The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at various speeds on several occasions, the vehicle lost power and then stalled. The vehicle was restarted after each failure. The check engine warning light was illuminated, and the message "Reduced Acceleration - Drive with Care" was displayed. The vehicle was taken to a dealer on several occasions, and the dealer retrieved DTC: P2732 and P0700. The contact was informed that the valve body needed to be replaced, and the transmission was leaking transmission fluid, but the leak was not located. The valve body was repaired, and the transmission fluid was topped off, but the failure reoccurred 2-3 months later. The manufacturer was not notified of the failure. The failure mileage was 10,900.

On 04/03/2026 at approximately 0545 I was heading in to work . While at a complete stop I proceeded to accelerate on the Highway 54 BRF WI. 54615 when the truck made a clunking noise and jerked. At which point the engine light turned on along with reduced speed message across the display screen. unable to pull over safely at the moment I had to proceed no faster than 25 MPH on US 54 hindering all traffic behind me. once safely pulled over I placed the truck in Park, then neutral , which made a loud clunking noise and absolutely no reverse. Truck towed to local dealership. Vehicle had been inspected by Dealer tech. Tech stated faulty valve body in the transmission.

When driving at slow speeds, less that 10 MPH, the engine shuts off and vehicle shifts to neutral. Message is displayed on driver console Press Start Button to restart. Only the engines shuts down as all displays, entertainment center and controls are still displayed. Pushing the start button restarts the engine. This has occurred several times since purchasing the truck however it has occurred 2 times in the last 45 days. This issue has happened while driving in slow traffic on the interstate and is concerning when it occurs as I come to a complete stop without warning creating a possible rear end accident. It was first reported to my Chevy service dealer on 2/21.2025, The Chevy tech stated they could not duplicate the issue so no remedy has been offered. The issue continues to happen and I will be returning to my Chevy service center for another report of this continuing to happen.

Turning into the driveway and the truck shut off. Place in park and the truck started right back up.

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from Ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the Lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home.(this part of not going in reverse I do have on video) Once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave Walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video as well).

The 6.2L V8 motor is known to have faulty internals. I was driving down the highway and the motor shut off. The vehicle needs a new motor now. GM has offered an oil viscosity change to 0w-40. That was done 20k miles ago. This vehicle now needs a new motor

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving approximately 55 MPH, the vehicle started jerking and shuddering before it stalled. There was an abnormal grinding sound coming from the engine compartment. There was no warning light illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not associated with the recall. The manufacturer was informed of the failure. The failure mileage was 13,222.

Purchased June 3,2024 Feb 3/2025: serial data gateway module recall. All indicator lights on, ac control and radio inoperable, instrument panel displays various issues. That recall was serviced. February 28/2025: couldn’t see how fast I was going, don’t know how much gas I had. AC controls and radio no operable, all information indicator lights on again March 1/2025: duplicate issues from 2/28 January 17/2026: at a red light, car shut off and wouldn't turn back on in the middle of snowing road, indicator lights all on and present could not restart car, police present-had to unhook battery due to safety concerns March 18/2026: , all indicator lights on, speed limitation to 62 on the highway, loss of power steering, didn’t turn back, called for tow and the morning after turned on and check engine light off Vehicle in at dealership: March 26-27, 30-31: Could not replicate issue, no r/o codes 4/1 Contacted by Brian with GM Corporate- “can’t do anything until the check engine code goes off again”.

truck shut off while driving in traffic managed to steer it off the road, towed to dealership with p0016 code as well as a bunch of others. known recall issue passed gm pico test a month earlier. now when I log in here to view recalls it says 0 recalls not repaired. Now truck has to get a new engine.

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

1. Transmission shudder at highway speeds between 64 and 83 miles per hour. 2. Pour fuel economy; 12.5 mpg @ 65 mph, 11.8 mpg @ 70 mph, 8-9 mpg @80 mph towing a 2025 utility trailer wiith motorcycle approximately 1800 pounds.

