Truck will hard shift and bang into gear while driving. This usually happens when slowing then starting up again. happens at all speeds on highway, so hard it lunges me forward. condition getting worse. random times my windshield wipers will just come on ( I do not have rain sensors) the switch is in the off position and wipers will just come on and I have to turn them on then turn them off to get them to stop.

When driving normally OR pulling a camper (same day), power steering seems to "stick" as I exit either a moderate RH or LH corner. I must apply extra effort to the steering wheel to straighten out, and that invariably leads to an over-correction and departure into either the shoulder or the opposite lane. Problem is not sensitive to speed or weather conditions. The symptoms are not necessarily worse when pulling a camper, but the consequences are much more drastic and losing control of the vehicle feels much more imminent than when driving just the truck. Because the problem comes and goes so quickly, I can be applying force to straighten the wheel when suddenly, no force is required and the truck veers either left or right. I see no warning lights, nor do I see any messages displayed. I have not yet had the opportunity to get the truck to a mechanic. I'm not confident that I can safely drive to a repair facility, as the steering is so unpredictable.

Hard shifting, Shuddering, clunking sound when shifting between drive and reverse. Was informed by Ken Ganley Chevy in Brookpark , Ohio that the valve body inside the 8speed transmission is faulty and is on a nationwide backorder.

The left front turn signal becomes inoperable at times. The foreword collision indicator warning will come on unprovoked at times. Both conditions correct when you cycle the ignition switch. I consider the turn signal problem a safety issue because it happens with no warning and oncoming traffic may not know I am turning left or changing lanes. When the foreword indicator appears, I doubt the system is operable.

On June 27th 2026 at approximately 3am, I was driving my Chevy Silverado Trail Boss with 6.2 engine, it suffered a sudden catastrophic failure and it completely seized while in motion. There were no warning or signs given while vehicle was in motion. This resulted in an immediate highly dangerous loss of propulsion on a dark 2 lane road. The vehicle would not crank and had to be towed to Estero Bay Chevrolet.

On Sunday, July 12, 2026, the 6.2L V8 (L87) engine in my 2023 Chevrolet Silverado 1500 ZR2 seized and locked up completely, resulting in total loss of propulsion. I was driving at 65 MPH when it felt like the transmission was slipping and I lost power and coasted the truck to the side of the road. COMPONENT: Engine (6.2L V8, RPO L87) — connecting rod/crankshaft failure consistent with Safety Recall N252494001 (NHTSA Recall 25V-274). The vehicle is available for inspection. It is currently at Cable Dahmer Chevrolet, where it was towed on July 13, 2026, and remains inoperable. SAFETY RISK: The engine seized during operation, causing sudden and complete loss of propulsion in traffic. This is the exact failure mode identified in Recall 25V-274 as increasing the risk of a crash. CRITICAL DETAIL: This vehicle previously underwent inspection under Safety Recall N252494001 and PASSED on Feb 3rd 2026 at VAN Chevrolet in Kansas City. GM deemed the engine non-defective and issued extended warranty coverage of 10 years/150,000 miles under the associated special coverage program. Despite passing GM's recall inspection, the engine suffered catastrophic failure. This appears directly relevant to NHTSA's open recall query regarding the effectiveness of GM's recall remedy. DEALER CONFIRMATION: A technician at Cable Dahmer Chevrolet has verbally confirmed the engine is locked up/seized. Formal diagnosis is pending master technician sign-off and submission to GM, expected the week of July 20, 2026. The manufacturer has not yet inspected the vehicle. WARNING SIGNS: No warning lamps, messages, or symptoms appeared prior to the failure. The engine failed without warning

I am filing a formal complaint regarding General Motors' handling of a critical vehicle component that has left my vehicle and many others in an unsafe condition. For more than over a one month, I have been waiting for a replacement gear shift module that is currently on backorder. During this time, I have learned that numerous General Motors customers are experiencing the same issue and are also waiting for this part to become available. My primary concern is that this appears to be more than an isolated parts shortage. If so many vehicles require replacement of the same safety-related component, General Motors should be evaluating whether this issue warrants a safety recall or, at a minimum, notifying affected customers of the potential risks. The gear shift module is a critical component that affects the safe operation of a vehicle. Allowing customers to continue driving vehicles that may have a defective gear shift module without providing a safety notification or timely repair raises serious concerns regarding public safety. I respectfully request that the NHTSA investigate this matter and encourage General Motors to: Explain the reason for the extended backorder of this critical component. Provide customers with a reasonable timeline for obtaining replacement parts. Determine whether this issue should be addressed through a formal safety recall or customer safety notification. Offer appropriate assistance to customers whose vehicles have been affected by this prolonged delay. Customers should not be expected to operate vehicles that may present a potential safety risk while waiting indefinitely for a critical replacement part.

Engine stopped while driving. Truck made dinging noise. Dash had no warning lights. Dash said need to press start button to turn on. Truck went into neutral by itself. Was able to pull over and put it in park. Tried to push the start button and nothing. Dealership said it needs a new motor. The truck has less than 10k miles. The motor has already been replaced once before at 4070 miles.

Upon purchasing a used 2023 Silverado, on the first night of ownership, I found the headlight on the passenger side to be defective. The high beams activated approximately a full second slower than the driver's side. It took me a few days to confirm what I was seeing, where I immediately reached out to help from the Chevy dealership it was purchased from. After back and forth, the dealership refused to fix this saftey item as it was "still operational just not 100%" or something to that affect (not a direct quote). The extended warranty company doesn't typically cover headlight housing. The dealership locally says both headlights need replacement. Chevy Corp is involved, under claim 104164057. I've brought to their attention that I have found several reports of this defect online for similar vehicles and model year. My contention is that, particularly due to being the passenger side, this malfunction could lead to accidents and collisions due to distraction of troubleshooting, and the delay of lighting on the side where animals and night hazards typically come from. I've read online reports of these headlights may take up to 3 seconds between sides to both activate, with one side running slower than the other, and eventual failure where the switching mechanism will get stuck. A Chevy dealer confirmed the defect and recommended replacement of both headlights, at my cost, for approximately $4000. Chevy is still investigating and trying to find a conclusion with the dealership, but I contest that I have malfunctioning saftey equipment that could lead to harm or injury, and at the moment, both dealer and manufacturer have been unwilling to resolve the issue. The failure occurs both in auto-headlight and manual modes.

The infotainment system is experiencing a freezing screen, audio spikes, and constant restarts.

While shifting my vehicle from Park, a "Service Transmission" warning message appeared on the dashboard. The warning would illuminate and then disappear, but the vehicle continued to shift into the other gears. At the time the issue occurred, my truck had only 47,000 miles. I brought it to Blasius Chevrolet in [XXX] on XXX, for diagnosis. The dealership determined that the Transmission Control Assembly (Part # XXX) had failed and needed to be replaced. I was informed that this repair was not covered under the powertrain warranty because Chevrolet considers the Transmission Control Assembly to be excluded from powertrain coverage, and my basic warranty had already expired. I was quoted more than $900 for parts and labor. Initially, I was told the replacement part would arrive within a few days. Later, the technician stated that other Chevrolet dealerships had the part in stock. However, after contacting those dealerships, he was told they would not release their inventory. Chevrolet then advised that the part was on national backorder, with the earliest estimated availability of XXX. As a result, I have been without my truck for approximately one month, creating a significant hardship. After researching this issue, I found numerous reports from other Chevrolet owners experiencing the same failure involving the Transmission Control Assembly. The apparent frequency of these failures, combined with the nationwide backorder of the part, suggests this may be a widespread defect rather than normal wear and tear. I believe Chevrolet should either: Cover this repair under the powertrain warranty, as it directly affects the operation of the transmission, or Issue a recall or warranty extension if this is determined to be a common defect affecting vehicle safety and reliability. I am submitting this complaint because I am concerned that a failure of the Transmission Control Assembly could impact the safe operation of the vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A valve on the 3.0L Duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for GM and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that GM knows is their fault.

MOMENTARY WHEEL LOCK UP. ENGINE WARNING LIGHT CAME ON. Safety warning not to drive as could cause catastrophic damage to transmission. Same symptoms as noted on update GM bulletin N242454441. 12/24. Only extends warranty 2020- 2022 models up to 150,000 miles. Gen 3 Transmission Control Valve appears to be the fix... My vin not included in the extended mileage. I just turned 62,000. Just out of Standard Warranty.

When merging onto the interstate, the vehicle lost ability to shift, started lurching and would not accelerate. No prior transmission issues had occurred and the sudden loss of shifting capability was a significant safety risk. This was GM Case# 89525980 The Transmission Valve body assembly was faulty and gave out with no warning. It had to be towed into the GM dealer and repaired for $2519.79

I have a complaint about GM and my 2023 Chevrolet Silverado 1500 LTZ regarding the radio / infotainment system failure after attempting a recommended software update, and the resulting degradation of installed safety features. On 08 MAY 2026, my infotainment system indicated a software update was necessary, so I followed the directions to complete the update. When the update was complete, my infotainment screen said there was a failure and to take it to the dealership for repair. The entire infotainement system is inoperative. The soonest appointment I could make was for 18 MAY 2026. On 18 MAY 2026, I took my Silverado into the dealership where I have it serviced to address the failure of my infotainment system. My service advisor informed me that I would need a new radio and that these radios are on a national backorder list. My advisor informed me that they have other customers who are experiencing the same issue and have been waiting for the replacement radio since January 2026. My advisor informs me that there is no estimated time of resolution. This defect inhibits safety features such as; use of OnStar, Google and Apple Maps that provide travel advisory hazards, parking camera views, vehicle systems status. Thank you.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 50 MPH with his wife and grandchildren inside the vehicle, the check engine warning light, collision warning light, and several other unknown warning lights were illuminated. The contact stated that the message "Braking System Failure - Do not exceed 62 MPH" and the trailer brake message was displayed. The contact continued to drive the vehicle; however, whenever the brake pedal was depressed, the vehicle failed to slow as intended. The vehicle was taken to a dealer where it was diagnosed and determined that a software update was needed. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 54,000.

My truck has the L87 motor on recall. i purchased it brand new and paid top dollar for it. I've had issues since I've bought it. All of my maintenance has always been done at the dealership from regular maintenance to purchasing brand new tires. I am very disappointed to have a truck that concerns to drive, i do not take my family out in my truck because i am not confident in its reliability and safety. multiple times i've taken my truck in for service and let them know to complete an oil change, tire rotation and to check an issue with a "tick, clunk and knock" just to be told it was "normal for the 6.2". my normal dealership has blocked off appointments online and you'd have to call to try to set one up. I demanded a diagnostic one time when the truck was acting weird and the tech stated "stop by, i'll squeeze you in" in which i did. however, i wasn't given any documentation since "i didn't have an appointment". After reviewing all of my service records, i come to notice not once time did they mention they did a diagnostic check. Only the recall test shows on one of the service records. I've had 3 different viscosity oils in my motor from the dealer stating GM recommended it. I had to night drop my truck on June 14 as it was making a weird noise from the engine and it felt like it had less power. I waited 2 days and the dealer did not contact to even state they have my truck in service. when i called to ask the status i had to agree to text message communication in which they replied, "at best it will take 2 weeks just to look at it". I asked for a loaner since i need a truck for work and transportation, they replied they do not have any and I will be placed on a list. My truck is still under original powertrain warranty and they cannot even provide a loaner. i feel that they are brushing me off to buy time and here i am making hefty car and insurance payments for a truck i do not have nor a truck that I NEED to provide for my family. GM does not care!

Fuel regulation module K111 part number GM13540028 failed and when this part fails the truck is stuck where it is. The brakes are locked, the truck cannot be started or put in neutral. If the truck stops on the road or freeway you are completely stuck where you are in the middle of traffic. This part fails often and failure leads to a very dangerous situation.

“Service transmission now unable to shift soon” message. Vehicle is stuck in park. Message appeared in May. Transmission stuck shortly after. Safety is at risk due to transmission being unable to shift due to faulty module that is widely reported and known to Chevrolet.

6/12/26 ( 2023 Chevy Silverado - 6.2 liter engine) While driving at approximately 40 MPH on a two lane road, the truck shut off. After multiple attempts, the engine failed to restart. The transmission locked up in park and would not release. This required the truck to be dragged up on the flat bed wrecker instead of rolling freely. Prior to this instance there have been several issues with the electrical system. 1. radio sound shuts off. does not come back on. 2. Head lights stay on for 10 minutes after vehicle is turn off. 3. Tail gate opens on it own. Tail gate doesn't open with fob. 4. door locks fail to operate correctly. 5. When drivers door is opened a beeping sound starts and doesn't stop until door is closed. I have reported these problems to GM & have two case numbers. The dealership reports that the 6.2 replacement engines have had multiple failures.

My 2023 Chevrolet Silverado 1500 experiences an intermittant, uncommanded mechanical drivetrain lockup and severe binding when accelerating from a complete stop. The vehicle rolls fine in a straight line for several feet, but the exact moment the steering wheel is turned slightly (a couple degrees), the drivetrain violently binds up. This creates resistance in the steering and acceleration, as well as a severe physical and audible metallic clunking slam and massive shockwave vibrations felt directly through the steering wheel, floorboards, brake/gas pedals, and driver’s seat. During the last event, the vehicle threw a "Service 4 Wheel Drive" dash message and refused to shift out of "Auto" mode back into 2WD. Because this is a pure mechanical interference/binding issue, it does not consistently throw active electronic trouble codes. A standard OBD2 code scan will show nothing. After turning the vehicle off for several hours and testing again, the problem persisted. After towing the vehicle to a dealership (6/10/2026) it sat for at least 5 days before dealership service looked at it. By this time, the active warning lights cleared. My initial servicing dealership refused to perform physical hardware or fluid diagnostics under my factory warranty, stating they would not look at the vehicle unless I paid $860 out-of-pocket or until the drivetrain "completely grenaded" on the road. Because this uncommanded lockup restricts my ability to steer the vehicle safely from a stop, it presents an immediate crash hazard. At the direction of General Motors Corporate, I am escalating this issue and moving the vehicle to a secondary certified facility (Feldman Chevrolet of Novi) on June 23, 2026, for a formal physical hardware and fluid tear-down inspection.

Vehicle would not start while on vacation. Called a tow to take to GM dealer. Turns out the fuel pump control module was bad. Some 2023 with a 5.3 had recalls. I was told my bin didn’t qualify so GM told me to contact you.

ON MONDAY, 6/15/26, WITH APPROX 45,400 MILES, I WAS DRIVING DOWN THE ROAD AND TRUCK SAID SERVICE TRANSMISSION. THE GEARS WOULD SHIFT, BUT IT LAGGED A LITTLE BIT. I SCHEDULED AN APPT FOR TWO DAYS LATER, AND ONLY DROVE IT WHEN I ABSOLUTELY HAD TO, WHICH WAS ONLY TWICE BEFORE MY SCHEDULED APPT. I GET IN IT TO DRIVE AND IT SAYS SERVICE TRANSMISSION- UNABLE TO SHIFT SOON, THEN ON MY WAY TO THE DEALERSHIP, IT SAYS ALL OF THAT, PLUS SERVICE DRIVER ASSIST SYSTEM. CHAVY'S QUALITY ASSURANCE TEAM NEEDS TO GET IT TOGETHER! THIS IS ABSOLUTELY RIDICULOUS.

Engine failed and no light or warning besides check oil was shown on truck. The electrical system also went out (a year before engine failure) so car wouldn’t start.

While traveling on the interstate towing a fifth-wheel camper going 55 mph, a message appeared on the dash instructing me to press the Start button. I pressed the Start button, but the vehicle would not start. When I pressed the Start button the entire instrument cluster and navigation display went out. We were able to safely coast to the breakdown lane, skidding to a stop. We remained in the breakdown lane on a busy highway on a holiday weekend in 90+ degree heat for 7+ hours before being towed to a nearby dealership. When the right type of tow truck arrived (capable of towing the truck and camper off the highway), the driver had to remove the driveshaft before the vehicle could be towed to the nearby dealership. This is because of the electronic shift. If the vehicle is not running it cannot be shifted out of park without a special tool. We felt very unsafe sitting in the breakdown lane with cars whizzing by shaking our camper and vehicle at each vehicle passing. Not 1 time did the police stop to provide assistance/make sure all were ok, etc. The vehicle has since been towed to the local dealership and after they inspected the vehicle it was determined the engine seized due to debris in the engine. A replacement engine is on backorder. The engine had already been inspected for the recall and GM 6.2L L87 "fix" was performed, but this did not stop the engine from seizing.

Check Engine has been triggered by faulty TCM. Vehicle is a 2023. Dealership says they have repaired a few others.

The entire engine was replaced at 5 miles due to catastrophic failure. Work was performed by Ciocca Chevrolet in Atlantic City New Jersey

At approximately 24,000 miles the engine had catastrophic failure under normal street/highway driving conditions. The engine is the 6.2L V8. The issue began with a high pitch squeal or chirping sound and noticeable power loss. I parked the truck over night and then drove it to the dealer first thing the next morning. While on the way to the dealership, which was less than 20 miles away, the engine began having much bigger issues. A loud knocking noise was apparent and the rear end began locking up causing the tires to also lock up. Once at the dealership the engine completely failed and locked up. The engine did have the newly recommended 0W-40 oil installed prior to the failure.

I was travelling on the highway at approximately 72 miles an hour in the left lane trying to pass a vehicle in the right lane. while accelerating my truck was like the brakes were slammed on and all kinds of lights starting flashing. This included the check engine light, low oil pressure light and lane assist lights. The truck shifted into Neutral and I could not place back into drive. I swerved and almost lost control of the vehicle and nearly missed colliding with the safety rails on the left of the road and then with the car on the right side. I then pulled onto the shoulder after nearly being rear ended by another vehicle approaching on the left. The vehicle would not react to the gas pedal. I pulled onto the shoulder and turned the vehicle off. Tried to restart but again nothing but mutliple lights and warnings. I checked my app for Chevrolet and it stated that the vehicle needed engine and transmission system service. Variable valve timing system needs serviced. Ingition system needed serviced. The onstar diagnostic alert indicated P0016 was detected. I opened the hood to inspect and the coolant overflow was spewing coolant. I checked the oil level at that point and it was just a little below full. I had taken this vehicle into the dealership two other times stating that the vehicle had stalled before on the highway but not to this degree. The other two times it stalled when accelerating it would allow me to pull over and restart. But both of those times I never had any flashing lights or diagnostic codes. I explained this to the dealership and how unsafe it was. Both of those times almost ended in a vehicle accident with other vehicles around me. The dealership said they could not diagnose any issues unless the truck created a diagnostic code. These issues have been ongoing with these vehicles for a long time and the dealership just did not want to deal with them. I had the vehicle go thru the recall diagnostic tests. It did not fix them

Transmission went out while driving on highway, entering limp mode. Ended up needing a valve body replacement at only 20k miles which was covered, but now I am having more transmission issues still with delayed forward engagement and slipping gears and it is only at 65k miles. Seems to be a lot of customers having the same issue. Took months for the truck to be fixed as "many other trucks" were waiting on the same part according to dealership.

See attached document for complaint.

While driving, the vehicle suddenly displayed “Service ESC” and “Service Traction Control” warnings. Shortly after, the engine stalled and the vehicle became difficult to restart. Vehicle experienced rough running/misfires and loss of power. Diagnostic trouble codes retrieved included P0300, P0106, P3498, P00FF, and U1962. The issue appears intermittent but creates a serious safety concern due to unexpected stalling while driving. Concerned about possible electrical, engine management, or stability control system failure affecting safe operation of the vehicle. No prior warning before incident.

This engine only has ~20,000 miles on it. The engine failed in relatively heavy traffic and could have easily resulted in a serious accident due to inability to route my vehicle to a safe area while under power. This all happened without any prior warning, no check engine lights, noises or lamps or symptoms. The dash simply illuminated with a "Press Start" message.The truck was towed to the dealer for evaluation. The dealer called me today (5/26/2026) stating the engine was seized and a new engine would have to be ordered from GM for installation. This event occurred while the vehicle (2023 Silverado ZR2) is still under the original 36 month/36,000 mile warranty.

Had a vehicle update for my 2023 Chevrolet Silverado and now my Onstar Module is toast and no longer under warranty bc I have 37,000 miles. Many reports of this happening to 2023 models but no recalls for this. Why should I have to pay $1000.00 for a part that is failing in many vehicles of the same year.

The contact owns a 2023 Chevrolet Silverado. The contact stated while driving at approximately 40 MPH, the vehicle stalled, the brakes were inoperative, the gear shift was stuck in drive, and all of the doors and windows were locked and inoperative. The check engine warning light was illuminated and the "please restart the engine" message was displayed on the instrument panel. The vehicle was taken to a dealer where it was diagnosed that the fuel pump regulator module needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 373200.

Onstar Module not working. Stop working in October of 2025 after a software update.

