding rear glass that cause the leaks. Because this defect compromises vehicle integrity, creates a risk of electrical failure, and poses health hazards from mold, I am requesting that the NHTSA investigate this issue as a potential safety defect requiring a manufacturer recall.

Sliding rear window leaking, causing mold and ruined seats. Had it "fixed" in 2023 only 3 years of owing it. Now here 3 years later the same issue is occurring and they're not willing to make it right. Mold causes a safety hazard for my children and anyone in my vehicle. My truck only has 30,000 miles on it and I shouldn't be having this issue

While returning from a camping trip my engine lost power. luckily I was close to an exit and managed to get it off the expressway and to a parking lot. I was able to leave the camper in the lot and have the truck towed to a dealer 30 miles away. I was informed by the dealer that the engine had sustained major berring failure. I was over 500 miles from home and I had 2 options, wait 2 weeks for a new engine to be installed or trade it in for a new truck. I opted for the trade in because I didn't want to wait 2 weeks. I figure I lost $7000 in trade in value and had to spend $2000 to have my new truck fitted for a 5th wheel hitch.

The vehicle was towed to a independent mechanic where it was diagnosed that the engine had locked up. The vehicle was not repaired. The vehicle then towed to a dealer where it was diagnosed that there was an engine, cam shaft, and barring failure related to Manufacture Recall Number : N252494000, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 50,000.

Chevrolet dealership diagnosed my truck and said the coolant control valve would have to be replaced.

The contact owns a 2020 Chevrolet Silverado1500. The contact stated that while operating the vehicle, four different warning lights illuminated: ABS, Service Brake Assist, Service ESC, and two specific "Brake System Failure" messages limiting the top speed to 42 MPH and 62 MPH, suddenly the vehicle went into limp mode and had to be towed. The vehicle will be taken to a dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 114,264.

My son was driving his 2020 Silverado Trail Boss (50,000 miles) when suddenly the brakes were inoperative. He had to drive around several cars to avoid collision finally swerving into the parking lane and using the gearshift lever moving the transmission into park to stop forward movement. He had no warning lights or any indication the brakes were going to fail. The truck was towed to Harbor Chevrolet on Long Beach, Ca. They diagnosed the problem as a “software update” and this was “rare”. They seemed along with GM customer service seemed not to be very concerned about the problem and just gave me some GM Reward points. We are afraid to drive the car at this point.

Odometer Fraud. The contact purchased a 2020 Chevrolet Silverado. The VIN plate was missing from the original location. The contact was able to locate a small VIN plate on the inside of the door. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 88,000, and at the time of obtaining a Carfax report, it was discovered that the mileage was 137,164. The contact called the Texas Department of Motor Vehicles.

This was a 6.2L V8 that is actively under investigation and recall for model years 2021-2024. it is a part of the same GM generation of engines 4th Generation, GMT T1XX. I was not told about the active recall for other members of the generation by the dealership in which i purchased it at in august of 2025. I purchased this vehicle less than a year ago and the engine has now suffered a catastrophic failure consistent with known 6.2L issues.

-My 2020 Trail-boss 6.2 Engine broke and stopped producing power and shut off, it is available for inspection and has been inspected by my local Chevy Dealer Tom Gibbs Chevrolet. -My son was crossing a railroad track and it shut off as he topped the tracks it shutoff at the tracks and he was able to coast down out of the way. If it shut off a second earlier he would have been stuck on the tracks and there is a list of what if's. My grandson in the car seat, my son gets out breaks his ankle and can't get my grandson out there is so many things that could have happened. -The dealer stated the 6.2 engine is known to have mechanical failures -The local dealer stated valve cover was removed and no movement in valve train needs new engine at a cost of $21,343.24 They realized that the original $250 rubber serpentine belt outlasted the engine with 123K miles on it -No warning lights, no rough running, no sounds just shut off no power.

Problem#1 :The transmission shits erratically and down shifts really hard and has a vibration going down the highway. Problem #2: The rear-end differential seems to lock up when turning sharp corners.

Was driving vehicle and it revved very high and then got stuck in a single gear. MPG have also been impacted as of late. GM saying VIN isnt under the valve body recall, but dealer has determined the valve body needs to be replaced.

* same part gone bad as other recalled vehicles. "Coolant control flow valve bad". Engine fan is staying on high blast, message displaying " engine power is reduced" truck will not drive at full power because the truck thinks its overheating because of bad part. If i remember correctly, it is code p1098. Bad part is intermittent. It Will happen randomly driving down the road. It comes and goes. I believe this is a safety factor . There is a special warranty or recall regarding this part with my year truck, but not my vin? Why not? Same part going bad with same codes and same problem ? Please consider looking into this concern and expanding the recall or concern for this reduced engine power safety concern. Thank you for looking into this.

I am reporting a failure involving a 2020 vehicle equipped with a GM 6.2L V8 engine that developed a cylinder 8 misfire along with diagnostic trouble codes P0300, P0500, and P0521. Dealer inspection revealed a severely scored camshaft and metal debris present in the engine oil, indicating significant internal engine damage. The failure appears to be related to a lifter or valvetrain malfunction, leading to improper valve operation and engine misfire. This issue occurred unexpectedly and creates a serious safety concern due to the risk of sudden engine failure during operation. This may be associated with known problems affecting this engine type and should be investigated further.

While driving in early morning while still dark outside, loud noise occurred with decreased acceleration on interstate. This placed my life and the lives of others at risk due to not being able to accelerate out of traffic coming behind me. Vehicle Taken to chevy dealership who advised lifter had broke and damaged camshaft. This occurred out of nowhere without any warning or lights on dash

I was driving at approximately 75 to 80MPH on the highway when my engine shutoff and the vehicle died while driving it. I was able to coast to the side of the road but had to cross two lanes to the left to do so while weaving in traffic to get to the shoulder of the road. There was no warning of any kind that would have made me aware of an issue prior to this happening. I was unable to get the vehicle started again and had to have it towed to my local dealership Hendricks Chevrolet in Columbia, SC. That occured on Saturday March 14th 2026, that Monday, I have had all regular and scheduled maintenance done to my vehicle either on time or prior to the recommended time including oil changes and the like. I went to the dealership and they told me that the engine had seized up and that this was a very well documented and common issue with the 6.2L L87 V8 Engine dating back to 2019 but that GM had only issued recalls on the 2021 - 2024 years to correct the issue. I asked the Service manager at Hendricks Chevrolet to file for a Goodwill Coverage request on my behalf to cover the repairs of the engine and he refused and stated that I had to do so through GM customer service line. I have done so since and my case number with GM is 92108267. My vehicle is currently at the dealership awaiting the go ahead from GM to replace the engine. I have an extended warranty on my vehicle that goes to 120,000 miles and the issue occured at 114,113 miles. This is a very well documented case where the engine connecting rod bearings fail due to oil starvation that leads to engine seizure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that the tailgate failed to lock manually, with the key fob, or automatically. While approaching the vehicle in the morning, the contact became aware that the tailgate had opened unintendedly. The vehicle was not taken to the dealer to be diagnosed or repaired.

The failure mileage was approximately 56,235.

Started to work first thing in the morning, the truck felt sluggish-like a lack of power. I drove about a mile to turn around and head back home, something was obviously wrong. When I got out of the truck there was a smell like something was hot and the wheels were extremely hot. I realized the lack of power was due to the brakes being locked. The parking brake was not engaged. After calling the local dealer for an appointment, I had to get the truck towed. Now the 2nd day at the dealer with no diagnosis, no service codes. The truck has approximately 77,000 miles with the original brakes from the factory and have never had to be replaced. The vehicle data display shows 42% of brake wear remaining.

Unexplained complete engine failure. Engine seized, no warnings, on gauges or lights. Dealership repair shop indicates engine has seized up.

The engine started making a lot of knocking sounds and it has no oil pressure now. The shop says the engine needs to be replaced.

Well taken care of 2020 trailboss upper control arm completely failed driving down the interstate with family in the truck. Suspect defect from ball joints. Only 68k miles. No warnings. Tire fell into suspension causing thousands in damage. Had to be towed. At high speed we could've all been killed. Seen multiple reports online of similar ball joint/ control arm failures. This needs to be addressed ASAP! Very dangerous.

Intermittent issue where info says brake failure/steering assist not working/limited speed to 43 mph. Very dangerous if you’re on the interstate. Becomes hard to steer, brakes don’t work, brakes start burning up. Have to carry tools with me to reset ecm. Very common problem with Silverado with 5.3 gas engine. Chevy needs to fix this issue before someone gets killed. I would give them my truck back if I could.

6.2L ENGINE NOISE AT START UP AND STAYS ON AND LOSES ENGINE POWER SLUGGISH ALL OF A SUDDEN WHILE DRIVING SAME ISSUE LIKE THE CURRENT RECALL ON ALL 6.2L EXCEPT MINE WAS BUILT RIGHT BEFORE APPROVED RECALL DATES BUT HAS SAME ENGINE L87 WITH SAME ISSUE AND IS CURRENTLY UNDRIVEABLE AND DANGEROUS IF TAKEN ON ROAD. REGULAR OIL CHANGES AT 50% OIL LIFE WITH RECOMMENDED MOBIL1 OIL & ACDELCO OIL FILTER.

I replaced the fluid in my truck at 142k miles and when I went through all of the gears and checked for drips or leaking it was fine on that front and then I went to reverse and all of the gears were neural and only revved and when I went into neutral it started driving forward like it was the drive gear.

I have 2020 Chevy 1500 with L87 engines on it. We have the exact same issues that the 2021 1500 recall is having. Loses power, noisy engine when at start. Paradise Chevrolet in Temecula told me that they were going to replace the engine per GM but then GM only auth the repair. 8 barring kits, 8 rings 8 piston kits lot of bolts and gastkit and seals. Talked to GM every tho it’s the same engine they won’t replace it since not on recall. Don’t understand how the same engine in a car one year before the recall. I have all the paperwork video of the noise pictures of the Pistons. I failed from the dealer. Had to get the truck towed to the dealer cause the car wouldn’t turn on and all this happened with only 68,833 miles.

Brakes applied on their own while driving. Before being able to stop the rotors both front and rear were very hot and the smell of burning brake pads was evident. Let the truck shit after getting off the side of the road for a bit. Brakes seemed to release started driving and the brakes applied themselves again. We slowly stop and go drove home a few miles on the side of the road with the flashers on.

Internal oil consumption. With no oil puddled or spattered under the vehicle at time of purchase from a dealership or since then, a dealer certified vehicle with AFM at 153 miles from leaving the dealer the oil was non-existant on the dipstick. This directly indicates a TSB, Techical Service Bulletin involving the cause of failed lifters causing internal oil consumption and damage to lifters, cam shaft, push rods, rings and possibly more. This is a common result of the Active Fuel Management system which shuts off some of the cylinders for fuel economy for Chevrolet V6 and V8 engines. The problem was reported to the dealer by me imediately after the oil check at 153 miles and then towed to the dealer. As this is considered a catastrophic amount of oil loss, the vehicle could've been rendered inoperatable during operation in traffic and been a servere safty hazard. The dealer after initial inspection sent me a message that they think the problem is an undetectable small leak so they put some dye in the oil to check it. Which evades the actual internal consumption problem of 1.5 to 2 or more quarts of oil lost in just 153 miles by that ratio that would amount to 13 quarts per 1,000 miles. And helps them stall for time, to try to run out the very short 3 month/3000 mile drivetrain warranty. There was noticable erratic engine performance and some shudder but that shudder may have come from the transmission. The odometer read was 115690 at purchase and 115843 when towed=153 miles driven from when the certified inspection was performed for a loss of 1.5 to 2 quarts that I know of, it could have been much more oil missing. A suddenly inoperatable vehicle in town at intersections or on the highway at high speeds could be deadly for myself or others in traffic. I took and have videos of checking the dipstick to show it dry but it's an mp4 file which I don't see a place to upload it here. Available upon request.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving approximately 5 MPH and exiting a parking lot, the rear wheels locked up as if the brake pedal was depressed. There was no warning light illuminated. The vehicle was stopped and shifted to park(P), and the vehicle was turned off and restarted several times to reset the vehicle; however, the rear wheels were still locked up. The contact disconnected the battery cables and was able to unlock the rear wheels. The contact stated that the failure was intermittent, but was a recurring failure. The contact had taken the vehicle to a local dealer, where it was not diagnosed, and the vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 26V083000 (Power Train); however, the VIN was not included in the recall. The manufacturer was not informed of the failure. The failure mileage was approximately 92,000.

The first thing was the whole engine shut itself off going 40mph and slowing down thankfully after I turned the truck off and back on it started right back up then I was driving 75 on the highway a couple days later and the whole truck started to shake as check engine lights came on and flash and the engine started to tick and groan. We pulled the spark plugs and cylinder 5 had clearly not been firing as it was designed to and then later found that the entirety of cylinder 5 had basically shredded itself from the inside out. Now my truck is waiting at the shop for a new engine. Both cases I had my kids in the car trying to get home.

My entire engine and the right bank lifters failed. Thankfully, these issues didn't fail until my truck was parked in my garage. No warning lamps did not trigger until these issues started. There was no warning. I have been having engine issues with this truck dating back to 2022. I will include all documents showing the issues I've had in the past 3 years. I was informed by the dealer that this is a known issue with this year and model of truck and even they were surprised that GM hasn't issued a recall. The vehicle has been inspected by the dealership only.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving approximately 45 MPH, the vehicle was shuddering with an abnormal sound coming from the rear of the vehicle. There was no warning light illuminated. The contact stated that the failure only occurred at speeds over 40 MPH. The vehicle was taken to an independent mechanic, who diagnosed the vehicle and determined that the transmission control valve had failed and needed to be replaced. The vehicle was not repaired. The contact researched online and associated the failure with NHTSA Campaign Number: 26V083000 (Power Train); however, the VIN was not included in the recall. The manufacturer was not informed of the failure. The failure mileage was approximately 80,000.

During an extreme cold event in Interior Alaska (–44°F), the vehicle experienced a sudden emissions‑system failure that triggered an EPA‑mandated Limp Mode, limiting the vehicle to 5 MPH on high‑speed highways. This created an immediate life‑safety hazard because it was impossible to maintain a safe speed or exit the roadway due to snow berms. Prior to the failure, the vehicle displayed “Service Emission System” warnings and multiple DTCs related to the reductant heaters and sensors. A dealership technician later confirmed a “burnt pin” at the reductant pump connector, consistent with thermal‑electrical overload. This failure mode matches GM’s TSB 21‑NA‑006, describing connector overheating in cold climates. After the repair, the vehicle continued to exhibit safety‑critical symptoms, including harsh downshifts, delayed engagement, and jerking during deceleration, consistent with Recall 26V083000 (rear‑wheel lock‑up risk). The vehicle also continues to emit an electrical burning odor in cold temperatures, consistent with Recall N192206310 (block‑heater fire risk). The only GM dealership in the region issued a “Termination of Business Relationship,” preventing access to all recall and warranty repairs. This has created a 321‑mile “Service Desert,” making it impossible to obtain federally mandated recall remedies. The vehicle remains unsafe to operate due to unresolved transmission, electrical, and propulsion issues.

Brakes lock up on vehicle while driving Must turn vehicle off and restart several times to disengage brakes. This has happened twice in the last 8 weeks, very concerning as we cannot use our travel trailer as we do not trust this not reoccurring. Chevy dealership says there is a recall on this issue but not on my truck?. But they say it is THAT problem

Rear wheel lock at speed up due to failed valve body and transmission

In several situations, I have lost partial or complete power steering ability. Once, while driving, I recieved a SERVICE ESC message and steering became quite difficult. Another time, power steering was completely gone, making steering impossible, although every other aspect of the vehicle operated normally. In both instances, there was no clear issue and after some time with the vehicle parked and off, it would return to normal. Possible loss of power steering unexpectedly is a serious concern at this point.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, and the rear wheels locked up. The contact stated that the failure almost caused a crash. No warning lights were illuminated. The rear wheels locked up for several seconds, then the rear wheels released, and the tires chirped. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact referenced an unknown recall with a similar failure description; however, the VIN was not under recall. The contact stated that the vehicle was important due to scheduled doctor's appointments. The manufacturer was not made aware of the failure. The failure mileage was approximately 73,000.

Lifter failure in 2020 Silverado 5.3 engine causing loss of power while driving.

Engine failed on interstate while pulling my RV. Almost had a bad wreck due to this happening. This is the known 6.2L engine failure issues. Had to have motor replaced by Chevrolet and had to pay out of my own pocket.

We own a 2020 Silverado with a 6.2L L87 engine… I am aware of open investigation # EA25007… Our vehicle had sudden engine failure.. no prior warning lamps before failure. (Our vehicle had no open recalls) Once vehicle engine failed left us with no power… had to coast vehicle to a stop. Will not restart. Verified proper oil level on dipstick so vehicle was not low on oil. Had to tow vehicle to shop .. retrieved code P0016 - crankshaft position Oil pan was removed and found bearing material as mentioned by GM issued recall 25V-274. Verified oil pickup tube was not clogged. All symptoms explained by 25V-274, we’ve experienced.

On September 27, 2025 while driving to my nieces soccer game my 2020 Silverado Traill Boss LT started losing power while driving. I was at a Red light when I felt the truck not properly responding to me pushing the gas pedal once it turned green. It slowly started accelerating and then with all the lights still illuminated on the dash, the truck completely stopped working with No response to the gas pedal. I had to let the truck coast forward while driving through an intersection. Thank God there was not that much traffic behind me and any cross traffic. I managed to pull the truck over stuck on the side of the road. My wife had to get a ride from a family member to reach the destination while I had to call a tow truck and have it towed home. Ironically, I believe the truck had just got out of Warranty, what a complete waste of thousands of dollars including the warranty that is always useless. I did not reach out to the dealership because I knew it was going to cost me an arm and a leg just for a diagnostic only for them not to find a problem. There was No Warning Light Flashing to notify me that my truck was taking a dump or any error code of any sort for a diagnostic to pinpoint the issue. I am surprised this has not turned into a Class Action Lawsuit (not yet anyways). My Father made me a Chevrolet person but with all the recent Engine/Powertrain problems with General Motors. I always believed the slogan "The longest lasting dependable trucks on the road". Tanks to YouTuber "@Donslife" for keeping the Public informed of all the latest updates with all these issues. This might be my last Chevrolet ever unless they could fix these issues and take some type of customer reimbursement/assurance/future or current incentives.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that immediately after leaving the dealer after the vehicle was purchased, the check engine warning light illuminated. Several days later, there was a loud knocking sound coming from the engine before the engine failed. The contact referenced NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The vehicle was taken to a dealer and an independent mechanic, but was not repaired. The vehicle had experienced catastrophic engine failure. The check engine warning light was displayed, and audible knocking was coming from the engine. The manufacturer was notified of the failure. The failure mileage was 153,000.

The vehicle experienced a transmission control malfunction related to a transmission solenoid (diagnostic code P0776). The transmission exhibited abnormal shifting behavior and drivability issues, prompting a warning indicator and dealer inspection. The condition affects the powertrain and could impair safe operation of the vehicle, particularly if shifting becomes unpredictable or the transmission enters a reduced-function mode while driving. The issue was confirmed by an authorized Chevrolet dealership, and the vehicle was subsequently deemed inoperable pending replacement of the required transmission solenoid component. The vehicle was inspected by General Motors on November 3, 2025, at which time GM confirmed that the required part was on national backorder with no immediate availability. The vehicle remains unavailable for use due solely to the lack of this GM-supplied component. A warning indicator and drivability symptoms were present prior to removal from service. The component is currently retained by the servicing dealer and is available for inspection upon request. General Motors has advised that this component is subject to a widespread national backorder affecting numerous vehicles, resulting in extended periods where affected vehicles cannot be repaired or safely returned to service.

To Whom It May Concern, I am writing to formally file a complaint regarding my 2020 Chevrolet Silverado 1500 Diesel and to request immediate review and assistance from General Motors. I purchased this vehicle from a GM dealership in 2024 with approximately 70,000 miles for roughly $42,000. The vehicle currently has approximately 121,000 miles. Since purchasing the vehicle, it has suffered major breakdowns approximately every three months, requiring repeated costly repairs and making the vehicle unreliable for regular use. Most notably, the vehicle experienced a full transmission failure at approximately 103,000 miles — just after the factory warranty expired, requiring complete transmission replacement at my expense. To date, I have spent nearly $20,000 in repairs, including but not limited to: •Full transmission replacement •Two alternator replacements •Glow plug system failure •Coolant control valve failure •Engine control / computer module failure •Transmission cooling system failures •Ongoing electrical system issues •Additional drivetrain and mechanical problems These are critical powertrain, electrical, and engine management components — not routine maintenance items. The repeated failure of such systems strongly suggests underlying manufacturing or design defects. The vehicle has been properly maintained and serviced, yet continues to experience serious and recurring defects well beyond what would be considered normal wear and tear for a modern diesel truck. At this point, my total investment in this vehicle exceeds $62,000, and I am left with a truck that I cannot trust and that has become financially unsustainable to own.

Transmission/ torque converter. Truck feels like you are riding over rumble strips and shaking steering wheel. Confirmed by dealer. No warning signs

At highway interstate travel speeds, vehicle was losing intermittent power. Exhaust at stopped, idle during trip smelled heavily of gasoline. White smoke blowing from exhaust with only 38k miles on the truck. Dealership is replacing the entire engine now and sounds like GM doesn’t want them to fully explore the cause of failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 75 MPH, the vehicle lost motive power with a tapping sound coming from the front passenger’s side of the vehicle. The message "Monitor Brake Service System" was displayed. The vehicle was pulled over to the side of the road and inspected, but no failure was found. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the lifters and camshaft needed to be replaced. The vehicle was not repaired. The vehicle was taken to a different independent mechanic, where it was diagnosed and determined that the lifters and camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 160,000.

INTERMITTENTED,NOT ALL THE TIME BUT I GET A HESITATION WHEN I PUT THE TRAN IN DRIVE PRESS THE ACCERATOR THEN IT LURCH FORWARD UNEXPECTED......

The contact owns a 2020 Chevrolet Silverado 1500. While driving at an undisclosed speed, the brakes failed to engage while the brake pedal was depressed. The message "Service Brake Assist" was displayed on the instrument panel. The contact researched and became aware of an unknown recall; however, the VIN was not under recall. The vehicle was taken to a dealer where it was diagnosed and determined that the brake master cylinder was leaking and needed to be replaced. The vehicle was repaired; however, the message "Service Brake Assist" was displayed on the instrument panel again. The manufacturer was notified of the failure. The failure mileage was approximately 101,593.

Vehicle was brought to Payne Chevrolet(Weslaco,Tx)for Recall N242454440. After the software update, the vehicle entered 'Limp Mode' and threw a Permanent Fault Code P2817 (Solenoid 8 Stuck Off). The dealership and GM Executive Resolution (Case #86918646) have confirmed this is a mechanical failure of the valve body, but are refusing/delaying the remedy due to a branded title. The vehicle is currently grounded and unsafe to drive as it risks rear-wheel lockup. GM has failed to provide a timely remedy or alternative safe transportation.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving approximately 40 MPH, the contact stopped for a traffic signal, and the accelerator pedal was depressed when the light changed; however, the vehicle failed to respond. The contact stated that the engine was still running; however, the vehicle failed to respond while the accelerator pedal was depressed or the gear shift lever was moved. The contact stated that the check engine warning light was illuminated. The vehicle was towed to a local dealer, where it was diagnosed, and determined that the Transmission Control Module needed to be re-flashed. The vehicle was repaired; however, the failure reoccurred. The contact had taken the vehicle back to the same dealer two more times for the same failure, however the vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 41,000.

The Timing Chain failed. It is at the Dealership available for inspection. Vehicle was unable to accelerate correctly while driving. If it had blown a valve or locked up the engine we would have been stuck on the highway with my kids in the vehicle. Problem has been confirmed with the dealer. It is a known defect with this vehicle but my VIN was not one that was recalled. No issues had came up before it failed. Just went to accelerate and you could feel it slipping and the truck stuttering forward.

I pulled up to a traffic light at a busy intersection in Lubbock, TX, and the engine just shut down on approach to a red light. The vehicle still had power (radio, headlights, AC/heater, etc.) but the engine would not start or even turn over and try to start. The vehicle was towed to a Chevy dealership in Lubbock, TX, and they said they believed it was an internal engine failure but wouldn’t be able to look at it for several weeks. I had it transported to my hometown in Taylor, TX, and my certified mechanic replaced the starter and battery solenoid but the engine still wouldn’t start. They drained the oil and found metal shavings in the oil. They too believe that the engine suffered a catastrophic failure and needs to be replaced.

While driving home from work the truck displayed numerous trouble codes including ebc failure, braking failure, traction control failure and trailer brake failure as well as vehicle governed to 42 mph. I took it to the dealership and they checked all of the braking system and could not find any issues. They reset the codes, and changed all 4 pads and rotors as all 4 wheels were 1/32 out of true as a precaution. I drove it home about 5 miles with no issues. The next morning I was on my way to work and the codes reappeared with me being governed to 62 mph. At the stop sign I had no braking at all. Pumping the brakes resulted in no braking or pressure in the pedal. Luckily there was no traffic and I was able to use a hill to stop. I turned around and went the mile back to my house and was unable to stop again ending up with the front end in my neighbors yard. I had the vehicle towed back to the dealership where they still have not found a cause or a solution to the issue

The contact owns a 2020 Chevrolet Silverado. The contact stated that while the vehicle was parked, turned off, and unoccupied, the rear of the vehicle caught fire. The fire was initially extinguished by a maintenance worker, and the fire department later applied water to the area to prevent the fire from reigniting. The fire department was unable to determine the cause of the fire, and a fire report was not provided. The contact was unaware whether a police report was filed. The vehicle was not destroyed or towed. The vehicle was taken to a dealer, where it was diagnosed that the rear wiring harness had failed and needed to be replaced. The dealer also informed the contact that the rear bumper and tailgate were damaged as a result of the failure and would need to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was not available.

Rear wheel lockup due to transmission valve body issues.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle unexpectedly sputtered. There were no warning lights illuminated. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for further assistance. The approximate failure mileage was 73,000.

The component that failed was the wiring harness installed in the engine area. the harness was installed right next to a dip stick. The dip stick has a sharp metal piece welded to it and it punctured the harness cutting wires on the inside. This could have been a potential fire hazard. The problem was able to be reproduced, inspected and confirmed by a certified chevy mechanic at Philips Chevy in Frankfort, IL. The mechanic also showed me the failure point on the vehicle upon a visit. The dashboard lights were flashing randomly, headlights were very dim which it very difficult to see, android auto stopped working and not able to use hands free, so that became a safety issue, cruise control stopped working, and was receiving errors for a failed fuel pump.

The contact owns a 2020 Chevrolet Silverado 1500. While operating in negative (-41°F) degree winter conditions, the "Service Emission System" entered an EPA-mandated speed limitation in LIMP Mode messages were displayed. Dealer diagnostics confirmed DTC: P20B9 (Heater Control Circuit Open) and P20C1. The failure was identified as the melting of the Diesel Exhaust Fluid (DEF) tank electrical connector due to undersized terminal pins overheating (Joule heating). The contact stated that it was a latent design defect that posed a fire risk and a safety hazard due to sudden loss of motive power in arctic climates (-45°F). General Motors acknowledged the defect in 2500HD models, Special Coverage: N212342980; but excluded the 1500 models. The failure mileage was 29,354.

What happened: In mid-December 2025, my 2020 Silverado 1500 (VIN: [XXX] ) suffered a catastrophic failure of the DEF Tank Assembly (P/N 84914535) at 29,354 miles—less than 30% of its warranted life. This is a latent design defect involving undersized terminal pins that suffer thermal degradation and melt the connector during high-amperage heater operation in arctic conditions (Ref: GM TSB 21-NA-006). Component Availability: The failed assembly is held at the dealership. I have submitted a "Part Preservation Request" to ensure it is available for forensic inspection by federal regulators. Safety Risk: The failure triggers an EPA-mandated "Limp Mode," initiating a software-forced reduction in speed. Unexpectedly losing speed on high-speed, icy Alaskan highways—where roadside snowbanks prevent safe egress—creates an extreme risk of rear-end collisions. Furthermore, a vehicle restricted to 5 MPH or rendered inoperable in temperatures of -30F to -50F poses a direct, life-threatening risk of cold-weather exposure in remote areas. Confirmation: Failure was confirmed by Lithia Chevrolet GMC of Fairbanks on Jan 7, 2026. GDS2 diagnostic verified DTCs P20B9, P20C1, P205D, and P204C. Data was reviewed by the GM District Manager of Aftersales (DMA) and GM Customer Assistance (Case #[XXX]). Warning Symptoms: Check Engine lamp and "Service Emission System" message appeared in mid-Dec 2025, followed by a "Speed Limited" countdown. The electrical disconnect was abrupt due to terminal pin melting, as documented in my forensic engineering report.

Transmission bucks and truck just stops for no reason.

I own a 2020 Chevy Silverado 1500, the truck currently has 51,400 miles on it. I started noticing a vibration while driving home from work that continued to get worse. After some quick online research I learned that the torque converter on the newer Chevy and GMC trucks is a weak point in their assembly. This is a very common issue and complaint for owners. The manufacturer has done nothing to resolve it or honor repairs on the defective product. My truck was one month out of the 5 year/60,000 mile warranty, they would not honor repairs because it was outside of the time window. The internal parts break up and destroy a transmission. Luckily i caught it early enough before it caused my transmission to fail while driving. I do not have the part with me. I took the truck to a shop for repairs and they did not return the defective part. No warning lights came on the dash.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while his son was driving 75 MPH, there was a knocking sound coming from the vehicle. The driver pulled over and turned the vehicle off, but the vehicle failed to restart. The check engine warning light was illuminated. Upon researching the failure, the contact associated the failure with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The vehicle was towed to the local dealer, where it was diagnosed and determined that the engine had seized. The vehicle was not repaired. The manufacturer was contacted and confirmed that there was no recall coverage on the VIN for the failure. The failure mileage was approximately 165,000.

6L80 transmission shift flared when shifting from 2nd to 3rd gear and shuddered when driving at 45 - 50 mph and about 1400 rpm’s. The Torque Converter Clutch was spasming out causing the the torque converter to shudder which caused the torque converter to overheat at 250 degrees therefore exploding the torque converter that shot metal inside of the transmission blowing it up.

Bad shuttering, slow acceleration, clunking noise, check engine light flashing all started while driving home. Took it to a transmission shop and they said it was the TC and transmission. I then called the dealership to see if there was a recall, and looked up any recalls. Since I have had fluid flushed and changed, and still have the problems. This has been an on going problem for a couple of years now. It was just out of warranty for dealership to fix. It started while I was on a highway and had very poor acceleration control.

The 6.2L engine failed. The same as the 2021-2024 recalls.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving approximately 65 MPH, the vehicle started to hesitate with several unknown warning lights illuminated. The contact stated that there was a misfire in the engine, and her husband pulled off the roadway and turned off the vehicle. The vehicle was restarted and driven back to the residence at speeds no greater than 50 MPH. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the left engine lifters had collapsed and needed to be replaced. The contact was advised by the dealer that the right-side engine lifters should be replaced while the engine was disassembled. The vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 96,000.

The truck had a lifter failure which caused the pushrod to bend damaging the camshaft as well. I spent $5000 dollars just for the problem to happen again. I’ve have spent nearly $10000 on this issue. This not something you expect from a truck that you pay nearly $60000 for.

Intermittent and sudden loss of power steering. The only message displayed briefly then went out was “service trailer brake controller”. Brought vehicle to Dealership. The grounding strap behind the front right wheel that goes to the frame (Earth Strap) was rotted. This seams to be a very common problem with this model truck and is dangerous.

Driving on highway truck lose power, engine lights start to flash and cracking noises start to come from engine. The lose of speed almos cause another vehicle to rear end me, Truck gave no signs or warnings before. Truck was delivered to a local shop and due abundant amount of metal flakes in oil engine need to be replaced

GM declared my original engine as unfixable and decided to replace my engine luckily with 2 weeks remaining in warranty. It had similar clicking noise to everything else I've seen related to this 6.2L having issues. It currently has a new engine that can be inspected if need be. As well as receipt given to me from Klein Chevy from engine replacement. My engine could've failed while driving if I didnt notice the clicking noise prior to getting it looked at. Putting other in danger if driving on a public roadway. Yes the noise/defect was reproducible upon dealer looking at it. Unsure if the vehicle was inspected by the actual manufacturer but they removed my motor and sent it back to the factory. Was never inspected by police or insurance that im aware of There was no check engine light or warning lamps, only thing I noticed was a clicking noise that the common layman would have probably missed, they appeared roughly around 46,000 miles.

Engine Failure 6 Nov 2025 Yes, engine is available for inspection. Possible loss power, unable to control the vehicle. Vehicle engine failure has been confirmed by dealership, Ruben Milton Chevrolet and Jim Hudson Cadillac in Augusta Georgia. Vehicle has not been inspection by manufacturer, police, insurance representatives. No warning light, no knocking noise, no messages on dashboard.

Back in 7/2025, I was going to a Dr appt in Chandler, Az. When I arrived in Maricopa, Az, my truck stalled at the first stop light and would not start. I went over Kraegan Auto parts and bought a battery. After about 10 days, I was having to jump start my truck for the next few days. I took the battery back and they realized that it wasn’t the battery my truck called for. So, now I have the correct battery and everything working like it supposed to. In Nov 2025, my battery was starting to drain like overnight, and jump starting my truck every morning. I also told them, that the transmission was acting up. When I got on the highway my truck would be at 5000 rpm while doing 60 mph. I be would have to pull over to side of the highway, shut the engine down, and restart. Usually it would be good after the first time. So, up until now, I have no heater, no AC, my windows don’t go up or down, cruise control don’t work, l can’t move my power seat, so my wife has to put a pillow behind her and a pillow beneath her when she drives our truck. And I be still haven’t mentioned all be the little icons that are lit on the steering column. My truck is at the Jerry Seiner Casa Grande, Az. I have the protection plus coverage on my truck with GA Security, and I was told that because it’s a battery issue and found me at fault, they won’t cover me and I need to pick up my truck, because I can’t afford a $680.00 price tag. I’m on Medicare. That’s why I paid the $3500 for the protection plus coverage. So I guess it’s my fault or fault of my battery, my transmission doesn’t shift gears, power windows don’t work, heater or AC don’t work, can’t forget the cruise control. They said they are not covering nothing, to come get my truck.

While driving at highway speeds, multiple warning lights illuminated on the dashboard at the same time, including engine and powertrain warnings. The vehicle suddenly began operating abnormally, with loss of power and unstable driving behavior, making it unsafe to continue driving. This same issue has occurred multiple times previously and the vehicle has been taken to an authorized Chevrolet dealership for repairs on three separate occasions. Each time, repairs were performed, but the problem returned. The most recent incident occurred while driving on the highway and created a serious safety risk to the driver and other vehicles. The vehicle is not safe to drive.

My 2020 Chevy Silverado needs a torque converter replacement. My truck is at 90k miles and out of drivetrain warranty. However, this is a known GM problem with trucks (and other vehicles in this class of engine/transmissions). I have talked to GM corporate and they are only willing to rebate 20% of the cost of this repair. I believe they should pay for the entire repair since this is a known problem for all these vehicles in this class. Please help me to get GM to understand this and fix this known problem.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while starting the vehicle, there was an abnormal odor coming from the vehicle. Upon inspecting the vehicle, the contact became aware of coolant leaking from the front of the vehicle near the transmission, with the check engine warning light illuminated. The contact retrieved DTC: P0016. The vehicle was taken to the dealer, where it was diagnosed, and determined that the coolant control valve, motor mount, and camshaft timing had failed. The dealer informed the contact that the coolant control valve, motor mount, and wiring harness needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for further assistance. The approximate failure mileage was 88,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that upon starting the vehicle, there was an abnormally loud engine camshaft bearing sound coming from the engine. The engine warning light was illuminated. The vehicle was taken to the local dealer, and after three days, it was determined that the camshaft bearing had failed, and the engine needed to be replaced. The vehicle was not repaired. The contact linked the failure with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling) and NHTSA Action Number: EA25007 (Engine and Engine and Engine Cooling). The manufacturer was contacted and opened a case. The failure mileage was approximately 45,000.