I am writing to report a serious safety concern involving my 2024 Chevrolet Silverado that resulted in a child being locked inside the vehicle with the key fob present inside the car. On March 25 2026, after parking and turning off the vehicle, I exited the driver’s seat with my key fob inside my purse, which remained in the front of the vehicle. I then walked around to remove my daughter from the back seat. During that time, she climbed into the front seat and pressed the interior door lock button, locking all doors. My daughter has autism and is not able to follow instructions or unlock the vehicle on command. As a result, she was locked inside the vehicle with the key fob present inside, and I was unable to gain access from the outside. The vehicle did not prevent the lock from engaging, nor did it allow me to open the door despite the key being inside the vehicle. This situation required emergency assistance (911) to safely remove her from the vehicle. I understand that many vehicles have “lockout prevention” features; however, in this case, the system did not account for a vulnerable occupant inside the vehicle. Allowing the vehicle to be locked from the interior while the key fob is inside—and without any external override—creates a significant child safety risk. I am requesting that Chevrolet review this design behavior as a potential safety issue, specifically: - Why the vehicle allows interior locking when a key fob is detected inside - Why there is no external override to unlock the vehicle when the key is present - Whether a software update or safety feature enhancement can address this risk This is not just a convenience issue—it is a safety hazard that can lead to dangerous outcomes, especially for children or individuals with disabilities. Please confirm receipt of this concern and advise whether this issue has been previously identified or is under review.

I had my oil changed and the next day the check engine light came on. I looked on the Chevy app to see what it was and it said Varuable Valve timing issue. I Click further into the app warning and it said, Engines equipped with this system use sensors that regulate the opening and closing of the intake and exhaust valves to optimize performance and efficiency. I live 3 and a half hours away fro. The dealership so I had some mechanics look at the truck just to see if they could pin point what the issues was exactly. They didnt pull or work on anything just looked around listened and plugged in a code reader. The code reader found some codes that had to do with 3rd stage valve timing issues and VVT. And 1 or 2 other codes. But they didnt know exactly what was wrong. I had my oil changed 1 more time to see if maybe that was the issue. It did not fix the issue. I called the dealership to make a appointment. I brought it in and get a call that the cam shaft need to be replaced. It was in the shop for about a month and when they said it was ready. I went to pick it up and as I was pulling out of the dealership parking lot. The check engine light came on and I drove back and it had the same codes. And now it is being worked on again. The safety side is if it looses power while im going 65 mph it could be really dangerous. Becaue there could be metal shavings in the oil possibly.

My truck engine stopped working while driving down the road causing me to lose power and I was not able to exit the roadway. There were no warning or messages until the loss of power and dash stated to "restart the engine". This was not possible. The truck was towed to a Chevy dealership and they confirmed the engine seized up do to unknown engine failure. This is a 2024 6.2L engine with 45000 miles that is NOT under recall. The dealership replaced the engine under the powertrain warranty.

I was driving down the highway and the vehicle suddenly shutoff without any warning. I coasted down an off-ramp and came to a stop in the middle of a round about. The vehicle would not re-fire and had to be towed to dealership. When at dealership it was discovered the engine failed. This is a 2024 6.2 liter engine that was not included in recall. I could have caused an accident on the highway as I suddenly lost power. People who were included in this recall received a 10 year 150K warranty on the new engine. My truck should be included in that.

The DEF tank failed making the exhaust system malfunction. This puts the vehicle in limp mode.

On 1/31/2026, while returning from an AKC event with my XXX year old border collie, I was traveling on IXXX at approximately 70MPH in the left hand lane passing other traffic. As I started up a hill in a remote area, I began to hear a knocking sound coming from the engine compartment that sounded like a rod knocking and the truck began to struggle to continue up the hill. It then lost all power, a message stating to shift to neutral and restart flashed on infotainment screen, I shifted to neutral and pushed the start button, but everything went blank. I had to struggle to merge back into right lane and eventually over to the breakdown lane, approximately 5 miles from the nearest exit. I was forced to remain on the side of a busy interstate for approximately two hours during an unusually cold day for Florida that consisted of snow flurries while waiting for roadside assistance. Luckily, I was able to arrive at the dealership 5 minutes before closing and was able to get my truck checked in. The service writer knew exactly what the likely issue was when I described my ordeal, and it was partially confirmed when she pulled the Christmas tree of codes from the computer that my truck was throwing. It should be noted that the truck would not restart after the catastrophic failure that stopped the motor at 70MPH on the interstate and would not shift to neutral for the tow truck operator to load or unload onto flatbed. Subsequently, Techs determined that engine failed due to suspected internal damage to crankshaft and motor was replaced under warranty along with torque converter. The failed engine serial number was [XXX] but I was never notified or included in current recall 25V274, It did not show as active recall in GM App nor was it inspected during LOF visits at various GM Service departments. My truck was in GM service from 1/31 - 2/21 for the engine replacement, Mileage on 2024 Silverado 1500 High Country was 25,274 at failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Component: Faulty coolant control valve causing reduced acceleration and check engine light to come on. Fan is constantly on when reduced acceleration is displayed. Safety: can overheat, reduced acceleration can cause an accident. Problem reproduced: Dealer did check and confirm codes and errors. Dealer confirmed item failed. Coolant control valve needs to be replaced.