On 4/09/26, while visiting friends near the border in [XXX] from [XXX] and driving on a dry paved road we lost the ability to stop the truck and engage the brake system. To avoid a crash, I drove the truck up onto the sidewalk and closed my eyes. Fortunately we did not crash into stopped cars but the truck does not work and it has body damage to all sides. Now when the key is in forward collision system unavailable, service traction control and service ESC shows on dash. Truck is unsafe and a hazard on the road. A call to GM has been made waiting on a response. Gm case#XXX. Truck is 2023 with 62k miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In 2024 there was a recall for the tailgate locking mechanism - We did not receive that recall - but the part went bad causing the battery to drain - and it had to be repaired. We had to pay for the service $500.00 - We I asked the dealership about this recall they said it did not include my vehicle. But it was indeed that part that went bad. I lease the truck - I had every intention of purchasing after the lease - I am over the miles and was told it was out of warranty. I certainly would not complain about paying for it - but there was a recall last year for said part. Could some please reach out to me regarding this - Thank you

Vehicle has experienced repeated electrical and safety system failures since purchase in 2023. Affected systems include forward collision warning, blind spot monitoring, parking sensors, cameras, and infotainment. Failures include complete loss of camera functionality (rear and front), infotainment system shutdowns or resets while driving, loss of audio, and volume malfunctioning (including sudden increases or no response). The vehicle has also generated false safety alerts, including forward collision warnings and blind spot alerts when no hazard was present. These issues have occurred while the vehicle was in operation, creating safety risks due to loss of visibility systems and unreliable warning alerts. In multiple instances, the system would become completely non-functional for extended periods, sometimes lasting days or weeks, before temporarily returning. The problem has been reported to a dealership multiple times and has been inspected and serviced. Repairs have included software updates and component-related work; however, the issues have continued to persist or reoccur. The failures are intermittent but recurring and have not been permanently resolved despite multiple repair attempts. The condition reduces driver confidence and creates unsafe operating conditions due to unreliable safety systems and loss of critical features while driving.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving 65–70 MPH, there was an abnormally loud sound coming from the vehicle. Several unknown warning lights were illuminated. The contact attempted to pull over to the shoulder of the road, but the vehicle lost automotive power. Additionally, the engine had seized. The contact stated that while attempting to start the vehicle, the vehicle failed to restart. The vehicle was towed to the dealer; however, the vehicle was not inspected. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. In addition, the contact stated that the gear shifter failed to shift to neutral. The failure had occurred while driving on a busy highway and created an unsafe driving condition. In addition, the contact stated that New York State Troopers assisted with the traffic control. The manufacturer was made aware of the failure. The failure mileage was approximately 47,000.

At 29k miles, truck was receiving an oil change and general maintenance. Metal flakes were found in the oil and small shaving in the bottom of the drain bucket. Vehicle was sent to a GM dealership to be tested. Engine passed pico test even though metal was present in the oil.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at 70 MPH, the vehicle hesitated while depressing the accelerator pedal. The vehicle continued to lose power with a huge cloud of white smoke coming from under the hood. There was no warning light illuminated. The contact pulled off to the shoulder of the roadway, and the vehicle shut off unexpectedly. Due to the failure, the vehicle was towed to the dealer and was diagnosed with engine failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.

Transmission has jerked/bumped in past and now at approx 85K miles, it supposedly needs a new transmission. I've heard it is a pretty big issue and seems llike relatively low mileage for this to be happening to 2023 year model. I certainly don't drive it hard and rarely tow or haul heavy loads.

One day the trucks transmission started to struggle to find the next gear after taking off from a light. The next morning it did it again and that night did it a third time. The third time it about brought the truck to a stop at 30 mph and made a bang noise, in which a check engine light came on and a message saying speed limited and drive with caution. The truck only has 20,000 miles and already is having transmission issues, which is just unacceptable.

Onstar isnt working the clock wont stay on time the telematics control module went out on a brand new truck just past the 36,000 mile warranty

I am reporting another engine failure on the 6.2L L87. This engine passed the initial recall testing and the oil was changed to 0W40 on September 30, 2025. However, my engine in my 2023 LT Trail Boss started knocking on Friday, March 20, 2026 (at 22,500 miles) after I picked up my children from school. Thankfully it started as I pulled into my driveway with them so they weren’t in any danger. No loss of power on the truck or warning lights visible. However, it was loud enough and odd enough for my [XXX] olds to even notice the sound in the cab. It was dropped off at the dealership on that Saturday morning and the GM dealership was finally able to look at it on Wednesday, March 25th and confirmed what was expected. The advisor stated the engine will need to be replaced due to the engine heading towards bearing/crankshaft failure. I am still currently without my truck as of today (April 4th) with no repair date in sight. I will say that the dealership service advisor has been very good about communicating about its status. However, he stated that he has had no luck finding an new engine and is unable to give a timetable in getting one. He did offer to start a PO for a rental car through enterprise. He stated they are not giving loaners, but could get a rental car. He also stated that it would not be a truck due to GM only giving $50 per day towards a rental. So here I sit currently without my truck. I see multiple reports about the engines being on back order and even the replacement engines are failing within the fist 500 miles. Some reports indicating they are on the third or fourth engine. Something needs to done about getting these trucks bought back by GM. They have clearly failed with this engine and are replacing the failed engines with the same thing! It is a well documented manufacturing flaw and design! I am thankful it occurred near my home. I would not have been happy with a catastrophic failure on a highway with my [XXX] old children in the truck!!

Vehicle shut off while driving. Dash codes said low fuel and low voltage. Tank was full and driven twice that same day for a combined 20 miles. No wrongs of failure

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 65 MPH, the vehicle started to lose motive power. There were several unknown warning lights illuminated, and the message that the vehicle would not exceed 55 MPH while driving. The contact stated that after driving for several miles, the message appeared that the vehicle would not accelerate to 30 MPH while driving. The contact had taken the vehicle to a local dealer, who diagnosed the vehicle and determined that the DEF tank heater needed to be replaced; GM Part Number: 85856213; however, the part was on a national back order. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 67,000.

At cold start vehicle often required several seconds for the transmission to engage before moving. After traveling at highway speed (45+ MPH) vehicle began to make clunking noise as if the transmission were changing gears but it was not and the RPMs on the tachometer did not change. Instances became worse and more frequent over 6 month period, vehicle never displayed any codes and no notifications or check engine/transmission lights on driver information center. Took vehicle to O’Fallon Buick GMC and was advised torque converter and transmission valve body had failed and needed replaced. I inquired about ongoing issue with this vehicle based on my findings online and was told it was not a recall issue at this time. Truck has 74,000 miles and service records for all maintenance to date.

Tailgate opens on its own after parking truck. No buttons inside or on the key fob are pressed and the tailgate randomly opens. Caused the battery to drain as well.

I'm reporting a 5mpg fuel economy reduction immediately following the 6.2L L87 engine recall (NHTSA #24V795000). I use 93 octane and monitor my fuel mileage consistently. I bragged about my fuel economy in my 6.2l until after the recall was applied. This is going to cause a financial hardship as I'm on fixed income after Servicing 29 years in the Army and 100% disabled. There is no other reason my mpg should have changed as my driving habits have not.

Battery keeps going dead 4 batteries in 4 months think it is caused by power tailgate release

While driving on the freeway without warning, my engine stopped working. My vehicle was towed to the Chevy dealership where they confirmed that I was the latest victim of the ongoing engine failure problem with the 6.2 L engine. There was no warning, no sign that I had a problem. My engine just simply stopped working on a busy freeway. I was barely able to make it to the shoulder where I had merging traffic coming on the freeway behind me. I’m deeply concerned that Chevy will replace it with the same faulty engine and I will be put in the same danger situation again in the future.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that on two separate occasions while hauling the camper, the "High Diesel Exhaust Fluid", Exhaust Fluid Range", and "Fill DEF (Diesel Exhaust Fluid) Now" warning messages were displayed on the instrument panel. The messages indicated that the Diesel Exhaust Fluid was low and needed to be replenished. The contact stated that the failure caused the instrument panel to freeze and not operate as needed. Upon attempting to refuel the vehicle, fuel failed to enter the fuel tank since the diesel tank was full. The vehicle was taken to a dealer, where the contact was informed that the failure was an electrical glitch and that there were no issues with the Diesel Exhaust Fluid system. The contact was also informed by the dealer of Technical Service Bulletin: 22-NA-150, which the contact related to the failure. The dealer reset the vehicle, which caused the instrument panel to return to normal operation. The manufacturer was then notified of the failure, and the contact was informed that vehicle was not included in the TSB. The contact was given a case number and was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 55,000.

My engine completely died, and a complete loss of propulsion happened. My safety was put at risk due to no power while on busy highway. This problem with L87 engines (6.2) has been reported extensively. The vehicle was inspected for GM Program # N252494000, NHTSA 25V74 for above issues and was inspected on 2025-08-28. Inspection passed, but the failure ultimatel happened on 2025-02-25. Dealer indicated engine was covered under original powertrain warranty and GM would send a remanufactured engine. Dealer has still not received the engine as of Monday (2/23), which is almost a month later. While driving on a US highway in a rural area, my engine suddenly died while driving approximately 60mph. The restart engine light came on, and I quickly was unsure what was happening as I felt myself slowing down slightly after realizing I had no power and the engine would not restart. I believe it went to neutral automatically. I was in the inside lane, and it was incredibly dangerous due to traffic around me. I could not easily exit to side of road due to the traffic, but luckily a gap formed, and I was able to abruptly get off the road. I have kids in the car daily, and this would have been life threatening had it happen in any other scenario, or especially in a larger city or busier highway. I am confident this is related to GM's issues with the 6.2 liter engines. I have a 2023 Silverado 1500 ZR2 that this happened to. The loss of propulsion is clearly due to the defect in these engines.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the engine failed after the vehicle was repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact stated that while driving 70 MPH, the vehicle lost motive power. The message "Hot Oil Shutting Down" was displayed. The contact coasted to the side of the road, and the vehicle was towed to the dealer. The dealer determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 36,500.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle made an abnormal sound and failed to respond as intended. The vehicle was taken to the dealer. The dealer contacted the manufacturer and was helped in diagnosing the vehicle. The dealer replaced the front brakes on several occasions and replaced the rear brakes once. The contact stated that the 360-degree camera had become inoperable. The vehicle was taken to the dealer, where it was repaired. Additionally, the contact stated that while the dealer was completing a transmission recall repair, the dealer informed the contact that there was an engine oil leak between the engine and the transmission. The contact stated that while driving at various speeds, the engine overheated. The message "Reduce Acceleration - Drive with Caution" was displayed. The vehicle was taken to the dealer, where it was diagnosed with cooling system failure. The vehicle was repaired; however, the failure recurred. Additionally, the instrument panel was intermittently blank. The vehicle was taken back to the dealer. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was approximately 1,000.

Valve body went out while driving, drastically reduced speed, threw code p0747.

The vehicle lost power and went into limp mode on 3/3. I had it transported to a dealership and they said there was metal containments in the motor. I got it back on 3/17 and they said all was well but it never drove right. It broke down again on 3/20 and the said the throttle body was out. Why had they not found this issue before? This seems to be a recurring issue with this model truck.

Engine failed, started making noise and was shutting off, engine was locking up.

The Def guage does not work properly. After topping off with DEF the guage would not register being full. Also the guage would read over half full and within minutes I would receive a notification that the truck was going into limp mode due to be out of DEF. Happened several time while on a trip. Also truck went into limp mode while DEF was full.

Valve body in the transmission failed while driving on the freeway, all of a sudden it was like the car was in neutral and the RPM's went to redline. Dealer is telling me it is a known issue and has no idea on when they will be able to get parts because they have been on backorder forever. Says that they also have to replaced the Transmission Control Module (TCM). same thing no eta on parts. If this is a known issue why have they not recalled them. Fom what I see on line this failure is happening a lot to people, hence the unavailability of replacements parts.

Driving at highway speeds the message center prompted us to restart the truck and put itself into neutral. Upon attempting to do so, the message center read conditions not correct to shift. We were traveling in a single lane highway thankfully on a decent where we coasted into a parking lot. The truck list all power steering and brakes. We turned the truck off and attempted to restart. Lights were randomly flickering on and off, but the starter couldn’t turn the engine over. After 3 hours of waiting on Chevrolet roadside assistance we obtained our own tow service. The truck tires had seized up causing the driver to drag the truck into the flatbed. The emergency brake kept resetting itself. The following day 7/13 Chevrolet had the truck towed to the dealership. On Monday 7/16 we were informed the engine had catastrophic failure with less than 24k miles. This is the second major engine breakdown as the first was at 5k miles where one side of the engine had collapsed lifters. Engines are on back order but in reviewing other experiences the replacements experience the same issues. The truck is not a safe vehicle to drive.

The contact owned a 2023 Chevrolet Silverado 1500. The contact stated that while he was driving at an undisclosed speed, the engine sounded rough and ran rough. While driving at 75 MPH, the vehicle started shaking and started losing power. The contact pulled over and there was one more loud bang before the engine was blown. Additionally, there was an abnormal failure with the transmission. The contact referenced NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall repair. The vehicle was towed to a local dealer, where it was diagnosed with a blown engine, and transmission-related fault codes were retrieved. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 40,924.

The vehicle is currently exhibiting a loud, rhythmic metallic ticking/tapping noise from the top of the engine. This is a known precursor to a sudden, catastrophic loss of motive power as documented in GM Service Bulletins PIP5847A and PIP6101. The cause is attributed to manufacturing debris within the hydraulic valve lash adjusters, which prevents proper lubrication and causes valvetrain desynchronization. This defect leads to severe engine misfires (DTC P0300), "Reduced Engine Power" mode, and potential engine seizure. ​1. Component/System: The 2.7L L3B Engine Valvetrain / Hydraulic Lash Adjusters. The vehicle is available for inspection. ​2. Safety Risk: The audible ticking indicates imminent mechanical failure. This defect causes sudden and unexpected loss of motive power at highway speeds. Driving in this condition puts me at extreme risk of being stranded in active traffic or losing power while merging/passing, creating an immediate risk of high-speed rear-end collisions. GM is aware of this debris-related defect via TSBs but has not issued a safety recall to prevent the resulting power loss. ​3. Dealer Confirmation: Yes, confirmed by Chevrolet dealer on 3/18/26. The dealer knows about this particular issue, and decided not to act. ​4. Inspection History: Inspected by authorized Chevrolet service technician. ​5. Warning Symptoms: Loud metallic ticking/clacking that increases with engine RPM. This is a known precursor to a sudden, catastrophic loss of motive power as documented in GM Service Bulletins PIP5847A and PIP6101.

Tailgate unexpectedly opened when driving. Switch on and off when parked and drained battery

2023 1500 RST 6.2. Recall was done and performed last year. Truck passed so they changed the oil and sent me on my way. I have had zero issues up until last week. My gut tells me the replacement is going to be the same engine with the same failing parts that I already have so expect I may have issues in the future even after the new engine. -on interstate going 55MPH, went to accelerate to 70MPH and throttle did nothing; no rpm,no down shift, no speed change. Just dead. Suddenly the truck shut off the engine and kicked my transmission into neutral. I tried to restart the truck hoping it would fire just long enough to get me to a safe zone with no luck as the starter would turn but nothing from the engine. Mind you this was rush hour in a construction zone with no shoulder available at the moment. Luckily I coasted, got to the slow lane and was able to veer off safely onto the side of an exit ramp. No notice, no way to safely limp my truck, just a complete shut down. How this isn’t a lawsuit or more people haven’t been seriously injured or worse is beyond me- a total shutdown while driving highway speeds and no way to overcome or at least limit the speed for a short period is unbelievable. Even though warranty is now through 2033/150k miles for the powertrain due to the recall, and I’ve also thought about adding 3-4 years extended for bumper to bumper with all the tech, I now have ZERO faith in my truck or my safety once I get it back. I’m sure the trade value will also be considerably low due to the 6.2. I’ve owned Chevys for 12 years and am either going back to the 5.3 or switching brands altogether. Possibly a 5.7 hemi without etorque.

The adaptive cruse control will apply the brakes driving, it happens when driving and there is nothing in my lane as far as the eye can see. Sometimes the Silverado will go from 70 mph to 30-40 or less and back to 70. Most of the time it will apply the brakes for a sec and then off. One time it locked up the brakes from the low 60 ish MPH to almost stoped before I could get control. Every time this happens there is no cars, or abstractions in my lane. I have had the Silverado into 2 dealers for this problem about 25 times and they can not fix the problem and I have been told that they are done working on it and they can not find the problem and I will have to live with it. I don't fell safe driving it and have told that to them. I have asked many time to have a GM Engineer look at my Silverado and find the problem and they did nothing to resolve the problem. I need to a get this problem addressed before I cause an accident or am in one. I also have many other problems that they cannot resolve, The Blind spot mirrors light will go off all the time with nothing there or a car will pass on the left side and both the left and right mirror lights will go off. The Bluetooth will disconnect from the Silverado and the person I am talking to can hear me just fine and the call is no longer over the speakers in the Silverado it is on the ear piece of my phone and then will go back to the speakers on the Silverado. I will get an alarm that says "Take Wheel" with hands at 10 and 2 on steering wheel looking straight ahead. Get an alarm that have trailer light problem and will turn on blinker and it will flash quickly for 10 seconds and then is normal. Radio skips on FM, AM, XM, MP3 Player at times. The Silverado has spent over 4 months and 25 times at a dealer since I bought it new and they have nor been able to resolve any of the problems and I have been told by GM that they are done working on this truck and they can not find the problems. Thank You

RE: FORMAL COMPLAINT–RECALL FRAUD & VIN TAMPERING SUBJECT: Falsified Recall N252494000 & 18 U.S.C. § 511 Violations VEHICLE: 2023 Chevy Silverado (VIN: [XXX] ) INCIDENT: March 7, 2026 FROM: [XXX] | [XXX] I am reporting severe Federal Recall Fraud and VIN tampering by Kunes Auto Group (WI). GM records and physical evidence prove Kunes falsified Safety Recall N252494000 (L87 Loss of Propulsion) and sold an illegally rebuilt wreck with mismatched VINs. 1. Falsified Recall: On 4/9/2024, Kunes logged a PicoScope Inspection marking the recall "Passed" (Trans #XX-XXX). The NHTSA remedy requires installing a 0W-40 oil cap/flush. When the engine seized on 3/7/2026, it still had the factory 0W-20 cap. Kunes billed GM for a safety remedy never performed. 2. Concealed Defects: Despite the "Closed" recall, the truck exhibited L87 defect symptoms. I brought it to Kunes three times (Oct 2025 - Feb 2026). They dismissed the warnings and released the truck as safe. 3. VIN Fraud (18 U.S.C. § 511): The 2023 truck has 2025-stamped frame/axle parts. Holz Motors (authorized GM) blacklisted it on 3/6/2026 (RO #1583470), stating in writing: "DUE TO... MISMATCHED VINS DOOR TO DASH, SALVAGED REAR AXLE... HOLZ WILL NOT BRING THIS TRUCK IN." 4. Highway Failure: On 3/7/2026, the L87 motor suffered total Loss of Propulsion at 70 MPH in traffic. The sudden loss of power steering/braking nearly caused a multi-vehicle fatality. REQUESTED ACTION: 1. Audit Kunes’s PicoScope data for the 4/9/2024 transaction. 2. Investigate remedy fraud (missing 0W-40 cap). 3. Investigate tampered/mismatched VINs and off-the-books rebuild. 4. Sanction dealer for fraudulent safety certifications. I declare under penalty of perjury these statements are true.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. There was no warning light illuminated. The vehicle was towed to the dealer, where it was diagnosed and it was determined that the engine had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 41,100.

This truck has a 6.2 engine that was recalled, inspected, and made the switch to the new oil, but then failed. I believe you already have a recall query rq26001 related to this matter. I received the recall notice July 2025, took the vehicle to Covert Bee Cave in Austin, TX July 2025. They told me it passed inspection and put the new oil cap on. Within two weeks I began having transmission issues. I left the truck with them for three weeks and they could not do anything about the transmission. The transmission issue did not reappear until a couple of weeks ago. I took it to Capitol Chevrolet and they replaced a shifter rod in the transmission, but I am not convinced that was the issue as it still shifted rough. Just a couple of days later, before I could take it back to have Capitol look at the transmission, and while driving on an Interstate south of San Antonio, TX, the engine slowed down, flashed a warning "Oil Pressure Low Turn Vehicle Off" and it continued to slow. I was barely able to exit the Interstate, the truck stopped and would not restart. I had it towed to Vara Chevrolet in San Antonio ($440 tow expense) and it still would not start. The technician finally inspected it a few days later, said the engine is seized, and they will need to replace the entire engine, and that it is covered under warranty (there was plenty of oil in my engine). He did not say anything about the transmission. I believe this is an example of my vehicle passing the recall inspection, changing to the new oil, and the engine still failing - and at a very dangerous time on the interstate.

What component or system failed or malfunctioned, and is it available for inspection upon request? Glass sunroof blew outwards driving 60mph on the highway. No other vehicles were around and I did not see anything impact the vehicle. The glass was broken outwards and created an 8” by 8” hole in the sunroof glass. There was no extreme temperature differential, approx. 55 degrees outside. It has been repaired and not available for inspection. How was your safety or the safety of others put at risk? It sounded like a gunshot inside the truck, causing extreme distraction at highway speeds. Luckily the interior shade was closed and caught the glass, but if it was open all of the glass would have fallen on the passengers. Has the problem been reproduced or confirmed by a dealer or independent service center? No the dealership did not consider it a manufacturing defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Insurance inspected the vehicle and it was covered under a glass claim. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No indication prior to the incident at all. It happened out of nowhere.