On Sunday Nov. 16th, my steering wheel felt like it was "slipping", akin to how it feels when your serpentine belt tensioner is failing. I checked it out while wife turned the wheel, didn't see any problem, and we went on our way. Later in the day as we were leaving a parking lot, the problem occurred again but worse. And we got a warning about trailer brake controller needs repair. After reviewing similar problems on Reddit, I found it was still safe to drive, so we drove home without further incident. Monday I decided to take it to O'Reilly auto parts and have a code scan done. Except, as soon as I turned out of the driveway, my wheel completely froze up solid. I could NOT move the wheel (q2)! Since the wheel was still turned, I backed it into the driveway and we took our car to buy our own code scanner. It showed more than just one fault code for the brakes, there were 5. I called Fox Chevrolet to schedule al appointment for the next day. Fortunately, the failure occurred as the Advisor attempted to turn the wheel (q3). Long story short: problem was a rusted/rotted out ground wire (q1)! Behind the front driver side tire, encased in a boot. Tech told the Advisor he'd never seen that one before. $40 part, and $400 to install it (q4). I was happy it wasn't a power steering rack failure (electric) but the more I thought about it, felt I needed to report this. You needed a dealer scanner to catch this and trace it to a ground fault. Probably better for you to contact dealer Advisor and Tech to get a better breakdown on this (q1). Dealer was great, they could have sold me an $1800 steering rack and I'd have never known. Could this failure have happened to someone driving on the street and this pop up all of a sudden (q2)? I believe so. Glad I didn't find out firsthand. The problem went away overnight twice, and then all of a sudden your wheel is LOCKED. I'm curious as to if others are or have faced this, thus my submittal. Thanks for your time.

Sudden intermittent loss of power steering, issue confirmed by Chevy Dealership. No warning lights were displayed.

Transmission, would lock up for no apparent reason . At random speeds, they continue as if nothing was wrong. Took to dealership, couldn't get to it for a week. End up at a transmission shop said it through some code. required rebuilding the transmission . 88,000 miles on truck. From time of first incident to first shop visit one week. Same transmission in similar trucks is under recall but this vin# is not.

THIS IS A RECALL REMEDY FAILURE REPORT UNDER 49 U.S.C. §30120. My 2020 Chevrolet Silverado 1500 (VIN: [XXX] ) received Recall 24V797000 on June 9, 2025. The ECM update is intended to detect incipient clutch-pressure or gear-ratio deviations—early signs of a developing slip—and automatically force limp mode to prevent rear-wheel lockup. On August 23, 2025, after the recall was performed, the truck experienced rear-wheel lockup at highway speed. Limp mode did not activate, which shows the recall remedy failed to operate as required. Mangino Chevrolet documented symptoms matching the recall defect, including abnormal ratio behavior. No metal debris was found in the pan, indicating the failure was not caused by wear. GM TAC also noted behavior consistent with a developing slip. GM first recommended full transmission replacement at my expense before acknowledging the recall. GM later authorized a valve-body replacement, which also failed. The dealership owner provided a written statement confirming that: (1) the recall remedy did not correct the defect, and (2) the valve-body repair did not correct it. On December 3, 2025, GM Customer Assistance attempted to close my case as “not recall-related,” despite the post-remedy lockup, limp-mode failure, dealer findings, and the written admission that the recall remedy was ineffective. The safety defect persists after recall completion, and GM has not provided a remedy that corrects it, as required under federal law. I am reporting this as a failed recall remedy and an ongoing safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

During driving at low speed 15-30mph with 4 wheel drive set to auto. 4 wheel drive engaged and rear wheels locked up. Turned off 4wd no issue. Upon arrival at the dealer a bad sensor was determined to have caused the rear wheels to not perform as designed. After resolving the issue now I hear rubbing metal noise from the drive shaft. Spoke to Chevy about the issue haven’t heard back.

My truck started acting sluggish like the parking brake was applied while driving. At a traffic light I put the vehicle in park applied and released the parking brake. I put the vehicle back in gear an let off the brake. The vehicle did not move so slightly pressed the accelerator. The vehicle still acted as if the brakes were applied. I could feel the slight movement and torque being applied but only slightly lurching. The traffic light turned green so I proceeded up to 45mph. A vehicle in front of me slowed to make a turn. Applied the brakes and nothing happened. I pressed the brake so hard that I lifted myself off the seat. I swerved to miss the vehicle avoiding a collision. Then warnings started popping up; "brake system failure max speed 62mph", "brake system failure max speed 42mph", Brake system failure", service traction control", "service trailer baking system". among others I was too busy to see all of them. I coasted to a stop in a nearby parking lot with visual and audible warnings still going. I shut the vehicle off then restarted it. Some warnings remained like traction control and the engine light. The vehicle appeared to be operating correctly so I drove it to a local dealer. they said there was a code for low voltage in the brake control module but couldn't get me an appointment for over two weeks. I took the vehicle to a regular mechanic who said what I described was impossible. That mechanic kept my truck for the balance of the day but could find nothing wrong. I no longer trust this vehicles brake system. In many scenarios the failure, were it to happen again could be catastrophic.

What component or system failed or malfunctioned, and is it available for inspection upon request? Based on information from ODI Resume EA25007 & Safety Recall N252494002, it is more than likely engine connecting rod bearing failure. How was your safety or the safety of others put at risk? I was traveling at freeway speed, 70mph when it occurred. Has the problem been reproduced or confirmed by a dealer or independent service center? 11/25/25 at 12:33 (pacific), I am currently stranded 190 miles from home and waiting for the truck to be towed to the dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has not. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Prior to Failure: Since I’ve owned the vehicle, I’ve notice slight ticking and slight knocking during cold start within the engine bay. At the time the noises seemed normal and not cause-for-concern. At Time of Failure: I was traveling on level grade on the highway when I heard a deep knock from the front, bottom left side of the engine bay. Within about a minute from the initial noise, I received a “check engine” warning light and a message of “ESC Warning” displayed on my instrument cluster. At that moment, I noticed the engine noise become more prevalent and constant. I immediately slowed and coasted to my next exit off the freeway.

Brakes would not release after driving a little ways the brake system failure warning came on. I stopped and killed engine and restarted but it lunged and I lost all braking. I pulled over to side of road and again killed engine a couple minutes I restarted it released. Then drove normal. ????

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the tailgate opened independently without warning. Upon investigation, the contact discovered NHTSA Campaign Number: 24V060000 (LATCHES/LOCKS/LINKAGES) and linked the failure to the recall. The local dealer was notified about the failure, and the contact was informed that the VIN was not covered under the recall, and the contact was provided with an estimate for the repair. The manufacturer was also notified of the failure, but referred the contact to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 50,000.

While driving it said "service ESC", "brake system failure" and then "trailer brake system failure" "max speed 62." Brakes when pressed would not work. Had to cruise to stop. When truck shut down and restarted it said "max speed 43" and check engine light came on. Truck was then towed to mechanic and waiting to be looked at/worked on.

There was a brake system failure and the brakes stopped working while going 50 mph

Making turn at slow speed. Possibly Transmission slipping and rear tire locking up. engine light turned on

The transmission quite working while I was driving down the road. Took my foot off of the gas pedal and my truck bogged down completely and had no power to it. It is at an auto repair shop so I am unaware if it could be inspected under request. Took time but was able to safely get off the roadway and out of traffic. It did the out of no where. Started having some issues this summer but no warnings lights ever came on, so I didn’t think much about it. Completely stopped in the middle of the road and had little to no power from the transmission to the truck to move off of the road. My truck is currently in an auto repair shop waiting on a new transmission to be installed. I had it towed to an independent auto shop from where it stalled. There were not warning lamps or anything at the time of my transmission quitting. Truck started to run rough and shifting hard this summer but without warning lamps I didn’t take it anywhere. When running on the interstate it was shuttering which I thought was due to possible tire out of balance. It would also hesitate to take off when put into drive. It had several of the same issues that Chevy had on other transmissions that were recalled within this same time frame.

The Engine began to make a knocking noise at ~62000 miles on the odometer. I assume it was bearing failure. MURREY CHEVROLET GMC diagnosed the problem as catastrophic engine failure with the repair being a replacement of the engine. There were no warning lamps. This is a 2020 Chevrolet Silverado High Country with the 6.2L engine.

Fan started running non stop, we overheated, engine cut out and says reduced power. This diesel engine has 80k miles which is nothing for a diesel.

Loss of power when driving and a shutter feeling when accelerating. I took the vehicle to the dealership for repairs and was told the torque converter was replaced due to it being faulty but problem still persists.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while his son-in-law was driving 61 MPH, the vehicle made an abnormal clanking sound and stalled. The driver pulled over safely. The OnStar Mobile App alerted the driver of an issue with the vehicle. The contact stated that the vehicle was making an abnormal ticking sound prior to the failure. Upon arriving to the location of the vehicle, the contact noticed an oil leak underneath the vehicle. The contact stated that he was a certified mechanic, and the vehicle was towed to the contact's Auto Repair Shop, where the contact determined that the rod had gone through the engine block. The contact called an unknown local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 80,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving approximately 40 MPH, there was an abnormal pop and ticking sound coming from under the hood. The check engine and several other unknown warning lights were illuminated. The vehicle was taken to a local independent dealer, where it was diagnosed with a failure in cylinder #7 and piston failure. The vehicle was not repaired. The local dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 99,600.

Ever since I bought the truck I have had a issue with the transmission after it heats up an around 57mph the transmission is stuttering like crazy fluids an filters has been changed an no change on the transmission operation. After talking to many shops states that my year model a style of truck has terrible transmissions this is a safety issue that needs to be looked in to. I’m scared to put my kids in my truck because of this. I have notified the dealer the Monday after I got the truck.

Driving at normal highway speeds, "service parking brake", "service engine", and "electronic stability control" lights illuminated on the dash with no prior warning. When attempting to accelerate, to maintain highway speed there was noticeable roughness to the engine along with a tapping sound. I slowed and made the trip back to my home under reduced power. The vehicle was towed to the dealer the following day per the dealer's service advisor instructions. Issue was diagnosed as a collapsed lifter, bent lifter rod and damaged cam lobe. Total repair cost exceeded $10,000. Internet search of this issue reports a number of drivers reporting similar issues with the Chevrolet 5.3 liter engine. If this issue had occurred in a more congested traffic area it could have caused an accident when my engine power was suddenly reduced without warning.

While driving on a residential side street my 2020 Chevrolet Silverado 1500 (81,996 miles) suddenly lost power steering and braking with no waring. Several messages appeared in the dash and the check engine light illuminated. I was able get the vehicle safely to the shoulder and put in park without power steering or brakes. At this point the engine stalled and would not restart. The vehicle was towed to the nearest Chevy dealer on 10/29/2025. The technician verified the loss of power steering, brakes, and several other codes and diagnosed the issue as corroded engine grounding straps per GM bulletin #23-NA-201. The grounding straps were replaced and the codes cleared. The technician test drove the vehicle and verified normal operation after the repair. I was responsible for paying the full cost of these repairs as my vehicle was out of warranty. I feel incredibly fortunate that this happened on a residential side street with no traffic. Had this failure happened on the expressway while pulling my 4,000 lb trailer, this could have been a fatal accident if I suddenly lost power steering, brakes and had the engine stall like it did. I see multiple complaints for this issue on the NHTSA website and the GM TSB for this issue dates back to 2023. I am shocked that this is not a nationwide recall yet. It is a significant safety threat to the driver and others. I also know this is not an isolated incident, as my service advisor at the dealer suggested it was probably the grounding straps before the technician even inspected my vehicle. It was pretty clear from our conversation that I was not the first vehicle they had repaired with this issue.

my 2020 High Country Deluxe 6.2 L87 GM Motor: At Every Cold startup, the engine sound is erratic and sounds like metal on metal for internal combustion for approximately 2 seconds until the newly designed two-stage, variable displacement vane-type pump oil sump pump. The biggest issue that I have with this design is, with a 2 stage pump, depending on the engine rpm, according to GM is Possible lower psi to pump the oil to the top end Valve assembly. In addition, the OW/20 oil IMHO is too thin and does not have the Viscosity to lubricate the motor properly. GM Fix (for 2021 -2024 L87 6.2 motors was to change the viscosity to 5W/30 Supercar Synthetic oil, add a leaf to the owners manual to dictate the oil viscosity change and changing the oil cap from 0W/20 to 5W30. 10-speed Hydra-Matic 10L80: Hard upshifts and downshifts intermittently and confusion of proper gears. There is a TSB regarding this specific Valve Body and torque converter issues. Finally: When deactivating DFM Random cylinders as needed by ECM-TCM-BCM, the lifters are staying in the collapsed state and cant return to full height resulting in bent push rods, rocker arm damage, Camshaft damage, crankshaft damage and Catastrophic engine Failure. It now seems that NHTSA has issued a New Federal Probe into the remaining 2019-2021 L87 6.2 motors.

Transmission jerky or slipping

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 71 MPH with cruise control engaged, the vehicle experienced braking and power steering failure. The Traction Control, Brake, Parking, Antilock Braking System, Electronic Fuel Control, and Check Engine warning lights were illuminated. Additionally, the Brake Assist failure, Steering failure, and Trailer Brake failure messages were displayed. The contact shifted into neutral and coasted over to the side of the road. After turning off the vehicle for approximately an hour, the contact was able to restart the vehicle and drove 40 MPH back to the residence. The contact stated that after the failure, the vehicle had to be shifted into neutral, and then the parking brake was activated to come to a stop. The contact stated that a diagnostic test confirmed the steering and brake failures. The contact used a diagnostic tool to retrieve DTC: C0580. An appointment was scheduled with the dealer, but the vehicle was not yet diagnosed. The contact discovered information related to NHTSA Campaign Number: 20V116000 (Service Brakes, Hydraulic), but the VIN was not included in the recall. The manufacturer had not been notified of the failure. The failure mileage was approximately 104,000.

Front left cv axle is making a noise like a metal to metal noise. There was a recall on the 2019 for the same reason. Mine is a 2020. Same problem.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that once the vehicle had warmed up, while driving at speeds of 50 MPH or higher, the vehicle shuddered abnormally while depressing the accelerator pedal, and the vehicle became difficult to steer. There were no warning lights illuminated, or codes displayed. The vehicle was taken to the dealer, who diagnosed that the torque converter and reaction carrier had failed. The transmission was scheduled to be replaced. The manufacturer was informed of the failure and opened a case. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 61,200.

Without warning (no warning lights or previous mechanical indications) the power steering failed making it extremely difficult to turn the steering wheel. Fortunately this happened while I was parking and not on the highway. The truck had approximately 48,000 miles on it at the time. (8/30/25) Repairs required replacing the rack and pinion steering and a heavily corroded "grounding strap". Repair cost was appx $3500

Summary: While driving, the transmission intermittently fails to shift and the truck has locked up and screeched to a complete halt approximately four times, creating a sudden stop/near rear‑end‑collision risk. Details & timeline: First symptoms were around 55,010 miles. On 10/13/2024 the Chevrolet dealer performed “SERVICE TRANSMISSION GM” (fluid & filter), but the condition continued. In April 2025, a shop documented DTC P0700 & P2727 (pressure‑control solenoid), burnt transmission fluid, and clutch material in the pan, and recommended replacing the transmission, transmission cooler, and cooler lines. Earlier, the transmission control module was reprogrammed, and oil cooler lines were replaced, but the truck still intermittently fails to shift while driving. The check engine light has illuminated during some events. Engine safety concern: During the same period the engine oil was found very low/“no oil on dipstick” with no external leaks; an oil‑consumption test was recommended, raising concern about internal engine damage and possible contamination from the transmission failure. Safety impact: The lock‑up / abrupt stop events occurred while the vehicle was in motion at approximately [~speed and road type, e.g., 35–55 mph on city/secondary roads], forcing hard braking by vehicles behind me. This presents a risk of sudden loss of propulsion and crash. Frequency: About four lock‑up events so far; shifting failures are intermittent and ongoing. Current status: Vehicle at ~73,000 miles. A Chevrolet dealer is being asked to perform a factory diagnosis and to submit a manufacturer goodwill/warranty review.

Just recently my power steering started cutting in and out in parking lots. I have seen that there is a ongoing investigation into steering problems with these trucks. I have not took it to a shop, because it just started and has only done it in parking situations. There are no lights or warning codes on the dash. It was about two weeks ago that it started. The vehicle is available for inspection upon request. I just would not like to experience it failing on the road.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle was shaking and vibrating abnormally. There was no warning light illuminated. The contact stated the failure was a recurring failure. The vehicle was taken to a local dealer and the contact was informed that the oil level was low, and oil was added. The dealer had not diagnosed the vehicle. The contact stated that the failure reoccurred. The contact had been checking the oil level and was constantly adding oil. The contact stated that the same dealer had changed the spark plugs and fuel injectors in January 2025. Recently the contact was unable to start the vehicle, and the vehicle was towed to the same dealer. The vehicle was not diagnosed; however, the dealer advised that the failure might have occurred due to a failure with the transmission. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was 136,888.

Lifter failure

Dear NHTSA Office of Defects Investigation: I am filing this formal complaint regarding General Motors' failure to provide a timely remedy for safety recall XXX and GM's inadequate response to a catastrophic transmission defect that has affected my vehicle twice, resulting in complete transmission lockup while driving at highway speeds. *SAFETY INCIDENT HISTORY My 2020 Chevrolet Silverado 1500 has experienced the transmission control valve defect described in recall XXX on two separate occasions, both while driving at approximately 65 mph on the highway. Each incident resulted in complete rear wheel lockup, creating an immediate life-threatening situation. Following the second failure, I had the vehicle towed to Huffines Chevrolet Plano [XXX] ) on August 18, 2025. UNREASONABLE DELAY IN RECALL REMEDY As of today, October 6, 2025, my vehicle has remained at the dealership for 49 days with absolutely zero action taken toward repair. The vehicle has not been evaluated, diagnosed, or repaired. The dealer states they have only one transmission technician to handle the massive volume of recalled Silverado trucks affected by this defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Several times my transmission has began to shift hard miss gears while hitting the brakes. Lose of power/hard shifts/ not shifting when it’s supposed to/jerking and or harsh shifting slipping delay in shifting slams into gear check engine light comes on after check engine light is on it continues until codes r deleted and or battery power is disconnected. This is a problem with codes like 0700/0716/0796 for the tranny control system sticking malfunctioning happens several times in the last year about every 3-4 months

VIN: [XXX] Component: Powertrain / Transmission / Recall Remedy Description of the Problem: Recall remedy applied in June 2025 failed. Transmission subsequently failed. On August 25, 2025, a Mangino Chevrolet technician confirmed in writing that the failure was “related to the recall that was previously performed.” My truck was previously in GM’s care at Van Bortel Chevy (Nov–Dec 2024), after the recall officially opened on 10/24/2024, but the remedy was not applied at that time. I was forced to continue driving thousands of miles with the defect still present. Despite the written admission that the failure is recall-related, GM Customer Care has only offered a 50/50 split on the transmission replacement (my portion ≈ $3,950.34 + tax) and is now attempting to reframe the issue as a maintenance problem. Transmission fluid service intervals are not the cause here — the federally mandated recall remedy failed to prevent the very failure it was supposed to address. This situation has left me without a safe, reliable vehicle. GM has acknowledged the recall remedy failed but is refusing to take full responsibility. I am requesting that NHTSA investigate GM’s handling of this recall remedy failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Truck experienced reduce power mode. Took to have codes ran and it showed 24 separate codes when engine light comes on. While riding down the road, truck will go into reduce power mode, shift automatically into 4x4, and several other notifications will appear. Taking to dealership and was told the electrical wiring harness was shorting out causing this issue. Cost around $700 for repair, happened one month later, took it back and no charge for the 2nd time. It is currently in reduced power now. Dealership stated to replace the wiring harness would cost over $3,000. Dealership stated this was a manufactures defect, but no recall was issued so all cost is on the owner.

After completing a GM assisted engine rebuild the transmission oil pump is failing and transmission shifting era tic.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 70 MPH and depressing the accelerator pedal, the engine failed and shut off independently. An independent mechanic and dealer were contacted. The vehicle was towed to an independent mechanic, and the contact was informed that the crankshaft had melted. The vehicle was then towed to dealer, where it was diagnosed and determined that the crankshaft had melted and there was a rod bearing failure. The engine was replaced, and the vehicle was repaired. The contact related the failure to NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The manufacturer was notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was 76,000.

With only 70,000 miles on the truck it started to have a hard shudder and wheels locking up. During the wheel shudder it would shift hard as well. We took it to a shop and they said it was our Transmission control module and that the transmission had metal shavings and would fail soon. They also said doing any service to these transmissions can cause failure.We were informed that the dealership is aware these transmissions are all failing. The cost to replace is over $6,500. The dealership should have to do an official recall for this. After some research i found that the dealership has acknowledged the issue by replacing the TCM and uploading new software to put the transmission into a fail safe instead of putting in a new transmission. The issues that the failure causes has made thousands of people have to get new transmissions before the service is even due. A quick search on Google states that 461,000 vehicles were effected and that a recall has been issued, but it has not been officially issued. We need a new transmission and should not have to pay for it on a truck that is so new and serviced timely.

Coolant control valve failure. Dealer inspected vehicle and it was confirmed that it needed to be replaced. Check engine light came on fan started spinning at a high speed and the vehicle went into low power mode. When I spoke with the dealer, this is a known issue so much to the point where the cooler control valve is on backorder and I’ve had to wait for over a month now. Projected cost to replace with labor is over $3000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at a moderate speed, the fuel warning light had appeared on the instrument panel. After fueling the vehicle at a gas station, the vehicle began to hesitate while depressing the accelerator pedal, with several warning lights, including the "Engine Power Reduced" and "Service ESC" illuminated. Due to the failure, the contact had the vehicle towed to a dealer. The dealer informed the contact that the starter needed to be replaced because the vehicle had failed to start. The mechanic performed a diagnostic test and discovered that the fuel injectors were defective and leaking fuel into the engine. The mechanic diagnosed the vehicle with engine failure and provided the contact with an estimate for repair. The manufacturer was notified of the failure but offered no assistance. The contact was then referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 68,000.

am writing to formally report a transmission failure in my 2020 Chevrolet Silverado 1500 and to request your assistance in addressing this issue. I purchased the vehicle on September 2020from Suburu Cobband it currently has approximately 143,000 miles on the odometer. Recently, the truck began experiencing serious transmission-related issues, including total failure. These issues developed without warning and have rendered the vehicle unreliable and unsafe to operate. After inspection by ALM Chevy, I was informed that the failure likely stems from a known issue with the torque converter or transmission valve body — problems that have been widely reported in 2020 Silverado models with the 8-speed automatic transmission. I have also learned that GM issued a recall for certain 2020–2022 models due to excessive transmission valve wear, which may cause the rear wheels to lock up. I am concerned that my vehicle may fall within the scope of this recall or a related Technical Service Bulletin (such as TSB 21-NA-199). Given the seriousness of the failure, the relatively low mileage, and the widespread nature of these transmission problems, I believe this may be a defect in materials or workmanship. I respectfully request the following: Confirmation of whether my vehicle is subject to any open recalls or service bulletins relating to the transmission. A warranty or goodwill repair of the transmission or related components. If parts are unavailable, an estimated timeline for repair or alternative transportation options. I am attaching copies of my repair estimate, service records, and proof of purchase. Please advise me of the next steps and whether further documentation is needed. Thank you for your attention to this matter. I look forward to a prompt resolution so that I may safely return my Silverado to the road. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The transmission skips and has trouble finding gears. This causes the truck to vibrate, be slow to accelerate, or lurch occasionally. The decrease in vehicle responsiveness and unpredictable behavior make the vehicle drivable, but less safe.

Engine shut off while driving and was unable to restart.

I am writing to bring to your attention an issue I've been experiencing with my truck's transmission. Recently, the transmission failed due to a torque converter issue, which has caused significant disruption for me. From my understanding, this is a known problem that hasn’t been adequately addressed by GM. As I'm currently in the process of getting the transmission rebuilt, I believe it is only fair that I should not have to bear the costs associated with this repair. I would appreciate it if someone from GM could reach out to discuss this matter further. Thank you for your attention, and I look forward to your prompt response.

Power steering locked up. Dashboard warnings "Service Power Steering Drive with Care, Service Trailer Brake System and Driver Assist Disabled"

While driving the active fuel management changed my truck from 4 cylinders to 8 cylinders. This is when I heard a loud bang and a bunch of lights came on the dash and my truck started shaking and shuttering. I was able to regain control of it, but I came close to crashing. I now require a whole new engine at 100000 miles. After talking to multiple shops this ks a known issue. While they dont always catastrophic fail, mine did and almost cost me to crash. This is a serious safety concern.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 70 MPH, the transmission independently shifted to 4-WD. No warning lights were illuminated. The contact stated that the vehicle decelerated to 55 MPH, and the rear wheels locked up. The contact stated that the failure reoccurred, the rear wheels locked up, and the vehicle went sideways. The vehicle was almost involved in a crash. The contact’s wife, small children, and grandchildren were occupants of the vehicle during the failure. The vehicle was driven to the residence. The contact stated that the vehicle failed to exceed 50 MPH while driving. The contact's wife was afraid to drive the vehicle. The OnStar system retrieved DTC: P0708 (Transmission Range Sensor Circuit High Input). Additionally, in November 2024, an unknown recall repair was performed to update the power train software. The dealer was made aware of the failure. The vehicle was scheduled to be diagnosed at a later date. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 58,000.

The transmission is locking up at speed causing a significant jump/ lurch in the rear end momentarily that sudden causes lane change. The dealer is telling me this is related to the transmission valve body recall however I received no warning and my truck has never gone into limp mode even though the recall remedy was supposed to provide a 10k mile warning. It would seem the determining factor is not being measured correctly or there are other contributing factors that are not being considered. This seems very dangerous and happened six times over the course of five miles before I could get the truck home and off the road.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 55 MPH, several unknown warning lights illuminated. The vehicle was towed to the dealer where it was diagnosed. The dealer became aware of an abnormal sound coming from the lifters and camshaft, which failed to create a misfire. The contact was informed that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 68,000.

On August 17,2025 I was driving on the freeway when I heard a loud bang and I thought my tire blew but it also felt like I hit something, however I pulled over and tires were ok. I proceeded to go again and this time if can feel my rear tire lock up and then let go. I pulled into a parking lot and my tires had some strips on them as if they where dragged.

The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 96,000.

Our truck would not start, we had to have it towed twice. We had a s Diagnostic run and the code was for the fuel pump. We had the truck towed to a local mechanic and they mentioned the open recall on fuel pumps for our make, model and year. We tried to schedule the appointment at the dealership for recalls, but our VIN was not on the list.

The failure mileage was approximately 24,155.

Rear wheels of vehicle locked up momentarily mutliple times while driving between 45 and 65 miles per hour. Originally happened multiple times while towing a travel trailer but subsequently happened again with no trailer being towed. No warning lights or other sign of a problem leading up to any of the malfunctions. After locking up for approximately a quarter to half a second, the wheels release and the truck drives normally. Sudden wheel lock up could lead to loss of control or cause a vehicle to collide with the back of affected vehicle. Issue was reproduced by dealer service department and they recommended a new transmission valve body. This seems to be related to the recall for the transmissions on the diesel models of this truck but the gas trucks were excluded from that recall.

My problem is the same as many others with the 3.0 Duramax engine. I h e the P0016 code indicating the the timing chain that can cost up to $10k and sudden engine failure if not repaired. My vehicle is only 5 years old and has 98K miles at the moment.

I was on a trip to Iowa and noticed a loud ticking noise starting in my engine. There was no warning lights on the dash to indicate any problems. I checked the oil and notice it was not registering on the dip stick. I added over a quart of oil and the noise continued. My truck was just at a dealer 2 weeks prior for an oil change and they noted that everything was good and in proper working order. No leaks or no other issues. I set up an appointment at a chevy dealer at the destination which I was traveling to for a check up. About 60 miles from the dealership, my check engine light went on. I immediately stopped and checked all my fluids which were showing normal ranges. I dropped my truck off for inspection and they advised me that my lifters need to be replaced. I authorized the repair and after the new ones where installed, they tested my truck and noticed that there was still a ticking noise coming from the engine and was not holding any oil pressure. They advised me that the motor needed to be replaced at a cost of almost $15,000. I will request all pictures and videos taken by the dealership for further inspection if needed.

Had sudden engine failure at 82k and have been told I need a new engine. Can't afford it, GM says there's nothing they can do to help cover the repairs. I have a new engine on backorder, nobody knows when it will be in, they told me they have other customers who have been waiting for new engines for months.

While driving in Southern Utah my truck gave me a Service ESC (Electronic Stability Control) Warning, Service Parking Brake Warning, and check engine light that was for code P0303. I had the vehicle towed to the local Chevrolet dealership and it was diagnosed with lifter failure and camshaft damage because of the lifter failure. Safety was compromised because of the failure of the ESC and the loss of power and stability of the engine. I didn't receive warnings prior to the failure. This appears to be a well-known issue with several service bulletins issued for the vehicle.

I noticed that the carpet behind the seat was wet and moldy in the truck so I started looking and noticed the rear window was leaking in two areas. This has obviously been going on for a while as it explains why the kids have been complaining about the smell back there. Since Florida is sub-tropical mold and mildew is a problem and a health issue. I investigated and found hundreds of complaints regarding this issue with failed sealant and cracks. I also discovered a service bulletin that describes the issue but GM refuses to fix it since they say it's not a safety or mechanical issue. Well, I happen to disagree with that since the leak causes the window to fog up and an unsafe environment for people to breath in mold spores in a small space. So, my visibility is impaired and I have to suffer with respiratory issues? This seems to be reason enough for them to perform a permanent repair at their expense, not mine and they can take it out of the designers pay, not mine. Can you help with this?

Just hit 65k miles and have had a transmission issue where it shutters back and forth and was quoted 6k to repair it

There was a significant oil leak that was diagnosed during a routine oil change in March of 2025. The dealership that identified the leak attempted to pass it off as something that was out of warranty even though the vehicle had an additional six months and 45,000 miles of warranty (3.0 diesel). The leak was significant enough that loss of oil could cause the engine to fail and result in a crash. Subsequently, another dealership identified the leak and repaired the seal around the lower crankcase. It did not repair the oil leak- there are three additional reports/complaints to file.

This is for the second oil leak that occurred in the 2020 Chevrolet Silverado with the 3.0 diesel engine. It was identified as a leak in the oil pan. The previous repair was for the lower crankcase seal. The service advisor at the dealership stated this is another problem area with the Chevrolet 3.0 diesel engine, and a defect from the manufacturer. He also mentioned it is a common repair they complete on these LM2 engine. It is worth noting, the initial repair didn't last 60 days before another oil leak presented itself. This is the second of four repairs that were done on this vehicle. **No loaner vehicle was given during the repair.**

The second oil leak repair and the first repair for the oil pan failed within one week of the previous repair. This is the third oil leak that occurred in the LM2 engine in the 2020 Silverado. It was identified as an additional leak in the oil pan which had already been repaired the week prior. This is a failure within seven days from the previous repair. I lost 1/2 quart of oil during a 650-mile drive back from vacation. I took pictures of the oil level before leaving and driving home. During our drive, we passed through an area called Yermo where it was 107 degrees at 11am. The two closest Chevrolet dealerships are either 45 minutes or 1.5 hours one-way. I was incredibly frustrated since imagine being stranded in 107-degree weather with your family on the side of the road unable to run AC. It is a serious life, health, and safety issue at this point. I called GM and opened a case expecting them to assist me with the issues with the truck. Fast forward to today, I spoke with Jill at GM, they closed the case without even reaching out to me. This was the third of four oil repairs that have been conducted on my vehicle and the LM2 engine. It isn't a safe engine to have. **No loaner vehicle was given during the repair.**

After three oil leak repairs in my LM2 3.0 diesel engine in my 2020 Chevrolet Silverado RST, you would think that would be enough to repair the manufacturer's defects, but it wasn't. I think the saying is fourth time is the charm? The third repair which was a second oil pan lasted a whopping 48 hours before leaking. This time it ended up being the timing chain cover that was leaking. Again, the service advisor mentioned that these are known to leak too due to a defect from the manufacturer. I even got a call from the service manager, and he said that anything area that could and does leak oil on these LM2 engines has been replaced and/or repaired, so I should be good for the future. I called into GM as per their instructions to update them on the fourth oil leak, and where the repairs were taking place. Fast forward to nearly two months later, and no one from GM attempted to contact me, and Jill stated that the case was closed and wouldn't disclose why. The only thing she could do was open another case. I declined since GM couldn't be bothered to address the issues they know they have in the LM2. The dealership the work was done in, the service advisors, the service techs, and the service manager all discussed in great detail the issues Chevrolet is having with the 3.0 diesel engine. GM knows this and refuses to address this. At this point, my vehicle spent 37 days in 2.5 months at the dealership fixing oil leaks that at any time could have caused engine failure and resulted in a crash. This truck is our dedicated family vehicle as my wife and I each daily Subaru WRX's. GM has done nothing and will do nothing. Someone needs to issue recalls to address the oil leak issues with the LM2 before it results in someone's death. I wish I wouldn't have wasted time contacting GM. I should have filed these complaints and got legal representation for the Magnuson-Moss Warranty Act. **NO loaner vehicle was given during the entire 37-day repair duration.**

When it gets hot it'll lose power at the pedal and it will randomly come back causing the drive train to jerk back and forth throwing full related codes that go away once the truck has cooled off. Took it to a shop and they couldn't get it to throw a code. This will be the third time it has happened. This time it doesn't throw a code

Lose of power at the pedal again not even 15 mins later. Still no code. Just extremely frustrating

Motor suddenly loss power and load knocking noise. After taking it to the dealer they said that number 3 cyl.connecting rod had an issue . This sounds like the same recall for the 2021 to 2024 6.2 engines. They gave me a quote for a new engine ( 20000) that was not available for 4 to 5 weeks if not more. I was on vacation at the time and ended up buying a new truck from them. I was not happy.

Rear window is leaking onto the carpet beneath it creating mold and could allow water to enter the SRS module. Currently i have a tray blocking that water but without that the SRS system could be affected by the water entering the cabin through the rear window.

Rear brake inner pads completely worn while outer pads look brand new at 35,000 miles. This appears to be due to the electronic parking brake not releasing quick enough but this condition almost disables the rear brakes and could cause an accident.

Shop has had the truck over two months and cannot figure out the problem will not go stuck in limp mode.

defective 8-speed automatic transmission (RPO MQE, 8L45) in my 2020 Chevrolet Silverado 4x2 (VIN: [XXX] , 102,000 miles), purchased used from CarMax Orlando (6375 S Semoran Blvd, Orlando, FL 32822). The vehicle required a $5,950 repair at AAMCO Winter Haven (1350 6th St NW, Winter Haven, FL 33881) due to persistent transmission issues, including shuddering, jerking, or delayed shifting.

Lost power steering in the middle of a corner..Almost but me into pole ..No warning..later on warning came on.Truck has 32000 miles on it

The Rear Window leaks when it rains on the truck. I brought it back to the GM Chevy dealer and they applied a sealant. it immediately leaked right after. the truck now smells musty and im assuming there is mold growth. it has been at the dealership for the past two weeks while they try to figure it out

No power steering alert showed up to service power steering. Very dangerous driving and power steering goes out.