The tailgate has opened 4 times while I’ve been driving. There was one incident in which an object in the truck bed fell out onto the road. Other drivers are at risk for serious injury or death due to objects falling out. I have read other incidents of this happening online to the Silverado 1500 models however Chevy has only issued recalls for the 2500 and 3500 models. The problem has not been reproduced or confirmed by the dealer and they will be inspecting it in the next coming days. There were no warning lamps or messages indicating failure or that my tailgate was open. I’ve provided photo documentation showing me closing the tailgate as well as a photo of the object falling onto the road.

After taking in to dealer for recall diagnostics and higher viscosity oil change a couple months later. Heard a noise while driving on interstate, lost cruise control, stability system, engine light came on with a ECS. Kept driving on the interstate until we got to a red light and the engine died. Cranked starter but hard to start and ran rough and died multiple times. Feathered throttle to get over 1K RPMs to get it off the street. Towed to nearest Chev dealer. P300 code. Tore engine down. Here is what dealer documented: CUSTOMER STATES CHECK ENGINE LIGHT IS ON WITH SERVICE TRACTION & SERVICE ESC MESSAGES. ENGINE IS RUNNING ROUGH AND WILL STALL. TOW IN. Valve Spring Replacement - Replacing the faulty valve spring on the cylinder 7 exhaust side is necessary as it is causing the exhaust valve to remain stuckopen, leading to engine misfire and over 80% leakage in that cylinder. This service can help restore proper engine compression and improve engine performance. Op.1 CEL -CEL: Customer states 1. replaced the exhaust valve spring and valve spring seal. reinstalled components with new seals and cleared dtcs. started engine and verified the engine starts and runs but having multiple cylinder misfires. reset engine fuel trims and brought engine to operating temperature and let it run for some time. other cylinder misfires went away but still found a dead misfire on cylinder 7. removed and swapped spark plugs with no change. noted the spark plugs have some exhaust build up on the tip due to the faulty exhaust valve spring. performed a static compression test and found the compression to be 175 psi and a running compression test with a smooth build up to 125 psi. checked spark and spark was good. tested the injector system using the AFIT test and found the test to pass indicating no faults with the fuel injectors. performed a cylinder leak down test and found no cylinder leakage coming from cylinder 7. put engine back together and cleared dtcs. reset the throttle

GM replaced engine after a complete failure associated with a defective engine recall. The remanufactured or new engine installed seems to have a similar defect as the original engine. Returned vehicle for service and was told GM refused to repair or replace the engine until the vehicle suffered another complete engine failure. Regardless of any safety concerns of an another complete engine failure.

At just over 36,000 miles, the vehicle randomly started jerking to either side of the road. It's not continuous and happens at random intervals while driving. Sometimes the steering wheel would jerk with the movement of the tires, other times, it felt as if the steering wheel had disengaged for a moment. The first time it happened, we were traveling on a highway at 55mph and were jerked towards oncoming traffic. I immediately stopped the vehicle and turned around to head back home at a safer rate of speed. The steering issue continued numerous times until my arrival at home. This issue just happened today, so it has not been inspected by anyone yet. There were no warning lamps, messages, or other indications.

The dealership has informed me that the Radio Control Module of the vehicle needs to be replaced. The infotainment center which contains the backup camera is no longer functioning.

Transmission failed at 15000 miles. Attempted to shift to reverse and instead car went into neutral. Allowed me to shift into forward but quickly went into “limp mode” once underway. Seems like the same issue as many similar gm trucks have had with transmissions but my 2024 is not included in active recalls when searched by VIN. Suspect it probably should be since issue appears to be the same as those that are.