Purchased 2023 Chevrolet Silverado ZR2 with 6.2 L engine in November 2025 with 3400 miles on it. According to the dealership the engine passed the recall on 09/25. At 6,500 miles the check engine light, ESC light, stability control light came on. Engine was running rough, degradation of engine power, and very rough transmission shifting. Vehicle was taken back to purchasing dealership and was told the lifters and rods will have to be replaced.

My onstar telematics system has failed. I lost all connectivity with onstar and have no vehicle crash detection, communication and onstar based safety feature available anymore. I took the truck to the dealership and they identified the telematics module as faulty and needs replaced. The onstar system buttons are off and will not turn back one and have been off since 2/18/26.

The Forward Collision Light Glitched out and I had to reset the fuse to get it back. The orange light stayed on until I fixed . The truck is only 3 years old and only has 017314 miles on it.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the tailgate lowered unexpectedly while driving at various speeds, and occasionally closed unintendedly. The failure also occurred while the vehicle was parked and turned off. The vehicle was taken to the dealer, and the failure was demonstrated. The tailgate switch was replaced. The contact became aware of a Canadian Recall, ID Number: N232426400, for the tailgate failure. The manufacturer was made aware of the failure; however, no repair was performed. The failure mileage was approximately 60,000.

The Guidance lines on my back up camera have gone out, and only shows a hourglass. In doing online research this shows up as being a large problem.

On [XXX], my 2023 Chevrolet Silverado 1500 LT caught fire while parked in my residential driveway at [XXX] . The vehicle had been started approximately 10 minutes earlier using the factory-installed remote start system. The vehicle was unattended at the time. My neighbor noticed the vehicle on fire and called 911. The Andover Fire Department responded and extinguished the fire. The fire department indicated the fire appeared to be electrical in nature. The fire appeared to originate in the dashboard and steering column area based on visible damage and fire progression. The vehicle had approximately 60,000 miles and was properly maintained. There were no prior warning lights, messages, or symptoms before the fire. The remote start system was factory-installed and not aftermarket. The vehicle is currently available for inspection by insurance, manufacturer, or investigators at [XXX] . The vehicle is likely a total loss due to the extent of the fire damage. This incident posed a serious safety risk as the vehicle caught fire spontaneously while parked near my home. The fire could have spread to my residence or caused injury if someone had been inside or near the vehicle. The fire department responded, and an official fire report is pending. Insurance claim has been opened and inspection is pending. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while stopped at a traffic light, the engine turned off and the instrument panel became inoperable. The vehicle was restarted; however, the failure persisted. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that on a separate occasion, the message "Tailgate Open" was displayed on the instrument panel. The contact pulled over to the side of the road and, upon inspection, noticed that the tailgate was closed. The vehicle was taken to the dealer; however, no cause for the failure was found. An employee at the dealer closed and opened the tailgate several times until the message disappeared. The contact stated that on a separate occasion, the radio stopped functioning, the driver's door unlocked unintendedly, and the driver’s side seat belt failed to retract as intended. The vehicle was taken back to the dealer, where it was diagnosed that the seat belts had failed. The contact seat belts were replaced. Most recently, there was an abnormal sound coming from the engine. In addition, the brake pedal was depressed, and the vehicle failed to respond. After a while, the vehicle was able to stop. The message "BRAKE System Failure” and “Replace Brake Pads and Rotors" was displayed. The vehicle was not diagnosed or repaired. The contact stated that the failure persisted. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 22,000.

Vehicle had recall for L87 engine performed, resulting in a change to 0W-40 motor oil and a new fill cap. Approximately one week later, the engine failed completely, with evidence of significant bearing wear in the used oil analysis I had performed. The engine has since been replaced under warranty. There was no prior warning to the failure, except for unusual noises during the failure.

Loss of engine propulsion while traveling down a highway towing a #5000 trailer at 65 mph. Less than five miles before the failure the vehicle experienced a momentary downshift of the transmission such as you would experience while climbing a hill or extreme headwind. No warning lights were present at that time or at any time prior to engine shutdown. Upon failure panel indicated "Press Engine Start" and transmission indicated "Park" though we were rolling/coasting at over 60 mph. Realizing that we had lost propulsion I guided the vehicle to the shoulder and stopped. Solid check engine light on at this time. Depressing the "Start" button while stopped would not start or crank over the engine. Boost box would not crank engine, slight noise from starter as if unable to turn engine over. Called tow truck, Seewald's Towing in St. Ignace, MI. Towed to nearest Chevrolet dealer Wheeler Motors Cheboygan, MI.

Engine light keeps returning after dealer visits for oil change. Exhaust heat shield rattles since day one of ownership. During Normal commute, when I accelerate reduced power comes on and doesn’t allow me to accelerate much. Engine Electrical System, including the Charging and Starting System. Checked battery, alternator, and starter

My 2023 Chevrolet Silverado 1500 has experienced two separate major drivetrain failures — complete transmission and turbo replacements — within two years of purchase, both during peak use months. The second repair kept the vehicle in service for nine months with no ETA provided until escalation. The repeated failures have rendered the vehicle frequently unusable, caused significant business loss, and represent more than normal wear. Documentation of repairs and dates is attached.

My 2023 Silverado 1500 6.2L ZR2 AEV with 17,500 miles went into the shop for the L87 Loss of Propulsion recall, on 20 OCT 2025. The dealership didnt contact me for 2 weeks, so I called. They than told me my truck failed the pico test and needed a new engine. I also asked for my leaf springs to be looked at under tsb for excessive noise. I also asked for my ZR2 to have the new update installed for the radio fix (my speakers crackle when I talk to people on bluetooth). They had my truck from 20 OCT 2026 until 27 JAN 2026 for a total of 99 days straight. No loaner was available. I had to call GM customer service every week for subpar updates from the dealership. Im active duty army so not having my pov to report to work was very stressful. When I got my truck back, it was covered in dirt, oil on the exterior paint and inside the engine bay. The dealership didnt update my truck as requested and didnt touch my leaf springs at all. They said it would take 5-7 weeks to get new ones, but I needed my vehicle back which is anitated on the work order. Thr parts were all delivered 45 days after it sat there and my truck wasn't worked on until day 94 as advised by the service advisor, as the mechanic would get to it after his next vehicle. I asked how is my truck not priority sitting there for 93 days at the time. GM customer service has submitted my vehicle payment reimbursement as I paid 4 payments while having no vehicle or loaner. $44 a day for a rental at my duty station would cost me considerable amount of my own money to cover the rest and would not be a similar vehicle to my truck, as ot would be a small car. JN Chevrolet in Honolulu did not communicate when it failed the test for 14 days, I had to call them, they gave zero updates for 2 months, I had to call GM customer service. I only received 4 calls in total from the dealership when I asked to speak to the manager. (Who never called me back). I got my truck back filthy, other services ignored. 3rd Silverado and last.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at undisclosed speeds, the vehicle lost power, jolted, and then stalled. The vehicle rolled while on a hill. The check engine warning light was illuminated. Additionally, while accelerating from a stop, the vehicle stalled again. The vehicle was taken to an independent mechanic and a transmission-related error code was reset; however, the warning light reappeared. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was contacted and assisted with the cost of the repair. The failure mileage was approximately 35,000.

The contact owns a 2023 Chevrolet Silverado 1500. The contact was driving at approximately 35 MPH, and the steering wheel was difficult to maneuver, causing the vehicle to veer off the road and crash into a tree and a steep ditch, where it came to a stop. The air bags did not deploy. The "Service Power Steering" message was displayed on the instrument panel. The contact sustained injuries, including arm lacerations. The contact did not seek medical attention. A police report was not filed. The vehicle was towed to an auto body repair shop to get a diagnosis; however, the vehicle was not diagnosed as of yet. A dealer was contacted and went to the auto body repair shop to diagnose the vehicle; however, the vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was not notified of the dealer. The failure mileage was approximately 16,000.

I am writing to formally document a series of catastrophic mechanical failures involving my vehicle, as well as serious inaccuracies currently reflected on the Carfax report. At approximately 15,000 miles, my vehicle experienced a catastrophic engine failure that required a full engine replacement. Less than 900 miles after the engine replacement, the vehicle then suffered a catastrophic transmission failure, which also required replacement. In connection with the transmission failure, there was also a fuel module issue that left me stranded. These failures were not minor or routine service events. One breakdown occurred on a major roadway and required the road to be shut down due to the vehicle being disabled. Another breakdown occurred on the Florida Turnpike as a result of complete engine failure, leaving me stranded in a highly dangerous situation. Despite the severity of these events, the Carfax report does not accurately reflect what occurred. The Carfax report does not state that the engine was replaced, and the transmission failure is not identified as a transmission replacement at all. Instead, it is reported as routine or normal service, without any indication that a catastrophic transmission failure or replacement occurred. This misrepresentation significantly understates the true condition and mechanical history of the vehicle. Due to the repeated catastrophic failures, the circumstances under which they occurred, and the risk posed to my safety and the safety of my family, I am genuinely afraid to drive this vehicle. I want to ensure that all of this information is properly documented and that the vehicle’s records accurately reflect its true history and condition.

CONCERN OVER 6.2 ENGINE FAILING WHILE IN CONGESTED TRAFIC

My husband was driving on Plank rd/rt 219 towards Ebensburg PA when the truck started to buck and he turned off the main road and it shut down. It would not start just said low battery. I had it towed to the garage we use. They just confirmed it is the engine it locked up. I had the inspection for the recall and had the oil changed prior to this happening.

I was notified that my 2023 Silverado had an open recall (L87 Engine loss of propulsion). I brought the truck to the dealer for the recall on 8/19 with 35,921 miles on the vehicle. The inspection was performed and I was told it passed. When I asked about the extended special coverage they told me they didn't know what I was talking about. Only 4 months and 4,567 miles later, on 12/29, the vehicle shutdown in traffic and was not able to restart. The engine had failed and the starter fuse blew due to the motor being seized. The dealer relaced the engine due to the same recall that the engine had already been inspected and passed the inspection for.

My truck took my truck to Austin and back. Woke up the next day. Started it at approximately 4 o'clock in the afternoon and had engine oil low alert. Got out check the oil in my truck and there was none on the dipstick with the truck off of course. Checked at two other times allowing the dipstick to stay in for three or four minutes. Still no oil on the dipstick. Did not drive truck any further. Truck has the 6.2 L and I had the recall applied to the truck on December 8. The truck has 88% of the oil life remaining according to the truck.

I am sending this email to report that my 2023 Chevrolet Silverado had its rear brakes lock up momentarily on consecutive days (1/13/26 & 1/14/26) driving 70-72 mph.  Each occurrence came on without warning and only lasted a brief moment, but locked up hard enough for my rear wheels to screech and slam me forward in the truck, thankfully there were no other vehicles near me. I took the truck to the dealership first thing in the morning on 1/15/26 to be informed later that day that the truck didn't show any codes.  The service department at my dealership contacted the TAC Dept. at GM and they determined that the problem was caused by the brake light wiring from my truck topper (that was after they asked if the customer had added any accessories to the truck).  I have had the topper for 3 years without any issues.  I reached out to the company that installed the topper and the owner said that GM is giving me the run around and trying to point the blame elsewhere. He himself has installed 100's of toppers and they follow the wiring instructions from Leer Toppers. He did a 30 second Google search and said [XXX] , the problem you have experienced is well documented online, GM knows what the problem is with your truck". My truck was at the dealership for 5 days before they released it to me, even after I told them that there are known and documented cases of their trucks experiencing momentary rear wheel lockups. I have called GM Customer Service twice and left messages regarding my truck and TAC # and haven't received a return call. I am fearful that when this happens again and if it does so in the wrong place at the wrong time the end of this story may be tragic.   If I was pulling a trailer, driving on ice or in rush hour traffic I can't imagine the outcome. GM knows they have a serious problem and they is comfortable in releasing a dangerous truck back onto the roads. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 1/24/26 I used the remote starter to warm up the truck and it started but within 3 minutes it shut off. The temperature was in the single digits. So I tried the remote again and it wouldn’t start. And the remote start hasn’t worked since and the check engine light is on. Two years ago when the brake module failed right before that recall the temperature was very cold that day too. Just two months ago the check engine light came on and that time the dealership said the battery failed . It also printed out a whole page of errors , at the dealership.

My truck passed the recall PICO test right at 20,000 miles. The dealer put thicker 0w40 oil in. Less than 2,000 miles later, upon hard acceleration from 5-8mph, the engine climbed to 58mph then lost power, shifted itself into Neutral and coasted to the side of road. Truck was towed and told the engine seized up. Changing the oil did not make sense to me as lubrication was always available previously, thickening it does not change the port mill sizes for properly oiling the crank bearings. Now the new engine is revised but I see failures in low milage 2026 models happening.

The contact owns a 2023 Chevrolet Silverado 1500. While driving approximately 45 MPH, the message “Reduce Acceleration – Drive with Care” was displayed. The vehicle was driven to the residence with an abnormal rattling sound coming from the vehicle. The vehicle was taken to a local dealer, but the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

A few times before engine locked up, i was driving and out of no where it would shut off/lose all engine power and woukd shift to N automaticlly. Those 2 times it happend on the highway had to pull over to be able to turn it on again. The 3rd time it was at a busy intersection all 3 times i was with my wife and kids so was very dangerous. 3rd time it never turned on again with a low oil pressure message. Got it towed to the dealership and they told me the engine was locked up. So now at the dealer getting a new engine and radiator ect.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer, and the failure was associated with a coolant sensor failure; however, it was unknown whether the dealer had repaired the vehicle. The dealer then informed the contact that the vehicle was safe to drive. However, while driving 65-70 MPH, the engine overheated and the vehicle stalled. Several unknown warning lights were illuminated. The contact was able to pull over to the side of the road, and the vehicle was towed to the dealer. The failure was initially related to a coolant sensor, and the dealer advised the contact that the part was ordered; however, upon following up, another technician advised the contact that a digital multivalve was ordered. The contact stated that upon returning to the dealer, the dealer advised the contact to sign the service documents. The contact stated that after insisting on reading the service documents prior to the signature, the dealer provided the documents to the contact; however, the dealer later snatched the documents from the contact while the contact was reading the documents. The contact stated that it was unknown whether the vehicle was serviced. The service manager later informed the contact that the vehicle could not be repaired because the contact and the dealer could not come to an agreement. The contact informed the dealer that the vehicle should be repaired under the warranty. The vehicle was picked up from the dealer unrepaired. The check engine warning light was illuminated. The manufacturer was notified of the dealer's denial by the dealer to repair the vehicle. The manufacturer informed the contact that there would be a follow-up with the dealer. The failure mileage was approximately 34,000.

After have the engine tested it was determined that my vehicle will receive the 0W/40 oil. After that change I have notices a lot of rattling and the engine not behaving like it should.

On 1/21/26 traveling on a 4 lane divided highway, vehicle stalled, several warning lights came on and vehicle came to a complete stop in driving lane. Vehicle locked in park and could not put vehicle in neutral to push it out of highway. Several vehicle swerved to avoid and until tow truck came blocked a lane. It was about 3:30pm fortunately. So vehicle was visible and no accidents to our knowledge occurred. Thai created a dangerous traffic situation. It was caused by a fuel pump control module Whig was repaired 2 days later at local Chevy dealer. We were advised there were no recalls on this part but it is a common problem. GM should somehow find a solution and repair said problem

September 2025; the fuel control module failed at 75 mph in the left lane of I-45 requiring me to pull over on the shoulder in heavy traffic. I eas towed to my dealership 170 miles. At that time the recall test was performed on my 6.2 L L87 engine and passed inspection. The oil was upgraded at that time. Jan. 3, 2026 at 65 mph the engine died, once again on the highway at over 65 mph. Again I struggled to get to the right shoulder in heavy traffic. At the moment of failure, the engine revved from 1500 rpm to 3900 rpm and instantly fell to zero rpm and died. A message on the dash read unable to put in vehicle neutral. Again, I had it towed to my dealership where it's been diagnosed with a seized engine and I'm waiting (three weeks so far) on an engine replacement. I'm told the manufacturer rep has been to the dealership to confirm the failure and approved a complete engine replacement. There was never any advanced warning appearing on the dash. I have thorough maintenance records on this vehicle.

The motor blew with no notice, around 1000 miles after the recall inspection. My safety, along with the others around me was put at risk as I was in the fast lane during rush hour traffic with no motor to aid switching lanes to get to the shoulder. Finally died at one of the busiest intersections in the state, for the last time, as I was attempting to limp to the dealer via multiple restarts. leaving me stranded on the side of the road on a wonderful January day. The vehicle has been inspected by the dealer and slated for an engine replacement. No notice, I let off the gas, and when I went to accelerate again, the motor shut off.

Dear Sir or Madam, I am writing to formally report a safety-related defect involving the power unlatching tailgate switch on my Chevrolet 1500 truck and to request that this make and model be added to the current safety recall affecting Chevy HD vehicles. The power tailgate unlatching switch malfunctioned and would repeatedly attempt to open and close the tailgate while the truck was parked. On one occasion, this occurred continuously overnight. The following morning, my key fob was completely unresponsive, and the truck had zero battery life. The battery would not accept a charge, and the vehicle had to be towed to the dealership. Upon inspection, the dealership confirmed that the battery had been fully depleted and permanently damaged due to a short in the power tailgate switch. The faulty switch continuously drew power as it attempted to actuate the tailgate, ultimately destroying the battery. This failure created a serious safety and reliability concern, leaving me stranded with a completely inoperable vehicle. Given that this issue resulted from an electrical short and caused total battery failure, I believe it represents a significant safety defect. Based on the similarity to issues addressed in the current Chevy HD safety recall, I strongly believe this make and model should be included in that recall. I respectfully request that this matter be reviewed and addressed to prevent other owners from experiencing the same hazardous situation. Thank you for your time and attention to this matter. I look forward to your response. Sincerely, Charles Senn

Can shaft and lifters failed

General Motors sent me a letter regarding a safety recall regarding my 6.2L V8 gas engine (ROP L87). Safety recall N252494000. I learned that my truck has the potential to have a complete engine failure. I took my truck to the dealership and all they did was an inspection and changed the oil on it. I'm not a mechanic, but total engine failure is concerning to say the least. I doubt simple change in oil thickness remedies serious recall. I learned there is an open lawsuit regarding this issue. I need Chevy to take this matter more serious, Im driving my family around in a ticking time bomb. I demand more than a band-aid. I want Chevy to replace my engine with a new reliable one.

While driving at 70mph, my vehicle spontaneously shifted into Neutral and therefore dropped power to the transmission. I was unable to shift out of Neutral and therefore had to coast to the shoulder. Upon coming to a complete stop, my truck independently shifted into Park. Again, I was unable to shift out of Park. I turned my truck off, let it sit for a few seconds before unsuccessfully attempting to restart my vehicle. Multiple attempts to restart my vehicle continued to be unsuccessful and the vehicle system would reboot then shut off.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the tailgate was constantly opening unintendedly. The failure also occurred while the vehicle was parked overnight, causing the battery to drain. Additionally, the contact stated that the rearview camera was inoperable. The vehicle was taken to the dealer, where it was diagnosed, and determined that the tailgate switch and rearview camera had failed due to water intrusion. The dealer replaced the tailgate switch; however, the rearview camera was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 38,000.

My vehicle was part of the recall N25494000 L87 Engine loss of propulsion. Vehicle went in for recall on Sep-30th 2025, PicoScope Inspection was done and vehicle passed. Oil was changed to 0W 40 with new oil filter. Dec-26/27 of 2025 vehicle started stalling, for no reason but no Engine light. The dealer said there was no problem because there was no engine light, so there was no way to find out what was wrong. January 11th 2026 vehicle lost propulsion 7 times on the freeway, vehicle had a hard time re-starting and started smelling oil burning smell. Vehicle Engine light stayed on, 1/11/2026 vehicle was running a little rough with abnormal tapping noise but made it to the dealer for inspection.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING), but the failure occurred. The contact was informed by the dealer that the vehicle had passed inspection, and the dealer added a higher viscosity oil, installed 6 oil fill caps, and replaced the oil filter. The contact stated that six months after the vehicle was repaired, there was an abnormal squeaking sound coming from the engine. The contact stopped at a gas station to refuel. Afterwards, the vehicle failed to restart, and there was smoke coming from under the hood. The contact stated that the engine had seized. The contact was at the gas station when the failure occurred. The vehicle was towed to a dealer; however, no cause for the engine failure was found. The contact was informed that the sound was coming from one of the drive belts. The vehicle was not repaired. The vehicle was then towed to another dealer, where it was diagnosed and determined that the abnormal sound was coming from loose bearings in the engine. The contact was informed that the engine needed to be replaced. The long block in the engine and the radiator were replaced on January 1st. The contact stated that a week after the vehicle was repaired, the vehicle failed to start. After several attempts, the vehicle restarted. The vehicle was taken back to the dealer. However, no cause for the failure was found. The dealer recharged the battery. The contact stated that shortly afterwards, the vehicle failed to start. The vehicle was taken back to the dealer, where it was diagnosed and determined that the starter had failed. The contact requested that the dealer check the ground strap, but the dealer refused. The vehicle remained at the dealer unrepaired. The contact stated that the dealer would notify the manufacturer of the failure. The approximate failure mileage was 44,469.