Initially, turbo charger issues. Dealer after 2 weeks corrected issues with the turbo charger. We were provided loaner. Dealer took 28 days, the second time, to supposedly remedy Transmission/shifting issues. First we were told it was a valve port body. Then we were told they had to remove the pan, etc., all part of the process. Then the parts were on backorder. Finally, at the 11th hour, they installed a rebuilt transmission. Without a loaner for 2 weeks. Got the truck back and within 24 hours, the truck suddenly lost power steering while driving around curve at aprox.30 to 35 mph., check engine light on, power steering light on, trailer brakes warning light on, etc. Had it towed back to dealer in the morning and told it would be a priority. Called at 5pm. Truck has not been seen. It's not a car. It's a work truck. Seems the dealership is swamped with silverado trucks with similar transmission issues waiting for valve ports. No loaner vehicles to be had the second time after 2 weeks. Not sure what they will tell us tomorrow.

Lifter failure on the 5.3L L84 engine. Due to Dynamic fuel management that come with the trucks.

Having failure with the engine coolant control valve. Have taken my truck to the dealership for overheating and they always come and say that they can’t find an issue. They also informed me that I need to bring it back when my motor blows a head gasket which is complete bull.

There is an issue with the wiring harness that causes vehicle to lose power. Dealership says manufacturer defect because designed with harness cover is too thin and is to close to engine so burns wires. Many other users have complained of this issue and is frequent in this model.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while at a complete stop and depressing the accelerator pedal, the vehicle jerked. The check engine warning light was illuminated. The vehicle was taken to an unknown dealer, where it was diagnosed that the transmission was shifting hard. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the vehicle was out of warranty. The contact was referred to the NHTSA Hotline to file a vehicle safety complaint. The failure mileage was approximately 40,000.

About 3 months after the 5 year 100000 mi warranty with only 70000 miles on the duramax diesel engine the exhaust brake part of the engine emissions/exhaust split along the weld. Have seen a number of these reported on the internet as well. Sounds like a manufacturing problem. The vehicle's check engine light came on and it's now at the dealership getting a new exhaust brake housing and bracket replaced. If this was in California or the 12 states listed would be covered for 8yrs/100000 miles.

Tranmission rebuild at 70000 miles

Engine seized my truck has been at the Chevorlet Tempe dealership I filed a claim with GM still no response.

I had the lifters and camshaft fail in my truck as a result of the faulty fuel management system GM put in these trucks during these years of manufacturing. I was driving my kids to an appointment when they failed in the middle of the highway, leaving the truck unable to run. I have reported the problem to the dealer as well as reported to GM directly. I have spoken with 3 different garages, all of which have made it a point to tell me this is a common issue in these trucks. Prior to this happening, there were no lights on to warn me of this problem. The repair cost is $12,000 and that is to put the same parts in the failed the first time. I don’t know many consumers that can afford the costs of these repairs when GM knows this is an issue but refuses to do anything about it.

Having transmission issues like other silvardos but not included in recall

Having transmission problems but include in recalls like other silverados

My 2020 Chevrolet Silverado 1500 LT with the 3.0L Duramax diesel engine has experienced three separate failures of the coolant control valve over a span of less than two years. Each failure resulted in the vehicle entering reduced engine power mode, which drastically limits acceleration and the ability to maintain safe driving speeds — particularly dangerous on highways or in heavy traffic. Chronology of Failures: October 2023: First coolant control valve failure. Part was backordered. Repair took ~6 weeks. June 2024: Second failure of the same part. Another 6-week delay in repair due to part availability. June 2025: Third failure of the same part. Vehicle is currently inoperable and unsafe to drive. Each time, the failure triggered a check engine light and immediately placed the truck into reduced power mode. This issue significantly compromises driver safety, especially in high-speed or congested environments, where limited acceleration can increase the risk of collisions. Safety Concerns: Loss of acceleration power at critical times (merging, overtaking, etc.) Unpredictable vehicle behavior Extended unavailability of parts leads to prolonged periods without a functional vehicle Possible underlying design flaw or recurring part defect Given the recurrence, safety risks, and the number of similar complaints I have seen from other owners, I believe this is a widespread and systemic defect that deserves NHTSA investigation. Requested Action: I urge the NHTSA to investigate the frequency and root cause of coolant control valve failures on the 3.0L Duramax engine in the 2020–2022 Silverado models. This is not an isolated incident, and repeated failures of a critical engine cooling component warrant a safety recall or technical service bulletin (TSB) requiring redesign or replacement with a permanent fix.

Transmission is sputtering when trying to shift. Mostly at low speeds it's extremely jerky like it doesn't want to go. Had Transmission fluid and filter changed, but it did not help.

Lifter failure and miss fire

I was driving and came to a stop at a red light. When accelerating on green the transmission would not go into gear, stalling my vehicle. Nearly causing the vehicle behind me to rear end me. The vehicle eventually went into gear and started to slowly accelerate with shuttering of the transmission.

Was driving on the interstate on [XXX]. While driving, the truck suddenly slowed down and lost power. The check engine light came on and then after about a minute a message popped up on the dash saying that the truck was in reduced-power mode to prevent engine damage, or something like that. It slowed to roughly 50mph and I had to drive for maybe 5 miles to reach the next exit, narrowly avoiding collision from behind with cars driving upwards of 75. Pulled off the road to the first parking lot, then got towed to the nearest Chevy dealership in Shawnee, Oklahoma. The diagnosis was a blown connecting rod that had occurred while driving on the interstate, resulting in a necessary total engine replacement. The truck was repaired in Shawnee, Oklahoma at the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my truck the engine completely shut down. All the dash lights came on initially but then only the check engine light stayed on. My truck never would start back up after that. It was towed to GM dealership who diagnosed catastrophic engine failure.

2020 Chevy Silverado LTZ 6.2 V8 10 Speed. Started having issues with hesitation/shudder. Dropped off at a Chevrolet dealership for a diagnostic. The dealership pointed to a potential transmission issue. After having the truck for several days, they reported nothing wrong. Said they drove the truck, checked the transmission fluid, and couldn't find any issues. Picked up the truck and took it to a local repair shop. That shop drove it, but could not re-create the issue I was describing. I opted to have the transmission fluid flushed in hopes of fixing the shudder/hesitation I was feeling. After picking up the truck and driving it a couple hundred miles, the issue was still present. I made another appointment at the same local shop. This time, they called me saying the issue I'm feeling is the same problem that's been happening to these engines, the dreaded AFM (Active Fuel Management) system is starting to fail. I was told by the shop it's only a matter of time before the entire engine fails. The only way to fix the issue is to delete the AFM system by removing the old parts within the engine and replacing with new parts that do not use the AFM system. This would cost approximately $6,000 to complete.

Odometer Fraud. The contact was attempting to purchase a 2020 Chevrolet Silverado 1500. The contact stated that while attempting to obtain a loan from the bank for the vehicle, it was discovered that there was a mileage discrepancy after obtaining a Carfax report. The vehicle was a private sale. At the time of the initial inquiry on Facebook Marketplace, the vehicle mileage was 63,000. The contact discovered that the mileage was 203,000.

When accelerating the transmission shakes violently under the hood. It shakes so bad that other vehicles can hear it the vibration is intense until you take your foot off the gas and then try to accelerate again it happens a few times then it’ll stop until the next red light. Slowly accelerating makes it worse but doesn’t matter either way.

Was driving on highway and vehicle went into "engine power reduced" and dropped from 60mph down to 35mph and then steadily decelerated down and wouldn't go over 18mph. Per mechanic it is the engine coolant control valve and the part is not available and could be months to a year before the part is available. Online shows this is a widespread issue with GM / Chev vehicles but no recall has been ordered and parts not available anywhere. Completely unacceptable to pay $65000 for a vehicle that is just barely 5 years old and have this kind of issue and manufacturer doing nothing about it.

Lost power steering! Almost impossible to make any turns. The dash has ESC fault and power steering fault. Says drive careful! How can I drive careful if I can't turn the truck? Only 79k miles! GM must recall their bad design and replace it with a design that is proven not to fail!

When a Check engine light is on it's for a low voltage on the charge air coolant sensor, took to the chevy dealer, they replaced a connector to the sensor, at a cost of $600 never got off lot, light returned, they then said I need a new engine wiring harness at a cost of $10.000, the dealership said this is a problem with these trucks and GM knows about it but won't recall them. Now I'm struck with a 5-year-old truck that I can't use, When this light is on, I also receive an Emission system warning, and the truck deregulates and goes in limp mode. as speed is reduced it becomes dangerous to drive in traffic, as GM knows about this, they should recall these trucks and fix the problem, they even say it's because cutting corners on the wiring harness cover causes this problem. as a senior living on a fixed income there's no way my wife or I can get this repaired, so were forced to drive it in limp mode until it dies on us, hopefully not in heavy traffic.

Vehicle started and behaved as expected when leaving my home and for a dozen lights or so between my home and place of the incident. While stopped at a red light, the auto stop function shut the truck down as normal. On re-start when getting green light, after releasing brake pressure, the start up was belabored for two turnovers before starting up. As I pulled off the stop with a green light, the dash lights illuminated and display started rolling through system failures, one of which was the brakes system and ESC. I cautiously proceeded through my turn to a thankfully quiet intersection as the brakes were completely unresponsive. I had ZERO brake function. I was able to slowly come to a rolling stop enough to get the truck in park where I turned it off and back on and the brake function returned. I cautiously drove to the local chevy dealer where I was informed that the battery drain pulls from low voltage when it needs extra power for start up. This is utterly terrifying that it is even possible for the battery to start the truck WITHOUT ANY BRAKE FUNCTION. Had this happened just two lights before or after where I was, it would have been a news headline. I could have easily been headed up and over a bridge leading to a catastrophic event at the bottom where I would have been completely unable to stop my truck by any means other than a collision. I would have preferred a dead battery at a red light. Seems a whole lot safer. I'm now stressed beyond measure at the thought of some failure in the future that could lead to another event such as this. My truck is now a nightmare wondering what electrical malfunction is going to put me and/or my wife and daughter in a life or death situation, let alone others on the road. This shouldn't even be an option for the truck to start at the expense of a critical safety function. Not to mention there is no function for the auto start stop system to be deactivated permanently by my choice. I am beside myself and scared to drive.

I am writing to formally lodge a complaint regarding my Chevy vehicle, which is experiencing significant engine issues. The motor is knocking, and the check engine light has illuminated with trouble codes P0011 and P0016. These codes indicate problems with the camshaft and crankshaft timing on Bank 1 (driver's side in a V6/V8 engine). Specifically, P0011 signifies that the camshaft timing is over-advanced, while P0016 points to a correlation issue between the camshaft and crankshaft positions. These issues are often related to the Variable Valve Timing (VVT) system and may be caused by faulty camshaft or crankshaft sensors, timing chain problems, or solenoid issues. This situation directly correlates with a recent recall affecting similar VIN numbers for 2021-2024 models with similar engines. An independent service has confirmed that my truck requires a new engine, which aligns with the issues addressed in the aforementioned recall. I urge the NHTSA to investigate this matter further and consider extending the recall to include my vehicle, as the problems I am experiencing are consistent with those covered by the recall.

Oil pump went out. Got it repaired. Then, a few days later, while driving on the freeway at 70MPH the engine made a lot of noise then quit in middle of the freeway leaving me vulnerable to being hit. Was able to coast in neutral to the edge of the road. Has 73000 miles on it. Dealer says I need an engine replacement after just spending $5,500 for oil pump replacement. Has been at the dealer over a month and no replacement engine is available.

The engine seized up. Yeah, the truck is at a trusted mechanic and he told me that the engine seized. No warning signs. The truck wouldn't start and the engine light was on.

The lifters failed which caused the camshaft to destroy itself. I am now looking at having to replace my entire motor because of this. This is a similar problem to the current recall going on with the 2021 through 2024 trucks with the same motor. I have 146,000 mi on my truck

Cylinder Four misfire code. PO304 Dealer has discovered lifter failure. Total to replace all lifters on effected side $4300.00 Vehicle is garage kept and serviced per required dealership. All service records have been kept. No other issues with Truck 83K miles.

The contact owned a 2020 Chevrolet Silverado 1500. The contact stated that while stopped at a stop light, he observed smoke emanating from the area of the vehicle between the cab and the bed, prompting him and the other occupants to quickly evacuate. Within moments, the vehicle caught fire and was engulfed in flames. Local emergency services arrived and were able to extinguish the fire. The contact was informed that fire investigators on scene determined that the fire had appeared to originate in the electrical system associated with the seat belt located behind the rear passenger side seat. No warning lights were illuminated. The vehicle was towed to a tow yard and was likely to be deemed a total loss by the contact's insurance provider. A fire report was filed. A police report was filed, and no injuries were reported. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 19V814000 (Seat Belts); the VIN was included, but the vehicle had already been repaired. The manufacturer was not notified of the failure. The failure mileage was 100,000.

This transmission has shifted terribly since day 1. It currently has 114,000 miles. It would slip gears going up an incline. I was told the fluid was too slick. Fluid change at 30k. Started to stumble on downshift again. Fluid / filter change done. Brass, metal in filter/ pan. It will downshift so hard that it feels like you are getting rear ended at a stop light. 1-2 seconds after a complete stop, bam. Been down 9 weeks.

Loss of power in my power steering due to corrosion of a ground strap. Found service bulletin 23-NA-201 issued 12/23 for the exact problem. The dealership stated there was no bulletin or covered under warranty and is being replaced with cost to myself. I had intermittent low speed "jerking" occasionally a few days before up to the incident.

Randomly. The power steering has stopped working. There is a widely reported issue with the power steering in 2020 Silverados and this model now needs to be included

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at approximately 75 MPH, the electronic stability control (ESC), traction control, and check engine warning lights illuminated. The contact stated that several safety features failed to operate. The contact stated that there was a popping sound coming from underneath the vehicle. The contact pulled over to the side of the road to turned off the vehicle and waited before restarting the vehicle; however, the failure persisted. The vehicle was taken to the dealer but was not diagnosed. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 65,000.

My husband was driving our family truck onto the highway to merge into traffic, when he lost all engine power, several dash lights turned on, and a clanking noise started. This was an extremely dangerous situation because the truck stalled, while trying speed up into highway traffic. He swerved to avoid cars and pulled off to the right shoulder. This a major safety issue because if either of my teenage daughters had been driving the truck, they would likely not have been able to avoid an accident! Mechanics confirmed the truck had suffered a catastrophic engine failure while driving. The dealership confirmed a lifter failed causing the damage. They said the whole engine had to be replaced. GM offered to pay half of cost, proving they know this is an issue. The truck's not even 5 years old, so the fact that engine would just stop while driving, when we had kept up with regular maintenance, sounded bizarre to me. I researched online and learned of 2 class action lawsuits (CA & MI) claiming GM knows about this defect in their engine and continuing to sell trucks with the same safety issue. Not more than 2 weeks after our incident, hundreds of thousands of the 6.3L engines were recalled after a NHTSA investigatio. GM has issued several service bulletins internally on "failing lifters", but has not told the public of the safety hazard. The service bulletins acknowledge the issue, recommending GM mechanics use a lighter oil (SAE-0W20 instead of the customary SAE-0W40) or change the oil more frequently. (service update N212353840). But car owners don't know this! GM is putting lives at risk, as no one expects their engine to completely give out while on the highway. Thankfully, my husband has been driving for 35 years. Had it been a younger, more inexperienced driver, they would not have been able to recover from the engine failure, especially while merging into high speed traffic - causing a crash, injuries and possibly death. The public deserves to know.

A few month ago this 2020 Silverado check engine came on in the middle of driving. It stopped shifting and almost caused an accident because it wouldn’t stop. I took it to the dealer and they found nothing wrong. Today, it is doing the same thing with faulty shifting, especially during first and second gears and when I initially accelerate. It is jumpy and worried and accident will happen if the car stops shifting like before. The check engine light is on again

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the front wheels seized, and the contact was forced to pull over to the side of the road to restart the vehicle. This failure reoccurred a second time and while pulling over the front wheels seized, and the brake pad and rotors were visibly red. No warning lights were illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

My transmission keeps shuddering my whole vehicle after the new software was installed GM claims it’s fine and normal when in fact it’s going to cause an accident.

Transmission shudders started around 65k miles. Shop said it was recommended to do a transmission flush. We did that. Now at 72000 miles the transmission is locking up. It has been inspected by a reputable auto shop and they stated it needs a new transmission. The engine light came on when this issue happened. I was in the middle of traffic at a stop and when I started going it stopped abruptly and threw me forward. It was so violent that I thought I was rear ended. It did it two more times.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while her husband was driving 55 MPH, there was an abnormal sound coming from the vehicle. The driver pulled over to the side of the road and inspected the vehicle. The contact stated that her husband observed that the driver’s side front wheel had detached. The vehicle was towed to the residence. The vehicle was then towed to a dealer where it was diagnosed and determined that the control arms, rack and pinion, and ball joints had separated and needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 88,907.

2020 Chevrolet Silverado with 72K miles has a bad Transmission Torque Converter. Warranty expired 2 months ago and will have to be replaced in the next 30 days. Had the truck checked out at a local transmission shop that said this is happening on every v6 Silverado that is being brought in.

I am reporting an issue with a 2020 Chevrolet Silverado 1500 equipped with the 3.0L Duramax diesel engine. The vehicle experienced a failure of the NOx Sensor Position 2, which significantly impacted performance and emissions compliance. GM previously issued Emission Recall N212351211 (March 7, 2023) for other diesel Silverado models regarding improper ECM detection of NOx sensor faults. The issue in my vehicle appears functionally identical, yet this engine and model were not included in that recall. The sensor was replaced and reprogrammed at a Chevrolet dealership at the owner's expense. After contacting Chevrolet, a customer retention check was provided, covering roughly half of the total cost. While appreciated, the remaining cost burden remains significant. If this model is eventually included in the recall, it may allow for full reimbursement and support for other affected owners. Online forums show that many 3.0L Duramax owners are experiencing similar failures, suggesting this may be a widespread and systemic defect. Due to the strong similarities with the recalled condition in other models, I respectfully request that NHTSA investigate whether this recall should be expanded to cover additional affected vehicles. This issue presents both reliability and emissions compliance concerns. In addition, the vehicle developed a separate mechanical/electrical problem shortly after the NOx sensor failure. Because it involves different systems, I will file a separate complaint regarding that issue.

I’m reporting a safety concern involving a 2020 Chevrolet Silverado 1500 with the 3.0L Duramax diesel engine. The vehicle went into limp mode and died on the side of the road. AAA installed a new battery, which temporarily restored operation, though the “Service Charging System” warning remained. I drove it home, let it sit for several days, and then took it to a Chevrolet dealership. Although the warning light had cleared, I brought it in out of caution. The first dealer diagnosed a failed alternator and recommended replacement at a cost of $2,158.75. I was also told the vehicle was not included in any active recalls related to this issue. Believing the price was high and wanting a second opinion, I went to another Chevrolet dealer. They ran the same diagnostic and found no issue with the alternator or generator, charging only a diagnostic fee. They also said if the alternator had needed replacement, the cost would have been around $1,300. I mentioned to both dealers that I had seen similar alternator/charging system failures recalled on other 2020 Silverado models. Online forums and customer complaints suggest that many Silverado 1500 trucks with the 3.0L Duramax are experiencing similar problems, indicating a potentially broader issue. Given the inconsistency in diagnostics, the significant cost discrepancy, and the number of similar consumer reports, I believe this issue may be more widespread than current recalls reflect. I respectfully request that NHTSA investigate whether the existing recall should be expanded or if a new recall should be issued for 2020 Silverado 1500 models equipped with the 3.0L Duramax. This issue occurred shortly after a separate failure related to the NOx sensor, which I am submitting under a separate complaint.

8 speed transmission failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, there was a ticking sound coming from underneath the hood of the vehicle. The contact stated that the sound was evident when the vehicle was started, and while the vehicle was idling. The check engine warning light was flashing, and the vehicle was shaking while idling and while driving at various speeds.

The transmission has been slipping and shuttering which shouldn’t be an issue at 119,000 miles. This opposed a huge safety risk for me and my girlfriend on the highway. I was driving and it shuttered so bad i had thought the wheel was loose and coming off. I had to pull over on the highway to check the lugs and came to find out it’s the transmission, because it shuttered numerous times after. On top of that the entire trip was the transmission shuddering slightly making the wheels cut the the left and right. But throughout the trip, it had a slight shutter the entire time and a couple of big shutters, and one very large shutter that had my girlfriend think I ran over a bunch of wood in the road resulting in me pulling over being in danger and possibly wrecking from the shaking, and having to exit my truck on the side of the highway with 18 wheelers and other vehicles flying at 80+ miles an hour. Besides the safety issue, there should be no reason for these transmission going out like this at 60k miles and 100k miles it’s extremely cheap of GM and a huge hazard to many families.

Transmission is changing out very hard in each gear. On tonight while I was driving, I lost speed on the interstate and when I push the accelerator, It was like back wheels were locked up. I left it at the next exit gas station and came back and towed it home. Lucky I was able to put hazard lights on and get off the side of the road but it was very slow speed. Yes I have had it look at certified dealer under Cheverolet. It was no warning light. I was going 65 and in a split second the rpm went up high and I was doing like 25. Once I finally made it to the gas station and got out the truck smell like a burning smell

I am reporting an issue with a 2020 Chevrolet Silverado 1500 equipped with the 3.0L Duramax diesel engine. The vehicle experienced a failure of the NOx Sensor Position 2, which significantly impacted performance and emissions compliance. GM previously issued Emission Recall N212351211 (March 7, 2023) for other diesel Silverado models regarding improper ECM detection of NOx sensor faults. The issue in my vehicle appears functionally identical, yet this engine and model were not included in that recall. The sensor was replaced and reprogrammed at a Chevrolet dealership at the owner’s expense. After contacting Chevrolet, a customer retention check was provided, covering roughly half of the total cost. While appreciated, the remaining cost burden remains significant. If this model is eventually included in the recall, it may allow for full reimbursement and support for other affected owners. Online forums show that many 3.0L Duramax owners are experiencing similar failures, suggesting this may be a widespread and systemic defect. Due to the strong similarities with the recalled condition in other models, I respectfully request that NHTSA investigate whether this recall should be expanded to cover additional affected vehicles. This issue presents both reliability and emissions compliance concerns. In addition, the vehicle developed a separate mechanical/electrical problem shortly after the NOx sensor failure. Because it involves different systems, I will file a separate complaint regarding that issue.

The oil coolant cooler is leaking oil into my antifreeze reservoir, but nothing is in the oil pan, which could cause damage to the engine a very expensive fix, and this should be covered under drivetrain by all means

I have the L87 6.2 liter V8 engine from General Motors. I had sudden engine failure. Apparently the rods and bearings are bad. It is the same problem as the recall issued for 2021-2024 vehicles, exept for my truck is a year 2020.

Lifter issues, loss of power, flashing check engine light

On [XXX] I pulled off from a Red Light and vehicle started flashing codes. I slowed down and engine was missing. I had vehicle towed to Gilmore's Auto Center in Culpeper Virginia. The truck was diagnosed later that day as a Rod Bearing failure. The engine gave no warnings prior to that day.

Employee was driving company car on backroad, started to rev high im assuming from trying to accelerate. Car started to slow and was pulled into a parking lot and towed to dealer. Upon inspection it was shown transmission cooler lines broke at crimps and quoted 2K to fix just the lines

The vehicle was being used in a normal daily driving routine. I was stopped(fortunately) at a traffic light. The light turned green and I went to proceed and began to press the gas pedal and the engine made a loud pop noise and began to barely stay running. I brought the vehicle to the shop(GM dealership) for diagnosis and repair. The motor had to be rebuilt new camshaft, lifters, etc. The vehicle is also having transmission issues, heavy vibration, hard shifts and constant fluctuations in the rpms while maintaining a set speed. The transmission issue still has not been resolved.

My truck rpm goes idle while driving also a loud knocking sound when accelerating

chevy has a well known issue with lifters failing in the 5.3 motor because of the afm. it has failed on me twice and had to pay twice to get this fixed and i’m concern one day the engine will just blow like other people have complained about. i even went to the dealership and even spoke to the part department and they have admitted this but no fix for it has been put in place. we need a recall on this motor that’s effecting thousands of people.

chevy Silverado shakes at 20, 40,65 and 70 mph chevy shake

While highway driving on 4/8/2025, for the 3rd time in 3 months, engine light came on and I lost all control of my cruise control, parking brake disabled and loss of engine power immediately reducing my highway speed to approximately 50 mph which was very dangerous. I had to cautiously return home & called the Chevy dealer immediately. They had repaired the lifters twice before, with the most recent repair on the lifters and push rod just one month earlier. This second repair was covered under their repair warranty. Currently, it took about 10 days before a loaner car was available (after a poor google review). To date (4/30/2025) I have not received ANY feedback from the dealer (Starling Chevrolet in Mt. Pleasant, SC) regarding any repair or engine diagnosis. The symptoms of this third failure was just like the previous two failures (3 failures in 3 months!). I feel like this vehicle has Major issues as I have also had to have the radio/infotainment system replaced twice since the original purchase. PLEASE have Chevrolet do an engine recall on their 5.7 liter engine!!

While traveling on a rural state highway, the #8 lifter bearing failed, causing the engine to lose considerable power and the dash light to come on. No advanced warning of engine problems was noticed prior. The transmission also went into limp mode not allowing the vehicle to shift gears. At the same time the ABS and ESC systems also went into a safety mode diminishing the stopping power of the vehicle. Upon inspection by a licensed mechanic it was discovered that the #8 lifter bearing and the camshaft were both damaged at that time. Total replacement cost was over 10k and it took almost 6 months to find a rebuilt L87 engine at that time because there was almost no supply available as a result of these engines having multiple failures nationwide

I just saw a recall for 2021-2024 vehicles for connecting rod/crankshaft engine components. I am not 100% sure that i have the same problem but my warning signs are the same. For example, there is a knocking sound in engin, it shifts abnormally and it hesitates and has reduced propulsion. I talked to several other Trail boss owners that had to have their Lifters repaired so maybe it is that? These problems are happening to everyone prior to even hitting 70k miles. I cannot afford to fix this if it is a problem that shouldnt be happening in the first place, due to crappy manufacturing.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 75 MPH, the vehicle lost motive power, with the check engine, Service ESC, and the “Service Parking Brake” warning lights were flashing. The vehicle was towed to a dealer where it was diagnosed and determined that the engine was blown, and the engine needed to be taken apart for additional diagnostic tests. The vehicle was not repaired. The vehicle was then towed to an independent mechanic where it was diagnosed and determined that the cam phaser and lifters had failed and the engine long block needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 104,000.

Transmission slips, jerks, delayed shifting symptoms consistent with technical service bulletins and known recalls on later models. Add that it was purchased new and is still financed

The manufacturer was made aware of the failure. The failure mileage was approximately 59,000.

Driving vehicle down freeway about 75mph heard noise and truck shut speeds down to about 60mph on a major freeway. Per mechanic lifter has collapsed and it has been a common issue that Chevy knows about. He said that it could have been alot worse by seizing the engine and causing harm to drive or other people around causing a major accident. There is a major safety issue to life and or death caused by this issue that has NOT been a concern and causing people to pay over $5000.00 for repairs. Chevy has known about the faulty lifters for years and doesn't seem to care about safety concerns.

On Feb 10, 2025 while in busy mid-day traffic on the highway going 55mph my vehicle without any warning signs or warning messages on dash, or dash indicator lights suddenly went into limp mode , began making a loud knocking from the engine, and started shutting down. I stopped the vehicle as soon as I safely could do so and had it towed back to the selling dealer for them to diagnose the issue. The dealer then informed me that i had a bent lifter on the left bank but they did this based on codes and not any tear down. They referred me to another local dealer. I had my vehicle towed there where they also stated lifter. Once they began to replace the lifters on the left bank scarring was found on my #3 cylinder wall and at that point I was told that my truck had catastrophic engine failure and the engine would have to be replaced. They also told me that my truck had no oil in it and the issue was caused from carbon build up. I have had every maintenance service performed on time and at the selling dealer and have all service records. I was not overdue on maintenance. I have never been told about any oil leaks or any other issues that needed to be resolved on my vehicle. I had driven the truck the night before with no issues.. There was no oil on the ground or under the vehicle for them to say there was no oil in the vehicle. I was never told that i needed spark plugs due to carbon. I believe that this has to due with the AFM issue that GM is well aware of. I had to purchase another vehicle due to the damage that was found on this required an engine replacement

The engine failed while I was driving. It started to run very rough and then the check engine light came on as well as multiple other lights. I limped it to my mechanic who found that cylinder #4 had failed and rotated which tore up the cam shaft. Total damages came to 10,404.28. I have all receipts. Safety for myself and others were impacted because it lost power immediately and could have put me or other motorists in a position to react quickly not to crash.

Engine (v8) lost power and made terrible noise at 72,000 miles. Dealer installed a remanufactured engine and charged me $5109 and took 12 weeks to complete the work. GM claimed there were “unaware” of any issues with these engines even though an internet search showed tons and f people with the same problem.

The 2.7L turbo engine failed. The truck is available for inspection. All maintenance has been up to date. It was recently serviced for a seperate recall. The truck gave a reduced engine power message and within minutes lost power. A truck of this age, with maintenance done regularly should not experience engine failure.

The engine seized unexpectedly and without warning during driving. Being sudden and without warning it risked the occupants of the vehicle being injured as they struggled to get off the road and out of harms way on the road. The vehicle was taken to the nearest Chevrolet dealer to be inspected where we were told that the engine had suffered a total engine failure and would need to be replaced entirely. The vehicle WAS inspected and damage confirmed by the dealer at that time. Prior to the failure there were no warnings of any kind.

The contact stated that while driving 50 MPH and making a turn in the opposite direction, the vehicle lost motive power and there was an abnormal knocking sound coming from the engine. There was no warning light illuminated. The contact was able to pull over to the side of the road. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the rod and the lifters had failed, causing damages to the upper half of the engine. The dealer replaced the gaskets, the rods, the guides, the lifters, the camshaft, and the transition kit. Additionally, and oil change was performed. The vehicle was not covered under warranty and was repaired at the customer's expense due to the mileage. The contact stated that while driving approximately 65 MPH on another occasion, the vehicle made an abnormally loud clunking sound and lost motive power intermittently. There was no warning light illuminated. The contact pulled over to the side of the road. The contact drove back to the residence. The vehicle was taken back to the dealer, where it was diagnosed with cylinder #8 intake valve failure. The vehicle was repaired at the contact's expense.

The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 86,000.

Vehicle transmission locked up. I see safety recalls for 2019 and newer but mine is not on the list. I’d like to get the GM 1-year/1500,000 mile warranty they have issued.

Rear tires repeatedly locked up at highway speeds. Causing engine damage.

At approximately 68K miles, the torque converter failed. Luckily it started going out and we could feel it. It would surge/shudder while driving on the road. We had to have the torque converter replaced at $5k. A dealer replaced the parts. At approximately 90K miles, the lifters started making a loud pinging noise. It turns out the lifters had issues which lead to them being replaced along with the camshaft. It could have failed on the road and left us stranded. The sound of the lifters alerted us. A local shop fixed the issue at a cost of $9K.

Had a check engine code and the dealership diagnosed the problem as being the coolant control valve. However being still under warranty they said that part is no longer covered under powertrain warranty as of Feb 1st. They now want me to pay 4400 for a part that fails often. Is there anything I can do?

MVC involving 7 vehicles. My truck was rear ended, pushed into on coming traffic where i was hit in the front fender, bumper and side wall of front right side ( passenger side). The rear bumper was rolled under the truck and the front right side was pushed inward towards driver side. The front passenger seat was pushed toward the driver seat. NO AIRBAGS DEPLOYED!!!

My 2020 Silverado duramax was at the dealer for recall , next day check engine light came on and rear wheels got locked up , the dealer installed new transmission valve , next day same problem check engine light and rear wheels locked up again, now the dealer said is something to be with a speed sensor and I have to paid for it , my truck was perfectly working before all this recall thing, it’s been 3 weeks now with no transportation, because GM and Chevy dealer don’t want to respond or fix this problem with the transmission valve and transmission control module software that was installed My truck was all good before this matter

Component/system that failed: The transmission control module in my 2020 Chevrolet Silverado 1500 has malfunctioned. The vehicle has issues with slipping between gears, rough shifting, and hesitation when accelerating. This component has already been inspected and diagnosed by a certified Chevrolet dealership, and the part is currently on backorder. The vehicle is available for further inspection upon request. Safety risk: This issue poses a serious safety risk to myself and others. The gear slipping and delayed response when driving—especially when merging onto highways or changing lanes—creates unpredictable behavior that can lead to an accident. The truck sometimes fails to engage gears properly, which makes it dangerous in traffic situations. Diagnosis confirmation: Yes, the problem has been confirmed by a Chevy dealership service advisor (Jose Diaz), who provided a formal quote and diagnosis for the replacement of the transmission control module. Inspection by others: The vehicle has not been inspected by police or insurance representatives, but Chevrolet Customer Assistance is currently reviewing the case, and I was advised to submit this documentation. Warning lamps or symptoms: There were no warning lamps initially, Symptoms include slipping gears, hesitation when pressing the gas pedal, jerky shifting, and difficulty accelerating smoothly. These symptoms have progressively worsened over time. Additional context: I have learned that many 2020 Chevrolet Silverado trucks have been recalled for the exact same issue, but my VIN is currently not included. I believe this is a manufacturing defect and that my vehicle should be considered for inclusion in the recall or further investigation.

Before teuck engine collapse. Ww had concerns about truck sounded off. Misfire in engine, knocking noise. Truck shut down. Had it towed. GMC service department concluded that the 5th cylinder not firing properly. Lifters collapse. Fixed, it was costly $10, 100. Truck went back in shop next day mexhanic was busy. Waiting til after weekend to take truck back in. They had to physicallt look at why truck was vibrating. Engine light not showing issue. Neither did the code reader. Mechanic found provle to be the Torque convertor. Need to change that. Said it was a very common problem in Chevy trucks.

I began having difficulties with my transmission at around 75,000 miles. The transmission began to stutter and slip. The transmission felt like I was driving on rumble strips. Transmission was replaced after waiting approx. 4 months. The transmission was replaced with a new GM transmission at the dealership.

-Cylinder number 5 piston failure -Cylinder number 5 cylinder failure -Cylinder number 5 injector failure Vehicle was traveling at roughly 70 mph, everything operating normally. Suddenly check engine light came on, multiple traction control lights, cruise control disabled. Vehicle started to sputter and grey smoke showed out of the exhaust. Pulled over and shut vehicle off, checked oil and coolant level both were normal. Motor temp was slightly above normal. Restarted vehicle and it continued to sputter and smoke. Local shop ran codes that showed injector number 5 loss of signal. Upon further inspection a camera was sent down the number 5 cylinder, cylinder had excessive damage and metal fragments. Large amount of oil seen both on top of piston and on spark plug. It was determined that motor will need to be replaced.

Transmission stalls out when going from 1st to 2nd and when driving down the road in cruse control it shutters.

Front main bearing failure. I have 97,000 miles on my truck. I have the 6.2 engine in it. I see online that GM is having a lot of issues with this engine. My dealer is trying to help me deal with GM, but GM does not want to replace my engine. They want me to pay for it. This issue could have been bad if I was driving at highway speeds with my 2 young daughters in my vehicle with me. Definitely a safety issue.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, there was a ticking sound coming from the engine compartment. The contact stated that the sound later became an engine knock, and the vehicle stalled. The vehicle was towed to the local dealer, who diagnosed the vehicle and determined that the engine had failed and needed to be replaced. The vehicle was not repaired and was later towed back to the residence. The manufacturer was not yet contacted. The failure mileage was 75,718.

Vehicle Shudders between 35 to 60 mph consistent with torque converter / transmission issues.

Engine shut off while driving home from work on15 October 2024. Driving home while raining. Engine just stop and wouldn't start again.