Was driving 45 mph when a “ Conditions Not Correct for Shift” warning pops up on the screen and puts me into neutral, but came to a stop in a neighborhood entrance and have not been able to start or put the vehicle into gear

My engine shutoff while I was driving on the highway. I had the initial recall remedy performed on my 6.2L 2024 silverado truck by getting the thicker oil about 8 month's ago. Now my truck is in the shop I'm suppose to be getting a replacement engine. I'm not sure if I can trust the replacement engine im getting.

2024 Chvrolet 3.0 Diesel is losing oil at 3k miles on every oil change. DTC P06DD , dealership did an oil consumption test, they have determined there is signifcant oil loss after every oil change after 3k miles. Truck is at 71k miles. Engine power loss while driving, check engine light on, drove straight to the dealership.

After engine blows due to recall and engine not running, it is impossible to shift the electronic transmission into neutral mode for towing. This happened to me in November of 2025 and I was recently told that I should report the issue. Neither the tow truck operator nor myself were able to get the vehicle into neutral without the engine running. I could have easily been stuck in the middle of traffic and no one would be able to help me move to a safe location. Some way of easily getting the vehicle into neutral without the engine running needs to be added to all Silverado’s with electronic transmissions.

In May 2025, we received notice that my truck was involved in GM Safety Recall N252494000. In July 2025, a fuel consumption test was performed because the vehicle showed low oil pressure and was 2-1/2 quarts low. Chevolet indicated "consuming oil" was normal; however, I have owned trucks for 25 years and have never "consumed oil". In October 2025, we received notice that we could finally schedule the engine inspection at a Chevrolet Dealer of our choice. We scheduled this appointment for Monday, November 17th, 2025. The Picoscope Inspection was performed and the engine passed. They installed new higher viscosity oil, new oil fill cap and insert; but they note that the vehicle had no oil on the dipstick and would like to have another consumption test performed in 2000 miles. The next day, Tuesday, November 18th, 2025, the engine failed. The initial diagnosis was a continuous misfire of cylinder #3 requiring a Valve Lifter Replacement on Left Side. Upon completion of this work, they identified additional issues including spun crankshaft thrust bearing and damage crankshaft journal requiring replacement of the 6.2L engine. The engine failure occured the day after the proposed recall "fix" indicating that the picoscope test and higher viscosity oil is not an effective remedy. I brought up concerns about the consumption of oil multiple times with the Chevy Dealer multiple times and the response is "oil consumption" is considered normal with this engine. Not having my vehicle created significant hardships as I work in construction. I did not have a toneau cover to secure my tools, I did not have the ability to use my toll pass on the highway, I could load construction materials into the rental vehicle, and I had to switch between 4 different rental vehicles during the course of the 65-Day Repair!

Vehicle died and would not move forward or in reverse. The engine locked up and had to be replaced. Recall to test engine and replace with thicker oil was performed 6000 miles previous to engine failure.

The cam crankshaft failed. I was driving on the highway at a speed between 65-75 and my truck just cut off without any warning. Luckily, I was in far right lane and coasted over to the side of the road but it was very scary because I didn't control my truck at all. I called the nearest Chevrolet Dealership that was Kevin Whitaker and they give me the Chevrolet help contact phone and they sent a tow truck to pickup my truck about 1 hr later and I was stuck in my truck on the side of the road and I couldn't get out on the drive side because how close it was to oncoming traffic. Once I arrived at the dealership with my truck after asking the tow driver could I ride with him to the dealership. At the dealership they checked the truck with computerized device and the service advisor told me the truck code revealed cam shaft problems. I told him that I did see and warning sign saying low oil pressure once I tired to start up the truck again on the side of the road.

I have a 2024 Silverado with the L87 (6.2) engine. I brought in in for recall. After inspection the Chevrolet Service Center said it was good. They changed the oils to 0-W40 per the recall. On January 8, 2026 I was driving at 35 mph and the engine just stopped. I had it towed back to the Chevrolet Service Center and after diagnosis it was determined that the engine failed and has to be replaced which take a month or more.