Tail gate has water intrusion and opens on it own. I was charge over $200 to have this issue looked at that I was told was a recall. Turns out my vehicle is not listed on the recall yet and was not advised before being charged.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while depressing the brake pedal to come to a stop, the contact heard an abnormal metal-to-metal sound coming from the front passenger-side brakes. Additionally, the vehicle was delayed in responding, causing the braking distance to be extended. The check engine warning light was illuminated. The contact stated that the dealer had replaced the front passenger-side brake calipers, rotors, and pads at approximately 19,000 miles. Additionally, the dealer had determined that the front driver-side brake pads had worn down to the metal at 20,000; however, the cause of failure was not determined. The front driver-side brake pads, caliper, and rotor were replaced. The contact stated that while coming to a stop on a separate occasion, an abnormal metal-to-metal sound could be heard coming from the front passenger-side brakes while the brake pedal was depressed. No warning lights were illuminated. The vehicle was taken to the dealer, but the vehicle was not repaired. The contact stated that the dealer refused to repair the vehicle. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure.  The failure mileage was approximately 29,000.

While driving the vehicle the tailgate came open by itself. I had left my house and when I arrived at my friend’s house to pick him up the tailgate was down. I closed the tailgate and while driving a driver honked their horn to alert me that something was wrong. When I pulled off the road the tailgate had come open for a second time.

The vehicle 'turned off' while in motion at around 35-40 mph on a busy 5-lane major arterial road in the city on 12/21/2025 at around 0630-0700 hours. Driver (author of this report) was able to turn into a side road and stop. Message "Press start button" displayed on dash panel. Complying with this action led to a coughing start but vehicle could not be put into drive mode because a second message appeared saying "Conditions not safe for transfer". Eventually over next minute or two vehicle coughed up to a start again and was able to put into drive mode and drive to parking garage to safety. Driver was able to drive back about 3 hours later with no recurrence or new malfunction. No warning lights throughout the episode. My Chevrolet mobile app also did not display error messages. Vehicle was driven (without incident) and delivered to a Chevrolet dealer on 12/24/2025 for diagnostics and workup and is currently situated there.

My tailgate latch keeps opening every 60 seconds. Does it going down the road or parked. my tailgate has hit numerous cars that parked behind me causing me to have to pay out of pocket for 2 other cars where my tailgate dented or scraped the paint on their vehicles. I see this safety recall online for this tailgate latch, but my vehicle isn't covered for some reason. Safety recall N232426400 explains the entire issue with the faulty latches. Due to the faulty latch, now my tailgate also needs bodywork and to be repainted. That's costly.

Yesterday I was driving and the pickup truck put itself into neutral and died in the middle of the road and almost got rear ended with my kids in the car. The car would not start again and no codes were given.

I have an 2023 L87 engine that could stop functioning at any moment. I'm retired and bought this vehicle as my last truck. I don't feel safe driving it on long trips which is why I bought it. Also the transmission shifts rough from 1st to 2nd when I accelerate. When I inquired about the transmission problem at the dealership the showed me a letter sized notice saying this might be a problem. But I was not notified about this when I purchased the truck. I would prefer to just return the truck as I have it financed with GM Financial with no money down and am willing to just eat what I have already paid to get out of this ticking time bomb which I'm not comfortable driving long distance as [XXX]. Please advise. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

was crossing an intersection when the truck suddenly and without warning stopped (engine). Unable to shift the truck into neutral in order to move the truck out of the flow of traffic. This is because the truck has the electronic shifter which requires the truck to be running in order to shift. There is not a manual override. So basically the truck was in the middle of an intersection with cars and trucks weaving around it until the tow truck arrived. But since the truck wasn’t able to be shifter into neutral the tow truck had to maneuver around to the front and “drag the truck onto a flat bed in order to clear the vehicle. Also it turns out that there is a major issue with the fuel pump module on these trucks and the tow truck driver said he has seen this happen a lot and very common. As a result these types of issues are likely to result in a near of fatal accident in the near future.

While driving at highway speeds, in traffic, all dash lights lit up and the engine shut off. The truck began decelerating on its own, I couldn’t brake and could barely steer. Luckily I was going fast enough that I managed to coast about a hundred feet to get partly out of traffic. The truck would never start again and I had to wait for 7 hours for GM roadside assistance to tow me to a Chevy dealer that was 4.6 miles away. 23 hours later the dealer called me and told me the starter caused the problem, in which I told them made no sense. 30 mins later they called and said the motor failed due to recall N252494003 for the L87 engine. My truck had passed the recall inspection for this recall on Sep 24th, 2025 and received the new oil that was supposed to prevent this failure. I had also just had the oil changed again around Nov 13th because the FCW module needed a firmware update and was not functioning. The truck had given NO warning or issues previous to Dec 3rd.

I was driving my vehicle when the check engine light came on and a message then came across the screen and stated the truck would no longer shift if I didn’t stop driving it. I took It immediately to Autonation Chevrolet Service on Nov 9. I received it back on 11/26 my service advisor said it passed inspection that no work was completed I needed to use high synthetic oil and filters for my truck to keep it going. This doesn’t sound correct when I’ve owned several Chevy/GMC trucks. I only have 33k miles on my truck and want the recall fixed. Please help me get this taken care of.

GPS system behaves erratically. (Position jumps around). Phone gps very stable. While using navigation in the truck the jumping position causes the map to jump and swing also it lags behind missing turns etc. This is proving to more of a distraction making me look at the map longer. I tried dealership and they said it works while I have video evidence of its behavior. I will try another dealership but maybe thousands of others are having same issue and this help to force a fix.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, and attempting to slow the vehicle, the brake pedal required an increased effort to slow the vehicle, and the vehicle required an increased distance to come to a complete stop. The vehicle returned to normal functionality, but the failure became a regular occurrence. The ABS warning light was illuminated. The vehicle was taken to the dealer, and the contact was informed that a failure could not be determined as the vehicle was functioning as intended and that no warning lights were illuminated during the time at the service center. The vehicle was not repaired. 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 17,000.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the engine was running rough. The message "Service ECM" was displayed. The vehicle was taken to Auto Zone, where diagnostic trouble codes displayed fuel injector misfiring on cylinders 1 and 4. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

OnStar Module needs to be replaced and of course the module died right after the warranty went out. After research come to find out this is an issue with all GMC and Chevy vehicles

Please see attachment:

While driving and idling, my 2023 Chevrolet Silverado 1500 High Country equipped with the 6.2L v8 engine began experiencing a persistent audible ticking/clicking noise from the engine bay, rough idle during cold starts, and noticeable/abnormal engine vibration. Shortly after, the check engine light came on. When scanned, diagnostic codes P0304 (Cylinder 4 Misfire Detected) and P050D (Cold start Rough Idle) were retrieved. The vehicle was inspected by an authorized Chevrolet dealership, and the service advisor and technician confirmed hearing a consistent clicking noise and documented that they contacted GM's Technical Assistance Center (TAC case #80413912). The service order report states: "Due to unknown noise cannot perform recall. Called TAC 80413912 and was told need to figure out top end noise and misfire before proceeding with recall. If repairs are related to top end, will not be covered under recall." The technician indicated this could be related to a camshaft and lifter issue, which matches the symptoms outlined in GM's active propulsion system recall for 6.2L engines. Suggests GM aware & has not yet confirmed full recall coverage/repairs. This issue presents a significant safety risk because the engine could experience sudden power loss or failure while driving, potentially leading to loss of propulsion or control. These symptoms are identical to those described by GM in their recall documentation concerning valve lifter and camshaft failures. The issue has been reproduced and confirmed by the dealership, and all documentation, diagnostics reports, and service notes are available for inspection upon request. Warning/check-engine lights first appeared in October 2025, and the problem persists. Based on GM's recall acknowledgment of similar failures, I believe this defect should be fully covered under the existing recall, and I am requesting NHTSA's review to ensure manufacturer addresses this safety-related defect promptly and without cost to owners.

1.Coolant control valve failure 3 times within 125,00 miles causing the engine to run hot without overheating indication, losing heater and defrosting capabilities unable to operate safely with windshield freezing, 2. in addition this also caused the engine to run hot enough to burn manifold gasket and cracking manifold creating carbon monoxide to enter through cab vents. $4500 repair cost-that in order to operate safely. 3. Finally on star safety features not available due to module battery dead only after 2 years gps,emergency call and everything else included in this safety feature unavailable $1,000 cost manufacturer or dealer will not recognize any of these due to warranties and expiration.

Driving at highway speeds, truck downshifted to low gear causing a sudden deceleration and check engine light appeared along with 'Service Transmission' message. Was almost rear ended by multiple cars, but was able to guide truck to the shoulder through traffic. Shut down truck and restarted with message still appearing although gear shifting seemed to be normal. After stopping at a gas station to look up error, on next restart error cleared and truck drove for almost a week without issue and ~300-400 miles. Once again driving at highway speeds the same scenario happened with downshift in heavy traffic and had to pull to the shoulder. Waiting to bring to dealer, but mileage on truck is just over the 60,000 mi warranty period. Codes on reader indicate P0700 and P0747.

I WAS DRIVING ON THE HIGHWAY DOING 75 AND THE TRUCK STARTED JURKING AND SLOWING DOWN BY ITSELF AND GETTING LOUD. THE DISPLAY STATED REDUCE SPEED AND THE CHECK ENGINE LIGHT CAME ON..

Vehicle vehicle is shuddering while driving at speed limit as well as accelerating. Based on research, it is apparent that there is an issue with the torque converter in this year model of truck. I have found more than 50 individuals online who have dealt with the same issue.

Truck shut off as I was driving. NO Warning. On a hill poor visibility Gratefully no injury. Required tow truck to dealer. Just received statement REPLACED FUEL CONTROL MODULE. Vehicle has 14000 miles Cost was covered by warranty but this should not have happened! Warranty does does not cover how shaken as I am a senior driver trusting this truck.

Sometime between backing into my parking spot at work, then backing into a parking spot at the dentist, My Tailgate released/lowered. When I backed in at the dentist, my back up camera seemed to malfunction, so I just used my mirrors. Apparently, the camera was just pointing at the ground. Sine you can't see your tailgate in the mirrors; I could not see that it hit the retaining wall at the back of the space.

It burns a significant amount of oil. I had an oil consumption test completed with a GM dealership, they state it is in their guidelines of standard. It burns around 2 quarts of oil within 5000 miles, so between oil changes. The add oil alert popped up while I was driving down the highway. My truck has 33500 miles on it, it should not be normal for a new truck to burn that much oil. They will not check my engine to identify the cause because they state it is within their standards.

Driving down the road and the engine turns off with no warning lights, noise, or any indication of an issue. I was luckily able to use momentum and move to the side of the road. The Chevy dealer has inspected the engine and concluded that the engine is blown.

I am filing a complaint regarding a potential recurring safety defect related to Recall NHTSA 25V274 (GM N252494001). On July 29, 2025, my vehicle stalled while driving on the highway and was towed to Quality Chevrolet. The dealer diagnosed a failed starter and battery fuse link. During this visit, I authorized inspection for Recall 25V274, concerning possible crankshaft or connecting rod failure. I was told my vehicle was not affected but the dealer performed the recall remedy by changing the oil to 0W-40. On October 5, 2025, the vehicle developed a loud knocking noise from the engine. Quality Chevrolet diagnosed a connecting rod failure, the same issue identified in the recall. On October 10, 2025, I was advised that GM approved a full engine replacement due to internal damage. However, I was also told the new engine will use lower viscosity 0W-20 oil, contradicting the prior remedy intended to prevent this failure. This suggests the original recall fix was only a temporary measure, and the defect remains unresolved. I request that NHTSA investigate whether the current recall remedy adequately corrects this safety issue and whether GM’s use of 0W-20 oil could allow repeat failures. Additionally, I request assistance or reimbursement for vehicle payments, as my vehicle has been undrivable for an extended period due to a manufacturer defect. Thank you for your time and attention. I can provide all service records and diagnostic reports upon request.

While driving at low speeds with light acceleration, the truck seems to sputter. When activating trailer mode this issue stops leading me to believe there is an issue with the torque converter. By searching forums, this seems to be a known issue with these vehicles. With it being as widespread as it is, I fell like this constitutes some sort of recall or customer satisfaction type of action.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while pulling into a parking space and turning the steering wheel to the right, the vehicle surged forward going up onto the curb, and the contact depressed the brake pedal; however, the vehicle failed to stop. The contact continued to depress the brake pedal however, the vehicle continued driving approximately 5-10 MPH. The contact shifted into neutral(N); however, it was too late, and the vehicle crashed into another parked vehicle before coming to a stop. The contact stated that during the failure, the braking system had malfunctioned while depressing the brake pedal. No injuries were reported. A Police report was filed at the scene. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The contact stated that one week before the failure, at almost the same spot, while driving at an undisclosed speed, the Forward Collision Avoidance warning light illuminated and remained illuminated without another vehicle being nearby. The contact turned off the vehicle, exited the vehicle and inspected the vehicle before re-entering and restarting the vehicle, and the Forward Collision Avoidance warning light remained illuminated. The contact turned and restarted the vehicle and the warning light was no longer illuminated. The manufacturer was notified of the failure. The failure mileage was approximately 11,000.

My telematic control module has intermittent connectivity. The check engine light comes on and off and the go's, on star and wifi comes and goes as well. This vehicle has 52k miles on it and is only 2 years old. The shop I took this to said it is VIN specific so the dealer is the only place that can fix it. This is a safety issue due to no onstar as onstar claims to be a safety feature. This needs a recall because this issue is all over the place on gm products.

I was traveling when on my dash came up "software update available" so I looked at how to and said truck will need to be off for 15 minutes during software installation so I decided to wait until I got home from trip. So on the moring of October 2, 2025 did the software update in my driveway. Then in the afternoon needed to go somewhere and I saw the service engine warning symbol on dash. Went to where I needed to go, 4 miles from home. Then when I was finished headed home and on way home warning on dash came up, "Service Transmission Now Unable to Shift Soon". So I got home and made some phone calls and ended up taking truck into Polar Chevrolet, White Bear Lake, MN. Thursday before they closed. Friday October 3 got a call from Polar Chev and issue is "Gearshit control module", part number 86515985. But was told part was out of stock and could take 1 week or even upto 1 month for them to get part. Looking on internet did see that this warning has come on from other people right after they did the software update. Needless to say my estimate for repair is going to be somewhere form $900 - $1000. So now have to wait and see when they get part and if it is actually issue.

The 2023 Chevrolet Silverado 1500 High Country has experienced multiple powertrain and transmission failures beginning shortly after purchase. The issues include violent shifting, hesitation, and stalling, particularly while accelerating or decelerating. These malfunctions create serious safety risks—especially when merging, turning left across traffic, or entering intersections. The truck has been returned to authorized GM dealerships multiple times for diagnostics and repair. GM service departments confirmed transmission faults but have not successfully resolved the issue despite repeated attempts. The same problems reoccur shortly after each repair. At times, the vehicle has entered “limp mode” unexpectedly while driving, causing a loss of power. On at least one occasion, this occurred while driving on a busy highway, forcing evasive action to avoid a collision. Warning lights such as the “check engine” light and service alerts frequently appear before or during these incidents. To date, the vehicle has been inspected by GM-certified technicians at authorized dealerships. A case has been opened with GM customer care and BBB AUTO LINE arbitration has been initiated. The truck remains unreliable and unsafe to operate, especially with children on board. The risk of sudden power loss or drivetrain malfunction poses a clear hazard to occupants and other drivers.

Date of Incident: [XXX] Approximate Time of Incident: [XXX] EST Location of Incident (City and State): Tallahassee, Florida Street or Highway Name: [XXX], lane between [XXX] & [XXX] Weather Conditions: Clear and dry, approximately 90°F While traveling at approximately 72 MPH in the center lane of [XXX] westbound near Tallahassee, FL, the vehicle suddenly began rapidly decelerating after shuttering, as if the brakes were being applied without driver input. A warning message appeared on the dashboard instructing the driver to restart the engine. At the same time, the steering and brakes became noticeably stiffer, suggesting that the engine had shut down. The driver navigated across high-speed traffic, nearly avoiding being rear-ended by other vehicles, and was able to bring the vehicle to a stop on the shoulder. Multiple attempts to restart the vehicle were unsuccessful. The incident posed a serious safety risk due to the loss of engine power and driving assist features in active interstate traffic. After the incident, the vehicle was towed to Dale Earnhardt Chevrolet (3127 W Tennessee St, Tallahassee, FL 32304), where it is scheduled for inspection on or after Monday, September 30, 2025. The dealership may retain the faulty part(s) and the vehicle is available for further inspection upon request. No prior warning lights or symptoms were noticed before the incident occurred.

See attached document for complaint.

The contact owns a 2023 Chevrolet Silverado 1500. The vehicle was recently repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact understood that the option was to use a higher viscosity oil, replace the oil fill cap, and oil filter replacement. The contact stated that the remedy was insufficient to resolve a possible failure with the engine. The contact was hearing abnormal ticking sounds coming from the engine after starting the vehicle in the morning since the recall repair. The contact stated that once the engine had warmed up, the ticking sound ceased. There was no warning light illuminated. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The contact had not experienced a failure with the engine.

The vehicle has been exhibiting occasional hard shifts over the last 2-3 months. Over the last 2-3 weeks the frequency has increased. While operating the vehicle at approximately 30 mph the rear wheels temporarily locked during one of these events while my wife was operating the vehicle. There was no indication that this was going to happen and no indication after the event. We took the vehicle to the dealership where they performed a diagnostic but found nothing wrong. In the week since picking up the vehicle I have been operating it. I experienced two occasions where upon trying to accelerate at approximately 30 mph there was a severe jolt that caused the traction control warning light to flash. This was under minor acceleration just to maintain speed when going uphill. There was no indication prior to the event and once it had concluded the lights went off. I also experienced an occurrence of the rear wheels locking temporarily. I was traveling at approximately 40 mph on flat ground and gently stepped on the accelerator to maintain my speed in traffic. The rear tires locked for 1-2 seconds to the point the tires were squealing and you could smell burning rubber. There was no indication prior to the event that it was coming. Given my necessary reaction I was unable to see if there were any indicators or warnings present. Following the event there were no indicators illuminated. Outside of these events the vehicle seems to operate normally. It runs well and generally shifts smooth. However, the rear wheels locking up unexpectedly presents an unacceptable hazard that is not resulting in any evidence that the dealer can use to troubleshoot.

Over the past 4–6 months, the transmission in my 2023 Chevrolet Silverado 1500 has repeatedly failed in a way that creates a serious safety hazard. On multiple occasions while driving at highway speeds, the transmission has locked up the rear end, causing a sudden and violent loss of control. These incidents nearly resulted in collisions and could have caused serious injury or death. The truck will no longer shift at all and is now completely inoperable. These failures happen without warning and present a severe risk of total loss of vehicle control. Date(s) of Incident: Multiple occurrences between approximately March 2025 and August 2025 (exact dates unknown). Dealer / Manufacturer Response: I contacted Chevrolet Customer Care and multiple Chevrolet dealerships in my area (including John Megel Chevrolet, Dawsonville, GA). My most recent case was closed without resolution. I have been denied a loaner or reimbursement for a rental vehicle, and I have been told that the repair could take at least a month before even being assessed, with additional delays for parts. Consequence: This is not only a serious safety hazard but also a severe financial and employment hardship. I rely on this truck for my job, and without it, I cannot work. I am now three months behind on my truck payments and other bills, and I am on the verge of losing my job because I have no transportation. GM’s failure to repair or provide alternate transportation has left me stranded, financially unstable, and at risk of unemployment — all while the vehicle remains under an extended warranty. Request to NHTSA: I am requesting that NHTSA investigate whether this defect is part of a wider safety issue affecting 2023 Chevrolet Silverado 1500 transmissions and determine if a safety recall is warranted.

Engine coolant valve failure causing vehicle to go into reduced power mode while traveling on highway causing vehicle to travel at a slow unsafe speed in relation to other traffic. Check engine light activated, reduced power activated. Chevrolet dealership confirmed engine coolant control valve issue. Engine control valve must be replaced before vehicle can be driven. Engine Coolant control valve is on back order. No part replacement time frame due to back order. Safety concerns with reduced power mode on roadway with speed limits greater than 45 mph.

We bought 2 of the same exact trucks last year. They each had no miles on them. My business partner was coming home from vacation and stated hearing ticking. We took it to our mechanic and he said it’s a blown motor. Prior to leaving for vacation, an oil change was done on the truck. When the mechanic said the motor is blown he also said it’s down 3 quarts of oil. All scheduled maintenance was done on the truck routinely. We took the truck back to the shop that did the oil change and they had recorded the service, there was no doubt the oil was changed the prior week but it was now black and down three quarts.

Vehicle check engine light came on and message displayed on dashboard indicating (loss of power) the transmission fluid temperature rose from 140* to 190* in seconds with vehicle coming to a complete stop while driving when trying to accelerate the vehicle it won't move but the engine rpm's were staying between 3 & 4 when accelerating.

I have a 2023 Chevy Silverado 1500 3.0L Duramax Trail Boss. Temperature gauge keeps flocculating, engine fan kicks on at 100% and shuts off the AC. Warning on dash engine temperature to high AC shutting off and engine over heat. Took it to the dealership for the truck is still under warranty. They diagnosed it as a faulty coolant control valve. Was told it was safe to drive by the technician but I question that. Dealership ordered the part four weeks ago and it still has not come in. When I inquired about the delay, I found out it is on back order and the availability of the part long wait time. Further research found that this is a systemic issue owners are having with this specific engine since 2020. Yet GM has not done a recall nor is there supply stockage of this part, seeing how this part commonly fails.