From the time my vehicle had 30,000 miles on the engine, the engine light would come on and stay on with no apparent reason. I would take my car to my local Chevrolet dealer each time (by this time the light had gone out) and they could not find a problem. One technician told me that it sounded like a lifter problem that they were experiencing with these model vehicles. This happened approximately 8 to 10 times before the lifter failed. In January 2025, while driving on the Interstate Highway I experienced a sudden engine vibration and immediate 50% loss of power. Upon returning home, I took my truck to my local Chevrolet dealer where I purchased my vehicle. Upon inspection, I was told that it was apparent that a hydraulic lifter had failed. I left my vehicle at the dealership for the repair of the failed lifter which cost me $4,800. Two months later, I experienced the same problem with the engine, more violently vibrating. I again took my vehicle to the dealership and they confirmed another lifter had failed and took it in for repair under warranty from the prior lifter repair. I had again experienced more than 50% engine loss and had to get off of the interstate and travel on a side road because I could not maintain a speed over 45 to 50 mph. They repaired the same failed lifter bank that they had repaired the first time. Now, I am holding my breath, just waiting for the lifters on the other bank to fail for me to have to put in another $4,800-$5,000. I believe that this is an engine flaw that Chevrolet knows about. They have done nothing to fix this issue and have left it on the backs of the customer. Chevrolet needs to be accountable for these types of problems!

Transmission shutter

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at speeds slower than 35 MPH, while coming to a stop, the vehicle down shifted unexpectedly, causing the vehicle to come to a jolting stop. The vehicle was taken to a dealer where it was diagnosed and determined that the transmission fluid needed to be changed and the torque converter needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 50,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while the vehicle was parked inside the garage, he noticed a crack on the frame and there was water running back into the interior of the cabin and the backrest of the seat. There were no warning lights illuminated. On a separate occasion, the contact experienced water entering the cabin while it was raining due to the frame cracks. The contact contacted the water doctors and provided a diagnosis of frame crack in multiple locations, allowing water to enter the cabin of the vehicle and underneath the spoiler. The local dealer was contacted; however, the vehicle was not repaired because it was not under recall. The manufacturer was made aware of the failure. The failure mileage was approximately 40,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at approximately 15-20 MPH, the message “Engine Power Reduced” was displayed on the instrument panel, and the vehicle started shaking and decelerating. The vehicle was taken to the dealer who diagnosed that the engine wiring harness needed to be replaced. The dealer informed the contact that another part needed to be replaced; however, the contact was unable to recall the exact part. The vehicle was not repaired. The manufacturer was informed of the failure and informed the contact of a possible number for assistance. The manufacturer had opened a case regarding the failure. The failure mileage was approximately 124,000.

Engine misfiring multiple times over a period of 2 or 3 years. Took it to the dealership in Andrews Tx, could not duplicate misfire but saw over 600 misfires on a single cylinder, they said it was fuel pump failure. Replaced fuel pump. After a month misfiring started again. October of 2024 took it to dealership in San Angelo Tx, they were able to duplicate misfire, lifter failure. Replaced lifters and cam as it was beat up. One month after repair, vehicle started shuddering. Took it back to San Angelo service center, transmission issue, torque converter needs to be replaced. I refused the service as I would not spend $5,000 more after spending $10,000 to repair engine.

transmission make noise

The engine started making a strange sound while driving. Was taken to dealership were it was found that the engine was going bad due to a lifter failure. The engine only has 64,000. miles on it and was maintained by dealerships for routine service.

Transmission blew whole driving

When I would put the truck in park and proceed to turn it off, the computer would tell me the truck was not in park. I was told at the dealership that the transmission was in park, though the computer wasn't communicating correctly. Not only does it pose a risk of draining the battery, it is a safety issue. If I were to park on a hill, the only confirmation that my truck is in park is what's said on my dash.

When the truck was less than 2years and less than 20,000 miles old it developed a clunking noise in the rear suspension. Sounds like 2 heavy pieces of metal softly being knocked together. The dealership inspected it and replaced both rear shocks. The noise was still there. The dealership replaced the left leaf spring assembly. This temporarily eliminated the noise. The noise came back at just under 3 years and 30,000 miles. The dealership inspected, but couldn't find the source of the problem. The noise has only worsened since then, and at a recent visit to the dealership, they could clearly hear the problem. I was told that it is the result of worn cushions between the leaf springs. I'm concerned that the truck may be unsafe. I've been contacted by GM, and at this time they are looking into how to fix it, and who should be responsible for the repair. I can't imagine that mine is the only 2020 Silverado with this problem, and think there must be other reports of a similar nature.

Transmission is giving the same issues as the reported diesel transmission problems in same year model. Safety has not yet been put at risk. Due to a 2 month wait time I have been unable to get it inspected by a dealer.

Lifter failure in the motor ALso, leaking in back window

I purchased a 2020 Chevy Silverado 2.7 turbo RST from Greg young Chevy in Omaha Nebraska. Upon purchasing this vehicle within 20 days of ownership I got a check engine light indicating code P2090 for exhaust camshaft position sensor. The truck was taken back to the dealership and they at first tried to just clear the code and give the truck back however I put my foot down and requested them to look further into it. After weeks of them having the vehicle they determined there was an issue with the pcv oil separator and they replaced the part allegedly. After reviving the car back they strongly suggested I purchase an extended warranty telling me “you’re going to need it” we purchased the warranty only to discover the code reappearing less than 2,000 miles later and a tic sound in the engine. My independent research has concluded it’s a lifter failure and those lifters are now slamming into my camshaft causing excessive damage. After getting the code read more in depth I can confirm they again just cleared the code and an oil leak is still existent in the engine. This causes the auto stop to disengage which makes the vehicle leech forward when at rest while my foot is still present on the brake as the camshaft does a full rotation to adjust and correct itself to the sensors suggested position. On average this moves the vehicle approximately 1 foot forward and could lead to me damaging my vehicle or causing harm to people in crosswalks.

My 2020 Chevrolet Silverado rear window leaks causing mold on headliner and carpeting and if running electric defrost during rain it makes a sizzling noise afraid of electrical issues as well if not correct and the mold makes the interior environment unsafe for breathing

6.2L V8 had catastrophic failure due to lifters failing while driving at highway speeds.

The Transmission is skipping gearing. There has been a recall for 2020 Chevrolet 1500 Silverado, but my vehicle has not been call.

My break system failed twice in 2 weeks. On Feb 01, 2025 around 5:35 pm, I almost ran over a dog the first time because I lost access to breaks and emergency breaks and could not stop going through my neighborhood. Today on Feb 13, 2025, I had picked my son up from school, and the breaks went out after we left the school. This time I almost ran into a car but had to turn off to the right to avoid hitting it. My son and I could have injured the person driving in front of us and ourselves. I looked up the problem, and it seems that many others have faced the same problem. When I turned off the truck for 10 minutes, the system would reset itself and start working normally again. I took the truck to the shop, and it is currently there so they can run tests on it. I recorded what it looks like on the dash when I lose all braking.

Hard shifting and shuddering

The engine is blown. Our GM Dealership where we purchased it, inspected it and says the engine cannot be repaired and must be replaced. And independent garage gave the same diagnosis. Went from running fine one day , to bucking and stalling in traffic causing a hazard to everyone on the road. Check engine light, check brakes, stabilitrak, ALL the lights on the dash were on like a Christmas tree. It doesn't run now. Currently sitting in our driveway now unable to be driven for three months as we don't have $10,000.00 for a new engine, and the extended warranty we purchased through the dealership expired 4 months before it blew up. We are now making loan payments on a GM vehicle that did not even last the length of the loan. Seeing a report on this exact issue, we did not even know until today that there was a place we could send in a complaint to. You are welcome to inspect the truck, but you would need to come to us, as it cannot be driven. Where can we get any help with this? Please help.

After driving and doing errands I tried to pull truck into garage and noticed it was hard to move. It seemed like brakes were stuck on despite not applying brakes. I pulled out of driveway to drive around block. Lost all brakes while driving down county road at 50 mph. Check engine light on, brake failure warning on, warning light that speed limited to 43 mph, ABS light on. Eventually able to stop. Turned off engine for a few minutes. Restarted and brakes all worked again although check engine light still on. This could have been deadly on a steep road or on ice or in traffic. I see online that this is a common problem with Chevy trucks although no recall has been issued for this one. I am very concerned that this truck is not safe - for me or anyone else on the road with me. I have not taken it in. I live in the country, some distance from a dealership so nothing has been confirmed. Nothing like this has happened to this truck before and there was no other warning. It is available for inspection but is my only transportation.

Vehicle started miss firing along the highway without any previous signs of problems. The vehicle was driven straight to our home and then to the dealership a few days later. We were told there, the lifters have failed. Once they started the repairs we were also adviced the cam have suffered significant damaged and needed replacement as well. The vehicle was only inspected at the dealership once it was dropped off. The first and only sympton of the insurance was the day it failed.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while the vehicle was parked, there was an abnormal sound coming from the engine compartment. The check engine warning light was illuminated. The vehicle was taken back to the residence. The contact used a diagnostic tool to determine that the vapor canister purge pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 41,000.

On January 17, 2025, I was approaching the entrance ramp unto Interstate 10, traveling along at approximately 40 miles an hour, when all of a sudden I noticed that my vehicle started decelerating as I was pressing on the accelerator, trying to merge onto oncoming traffic. The engine started shuttering and vibrating violently! I noticed all the warning lights, gauges and indicators had come on simultaneously! There was a loud clicking sound coming from the engine compartment and backfiring coming from the exhaust. I evaluate the situation at hand and conduct a risk assessment of trying to continue on with this problem but decided to move over to the median. I was almost run into from the rear due to lack of power in which I felt would have been the result of my truck just losing power without any warning. I drove my truck to a Chevrolet dealership after speaking with a Service Advisor, on January 20, 2025. The Truck was diagnosed as needing to replace Cam Rod and Lifters.

At roughly 146,590~ miles the truck began making a knocking noise while driving at any speed, complainant had the truck towed to independent shop and was evaluated. Was told by shop that the engine can shaft pitted and engine metal shards had exploded and shattered throughout the engine. Making the opportunity for engine stalling or risk of fire/ smoking while operating the vehicle extremely likely. Complainant was told there was no access to engine replacements or parts at this time and the wait time to receive one was 4-6 months. No warning lights ever went off. Engine was eventually replaced entirely when the part became available by an independent service dealer.

Rear sliding window is leaking from unknown area.

In November 2023 my check engine light suddenly started flashing, my service parking brake light came on, traction control light came on and service ESC message was on the DIC. Then my truck started running really rough. At the time I was going roughly 10 mph. I took it to the dealership and they found a lifter had failed. My truck was at the dealership for a month. Fast forward to now, February 2025 and today I got the exact same lights appear on my cluster and same message. I was driving approximately 50 mph and my truck felt like there was a lack of power and there was hesitation in the engine.

Check engine light came on at 100,000 and was told I need new engine from John Miles Chevrolet

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 80 MPH, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was towed to the dealer where it was diagnosed and determined that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 120,000.

The engine blew a rod through the engine block and dealership replaced engine June 2023. January 2025 engine abruptly stopped while on the highway at 70 mph and now waiting on diagnostic test from dealership but after reading all the incidents regarding this engine I feel it’s another L87 engine failure from GM

This morning it was 16 degrees F I drove about 6 city miles at about 35 mph. I was 1.5 miles from home when leaving a stop light the truck bogged down and was only going up to about 25 mph with the tach at 2000 rpm. It seemed at first that I was driving with the parking brake on but most V8's have enough power to override the parking brake. This acted as if I was pressing hard on the foot brake while driving and giving it a lot of gas. I probably would have had to floor it to go any faster. But was afraid of damaging something. Put on the flashers and drove about 15 mph with the tach at 1500-2000rpm. The dash displayed "Brake system failure 62 mph top speed", "Service ESC", "Parking brake failure" and "Service trailer brake system", The brake pedal was changing its height by itself. Pulled to side of road and pumped the brakes several times, shifted the transmission through park, neutral, reverse and drive and it seemed to operate normally. Pulled onto road and it was bogging down the same. Pulled to side of road again. Then started driving again with flashers on and the tranny shifted as normal, but the brake pedal went to the floor. Pumped the brake pedal and it still went to the floor. Drove slowly while checking the brake occasionally but still went to the floor during the 5 blocks to my driveway. The brake had no effect. My driveway slopes slightly upward so I stopped safely. All four wheel centers and brake rotors were too hot to touch after slowly driving the 1.5 miles this occurred over. About 15 minutes later I turned on the key and the dash displayed "Brake system failure 43 mph top speed", "Service ESC", and "Service trailer brake system". Fortunately there were no vehicles close in front of me when this started and many were behind me when driving with my flashers on due to quite a bit of traffic. This could have been a disaster had it occurred somewhere else. The local Chevrolet dealer that services it has not seen it yet.

significant loss of power due to engine failure related to DDI while driving.

Transmission shudders and has a delay in shifting/starting movement of the vehicle. This problem was noticed at 98k miles about a thousand miles after I purchased the truck from a dealership. It has been inspected, and repairs scheduled, but the transmission is still on back order after 5 months of waiting. No part ETA is available from Chevrolet corporate. This issue is a safety concern due to the fact that the vehicle could hesitate to accelerate in the event of needing to take evasive maneuvers to avoid an accident/road hazard.

Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates.

We were driving on the highway when we attempted to make a turn the Steering wheel would not turn. We almost had an accident. I, [XXX], the Driver, had to swing out, and force the steering wheel to turn to get out of traffic. The service steering system with care light and the ESC Light came on. My truck is not that old and should not experiencing this type of problem. This was a very frightening experience that I don't want to go through this anymore. I call the dealership that I purchased the truck from and learned that other models had a recall on the same issue, but my 2020 had no recall on it. So therefore, they did not have to work it in to fix it. So, I'm reporting the issue so that no one else have to experience what I did.

I bought this truck with 72,000 miles on it I put about 3,000 miles on it and the engine seized. I had my mechanic inspect it and he confirmed the motor is seized. There was absolutely no warning is just stopped running and left me on the side of the road

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle briefly hesitated and experienced hard shifting before returning to normal functionality. The vehicle had returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V797000 (Power Train); but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 60,000.

Vehicle has been in and out of service for the past 5 months with multiple alerts including "Brake system failure 43mph top speed," "service esc," "service brake assist." On major interstate car would not accelerate past 43mph putting myself, infant, toddler, and wife in danger. Multiple attempts have been made to repair the vehicle and nothing has been successful. Lifters, CAM, torque converter, EBCM, master cylinder, calipers, and the list goes on. When this happens the brake is extremely hard to press making it difficult to stop the vehicle. Issue has been reproduced by dealer and attempts have been made under warranty to repair. Car only has 36k miles on it and the issue began prior to that. GM ongoing solution is to bleed the brakes, which clearly has not resolved the issue. Still hear ticking and noises from engine. Something needs to be done to remedy this issue. This is a safety hazard for myself, my family, and everyone driving around me.

Upon entering a roadway from a parking lot I noticed my vehicle struggling to gain speed. I lifted my foot from the gas pedal and the truck rapidly reduced speed, dropping from 25 mph to less than 5mph in a couple of seconds. I then reapplied the gas pedal to attemp to avoid the vehicle approaching from the rear. The truck struggled again to gain speed. I went about 150 yards toward an intersection. I applied the brake and pushed it to the floor as the truck barely slowed to a stop. Had there been any vehicle stopped in front of me I would have hit it and pushed it into the intersection. The dashboard lit up with warning lights and rotating messages such as, Brake system failure 62 mph top speed, Service trailer break.when the traffic light turned green I drove it across the intersection into a parking lot, going about 5 mph for 50 yards. Putting my foot back on the brake as hard as I could. It finally came to a stop about twenty feet farther than it should have. I had it towed to a Chevrolet dealership. They did a diagnostic test and checked all braking components. They found a service bulletin for recalibration of brake system control module. They preformed the calibration and cleared the codes. After reading the many reports of this happening on the NHTSA site and the absolute possibility of injuries and deaths, I find it hard to believe that with knowing this problem exists and it’s disastrous potential, that there has not been a recall after 5 years of complaints.

While driving home truck began to misfire and drop in RPM’s. Service ESC and Service Parking Brake popped up on my notification system. My Engine light was blinking and my Traction light was on. While i was turning into my street to get home, my engine shut off. The steering wheel and brakes became hard as the motor wasn't powering them. I was able to turn it on and get it into my drive way. Afterwards when trying to turn it on, it would turn on and shut off immediately. Chevy replaces a fuel pump module for a second time(recall), added a new starter and battery. After Three months they then told me I need a new engine because it has locked itself up. I purchased the vehicle with 32,000 miles and It currently has 49,000 miles. Chevrolet are not going to warranty me a new engine because i do my own oil changes (which were 2). Had this happened on the highway or in traffic, i would've been at a high risk of causing an accident considering power steering and brake system was not working properly.

Truck has been burning oil since it was purchased new in 2020. The truck has needed 6 quarts added between every oil change. It has been to the dealer and they insist nothing is wrong. GM customer service has been no help. Motor has a ticking noise. Finally 2 weeks ago check engine lights came on and loud noises came from motor. Brought it into the dealership and they said full lifter failure and engine scoring and has been like this for awhile now. This is something I brought up to them AND GM support over the last 4 years of owning the vehicle and they always told me there was nothing wrong with it. Private extended warranty is going to cover a new engine, but is on national backorder due to all the issues with the 6.2L engine and others having issues GM won’t acknowledge.

Vehicle would not start, had it towed to a shop and they said the engine locked up. After tearing motor down the main bearing was scored and there were metal scratches.

Upper control arm ball joint separated.

I was driving on a wet Road with more than an inch of water on the road and all of a sudden my engine blew up I took it to the Chevrolet dealer and they told me that water got in the engine and it was my fault I feel that the engine failed and should not have

Excessive Oil consumption from new and lifter failure at 116,000 miles

Had the top of the motor rebuilt twice, first the left side, then the right side. Then GM replaced the motor out of warranty. A year and a half later the rear main seal blew and the seal was all mushroomed and out of shape.

While driving down road at around 60mph 6.2L engine started to make loud knocking noise and shaking violently while loosing all power. Truck had 79,797 miles on it at the time with all oil changes and service done at GM dealership. After having GM dealership diagnose truck, it was determined to have a spun rod bearing, causing multiple other engine components to fail. Truck was not under factory warranty and was quoted $12,200 to replace. There were no warning lights or any known issues until this incident.

Purchased not thinking there would be issues as truck was clean and well kept. Month and a half later torque converter went bad. Had it replaced under warranty, however, I have more symptoms from when it originally started. 6 speed transmission.

While changing a blown fuse for the instrument cluster, my truck unexpectedly caught fire, endangering my safety and causing significant damage to the vehicle. The fire started behind the passengers side fuse box within the wiring harness (GM# 84717166). The dealership determined that the failure was due to wire harness chafing on the thread side of a tie bar bolt. Due to General Motors not responding to their request for repair information via the TAC, they concluded that the bolt needed to be shorten in order to reduce the chafing. There were no warning signs or indications that this was going to or could occur. The burnt harness is available for inspection but the vehicle has been traded in due to no longer trusting how it was manufactured.

Purchased a 2020 Silverado 1500, 5.3L 4x4 with 8,000 miles. Now at 66,000 miles the torque converter is bad. Shudders, hard shifting, lunges into gear, won’t go into reverse at times. MULTIPLE complaints with these engines. There’s a recall, but it stops at 2019….. WAKE UP GM!! This problem is still ongoing from 2020-2024!!! Needs to be another recall

Transmission shuttering when driving

Rear window leaks water into the cab during rain, snow, car wash, etc. GM refuses to abide by comprehensive warranty to fix the issue, and my dealership wants to charge around $1,000 just to apply sealant. Water goes into and behind the rear seat (where my child sits) and goes to unknown area. Water can cause rust, mold, electrical problems, or any other number of issues. I noticed it around November of 2024 but I don’t know how long it has actually been occurring for. When researching this issue, appears to be relatively commonplace for my year and style of vehicle. Even the GM techs at my dealership acknowledged it is a recurring issue that may require MULTIPLE visits before getting a permanent solution (replacing the entire window).

While driving down the highway, the ball joints on the front passenger side prematurely failed, causing loss of vehicle control, significant damage to steering and braking components and body damage. Diagnosis is being confirmed by an independent service center. No symptoms of premature wear or imminent failure were noted.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds in inclement weather including while driving in rain or slushy snow, the tailgate inadvertently opened. The vehicle was taken to a dealer where it was diagnosed and determined that the tailgate switch needed to be replaced due to water intrusion. The manufacturer was notified of the failure. The failure mileage was approximately 14,000.

The rear wheels lock and most of the time its hard shifting/ or it feels like it struggling to shift to the next gear

First incident was when the vehicle had under 7,000 miles. Transmission module went. Vehicle wouldn't move. A few months prior, when we pulled our camping trailer, the integrated brake didn't work and the truck brakes overheated. Took vehicle to dealer, couldn't find a problem. A few months later the truck would not move, and found to be the transmission module. After a month and they finally got the part and repaired, no problems with pulling the camper. Than last week, we pulled out on the road, and we couldn't accelerate. A little over 45,000 miles on it. Had towed to dealer, they have diagnosed Transmission Valve Body. No warning lights. Maybe the transmission was hesitating some before it went. Waiting for the part, which no clue how long it will take.

2020 Chevy Silverado 1500 8L90 transmission failure at 40,000 miles and I am now at 90,000 miles with the same issue. I have been working on this truck tirelessly tried to fix the transmission. I’ve had 3 transmission fluid replacements and a full torque converter replacement. General Motors knowingly sold these models to consumers when the transmission was faulty and underperforming. It shudders, shakes, and slips while driving. It’s almost caused me to get into a few accidents. I just want compensation and to be a part of the class action lawsuit they are being filed upon.

about a month ago, began with a shutter or studder at low speeds. Became worse and a vibration on the interstate as it sounded like i was driving over rough ground. have now seen two mechanics in person and talked to another on the phone and all are saying the torque converter needs to be replaced. the check engine light has not come on which is also a concern as this is a major issue. safety concern is getting on the interstate into traffic and difficulty accelerating. experienced a lockup and swerve when accelerating up a hill which is very scary as my children were in the car. this is a 2020 silverado 1500 purchased new from dealership with 105k miles

My vehicle has an incomplete recall, I am not getting what I paid for, still under warranty, not living up to GM Chevrolet warranty. Doesn't feel safe to drive.

Driving at the speed limit 65-70 miles ph my truck started to slow in speed the tire sensor came on then the truck began to smoke and the brakes locked up at a high speed, lucky for me there was no one behind me. I was able to limp to a safe spot and park the truck would not MOVE at all..After an hour I tried to move it again it would not go into drive. Had to tow it to the dealership..$$$$ later they say well we can't recreate the problem so it's drivable. I drive 2 blocks and it stops in traffic almost causing a collision. Had it towed home and for 3 moths now it has sat while I have to continue paying payments on a NON running 2020 with only 102 thousand miles on it this is CRIMINAL!!!!!!!!!!!!!!!!!!!!! was told possible $62k to repair but no guarantee it would stay fixed!!!!!!!!!! Criminal and should not be on me I am paying still. But if something is not done I will let it get repo..I am [XXX] old this was to be my last newer vehicle I have had to borrow money again and bought an older 03 silverado that is running great.

The contact owns a 2020 Chevrolet Silverado. The contact stated that while driving at an undisclosed speed, he heard an abnormal sound emanating from the rear end suspension. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that fuel leak from the fuel delivery system resulted corrosion of the left side leaf spring grummet. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 30,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while the vehicle was parked, the brake pad sensor warning light illuminated. The vehicle was taken to a dealer to be diagnosed; however, the vehicle was not yet diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 32,000.

The specific issue that is being recalled is malfunctioning on my vehicle. I have taken to the dealership but they won’t help because the solution hasn’t been identified. My truck has suffered repeated failures resulting in excessive wear and tear on the transmission. I’m afraid a catastrophic failure will occur if I have to keep driving, without a solution. The dealer simply cleared the code. They should replace the part that is failing at a minimum. Even if it might happen again down the road. They will have a solution by then.

Dealership attempting to sell a vehicle with an open recall was more than prepared to let me drive and potentially sell a vehicle with a recall open causing the rear tires to randomly lock up. Made problem known to salesman and said they'd take it off the market. Now, they lowered the price by $2600 as it was previously listed at $25,571, now listed at $22,971. Listing still not down.

This vehicle, only 4 years old, experienced lifter/engine failure during normal operation, which required unsafe driving conditions and a roadside emergency. The vehicle was towed to the service location, where a complete engine disassembly took place, and required a 3 week repair period. The truck experienced a rough idle/shudder at a stoplight, then proceeded to show a flashing check engine light (P0305), a service emergency brake warning, and a service traction control warning.

While driving, the vehicle began experiencing hard shifting. When I attempted to accelerate to pull over, the vehicle failed to respond and instead sounded as though it was in neutral. Additionally, when I tried to bring the vehicle to a stop, it took longer than usual, as if the wheels were locked.

Brake system lights on dash came on as well as the check engine light. Park light was flashing on the dash. Safety is at risk as parking brake does not work. Took vehicle to dealer and they ran diagnostics. Codes: c0610 05, c0616 5a as per document id: 5709204. They said I need a new Brake System Control Module. Brake System Control Modules are on backorder. Brake System Control Modules have been recalled on Silverados in the past. I'm worried that this is unsafe

My vehicle only has 20k miles on it and I’m already replacing a lifter and camshaft due to the active fuel management system. At the time of taking my truck in there are three other trucks for the same issue. This is known issue at my dealership and this time I’m covered under warranty, but they told me to be prepared to repair this again and next time will be out of warranty and around 5k to repair.

Engine light came on, service park brake light came on, truck started jumping and misfiring, code says cylinder 5 misfire.

Brake failure. I took the Truck to the dealer and was told not to drive it. The dealer ran two checks and then said brake failure. The rep had to leave, so another rep put my car in the shop overnight. The next day, I was told in writing that they could not find any problem. The code clearly showed brake failure. Date: [XXX]. Cost: $125.69. Mileage was 53,531. On [XXX], another brake failure. I went to an auto parts dealer (O Riley) in Topeka, KS, and they found a brake failure code(I have a copy). They told me to go to the dealer. I went to the dealer with a stiff pedal, which means driving is very unsafe. The dealer said too busy with oil changes and told me to return another day. I said no breaks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2020 Chevy truck falls under the recall out right now. I drive my family around in it and feel a bit unsafe. How long does General motors have a remedy for this recall? And what are the next steps if a remedy isn’t made in the timeframe allowed? I’ve contacted General Motors and cannot get an answer. Thanks

The contact owns a 2020 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 24V797000 (Power Train); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated while driving 70 MPH, the rear end locked-up, and the check engine warning light immediately illuminated. The vehicle went into LIMP Mode and failed to exceed 50 MPH. The failure had occurred three times. The dealer was contacted. The manufacturer was made aware of the failure. The failure mileage was approximately 128,000. VIN tool confirms parts not available.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds or at a complete stop, the vehicle jerked while depressing the accelerator pedal with the check engine warning light illuminated. The vehicle was taken to several dealers where the spark plugs, engine wiring, and other various parts were replaced; however, the failure persisted. Upon investigation, the contact discovered NHTSA Campaign Number: 24V797000 (Power Train); however, the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 87,500.

The truck is only three years old with 123,000 miles and the transmission needs to be replaced. I took the truck to Chevy and they said the transmission is bad and they need to replace it. GM and Chevy will NOT cover the cost to replace the transmission or help with any cost. This truck is fairly new and it's a lot that the transmission is already bad. Chevy quoted me $7,990 for new transmission with install.

The 10 speed transmission suddenly downshifts when slowing down. It goes from like 8th to like 3rd suddenly and the rpm’s shoot way up. The wheels do not skid on pavement but will be an issue when the roads get slick here in West Virginia. This is a serious safety concern. This has happened many times since I purchased the truck. The dealer in the past has told me the transmission needs flushed. But now I’m seeing that there is a recall for new transmission software. I would like to have this update please before the roads get slick from snow and ice.

The back window is leaking water into the cab. Water enters the cab any time it rains or when washing the truck. This water is creating a damp environment by soaking into the back of the seat, the carpet, and the headliner, creating the potential for black mold. Immediately after purchasing the truck, the dealership had me bring it back in so they could fix it. Ever since the repair from the dealership, the window has continued to leak at the same rate that it did before the fix.

Transmission continues to lock up while driving

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle shuddered abnormally. There was no warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed or repaired. The vehicle was taken to the dealer where it was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 97,000.

I have already sent in one complaint about my vehicle and a recall came out but my vehicle isn't on the list and I know there is something wrong. My steering wheel will lock while driving my transmission sticks sometimes I can steering because my steering wheel acts as if it does not work. I have had horrible vibration since day one I have to get an alignment 2 to 3 times a year

Shifting problems. Transmission feels like it is going to fall out. I have taken it in several times to be fixed and my Chevy dealer can not figure it out. Problem never fixed.

Rear sliding plastic window frame cracks and allows water to seep into the cab. Hardware and metal brackets have rusted, electrical components may be at risk of shorting out. Mold and mildew can be smelled on warm days, which poses a health risk. Complete window has been replaced twice and original and replacements have all been resealed as a "repair" but has failed on all attempts. Headliner has been replaced once and is currently stained again due to another leak. No updated GM part exists to remedy the known issues.

On September 21, 2024 my Chevy 1500 series truck in the year was 2020. It was made caught on fire white driving it. We were returning from a trip pulling a trailer from Kentucky to Mansfield Ohio when we were on the highway. The transmission light/panel came across and said transmission need to engine idle. I drove it about 3 miles and pulled off on an exit at a gas station and did what it said after proximately 10 minutes. The message went off and cleared. we resume going home on our trip and we are 14 miles on the highway then we got off on our exit there’s no lights or no problems with the vehicle. I dropped off the first passenger and Lexington, Ohio, and then the second passenger lived about a half mile away , this time kept unloading their equipment. From Lexington to my home in Mansfield, Ohio the other passenger I was talking about the light transmission was weird and might’ve been just a sensor. As we pulled onto Home road all the panel lights started flashing and then a message came across and said engine is shutting down. I put in park off the engine, we exit the vehicle and smoke was coming out from underneath the truck. I reached into the center council to grab the cell phones and had faster call 911 and when I reached back into the truck were coming out from underneath the hood. I notified General Motors on September 23 and have been battling them to get an inspection done. after several months, they have finally agreed with insurance company on terms to investigate what caused the fire. That inspection is to Take Pl., December 4, 2024. I have recently just seen the recall article on GMC that came out on November 13. My truck is listed in the article as far as your make and model. This was a transmission problem that GM is trying to ignore and should be held accountable. Have video of when it caught on fire and how quickly it burned up.

My truck has 75K miles and the transmission has a shudder and it shifts very hard. I have been told I need a new transmission by an AAMCO shop which will cost just under $7k. This is ridiculous for a 2020 pickup.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed and driving over a speed bump, the contact noticed that the power steering became inoperable with the Electronic Stability control warning light illuminated and the message that the “Power Steering was Disabled” was displayed. The contact stated the vehicle became difficult to steer. The vehicle was restarted; however, the failure recurred. The vehicle was taken to the dealer where it was diagnosed with power steering control module (PSCM) failure. The contact was informed that the PSCM needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 53,000.

Engine start to make noise while driving Took my truck to a auto shop Mechanic said that it is a fabric defective engine

ESC error code come on with a traction control off symbol and the drive Steering Assist Reduced Drive with care. I lost my power steering out of now here when driving on roads that are not very smooth or if I turn my wheel all the way to one side. I was able to muscle the truck home safely.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at 55 MPH, she noticed in the rearview mirror that her steel chainsaw was hanging from the vehicle and pulled over to the right side of the road. Once outside the vehicle, she noticed the tailgate opened independently. The vehicle was not diagnosed or repaired. The VIN was not included in NHTSA Campaign Number: 24V060000 (LATCHES/LOCKS/LINKAGES). The manufacturer was not notified of the failure. The failure mileage was 59,000.

We went to an appointment and when we got back in the car, a message was on the screen. It said that the brake system has failed and we could only drive 43 mph maximum! The engine light was on and we could not accelerate beyond 43 mph. This is extremely dangerous when driving on a highway! We drove home on the interstate going 43 mph in a 70 mph zone! We had small children in the car and almost got into a few accidents due to other aggressive drivers. We then called local dealers who said that they were too busy to take our truck for weeks! They also said that our truck was not covered under warranty. So we took it to a local body shop. They fixed it for just above $500. It worked for a week and broke again, then they fixed it again for free. The brake failure 43 mph light came on for the 3rd time. We took it Garber and they fixed it after 2 weeks and charged us a fortune. Invoice attached. A few weeks later the same light came back on. Garber then took another 2 weeks to fix it! I’m writing here as I’ve seen other silverados recalled for the same issue but not my exact truck (year). It’s obviously faulty software and it should not be the customers responsibility to fix. Especially with a vehicle under 20k miles! There is absolutely no way that we will ever buy a GM again but the important part here is that other people are not put into a dangerous situation like we were. Besides dealing with this issue for well over a month - the important part is safety. I can’t understand how these trucks have the same problems but only certain VINs qualify for a recall. Please consider our truck as part of the overall recall for this issue. It’s unethical to pick and choose only certain VINs!

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while activating the rear window defroster, there was a crackling and sizzling electrical sound coming from the lower section of the windshield were the electrical components were located. The cause of the failure was not yet determined. The manufacturer and local dealer were contacted but no assistance was offered. The failure mileage was 49,000.

I'm not sure what to call most of this but my truck has been vibrating when getting up to about 50 mph. When putting in gear it shows you put it in the gear wanted put doesn't register sometimes and perks you and clicks. The entire front end grinds,pops and clicks when turning forward or backwards. When doing the steering wheel will get stuck and want turn for a split second in turn causing steering To be misaligned causing you to basically steer the wheel in an unnatural position until you stop put it in park then proceed to drive again. I have had these issues since we bought the vehicle brand new. We have to get an alignment and balance rotation like every 6 months for it to only help for a about a month to not be as bad.

The truck caught on fire while I was returning from a trip out of state and then it appears it came from underneath either the transmission the engine or electrical. While returning home a message came on the panel on the highway, saying transmission, hot idle run I pulled off and did this and after about 15 minutes, the message light went off and I pursued Coming home nothing was wrong with the truck. After I dropped off to the passengers, I was on the way home and turned on home road and the message came on that says truck powering down all the lights came on the dashboard. I put the truck in park and shut the engine off had a manly open the doors and got out and smoke was rolling from underneath the truck. I grabbed the cell phones and told my passenger to call 911. I went back into the center of the cab to grab something out of the center council and flames came from underneath the hood up the glass of the windshield right in the middle of the truck. Backed away I called 911 again. Troy fire department responded in about six minutes. The truck was engulfed and gone. Ohio state patrol give me a claim number of [XXX] the instant [XXX]. There has been no problem with the truck or vehicle during the time I owned it. It was regularly service. It had 109667 miles on it. The truck was a 2020 Silverado from Bill Harris Ashland.

Rear end went out within drivetrain warranty period. Chevy claimed it was due to a leak even though there was no evidence of one and they couldn’t produce the part. Almost immediately after getting it back it started to have transmission problems (8L90). They again claimed there wasn’t a problem. The truck now has 120,000 miles on it and we are replacing the transmission after it would drop gears and, finally, wouldn’t go into reverse.

I was driving the vehicle but it sounded like it was popping when I would turn and when I shifted gears. As a result, my brakes were not working and I almost hit another vehicle. I took it to the dealership where they claimed they fixed the issue. When I picked it up this past Saturday, within a block of the dealership, the truck began shaking and a rattling noise could be heard. I had to take the truck back to the dealership. The truck is at the dealership where it is supposed to be inspected again and hopefully properly fixed.