Engine burning massive amounts of oil, noticeable tick in engine, dealer request I bring it back every 500 miles for a total of 2000 miles to assess wether or not there’s a fault, when I requested for them to keep it diagnose it in their own way without forcing me to continuously have to return to the dealer (4 different times) for a conclusion

5449 miles. Motor had a knock. Took to dealership and they replaced valve lifters

Vehicle simply died in the middle of an intersection and blocked the roadway for an extended period of time before being towed back to dealer. Engine failure confirmed, replacement has been ordered

Thrust bearing failure at 11,945 miles requiring complete engine replacement.

Engine safety concern. Grinding and clunking while engine is running and gets worse under load or when accelerating. Have taken into dealer for service over 6 times. Recall service was performed and their fix was to change to a thicker oil but all that caused was worse fuel economy, more expensive oil changes, and the noises have become worse. Going back to dealer next week for another attempt. Have requested lemon replacement with GM but they are denying any issue.

Vehicle: 2024 Chevrolet Silverado 1500 High Country Engine: 6.2L L87 V8 Recall: N252494001 – L87 Engine Loss of Propulsion I am submitting this complaint to report a serious safety defect involving my 2024 Chevrolet Silverado 1500 High Country related to NHTSA Safety Recall N252494001 (L87 Engine – Loss of Propulsion). My vehicle experienced a sudden engine failure consistent with the conditions described in the recall, resulting in loss of propulsion. Due to this failure, General Motors authorized a full engine replacement at an authorized GMC dealership. After the engine replacement was completed, the replacement engine also failed in the same manner as the original engine, again resulting in loss of propulsion. This second failure occurred despite the vehicle being repaired according to General Motors’ recall procedures and specifications. Loss of propulsion creates a significant safety risk, especially while driving at highway speeds or in traffic, as it can lead to sudden power loss without warning and increases the risk of a crash. Despite the replacement engine failing in the same way as the original recalled engine, General Motors is now refusing to replace the second failed engine or provide a permanent remedy. As a result, my vehicle remains unsafe to operate and unresolved under the existing safety recall. I am concerned that the recall remedy is inadequate and that replacement engines may also contain the same defect, creating an ongoing safety hazard. I am requesting that NHTSA review this matter to determine whether the recall repair is effective and whether additional corrective action is necessary to protect vehicle owners.

Vehicle does not indicate proper DEF level. Vehicle has stated several times that it is out of DEF but is not. The most recent time the vehicle was at a dealer and was noted as normal operation. Driving up to going the dealer: vehicle displayed message “DEF empty refill now vehicle speed restricted to 65mph”with a 500 mile count down. Vehicle was driven 489 miles of the 500 miles. Vehicle was taken to a dealer. Dealer confirmed that vehicle was not out of DEF, vehicle was at 40% DEF capacity (~2 gallons of fluid in a 5 gallon tank). Dealer noted that this was normal operation. This is not safe, the DEF system isn’t accurately reporting level. In other situations it hasn’t recognize DEF fills. This can potentially lead to the vehicle severely restricting speed or not allowing the motor to restart creating unsafe conditions for the passengers and other vehicles on the road way. Vehicle was under warranty at the time of the issues. Vehicle is currently just under 37,000 miles.

Fuel rail pressure low during engine cranking

Transmission pauses from 1st and 2nd gear. Causing to have no acceleration from a stop. Can cause safety issue to accelerate while pulling in front of traffic. Truck has been to the dealer. Dealer says no codes triggered but the pausing still persists and is only getting worse. Truck has been doing it since around 30,000 miles. Truck currently has 36,760 miles.

Formal complaint — outdated Android/Google Built-In security patch level on 2024 Chevy Silverado; potential cybersecurity defect and negligent maintenance by manufacturer. I am submitting a formal complaint regarding a critical cybersecurity and software maintenance defect in my 2024 Chevy Silverado. The vehicle runs Google Built-In / Android Automotive OS with an Android Security Patch Level of February 2024 (as displayed under Settings → About → Android version). As of this writing in December 2025, this patch level is nearly two years outdated, with no available over-the-air (OTA) updates and no clear communication from General Motors or Google regarding continued support or end-of-life status. This condition exposes the infotainment and telematics systems to known and documented vulnerabilities, representing both a cybersecurity defect and potential consumer safety. Description of the defect: The infotainment system reports “Android Security Patch Level: February 2024.” Attempts to check for updates return “Your system is up to date.” The system shows a red exclamation mark beside the patch level, indicating a fault condition or known update gap. Neither the dealer nor OnStar/Customer Support can apply an update manually or clarify the support cadence. This leaves the vehicle permanently exposed to Android-level vulnerabilities discovered and patched long after February 2024. Security and regulatory implications: The infotainment system runs a network-connected OS with Bluetooth, Wi-Fi, cellular, and vehicle bus access. Unpatched Android components are subject to hundreds of known CVEs since February 2024 — including privilege-escalation, RCE (remote code execution), and Bluetooth/Wi-Fi stack vulnerabilities. The U.S. NHTSA Cybersecurity Best Practices for the Safety of Modern Vehicles (2022 update) and ISO/SAE 21434 require that manufacturers maintain timely security updates for all connected vehicle systems.