While driving 55 mph and towing my boat on a 2 lane paved road , I started up a slight incline and the transmission downshifted so hard that the rear wheels locked up long enough to throw us into the dash even with seat belts on. I turned around an drove back home with it locking up again. No codes or lights on the dash. Took it to dealer June 26,2025 for dealer to diagnose issue. They kept it overnight and drove it about 60 miles, called me the next day to pick it up saying they could not duplicate the rear wheel lockup and since there were no codes there was nothing to fix. Tried to tell me it was my boat trailer causing the issue. Boat trailer has surge brakes, nothing electrical on trailer brakes. Over the next couple days the rear wheels locked up 2 more times. Always as I started up an incline going around 50-55 mph. No lights or codes July 2, 2025 we recorded on video 2 rear wheel lockups with the second lockup starting a slight fishtail on dry pavement and leaving a 5 foot skid mark. Went back to the dealership with the video and they said again if there are no codes they can’t fix it and they would try to duplicate the issue for me to leave the truck and not give me a rental vehicle , and no timeline on how long they would try to duplicate the issue. I did not leave my truck there and they kept promising to call me when they had a loaner vehicle for me to use. On July 14, 2025 ,while still waiting for a loaner vehicle the transmission finally locked up the rear wheels and check engine light came on. My mileage was 43078, it took 1,193 miles to finally throw codes that the dealership would fix. Codes were P0700 and P0747. These are same codes for safety recalls N242454440 and N242454441. Obviously my vin is not included in the recalls but the dealership should have put the software on my truck the first time I was there on June 27th, the same day they completed the Pa.state inspection on my vehicle. I wouldn’t have had to experience this unsafe conditions.

Transmission has a stalled while driving car

The fuel pump went out, left me stranded and was replaced The transmission went out and was replaced. The lifters in the engine were replaced. When will the engine recall be addressed/acted on? The "cure" to install heavier engine oil is a very bad "bandaid"....truly masks the problem. Maybe the Chevy CEO should return her 2024 $25mm bonus to help pay for the repairs.

The contact owns a 2023 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The contact stated that while driving 65 MPH uphill, the check engine warning light illuminated. The contact pulled over to the side of the road and turned off the vehicle. The contact was able to restart the vehicle after waiting for several minutes. Additionally, the contact stated that vehicle was idling rough while driving. The contact stated that the rough idling persisted. The vehicle was taken to the dealer but was not diagnosed or repaired because the recall repair part was not available. The contact scanned the vehicle with a diagnostic code reader and retrieved DTC: P0016, which indicated that the powertrain control module (PCM) had detected that the crankshaft and camshaft were not synchronized. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact had safety concerns while driving the vehicle. The failure mileage was approximately 49,500.

THIS TRUCK HAS A PROBLEM WHERE AT LOW SPEED WHILE TURNING LEFT THE ENGINE SURGES AND THE TRUCK SPEEDS TO 15 MILES AN HOUR UNLESS I JAM ON THE BRAKES . THIS STARTED JUST TURNING LEFT AND NOW ITS STARTING TO HAPPEN TURNING RIGHT . I HAD THIS TRUCK TO KOONS CHEVOLET TWO OR THREE TIMES FOR THIS PROBLEM BUT IT STILL PERSIST TO HAPPEN. THIS VEHICLE IS DANGEROUS.

I have had to replace 2 batteries due to the tailgate opening and shutting randomly even when parked, and ruining my batteries. You recalled the 1500 HD's for the same issue... but yet not this model when it's clearly happening to 1000's. I'd appreciate it being fixed

The contact was notified of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. While driving 55 MPH, the vehicle stalled with an unknown message displayed. Due to the failure, the vehicle was towed to the dealer. Several days later that the dealer informed the contact that a new engine had been ordered and the new engine was replaced. The contact stated that after retrieving the vehicle, there was an abnormal knocking sound coming from the vehicle. There was no warning light illuminated. The dealer was notified of the failure and an appointment was scheduled to have the vehicle serviced. The contact stated that while in a store parking lot, the vehicle failed to start after several attempts. Due to the failure, the vehicle was towed to the dealer where the mechanic discovered that a fuse connector was loose, causing the failure to start. The contact was also informed that the dealer failed to replace several screws and bolts back in place once the engine was replaced. The vehicle occasionally surged forward or hesitated while depressing the accelerator pedal, causing the contact to lose control of the vehicle while driving at various speeds. The manufacturer was made aware of the issues and the contact was informed that a refurbished engine was placed inside the vehicle and not a new engine as the dealer had stated. The vehicle remained with dealer due to safety concerns. The vehicle was not repaired. The failure mileage was approximately 26,000.

I am filing this complaint against General Motors (GM) and its affiliated dealership Kunes Chevrolet for the unauthorized installation of a surveillance/tracking device (LoJack) in my vehicle, which resulted in severe personal harm, digital exposure, and downstream targeting. On [XXX], I purchased a 2023 Chevrolet Silverado from Kunes Chevrolet in Morrison, Illinois. I was never informed that a LoJack tracking device had been installed in the vehicle. On [XXX], I appeared in person at the same dealership to confront suspicious activity tied to my vehicle’s GPS data. A service advisor confirmed the presence of a LoJack unit and printed a removal ticket, which should be recorded in GM’s internal service system under my name and VIN. This constitutes verifiable, documented acknowledgment of the unauthorized installation. Consequences of This Violation Include: •Illegal geolocation tracking without consent •Suspected sale or exposure of my driving data to third parties and possible defense-linked contractors •Multiple impersonation attempts, including suspected social and professional infiltration •Psychological harm, loss of employment, opportunities, and repeated digital sabotage •Multiple homicide attempts on my life •FOIA-confirmed military interest in my location (Air Force Case #: [XXX]) •IRS and identity manipulation, suggesting systemic misuse of my physical address, GPS logs, and digital footprint INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Occasionally, from the time the vehicle is started to a while after shutdown the left front turn signal / DRL / parking light does not work. Upon turning on the left turn signal, the driver information center says check left front turn signal lamp. The rear turn signal flashes rapidly and the front doesn't illuminate. I've had the vehicle to the dealer 3 times and counting. Twice they confirmed the problem. Wires were inspected and a connection to the turn signal assembly was greased and researes. The next step is to replace the turn signal / headlight assembly.

The vehicle is now at the dealer for the second time regarding transmission shifting issues. First visit I was told they can find nothing wrong despite my experiencing transmission slipping, loud clanking on shifting, and severe jolting when shifting. While having a travel trailer hitched to the truck after the first visit, I experienced all the same issues with the addition of transmission overheating warnings on the dashboard and near complete stoppage of the vehicle at highway speed. The same dealer now says the transmission "valve body" is defective and is being ordered. Due to Towing a trailer with this truck (much lighter than rated capacity) I have the transmission fluid changed on nearly every oil change. The Transmission filter has been changed on the recommendation of my mechanic, strictly due to quantity of fluid changes.

The vehicle began making a loud fan noise in the engine after the summer began (06/2025) and the temperature gauge was elevated but not by a concerning amount. After an oil change (06/21/25) we were told that it was normal because of the weather. A week after the check engine light was coming on intermediately (began 06/28/2025) depending on the day and the temperature outside (we are currently in the middle of a heat wave). The vehicle was taken to the dealership (07/02/2025) where they determined that the coolant flow was too low and found that the engine coolant pump is faulty and needs to be replaced. f the coolant is low in a Chevy Silverado and the engine overheats, it can lead to significant and potentially expensive engine such as a blown head gasket, cracked engine block, or even a complete engine failure or fire.

I was driving on the freeway and smelled gasoline in the cab. I thought nothing of it as I was near a wreck and thought it was from that. About 10 miles down the road I was stopped in traffic and noticed my miles until empty was slowly declining as I was stopped. When I moved forward there was a puddle under my truck. I pulled to the side of the road and fuel was draining from the back of my engine all over the exhaust. I immediately shut the truck off. I cannot believe the gas didn't ignite as those catalytic converters get well over 536°. The truck was towed to the closest Chevrolet dealer over 10 days ago and I have YET to hear anything from them. I bought the truck used from another Chevrolet dealer 3 weeks prior, and it has had the L87 recall.

No remedy available putting myself and my family at risk.

I been to the Chevy dealership a few times for the 6.2 L recall that I have and I keep getting turned away

So I experienced a P1098 code in my 2023 Chevy Silverado with a 3.0 liter Duramax. When you get this code the truck will go into “limp” mode with reduce (nonexistent) acceleration and only go to about 60 miles per hour (63) I think. This could become a large safety issue if someone was to experience this going down the highway. It is also a VERY common problem doing internet searches. Seems that GM knows this is an issue but does nothing about it. In fact they even tried to remove the part from warranty because it was happening so often. Seems like this is something the government should look into and see what the true cause of the issue is. On the other hand some of the reliability of these engines is caused by the government implementing many restrictions on the manufacture to meet certain requirements. I am frustrated this happened along with probably with thousands of other owners. Thanks!

I own a 2023 Chevrolet Silverado 1500 ZR2 equipped with the 6.2L V8 L87 engine. My vehicle is included in Recall Number 25V274 / N252494000, which addresses manufacturing defects in the connecting rods and/or crankshaft that can cause engine failure. My recall status currently shows: "Recall Incomplete, remedy not yet available." However, GM and NHTSA have already stated the remedy: a VIN-specific engine inspection, followed by either a replacement or an oil system update and extended warranty. I contacted my dealership, Lochmandy Chevrolet in Elkhart, Indiana [XXX] ), and was told on June 1, 2025, that they could not inspect my truck due to lack of tools or VIN clearance from GM. I was given no estimated timeline for when I can get my vehicle serviced. My concern is that I’m driving a known defective vehicle with a potential for sudden power loss or engine seizure—a serious safety hazard. My truck currently has 19,500 miles, and I’m worried about continued use without an inspection or remedy. I’m requesting that NHTSA follow up on GM’s delays in remedy deployment, ensure dealerships are equipped for inspections, and provide vehicle owners like me with a firm timeline for repairs. Please open a case and provide a reference number. I can be reached at [XXX] for updates. I am documenting all interactions with GM and my dealership for safety and legal purposes.

While driving down the road I let off the accelerator to start applying brakes for a red light I was approaching, then the vehicle shut completely off and down shifted hard. After that it restarted a second later but had no power steering and no brakes. At this point I was approaching the red light with no brakes and power of my vehicle, the other traffic had a green light now and was crossing my lane of travel but I was luckily able to make it through the light in between vehicles without causing any harm to myself or others. After making it through the light I was rolling 10mph still helpless but seen a gas station on my right and rolled into their parking lot and drove towards a curb and used the curb to stop my vehicle. The vehicle had the following warning lights and messages: Lane Change Alert System Off, Brake system failure 62mph top speed, service traction control, service ESC, and trailer brakes disabled service required. I then got the vehicle towed to the dealership while still on and in the running position with all the codes still active. The dealer was able to scan the truck in and see the codes but told me they wouldn’t be able to get to it till the following week so they parked the vehicle and turned it off. When they got to my vehicle the following week they sent me a text and said I quote “Hey ****** its **** from Chevy, I do not have the best news lol he can not get it to act up and there are no current codes he has driven and nothing has happened, as of now there is nothing further he can do”. After receiving that text I called them to just be told they can’t get it to do it again and there is nothing they can do. But I told them I refuse to pick up this vehicle because it had a critical safety issue. This vehicle suffered a catastrophic failure, brakes and steering were lost in an intersection. If not diagnosed properly, this poses a threat to life.

Everyone I know that has this trucks has had transmission problems now mine is say selanoid is stuck in transmission but it throws a new code every time same issue

On [XXX] the automatic tailgate on my 2023 Chevrolet Silverado began opening and closing without reason. This obviously poses a potential safety issue. After investigating, I found that there is a recall on 2020 to 2024 Silverados, recall # N232426400. I called Penske Chevrolet in Indianapolis to schedule a time for them to confirm the tailgate switch short and execute the recall service. I was informed by Penske that my specific VIN was not included in the recall. This is not acceptable. Reporting indicates there are a number of other Silverado owners in the same position. Please investigate, as the current state of the recall is most certainly not inclusive of all vehicles that are affected. There should be no hesitation by Chevrolet to broaden the recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

GM has been manufacturing Silverado Pickup trucks with faulty transmission valve bodies for several years. There has been ongoing issues for several years with the defective Valve Body part. I purchase a 2023 for my business. It is presently at a dealership waiting on the part. It is my understanding GM has so many of these issues they can't keep up with the parts. I am told it could be weeks or months to get this part. Online you can see countless others who have waiting 2-3 months for a replacement Valve Body. How can they keep making the trucks with these defective parts. I still have to pay my $1,300 monthly payment while I have no use of my vehicle and they do not pay the full cost of a rental.

I take my truck in for regular service at my local Chevy dealership. When I found out about the recall on my engine back in April I immediately took my truck in. Was advised that they would address the issue. They did a regular maintenance and told me that they just used higher viscosity oil. I will be taking my truck in for the 3rd maintenance tomorrow 6/13/25. My vehicle status still shows that the recall needs to be addressed. I feel that I should park my truck due to the information provided on the recall of losing propulsion at any given time without notice. I also want to note that there is a noise coming from my engine that shouldn’t be there.

My throttle body went out. Horrible shifting and wheel lockup.

Accelerating getting onto the highway, at about 65 mph I heard and felt 2 clunks and I lost propulsion. I made it to the side of the road and the vehicle went completely dead. I tried restarting it and it wouldn’t do a thing.

Valve Body failure on transmission

I was towing my boat, attempting to get on a 4 lane highway via on ramp. Truck refused to shift and went into limp mode as I was attempting to merge. Vehicles behind me on the ramp and coming up behind had to slam on their brakes. Diagnosed as a bad valve body. The issue is very widespread across GM vehicles, GM has a national backorder on the valve body as there are a ton of vehicles waiting for them. GM has not issued a recall at this time.

Valve Body failed - truck currently at dealership The valve body failed as I was pulling out of a gas station - emergency brake immediately engaged and kept re-engaging as I was trying to make it across the street into the parking lot. Truck could not go more than 5 mph and I was stuck and almost hit. Problem has been confirmed by the dealer after it was towed directly there. Unknown if component has been inspected outside of service department. Truck initially would not remote start using key fob, but then made it to gas station fine without any further symptoms. After gas station, car started severely shaking then emergency brake engaged and would not accelerate.

My onstar module stopped working on my 23 chevy silverado. I am planning a vacation and with out onstar I risk being stranded without this service. My WiFi does not work I can not see the speed limit I am unable to contact onstar for help if needed whether that be for directions, or help if I have and emergency. I can not use the handsfree google assistant I took it to my dealer and when I took it I was 400 miles past the warranty. I was not aware of the issue until I tried the handsfree google assistant and if did not work.

This is the third time since the purchase date of July 2023, that my Diesel 1500 Silverado has gone into "Reduced Engine Power" while driving. The first date was August 2024, while traveling down the interstate. The check engine light came on. My maximum speed was reduced to 50mph, and the transmission shifting was very jerky. This was extremely dangerous with the flow of traffic traveling 70+ mph. I returned to the dealer where the vehicle sat on the lot for approximately 60 days awaiting the part (Valve Body) from GM. Components were repaired through warranty. Fast forward to February 2025, "Reduced Engine Power" notification came on again with the code P0747, P700. Returned to dealer, and after a week of sitting on the lot, the technician could not duplicate the code. I requested that a new fuel filter be replaced for piece of mind. Today, 3 mos. later, as I was backing out of my driveway, my truck did not shift/engage into Reverse. I was able to roll into the road & put it in Drive, however it went into "Reduced Engine Power." The vehicle will have to be towed, at my expense, I'm sure, to further diagnose the cause. The truck does not move when shifted into Reverse, and pressure is applied to the pedal. It is extremely concerning knowing a national recall on identical GM components has been reported, and yet I have had identical issues without resolution. Despite the known problems and safety risks, especially with a child in the vehicle during each failure, I’ve been left without consistent or timely support. I am requesting immediate assistance in diagnosing and repairing this vehicle, as well as a formal explanation of why this recurring issue has not triggered a broader response or replacement. At this point, I’m also considering pursuing further action through GM corporate or a consumer protection agency if a permanent resolution is not reached.

While driving at ~30 mph the rear wheels locked up momentarily with no warning and without applying the breaks. The back of the vehicle fish-tailed while the tires slid. Following the incident the check engine light came on and the vehicle went into limp mode and would not go more than about 25 - 30 mph. I immediately took it to the Chevrolet Dealer. The dealer indicated that the codes showed an issue with the transmission control module. It is currently at the dealer to be repaired. The vehicle has 51917 miles and is still under power train warranty. There was no warning or indication something was about to happen prior to the incident. The truck is a 2023 Silverado 1500 with the 2.7 liter Turbo engine with the GM 8 speed transmission.

Fire in firewall dash possibly brake control, battery and electrical fuse box

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 30 MPH, the vehicle stalled. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed that the lifters had failed. Additionally, metal shavings were found inside the engine. The engine was replaced. The manufacturer was informed of the failure by the dealer. The failure mileage was approximately 61,000. The VIN was not available.

Water Found in Rear Interior of Cab, Water Leak at Rear Sliding Window. I noticed water spots on the left and right sides of the headliner. I took it to a dealer (Malloy Chevy winchester Va), and the said it was a TSB put out on this problem and they would file a claim. The truck has 48000 miles and the bumper to bumper company denied the claim. Have the TSB didn't matter to them. Can you assist in any way with this?

Unknown…Randomly started on fire after driving. Police report was filed under 25-000653/Altoona Police (I don’t have a copy)

Connecting rod and/or crankshaft engine component failure, engine damaged, engine light came on as knocking sound started. I have had to replace the motor as vehicle was undriveable. Engine failure can lead to accidents.

In August 2024 my 6.2 Chevrolet Silverado motor blew up. I was driving uphill when all the sudden it made a very loud sound like I had floored it and I had not. The engine revved really, really really high red line then it flashed across my dash to turn off the motor and the vehicle just shut itself off.. It left me stranded in the middle of the road and had to be towed to a Chevrolet dealer. It took them approximately 3 weeks to diagnose it as a catastrophic engine failure. And several more weeks to replace the motor, radiator and coolant lines. There was engine pieces in the radiator. Chevrolet refused to reimburse me my full cost of the rental that I had to get until they approved me a loaner..

Code P1098 associated with reduced engine power, forced speed reduction and overheating while on the freeway, limiting power and capping speed @ 55 MPH. Causing dangerous issues on the highway putting drivers in a dangerous position

Vehicle will not make any sounds. There are no warning sounds, no turn signal sound, no radio sound, absolutely no sound from any speaker in the vehicle. This is about the tenth time it has happened. This lasts until the vehicle is turned off, locked, and left alone for about 10 minutes.

On 4-25-2025 while driving the car shutoff twice losing power on both occasions. The first time I was able to start the truck; however, the second time it happened I lost all power and drifted to a stop. Vehicle info said to put the car in neutral and press the start button. Car failed to start while drifting and when I was able to get the truck to a complete stop, the truck could never start thus requiring it to be towed to the dealership. Truck has a little over 22000 miles. Check engine light came on after the second incident.

I have had an intermittent, aggressive engine knock and rough idle since i bought the truck. I'm assuming it has to do with the collapsing lifter issue from the fuel management system. when I bring it to the dealership (paradise chevrolet ventura) , they tell me that they cannot replicate the issue and that if there is no check engine light on the dash, there is nothing they can do. I am concerned for my families safety and my truck becoming an issue after my warranty runs out. my chief complaint has been documented by the dealership multiple times and I have video of me replicating the issue.

On the freeway transmission downshifted to first, loud bang and skidding to limp mode vehicles behind us skidded off highway and others changed lane causing chaos yelling screaming angry drivers, not a great situation, I had the recall done, it was just a software update that detects a problem and puts it into dangerous limp mode at high speed.

At 383 miles the engine started a ticking noise. Around the same mileage the transmission would also start make hard down shifts, especially into 1st gear. At around 27000 miles transmission would also shutter at light loads and low speeds. Attempted to take it to dealer 2 different times, but they had no loaner cars and needed it for more than a day. At milage 28,251 I drove to the dealership an insisted that it needed to be fixed. They were able to provide loaner car at that time. Engine ticking noise was cylinder number 7 lifter stuck closed. Transmission was unable to be checked due to engine needing repair. The Dealer replace all 8 lifters on drivers side of engine. Upon the fix they test drove for the transmission problem and noticed noise coming from the water pump. Replaced the water pump and was told transmission needed a new valve body. Those parts were on back order for over 3 months. They found a service bulletin to reprogram the transmission so they could release the truck to me instead of hold months for parts. After more than 30 days in shop picked up truck. After driving around for a few hours noticed engine noise again but different. Like a bearing? Dealer had already closed so took it back the next day. Couple days later was informed that the head gasket was installed wrong? REALLY. Went to the dealer's new car manager and asked to be traded out of it and into a new truck. Dealer offered me 10,000 below blue book for trade in! They didn't even want their own product back. Picked up truck couple days later and drove straight to Toyota and traded it in I needed a reliable truck. The dealer's service department was great with the problem. But it's the product that really [XXX] and had the potential to be very dangerous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission shutters and shakes and dealer said it’s normal for the silverados to shake and shutter at highway speeds even though it’s brand new . and then got treated horribly for getting it towed in

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving 45 MPH and depressing the accelerator pedal, the engine seized, and the vehicle lost all power. The contact stated that the vehicle was stuck in the right lane. The vehicle was towed to dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced or rebuilt. The contact stated that the timing chain was replaced on two separate occasions. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 15,121.