While the vehicle was in operation, the drivers side mirror fell off. The is a safety risk as I was not able to use mirror to check for vehicles in blind spot or in left lane as I was driving. Not to mention, as per NYS vehicle and traffic law, vehicles have to have at least a drivers side rear view mirror while in operation. After the vehicle was parked, inspection of the mirror assembly found severely corroded swivel and corrosion on the bolts holding mirror on the truck.

While driving on the freeway the right control arm broke.

The Electronic Steering assist stopped working while I was driving to work. Was leaving a stop sign and steering wheel became stuff and notifications on dash appeared. Was able to get to side of the road and turned vehicle off for 20-30 mins and started back up and steering was normal. Notifications on the dash were: Service Power Steering and Service Trailer Braking System. Search online showed this is a known issue that has happened with these vehicles for years and clearly hasnt been addressed. This is very dangerous. Vehicle has 42k miles on it. I had the "Service Trailer Braking System" notification come on a couple times previously and steering felt "sloppy" but immediately went away. And Ive never used the trailer braking system so I didnt think anything of it.

I'm beginning to have similar problems with the 6.2 ecotec3 engine that gm has known problems and hasn't recalled them. Dealer indicates metal shavings from the main motor bearings. Just like others I will experience a total motor failure at anytime. This will be catastrophic if motor fails and shuts down. I fear I will be rear-ended or not be able to get out of harms way. This has happened to many with the same motor. Why would there not be a safety recall on a known safety issue. Others affected have been injured even killed because there vehicle just stopped in the middle of a roadway. I currently fear for my families safety and cannot simply opt out of a vehicle with only 18,000 and thousands invested. Instead it sits waiting for the right thing to be done. To be repaired to safely use. Thank you kindly.

2020 Chevrolet Silverado 1500 Custom, bought new on August 10, 2020. On August 24, 2020 I returned the vehicle to the dealership with 524 miles on the odometer, for hard downshifting at low speeds. The technician returned the truck with 531 miles, stating that he could not duplicate the issue. The issue continued along with occasional shudder at speeds around 40-50 m.p.h. On December 14, 2022 I took the truck to a different dealership with 1,616 miles and it was returned with 1,625 miles on the odometer. The technician found a slight shudder at 25-30 m.p.h. under light acceleration, but could not duplicate any other malfunction. The technician stated there was no metal debris in the fluid pan and performed a flush and refill of transmission fluid, installed updated thermal bypass valve and three seals. The issues still persisted, but not as harsh or as frequently prior to this service. I returned to the original dealership again on September 3, 2020 with the same concerns at approximately 28-K miles. Again, after having my truck (4) days, the original dealership's technician stated that he could not duplicate the problem(s).

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds, the contact experienced resistance while using the gear shift lever to drive and there was a hesitation while shifting gear. Additionally, while in reverse on several occasions, the back over prevention screen went black and failed to operate as intended. The vehicle was taken to a dealer but was not yet diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 20,000.

Truck was purchased from an authorized chevy dealership less than 6 months ago. Truck had transmission service just before purchasing it as it was *maintenance* not repairs. However all of a sudden the truck will stop accelerating in the middle of intersections where you typically would have a 1-2 or 2-3 shift. along with during acceleration on highway it will decide it doesnt want to shift anymore to a higher gear than 4th or 5th. This is causing a constant safety threat as i cannot control when the vehicle will move under its own power. This is a known problem with cheverolet as they will replace the parts that cause this if its under warranty however mine is not. Although the warranty is up the issue is caused by poor manufacturing process and they know that.

While driving 55+mph on a parkway the service parking brake, check engine light and the traction control light came on with a warning "Engine Power Reduced" which was dangerous because I could not accelerate and there was not a spot to pull over. This is frustrating due to the fact that I was having this same issue 6 months ago and Chevrolet said it was a wiring issue and it wasn't covered by the warranty because it had 42k miles. Chevrolet said it was a known issue but it was not at the level of a recall and it cost $1800 to fix.

“Service power steering soon” message appeared and I took it to a Chevrolet dealership and I was informed I needed to replace the power steering module for a total of $2300 for parts a labor. Now the power steering will randomly stop, making it almost impossible to drive. There are hundreds of threads online of this model having the same issue and this should be a recall because someone is going to get injured.

THERE IS A KNOWN ISSUE WITH KNOWN LEAKS AT THE REAR SPOILER/ 3RD. BRAKE LIGHT. DUE TO THIS LEAK, THERE IS AN ODOR IN THE VEHICLE CAUSED BY MOLD OR MILDEW WHICH IS CREATING BREATHING AND ALERGY ISSUES. I RECENTLY HAD OPEN HEART SURGURY AND THIS IS STARTING TO EFFECT ME TO THE POINT I CAN NOT BE IN MY VEHICLE WITHOUT THE WINDOWS ROLLED ALL THE WAY DOWN. AND I GO INTO SNEEZING FITS WICH IS A SAFETY CONCERN

Our 2020 Chevy 1500 Trail Boss was waiting for an ordered instrument cluster at service department. The surveillance camera, film the vehicle catch on fire after being parked for 2 days. The smoke started from the inside, and the vehicle engulfed in flames until the fire department came. After the fire was extinguished very little was left of the vehicle. Basically a frame and engine was the only thing left. The vehicle had a little over 70k miles.

SERVICE POWER STERING AND SERVICE ESC WARNING LIGHTS CAME ON, LOST POWER STERRING. AFTER 30 MINUTES RESTRATED THE TRUCK AND EVERYTHING WAS FINE. TOOK TO CHEVEROLET DEALER, THEY FOUND NO CODES AND COULD NOT DUPLICATE THE ISSUE, HAD NO SOLUTION FOR HELP, TOLD TO BRING BACK WHILE ITS DOING IT, YOU CAN NOT DRIVE IN THAT CONDITION. VEHICLE HAD 16,880.00 MILES ON IT WHEN PROBLEM OCCCURED,

While driving hauling trailer, tailgate randomly flew down, could have been very very bad had someone been behind me when wheel barrow flew out of the back. It severely damaged my tailgate when it flew down, and then got wedged between top of trailor.

Total engine replacement at 62k. The junk lifter system government regulation has compromised our Vehicles. Active fuel management systems are used expensive trash changes to our American motors that generate extreme hardship for single vehicle owners.

Vehicle is burning oil. I drove 300 miles and had a low oil message pop up. Vehicle still had 50% oil life left.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving approximately 35 MPH, there was an abnormal sound from the engine compartment. The contact stated that the check engine warning light was illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the serpentine belt needed to be replaced. The vehicle was repaired. The contact stated that the failure recurred, and the vehicle was taken back to the same dealer and was repaired. The contact was concerned that the serpentine belt had failed twice. The manufacturer was informed of the failure. The failure mileage was approximately 3,500.

Power steering stopped working while making a left hand turn. Pulled to the side of the road, turned off engine. Looked in Owners Manual, no mention of electric power steering, or where to put steering fluid. Restarted engine and steering worked. Went online and found possible chassis/frame ground issue. Ground cable on RH side behind front tire was corroded badly. Went to the dealer for a new ground strap, the dealer had 1 right under the counter. new strap appears to be plated, is this a known issue?

I took my truck in for an oil change on 5/25 and 12 miles after words, my truck was thrown into reduced engine power mode, which dropped my speed unexpectedly as I was driving. Luckily, I was in a residential area so that did not affect my safety, but there is potential that someone could have this code come up on the highway and have their vehicle unexpectedly throttled in regards to speed. The reduced engine power mode was the result of a code related to an electrical issue that ended up being the coolant control valve for the engine. I took it to a Chevrolet dealership that did the oil change, and they inspected it and determined that that part was faulty And would need to be repaired. The problem comes intermittently because The dealership drove my truck some and the issue would occasionally go away. As the part needed is on a seven month back order, the vehicle is available for inspection if needed.

Problem started while driving on the highway, I was speeding up from the ramp to merge into the highway. As I got to 62 mph the dashboard started blinking that i could only go up to 62 mph max. Cruise control was not on. I drove to my destination at that speed with the message on the dashboard. I arrived at my destination, parked, turned it off, a couple of hours later turned it on to drive again. At this point, the dashboard message was that I could only drive it max speed 42 mph and "service tire monitor system" I towed to my mechanic given i could not drive at that speed on the highway back home. The mechanic said it was time for a brake change and that might be the issue. He changed all the brake pads and rotors and the truck drove fine again for less than a week. As i was getting on the highway, the truck started to jerk like it wanted to stop as i was speeding up, i was going 45 mph. There was a clanking sound coming from the engine. Then multiple things started flashing on the dashboard; check engine, traction control, messages reading "service parking brake" and "service ESC" I turned the truck off for a couple of minutes on the highway shoulder. Turned it back on, the same messages were still on the dash. I again could only drive it max in the 40's mph. The faster I tried to go, the more heavy and forced the truck felt. I had to park it over night in a parking lot. The next day i scheduled an appointment with a mechanic in town who checked it and said i would be needing a new engine, that he had seen this same problem a couple of weeks ago on a same truck. He quoted me $9K.I towed the truck back home and had another mechanic come take a look at it, he was getting the codes 0P50D and P0304.He exchanged the 4 cylinder for the good 1 cylinder to see if the codes would change from #4 to #1 and it did not. He said the issue was internal at that point and suggested I go take it to the dealership under the warranty. Its not under warranty, it ended at 60K miles and I have 80K now.

I have a 3.0 LTRe Dura Max issue is if the (Timing Belt ) or actually the oil pump drive belt breaks the engine will lose power if this happens in the middle of an intersection or major highway you will loose total power

The rear third brake light spoiler leaks causing damage to my headliner and vehicle. I have researched this and it appears to be a known issue to GM. However, GM is saying that my vehicle is not affected as of yet. I had an estimate completed on the vehicle by a local body shop. They believe the issue involves the spoiler assembly nuts not being properly tightened and sealed by the manufacturer. A repair will cost approximately $593.63.

While driving on the interstate, my entire display panel/information queue lit up and my information display issued crazy and bizarre warnings. When this happened (I was traveling around 60 mph) immediately pulled off on an exit only to find that my brakes were out/nonexistent and my emergency break button not responding. Luckily and by the grace of God, there were no other vehicles or pedestrians in my line of travel on this exit, the exit fortunately happened to be on an uphill incline/climb which aided in slowing my truck to slow down to a complete stop, and neither I or any other person or vehicles were harmed during this incident. Was told by the Jim Ellis Chevrolet of Atlanta Chevrolet Service Manager (who by the way was a great help and resource through all of this) informed that there was a software “glitch” that had caused all this to happen. I never was told of or was informed of any software “updates” nor had any Chevrolet Dealer Service Department updated this software “glitch” when my truck was given to them for all GM mileage-tiered full service recommendations.

The tailgate opens up while vehicle is in drive. No warning lights come on, the only way I knew is that people driving beside us flagged us down. The pickup bed was full of our luggage… luckily, nothing fell out. This has happened at least 3-4 times. The last time, we were towing our travel trailer, the tailgate opened up while we were driving and got caught on our tongue jack and propane tanks…damaging the tailgate and propane tanks.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 50 MPH, the vehicle started shuddering, made an abnormal clunking sound, and lost motive power. The check engine warning light was illuminated. The contact was able to pull to the side of the road. The contact was able to restart the vehicle and drove to the nearest independent mechanic, where it was diagnosed that the engine had experienced an internal failure. The mechanic determined that the crankshaft, the lifters, an unknown valve, and other unknown parts needed to be replaced. The vehicle was repaired. The dealer was not notified of the failure. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 79,000.

While driving brakes failed and codes came on saying brake system failure 43 mph, this problem apparently is a programming issue that will cost over 600 dollars because “reprogramming” isn’t covered. Brake pads were over 50% life and it is a very dangerous error.

Around 35k miles had an engine lifter fail and needed to be replaced, covered under warranty. 07/2023 - Had front pads/rotors replaced by Chevy dealer and had loud squeaking ever since. Contacted dealer and was told they are new pads so will just need time to break in. Contacted the dealer again in Sept.Oct. 2023 and brought vehicle in for service for noise concern. They informed me the noise is coming from the rear brakes that was reported as 60% life two months prior. They replaced the rear rotors/pads and noise persisted. Brought vehicle back to dealer in December, they performed a serviced but was ineffective. In March 24 started getting some vibrations when stopping. Brought vehicle for servicing, stated there are rust spots on rotors but everything is wearing fine so this will not be covered under warranty. Also that they do not warranty sounds due to pads can have more metallics then others and they cannot determine which ones do not. I looked under forums and GM Pads seem to be a common issue with noise. My truck was perfectly fine before these brake products were installed and I would like GM to be held accountable for there inferior products leading to loud break noises and violent vibrations while braking !

Check engine light came on, I plugged my code reader in and was given P0498 ERROR CODE. Upon doing research and calling around to 3 different Chevrolet service centers I was told that it is a know issue with the fuel pump control module on all gm trucks. I am part of a truck group of over 150 and 85 of us has had this issue and all are currently waiting for the part to come in which is back ordered over months. Why has there been no recall and service bulletins yet if all 3 of the service managers agreed of the known issue.

I purchased my vehicle from Southern Pines NC and at the time it had 12k miles on it. At about 40K I started having transmission problems. It would hard shift in 1st and 2nd gears. It also would not go into reverse. Hendrix Chevy had my vehicle multiple times attempting to fix things. Telling me it was not the transmission etc etc. My power train warranty expired at 60K. I have asked for my complete service records multiple times. I have paid out a lot of money due to it "not being the transmission". The last time it was there the manager Matt took it home and said the changed the transmission fluid which was very dirty. Almost trying to say I had done something to make it that way however in the service history they had it almost the entire month due to issues. I got it back and my brakes went out while driving. I was able to cost to a stop. I was at my limit. I called Matt and said come and get this vehicle. I want Chevy to take it back. They kept the vehicle for almost 2 weeks. Matt said he personally drove it home and it was fixed. I picked it up and I have not had any issues for about 8 months or. Now my power train warranty is expired and my vehicle is again doing the same things it was when I took it in at 40k. It now has 85k. It is hard shifting in 1st and 2nd. It is rolling when in drive. I also have had many body parts that have come off etc. I called Chevy today to again get my service records. I stil have not gotten them. I just want a reliable vehicle. I feel like I have not had a reliable vehicle from day one. I want them to take this vehicle back and I want a Toyota hat is comparable in cost of my truck in its new form. Can you help me?

Water leak above the rear sliding window has soaked into carpet & upper roof inner lining panel.

A/C blower motor over heated and caught the electrical wires on fire under the dash. I had just left my house for work about 1 mile from home and the dash started smoking then a fire started under the passenger side glovebox parked the car in the middle of the street and I was able to exit the vehicle and put the fire out with a half bottle of water I had in the car. I then called 911 and I believe it was EAST Pierce fire department. They shortly arrived and confirmed it was an electrical fire and that there was no more heat coming from it. The fire department then gave me A ride home. The vehicle has been towed to Sunset Chevrolet in Sumner Washington where the Vehicle was purchased New in 2020.

The trucks installed trailer wiring can cause a traffic accident. The wiring harness is known to have electrical issues but is not being corrected under warranty. It is difficult to know of these issues until you hook up a trailer or camper. The trailer's brake light and turn signal are affected by the faulty wiring. The dealer narrowed the problem to being between the plug and fuse. Other people have voiced their concerns with the trailer wiring.

The DEF system tank and heater tube/wiring assembly need to be replaced due to the wiring melting. There should be larger wires or a fuse to prevent this. The system is tied to the Emission Controls system in the vehicle. When this happened I was warned on my dash display I had only 165 miles remaining at 65mph, and presumably slower thereafter. I live in Alaska, we travel long distances, sometimes in extreme cold temperatures and always far from help; even cell service if away from urban centers. I find it unacceptable my truck can decide to strand myself and/or family (3 children under 5) based on emissions, not run-ability. The temperatures in Alaska have been severely cold a couple weeks ago when this issue came up. The issue is confirmed by the dealership and is a known issue in the diesel community. Apparently it is a known issue for diesels in cold weather. Diesel is common in cold weather so the issue is perplexing at best. The vehicle has never been inspected by any one other than myself, a mechanic and the dealer. There were no warning lamps, only the dash warning the emission system needed service.

When you try and start the truck, the instrument panel lights up fully but when you push to start the instrument panel dims and acts like the battery is dead and won’t crank. The engine light is on. After a few presses, it finally cranks and starts fully. Has happened repeatedly and randomly.

Notice the engine temp was rising, had notice I was slowly losing coolant in my overflow tank. Then while driving it started making noise that the engine overheated need to idle vehicle then as I pulled to a stop light the rims bogged down the whole vehicle shut down The radiator has a small leak in the plastic reservoir on the driver's side of radiator. Could have cause a big problem if I was in traffic when it shut down cause I had no control to turn the wheel or anything else once that happened.The vehicle got extremely hot very fast.

Brake system failure reported on screen. Extremely hard to stop vehicle.

Rear window leaking like a small stream in regular rain. It’s going down behind seats and carpeting and headliner staining worse and worse and I am worried about black mold being created. Husband has lung issues and that can be verified by our physician. We have told Jenkins chevy in Venice florida 5/4/22, 3/20/23 and now living in TN spoke to Champion Chevy in Johnson City on 9/29/23 and 1/5/24..it’s getting worse and as we are out of warranty no one wants to help. We never received any bulletins on my chevy site and it’s not anything you would normally notice but now we smell the mildew smell back there because it is getting worse. Please help us before we get ill from this awful leak. This is my first Chevy pick up I have purchased in my lifetime. Possibly the last..

torque converter and transmission. For more than a year truck would lunge or jump forward when stopped at light or sitting in traffic, brought truck back to dealer several times for this problem each time they would tell me nothing wrong with truck. problems continued to happen and Truck started hesitating when accelerating then jumping into gear also while driving on highway truck felt like it was slipping out of gear and RPMs would jump up. Brought truck back to dealer again 3 months ago and they said torque converter was going bad and they would call me when part was in. two months later and they kept saying it was back ordered, now while driving going down steep incline into busy intersection felt like i got rear ended by another car, when looking back no car was close me truck stalled and started rolling into intersection I slammed on brake and got truck started again only to find transmission had failed and it slammed into gear when accelerating put my flashers on and got off road . Brought truck back to dealer to have them tell me transmission was now gone. truck has now been sitting on dealer lot for a month now with them telling me they can't get parts or transmission to fix. Very dangerous situation with this transmission and them knowingly kept sending me away in this truck. I feel that they knew about transmission problem over a year ago when I was bringing it in for the lunging forward after coming to complete stop at traffic light and kept saying nothing wrong. Truck was still under original warranty and only has 62k miles on truck.

While driving the engine jumps/jerks then goes back to normal, it continuously happens every 3-5 minutes while driving. A friend had his exact issue with exact make model year vehicle and it ended up being the gas sensor. Please look into this issue for this vehicle. Our local dealer will not fix it because the sensor doesn’t show the issue but that is the issue. The dealer knows it does it but won’t fix it.

Driving 20 mph on paved downtown street when cross arm failed causing wheel to twist 90 degrees causing damage to brakes, drivetrain, abs, and steering. No warning just pop and trying to maintain my lane before able to turn into parking lot. Towed to dealer and diagnosed with control arm failure. They are aware of this issue and now replace control arms stronger rough country control arms and level the truck differently. DeAler is claiming GMC will not cover and they are calling it a suspension issue and out of warranty two months. Truck has 26000 miles on it. Lucky event happened at 20 mph and I was able to maintain control of vehicle

The rear power sliding window in my 2020 Chevrolet Silverado 1500 LT leaks whenever it rains. The leaking water enters the cab and runs down the back interior wall of the crew cab and saturates the insulation material and the carpeting on the floor. The moisture has caused the seat brackets that attach the seat to the truck to rust and it has also caused mold inside the cab. I purchased a DIY mold test kit and it was positive for mold. My kids and I have allergies and this is causing issues with our health and if it continues it could cause serious health problems. This known issue of the leaking rear window is very widely discussed on many different gm truck forums and internet sites yet gm will not take ownership of this obvious problem.

Today while driving , the upper ball joint separated from the control arm, causing the truck to pull hard to the right. I was able to keep from wrecking the truck. While doing research it seems that this is a common occurrence with the Silverado Trail Boss and the Sierra AT4. I read a safety recall report on these vehicles, 21V-718, after reading this, it's exactly what happened with my truck. Ball joints is rusting and corroded. Vehicle is able to be inspected upon request. If I had been on the freeway traveling, it would have caused a severe single or multiple car accident as I lost control to steer. No symptoms leading up to the situation.

My backup camera is not functional and it stopped working in April a month after I purchased the vehicle before my lease expired in May. I took it into the dealership for a software update and they refused to do anything without charging me a $160 fee.

Truck shudders, with varying degrees of vibration, emtek applying brakes. It is especially rough when applying brakes on the highway as it feels like it could lose steering control. Shaking is also very noticeable at slow speeds. Have had rear brakes serviced and problem persists. As of this month, the "service ESC (electronic stability control)" light has come on, along with other faults on the dash. VIN does not indicate unrepaired recalls, but this issue makes the drive feel dangerous

water leaking across head liner/ rear sliding window junction. leaking on to granddaughter in child seat. bought truck new, may of 2020. garage kept, day and night. less than 22,000 miles.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at 30 MPH, the vehicle briefly vibrated and shuddered before losing motive power. After tapping the brake pedal and rapidly accelerating, the vehicle continued to vibrate and shudder but eventually returned to normal functionality. No warning lights were illuminated.

The failure mileage was 78,000.

Brake calipers on 3 of 4 wheels are trying to lock up. Only 54000 miles on the truck this should not be an issue. Could KILL someone

the transmission on my truck shudders and shakes very badly, contacted GM ,also the dealer told it would take 3-4 weeks to repair , i am left without away to work.

Started to notice water marks on the driver and passenger side rear window. According to online forms it is a common problem with 2019 and 2020 silverados with a sliding rear window. The dealer claimed it wasn't a safety issue, which I argued it was due to the mold. Chevy knew about the manufacturing problem before they even sold me the vehicle and did nothing to fix it

I am writing this complaint to bring up the melting dashboard on my 2020 Silverado. I took my vehicle to Beaver Chevrolet in Jacksonville ,FL and they identified that there is an issue with my dashboard. However, they refused to fix or replace it. The service manager check his personnel vehicle and confirmed that his is sticky as well. My co-worker who owns a 2020 GMC Sierra also has a sticky dash. This issue is dangerous as my dash is very shiny and reflects everything onto the glass making it very difficult to see.

Loss of power steering, on 2 occasions. Started the vehicle and got a caution notice saying drive with care power steering disabled. Sure enough no power steering. Stopped vehicle waited, re-started vehicle, problem persisted. Made other transportation arrangement plans, restarted vehicle after a bit a problem seem to be gone. Stored codes we're 121, 131, and 140. BCM Communication loss, Power brake communication Loss and Steering Control communication failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving approximately 60 MPH, the steering wheel seized. The "Loss of Power Steering - Drive with Care” message was displayed. The driver pulled over, but the failure persisted. The vehicle was taken to the local dealer, where it was diagnosed that the steering module and steering column needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 74,000.

My car turned left with the risk of jumping to the opposite lane. It happened twice. First at 40 mph and the second time at 70 mph. I didn’t feel any issue with the steering drive but more with the traction. I’m not sure.

About a month ago I noticed some intense shaking in my 2020 Silverado 1500 RST when braking. The shaking is not only felt in the seat and steering wheel, but is also observable in the dash and in the gear shifter. Due to the obvious concern, I made an appointment with the dealer who, after inspection, stated that all 4 rotors were warped due to overheating. I mostly use the truck on the highway, tow a river raft (easily carried by 2 people) on a small trailer 2 times a year (about 70 miles roundtrip), have never used the bed with excess weight, do not ride my brakes when driving, and I live in Alaska where the temperature is cool (high temps rarely exceeding mid 60's). The brake status report on my dash presently shows my original brake pad life to be 83% on the front and 89% on the rear which was inline with the dealer report that the brake pads were still quite thick. These prove that the brakes have not been overused or abused. According to Kaufman and Associates website, "General Motors is recalling over 350,000 2020 Chevrolet Silverado and GM Sierra pick-up trucks due to a fault in the brake system....The issue involved a lack of heat-treatment for the bolts used to attach both the front and rear calipers.....The issue comes down to long-term performance and safety....Untreated bolts run the risk of breaking under loads, and this can result in braking issues, wheel rotation problems, and internal damage to other parts of the truck. These trucks also suffered from brake system control module and premature brake wear issues, and countless owners have reported brake system issues as varied as check engine lights to outright brake failure." According to the local dealer, my VIN isn't included in the recall and they cannot fix it until it is included (or I dish out $2k). It seems obvious that the issue in my truck is the same that led to the recall of the other 350,000 trucks and I simply need my VIN added so that it can be fixed before catastrophic brake failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle was shuddering while depressing the accelerator pedal. The contact also stated that after cold starting the vehicle, the vehicle shifted hard from first to second gear. There was no warning light illuminated. The vehicle was taken to a dealer where the transmission fluid was flushed; however, the failure persisted and became more frequent. The manufacturer was notified of the failure and agreed to cover half the cost of a new transmission. The vehicle was not repaired. The failure mileage was approximately 59,000. The VIN was not available.

The key will get stuck in the ignition cilinder when I try to turn off the truck. This happens several times, I got to turn it on and off several times to get the key out of the ignition barrel. The truck was taken to the dealer to be repaired, they replaced the cylinder (part #13528553) and the housing (part# 84990323) AMD it didn't fix the problem

while driving i smelled what i thought was strong exhaust from a vehicle in front of us. It was actually gasoline fumes entering the cab from my truck's engine compartment. I pulled over and investigated the smell, we had to let down ALL the windows and turn off the AC. There were no warning lamps. There was, however, gasoline dripping from around the transmission area of the underside. It was dripping on the exhaust which was causing most of the stench. It wasn't a heavy drip but enough for me to skip any other planned errands. When we got to the house gasoline was dropping from six or seven places under the car. The next day we set an appointment for the dealership to look at it. When I drove into the dealer the car was still gushing gasoline and I told them about the recall for the High Pressure Fuel Pump. It turns out that's exactly what it was. However, although my RPO (L82) matched the designated recall, I was told my VIN was not included and I would have to pay...bummer. I don't think the recall cast a big enough web to catch all affected vehicles. I have a video but no photos.

Bought this vehicle 4 months ago first month the tire loosing air went on a trip park in a garage left it there for the week end came out passenger front tire was flat put spare on notice crack on inside of the rim...2 month later took another trio on the way home tire was loosing air change out again Crack on inside of rim driver rear different one then first time

Already paid for transmission repair and now paying for engine wiring harness. Service update was sent out to dealer in May of 2020 to fix issues before selling vehicle. That was not done.

Lifters are failing. This is an ongoing problem with GM engines. They used faulty parts and engines are failing and nothing is being done about it.

I am concerned of the blind spot created by the size of the right and left support structures on either end of windshield. They also have a grab handle attached to them increasing the size. When at a stop and looking for cross traffic they create a blind spot of approaching vehicles. I believe this was why I thought no traffic was approaching when i entered roadway and then saw a vehicle approaching from the left. I immediately came to a stop and avoided an accident luckily.

at around 30mph the transmission struggles and jerks.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 65-70 MPH, the engine started shuddering.

Rear window seal is leaking causing mold in vehicle.

Everytime I trun the car off, all the lights, Nav, radio stays on as the car display a message "Shift to Park". This message stays on for sometimes 2 minutes, sometimes 10 minutes. Untill the message gone the car still thinks is on. In 2 occasions I had to jump the car as the battery depelted. This is a major safety issue if my son who drive the car to Detroit and had to stay wait for the car to turn off. GM need to fix this issue ASAP. I called the dealership & they said there is no recall or any fix. I see many many ppl complaining about the same thing with different Chevy models.

I had just left RV Park in Kingman, AZ. I had cruise control set at 59MPH when My truck began a violent shacking and a lot of banging. I pulled over on the shoulder of I-40, Got out to find tread had come off of the tire and was now wedge between brake backing plate and leaf spring. It had not lost air. Just tread came off. When tow truck driver showed up several hours later, tire was still holding air. He jacked up the axle, but deflated tire before he would remove it from truck and put on my spare. I always check my tires when I leave rv parks or after stopping at rest stops. Saw nothing wrong with tire or air pressure that morning. I had only been driving 45 Minutes, outside temp was low 80's.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that there was condensation leaking from the rear window third pane. The contact observed discoloration near the condensation.

The failure mileage was 50,000.

While driving down the interstate hi-way, I heard a pop and my truck started to swerve into the adjoining lane. I turned the steering wheel in the opposite direction and the truck started making a rubbing sound and very hard to steer. I finally got it to the side of the hi-way and seen my passenger side front wheel leaning in. The upper balljoint/control arm broke. Luckily no-one was in the lane next to me or it would have caused a serious crash.

dash gauge cluster - ALL gauges drop to "zero" while driving speed, oil pressure, engine temp, fuel, etc., a/c compressor stops working but blower still works

2020 Silverado 1500 LTZ, Turn signals on mirror do not work

Electrical acutated tailgate will not come down. The truck came with a soft bed cover that locks. If my child was to hide in the bed somehow it would pose an immediate risk to life and health as the tailgate will not come down and does not have any type of manual override. The interior controls do not work to lower the tailgate, the key fob controls do not work to lower the tailgate.

Brake system light failure. Some system lights came on. I had no breaks car didn’t stop fast enough before hitting a pole

I purchased this truck new and it's now been back 8 times for a engine hesitation, misfire, and check-engine light. On this 8th visit, they replaced the "right bank" of lifters on this 5.3L V8. Previous visits have replaced fuel injectors, spark plugs, spark plug wires, and flashed the ECM. I'm not sure why GM didn't replace the left bank of lifters if it's a known bad part (or replaced the engine entirely). Now I'm just waiting for the problem to come back for a 9th time for yet another part to replaced on an obviously poor engine design.

Was riding down the road and my front left caliber locked up had break fluid running down from the upper reservoir the truck only has 46,000 miles. the truck was immobile had to have it towed and had to get a new caliber and took the shop almost a week to get air out the system breaks are still not 100 percent also rear breaks are having a problem fully releasing as well. Leaves me worried the rear breaks will seize up as well cost me 1000 dollars for the repairs

On a 3 year old vehicle, I had a dash full of warning lights come on along with the engine light. Upon checking the code for the engine, it shows a misfire on cylinder 5. Looking online, chevy has a tsb # pip5776c regarding lifter failure. It appears this is an ongoing issue with many of the vehicles as verified by an engine repair shop. They stated then engine may need replacement as they have found in the past. For a 3 year old vehicle with more year of payments this is not right. They know of an issue and after speaking with a dealer, they said its on me because I am over the mileage warranty. I do not have the repair done yet--it is not cheap

Component? Multiple: lifters from bank 2 which caused multiple other components to be replaced consistent with GM protocols such as bent rods. Safety: The vehicle jerked causing it difficulty to safely operate the vehicle which ultimately left stranded. This was also unsafe for other motorist as it was difficult to operate while trying to safely get to the side of the road. The dealer repaired the vehicle after confirming failures. No one other than the dealer inspected the vehicle to date. Warning lamps only appeared after vehicle violently shook.

VEHICLE WILL SEND MESSAGE TO MESSAGE CENTER TO SHIFT VEHICLE IN TO PARK WHEN IT IS ALREADY IN PARK. HAVE TO TRICK VEHICLE SYSTEM TO MAKE IT BELEIVE IT IS IN PARK TO TOTALLY SHUT DOWN VEHICLE

Rear window seal leaking.

My transmission went out

Vehicle is at 67,xxx miles. Vehicle is losing power, check engine light, service 4wd, service esc, service power steering, service parking brake..... the gas pedal has locked on me already with my 3 small children in the truck at highway speeds. GM says it's fine. I have all the work orders where 2 different dealerships have "corrected" these issues under warranty. Go retrieve the vehicle and within a week Vehicle is back acting up. This truck is unsafe to drive on the roadway. I have not been offered a courtesy vehicle to drive while "warranty" work is being done. I am appalled and in fear for my children and my own life with this truck.

Power Train Transmission Torque Converter “Chevy Shake” Multiple symptoms. - Shuttering , “ buffeting” , slipping sensation. Continuous almost like “strong wind gust” or “head wind” - Humming, if you have ever heard a “high pressure” hydraulic equipment. - RPM bounces 300 to 500, but transmission does not “down shift” (while driving) - Vibration, of the truck can be noticed, felt at various speeds, 40mph to 60mph(shutter) almost like it struggling to get up to speed (unless heavy on the gas pedal) 70mph and above to say 80mph, then shaking, vibrations worse when coasting back to 70 mph Vibration will “not stop” until truck speed is drastically slowed or come to a stop. - Steering wheel “shakes” , “vibrates” also can happen at 60mph to 70mph and above to say 80mph, then worse when coasting back to 70 mph - “Clunk” when stopped and shifting into “reverse” (new development symptom) Vehicle is in for inspection. It keeps reading service break system. Service ESC

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at various speeds there was a loud noise present coming from the front end of the vehicle. The vehicle was taken to the local dealer who discovered that the front driver’s side axle was fractured.

The contact also indicated that while his wife was driving, the odor of fuel was present inside the vehicle. Upon inspection, his wife discovered fuel leaking from the vehicle. The vehicle was taken to the local dealer who diagnosed that the plastic fuel line had cracked causing fuel to leak from the vehicle. The plastic fuel line was replaced, and the failure was fixed. The manufacturer was notified of the failure. The failure mileage was 25,000.

Power steering failure upon starting truck. Wheel did not turn. Dash message said Esc and power steering malfunction . Restart car multiple times with same issue. Wait a few hours and start car - no warnings or power steering issues. Went to Chevrolet dealership and was told no codes had been triggered and to bring back when issue arises again.

The frame of the truck is excessively rusty and the manufacture undercoating has flaked off. All components of the frame and underbody have significant rust for the age of the vehicle. This was just addressed with the dealership who stated there was no warranty to cover it. There has been no service done to the frame and all preventative maintenance and service checks have been done at the dealership on time. It was just recently noticed to be so rusty. This poses a problem with the safety of the frame of the vehicle which can lead to cracks, broken welds, holes, etc.

The contact's husband owns a 2020 Chevrolet Silverado 1500. The contact stated that while her husband was driving at approximately 65 MPH, the vehicle suddenly decelerated to 40 MPH. The contact stated that the failure recurred on various occasions and that an unknown warning light was illuminated.

Transmission will hard shift from 2-3. It jerks the truck and causes power loss when in traffic. The RPM's will go up to 3500-4000 and then the truck barley keeps a speed of 45 mph. The engines sounds like it is going to explode! This has happen several times with 32000 miles on the truck.

The tucks are high so a backup camera is now more important than ever. During the day the image very grainy but useful. At night or in a dark garage it completely useless. I took my truck in to be checked and they agreed it was terrible but nothing could be dome until a recall was issued. I've done research and this seems to be a huge problem with the 2020 Silverado. I reached out to Chevy and the lady I chatted with said I should file this here with you. There are multiple chats and message boards about this issue and Chevy lack of being willing to fix it.

Trailer brake controls not working. Safety at risk due to electric trailer brakes not working. Other lights and functions work when trailer plugged in.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the trailer disconnected from the tow hitch. Additionally, the trailer brake warning light was illuminated. The vehicle was taken to the dealer and brake switch was replaced; however, the failure recurred. The vehicle was not repaired. The contact related the failure to GM PIT: 5948A. The manufacturer was made aware of the failure. The failure mileage was approximately 2,000.

The contact's son owns a 2020 Chevrolet Silverado 1500. The contact stated that while her son was driving approximately 60 MPH, the vehicle stalled with the "Service Brakes System" message displayed. The contact stated that the failure recurred and that the vehicle was unable to accelerate over 40 MPH. The vehicle was taken to a local dealer, where it was diagnosed that the brake master cylinder needed to be replaced. The vehicle remained at the dealer awaiting the repair. The manufacturer was made aware of the failure. The approximate failure mileage was 45,500.

I have 75,000 miles on my vehicle and in the last 15,000 miles my check engine oil keeps going off. I change my oil every 5000 miles, I am having to add 1 quart of oil about every 1000 miles. I do not see any leaks or old oil on or around engine.

Truck was purchased new in 2020. The transmission has worked fine until recently. Since this summer there is a distinctive whine coming from the engine department. Very hard to isolate. The transmission this winter has been terrible. The cold functionality of the transmission now is even worse than when new. It hesitates to shift to second and to third gear when cold. The transmission now also exhibits a failure to up shift when the vehicle is moving. It will hang with elevated rpms 2300 to 3000 for a second or two before upshifting and lowering the rpms. The truck now also has random clunking when shifting into reverse from dead stop. The transmission does not shutter but there is definite loss of power and that can be contributed to a bad torque convertor. If it is not locking up correctly when in gear power will suffer to the convertor failing to engage the transmission correctly. The shifting issue have persisted and gotten worse. Dealer said he put a computer on it and said there were no codes. The dealer mechanic did not even try to road test the truck That is just ridiculous. I will be taking the truck in again

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 55 MPH and coming to a stop, the check engine warning light and traction control warning light illuminated. Additionally, a message indicating that the brakes had failed, and the vehicle could only drive at 40 MPH was displayed. The vehicle was taken to the dealer and the brake master cylinder was replaced; however, the failure reoccurred while driving and coming to a complete stop. The vehicle was taken back to the dealer where the same repair was completed; however, the failure persisted. The manufacturer was notified of the failure and sent the parts to the dealer for repair. The vehicle was not yet repaired. The failure mileage was approximately 64,000.

I drove approximately 8 miles to lunch and parked the truck. It sat about an hour and when I started the truck to leave I had a message to service esc and power steering reduced. The tuck had no power steering. Returns to work and the truck sat about ten minutes. Then everything started normal and is fine.

At approximately 42k miles my 2020 Silverado started flashing a very frequent “service safety restraint system” warning light and beeping (either constant or every 10-15 minutes). Immediately contacted a Chevrolet dealer to have it corrected. They have assured me that the repair is simple, will cost me $602 to replace a few steering wheel component parts to get the clock spring working correctly. They assured me they knew the issue would be resolved since their tech has “seen this a lot” but it took them all day to diagnose, and said since I was just past my bumper to bumper warranty it was not covered. That I could pay the diagnosis fee and take it home if I wanted. Since when is a faulty safety restraint system “fine” to drive? Of course I immediately authorized the out of pocket repair to be safe, but I am surprised and alarmed that Chevy would allow them to return an unsafe vehicle to a customer and tell them it’s “fine” rather than put them in a loaner vehicle or report the issue, since there are thousands of similar complaints for these Silverado’s. Truck is currently in the shop, on my dime and I am terrified that this will end up costing me more than $602.

Shaking an jerking in transmission in all gears.could be a serious issue if it locks up or stops pulling at speed or in heavy traffic

The 2020 Chevrolet Silverado has a known issue with the torque converters and they are currently on back order and our service manager told us we are able to drive with it messed up and that it would not cause anymore damage but it causes transmission lockup and engine lockup which results in loss of control.

Lifter failure caused several different warning lights and misfiring and chugging. Vehicle never died, but might have if it had continued to be driven.

Brake system failure. While driving vehicle, brake system and traction control stopped working. Vehicle was then limited to 62 MPH. Almost no braking available and pedal needed to be pushed very hardly to the floor.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that after starting the vehicle and attempting to drive out of a parking spot, the power steering failed to function as needed. The contact stated no warning light was illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the wiring harness for the power steering needed to be replaced. The vehicle had been repaired. The manufacturer had been informed of the failure. The failure mileage was 44,624.

I hit a concrete light pole at 10-15mph on the right side and zero air bags went off, I hit my face and arm and chest on steering wheel, broken my nose, messed left arm up and brushed left lung it’s got fluid on it and ribs are bruised it’s hard to breathe and move after a week happened on 2022 thanksgiving around 1030 pm cops showed up truck was undrivable, had X-rays and Ct scans and have a heart scan this week,

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the steering wheel became difficult to maneuver. The ESC warning light was illuminated. The contact then stated that he turned off and restarted the vehicle and the steering wheel returned to normal operation. There was no warning light illuminated; however, the vehicle was taken to the dealer where the failure could not be determined. The manufacturer was not notified of the failure. The failure mileage was approximately 63,000.

I keep getting battery saver activated. I go to start my truck and it will not start. On dash says battery saver activated. I have had in the dealer 4 times and it keep happening. I also have had the power steering go out while driving. This has only happened once and after a couple hours it started working again but seems very dangerous.

This is a huge vehicle. Side indicators were required back in 1968, and yet this monster truck doesn’t have any definitive side markers. Also, the standard package does not have any turn indicators on its side mirrors. Even compact cars have this safety item.

I was involved in a 3 car accident where I was stopped and rear ended into another vehicle in front of me. My car experienced severe damage which led to multiple minor injuries and a concussion because the airbags were not deployed. Because they were not deployed, I aggressively hit my head on the steering wheel and dash area of my vehicle. I had my seatbelt own but because of the airbag not deploying, I experienced multiple injuries. The vehicle that rear ended me was going 40-50 mph when they collided and pushed me into the truck stopped in front of me. I did receive an alert right when this happened from my application on my phone stating “Issue with Airbag system. Schedule Service Now” meaning that the airbag was not able to deploy when it was supposed to do so. The police, ambulance staff and witnesses all did not understand why the airbags did not deploy considering how hard the collision was. As a result of the airbag not deploying both my wife and I have injuries to our head and neck and and multiple areas of our body.

Vehicle exhibited sudden loss of power at highway speed while in West Texas. Without warning, the vehicle displayed an "engine power reduced" message and the vehicle immediately slowed from highway speed to a maximum speed of 25mph. This sudden reduction in power required the drive to take emergency action to leave lanes of travel for the shoulder. On a road with insufficient shoulder-area, this could have resulted in a collision. Prior to the loss of power, a check engine light illuminated followed by a "Service Emissions System Soon" warning on the driver information display. The elapsed time between the messages and the loss of power was less than 5 minutes. The vehicle did not exhibit any erratic behavior at the time of the warning lights or prior to the loss of power. The vehicle is currently at Bill Estes Ford in Indianapolis, IN. Diagnosis is underway. Indications are that this is related to issues with the emissions control system. The vehicle was up to date on all service at the time of the incident.

Sunset jerking of vehicle, hesitation of vehicle when accelerator is hit at random times, when taking off from a traffic light or while cruising. If simmering need to get out of the way this could lead to vehicle hesitation and safety issues that could cause a crash. No errors were given in computer when dealership looked at it.

Torque converter faulty and told vehicle unsafe to drive. Only about 12,000 miles on vehicle. It was skipping gears while driving. It appeared initially very small and almost unnoticeable, but got worse over time going back a few weeks at least. The dealer has had the vehicle for over 30 days and cannot get the part shipped to them. They told me it MAY be shipped on October 22, while I dropped the car the first week of September.. Being told it is unsafe to drive, it definitely put us in danger driving it. Service Bulletin so they know about the problem: https://static.nhtsa.gov/odi/tsbs/2020/MC-10184489-9999.pdf

Truck mileage approx 26000 miles. 2 wiring harness locations rubbed wires enough to cause wire to wire contact resulting in 1 location, burnt wires, according to service tech and the other resulted in truck malfunction. Threw numerous codes, transmission repeatedly went P, D, P, D....unable to put in park for sometime and then finally was able to. Additionally, when serviced out of state, was recommended to have service done for leaky oil pan. Upon returning to home state, truck went in for oil leak, was returned due to parts ordered because it's leaking at the rear main seal and not the oil pan. Waiting on this service to occur.

First I I’d notice my pedal kick every once in a while then pulling into driveway all warnings kicked on and truck was hard to stop almost hitting garage. I got engine light, traction control light, and brake light ,service ecs,brake system failure 43mph max speed , service brake assist

Purchased the truck through CARMAX and two weeks later received the “Service Brake Assist” and “Brake System Failure” message on the Console. This has happened twice in in one month.

Vehicle didn't start; got stranded. Tried to jump start with another vehicle. It turned, but didn't turn on. Had it towed to mechanic (closed on Sunday). Was lucky to be in an area I was familiar with during the day and not traveling over 250 miles the following day with family at night. Mechanic called Monday and stated fuel pump has to be replaced after a diagnostic test. 2020 Chevrolet Silverado @ 50,000 miles

Vehicle was parked. Rear window shattered.

Locks will go up and down by themselves tranmission will downshift randomly broke down on highway service light service esc service parking brake and traction control vehicle only has 32,500 miles been complaining nothing getting done just want something else.

Transmission keeps over heating to the point that a message comes on display “Transmission hot idle engine” have had this same problem before to it to the dealership they installed a temperature bypass on and this problem continues

While using backup camera, display is intensely bright and blinding. There is no dimming function. Display reflects off side windows making visibility to side mirrors impossible.Very dangerous to backup in the darkness.

My truck felt like running over rumble strips. At 17500 miles they replaced my torque converter under warranty. Now at 24690 miles they had to replace again, under warranty. With less than 25000 miles it is on it's 3rd torque converter. I fear that transmission is being damaged and feel Chevrolet needs to admit there is a problem. My current dealer calls it a lifetime warranty, with lots of strings, but Chevrolet should protect me.

Passenger door lock failed. Door will not lock with any door button, key fob, automatic lock function, or when vehicle shifts to drive. Door must be manually locked by pressing lock down and unlocked by pulling door handle risking safety of passenger. Issue has been reproduced, inspected, and confirmed by independent mechanic but no diagnostic has been ran yet. There were no warning lamps, messages, or symptoms present prior to failure.

My Silverado 1500 has developed torque converter shudder again over the course of the past few days. My current mileage is around 42,000. This is actually the second time this has happened on my specific vehicle and the current torque converter is actually the second, as I had my other one replaced after being confirmed by a dealer several months ago. I have only managed to drive around 10,000 miles between the replacement of the first part and the start of the second one failing. For information regarding the first failure please use reference ID 11458308. This has not yet been confirmed by a dealer, but I'm scheduled to get this serviced on Tuesday. I am certain that is what this is as this happened so recently. Primarily while driving at highways speeds between 1500 - 2000 RPM my Silverado will continuously surge forward every few seconds with a notable clunking in the rear. While this is happening I will watch my tachometer bounce up and down approximately 300 RPMs constantly, despite the fact cruise is set and this is on flat ground. The problem gets worse while driving uphill and increases the magnitude of the clunking/shaking. Under light throttle acceleration my truck will have a vibration coming from under the vehicle that feels exactly like driving over a rumble strip. This was the sensation that helped the dealer identify this as torque converter shudder the first time. No warning lights were present at time of incident.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that upon purchase of the vehicle, he noticed an orange-colored rust underneath the chassis of the vehicle. The salesman assured him that the rust would be cleaned off once the sale was finalized. Months later, the contact noticed the same orange colored rust had returned. Upon inspection of the vehicle, he discovered severe corrosion located in several spots on the subframe. The contact took the vehicle back to the dealer for the repair. The contact then received a call back from the dealer and was informed that no corrosion was found, the dealer linked the failure to structural rust. The contact disputed the diagnoses and the dealer agreed to have a further inspection performed on the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 65,000.

Popping and/or Clunking Type Noise Heard During Hard Turns at slow speeds and backing up. Seems to be a problem with the control arm

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that after being parked for several hours, the vehicle was started and operated in drive(D) and reverse(R) however, the vehicle failed to turn to the right or left. The contact stated that the steering wheel had seized. The contact was able to disconnect the battery then reconnect the battery once the torque rebooted. The failure occurred twice. The warning light displaying an open wrench stating ESC needed resetting was illuminated. The vehicle was taken to the dealer who was unable to duplicate the failure. The dealer stated that the failure might be caused by the sensor in the steering column, or the module. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 13,500.

While driving, the service emission system light activated indicating the truck would be reduced to 65mph. This was due to a faulty EGR wiring harness that controlled the EGR sensor.

The Advanced Trailering system will fail to load, preventing the user from entering the correct vehicle being towed and the entire system screen is blank and won't load. This could be a huge safety concern if the driver cannot select the correct vehicle being towed since the Brake Gain is stored in the Advanced Trailering system and then the incorrect amount of braking force will be applied to the vehicle while it is being driven, which could cause insufficient or excessive braking forces applied to the towed vehicle. This could lead to rear end crashes or Jack-Knifed crashes. The problem is random but repeatable quite frequently and has been confirmed by the Dealer (refer to included GM Bulletin PIT5792 Published on 11/5/2020) GM has been aware of this problem for almost 2 years and has not provided a fix for it. I have had this vehicle in the dealer on at least 3 occasions to fix the problem There is no advanced warning, message or other symptom prior to this problem. The problem started within a month of purchasing the vehicle

My truck had been randomly misfiring but the dealership couldn’t resolve the issue because the check engine light would go away on the way there. They were able to pull codes showing a misfire taking place and told me to return if it continued. The truck started having misfire issues again periodically fir the next 2 weeks but once the check engine light stayed on I scheduled an appointment. On the way to the appointment to Hidiburg Chevrolet we were on the interstate the cruise control kicked off, the service parking brake indicator, misfire flashing of check engine light, an ESC warning, and the traction control light came on as the truck randomly pulled to the right real quick then it stopped. Once the indicators went off all warning indicators were off and cruise control would not work. The dealership pulled codes and saw every cylinder misfired and that the other issues that took place. They tested everything and could not find the source and said that they had to wait until the indicator stayed on so they could see the issue. I left with no resolution and concern that when the misfiring could damage parts and the computer. I also fear that the issue if someone isn’t aware of vehicles not fixed could lead to severe accidents and potential for death if not fixed.

Both front upper control arms are corroded.Vehicle is 2 years old and has 10375 miles.Dealer stated there is no outstanding recall or a TSB associated with this issue.This is a Trail Boss model with a lift kit from the GM.There is another recall that was issued for 19-21 models with lift kits with the same issue but apparently this model is not matching that yet the problem is very obvious.Please also note that the vehicle was also rustproofed immediately following the purchase.

As I was backing out of a parking spot in a lot my vehicle lost it's power steering. I got an Service ESC error code, a wrench indicator, and a service power steering/drive with care warning. I also got a diagnostic alert from On Star. Diagnostic Alert: Service Antilock Breaking System in your 2020 Silveragod pithing the next 7 days. I was unable to move steering wheel, and could only pull my vehicle forward. So it was stuck sideways in the parking lot for about 20 minutes. My car did restart again and the code cleared. I was able to drive it to the dealer. They ran diagnostics but were unable to duplicate the concern. They did find a history of 1 fault where several modules (ECM, EBCM, TCM, TCCM) had lost communication with the power steering control module. They also looked at Data Com schematic doc 5257308 and found modules before connector X182 had lost communication. My safety was a risk in this situation because I was stuck sideways in a parking lot with very limited ability to move my vehicle for incoming or outgoing traffic. Had this happened while I was driving the vehicle in a roadway I believe it could have caused an accident. The dealership did find that a harness was making contact with the upper control arm bolt. They re-taped the harness and secured it away from the control arm bolt and bracket. A new bracket was ordered.

I was driving and a few different warning appeared. Service Parking Brake, Service Trailer Brake System, Steering Assist is reduced Drive with care. Along with these warning my speed was limited to 62 mph, my steering was reduced and my braking was reduced, all 3 of them to dangerous levels.

I am a volunteer firefighter. On Friday, June 24th 2022, I was responding to an emergency call around 1am. There was an active rainstorm and standing water on parts of the street. While driving through roughly 5-6" of water on the way to the fire station, my truck's engine suddenly shut off and I came to a stop. While stalled, I watched multiple cars travel through the same intersection with no issues. My fellow firefighters helped me get my truck to a nearby parking lot to sit and dry out. The following day my truck still would not start so I had it towed to the dealership where I leased the truck which was still under a full bumper-to-bumper warranty. After initial diagnostics, I was told there was water in my intake and I had to get my insurance company involved for the dealership to continue with the repairs. With no other choice, I opened up a claim and was given an estimate of over $9,500 for the repairs due to the engine being "Hydro-locked". I called GM and filed a complaint. They called the dealership and called me back stating the dealership told them I drove through a flooded road and damaged my engine. I did some brief research online and found several examples from multiple sources with the exact same issue. I feel that this is a design flaw and that this needs to be investigated further as I was stranded by myself, in a heavy rainstorm, in the middle of a roadway at 1am. There is no reason that a 2020 Chevy Trail Boss should not be able to travel through the amount of water that stalled my engine. There was nothing negligent about my actions and at no point was I worried about traveling through the water that I drove through. I feel like I am being treated unfairly in this situation and I would like someone to look through the databases to see how many similar consumer reports there have been regarding this design flaw. This is a major safety issue!

The component that recently failed on my 2020 Chevy Silverado is the side detection/blind spot warning. It no longer works and upon startup of my vehicle the notification on my dash shows “side detection temporarily unavailable”. This problem started 3 weeks ago. After doing research online, it seems that there is a common issue in Chevrolet vehicles with water getting into the rear sensors in the bumper. There were also several new model Silverado’s with the same issue. As you can see, this is a safety issue as this feature all of a sudden stopped working on my truck so I no longer get warned if someone is in my blind pit while I am driving. I contacted my local Chevrolet dealership and they stated that because my vehicle is over 30,000 miles (36,000), I am no longer covered under warranty to have this issue repaired. My vehicle is scheduled to be looked at by the dealership on 6/27/22.

Transmission shuddering and shaking while driving. Once in blue moon service light flashes for less than 1 minute then goes off with no diagnostic codes to show.

ABS light came on during breaking to avoid an accident and did not break the vehicle at all. Now there is a alert on the Driver Information Center(DIC) stating a break system failure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while stopped in her driveway, the vehicle started rolling forward. The brake pedal was depressed aggressively several times however, the brakes failed to respond. After several attempts, the vehicle came to a stop. The vehicle was taken to the dealer where the mechanic stated that the failure could not be duplicated. The manufacturer was notified of the failure however, there was no response. The failure mileage was 14,562.

I have been researching rust on frame components and found there have been service bulletins issued (e.g. PI0564K) for this same issue. However, the latest service bulletin only covers up to model year 2019. Is there anything in progress to extend to model year 2020?

Electronic problem caused failure of power steering.

I bought the truck a year ago drove it home it stalled out on me for no reason thank goodness I was in a neighborhood when that happened, fast forward a year of driving it and now my gauges aren’t working it’s throwing all these warning signs and spent a lot of money on this truck and for what for all these problems that it’s having it’s my only vehicle for my kids and me and the wife and now I’m worried it’s going to cause me to get into an accident.

When I drive this car on the free way or on a very windy day, a loud air gap is caused by the front driver and passenger window. It hasn't been inspected by the dealer or anything but I believe there could be something wrong with the quality of glass or the seal that hold the glass. I've also driven with the windows lowered on a windy day and saw the edge of the glass bend. I'm worried it's gonna snap or shatter one day. It's been happening since I bought it but I didn't notice until I drove on the free way.

Vehicle had several lights on dashboard and messages, service brake system,engine power reduced, service trailer brake controller, service esc, service power steering. Vehicle lost power steering and brakes were nearly all impossible to push…luckily I was near my house and got home safe, my family or myself could’ve been seriously hurt

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving and attempting to accelerate, the vehicle shutoff without warning. The vehicle was taken to the local dealer where it was diagnosed that the computer module was faulty. The vehicle was repaired. Additionally, while driving, the brake pedal was depressed however, the vehicle failed to respond. The vehicle revved and there were several unknown warning lights illuminated. The vehicle was towed to the same local dealer however, the mechanic was unable to duplicate the failure after performing a test drive. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but no assistance was provided. The failure mileage was approximately 16,000.

Airbags failed to deploy when I hit a deer going 50-55 MPH. There was a chemical smell after the impact but no airbags deployed,

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle experienced reduced engine power. The reduced engine power warning message was displayed. The vehicle was towed to the dealer where it was diagnosed that the rear main seal needed to be replaced. The dealer replaced the rear main seal; however, the failure recurred. The vehicle was taken back to the dealer, and the dealer replaced the rear main seal a second time; however, the failure recurred with engine oil leaking onto the ground. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 11,340.

Right front wheel control Arm broke on the interstate running 70mph with no control.

The passenger door is attached properly, when the truck reach 70 mph or higher and little cross wind, there is really loud noise like the brakes sticking. I was afraid the door might flew off while I'm driving and I have infant in the back. I took the truck in to the dealership where I purchased and the problem was never fixed. when I took the truck back the 2nd time, the dealership told me to take my truck to GM dealership. I took the truck to the GM dealership hour later my truck was ready, apparently this problem happened to another vehicle. Now the noise is worst and it's on both side when I'm driving 70mph or higher with cross wind. I took the truck back to the dealership and now I'm waiting on parts to arrive 2 weeks later no call back. It's been one year 6 months with less than 19000 miles, afraid the doors might pop off and still the problem is not fixed.

Vehicle developed a sensation at approximately 28,000 miles similar to driving over a rumble strip. At approximately 32,000 miles this was diagnosed as a failing torque convertor. There are TSBs related to this for the 8 speed transmission, but dealer stated no known TSBs exist for the 6 speed. The truck is currently in the shop getting the torque convertor replaced and should be available for pick-up in the upcoming week. Rumble strip sensation occurred under light throttle acceleration and presented more frequently on an incline. There were occurrences on flat ground, but this was not as common. The vibration occurred most often at highway speeds of around 70 MPH, but also occurred several times in the ranges of 20-30 and 40-50 MPH. Tachometer reading during these occurrences was around 1,500 - 2,000 RPM. Issue was intermittent and would come and go. Most of the time the sensation was mild, but periodically the vibration would be severe enough the driver felt like he had been rear-ended. A separate symptom would occur while going up hills and the tachometer would bounce up and down approximately 300 RPMs with a noticeable surging sensation. When presenting, the vehicle would surge forward every few seconds until the hill had been crested. This only occurred at highway speeds with cruise set and would not present when the rumble strip vibration was present.

I was driving down I27 10 miles south of Lubbock when my 2020 Silverado 1500 3.0 Diesel engine stopped accelerating. I was going 75 miles per hour and the truck just stopped causing trauma for me and my family we were lucky enough to get to the side of the road. I ended up calling gm roadside assistance and they sent a tow truck to pick us and the truck up. The truck wouldn't engage into drive nor reverse. Once towed to the dealership, Gene Messer Chevrolet, in Lubbock, Texas, a service tech mentioned that a ton of the lifters bending push rods are going out on the late 2019, 2020 model silverado due to cheaper lifters added to the vehicles due to Covid shortage supplies. In essence, they wanted to get these models out with no regard to safety of the consumer. I'm not pleased with the craftsmanship GM has lined out on these trucks, this could've ended way worst. They jeopardized my families safety for profits. Right now the truck is still awaiting diagnostics still won't drive nor reverse per dealer service tech. It's just a terrible situation, the truck is new only has 25,500 miles on it, this needs to be recalled.

After putting my vehicle in reverse, my backup camera did not come on and gave a warning that the camera was not working.

I hit a tree and air bags did not deploy nor did the seat belt lock. Broken 8 ribs, broke my nose, cut my face and had a collapsed lung.

Upon starting the vehicle for the second time one day, when placing the automatic transmission into 'D' - Drive, it began to roll backwards as if it was in Neutral on a slight decline and the brakes had to be applied to avoid rolling downhill backwards. After attempting to place it back into 'P' - Park and back into 'D' - Drive and attempting to try 'R' Reverse to try to get it to move forward properly, it would not go forward. After several tries and restarting the vehicle completely, it finally attempted to move forward but would only do so at a reduced speed and would not respond to the accelerator pedal beyond a certain amount. After trying again, it appeared to move forward a bit better, but then upon stopping at a stoplight and attempting to pull out for a left turn onto the road, the speed again was reduced and I had to immediately place it into 'R' - Reverse to avoid an accident due to oncoming traffic. Finally I was able to get it to move forward a bit better and was heading directly for the dealership but since the power just was not getting to the wheels (transmission?) I pulled over and shut off the truck for a few minutes. Upon starting the truck again, it seemed to move forward better after that but had the 'check engine light' illuminated. The truck is at the dealership now, they have had it nearly a week and said they will not begin to look at it for another week at least since they only have 2 technicians who can look at it.

It seems the top suspension arm on my front passenger side broke.

My 2020 Trail Boss recently had a break fail on the front right. The brakes are metal to metal and the brake sensor is reading 54% brake life left. GM says that there is only one brake sensor on the front of the truck and its on the right hand side. When I spoke to Chevy customer service I was told they have received several calls regarding this matter. Chevy service department is saying there is nothing wrong with any of the equipment, but I find it hard to believe that brakes wear this way normally. If they did I would think Chevy would have 2 brake sensors for each wheel.

The infotainment screen brightness is set too high, such that turning the brightness setting down enough for the infotainment screen to not be too bright turns the backlighting on the instrument cluster down to where it's almost unreadable. In this specific case I was trying to use Apple Maps through Carplay for navigation in an unfamiliar rural area, where lighting on the roads is almost inexistent besides in towns. During the day it's not too much of an issue, but any time between dusk and dawn one must make a choice between visibility out the windshield and being able to quickly read anything on the instrument cluster. It is my opinion that this issue is enough of a safety hazard to force GM to make changes, but unfortunately isn't the most egregious "feature" of this screen. That title belongs to what happens when you put the vehicle in reverse at night. It seems whoever designed it thought the view of the backup camera on the infotainment screen is the only thing you should be able to see, since it changes the brightness back to its daytime setting. This makes seeing out of the vehicle in any direction where the screen is even slightly in your view almost impossible. It also means you must wait a second or two for your eyes to adjust if you want to, for example, look at the backup camera on the screen then look out the rear window. In my case, even looking out the rear window into a garage with a light on was difficult after looking at the backup camera view. Add to all of this any kind of vision issues like needing prescription glasses or contacts, and your eyes are constantly trying to adjust between being able to see what your next turn might be and being able to read any signage that may be present. Simply put, it seems GM took the idea of making the vehicle a rolling smart device to be the primary use, even above having the ability to see where you're going safely.

I was going shopping and noticed my check engine light flashing, it flashed around 20 times then turned off. When I got done shopping, I started up my truck to leave and I had no power steering and the dash had Service ESC on it and the traction control light was on, So I slowly started to drive home with no power steering I drove around one mile and stopped for a coffee. When I jumped back in the truck the power steering was working and all lights and messages were off Being Sunday (12-5-21) no dealer was open, the truck has around 34,000 miles on it This is not the first time the check engine light came on and the dealer checked the codes and it was clear I checked with my code reader and no codes either

I started my truck up and the dashboard warned me with service ESC and also Service Power Steering drive with care. Steering wheel was very hard to turn obviously no matter what way. I only got like 14,169 miles on the truck. I left it sitting for about 2 hrs. And it's supposedly back to normal. No lights some how.

Vehicle has approximately 15789 miles. Loud taking sound coming from engine began November 2, 2021 as I was on Highway. Dealer advises all 8 lifters and cam need replacement. My investigation reveals that this is a persistent problem with this type of vehicle and many reports have been made about this same issue throughout the USA. My service advisor advised me that they have already repaired several of the same vehicles for the same problem. Engine is defective and requesting a recall to release entire engine now that this engine will need major overhaul.

High Pressure fuel pump failed external fuel leaking onto exhaust of truck. Lucky the truck didn't catch on fire. Would have if I kept driving. What component or system failed or malfunctioned, and is it available for inspection upon request? High Pressure fuel pump (external leak) under GM warranty they have the parts. Flannery Chevrolet Bad Axe MI How was your safety or the safety of others put at risk? Gas leaking on Hot catalytic converter and cross over pipe. Skid plate was full of fuel. A fire under the truck would have made it very difficult to get out of the vehicle once stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? Towed vehicle to dealership and they diagnosed High Pressure fuel pump leaking. they replaced the pump and appears to he resolved now. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not that I know of. GM warranty covered repairs. Vehicle only has 13, 720 miles on it. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Driving down the road started to notice a really bad fuel smell and after stopped you could hear the fuel hissing as it dripped on exhaust pipe. Vehicle sat for 10 mins and had puddle of gas under the front of the transmission. Start the engine again and it continued to drip. I Called towing to come get it.

Whine sound possible torque converter does not go away. Surging or delay in switching into second gear upon first start up and put in drive.

While towing at a GCWR of over 29,000 pounds, my truck displayed the “check trailer wiring“ message on the DIC. I’m glad that my vehicle alerted me to a situation with the trailer wiring, however, when this message is displayed it completely shuts off the brake output to the trailer brakes. It was incredibly nerve-racking and quite dangerous when traveling 70 mph down the freeway and then suddenly hitting traffic and realizing I had zero trailer brakes to assist me in stopping to avoid an accident. Once I was able to return home, I pulled the breakaway pin on the trailer and all brakes worked perfectly fine. I then pulled all the hubs on the trailer axles and found one brake magnet had wore down to the coil. Obviously this is an issue and needs to be replaced, but the fact that my truck cut break output to all the brakes completely is very dangerous and unacceptable. This is a serious safety issue since there is nothing that can be done while on the road to fix this. If I had been traveling in the mountains as I will be next week, this could easily have caused a much more serious situation. This situation has been discussed among other owners of the same vehicle who experienced the same situation. There is a message that comes up on the DIC, but at that point it’s too late since the trailer brakes are already turned off by the vehicle. It seems to me that unless there is a serious short or the truck senses and extremely high amperage overload that it should continue work and send brake power to a trailer even if there is one single component that fails. That is the way that brake controllers have worked since they were invented, and now this new “Integrated Trailer Brake Controller” is much less safe.

At 11,000 miles my car began to wobble dangerously. I took it to the dealership and they informed me that two Pins were missing from the alignment cams. They blamed Goodyear for not doing a good alignment at 3,000 miles. Goodyear says they see a lot of these issues in their shop and believes GM needs to recall and fix this issue on all of its models. The repair cost me $459.69. GM said this was not covered under warranty, since someone else did the alignment. This doesn't see fair and I think the government needs to look into this.

- My back up camera developed a fish eye distortion. - It makes it hard to see how close something is behind you, making it dangerous backing up with children in the area. - Yes, although the dealer is trying to claim it is ''normal'', even though it was not that way when I bought the truck, or I would not have purchased it. - There were no warning lamps or other symptoms prior to the problem. It appeared before 2,500 miles were on my vehicle.

The contact owned a 2020 Chevrolet Silverado 2500. The contact stated the seat heater was disengaged but failed to respond, causing the seat to remain hot. There were no warning lights illuminated. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The contact stated the failure had been reoccurring. The contact stated while the vehicle was parked and running, she heard an abnormal popping sound coming from the vehicle, as she turned around, she noticed smoke coming out of the vehicle. The contact stated a fire had started underneath the driver seat and she was able to extinguish it with the assistance of emergency units. The contact stated she sustained mild burns on her hands and arms but did not seek medical assistance. A police report was not filed. The vehicle was towed to a tow lot, where it was totaled. The dealer was notified of the failure. The manufacturer was notified of the failure and did not provide any assistance. The approximate failure mileage was 5000.

Esc light comes on brake systems failure max speed 62 mph and tralier brake systems. Abs light , engine light, traction light all come on

While driving home in my neighbor I was approaching vehicle ahead of me which was stopped. I applied the break pedal which went loosely all the way to ground and unresponsive. Due to my inability to stop on time I rear ended the vehicle. No warning that there was an issue with my breaks what so ever. The only thing that I did have going on was my trucks front panel (gauges & stereo screen) weren't functioning. I went to turn on my pick up and it behaved as if battery was dead. I let it sit for a few minutes and attempted to start it once again and it started right up. The issue was the stereo screen stayed black and only the fuel gauge and speedometer were functioning. In the end I ended up being at fault in the accident and reported it to my insurance.

275/60r20 Rear Passenger side exploded, damaging my rim. Less than 20k miles on truck.

The radio continuously keeps blacking out turning off and back on over and over. Radio has been replaced and everything and it’s still an issue.

After a morning’s fishing, I drove the boat to the launch site to retrieve and load onto the trailer. Started my 2020 1500 Silverado in the parking lot and went about 75 feet to the launch and retrieved the boat. While I was retrieving the boat, I left the Silverado motor running. After boat pickup, drove about 75 feet in the lot to rig the boat for travel and shut off the Silverado engine. After rigging was completed, started the truck and there was no power steering. The following two messages were present on the DIC: “service power steering drive with care” and “service ESC”. I can’t believe that this truck with less than 2800 miles was exhibiting such a major problem. Restarting the tuck multiple times did not clear the error messages. Since I live about three miles from the lake, I decided to take a chance and drove home and left the truck in the street. Called the dealer and made a service appointment. After about an hour, I went out and started the truck in an attempt to park it in the driveway. The messages had disappeared and power steering was functional. Also, I did some searching on the internet and found many other owners of 2020 1500 Silverado that had the exact same loss of power steering and messages that I had experienced. The dealer informed me that although there were many communication error codes present, they were not able to find the cause of the problem. They requested that I leave the truck with them and they will try to reproduce the power steering failure. The dealer didn’t seem to care, even after I mentioned that there were many others with identical problems and surely someone in Chevrolet engineering knows of the problem and how to fix it. Their response was that they were not aware of any known documented problems like mine. I think I’m getting the run around. They still have the truck after twelve days and no solution. My wife refuses to drive the 2020 1500 Silverado with such an unsafe condition.

Service ESC and Parking Brake error. Drove to work with no issues. Started up to drive home and I kept hearing a "Ping" noise like hail hitting my roof. Then I thought my transmission was going out while driving. It is almost like it is firing out of order. Dealership ordered multiple parts: Misfire in cylinder 4 plus issue with the heads and push rod. GM decided that the issue it to be repaired rather than a new engine be put in.

Momentary loss of electrical power going over bumps, stabilitrak warning then complete loss of cabin power, engine power and power steering. Corrects after approx 1 sec.

While driving all warnings lights came on and all gage needles started moving back and forth.

Popping sound and hard shifting during low RPM between low gears.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving 10 mph, the vehicle drove through a puddle of water, shuddered and jerked then loss motive power. The contact was not able to restart the vehicle. The contact had the vehicle towed to a local dealer who inspected the vehicle and diagnosed the failure as water entering the engine, and that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 21,400.

Service ESC and Service Parking Brake error. This was followed by loud pinging noises from the engine. Sounds like a misfire and knocking heads or valves.

Driving 50mph and the truck starts bucking, backfiring, and missing. Code appeared on the dash stating service ESC. Lack of Power steering and braking I parked the truck.

At least 3 times while driving the entire radio and information system has shut down while driving and completely gone black for 2-3 minutes and reset to factory reset This does not show as recall but worried that it may shut down vehicle completely Have told dealership during routine maintenance and they said they find no problem Obviously there is a reason this is happening

I was leaving work on May 17th and got in my 2020 Silverado and started the vehicle. Immediately codes were thrown on the dash stating that the power steering was out and that the ESC system needed serviced. The traction control system/ESC light was also illuminated on the dash. I was unable to turn the steering wheel whatsoever. I turned the vehicle off and restarted approximately three times all of which still were displaying the codes listed above. I let the truck sit for approximately 20 minutes and the codes had cleared themselves and the vehicle was functioning as it should. I immediately drove to the dealership and had it serviced. Dealership stated there was a programming issue related to the EBCM, which if I'm not mistaken was a recall already issued for the 2019 models. I have seen many instances online of this same issue occurring and sometimes impacting the ability to brake (if vehicle was in motion at time of onset). My onset occurred at approximately 14,000 miles while in park. Since the servicing (approximately 1 week) issue has not been replicated, but I am not sure if the problem has been fixed or if the computer is just functioning properly and will glitch again at some point in the future.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving approximately 40 MPH, the vehicle suddenly started to shake and misfire. The contact stated that the ESC warning and service parking brake warning lights were illuminated. The contact coasted to the side of the road and restarted the vehicle. The contact took the vehicle to the dealer who diagnosed that the electronic stability control module had performed an automatic reset as designed. After the reset, the misfire occurred. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 7,700.