On [XXX] around [XXX], I was driving my Silverado down [XXX] near the Cottonwood Mall in Albuquerque, NM. Without warning, the engine died in the center lane of this busy highway. I turned on the emergency flashers, then while trying to call for emergency help on my phone, I stood behind the truck, waving traffic to the side lanes in an effort to prevent being rear ended. After about 10 minutes, luckily, an emergency fire department truck spotted my distress and doubled back, parked behind me and engaged his emergency lights. A good Samaritan stopped an attempted to toe strap me to the shoulder of the road. However, the poor design of this truck didn't allow me to put the transmission in neutral unless the vehicle is running. So, after about an hour, the tow truck driver was able to drag the Silverado on the back of his flatbed. After my truck was at the dealer for a week, they were able to determine that the engine main bearings seized and spun a couple of rod bearings. This is a well maintained vehicle, with the oil changes done on time and documented at the dealership. My Silverado has a 6.2 liter V 8.engine with only 21,532 miles on it.

While driving my 2023 Chevrolet Silverado ZR2 with the 6.2L engine (approx. 22,000 miles) on a busy interstate in another state, the vehicle suddenly lost power and shifted into neutral without warning. I was towing a 5,000-pound camper and had my wife and three children in the truck. We were traveling on a slight incline when the truck unexpectedly disengaged. There were no warning lights, no messages, and no sounds indicating engine failure—just a sudden loss of drive. All displays remained illuminated, but I had no power to the wheels. By the grace of God, I was able to maneuver to the median before the truck and camper came to a complete stop. It was a terrifying and dangerous situation that could have resulted in a major accident given the speed of traffic, the weight of the trailer, and the total lack of warning. The truck was towed to a Chevrolet dealer across the state line. After running diagnostics, I was told the engine had failed and would need to be replaced under warranty. However, I have yet to receive a clear explanation of what exactly failed internally. I was informed that a replacement engine is back-ordered by several months, leaving me without a vehicle and unsure when it will be repaired. The incident has not yet been investigated by the manufacturer, insurance, or law enforcement. This experience was frightening not just because of the mechanical failure, but because it happened with zero indication. I hope others don’t have to go through something like this. I understand thousands of these trucks may never see a failure like this—but for us, it happened suddenly, with our entire family on board, and it nearly ended in disaster.

While traveling in a funeral possession noticed an engine stall with a blast of smoke coming from rear exhaust.

While driving going 40 mph a ‘Brake System Failure’ warning came on and brakes stopped working. Thankfully there were no cars ahead allowing me to continue until the car came to a stop. At that point I engaged the emergency brake and put the car in park and out of gear. I then had the truck towed to a Chevy dealership. I still do not have a response to what the issue is.

At 19k miles the transmission had a shifting problem and went into limp mode forcing a deceleration while on a highway. Had to unhook the battery and hook it back up to clear the code to get to a safe point for towing. Had to do this 3 times. Once at the dealer they could not recreate the problem. One week later it went into limp mode again. Took it to the deal and was informed that the valve body in the transmission would need to be replace. There is a supply shortage on parts and I am now without a truck for who knows how long.

While accelerating from a traffic signal the transmission shifted very hard and caused the vehicle to suddenly lunge forward.

During gear down-shift the rear wheels briefly lock up. This event can be duplicated easily at around 45mph, by slowing due to uphill grade or slowing traffic, then upon normal application of throttle to resume course the transmission shifts to next lowest gear (3 or 4, not sure) there occurs a brief and sudden horrendous jerk as the rear wheels lock & skid. The event lasts less than 1/4 sec, but happens multiple times per day as that speed/load condition is frequent. On occasion, the same can occur in a parking lot ~10mph, but isn't as violent. The first occurrence was at mileage 38,000; the vehicle now has 45,000 miles. This appears to be the same issue as NHTSA Recall No 24V-797, which does not include my vehicle's production year.

The symptoms since the beginning of 2024 have been that when braking between 7 and 10 mph, you feel a bump or a skid, and when you stop, the engine shakes for a moment as if it's going to shut off. This happens with the Auto Stop-Start off. A sudden braking moment can affect the vehicle's performance, making it difficult to control and increasing the risk of accidents, especially when it comes to a pickup truck that may have a trailer with cargo or objects in the bed that can be thrown. The trailer can even leave the road, losing control of the car. In 2024, I took the truck to the place where I bought it, Bomnin Chevrolet Dadeland, for a checkup. I explained all the symptoms to my advisor, just as I do here. I had to take it to wait for a loaner. A few days later, I took it back, and they had it for almost a week. When I picked it up, my advisor told me everything was fine. When I left the dealership, I found the same symptoms, so I went back and told him the car was still doing the same thing, and he told me it was normal. After much insistence, he got in the car with me to show him the problem, and the car did it several times, but according to him, it was normal. Now, in 2025, a week ago I took it to Miami Lakes Auto Mall to get checked out with the same symptoms and explanation. I started investigating why that couldn't possibly be normal car operation. They found they had to replace the torque converter and valve body because they found an excessive amount of metal in the transmission. The valve body is on back order indefinitely at all dealerships, so I had to take the car in that condition. Before taking it, I spoke with the manager and GM to ask them to give me a car until they fixed mine because it wasn't right for me to drive the car like that. But they didn't offer me anything. I took it back to Bomnin Chevrolet Dadeland and they told me they were going to change the transmission and torque converter and conveniently they didn't have to change the valve.

Going 65 on hwy and vehicle looses acceleration

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the engine made an abnormal knocking sound. No warning light was illuminated. The contact stated that the dealer had previously replaced the fan and performed an oil change a week before the failure. The vehicle was taken back to the dealer, who determined that the engine needed to be replaced. The vehicle was not yet repaired and remained at the dealer. The contact related to the failure to NHTSA Action Number: PE25001 (Engine, Engine and Engine Cooling). The manufacturer was not made aware of the failure. The failure mileage was approximately 40,000.

Engine died when I was traveling at highway speed. Not warning lights no check engine lights. Was able to stear to the shoulder but vehicle woulnd't start or go into nuetral. Thankfully on a rural road so was able to get out of danger. Had this happened in a busy environment may not have been so forturnate. Dealer determined that 2 of the connecting rods bent and caused catostrophic engine damage. Since this happened I have read about 100's of other 6.2L gasoline engines having similar issues. This isn't a random occurance and Chevrolet has writted technical memos explaining the issue for thier dealers.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving 75 MPH, the vehicle lost motive power with the check engine warning light illuminated. The vehicle was towed to the dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 25,000.

2023 silverado 1500 ZR2 19000 miles,motor shut off going down the freeway pulling my sxs at 70 miles an hour no warning nothing alarm nothing.my wife and i were scared to death trying to get off the freeway pulling a trailer and not knowing if the truck would make it.people around us beeping there horns with flipping us off,no warning.300$ to get my trailer toed back home.dealership tells me they don't have a loner but would give me a voucher.i have been trying to trade out of the truck after hearing about the truck problems 6.2 is a bad motor i new it was just a matter of time. now i am stuck.the scariest part was the timing could not have been worse coming off the freeway.how do i know even when it is fixed it will not happen again.then we could not get the truck in neutral to toe to dealership so they dragged the $80.000 truck on to the toe truck nice.

I was in stop and go traffic, the truck engine turned off I could not get it to crank. I was stuck in the middle of a busy road for at least an hour until the tow truck driver got there. Since the truck has electric shifting for the transmission, I could not get the truck into neutral to at-least push it to a safe place. I was informed by the dealership that there is no neutral override unless the vehicle is running. The shifting and fuel system “fuel module” failure is a know problem from GM and need to be recalled. If this would have happened on the interstate I don’t think the outcome would be great. The truck is a little over 1 year old and has under 15,000 miles. Very dangerous situation.

I was on Expressway with the cruise set on 72 Miles an hour I heard a loud clunk the engine, of course shut off I go down to the gearshift in the console. It said neutral so close it over to the side of the road got stopped as soon as our momentum stopped and we are completely at a standstill the truck put itself in park. I then tried to restart it and it wouldn’t do anything. I contacted OnStar state in my situation and after multiple conversations with them, I disconnected the phone call and contacted my own towing service because we were 51 miles from our home and they would not tell the people there unless I paid for over half of it. They would only tow it to the nearest dealer. We have been a free customer since 1997. We or a family owned Electrical contacting business. My truck is my office. I’m in 90% of my day. I elected to take it to the dealer where we purchased it, and we purchased a good portion of our vehicles over the years and helps that it would be repaired in a timely manner.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the message “Engine oil too Hot” was displayed. While driving 60-70 MPH, the vehicle lost motive power while driving uphill. The vehicle failed to shift into neutral. The contact went underneath the vehicle and removed the drive shaft. There were no warning lights illuminated. The contact stated that the failure was related to NHTSA Action Number PE25001 (ENGINE, ENGINE, AND ENGINE COOLING). The vehicle was towed to the residence. The vehicle was then towed to the local dealer, where it was diagnosed and determined that the engine needed to be replaced. The contact was informed that parts were on backorder. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The approximate failure mileage was 66,410.

Main bearing failure at 41,000 Miles. No prior warning to issue. Truck is currently at the Chevrolet dealer determining if repair or full engine replacement is needed and parts availability. Check engine light came on when the engine started to make noise.

The tail gate on my 2023 Silverado has started to open on its own both while driving and while stopped as well as attempting to open every 3-5 minutes while the vehicle is off. I contacted Chevrolet after I saw there was open recalls for this exact issue to see if my truck was covered with this recall and to my chagrin it is not. But from what I read, this is the exact issue that other drivers of Silverados between the years of 2020-2024 have been experiencing.

On 3/1/2025, while driving, my vehicle became unresponsive and inoperable . My vehicle stopped at the intersection in a turn lane. The vehicle engine turned off and a check engine light turned on in the dashboard. There were no sounds or indicators prior to the event. All of the controls became inoperable and unresponsive. When I tried to restart the vehicle it would not turn over. I was unable to shift the vehicle out of park. The dash board showed the message “Conditions Not Correct for Shift”. I tried several different corrective actions and referred to the owners manual but I was unable to do anything. The owners manual didn’t specify how to shift the vehicle when it is not running. I had to call a tow truck because we were in the intersection and it presented a concern for safety for ourselves and others the tow truck tried resetting the vehicle, jumping it, and looked for the manual shift override but were unsuccessful. They pulled my truck onto the tow truck and took it to the dealership where I purchased the vehicle. When we arrived at the dealership the tow truck driver consulted with the dealership personnel and were still unable to determine any cause or how to manually shift the vehicle into neutral. My truck has the 6.2L V8 L87 gasoline engine with only 15466 miles. The dealer confirmed engine failure and is in the process of ordering a new engine. There is no known ETA for the engine because it has become a national issue. I have also read multiple encounters of other owners have multiple engines fail and replaced.

I was driving on the highway at about 65 mph, when all of the sudden the truck shut off. There was construction in that part of the highway and there was no shoulder for me to drive off to so I kept driving until the truck completely stopped on the highway. I had to jump off the truck from the passenger side with my wife and toddler and jump the median and stood there in the cold for a few hours while a tow truck came to move the truck out of the highway. We did not fell save staying in the car because there was a lot of traffic and we were afraid to get rear ended. I got the truck towed to my house which cost me $600, the next day i called the dealership to come pick it up. They took it and found the engine was completely damaged. They replaced the engine, but with the same engine model that has the defective engine that NHTSA is currently investigating on these engines. So i no longer feel safe nor can i rely on this truck to run my business.

Valve body went bad... like so many others. No ETA on part from GM. Not a good situation from a business owner that needs a truck to conduct business

Traveling at ~40mph when some knocking could be heard. Pedal manipulation was intermittent. No warnings on the dash. Luckily, I was able to use momentum to get the truck off of the main road and onto a side street. Knocking was heard even louder now - pedal manipulation was now even more intermittent. An error message popped up on the display "Conditions not correct to shift", with no other lights coming on. Truck has now coasted to a stop and the check engine light came on. Cannot put the truck into any other gear. I was lucky enough to not be traveling at a higher rate of speed, but I can see this being a huge safety concern. The truck was towed to a local dealer where i was told that the truck has experienced "Spontaneous Engine Disassembly". However, my service record only states "Check Engine Light On". The attached information is the only thing that I have of the incident and how it's being reported.

While pulling out onto a very busy highway in North Dallas, I had to "step" on it in order to make the turn. Immediatley after making the turn I went to "step" on it and the truck shifted into Neutral with heavy traffic. Luckily I was able to coast to a turning lane safely. Once stopped I was able to place the truck in park. However, after shutting off the truck it was never able to restart. This night was an extremely cold night with subfreezing temperatures. Not being able to start the truck meant no heater and myself and my girlfriend quickly became very cold. After calling OnStar we waiting almost 45 minutes for roadside assistance. However, they were only coming to try and jump start the truck and had to request a second roadside assistance to come and tow the vehicle. The vehicle could not be shifted into Neutral and a flatbed truck had to be used and the truck had to be drug up onto the tow truck. When I first stopped the truck and shifted it into Park, the engine was still running and sounded normal. It just could not be shifted into any gears. However, the GM dealership is telling me the engine seized up and needs to be replaced and could take 4-8 weeks just to locate an engine. Although no one was hurt or injured thankfully, the safety risk when this happened could have been very bad and deadly. Not to mention not being able to have heat during extreme cold temperatures is a safety concern. Had the truck not been able to be parked in a safe area, and not being able to be shifted to Neutral, this also could pose a safety risk.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving approximately 55 MPH, the transmission suddenly malfunctioned causing all four wheels to lock up, causing the vehicle to skid. During the failure, the vehicle abruptly decelerated and veered to the left. After the failure, the check engine warning light remained illuminated, and the vehicle went into "LIMP Mode”. The vehicle was driven to the local dealer who diagnosed and determined that the transmission valve body was faulty and needed to be replaced. The transmission valve body was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 38,000.

February 9 2024 I was driving down the highway at 65 mph and went to switch lanes and realized engine was no longer running. I pulled over and got a tow to the dealership I purchased it from . Truck only had 5000 miles on it and they told me the engine locked up and needed replacement. They performed an engine replacement. It was not completed until April 6, 2024. Two months to get repaired. Today I was driving down the hightway and again engine blew. I heard a spun bearing noise from engine compartment area. Pulled over and engine shut itslef off . Had it towed back in to find out I am on a line of a bunch of 6.2 engines needing replaicing. Very disappointed in Chevy.

On [XXX] I was driving @ 55 MPH. The engine made a loud noise, and completely lost all power and controls. Truck went into natural, all dashboard and screens went black. One I was able to come to a stop the vehicle put itself in park. Truck was towed to Jim Butler in Fenton, MO. I was told by the shop that the 6.2L engine in my truck had a catastrophic failure and needed a new engine. The complete and sudden loss of power and controls put myself and others in danger. No lights or warming of the failure about to happen. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My truck, which has a 6.2 V8 L87 engine, seized up on the highway while on a road trip. The engine suddenly died with no warning or alerts on the dash. The mechanic told me that the oil pan was full of metal and the engine was completely seized. The engine needs to be replaced entirely at just under 40K miles. I have been diligent in taking the truck in for regular service at the dealership, and I had no indication of any problem with the vehicle until it died on the highway while traveling at 65 mph.

coolant control valve The check engine light came on when I started the truck and on-star ran the diagnostic and said it is code P1098. After drive 20 miles a popup on the dash stated, "slow down and drive safe". I was on a 60-mph road driving 55-mph and the truck started slowing itself down. Took it to one dealer and they said the part was on back order and didn't say anything else

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while operating the vehicle, the Auto START/STOP feature malfunctioned, and the vehicle turned off at the stop light while attempting to accelerate. During the failure, the instrument cluster shut off and displayed a black screen. Additionally, on one occasion while reversing, the back over prevention camera screen switched to a black screen, and the vehicle shut off. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not yet notified of the failure. The failure mileage was 18,000.

The vehicle check engine light came on and a message displayed "Reduced acceleration. Drive with care." My acceleration was very slow but that was the only symptom, although I was driving speeds under 55 MPH. I took the vehicle to GM with CEL Code P078 and they replaced the high pressure fuel rail. Two days later the CEL came on again with code P228B. I was driving on the highway when the message came on and I could not accelerate the vehicle. If I tried to push the gas pedal more than halfway, I would lose both speed and power. I could not maintain my highway speed very well and could only accelerate if I slightly pressed the gas pedal. This is a serious safety concern because it may cause an accident if I am not able to maintain speed on the freeway. Additionally, this is of concern because I rely on my vehicle to pull a camper, and with this condition, I would be a "sitting duck" with my family in the vehicle. GM continues to diagnosis the issue but has failed to respond in a timeline and satisfactory manner.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving 70 MPH during inclement weather, the transmission unexpectedly downshifted hard, jerking the vehicle, and while slowing down the contact observed a squeaking sound coming from the front of the vehicle. The contact stated that while depressing the accelerator pedal the vehicle failed to accelerate as intended. The check engine warning light was illuminated. The vehicle was steered off the highway and turned off. The vehicle was not able to be restarted. The vehicle was towed to a dealer where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 34,000.

I have a 2023 Chevrolet Silverado 1500 and the OnStar is completely out the dealership say they have no idea when a module will be ready. I have talked to and seen several forums on this. Everyone states it’s a huge problem and now they want to charge up to $1000 to replace the module it is not covered by warranty. I cannot even use my navigation my security all the things that OnStar provides due to this module problem they have it seems to be getting bigger and more widespread. We should not have to pay for something that has nothing to do with the warranty of the truck. It is a malfunction with OnStar and Chevrolet

The starter did not disengage and caused engine failure. Loud screeching occurred while driving. Pull off road once noise was heard and truck needed to be hauled back to dealership.

The digital gauge cluster where speedometer and other essential gauges for the vehicle failed. It is available upon request. My safety is at risk as I’m unable to determine speed, monitor ABS, or monitor other essential features that the guage cluster provides. It also periodically blinks on startling me and putting my life and others in danger. The dealership has confirmed this problem and saodnit is a know issue with this year model but my particular VIN number wasn't recalled. The dealership has inspected the part. There were no symptoms or messages prior to the part failing.

Transmission Control Valve Body. known issue on the 10spd transmission. GM will not do a recall. my truck was in the shop for 5 weeks in March 2024. Coolant Control Valve. known issue on these vehicles. GM will not do a recall. my truck is currently on its 4th week in the shop. and they are telling me it's 2-6 months out for the part. GM is continuing to manufacture new vehicles while those who already own vehicles are stuck waiting on a backordered part.

Vehicle started making an odd noise and was immediately taken to the dealer. Engine light did come on after the noise started. Dealer confirmed that there was an issue with the camshaft/lifters and that they have had to perform this repairs to 8 other trucks with the same 6.2L engine. (Original repair bill is attached). Dealer performs the repairs, takes the truck for a test drive and within a few miles the engine completely seizes up stranding the truck in the middle of the road. They believe it was a separate issue that caused the engine to seize up and now after 12k of repairs I will also need to purchase a completely new engine. Currently waiting on the price and availability of a new engine but was told I may have to wait a long time since this is such a common issue there aren’t many available. Would be more than happy to share additional Info as it becomes available.

I was driving to work from Livingston to Bozeman and the roads were bad so I was only going about 60 maybe 65 which was reasonable for the conditions this day, and out of nowhere my truck locked up and I slid it directly into the center median.

Engine failure while driving without warning (lights)which caused catastrophic damage to Engine and needed to be replaced

Catastrophic engine failure , heard a ticking called dealer where i purchased truck new , was told not to drive it . No warning..

The motor of our vehicle failed while driving on the interstate. The vehicle is at a dealership for repairs and should be available for inspection. With little to no warning our truck quickly went from 70 MPH to completely shut down. We had to go from the left lane on the interstate to the shoulder. In the process we were very close to a collision. We were also hauling our camper (2023 Forest River R-Pod 153, which has a dry weight of 3,421 lbs and we had no water in our fresh/grey/or black tanks). When we merged into the right lane our truck was going so slowly on the interstate that we were almost hit and honked at before we could get to the shoulder safely. The problem was confirmed by the dealership that is working on it. The motor spun 4 rod bearings and it was a total motor failure. The vehicle was/is still under warranty. The manufacturer, I would assume, has inspected it as we are receiving a full motor replacement. That motor has been and continues to be on back order with no ETA for 2 months now. There were no warnings in how the truck was running. There were no warnings on the dash, warning lights, or any indication that our truck was going to break down.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the message that the vehicle was in neutral was displayed. The contact pulled over to the side of the road, turned off, and restarted the vehicle however, the gear shifter failed to respond as needed. The vehicle was towed by AAA to the dealer and the dealer was contacted. The vehicle was diagnosed, and the contact was informed that the engine, the radiator, and the oil cooling lines needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 45,000.