MY TRUCK HAS ALREADY HAD A SHIMMY FEEL IN THE TRANSMISSION AROUND 60 MPH IT SHOOK AND WOULD SLIP GEARS. I JUST HAD IT GET WORSE THIS WEEK. I ALSO NOTICED THAT THE FRONT END IS NOT SHAKING REALLY BAD FROM 60-75 MPH ON NEWLY PAVED ROADS. THE TRUCK USED TO DRIVE LIKE A DREAM NOW ITS DRIVING SO ROUGH AND THERE IS SOMETHING GOING ON!

THE VEHICLE DOES NOT SHIFT INTO 4WD LOW RANGE. THE VEHICLE HAS BEEN TAKEN TO THE DEALER 4 TIMES TO CORRECT THE ISSUE BUT THE ISSUE STILL OCCURS.

INFOTAINMENT SYSTEM RANDOMLY SHUTS DOWN COMPLETELY(SCREEN TURNS OFF ALONG WITH ALL AUDIO AND CONNECTED DEVICES). ALSO THE USB PORT REFUSES TO CONNECT AND/OR RANDOMLY DISCONNECTS ITEMS ATTACHED TO IT. THIS HAPPENS WHILE THE VEHICLE IS STOPPED OR IN MOTION. IT HAS DONE IT ON THE HIGHWAYS, FREEWAYS, INTERSTATES, CITY STREETS, COUNTRY ROADS, DIRT TRAILS, MY WORKS PRIVATE PROPERTY, EVERYWHERE IN SHORT. HAPPENS ON HOT SUMMER DAYS AND COLD WINTER NIGHTS. ITS 100% RANDOM. CHEVY KNOWS OF THE ISSUE BUT HAS REFUSED TO FIX FOR MORE THAN A YEAR NOW.

I WAS INVOLVED IN AN ACCIDENT THAT INCLUDED A ROLE OVER AND THE AIR BAGS DID NOT DEPLOY. GM SENT OUT ENGINEERS TO INVESTIGATE BUT SAID NOTHING WAS WRONG EVEN THOUGH THE AIR BAG MALFUNCTION LIGHT CAME ON DURING AND AFTER THE ACCIDENT. MY ROOF, WINDSHIELD WAS CAVED IN AND MY FRONT END TOOK HEAVY DAMAGE. ALL FOUR TIRES WERE BLOWN AND THEY SAID NOTHING WAS WRONG WITH THE AIR BAG SYSTEM. ONSTAR REPORTED THE AIR BAG ISSUE TO ME THROUGH EMAIL AS WELL.

MICHELIN TIRE EXPLODED WHILE DRIVING ON A HIGHWAY APPROXIMATELY 30 MPH, NO PROBLEMS BEFORE. ONLY 14,500 MILES DRIVEN

VEHICLE BOUGHT NEW FROM DEALER DEC 2020. I DECIDED TO REPLACE SOME LIGHTS SO, I LOWERED THE SPARE TIRE FOR BETTER ACCESS WHILE REPLACING A LIGHT BULB. I NOTICED EVERYWHERE THE SPARE TIRE AND THE FRAME CROSS MEMBERS COME INTO CONTACT THE PAINT HAS RUBBED AWAY AND RUST HAS BEGUN TO FORM. ALSO, THE SIDEWALL OF THE SPARE TIRE HAS CORRESPONDING SPOTS WHERE THE RUBBER HAS WORN AWAY. THIS LEADS ME TO HAVE CONCERNS AS TO THE SPARE TIRE'S AVAILABILITY IN THE EVENT OF A FLAT.

THE ENGINE LIGHT HAS COME ON 3 TIMES WITH A TRUCK WITH ONLY 9000 MILES ON IT I TOOK IT TO THE DEALERSHIP WHO GAVE ME A CODE OF P12A6 THEY TOLD ME CHEVROLET IS AWARE OF THIS PROBLEM BUT HAS NOT COME UP WITH SOLUTION YET OR EVEN WROTE A PROGRAM TO REFLASH THE COMPUTER. NOW I HAVE A PAPER WEIGHT IN MY DRIVEWAY AND BEING THAT I LIVE IN A DUAL TOWN TRYING TO FIND A DEALERSHIP THAT WILL FIX IT AND PROVIDE RENTAL CAR OR TRUCK. THIS DEFECT CAN BE MULTIPLE REASONS WITH THE ENGINE HARNESS WIRES CHAFFING OR TORQUE CONVERTER OR TRANSMISSION PLUS THE WHOLE ELECTRICAL SYSTEM NOT CRANKING OVER THE TRUCK FROM WHAT I WAS TOLD LAST TIME. NOW I'M WAITING TILL 730 TO CALL A DEALERSHIP SEE IF THEY HAVE A ROLL TRUCK TO PICK IT UP AND GET IT TO A DEALERSHIP WHERE THEY CAN TRY TO FIX THIS PROBLEM.

2020 SILVERADO 1500 DURAMAX. TORQUE CONVERTER FAILED WITH 6700 MILES ON NEW LEASED VEHICLE. ORIGINALLY BEGAN HAVING TRANSMISSION ISSUES IN NOV 2020 WITH SURGING WHILE STOPPED IN COLD WEATHER. DEALER RESEATED ALL CONNECTIONS. BEGAN TO HAVE LOUD WHINING WHEN SHIFTING. TOOK BACK TO DEALER AND INFORMED IT IS TURBO WHINE. NOT CONVINCED. MARCH 2021 BEGAN SURGING AGAIN. RETURNED TO DEALER AND KEPT FOR WEEK. MECHANIC STATED COULD NOT PRODUCE PROBLEM. AS I DROVE TO THE MAIN STREET AT DEALERSHIP BEGAN SURGING. RETURNED TO SERVICE, MGR GOES WITH ME AND CONFIRMS ISSUES WITH WHINE AND SURGE. BACK IN THE SHOP. THAT WAS 22 MARCH AND AS OF 8 APRIL; TORQUE CONVERTER FAILURE AND ORDERED NEW BELL HOUSING. GOING ON 4 WEEKS WITHOUT TRUCK.

MY LIGHTS IN THE DASH INSIDE THE TRUCK. GO FROM BRIGHT, TO DARK BLACK ALL THE TIME SINCE APRIL 2020. MY 4 WHEEL DRIVE ENGAGE, WONT WORK. 12/12/2020 IN THE SNOW TRYING TO DRIVE HOME

THIS TRUCK HAS 2700 MILES ON IT. GOT IN TO DRIVE IT HOME FROM THE STORE TODAY AND THE SERVICE ENGINE LIGHT IS ON. SAYS STABILITRAK ERROR AND ANTILOCK BRAKE ERROR. BRAKE PEDAL FELT STRANGE SO I WAS AFRAID TO DRIVE IT AFTER READING SIMILAR STORIES ABOUT TRUCKS VEERING OR NOT BRAKING WHEN THE PEDAL IS DEPRESSED. CALLED DEALER TO SCHEDULE SERVICE. THIS TRUCK HASN'T EVEN HAD ITS FIRST OIL CHANGE YET AND ALREADY HAVING ELECTRICAL PROBLEMS.

LOSS OF STEERING . I STARTED TRUCK AND PUT IN DRIVE AS I WAS TRYING TO DRIVE FORWARD I REALIZED THE STEER WHEEL WOULD NOT TURN AT ALL. I LOOKED DOWN TO SEE LIGHTS ON THE DASHBOARD SERVICE ESC AND SOMETHING ABOUT LOSS OF STEERING ON THE INFO SCREEN. I CANT BELIEVE THIS TRUCK IS NOT EVEN A YEAR OLD HAVE AN ISSUE LIKE THIS. I AM LUCKY I WASN'T AT HIGHWAY SPEEDS OR IN TRAFFIC AND JUST IN MY DRIVEWAY. I TURNED TRUCK OFF AND RESTARTED IT AND IT SEEMS AS NOTHING HAPPENED . EVERYTHING IS NORMAL AND NO LIGHTS ON. I TELL YOU I AM VERY SCARED AND WORRIED TO DRIVE THIS VEHICLE AND CANNOT BELIEVE THIS HAS BEEN OVERLOOKED BY GM AND THE NHTSA SINCE I HAVE SEEN AND HEARD MULTIPLE COMPLAINTS ABOUT THIS.

BATTERY KEEPS DISCHARGING. MAKING SURE NO LIGHTS LEFT ON IN VEHICLE. TOTALLY DRAINED BATTERY IN JUST 3-4 DAYS WITHOUT CRANKING OR MOVING. AFTER RECHARGE CRANKED NORMALLY

THIS TRUCK DOESN'T EVEN HAVE 7500 MILES ON IT. IT WAS DRIVEN TO WORK THIS MORNING WITHOUT ISSUE AND PARKED FOR APPROXIMATELY FOUR HOURS. UPON ATTEMPTING TO START IT FOR LUNCH HOUR THREE MESSAGES SHOWED UP IN THE DIC: 1) 'SERVICE ESC', 2) 'SERVICE POWER STEERING', AND 3) 'PARK ASSIST OFF'. IN AN ATTEMPT TO EVALUATE I PULLED THE TRUCK FORWARD AND THE AVAILABLE STEERING REFLECTED AN INOPERABLE POWER STEERING SYSTEM. I BACKED INTO THE SPOT AGAIN AND SHUT THE TRUCK DOWN. I STARTED THE TRUCK AND SHUT IT DOWN FOUR OR FIVE MORE TIMES WITH THE SAME MESSAGES PRESENTED (ALTHOUGH PARK ASSIST STOPPED APPEARING) AND ONLY ON THE LAST TIME DID THE MESSAGES GO AWAY AND POWER STEERING RETURNED.

ONE OF THE COOLANT HOSES RUBS UP AGAINST THE CRANKSHAFT CAUSING HOSE TO BUST AND LEAK REDUCED ENGINE POWER LIGHT COMES ON AND CHECK ENGINE LIGHT CHEVY HAD TO USE A DIFFERENT HOES TO NOT RUB AGAINST THE CRANKSHAFT

FRAME PAINT PEELING OFF WITHIN 6 MONTHS. DRIVERS AND PASSENGER SIDE FRAME ABOVE REAR AXLES. MULTIPLE COMPLAINTS DOCUMENTED ON CHEVY FORUMS. PAINT FALLS OF WITH SIMPLE WASH EXPOSING BARE METAL FRAME WHICH WILL LEAD TO PREMATURE RUST AND CORROSION

REAR PASSENGER PILLAR LEAKING AND CAUSING RUST, STAINING OF HEADLINER AND PILLAR COVERS. DOCUMENTED BY MANY OWNERS ON CHEVY FORUMS. LEAK MAY BE FROM ROOF SEAL OR REAR WINDOW.

MY TRUCK IS ONLY A YEAR OLD AND ONE MORNING I WAS REVERSING OUT OF DRIVEWAY AND BACK UP CAMERA STOPPED WORKING

MY WIFE GOT INTO AN ACCIDENT WHERE SHE REAR ENDED FORD FIESTA AND HIT IT SO HARD THAT VEHICLE PUSHED A 2006 DODGE FULL SIZE PICKUP 100 FEET DOWN THE STREET AND THE AIRBAGS DIDN'T DEPLOY

BACKUP CAMERA ONLY IS FUNCTIONAL IN PERFECT WEATHER CONDITIONS. IF IT'S DARK WITH NO LIGHT, THE CAMERA HAS RESOLUTION SIMILAR TO A 1950 TUBE TV. IF IT'S RAINY OR CLOUDY, THE BACKUP CAMERA IS NOT FUNCTIONAL EITHER. THERE ARE NUMEROUS YELLOW LINES AND EXTREMELY POOR QUALITY PICTURE IN MANY OTHER CONDITIONS TOO. CHEVY HAS NOT DONE ANYTHING TO FIX THIS ISSUE IN MY TRUCK. THE VISIBILITY IS SO BAD I HIT MY TRAILER HITCH ON THE BUMPER 7' OFF OF MY HITCH LOCATION. I COULDN'T SEE THAT MY TRAILER WAS THAT CLOSE TO ME ON THE SCREEN

MULTIPLE INSTANCES OF SERVICE ESC, SERVICE PARKING BRAKE AND CHECK ENGINE LIGHT COME ON. THE BRAKES ARE THEN AFFECTED AND ARE TOUGH TO PRESS CAUSING THE BRAKING TO BE SLOWED DOWN AND THE ABS KICKED ON WHILE IN MOTION.

2020 SILVERADO RST 1500 4X4 ALLSTAR WITH 8 SPEED TRANSMISSION. AT 4,000 MILES DEVELOPED A SHUTTER IN TRANSMISSION AND SLIPPING AND HARD SHIFTING MAINLY BETWEEN GEAR 1-2. BAD ENOUGH WHEN YOU START FROM A STOP WHEN IT SHIFTS YOU FALL FORWARD. THE ACCELERATION PUSHES YOU BACK AND THEN IT JUST SLIPS TO NO WHERE TILL IT CATCHES AND GOES. CONTACTED SHOP AND WAS TOLD AT 1ST OIL CHANGED THEY WOULD FLUSH THE FLUID PER THE SERVICE BULLETIN. THIS MADE IT WAY WORSE. SHIFTING IS MORE ROUGH AND SHUDDER IS MORE FREQUENT. TOOK IT BACK FOR THE 2ND TIME AND HAD TO DRIVE WITH A TECH SO THEY COULD EXPERIENCE THE ISSUE. IT IS GOING BACK TO THE SHOP TOMORROW 1/11/2020 WITH ONLY 7,500 MILES WITH HOPES OF A NEW TORQUE CONVERTER. THIS SHOULD BE A RECALL AND RESULT IN A CLASS ACTION. THIS ISSUE IS SO COMMON AND THIS TRUCK IS BRAND NEW. HAD IT IN SHOP WITH 2,000 MILES WITH AN OIL LEAK.

WHILE DRIVING AROUND 40 MPH AND HIGHER TRUCK SUFFERS EXTREME WIND NOISE WHICH THE DEALERSHIP DESCRIBES AS WIND TURBULENCE. TRUCK SOUNDS LIKE A WINDOW IS CRACKED OPEN WHILE DRIVING EVEN THOUGH ALL WINDOWS ARE ALL THE WAY UP.

THIS TRUCK IS 2 MONTHS OLD AND ONLY HAS 2300 MILES ON IT. ON SUNDAY 12/27, THE TRUCK WOULD NOT START. ALL DASH PANEL AND LIGHT INDICATOR WARNINGS CAME ON INCLUDING 4 WHEEL DRIVE ASSIST FAILURE, BRAKE SYSTEM FAILURE, TPS FAILURE, CHECK ENGINE, BATTERY ERROR, ETC. AFTER JUMP STARTING THE BATTERY, THE TRUCK TURNED ON BUT THE CHECK ENGINE LIGHT STAYED ON ALL DAY. ON MONDAY 12/28, THE TRUCK DID NOT START AGAIN HOWEVER, THIS TIME, NO INDICATOR LIGHTS, DASH PANEL OR ANYTHING CAME ON AND I WAS ALSO UNABLE TO EVEN LOCK THE TRUCK. IT WAS TOWED TO THE DEALERSHIP AND AFTER 2 DAYS THEY STILL HAVE NOT FOUND THE PROBLEM WITH THE TRUCK ALTHOUGH THEY HAVE INDICATED THERE IS A CLEAR PROBLEM. THE TRUCK IS STILL CURRENTLY AT THE DEALERSHIP.

DROVE TO WORK NO ISSUES NO LIGHTS AFTER WORK I START THE TRUCK CHECK ENGINE LIGHT IS ON SERVICE EBRAKE LIGHT IS ON AND THE EBRAKE LIGHT IS FLASHING TRUCK WILL NOT MOVE EBRAKE IS STUCK ON AND I DID NOT SET THE BRAKE WHEN I PARKED

TL* THE CONTACT OWNS A 2020 CHEVROLET SILVERADO 1500. THE CONTACT STATED WHILE DRIVING 55 MPH DOWNHILL, THE VEHICLE INDEPENDENTLY SHIFTED INTO NEUTRAL WITH AN UNKNOWN WARNING LIGHT ILLUMINATED. THE CONTACT STATED THAT THE VEHICLE RESUMED NORMAL OPERATION AFTER THE VEHICLE WAS TURNED OFF AND RESTARTED. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO YOUNG BUICK GMC (325 OVERLAND AVE, BURLEY, ID 83318) TO BE DIAGNOSED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 21,000. ## VIN PASSED ## CHEVROLET 2020 SILVERADO ##

IN MAY I PURCHASES A 2020 SILVERADO. ON DECEMBER 05TH, 2020. I WAS DRIVING ON THE INTERSTATE HEADING HOME FROM MY SON'S FOOTBALL GAME . THE "SERVICE BRAKE SYSTEM" MESSAGE DISPLAYED ON THE VEHICLE'S DASHBOARD. BRAKING BECAME SLUGGISH AND STIFF. I INITIAL THOUGHT THE BRAKE FLUID HAD HAD LEAKED OUT. THE VEHICLE MAINTAINED POWER TO ALL OTHER SYSTEMS. ONCE HOME I CHECKED THE ENGINE BAY AND BRAKE CALIBERS AND FOUND THEM TO BE INTACT. AT THIS TIME THE VEHICLE HAS 12,400 MILES. AFTER A INITIAL ASSESSMENT, WAS INFORMED THAT IT WAS DETERMINED TO BE A "COMPUTER GLITCH" THAT WAS EFFECTING THE TRANSMISSION AND BRAKE SENSORS. THE BRAKE MODULE WAS REPLACED AND TRANSMISSION "SOFTWARE" WAS UPDATED. THIS WAS COMPLETED ON DECEMBER 09TH, 2020. UPON COMPLETION THE TECHS CONDUCTING A "DRIVE TEST", AT WHICH TIME THE WARNING APPEARED AGAIN. MY VEHICLE REMAINS AT THE SERVICE DEPARTMENT, WHILE THEY "TROUBLESHOOT" THE PROBLEM. DUE TO THE VAGUE RESPONSES BEING PROVIDED BY THE DEALERSHIP SERVICE STAFF AND THE LACK OF AN ESTIMATED TIME LINE FOR THE COMPLETION OF THE REPAIRS. I BELIEVE THERE IS A MUCH LARGER ISSUE THAT THEY DON'T WANT TO REVEAL.

DROVE TO SAMS CLUB AND RETURNED TO MY TRUCK AN HOUR LATER. TURNED ON THE TRUCK AND I HAD A SERVICE POWER STEERING MESSAGE, DRIVE WITH CARE WARNING AS WELL AS SERVICE ESC. IT WAS REALLY HARD TO TURN THE STEERING WHEEL. I TURNED OFF THE TRUCK AND PULLED OUT THE MANUAL. AFTER 5 MINUTES, I TURNED THE TRUCK ON AND NO CHANGE. I KEPT READING AND ABOUT 15 MINUTES LATER I TURNED ON THE TRUCK AGAIN AND THIS TIME THE STEERING WAS BACK TO NORMAL WITH NO DASH MESSAGES. I DROVE HOME AND SCHEDULED AN APPOINTMENT FOR 12/14/202 WITH MY DEALER, ANCIRA CHEVROLET, SAN ANTONIO, TEXAS. I READ ON THE INTERNET THAT OTHER SILVERADO OWNERS ARE HAVING THE SAME PROBLEM. MY TRUCK ONLY HAD 4,529 MILES WHEN THIS HAPPENED.

TRAVELING AT ABOUT 75-80MPH, ON A HIGHWAY, - BRAKES ENGAGED, SLOWING VEHICLE BY ABOUT 15MPH CAUSING THE TRUCK TO JERK AS IF IT MISSED A GEAR. "SERVICE ESC" DIAGLOGUE, TRACTION CONTROL LIGHT, AND CHECK ENGINE LIGHT CAME ON.

IM GETTING A HARD CLUNK SOUND WHEN SHIFTING INTO REVERSE. IT JUST STARTED HAPPENING AND ITS NOT FREQUENT ENOUGH TO TAKE IT IN TO REPLICATE.

MY NEW 2020 CHEVY SILVERADO TRAIL BOSS TRUCK BURNED DOWN IN MY FRONT YARD. I HAD DRIVEN IT THAT MORNING FOR A SHORT DURATION AND IT WAS OPERATING NORMAL. I ARRIVED HOME AROUND 1:30PM, PARKED IT AND AWOKE TO IT FULLY ENGULFED IN FLAMES JUST BEFORE MIDNIGHT. THE TRUCK HAD BEEN PARKED FOR APPROXIMATELY 10 HOURS BEFORE IT IGNITED.

WHEN ATTEMPTING TO START FROM A STOP AT AN INTERSECTION WHEN THE AUTO START/STOP FUNCTION HAS STOPPED THE ENGINE, THE VEHICLE WILL FREQUENTLY HESITATE TO START, THEN ONCE STARTED EXHIBITS UNUSUAL ENGINE/TRANSMISSION BEHAVIOR. THIS TRUCK IS NOW ON ITS FIFTH CHECK-ENGINE LIGHT SERVICE FOR IDENTICAL FAILURES OF THE AUTO START/STOP FUNCTION. THE GM ONSTAR DIAGNOSTICS REPORTS INDICATE 2 FAILURE MODES, ONE WITH THE ENGINE/TRANSMISSION AND THE OTHER WITH THE LITHIUM-ION BATTERY. I HAVE SEVERAL CONCERNS. 1, I MAY BE STRANDED AT AN INTERSECTION WITH A VEHICLE THAT WILL NOT RESTART AND/OR HAS STALLED IN THE INTERSECTION AND 2, THE LITHIUM-ION BATTERY WILL FAIL CATASTROPHICALLY LEADING TO A VEHICLE FIRE.

REPETITIVE FAULTS OF THE AUTO START/STOP SYSTEM. I HAVE NOTIFICATIONS ON THREE SEPARATE OCCASIONS WHILE DRIVING THE VEHICLE FROM THE ONSTART DIAGNOSTICS SERVICE OF TWO IDENTICAL FAULTS. ONE, A DEFECT WITH THE ENGINE & TRANSMISSION SYSTEM AND ONE A DEFECT WITH THE LITHIUM-ION BATTERY. TO DATE THERE HAS NOT BEEN AN EFFECTIVE REPAIR. THE LATEST ATTEMPT, REPLACING THE LITHIUM-ION BATTERY, SOMEHOW HAS FORCED THE SYSTEM TO NO LONGER FUNCTION UNDER ANY CONDITION. DRIVING CONDITIONS VARIED EACH TIME.

WHILLE SITTING AT A RED LIGHT, THE AUTOMATIC ENGINE STOP FEATURE ACTIVATED AND STOPPED THE ENGINE. WHEN I RELEASED THE BRAKE AND STEPPED ON THE GAS PEDDLE THE ENGINE DID NOT RESTART. THE VEHICLE HAD TO BE TOWED IN FOR REPAIR. THE DEALER MADE REPAIRS IN A SOMEWHAT TIMELY FASHION EXCEPT THAT THE PART HAD TO BE ORDERED FROM THE FACTORY AS NONE WERE AVAILABLE. WOULD HAVE THOUGHT A STARTER DESIGNED TO START AND STOP NUMEROUS TIMES A DAY WOULD HAVE LASTED JUST A WHILE LONGER?

THE 2019-2021 SILVERADO'S HAVE A MAJOR SAFETY ISSUE WITH THEIR REARVIEW CAMERAS AT NIGHT TIME. THE INFOTAINMENT SCREEN ON THESE VEHICLES DIMS APPROPRIATELY AT NIGHTTIME TO ENSURE SAFE VIEWING OUTSIDE OF THE VEHICLE, HOWEVER AT NIGHTTIME WITH THE INFOTAINMENT SCREEN DIMMED, WHEN SHIFTING INTO REVERSE THE SCREEN GOES TO FULL BRIGHTNESS AND MAKES VISIBILITY OUTSIDE OF THE VEHICLE ALMOST IMPOSSIBLE ON PARTIALLY LIT AREAS. THIS CAUSES SAFETY ISSUES AS YOU ARE NOT ABLE TO MAKE USE OF YOUR MIRRORS TO SEE OBSTRUCTIONS OR OBSTACLES. THIS IS FURTHER MAGNIFIED AS THE QUALITY OF THE REAR VIEW CAMERA AT NIGHT IS VERY POOR, SO THE POOR CAMERA QUALITY COUPLED WITH THE INABILITY TO EVEN USE THE VEHICLES MIRRORS TO SEE OUTSIDE CAUSES SAFETY ISSUES. MANY OTHERS HAVE COMPLAINED AND DOCUMENTED THIS SAME ISSUE AND HAVE RAISED CONCERNS WITH GM AND DEALERSHIPS TO NO AVAIL. THIS SHOULD BE AS SIMPLE AS A SOFTWARE UPDATE TO MAINTAIN SCREEN BRIGHTNESS WHEN SHIFTING INTO REVERSE DURING NIGHTTIME OR DARK CONDITIONS.

1ST OCCURRENCE, 9840 MILES- SLOWING TO STOP SIGN, ABOUT 10MPH, TRUCK JUMPED VIOLENTLY, FELT LIKE I WAS REAR-ENDED. SERVICE PARKING BRAKE, SERVICE ESC, TRACTION CONTROL OFF MESSAGES AND CEL ON. STUCK IN GEAR. RESTARTED TRUCK, RESUMED NORMAL OPERATION BUT CEL REMAINED. 2ND OCCURRENCE, 9865 MILES - 65MPH ON HIGHWAY GOING AROUND CURVE, TRUCK JUMPED VIOLENTLY CAUSING REAR END TO BREAK FREE SLIGHTLY, THOUGH I KEPT CONTROL. TRANSMISSION NOW SEVERAL GEARS LOWER AND STUCK THERE, TURNING 2400 RPM AT 65MPH. SAME THREE WARNING MESSAGES AND CEL. TRIED MANUAL TRANSMISSION MODE, BUT IT DISPLAYED NO GEAR INDICATION, AND THE +/- BUTTONS DID NOTHING. PULLED OFF HIGHWAY, RESTARTED, ALL MESSAGES WENT AWAY, CEL REMAINED. TRUCK RESUMED NORMAL OPERATION. 3RD OCCURRENCE, 9905 MILES (ON THE WAY TO THE DEALER) - I WAS STOPPED AT TRAFFIC LIGHT, FIRST IN A STRING OF CARS. LIGHT TURNED GREEN, I STARTED TO ACCELERATE, JUST INTO THE INTERSECTION, TRUCK JUMPED VIOLENTLY, SAME WARNING MESSAGES, STILL HAD THE CEL FROM THE LAST TIME. TRUCK WAS NOW STUCK IN A HIGHER GEAR, COULD BARELY GET THROUGH INTERSECTION. VEHICLE BEHIND ME NARROWLY MISSED REAR-ENDING ME, AND OTHERS WERE BLOWING HORNS AS I LIMPED TO THE FAR SIDE OF INTERSECTION. THIS IS A MASSIVE SAFETY CONCERN. IF ANY OF THE ABOVE SCENARIOS HAD OCCURRED ON SNOWY/ICY ROADS, I COULD HAVE INJURED OR KILLED SOMEONE, INCLUDING MYSELF AND/OR MY [XXX] YEAR-OLD. DEALER REPLACED TCM, BUT IS STILL NOTING "LOSS OF COMMUNICATION" CODES BEING GENERATED. A CHEVY ENGINEER HAS REQUESTED THEM TO INVESTIGATE THE WIRE HARNESS FOR DAMAGE IN A PARTICULAR LOCATION, SUGGESTING CHEVY KNOWS OF A MANUFACTURING ISSUE. IF THAT'S SO, AND CHEVY HASN'T ISSUED A RECALL - OR EVEN A TSB - THEN THIS POSES A STRONG CASE FOR NEGLIGENCE ON THEIR PART. ARE THEY WAITING FOR SOMEONE TO GET INJURED OR DIE BEFORE ACTING ON THIS? I'VE NOW BEEN WITHOUT THE TRUCK FOR 10 DAYS. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

RADIO AND DASHBOARD ELECTRONICS SHUTOFF COMPLETELY WHILE DRIVING AND THEN WILL COME BACK ON A MINUTE LATER! LOOSES ALL CONNECTIONS TO PHONE, MAPS, BLUETOOTH ETC...., THEN OUT OF THE BLUE TODAY THE AIRBAG LIGHT AND SERVICE SAFETY RESTRAINT SYSTEM WARNING CAME ON! THIS IS SO DANGEROUS AND IS GOING TO CAUSE ME TO HAVE A WRECK!

BACKUP CAMERA IS COMPLETELY WASHED OUT AT NIGHT AND DURING THE DAY IS FUZZY AND OUT OF FOCUS. DEALER SAYS THIS IS NORMAL. ITS A SAFETY ITS A SAFETY HAZARD TO ME.

THE TRUCK HAS ~3000 MILES. WHILE DRIVING THE TRUCK AT HIGHWAY SPEED (65 MPH), A WARNING CAME ON THE DASH "ENGINE POWER REDUCED", FOLLOWED BY A CHECK ENGINE LIGHT, AND THEN THERE WAS NO RESPONSE FROM THE THROTTLE/GAS PEDAL. THE ENGINE WAS STILL RUNNING, BUT NO POWER WAS AVAILABLE WHEN PUSHING ON THE GAS PEDAL. LUCKILY, I WAS ABLE TO PULL OFF OF THE HIGHWAY; HOWEVER, IF THIS WOULD HAVE HAPPENED CROSSING TRAFFIC OR ON A BUSY HIGHWAY, THE RESULTS COULD HAVE BEEN FATAL. I WAS SURPRISED AND SHOCKED TO SEE A NEW TRUCK PROVIDE ZERO POWER FROM THE GAS PEDAL. THIS IS A SIGNIFICANT RISK TO CONSUMERS, DRIVERS, AND OTHER CARS ON THE HIGHWAY. WHEN I PUT THE TRUCK ON A CODE READER, I RECEIVED THE CODE P26C0. THE LOCAL DEALERSHIP STATED THAT I AM NOT THE ONLY ONE EXPERIENCING THESE ISSUES WITH THE 3.0 DURAMAX DIESEL.

I HAVE A 2020 SILVERADO 1500 LT TRAIL BOSS WITH JUST OVER 5000 MILES ON IT WITH ONE PREVIOUS RECALL WHICH WAS COMPLETED. ON THIS OCCASION I WAS TRAVELING ON THE HIGHWAY AT ROUGHLY 65MPH WHEN ALERT SOUNDS CAME ON FOLLOWED BY A MESSAGE ON THE CLUSTER SAYING TO SHIFT THE VEHICLE TO NEUTRAL AND PUSH START BUTTON. I DID THAT AND THERE WAS NO RESPONSE. I WAS IN THE FAST LANE AND DID NOT HAVE ENOUGH SPEED TO GET TO SHOULDER SO I PULLED TO CENTER TURN LANE OF HIGHWAY TO STOP. I ATTEMPTED TO START THE VEHICLE SEVERAL TIMES OVER 5-10 MINUTES WITH NO RESPONSE. CLUSTER GAUGES WOULD CYCLE LIKE WHEN VEHICLE IS STARTED, BUT IT DID NOT ENGAGE THE STARTER. I ALSO TRIED TO REMOTE START FROM KEY FOB WITH SAME RESPONSE. THERE WAS TRAFFIC TRAVELING AT HIGH SPEED IN OPPOSING DIRECTION ON EITHER SIDE SO IT WAS UNSAFE TO INSPECT THE VEHICLE. I USED ONSTAR TO GET ROADSIDE ASSISTANCE AND ABOUT 15 MIN LATER POLICE SHOWED UP TO PROVIDE ASSISTANCE. ONSTAR SAID IT WOULD BE CLOSE TO AN HOUR FOR A TOW, BUT POLICE GOT ME ONE ABOUT 15 MINUTES LATER. LUCKILY TEXAS COPS ARE PRETTY COOL SO WE JUST HUNG OUT UNTIL TOW TRUCK ARRIVED.

HOLLOW VALVE STEM FAILURE. METAL SHARDS GOT INTO THE OIL & SEIZED UP THE MOTOR. WAS DRIVING 35MPH AT NIGHT ON A BUSY 2 LANE CITY STREET, NO SHOULDER. LESS THAN 1,200 MILES ON THE ENGINE

CHEVY SILVERADO 1500 - HAS A FEEL LIKE RUNNING OVER RUMBLE STRIPS AND GOES AWAY. OCCURS AT OR BETWEEN 60 AND 65 MPH. IT ISN'T CONTINUOUS AT ALL. DOESN'T DO IT AT LOWER SPEEDS OR HIGHER SPEEDS THAT I CAN FEEL. TRUCK WAS PURCHASED BRAND NEW IN 2020

WHEN PUTTING THE VEHICLE IN REVERSE WHEN ITS DARK THE BACK UP CAMERA COMES ON THE RADIO SCREEN. WHEN DOING SO THE BRIGHTNESS OF THE SCREEN CAUSES THE INABILITY FOR MY EYES TO ADJUST TIMELY. THIS BRIGHTNESS ALSO CAUSES MY INABILITY TO SAFELY USE MY SIDE MIRRORS BECAUSE OF THIS BLINDING EFFECT. THERE IS NO WAY TO DIM NOR TURN OFF THIS FEATURE. THIS HAS ALWAYS DONE THIS SINCE DELIVERY AND I'VE BEEN TO THE DEALER MULTIPLE TIMES FOR OTHER SOFTWARE UPDATES AND RECALLS. THIS STILL HASN'T BEEN ADDRESSED AND IS A MAJOR SAFETY CONCERN.

THE TRUCK IS NEW WITH 700 MILES. SEPTEMBER 26TH 2020 I CAME TO A STOP AT A LIGHT.AS I TOOK OFF THE TRUCK STARTED TO JERK AND THE CHECK ENGINE LIGHT CAME ON. I IMMEDIATELY DROVE IT HOME. AS I WAS DRIVING HOME WHILE IN MOTION THE TRUCK WOULD JERK WHEN IT WAS CHANGING GEARS. I RECEIVED A TEXT FROM GM THAT SAID TO HAVE THE ENGINE OR TRANSMISSION SERVICED WITHIN 7 DAYS. I DID NOT DRIVE IT UNTIL I WAS ABLE TO TAKE IT TO CHEVY. SEPTEMBER 28TH 2020 ON THE WAY THERE THE VEHICLE DID THE SAME THING. ON SEPTEMBER 30TH 2020 THE CHEVY TECHNICIAN SAID THE TRUCK WAS READY HE SAID THE PROBLEM WAS A TRANSMISSION CONTROL MODULE THAT WAS NOT PLACED CORRECTLY. I PICKED THE TRUCK UP OCTOBER 1ST 2020 AND DROVE IT STRAIGHT HOME JUST FINE. OCTOBER 2ND IN THE MORNING DRIVING TO WORK THE TRUCK STARTED TO JERK AGAIN AND THE CHECK ENGINE LIGHT CAME ON AND I RECEIVED ANOTHER TEXT FROM GM SAYING TO HAVE THE ENGINE OR TRANSMISSION SERVICED WITHIN 7 DAYS. ON THE WAY TO CHEVY I HAD TO STOP AT A LIGHT WHEN THE LIGHT CHANGED GREEN THE TRUCK DID NOT WANT TO TAKE OFF AND STARTED TO ROLL BACK AND I ALMOST HIT A VEHICLE. I PUT THE TRUCK IN PARK TURNED IT OFF RESTARTED IT THEN SAFELY DROVE IT TO CHEVY. TODAY IS OCTOBER 4TH AND I HAVEN'T HEARD ANYTHING FROM CHEVY I DID NOT BELIEVE THAT A TRANSMISSION CONTROL MODULE WOULD BE PLACED INCORRECTLY FROM THE FACTORY I BELIEVE THIS TRUCK HAS SOME KIND OF DEFECT AND IS UNSAFE TO DRIVE UNTIL CHEVY FIGURES OUT THE PROBLEM.

AFTER PARKING FOR ABOUT AN HOUR STARTED THE TRUCK AND GOT WARNINGS FOR SERVICE ESC AND SERVICE POWER STEERING, DRIVE WITH CAUTION. TURNED ENGINE OFF AND ON A FEW TIMES, NO CHANGE. CALLED ONSTAR, THEY SAID THEY COULD SEND ROADSIDE ASSISTANCE, I CHOSE NOT TO GET THE SERVICE AS WE WERE IN THE MIDDLE OF NOWHERE DOWN A SINGLE TRACK DIRT ROAD. DROVE HOME WITH NO POWER STEERING, TRACTION WARNING LIGHT ON THE WHOLE WAY. TURNED ENGINE OFF THEN ON AGAIN AND THE ISSUE WAS RESOLVED. IT LOOKS LIKE THERE HAVE BEEN SERVICE BULLETINS/RECALLS FOR SIMILAR ISSUES BUT NOTHING ACTIVE ON MY TRUCK WITH 2100 MILES. SOFTWARE/SENSOR PROBLEMS LIKE THIS CAN LEAD TO VERY DANGEROUS SITUATIONS. THANKS FOR THE WORK YOU DO AT NHTSA

2020 SILVERADO 1500 CUSTOM CREW CAB 4.6L, V6. PURCHASED TRUCK ONAUGUST 10, 2020. TOOK IT TO DEALER ON AUGUST 17, 2020 BECAUSE OF JERKING FORWARD AT LOW SPEED (20-25 MPH) AND REAR BRAKES MAKING A DEEP RUBBING SOUND. OF COURSE, TECHNICIAN SAID THERE WERE NO PROBLEMS (BECAUSE HE COULD NOT DUPLICATE) THE JERKING MOTION. AFTER PICKING UP MY TRUCK, I NOTICED THAT THEY DID NOT EVEN ADDRESS THE BRAKE ISSUE, NOR DID THE SERVICE ADVISOR NOTE IT ON THE FORM.

INOPERABLE INFOTAINMENT SYSTEM / BACKUP CAMERA / RADIO / ONSTAR. UPON STARTING VEHICLE, SCREEN STAYS BLACK AND NONE OF THE AFOREMENTIONED SYSTEMS WILL OPERATE.

THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE. THE CONTACT WAS REFERRED TO THE DEALER AND PROVIDED A CASE NUMBER. THE CONTACT WAS ALSO PROVIDED A CASE NUMBER. THE FAILURE MILEAGE WAS 13,900.

I WENT IN THE STORE THIS AFTERNOON, WHEN I RETURNED TO MY TRUCK AND STARTED IT UP I HAD A SERVICE POWER STEERING DRIVE WITH CARE WARNING AS WELL AS SERVICE ESC. I SHUT THE TRUCK OFF, WAITED A FEW MINUTES AND RESTARTED THE TRUCK, THE WARNING WAS STILL THERE SO I CALLED THE DEALER AND THEY SENT OUT A SERVICE TECH AND SERVICE MGR, THEY COULDN'T FIGURE IT OUT AND HAD IT TOWED TO BACK TO THE DEALER THE TRUCK ONLY HAS 1400 MILES ON IT

WAS ON VACATION AND WENT TO EAT SUPPER APPROXIMATELY AN HOUR LATER RETURNED TO VEHICLE CRANKED UP TRUCK AND WENT TO LEAVE (IN REVERSE) WHEN I CUT THE WHEEL THE TRUCK HAD NO POWER STEERING AND SO I PRESSED THE BRAKE AND IT WAS BARELY WORKING, LUCKILY I WASN'T GOING TO FAST AND WAS ABLE TO STOP BEFORE HITTING THE VEHICLE BEHIND ME. CHECK ESC LIGHT CAME ON. HAD TO DISCONNECT THE BATTERY TO RESET THE COMPUTER

THE FOLLOWING ALL TAKES PLACE WHILE DRIVING THE VEHICLE ON THE INTERSTATE AND CITY, AT HIGHER RATES OF SPEED AND WHEN TRAVELING AT A SLOWER SPEED - WHICH IS AN EXTREME DANGER - EVERY DASH WARNING LIGHT CAME ON AND WARNING MESSAGES FLASH (BRAKES, STEERING, TRAILER, FUEL, ETC) ROLL FROM MESSAGE TO MESSAGE, BRAKES GET SOFT AND HARD TO STOP, TRUCK TRIED TO STALL AND SLOWED DOWN LIKE IT WAS LOSING POWER (THIS HAPPENED WHILE ROLLING AT 45 MPH), AC STOPPED WORKING (FAN WORKING BUT COLD AIR STOPS), TRUCK LUNGED FORWARD WHILE ENGAGING THE BRAKES TO SLOW DOWN AT A RED LIGHT, STEERING DEFINITELY STIFFER DUE TO LACK OF POWER ASSIST. THESE SAME MESSAGES AND WARNING LIGHTS WILL ALSO CONTINUE TO FLASH WHEN THE TRUCK IS PARKED. THIS ISSUE STARTED AT 3300 MILES ON JULY 8TH, THEN IT HAPPENED AGAIN JULY 24TH, THEN AGAIN AUG 4TH/5TH.

TL* THE CONTACT OWNS A 2020 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT WHILE PULLING OUT OF THE DRIVEWAY AT APPROXIMATELY 5 MPH, THE BRAKE PEDAL WAS DEPRESSED AND WENT TO THE FLOORBOARD BEFORE STOPPING THE VEHICLE.

THE CONTACT STATED THAT THE POWER STEERING WAS TEMPORARY AND RETURNED TO NORMAL OPERATION. THE VEHICLE WAS TAKEN TO JOE BASIL CHEVROLET (5111 TRANSIT RD, DEPEW, NY 14043, (716)683-6800) TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE BRAKING SYSTEM NEEDED TO BE REPROGRAMMED. THE CONTACT WAS INFORMED THAT THE BRAKE FAILURE WAS RELATED TO NHTSA CAMPAIGN NUMBER: 20V116000 (SERVICE BRAKES, HYDRAULIC). THE RECALL REPAIR WAS PERFORMED. THE MECHANIC WAS UNABLE TO IDENTIFY THE CAUSE OF THE POWER STEERING FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 1,451.

STARTED THE ENGINE AND HAD NO POWER STEERING. I HAD A MESSAGE THAT SAID SERVICE ECS I BELIEVE. POWER STEERING HAS STARTED WORKING AGAIN SINCE.

WHEN I STOP SLOWLY THE BRAKE PEDAL STARTS TO MAKE A NOISE AND STARTS TO SHAKE. YOU CAN LITERALLY FEEL YOUR FOOT SHAKING WHEN STOPPING SLOWLY. IT DOES NOT MAKE IT EVERY TIME BUT WHEN IT DOES IT MAKES IT LIKE 4 TIMES. I FIRST NOTICED THIS WHEN DRIVING ON THE HIGHWAY WHILE ON A ROAD TRIP THEN IT STARTED DOING IT ON THE CITY STREET. IT DOES IT WHEN YOU ARE MAKING A STOP BUT HAVENT STOPPED COMPLETELY BECAUSE WHEN YOU COME TO A COMPLETE STOP IT STOPS DOING IT.

THIS VEHICLE WAS DELIVERED TO ME IN LATE MARCH 2020. NEW SMYRNA BEACH CHEVROLET SOLD ME TWO FAULTY VEHICLES. THE FIRST THEY TOOK BACK AND NOW THIS SECOND VEHICLES BACK UP CAMERA WORKS INTERMITTENTLY FROM DAY ONE. GM NOR THE DEALER SHIP CAN LOCATE THE REPLACEMENT PART AND THIS HAS BEEN ON-GOING FOR 3 MONTHS NOW. I DO NOT FEEL SAFE DRIVING A VEHICLE THAT HAS A FAULTY CAMERA. I FEAR THAT AS A RESULT, BODILY INJURY COULD RESULT TO SOMEONE ELSE. GM HAS FAILED TO GIVE ME AN ETA ON THE PART, FAILED TO PUT ME IN A LOANER VEHICLE, AND FAILED TO RESOLVE THE PROBLEM BY OFFERING ADEQUATE TRADE ASSISTANCE TO GET ME INTO A WORKING VEHICLE.

BRAKE SYSTEM FAILURE ON 2020 CHEVROLET SILVERADO 1500. MULTIPLE DASH WARNINGS NOTIFYING OF BRAKE FAILURE, ESC FAILURE, AND SERVICE BRAKE SYSTEM WARNING

DEAD BATTERY AT 1400 MILES... NO WARNINGS AND NO LIGHTS LEFT ON, NO EXCUSES!

I WAS PARKED AT A LOCAL LAKE WHEN I STARTED MY 2020 CHEY TRUCK AND NOTICED SEVERAL WARNINGS ON MY INSTRUMENT CLUSTER. BRAKE SYSTEM FAILURE, CHECK ENGINE LIGHT, SERVICE ESC & SERVICE TRAILER BRAKE. I BACKED UP SLOWLY AND NOTICE MY BRAKE PEDAL WAS HARD AND IT TOOK A LOT OF EFFORT TO GET IT TO STOP. THERE WAS A WARNING THAT SAID DRIVE NO FASTER THAN 43 MPH. THE TRUCK WOULD NOT EXCEED 43 MPH. I DROVE IT HOME ABOUT 3 MILES. WHEN I GOT HOME I TURNED OFF & RESTARTED THE TRUCK ALL ERROR CODES WERE GONE, BUT THE ENGINE LIGHT WAS STILL ON. THE BRAKES SEEM TO BE WORKING FINE, BUT I AM STILL TAKING IT TO THE DEALER MONDAY TO BE SAFE. I HAVE READ THAT THIS IS A COMMON PROBLEM AND SHOULD BE A RECALL, BUT I COULD NOT FIND ONE FOR MY VEHICLE. EVERYONE THAT OWNS ONE OF THESE TRUCKS SHOULD BE INFORMED ABOUT THIS ISSUE. IF PEOPLE ARE NOT AWARE OF THIS PROBLEM THERE WILL BE SOME SERIOUS ACCIDENTS BECAUSE OF THESE BRAKE FAILURES. NEVER THOUGHT I WOULD HAVE THIS PROBLEM FROM A CHEVY.

SERVICE BRAKE ASSIST SERVICE ESC *TR

I WAS STOPPED N THE DRIVE THRU AT IN-N-OUT WITH MY FOOT ON THE BRAKE AND THE ECO SYSTEM HAD TURNED OFF THE MOTOR. IT SPONTANEOUSLY TURNED BACK ON WITHOUT ME LIFTING MY FOOT OFF OF THE BRAKE AND THE TRANSMISSION ENGAGED AND THE TRUCK LAUNCHED FORWARD APPROXIMATELY 12-18 INCHES. THIS IS THE SECOND TIME THIS HAS HAPPENED TO ME. IT ALSO HAPPENED ONE NIGHT ABOUT 2 MONTHS AGO. THIS COULD HAVE BEEN VERY DANGEROUS, I COULD HAVE HIT SOMEONE OR THEIR CAR OR I COULD HAVE EVEN RECEIVED WHIPLASH MYSELF. *TR

THE INFOTAINMENT SYSTEM GOES TO MAX BRIGHTNESS AT NIGHT BLINDING THE DRIVER MAKING IT NEAR IMPOSSIBLE TO USE MIRRORS. THERE IS NO ADJUSTMENT TO CORRECT THIS. *TR

ON TWO SEPARATE OCCASIONS: ON THE HIGHWAY AT SPEEDS OF APPROX 50-70 MPH, THE POWER STEERING FEEDBACK WHILE MOVING THROUGH A LEFT CURVE FAILED. THE WHEEL DID NOT REACT BACK TO THE CENTER WHEN THE STEERING WHEEL WAS "LET GO". THE STEERING WHEEL FELT "DEAD" AND STAYED IN THE LEFT TURN POSITION. WHEN COMING OUT OF THE LEFT TURN/CURVE, THE WHEEL HAD TO BE FORCED BACK TO CENTER. PULLING OVER AND TURNING THE TRUCK OFF AND THEN ON, SEEMED TO FIX THE ISSUE TEMPORARILY. FEELS EXTREMELY UNSAFE. *TR

INFOTAINMENT SCREEN IS TOO BRIGHT FOR NIGHT DRIVING. NO DIMMER CONTROL. THE BACKUP CAMERA IS SO BRIGHT YOU CANNOT SEE OUT OF THE CAB. I ALMOST RAN INTO A TREE TYING TO BACK THIS THING UP AT NIGHT. DRIVING AT NIGHT, I WAS CONSTANTLY DISTRACTED BY THE BRIGHTNESS OF THE DISPLAY. YOU CAN TURN OFF THE DISPLAY, BUT IF YOU NEED NAVIGATION THAT DOESN'T WORK. YOU CAN DIM THE INTERIOR LIGHTS, BUT BY THEE TIME THE INFOTAINMENT SCREEN IS DIM ENOUGH YOU CAN NO LONGER SEE THE GAUGES. THE VEHICLE WAS IN MOTION. *TR

2020 SILVERADO LT WITH ONLY 4660 MILES WAS PARKED IN A NEIGHBORHOOD DRIVE WAY WHERE OUR 17 YEAR OLD SON HAD SPENT THE NIGHT WITH A FRIEND. HE STARTED THE TRUCK TO LEAVE AND IMMEDIATELY HAD SEVERAL ALARMS; BRAKE SYSTEM FAILURE, DRIVE NO FASTER THAN 62 MPH, SERVICE TRAILER BRAKE, SERVICE ESC. HE TRIED TO EASE OUT OF THE DRIVE TO TEST BRAKES, ABOUT 5-10 MPH; HE HAD NO BRAKES, ZERO BRAKES! HE ROLLED TO THE EDGE OF THE DRIVEWAY AND TURNED THE TRUCK OFF. AFTER ABOUT 5 MINS HE STARTED THE TRUCK AGAIN AND THE BRAKES WERE WORKING AND ALARMS WERE CLEARED BUT CHECK ENGINE LIGHT REMAINED ON. THIS WAS A VERY DANGEROUS SITUATION AND COULD HAVE LED TO MUCH WORSE ENDING. AFTER RESEARCHING ONLINE, WE FOUND THAT THIS IS VERY COMMON AND GM HAS DONE 2 RECALLS ON THIS PROBLEM YET IF YOU AREN'T AWARE OF IT, YOU, YOUR FAMILY OR OTHER INNOCENT DRIVERS COULD BE KILLED BECAUSE GM AND THE NHTSA HAVE NOT MOVED STRONGLY ENOUGH TO WARN OWNERS, THERE SHOULD BE A NATIONWIDE 'DO NOT DRIVE' ALERT ISSUED ON THESE VEHICLES. I HAVE CONTACTED MY ATTORNEY TO SEE HOW TO PROCEED AND OUR SON WILL NOT RISK HIS LIFE IN THIS TRUCK AGAIN. NO BRAKES AND NO EMERGENCY BRAKE!! WOULD GM'S CEO LET THEIR 17 YEAR OLD DRIVE THESE DANGEROUS TRUCKS? THE NHTSA NEEDS TO TAKE IMMEDIATE DIRE ACTION ON THIS, LOOK AT YOUR OWN WEBSITE AT HOW MANY COMPLAINTS THERE ARE ON THIS EXACT PROBLEM! MY ATTORNEY READ YOUR SITE AND HE SAYS YOU ALL CAN'T DENY KNOWING THE PROBLEM EXIST, TAKE ACTION BEFORE DRIVERS DIE. GM AND NHTSA ARE BEING NEGLIGENT ON THIS AND I WILL GLADLY TESTIFY IN ANY CLASS ACTION LAWSUIT AND UNFORTUNATELY THERE WILL BE SOME. GM SHOULD DO THE RIGHT THING AND IMMEDIATELY ADVISE ALL DRIVERS OF 2019-2020 CHEVY SILVERADOS TO STOP DRIVING THEIR NEW $40,000 TRUCKS AND CALL A LOCAL DEALER TO COME GET IT. DRIVERS WHO READ THIS PLEASE BE ADVISED, THIS IS VERY DANGEROUS AND SOME GM DRIVER WILL DIE BECAUSE OF THIS BRAKE FAILURE. *TR

I HAVE A 2020 SILVERADO 1500 THE BACK UP CAMERA IS SO BRIGHT AT NIGHT TIME (THE SCREEN BRIGHTNESS AND ITS WHITE WASHED/ TOO HIGH OF CONTRAST) THAT IT MAKES IT UNSAFE TO BACK UP AT NIGHT TIME. I AM BLINDED BY THE SCREEN AND CANT EVEN USE THE SCREEN. *TR

I PURCHASED THE VEHICLE AND 7 DAYS LATER IT WOULD NOT START AND THE BATTERY WAS COMPLETELY DEAD HAD TO BE TOWED TO THE DEALERSHIP. *TR

THIS IS MY SECOND COMPLIANT, ON 5/7/20, AFTER MY SHIFT ENDED. THE TRUCK WOULD NOT START. I CALL THE SALES PERSON, WE WENT OVER SEVERAL STEPS AND IT STILL WOULD NOT START. I CALLED ON STAR. SHE SAID WILL DO A DIAGNOSTIC. WHEN SHE STARTED EVERY THING WELL OUT. I CALL BACK BY PHONE AFTER AN HALF HOUR..THEY SENT ME A JUMPER. THE NEXT DAY I TAKEN IT TO THE DEALER. THEY RESET EVERY THING. SAID BEFORE I PURCHASED IT MAY HAVE SAT ON THE 6 MONTH. I HAD IT FOR WEEKS! ON 5/II/20, I TURNED THE ENGINE OFF GOT OUT AND LOCKED THE TRUCK. A FEW SECONDS CAME BACK AND UNLOCK TRUCK, OPEN THE DOOR THE RADIO WERE STILL ON. AFTER THAT IT CUT OFF. I WAS PARTED AT BJS. *TR

AT COLD START UP, THE TRUCK IMMEDIATELY ILLUMINATED THE CHECK ENGINE LIGHT WITH A MESSAGE OF REDUCED ENGINE POWER. A SHUT DOWN AND RESTART PRODUCED THE SAME RESULTS. SHUT THE TRUCK OFF AND PULLED THE TROUBLE CODE P26BB. NEXT START UP, CHECK ENGINE LIGHT WAS STILL ON, BUT THE REDUCED ENGINE POWER MESSAGE WAS GONE. DROVE IT TO THE DEALER WITH NO PROBLEMS, WHERE THEY DIAGNOSED A FAULTY COOLANT FLOW VALVE. 38 DAYS LATER IT STILL SITS AT THE DEALER STILL NOT REPAIRED. IF THIS PROBLEM WAS TO HAPPEN UNEXPECTEDLY WHILE DRIVING, REDUCED ENGINE POWER COULD PRODUCE DANGEROUS CONDITIONS IN CERTAIN SITUATIONS ( IE PULLING INTO TRAFFIC, MERGING). *TR

BRAND NEW TRUCK WITH ONLY 450 MILES. FIRST INCIDENT WAS CHECK ENGINE LIGHT CAME ON , BRAKE PEDAL WAS REALLY HARD TO PRESS ALMOST HIT CAR INFRONT OF ME. SECOND INCIDENT ALL LIGHTS CAME BACK UP ABS,SRS, TRAILER BRAKE MODULE, PARKING BRAKE, TRUCK WILL NOT GO FASTER THAN 42MPH. AND BRAKE PEDAL WAS REALLY HARD AGAIN. CALL ONSTAR FOR A DIAGNOSTIC AND CODE CAME UP, C05B0,P25A2. CHECK ENGINE LIKE CAME OFF. WENT TO DEALER TODAY AND THEY SAID NOTHING CAN BE DONE , BECAUSE NO LIGHT IS ON. SERVICE ADVISOR REFUSE TO PUT SCANNER TO READ ANY STORED CODE. SERVICE ADVISOR SAY IT CAN BE THE COMPUTER IS RESENTING, NEED TO KEEP DRIVING VEH UNTIL CHECK ENGINE LIGHT COMES BACK ON AGAIN. NO FEEL SAFE ON NEW VEH WITH NO BRAKES TWICE. *TR

WHEN DRIVING VEHICLE (OURS DOES NOT HAVE THE STOP START TECHNOLOGY); HOWEVER WHEN IDLING LOW OR COMING TO A STOP THE VEHICLE WILL JERK THEN DIE. THE MOTOR WILL COMPLETELY SHUT OFF; STALLING, THE ONLY WAY TO RESTART IS TO PUT THE VEHICLE IN NEUTRAL OR PARK AND TURN IGNITION AGAIN. THE MOTOR SHUTS OFF ENTIRELY USER IS UNABLE TO DRIVE; PRESENTS A HUGE SAFETY ISSUE. PUSHING GAS PETAL DOES NOT WORK EVEN IF IT DID HAVE THE STOP START TECHNOLOGY.

IT CUT OFF AT A STOP AND AFTER I STOP WITH WITH MY FOOT ON THE BRAKES. I FELL BUMP IN THE REAR OF THE TRUCK, LIKE I BEEN REAR END AND THE REAR SHAKES. SOME THE THE AS WELL. IT CUT OF AFTER I STOP A FEW SECONDS AND START RIGHT BACK UP. IN DRIVE WAY IDLES ABOUT 15 OR LONGER, IT CUTS OFF. I HAVE TO RESTART IT. AND TAKING OFF IN HESITATION AND SOME TIMES MOVEMENT IN THE REAR AND UNDER THE TRUCK. BOTH STATIONARY AND IN MOTION.

TRACTION CONTROL SYSTEM DISENGAGES WITH WHILE VEHICLE IS IN MOTION AND MULTIPLE WARNING LIGHTS ARE ACTIVATED. (TCS, CHECK ENGINE LIGHT, AND "ENGINE OPERATING AT REDUCED POWER" WHILE VEHICLE IS IN MOTION. THIS IS A NEW VEHICLE AND INCIDENT OCCURRED AT LESS THAN 300 MILES. THIS SEEMS TO OCCUR WHILE BRAKING: FIRST WHILE DRIVING IN TRAFFIC (TRAVELING AT <25MPH), THEN WHEN SLOWING ON APPROACH TO HIGHWAY OFF RAMP (TRAVELING AT <45MPH). *TR

THIS ISSUE HAS HAPPENED MULTIPLE TIMES, IN THE CITY, HIGHWAY, AND DEFINITELY WHILE I WAS IN MOTION. THIS HAS ALMOST CAUSED ME TO REAR END ANOTHER DRIVER. I GET A ABS WARNING AND MY SPEED IS LIMITED TO 62MPH. MY BRAKES ARE HARDER TO PRESS ON AND DOESN'T SLOW DOWN THE TRUCK NORMALLY. I GET A ABS SIGN, TRACTION CONTROL SIGN, AND A CHECK ENGINE SIGN. THE TRUCK IS ALMOST BRAND NEW WITH ONE PREVIOUS OWNER, AND ONLY 15K MILES. THIS ISSUE NEEDS TO BE RESOLVED, THIS IS UNACCEPTABLE. A TRUCK IS A LETHAL MACHINE AND IF I'M NOT ABLE TO STOP THE TRUCK HOW IT SHOULD BE STOPPED, I COULD POSSIBLY HURT OR KILL SOMEONE.

ON A VERY RAINY DAY I WAS DRIVING AROUND THE BLOCK I WENT THROUGH SEVERAL SMALL PUDDLES FROM RUN OFF SO NO MORE THAN TWO-THREE INCHES OF WATER. WITH A LOT OF RAIN AND SPLASHING FROM OTHER VEHICLES. MY TRUCK SPUTTERS AND DIES, NO DEEP WATER, NO OFF-ROADING. I WAS TOLD TODAY THAT THE TRUCK IS WATERLOCKED AND IT ISNT COVERED UNDER WARRANTY. I AM ASTOUNDED AS THIS WAS REGULAR DRIVING, HERE IS MY FACTORY LIFTED UP TRUCK WITH TONS OF CLEARANCE BROKE DOWN IN THE MIDDLE OF THE STREET AND LITTLE CARS PASSING ME BY DRIVING THE SAME ROAD I DID. THIS IS OBVIOUSLY A DESIGN FLAW OR SOMETHING AS I DON'T UNDERSTAND IF THIS TRUCK IS SO FRAGILE HOW COULD I EVER TAKE IT TO A BOAT RAMP. I BOUGHT A TRUCK TO USE AS A TRUCK.

ON THE HOOD OF TRUCK IS A CHROME "6.2L" EMBLEM. ON SUNNY DAYS AND DRIVING WEST THE SUN REFLECTS VERY BRIGHTLY OFF OF THE EMBLEM AND INTO THE DRIVERS EYES. EVEN WITH SUNGLASSES THE REFLECTION IS VERY BRIGHT AND PENETRATING.

THE BACKUP CAMERA BRIGHTNESS IS SO EXCESSIVE IT CREATES A HAZARD BACKING AT NIGHT NOT BEING ABLE TO SEE OUT PASSENGER SIDE MIRROR, NO BRIGHTNESS CONTROL FOR NIGHTTIME

RECENTLY PURCHASED VEHICLE WITH 1035 ODOMETER MILES. ON 3/6/20, BRAKES FAILED WHILE DRIVING ON A CITY STREET-PEDAL WENT SOFT TO THE FLOOR. WHEN VEHICLE WAS RESTARTED, A C/S CHECK ENGINE LIGHT WAS ILLUMINATED. DROVE DIRECTLY TO CHEVROLET DEALERSHIP FOR SERVICE. DID NOT RECEIVE NOTICE OF RECALL PRIOR TO THE BRAKE FAILURE. REPAIRING DEALERSHIP INDICATED THAT REPAIR WAS PERFORMED UNDER CHEVROLET'S CUSTOMER SATISFACTION PROGRAM. RECEIVED POSTCARD NOTIFICATION OF RECALL FROM PURCHASE DEALERSHIP ON 3/25/20.

IT HAPPENED AFTER DRIVING ON THE INTERSTATE, WE PULLED INTO A GAS STATION AND WHEN WE GOT BACK ON THE ROAD I FOUND THE LIST OF WARNINGS AND I LOST MOST ALL BRAKING AND POWER STEERING AND HAD A DASH FULL OF LIGHTS TELLING ME ALL SORTS OF WARNINGS. I PULLED OVER ON THE INTERSTATE ON-RAMP AND TURNED IT OFF AND BACK ON AND THE PROBLEM CONTINUED. 'SERVICE PARKING BRAKE' 'TRACTION CONTROL OFF' 'ENGINE POWER IS REDUCED' 'BRAKE SYSTEM FAILURE" 'SERVICE ESC' 'SERVICE TRAILER BRAKE SYSTEM' 'STEERING ASSIST IS REDUCED DRIVE WITH CARE' "SPEED LIMITED TO 43 MPH"

PURCHASED VEHICLE 2/20/20 LEFT BROKEN VEHICLE AT DEALER SAME DAY. DROVE APPROX 40 MILES NO ISSUES. THEN CHECK ENGINE LIGHT AND SERVICE BRAKE ASSIST MESSAGE APPEARED IN DRIVERS MESSAGE WINDOW, GOING APPROX 50MPH. RETURNED TO DEALER THEY RESET FAULT AND CLAIMED FAULT OR ISSUES WAS CAUSED BY SOFTWARE LOADING. REPORTED TRUCK AS GOOD. DEPARTED AND DROVE 2.5 MILES PARKED AT STORE THEN BACKED OUT OF PARKING SPOT AND FAULT AND SAME MESSAGE APPEARED AGAIN WHILE BACKING AT 2 MPH. RETURNED TO DEALER THEY HAVE TRUCK IN THEIR POSSESSION. GAVE ME NEW TRUCK TO DRIVE HOME. AFTER RETURNING HOME SEARCHED FOR ISSUE AND FOUND THIS HAS BEEN A 3 MODEL YEAR ISSUE. CHEVROLET NEEDS TO BE HELD RESPONSIBLE AND NOT BE ALLOWING TO SELL PRODUCTS WITH THE BRAKING SAFETY DEFECTS.

PUT TRUCK INTO PARK AND SHUT OFF, STARTED TO GET OUT BUT TRUCK WAS STARTING TO ROLL, TRIED TO STOP IT, PUSHED ON BRAKES, NO EFFECT, KEPT ROLLING AND GAINED MOMENTUM TILL IT HIT OUR CABIN AND STOPPED. LENGTH WAS 200FT APPX OF ROLL. MESSAGE CENTER SAID " PRESS BRAKE TO START " WHICH I WAS DOING AS IT GAINED SPEED. ALSO DURING ROLL THERE WAS A RATCHETING SOUND ALL THE WAY DURING THE 200FT ROLL WHICH IN DESCRIBING IT TO DEALER I WAS TOLD PARKING PAWL MAY NOT HAVE ENGAGED PROPERLY CAUSING THAT SOUND. I WAS ABLE TO START VEHICLE AFTER IT HIT CABIN SO I COULD ROLL IT BACK AWAY FROM CABIN. STARTED TRUCK AFTER ACCIDENT, NO WARNING LIGHTS ON, BRAKES WORKED. IN RURAL AZ, ON OUR PROPERTY WHEN THIS HAPPENED. TAKING TO DEALER TOMORROW.

WHILE DRIVING SERVICE ESC MESSAGE AND SYSTEM BRAKE FAILURE MESSAGE ILLUMINATED ON CENTER CLUSTER DISPLAY, ATTEMPTED TO APPLY THE THE BRAKES AND PEDAL WENT TO THE FLOOR ALMOST ROLLED INTO A BUSY TO LANE ROAD IN THE CITY. RECEIVED AN ONSTAR MESSAGE IMMEDIATELY AS WELL, PUT TRUCK INTO PARK AND SHUT IT OFF AND REMOVED THE KEY AND OPENED THE DRIVER DOOR, THEN RESTARTED TRUCK PREVIOUS MESSAGES WERE GONE BUT CHECK ENGINE LIGHT WAS ON. TWO DAYS LATER AT THE DEALERSHIP THE CHECK ENGINE LIGHT WAS OFF.

LIGHTS ON INSTRUMENTS PANEL ON AND OFF,, GAS GAUGE NOT WORKING. MILES LEFT GOES UP AND DOWN WHEN TRUCK IS SITTING.

I WAS DRIVING DOWN THE ROAD, GAVE IT GAS TO GO AROUND A VEHICLE AND IT FELT LIKE THE VEHICLE SHUT DOWN. ESC CAUTION, CHECK ENGINE LIGHT, AND BRAKE WARNING/CAUTION ALL ILLUMINATED. VEHICLE BEGAN TO SLOW DOWN DRASTICALLY AND IF I HADN'T GOTTEN OFF THE ROAD QUICKLY I WOULD HAVE BEEN HIT. IF I HAD BEEN TURNING INTO TRAFFIC FROM A STOP AND THAT HAPPENED I WOULD HAVE BEEN HIT. PULLED THE VEHICLE OVER, TURNED IT COMPLETELY OFF, REMOVED THE KEY, RESTARTED THE VEHICLE AND EVERYTHING WENT AWAY EXCEPT THE CHECK ENGINE LIGHT. HEADED TO THE DEALERSHIP AND AGAIN I GAVE IT SOME GAS AND IT DID IT AGAIN. PULLED OVER, TURNED OFF/ON AND SAME RESULTS, EVERYTHING CLEARED BUT CHECK ENGINE LIGHT. IF THIS WERE TO HAPPEN ON THE INTERSTATE THIS COULD CAUSE A MAJOR INCIDENT. I WAS ON A CITY STREET ON BOTH OCCASIONS. I HAD TO NURSE THE GAS PEDAL RETURNING TO THE DEALERSHIP WHICH WAS ABOUT 7 MILES FROM THE INITIAL INCIDENT. THE VEHICLE IS A 2020 CHEVY SILVERADO 1500 WITH THE 2.7L TURBO ENGINE.

BRAKE SYSTEM FAILURE LIGHT, STEERING ASSIST REDUCED DRIVE NO FASTER THAN 62 MPH SERVICE TRAILER BRAKE, SERVICE ESC. BRAKES WENT TO THE FLOOR AND DID NOT WANT TO STOP.

BACKUP CAMERA FUZZY MORE AT NIGHT GM SAYS ITS THE THE LOW COST CAMERA BUT ITS A SAFETY ISSUE ITS TERRIBLE.

AFTER PARKING FOR ABOUT 20 MINUTES, STARTED THE TRUCK AND THE ABS BRAKE LIGHT CAME ON. A WARNING ON THE SCREEN SAID SOMETHING TO THE AFFECT...BRAKE ABOVE 62 MILES FAILURE. ENGINE LIGHT CAME ON. I STARTED DRIVING AND NOTICED NO BRAKE PRESSURE. PRESSED BRAKE HARD, ALL THE WAY, THEN TRUCK STARTED TO SLOW DOWN. LUCKILY THERE WAS NOTHING IN FRONT OF ME OR I WOULD HAVE HIT IT. I CHECKED FOR BREAK FLUID LEAK UNDER THE TRUCK, NO LEAKS. I OPENED THE HOOD, NO LEAKS NOTED. I TURNED OFF THE TRUCK. WAITED A MINUTE AND STARTED IT AGAIN. SAME THING...NO BREAKS. BREAK WARNING LIGHTS CAME ON AGAIN. I FINALLY CALLED A TOW TRUCK FOR REPAIR.

I WAS DRIVING DOWN THE INTERSTATE WHEN TRAFFIC BEGAN TO BUILD UP. AS I TRIED TO SLOW DOWN I NOTICED AN EXTENDED DELAY IN STOPPING. NO WARNING LIGHTS CAME ON AT THIS POINT AND I CONTINUED TO DRIVE. I THEN EXITED THE INTERSTATE AND STOPPED AT A LOCAL GROCERY STORE. I STARTED MY VEHICLE BACK UP AND BEGAN DRIVING TO SCHOOL. I WAS DRIVING AROUND 40 MPH AND IT WAS THEN THAT MY VEHICLE ALARM WENT OFF AND SCREEN ADVISED THAT MY BRAKES HAD FAILED. I COULD NOT STOP MY VEHICLE AND HAD NO BRAKES. I THEN PUSHED THE PEDAL ALL THE WAY TO THE FLOOR BOARD. MY TRUCK SLOWED ENOUGH FOR ME TO GET IT INTO MY SCHOOL'S PARKING LOT. I THEN ENGAGED THE EMERGENCY PARKING BREAK AND NOTIFIED ROADSIDE ASSISTANCE.

2020 SILVERADO 1500 DURAMAX 3.0 1200 MILES AND CHECK ENGINE LIGHT WITH CODES. I WAS 300 MILES FROM HOME SO GLAD IT MADE IT. TAKE TO DEALER AND THEY TELL ME I CANT DRIVE IT BECAUSE OF A FAILED MASTER CYLINDER ISSUE. PART IS ON UNKNOWN BACKORDER.

AFTER HAVING FOG LIGHTS PROGRAMED AT THE DEALER, LOST BRAKE ASSIST ON THE WAY HOME AT LAST LEFT TURN AND TRUCK TOOK LONGER TO STOP BEFORE THE TURN THEN NORMAL ON A CITY STREET SPEED ABOUT 45MPH, CHECK ENGINE LIGHT CAME ON CHECKED CODES AT HOME FOUND 4, P25A2 BRAKE SYSTEM CONTROL MODULE REQUESTED MIL ILLUMINATION U0101 LOST COMM WITH TCM, U0100 LOST COMM WITH ECM/PCM AND U0146 LOST COMM WITH GATEWAY A.