We were driving our truck with our family on vacation. We were going slowly entering the parking lot to our hotel when a sudden loud grinding noise caused our truck to shudder and shake. We stopped and got out and didn’t see that we ran over anything. We started to proceed and the sound was the same. We parked in a stall and left the vehicle overnight. No check engine lights were on. No warnings at all. It was Memorial Day weekend 2023. There were no dealerships open where we were vacationing, 3 hours from home. Very inconvenient. Later when the dealer looked at it, the thrust bearing was bad and the engine was shot. Needed a full replacement at 10,600 miles.

Transmission seal failure caused fluid to leak, transfer case had metal present and had to be flushed, multiple electrical issues where there was no sound and buttons on back left of steering wheel wouldn't function, vehicle put itself in neutral when passing and gave a conditions not favorable for shift change when I tried to put it in park. Eventually put itself in park and I was able to get home. Dash went black, ticking sounds quickly escalated to the motor blowing thankfully close to a dealership on 1/2/2025. Still awaiting a timeframe or information on what will happen. Unable to attach video

[XXX] I was heading home from work, driving on [XXX] near [XXX] 2023 Chevy Silverado 1500 ZR2 broke down. I lost all power in my vehicle, besides brakes and steering, and had to coast into the breakdown lane. After restarting my truck, I was able to drive another mile on the highway until I lost all power again on the off-ramp. My truck was broke down, halfway in the road, and I could not start it back up to try and move it. I remained there in the subfreezing temperatures with no heat in my truck for over 1.5 hours waiting for a tow through OnStar that never showed. A state trooper eventually pulled behind me because I was blocking traffic and then proceeded to call a different tow company which arrived about 15 minutes after he called. Since that day, my truck has been at Colonial Chevrolet in New london CT waiting for a “nationally backordered” 6.2L engine. 53 days without my truck that I use for me and my business partner’s construction company, and no ETA for when the new engine will be arriving.

I was pulling into my neighborhood when my engine started rapidly thumping the higher the rpm’s got. I was able to get it to my local Chevrolet dealership. Flaherty Chevrolet in Brandenburg, Ky. They told me it had catastrophic engine failure. I’m currently waiting for a new engine replacement. They’re trying to find a new one, but are having no luck.

While attempting to pull out into traffic at a T intersection, the vehicle would not accelerate as I got into roadway and gave me a "Reduced Acceleration" notice. I was almost hit by a vehicle that was coming towards me. This has happened 3 times now. I have not taken it the dealer yet.

I was driving on the interstate when the power steering failed. I was on a straightaway so I was able to force the vehicle to the side of road and have it towed. If I was in a corner, I would have crashed. It was repaired at Chevrolet Dealership.

Moter blew with 19,000 miles on a leased vehicle. Blew a rod out of the block and there was no warning light or notice at all. Almost got rear-ended. Took 3 months to replace moter. New motor knocks and ticks...... I also told them the 10 speed transmission slips between seventh and eighth gear they said there's nothing wrong truck still slips between seventh and eighth gear to this day.

While driving down the highway, a message popped up stating “not suitable to shift” and I lost all acceleration and could only coast. Luckily was able to coast over to the shoulder, where attempts were made to shut down and restart vehicle. Second message came up stating reducing features to save battery. Was unable to restart and a tow was requested. Dealership reported it was unknown why or what caused it but engine was locked up. Engine only had 19k on it with just me as the owner.when purchased brand new 17 months prior.

When all the brake settings are set to factory and I back out of my vehicle onto the main road in front of my driveway the vehicle will occasionally detect something and lock the vehicle in park with emergency brake engaged. I then have to put the vehicle in drive all this while oncoming traffic may or may not be oncoming. The brake engagement happens if the corn in the field is blowing the right way or shadows from the tress. I had this into the dealer and also contacted the manufacture. They both told me to turn off all the safety features so this wouldn't happen or do not back out of my driveway.

I was going down the interstate and my car engine turned off and almost made me crashed into another car. Chevy dealership took it and after a month they said the engine is locked up so it needs a new engine now.

My trucks engine failed when I was driving on the highway with my family in the vehicle. The truck lost power and struggled to get off on the side of the road. Truck has been at the dealership since 25 Nov 2024 with still no diagnostics. GM is claiming they will not replace due to lift on the truck which has nothing to do with all these engine failures. Last contact from dealership was 27 Dec 2024.

Motor seized while driving on freeway at 65 Mph. Coasted to the media on the freeway in the middle of a dividing highway. The highway patrol stopped and then left feeling unsafe. Dealer would not tear down without a $3000 release from me for labor, if not covered under warranty. This is now a federal investigation with this motor and over 86k complaints. I would also like to add, this happened to a new truck my son bought in 2021 Silverado trail boss so GM new about these motors and are still selling them!!!

Faulty coolant control valve causing reduced engine power at highway speeds and reduced acceleration caused unsafe operation on highway. Was unable to safely maneuver to right lane on highway to allow faster traveling traffic to pass. Fortunately was only about 5 miles from home and was able to operate the vehicle in "limp" mode after traffic cleared. There was no warning just during operation check engine light and reduced engine power displayed on the drivers information center. The vehicle is available for inspection with the defective part because GM can't source a replacement despite occurring nearly eight weeks ago. GM has authorized the warranty repair and is currently at a Chevrolet franchise dealership awaiting repair parts. The manufacture is aware of the issue and has accepted a manufacture engine part is the cause of the issue.

Engine seized at 330 miles. I’ve recently seen the investigation into crank bearing failure on the L87. We upfit new vehicles. This was a test truck. We pulled oil from another identical chassis with 10 miles on it and sent it in for testing to a 3rd party. At 100C/212F the viscosity was under 7 and it should be 20. It is our belief that GM has faulty bulk oil they’re putting in new vehicles.

There were no symptoms prior to the engine failure. On January 14th, 2025 while driving 58 miles per hour heard a sound that sounded like a slap on the back window. After the slap sound I noticed the engine was not running as normal. There was also a sound coming from the engine like metal rattling around. A few minutes later the check engine light appeared in the instrument panel. Had the vehicle towed to the nearest GM dealership and was informed that the thrust bearing went out which may have caused damage to the crankshaft.

The contact owns a 2023 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 24V674000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. Parts distribution disconnect.

I was driving and received a check engine light with “Service ESC” and traction control was disabled. Performed diagnostics and found P0300, P0304 and P0204 all relating to cylinder 4 misfire and injector issues on cylinder 4. Truck has just over 47,000 miles and may be related to the lifter issues that plague this engine design.

2023 Silverado with 10 speed transmission. 20K miles. On 11/30 received "Reduced Power" message, quickly followed by "Service Transmission Now Unable to Shift Soon", which was quickly followed by "Service Transmission". CEL came on. Transmission was shifting erratically, and not shifting into higher gears. Clearly a safety concern. Dropped it off at a local dealer on 12/1. Dealer service advisor contacted me 12/12, saying they were finally able to diagnose the problem and the transmission needs a new valve body. However, the valve body is on back order and there is no estimated time for when it will be available. The internet is awash with stories of the same issue with GM's 10 speed transmission in the light duty pick up trucks, leaving owners waiting for weeks, even months before their vehicle is repaired.

My tailgate randomly opened while the vehicle was parked this fall on three separate occasions. I see there was a recall (N232426400) but it only included the Canadian equipment. Can we be certain the Canadian equipment wasn't used in my vehicle? If the Canadian equipment was faulty it's not a stretch to think the American or other equipment could be too.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle lost motive power and decelerated to 20 MPH. The check engine warning light illuminated with the messages, “Reduced Acceleration – Drive with Care/Service Emission Systems” and “See Owner’s Manual” displayed. The contact drove the vehicle to the residence and the vehicle was then towed to the to a local dealer to be diagnosed. The contact was informed that the wiring harness was faulty and needed to be replaced. The vehicle was not repaired. The contact linked the failure to Customer Satisfaction Program: N222391510. The manufacturer was notified of the failure. The approximate failure mileage was 47,295.

Vehicle was re-started after running into a store, vehicle made loud growling noise from engine compartment and Service Engine Soon light came on. Took truck to dealer for diagnosis and repairs. was called and informed That the Coolant control valve was defective and that NO parts were available at this time, and that the expected part arrival dat was the third week of January. When asked if the truck was drivable was told that it wasn't recommended due to engine overheating concern and vehicle going into LIMP mode and leaving me in an unsafe situation if traveling on a highway or at freeway speeds.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving approximately 70 MPH and hauling a small box trailer, the vehicle slid several times. There was no warning light illuminated. The contact pulled over to the side of the road temporarily and resumed driving; however, the failure recurred several times. The contact pulled over to the side of the road. The manufacturer was contacted and informed the contact that towing assistance could be provided for the vehicle but not for the box trailer. The contact decided to continue driving the vehicle to the residence while the manufacturer remained on the phone with the contact. The contact stated that upon test driving the vehicle the following day, the vehicle operated as needed. The vehicle was taken to the dealer, where it was inspected, and the dealer removed the valve body of the transmission per the manufacturers' instructions. The dealer then informed the contact that metal shavings were found in the transmission pan. The dealer replaced the transmission. The contact stated while driving at various speeds, the rear end of the vehicle continued to make an abnormal humming sound. The vehicle was taken back to the dealer, where it was test-driven, and the dealer determined that the rear end of the vehicle needed to be rebuilt. The vehicle was repaired. Additionally, the contact stated that while his wife was driving 40 MPH on a wet road, the vehicle inadvertently slid off the road and drove on the grassy area covered with snow. The contact's wife steered the vehicle and missed a ditch; however, the rear passenger's side of the vehicle and the rear passenger's side tire struck a pole. The air bags did not deploy. The driver did not sustain any injury. The driver exited and inspected the vehicle. The driver was able to continue driving. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 23,000.

Vehicle goes into reduced power mode and prevents safe acceleration in traffic and is a major safety concern. The Coolant Control Valve is the issue which has been a problem in the Silverado for a few years. This part is also on national backorder.

The sound on the Infotainment system, which controls the radio, apple car play and phone calls cuts out randomly and will not turn back on until the truck is turned off for 10 minutes or you pull over and park and do a reset in safe mode. This is a hazard as you can not make emergency call while driving or if you are on an emergency call while driving you are forced to go from hands free to holding your cell phone while driving. I reach out to Chevrolet several and brought the truck to 2 different dealerships and it is still not fixed.

While driving the Vehicle - the left turn signal stopped working. When dropping off at the dealership was informed it is a software issue. The issue went away for a couple of months and then the exact thing happened when using now the right turn signal. This provides no way of letting other people know who are headed towards my vehicle that i am turning lanes. The last incident was verified by the dealership. The headlight is not serviceable. No warnings occurred until after a few blinks where the front signals wouldn't work then indicated that the light was malfunctioning.

randomly several times a day the google assistant comes on unexpectedly and starts to talk, via the infotainment system. She says "I cannot do that but in the meantime you can......"

After repeated software upgrades, the infotainment system continues to drop bluetooth calls causing the driver to pick up the phone manually. System will drop the connection several times during a 5 min call. This causes the driver to get distracted. Radio system has been updated twice under warranty. Problem is still not resolved.

All lights including dash lights turned off while driving at night on the interstate at 82mph. Not sure if my knees hit the light switch or not but not sure why even dash lights went out. Brought vehicle to local Chevy garage, there was no code and they couldn’t duplicate the incident.

Three weeks ago, I exited my running truck and saw that the left front driving light wasn't working. Turned the turn signal on and it would not function either. At first the rear light was blinking normally. Then after about a minute it began to flash rapidly and the display showed, check left front turn signal. Shut it off and unit worked after restart. Two weeks later, did the same thing. This time it did not reset until the next day. It seems to malfunction when the headlights are activated, and I noticed there is a unit mounted on the back of the headlight assembly that appears to control it and the headlights, as it is one unit. I recorded it on video, and when I took it to the dealer, they were able to confirm the issue. They are going to replace that assembly. After some research, I am discovering that this is beginning to look like a common issue as others that own 2022 model years and up report the same thing. My vehicle has only 12,600 miles on it, and I have found people with 2024 GMC trucks also experiencing it. This is concerning as it is a safety issue with nonfunctioning turn signals or running lights. As I stated before, the first time it happened there was no warning that the driving light wasn't working nor was there a warning the first time it happened that the front turn signal wasn't flashing for over one minute. Most times your signal isn't on for that period of time. Mine is warranted but some people said that without proof; the dealer can't duplicate the issue, so they aren't replacing it. Out of warranty the lighting unit costs about 1,500.00 and it isn't something an average individual can replace. GM also charges a 200.00 core charge on these. The service manager called it a restricted item. I would appreciate your looking into this to see how widespread this might be. I'm assuming it has something to do with the headlights being on and the heat generated by them causing the failure, but that is just a guess. It is a safety issue though

Within weeks of buying the truck the Auto STOP/START quit working. I never gave it much thought until after a service visit and it was again working. I asked the dealer and they said the battery voltage dropped below a set level, turning off the Auto STOP/START. It quit again days later and has never worked again. There is no apparent reset. My battery voltage is normal, I have a REDTIGER F7N 4K Dual Dash Cam running 24/7 but it is drawing 4.5 to 5 watts; the car is rarely left parked for more than a day. I was initially bothered that there was no On/Off for the Auto STOP/START but I am even more frustrated that it is no longer working and no apparent reset short of taking the truck to the dealer for service.

I have found between the last two oil changes, I have had to add 1-1/2 to 2 quarts of oil. I first thought that maybe the oil was not refilled fully but after the second time I asked the dealer about this and they said that the engine may need up to 2 quarts of oil added between oil changes. SERIOUSLY?! I cannot believe this is normal for a new truck with less than 30,000 miles. There is no leaks in my driveway, no obvious exhaust smoke.

As also reported by another owner in NHTSA ID Number: 11602844, I have found several times that while driving on I-80 at or near speed limit with adaptive cruise control on and no traffic, no weather, dry pavement, that the truck suddenly applied the brakes hard. There was nothing on or upcoming in the road, the sides of the road were desert and near the road was clear. Over the course of the past year this has happened probably half a dozen times.

Headlights and wipers stopped simultaneously for 1 second

On approximately 6 occasions over the past 12 months, either the right front turn lamp or left front turn lamp failed. Most recently this occurred on 8/27/24. When this happens, the entire front head lamp does not work. A warning on the dash shows as "Check Left/Right Front Turn Lamp" and the audible turn signal click is faster than normal. Turning the truck off for approximately 15 minutes fixes the issue until it returns again at random. Having functioning head lamps and turn signals is critical to safely operating a vehicle.

Truck started hesitating for no known reason. No check engine light, nothing. Shortly thereafter, truck stopped shifting after I pulled out into a very busy intersection. Would not move briefly. I quickly put it into park, then neutral, then drive again, and was able to limp out of the intersection, just missing oncoming vehicles. I was then able to barely limp to dealership. Check engine light finally came on just before I got there. They say defective transmission cooler seal and lines. I have no idea. Truck in shop for 5 weeks and no idea of when it will return. According to various Chevy/GMC forums, it's happening to others. Some have had entire transmission replaced in a car less than a year old. Not being able to exit an intersection is a problem.

On June 16, 2024, my vehicle stalled on a 70 mph interstate. I was able to get to the side and attempt to restart. After ten minutes, the vehicle restarted and I received a message of "Low Battery". I drove it immediately to the dealership and advised service. The next day I called the dealership for a status update and was advised the engine seized. The vehicle had 3,212 miles on it at the time. The dealership ultimately received permission to replace the engine which took about three and a half weeks. The vehicle is simply not the same and has several issues since. One was a No Start and No Power.

The way the hood on my truck was designed should be modified. If the sun hits my hood it about blinds me, the glare is very bright. One time I couldn't see the road for a minute or two. The sun visor does not help or solve the problem

at about 20k miles the valve body went out. When coming off the brake and pressing the gas the engine was jerking. The engine light came on and then started to downshift. The truck was towed to the dealer and they said a few days later it was the valve body. All the miles of the truck were highway miles and no towing was ever done on this truck.

Automatic Transmission Valve Body Failure. It is available for inspection. Safety issue: Lost high gears and low gears while towing a camper trailer, speed limited. Dealer confirmed problem and ordered parts. No advanced notice of the problem. Transmission experienced a hard shift and check engine light and warning message appeared. Dealer reports new part GM Part #24047995 is unavailable nationwide due to so many other customers with same problem. No timeframe given of when a part could be available.

This weekend while traveling on I95N I got into a wreck with automatic cruise control on. I had been in stop and go traffic for about 20 minutes and was following behind a Gatormade hauling trailer for well over a mile with no issues. Suddenly, from a dead stop, the truck attempted to accelerate to its preset speed of 50 mph. I was only one car length away from the trailer and wasn't covering the break. By the time I got my foot on the break, I slammed in the back of the trailer. At no point did the emergency brake warning or any alerts pop up.

On our road trip back home driving on the highway using the adaptive cruise control set to the speed limit and it’s night. Clear night and no traffic or rain. The truck applied brakes hard and dropped about 12 miles per hour. Another hour later same thing happened. I was fortunate to avoid the car behind me. There was nothing on the road ahead of me.

Forward collision system will light up and state it is not functioning. Will reset once truck is turned off for a bit. Stereo audio will intermittently cut out and stereo needs to be reset to hear audio again. Apple CarPlay will intermittently not connect

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at 15 MPH, the brake pedal depressed to the floorboard and failed to stop as needed. No warning lights appeared on the instrument panel and the forward collision avoidance feature failed to operate as needed. Due to the failure, the contact crashed into another vehicle. The air bags did not deploy upon impact. Neither the contact nor the passenger sought immediate medical attention; however, the other driver did state they would be seeking an X-ray. A police report was filed. Due to the accident, the vehicle was towed to an independent mechanic where it remained in their possession. The dealer was notified of the failure but offered no assistance. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 11,000.

Took truck to dealer for oil change 05/28/2024. After service was completed truck was returned with Forward Collision Avoidance warning light activated. Spoke with service advisor who had no idea how to reset sensor. They cleaned windshield at camera location and still not reset. Took vehicle home and discovered cruise control was also disabled. Had to make another service appointment to have Forward Collision Avoidance and cruise control repaired.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the ductwork above the brake pedal disabled the contact from rapidly depressing the brake pedal. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 2,000.

While driving approximately 20MPH and entering a left turn lane, I activated the left turn signals and discovered the driver side front turn signal was inoperative. A cluster message appeared indicating the left front turn signal was inoperative along with hearing the audible double speed "tick tock" indicating a bulb failure. When I arrived home, I also discovered the daytime running lamp (DRL) on the driver side, which shares the same portion of the lamp as the turn indicator, was also inoperative. On the next drive cycle the fault cleared itself. A non-functioning turn signal increases the risk of a vehicle crash. This is also a non-compliance with FMVSS 108, Lamps, reflective devices, and associated equipment. VOQ's 11584694, 11582809, 11577734, 11566682, 11561217, 11555917, 11548335, and 11528583 describe a similar failure and are happening early in the vehicle's life.

MY Vehicle (2023 Chevrolet Silverado) has been in the shop over 9 times due to issues with the radio. I bought Truck on June 2 and since then have had truck in several times due to a radio issue. Each time i have taken truck in i have been told it's a "Software Update" should be good now. Spoke with GM Customer care and their exact words were shut the radio off drive without it. The radio volume with go full blast while driving even when the radio is turned down low. When this happens, it scares you some wheel jerking. I could see someone getting hurt while this is happening, upon looking at a few different forums i am a part of this is a concern and affects a lot of drivers. The fact GM customer care simply states just shut the radio off is a real concern, We as consumers pay a lot of money for these vehicles this in my opinion is not the correct response. They don't have a fix for this yet is also what the woman from customer care had to say. this truck is over a year old. how is this possible? GM is aware of this issue but has done nothing but continue to put people's lives in danger. I don't think telling their buyers to turn off the radio and drive without it is what should be getting said.

No idea where the problem lies due to inconsistent trouble codes, the truck will randomly start jerking and sometimes kill itself after throttle won’t respond no matter the speed. Every time I’ve had somebody drive it, it does not act up for them. I’ve had several parts replaced with the same problem coming back 50+ miles later. When it gets ready to shut down it throws the check engine light, service esc, collision light, and traction light, then says speed reduced or speed will be reduced in 175 miles. I have video evidence of all of this.

Radio cuts out, no sound. Can't even use hands free calling because the sound doesn't work. Driver will try to get sound back while driving, taking eyes of the road to fiddle with radio. No recalls at the moment for this issue. Several blogs online that people are experiencing this issue. Has not been inspected as the issue is intermediate, cannot reproduce at a certain time. Could happen once a week or several days in a week, random. There were no warnings before the radio cuts out.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while using the left or right turn signals, the message "Check Left Front Turn Lamp" or "Check Right Front Turn Lamp" was displayed. During the failure the exterior turn signal had become inoperable. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The manufacturer was notified of the failure. The failure mileage was 4,000.

Vehicle caught fire and burned up while idling at my babysitters

Multiple random electrical issues, including, but not limited to: 1) "Service ESC" warning activates causing the truck to have greatly reduced speed and power. Extremely dangerous at expressway speeds in heavy traffic. 2) Electrical system & engine completely shuts down with no warning. Extremely dangerous for obvious reasons. Temporarily remedied by disconnecting/reconnecting battery, thus resetting the system. Problems have been confirmed by the dealer, Bomnin Chevrolet- Dadeland. Supposedly vehicle has been inspected by a GM "TAC" technician. Vehicle has been and is currently in the possession of the dealer off & on approaching 2 months with no resolution.

The contact's husband owns a 2023 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at approximately 60 MPH, and shifting gear, the vehicle lost motive power for 15-20 seconds. The Forward Collision Avoidance warning light was illuminated. On another occasion, while her husband was driving at an undisclosed speed, the driver assist function was activated, an error message was displayed, and the vehicle failed to operate as intended. The vehicle was taken to a dealer and the contact was informed that the transmission fluid needed to be flushed, and the TCM module needed to be updated. The vehicle was repaired, but the failure persisted. The manufacturer was notified of the failure. The failure mileage was 42,000.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the vehicle was designed with the Auto START/STOP feature. The contact stated that while at a complete stop, the engine shut off and failed to restart upon releasing the brake pedal to drive the vehicle. The contact stated that the failure had been recurring. The vehicle was taken to the dealer, where it was diagnosed that the Auto START/STOP sensor had failed and needed to be replaced. The vehicle was repaired. Additionally, the dealer advised the contact to disengage the feature when driving. The contact followed the dealer's recommendation. The contact stated that on one occasion after forgetting to disengage the feature before driving, while at a complete stop, the engine shut off and hesitated to restart. The message "Brake System Failure" was displayed, and the brakes became inoperable. The contact pumped the brake pedal, but the vehicle failed to respond. The contact allowed the vehicle to roll from a complete stop and pull into a gas station. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was unknown.

At approximately 9k mi the engine performance (2.7L MAX Turbo) started to become intermittent. I always record the fuel milage, and always drive the same way, to/from work. NOTE: Displayed mpg calculates within 1% of actual. We can assume the driving habits are identical each time. While driving on the same tank of fuel for a week at a time: one day heading to work the indicated mpg might be 17 mpg. Driving home, about 10 minutes into the drive, it might increase 25 mpg. The following day it could be the same 17/25 mpg or it might be 25/17. The weather is somewhat dependent, whereas around =<43F the 17 mpg is almost a guarantee. While the indicated lower mpg is displayed, a direct lack of engine power is noticeable. The accelerator is dangerously non-responsive, all the while of pressing the pedal >3/4 to the floor. There is also no downshifting from the transmission whatsoever. To make the engine respond to change, the accelerator must be fully pressed to the floor, forcing the transmission into a lower gear and causing the engine to 'wake up'. When the mpg is above 20 or 21 mpg, (and temperatures >50F) the engine performs normally, where gradual accelerations to the pedal increase the engine speeds and down shift as expected. I have contacted GM through the 'MyCheverlot' app a couple of times, and have taken the truck to the dealer twice for this. Both times from the dealer it was stated that since the engine light was not on and no codes were stored, there was nothing that could be done. The dealer installed a software update and sent me on my way. Lastly, the 4WD is now making a grinding/rubbing noise, since the software update and overcomes the engine power while making turns from a stopped position. If no acceleration is applied, the truck will come to a rapid complete stop if rolling <10 mph. Truck is a LEMON!!

Lost all sound in the truck. No warning sounds , no turn signal sounds, no radio, no navigation sounds. I missed a notification of a wreck on the road in front of me that would have been audible if the trucks sound systems were working.

Truck is equipped with a power up/down tailgate. I was driving on a rainy day and stopped for gas. Upon putting the vehicle in Park and shutting off the engine, the driver information center alerted with a dinging sound several times. Upon returning and starting the engine the information center alerted that the tailgate was open. I got out and checked and the tailgate was open. I closed the tailgate by manually lifting it. I believe this is a safety issue and the switching mechanism or sensor needs to be repaired or replaced.

On first start up when put truck in drive and give gas when it shifts from 1st gear to 2nd gear there is a big hesitation when trying to shift and rpm’s revs up then it goes into 2nd gear. This has been verified by the dealers service advisor. The service advisor says they have no service bulletin on this problem so they have no solution for it at this time. This has been happening since August 3 2023 off and on until today. I have many recording of this happening. The service adviser has listened to several of them.

On [XXX], while driving 70 mph on [XXX] towards Weatherford, Texas. There was an unoccupied vehicle parked on the shoulder of the highway that was at least 15 feet from my lane. The automatic braking system slammed on the brakes unexpectedly. On [XXX] while driving 65 mph on Highway [XXX] from Cleburne Texas to Fort Worth Texas, a Texas Department of Public Safety (Highway Patrol) was parked on the shoulder of the North bound lane. Right as I was about to drive past the State Trooper, the automatic braking system slammed on the brakes unexpectedly again. I was then pulled over by the State Trooper, I explained what had happened, and he let me leave without writing a ticket.

AFTER USING CRUISE CONTROL THEN BRAKING -CRUISE CONTROL DISENGAGES AS NORMAL. THEN PROCEEDING TO PARK AT LOW SPEED AND TURNING THE STEERING WHEEL TO PARK-IT SEEMS LIKE CRUISE CONTROL ENGAGES AND CAR ACCELERATES. IT ONLY HAPPEN A FEW TIMES -5 SO FAR- ONLY HAS ABOUT 9000 MILES. APPLYING BRAKE DISENGAGES THE PROBLEM. NO INCIDENTS OCCURRED, BUT COULD CAUSE SERIOUS PROBLEM.

When accelerating, the transmission is having issues changing gears. When the truck is trying to change gears, there is a tugging type of feeling. We have not taken the vehicle to the dealer, but we have seen that other similar vehicles are having the same issue. No warning lamps or messages appear.

While stopped at an intersection my truck lost all electrical power. a couple of seconds later the dash lights came on saying that the vehicle did not have any brakes or brake assist. Then while the vehicle was still in drive it started. due to the brakes not working the vehicle jerked forward. I put the car in neutral. The light turned green and I was able to get out of intersection and then went to the side of the road. While driving this short distance the vehicle displayed that because the brakes were not working it would not go over 62 MPH. Once I was able to stop I shut vehicle off. I waited a short time and restarted the vehicle. This appeared to fix the braking problem but the check engine light stayed on. Drove home with no further issues and called for service which will be 2/19/24. Mostly my concern is that the vehicle restarted while in drive with the vehicle having no brakes.

2023 Chevrolet Silverado ZR2 purchased 7/10/2023 with a 6.2L gasoline engine - Lifter and engine bearing failure leading to complete engine failure at 5920 miles on [XXX]. Dealership has been in possession of the vehicle since [XXX]. Engine failed, leaving me stranded at an intersection blocking traffic in single digit temperatures. Due to the electronic gear shift, there was no way to put the vehicle in neutral to move it from the intersection. The tow truck driver was forced to drag the vehicle onto flatbed tow truck, possibly damaging other components in the process. This appears to be a common issue that is known by General Motors without remedy. Appears to be related to the Dynamic Fuel Management system and spring-loaded lifters that fail. The vehicle has been inspected by Chevrolet Dealer, who determined it needs a full engine replacement. There were no warning lamps or messages leading up to the failure. Vehicle drove normal for over 100 miles on the highway. Upon exiting the highway, the auto start stop feature turned the engine off at a stop light. Upon letting off the brake, the engine struggled to start back up and check engine light came on. Pulled over immediately, and upon stopping at the stop sign the engine seized and would not restart. This led to me blocking an intersection for over an hour in single digit temperatures waiting for the police and a tow truck.

The transmission has a shudder during gear change and at certain speeds. First noted to dealer at 7,500 miles and they could not duplicate. At 15,000 it is worse, they confirmed the issue but had no fix. New truck, they want me to just accept the problem for the moment and keep driving it. Not happy, distracting, wonder about damage being caused, and long-term impact. Will it quit on trip, middle of the night, etc.?

I purchased the vehicle on [XXX] at 124 miles it died at parking lot and would not start, called dealer i bought from they were no help. I had vehicle towed to local chevy dealer Dyer and they pulled VIN and said it was in open recall something about fuel injection flow, they said it should have never left the lot or been sold so now i'm up the creek no truck and not sure where to go with problem. Dyer says it is open ticket and they should have known this. The sales manager at Alanjay said he shows no recall on the truck. The print out from Dyer shows recall release on 01/10/2-24 and i bought on 01/17/2024 there saying they Alanjay should have caught the recall.

The truck will intermittently stop making any and all sounds. No turn signal sound, no seat belt unbuckled alert, no radio sound. It remains that way until the truck is powered off and restarted. This includes all warning chimes and infotainment sound.

Several things have happened multiple times now. While driving on an interstate the truck suddenly lost power then from 70 mph dropped almost immediately to 30-35 which almost caused the vehicles behind me to slam into me. Another time the auto stop came on waiting at a red light then when the light turned green the truck threw all alerts on the dash and died. Now I was parking and the esc control light came on then the trailer braking light and now the vehicle lost all power all together. I am not able to start it or even lock it.

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission "shifter" has a Parking switch on top of the shifter. Pushing the shifter full forward results in the transmission being in REVERSE. Vehicles have had full forward result in PARK for as long as the automatic transmission has been around, creating a dangerous conflict between muscle memory and function. There have been two close-calls where my mind has considered it to be in PARK and when letting off the brake, the truck began moving in reverse. Luckily, I would have only hit a parked car but if there was a person behind me? Things could turn bad, quickly.

My tailgate has opened without activation 3 times while on roadways sending cargo to the road. This fortunately has not causes an accident (that I know of) but the potential obviously does exist as a vehicle may need to make an emergency lane change to avoid hitting a toolbox, crate, or other cargo that I may be carrying as I use my truck to work with. 2 of three times I was made aware and returned to clear the roadway further endangering myself. I have current cleared my pickup bed of all cargo as I no longer trust the tailgate from spewing cargo to the roadway.

GM Infotainment Center unreliable and comes on when it feels like causing a panic while you are driving. I have taken it to the dealer twice and was told it is a known issue with no help in sight. The truck has less than 2000 miles on it.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the vehicle was experiencing unintended acceleration. The contact stated while pulling into his driveway and slightly depressing the accelerator pedal, the vehicle speed increased continuously. There was no warning light illuminated. The contact stated that he depressed the brake pedal and the vehicle responded as needed. The contact stated that the failure recurred several times while driving, and nearly caused a crash with another vehicle on one occasion. The vehicle was taken to the dealer several times; however, the dealer could not duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 2,000.

I am writing to bring to your attention a recurring issue with my recently purchased 2023 Chevrolet Silverado, documented in detail here: [XXX] . Despite the evidence presented in the document and my personal experience, Chevrolet claims there is no known issue with my vehicle. The persistent problem involves a front-end squeak chirp, which significantly impacts the driving experience. There is less than 7000 miles on my new 2023 Silverado. I am reaching out to seek your assistance in addressing this matter, as it appears to be a broader concern affecting multiple Silverado models. I believe your involvement can help ensure that both my specific case and the larger issue are thoroughly investigated, and appropriate actions are taken to rectify these ongoing problems. Your prompt attention to this matter is greatly appreciated, and I look forward to a resolution that ensures the safety and performance of my vehicle.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed and attempting to complete a turn, due to the placement of the controls on the steering wheel, the contact unintentionally activated the cruise control. As a result, the vehicle quickly accelerated to the speed last set that had been stored in the memory, almost causing a collision with the vehicle ahead. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The manufacturer was not notified of the failure. The failure mileage was 200.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving 10 MPH, the tailgate independently opened, causing tools to fall onto the roadway. No warning light was illuminated. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the failure was due to a faulty switch on the tailgate. The tailgate switch was replaced, and the vehicle was repaired. The manufacturer was made aware of the failure and stated that the VIN was not included in a recall related to the failure. The failure mileage was approximately 2,500. The VIN was not available.

Turn signal indicator on front passenger side has already failed and the vehicle has less than 4000 miles on it

There is a noticeable clunking or knocking noise from the rear suspension, possibly the leaf springs

Engine oil cooler lines began leaking oil at 800 miles. Oil leak appears to be at engine connection for line. Took to dealer where vehicle was purchased. They added dye to engine oil and clean up evidence of leaks. Told me to drive for 300 miles and call if it leaked again. It leaked again and dealer is non responsive to request for repair. Will try another dealer. Leak is significant.

Windshield wipers have stopped/paused during operation on two occasions midway through clearing rain from the windshield while driving down the road during rain events. Each time this has happened, the wipers have paused for approximately 2 seconds and then continued working without adjusting the controls. The vehicle is available for inspection upon request. If the wipers had not started working again, I could have lost the ability to see while driving on the roadway. This could have put me and family at risk of crashing, as well as other motorists on the roadway. The problem has not been evaluated at the dealership yet. There has been no lights, lamps or warnings this was going to occur either time it has happened.

2023 Silverado 1500 3.0 Duramax. Transmission failure and engine overheating at 5k miles. I was towing a trailer when the 1st transmission failure occurred. The engine shut off, and said shift to N to start while coasting with loss of power braking. I was able to get started but transmission would slip when shifting above 1st gear. I had to tow to the nearest level point to safely park the vehicle, for fear of rolling backwards down 8% grade. At that point the computer was showing engine overheat loss of power warnings. GM roadside assistance towed to nearest dealer, refilled transmission with fluid, and put me back on the road for it to fail again in traffic (loss of power / unable to move). I have now been without vehicle going on 30 days and worry there is more wrong with the vehicle than just a blown transmission (latest GM diagnosis with no repair eta). For a few hours prior to failure I noticed what seemed like the transmission hunting for gears at lower speeds (0-25) with hesitation. Could have been slipping. And also noticed strange / louder than usual turbo noises. I worry the system is generating too much pressure or has mixed oil with coolant somewhere, based on finding atf, coolant, and engine oil near the overflow and all over the bottom of the vehicle. GM support has been atrocious and someone should step in.

The audio from the stereo will cut out for all services, FM, Sirius XM, Apple CarPlay , phone. It’s happened twice within two weeks. Once I reset the stereo in safe mode., it works again.

Front left turn signal doesn't work all the time

Vehicle sways/wobbles on grooved pavement. Magnified immensely when towing a trailer. Threatens to pull you into other driving lanes. Service technician and service manager at dealership state it is a known condition with the type of tires Chevrolet has put on the vehicle and that Chevrolet is refusing to do anything about it. Multiple dates and is repeatable.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while the vehicle was parked, the rear passenger’s side window suddenly shattered. The vehicle was towed to the dealer, who had not yet determined the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was unknown.

The automatic emergency breaking never worked. I took it to the dealership and they told me the computer didn't show anything wrong. I could tell the safety features weren't behaving properly though. While I was driving the breaks completely failed. Luckily I controlled the vehicle to a stop. Every light on the dash was on. I turned the of and restarted it. When I did the break peddle pumped repeatedly on its own hard back at me and made an awful noise. The check engine light came on and stayed on. From that point I tried to get to a safe location to call a tow truck to take the truck back to the dealership. While I drove I managed to get some video of the detection system as I closed distance to the vehicle ahead it saying the gap was widening and the car right in front of me would disappear. Then as the vehicle would pull away, the sensors would say the gap was closing. My safety and others was absolutely put at risk. If anyone would have been ahead of me when the breaks failed it would have been a deadly colission. After I told the dealership there was an issue and they told me I was wrong, then this happened, they have confirmed there is a problem and have had the truck for over a week trying to repair it. It has not been inspected by the manufacturer, police, or insurance reps. There was no warning lamps prior to the failure. The only symptom was that the safety features that were stated to be on the vehicle never worked. The truck was specifically marked to have automatic breaking, safety assist, front pedestrian breaking, following distance indicator, and forward colission alert that never worked on a brand new vehicle that never worked from the day I purchased the vehicle. I did report it by calling and even bringing the truck in to be looked at and I was told there was "no issue" by the dealership. Then the break failure took place.

GM Infotainment system repeated intermittent malfunctions. Safety concern: Repeatedly (~20%) while driving, the audio from the car radio will spike to full volume for about 5 seconds, then the infotainment system will reboot. THIS IS VERY UNSAFE as it is startling to the driver, nearly resulting in multiple crashes. This is an issue reported by multiple owners, as evidenced by a simple Google search of '2023 silverado volume spike'. GM has refused to acknowledge this and has not issued a fix.

We purchased a 2023 Chevrolet Silverado High County on Thursday, August 10, 2023, at Reed Chevrolet in St. Joseph, MO. On August 19, 2023, the infotainment system failed on the vehicle. It was returned to the dealership for repair. In coordination with General Motors, the dealership could not fix the issue. They said a new infotainment system was required, but they did not have a strategy or solution to our problem. They indicated this was a supply issue, and they could not get an infotainment system as it was back-ordered. On September 11, 2023, the dealership had to trade us vehicles as they could not provide a time frame for repair. We had to give up the 3.0 straight 6 Duramax diesel we wanted and go with a gasoline version. In communication with GM, they were aware of this problem, based on the careful wording of their responses and the 2021-2023 model year Silverado pickups. I researched these model ears and found this was a common problem among many Silverado owners. GM is also well-known for this issue infotainment issue and has settled a previous class action lawsuit for different model years. GM needs to be held accountable for this issue. I look forward to your response. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We purchased a new 2023 Chevy Silverado in approximately January 2023. The onset of the problems with the new truck was Friday, August 4, 2023. The engine light came on, skipping occurred when accelerating - powertrain issues. While driving at various speeds, the vehicle hesitated and was jerking when shifting between the first and second gear. No warning lights were illuminated. Then after arriving home, the truck cut off and I attempted to re-start the car without success. Waited for some time to start the truck, but it would not start. Attempted to start again after several hours. Did not start until the next morning and was able to drive the vehicle to the Chevy dealership service department, The service department kept the vehicle from August 4, 2023, to August 10, 2023. We were not provided with another vehicle, while they worked on mine. The second time occurred 10 days after picking the vehicle up from the service department. Monday, August 21, 2023, to PRESENT. Same issues with the truck continued. This issue has caused a major inconvenience. Not only are we still making payments on the vehicle. We have not been given a date of when the vehicle issue will be resolved. The parts needed are on back order. The truck has been in the dealership service department for 22 days as of 09/05/23.

I was driving Eastbound on highway 150 on my way to work. I have adaptive cruise control in my truck and have used it many times before on this exact road with no issues. Traffic was moving slow and the adaptive cruise control was following the car in front of me exactly how it is designed to do (ACC can be turned on at speeds as low as 5 mph in this vehicle and can come to a complete stop and restart movement from a complete stop). I drove through a section of this road right after the lake crossing where the morning sun was pretty bright directly facing us for a few seconds. During this time my foot was off of the accelerator and brake as instructed by the vehicle manual for safe operation of the ACC system. In these few seconds the truck unexpectedly accelerated aggressively with no warning and before I had a chance to react the truck rear ended another vehicle, pushing it into the car in front of them as well. I have been found liable so far by insurance. I am trying to argue on my behalf. I firmly believe I am not personally liable for this accident. The system in the truck is supposed to fail safe (meaning when meeting uncertain variables, such as low camera visibility, the vehicle should disengage the ACC instead of aggressively accelerating with no information of what is in front of it) and it did not in this circumstance. As stated, I had no input to the accelerator or the brake at the time of the accident according to the owners manual safe operation of this system. The vehicle FAILED to disengage the ACC system as it was supposed to and caused an accident I had NO TIME to react to by aggressively accelerating without any warning. The vehicle has been appraised for repair by the insurance company and was found to have $7000 in damages.

Rear view camera has moisture that builds up within the lens and makes it difficult to see what is behind when reversing. I've read online about many others complaining of similar issues from different source websites.

Vehicle experiences unexpected sudden acceleration, usually at low speeds. Engaging the brake will stop it.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 65 MPH and towing a 4,000-pound travel trailer, the contact noticed that the turn signal warning was illuminated and indicated that the left turn signal was not functioning as needed. The contact drove the vehicle to a small auto parts dealer to purchase a new signal bulb. The contact was changing the turn signal bulb and smelled a burning plastic odor and noticed that the wiring harness connected the trailer to the harness on the trailer hitch appeared to have melted. The contact stated that the connector had melted. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the trailer hitch connector and wires underneath the vehicle had melted also. The vehicle had not been repaired. The manufacturer has been informed of the failure. The failure mileage was approximately 2,000. The contact stated GM is refusing to fix the problem under warranty.

This vehicle is equipped with remote tail gate release which can be activated without the knowledge of the driver allowing items to fall from vehicle and promote a dangerous outcome. An example is this morning the tailgate released after I stopped at a gas station and I had a piece of equipment fall from the vehicle. Thankfully no other vehicle was struck but this does pose a safety risk

The backup camera intermittently turns off in low light, thus rendering it ineffective at night. It's been identified with NHTSA ID Number: 10234211. However, there is no fix. I feel this is a safety issue as the camera does not work correctly in low light. It has been this way for approximately 6 months, since I purchased the vehicle.

The PCV system plugs up in below zero weather casing the main rear engine seal to blow and leak. Currently waiting for gmc to manufacture the seal as it’s been back ordered due to so many engines needing this part. Estimate is 2 months or more wait. A loud ‘pop’ was heard the day before leaking. It sounded like an object hit under the truck. Oil drops were found the next day and dealership found the leak. Gateway in Fargo, ND is the mechanic and GMC is paying for repairs. If we were to of driven for a prolonged time, the leak could have poured most of all of the oil out of the blown seal and ruined the engine. There were no warning signs. The oil pressure seemed unstable the immediate days afterwards before being looked at. It was going down and coming back up after warming. The oil began leaking faster and in larger amounts as weather warmed above freezing.