Formal complaint — persistent, non-disableable Bluetooth transmitter in [2024 Chevy Silverado] / privacy & safety risk; request for remediation and recall assessment I am writing to file a formal complaint regarding a safety and privacy defect in the infotainment/telematics system of my vehicle, a The unit runs Google Built-In / Android Automotive OS. This complaint documents technical evidence that the vehicle’s Bluetooth radio broadcasts a persistent, non-randomized MAC address and cannot be completely disabled via any user-accessible control. I request immediate remediation, a formal security assessment, and confirmation whether this condition will be remediated by firmware/OTA update or recall. Summary of the issue The infotainment unit’s Bluetooth adapter emits BLE advertisements that expose a static, permanent MAC address i.e ([AA:BB:CC:DD:EE:FF]) that does not change across power cycles and is visible to passive scanners while the vehicle is parked and otherwise idle. The vehicle provides no persistent user control to turn off the Bluetooth radio; menus do not disable the hardware radio. Attempts to disable Bluetooth via the system settings are ineffective. The static MAC and inability to disable the radio create an ongoing privacy and tracking risk: third parties can uniquely identify and track the vehicle across time and locations by logging the broadcasted identifier. This configuration is inconsistent with current industry cybersecurity & privacy guidance that recommends minimizing exposed identifiers, providing user control to disable wireless interfaces, and implementing randomization of wireless addresses when possible. The static MAC plus non-disableable radio constitutes a persistent, unique identifier broadcast in public spaces. This defeats reasonable efforts by consumers to limit tracking and to control their privacy.

Truck was purchased Aug 2024 During first few months, I felt a shudder/vibration when either holding speed and/or slightly accelerating between 30-45 mph, usually at 1100-1300 RPM. Current Odometer 33,995 In the last month the truck has began to vibrate worse. I have a "Rumblestrip" feeling when at the same speeds. More noticeable on surface roads when following behind traffic at 30-45 mph. Generally the shudder is felt at approx. 1100-1300 RPM. Took the truck to the dealer yesterday, and they performed a quick roadtest. Service Tech was able to feel the rumble strip shudder multiple times, however their diagnostic tool only indicated a TCC Slip 2 times during a 20 min drive. The shudder/vibration happens when in "D". It is not present in "L9", or in "Tow Mode". The shudder feels worse in 4WD. If the shudder/vibration is happening, I am able to hold the speed and RPM at the current spot, the sensation is continuous and does not go away unless I accelerate or decelerate. I tend to feel it more when on an incline, and decelerating. As or right now the data has been sent to GM for diagnostic viewing. Found multiple TSB for issue with 2500/3500 models, and 1500 models from prior years. L84 Engine - 2024 Silverado 1500 RST

hard/delayed shifting, slipping, shuddering , like rumble strips at certain speeds. Jerking, bucking, or significant delays when shifting gears. Shuddering/Vibration: A feeling like driving over rumble strips, especially at certain speeds and when warm

On [XXX], I [XXX] ) experienced the following issues with my new 2024, Chevrolet Silverado - 1500: • Front Windshield Wiper Washer Fluid not spraying/dispensing. • No messages or symbols displayed on the Driver Information Center dashboard indicating Windshield Wiper Washer Fluid Reservoir low/empty. • Inspected the reservoir that holds the fluid and did not observe low/empty. • Took it to the GM dealer 4 times and they were unable to repair. My vehicle has a recurring defect with the windshield washer system where the washer fluid does not dispense when activated. This issue occurred on a new vehicle and has persisted despite service attempts. When the washer fluid fails to spray, I am unable to clear dirt, dust, road debris, or moisture from the windshield while driving. This significantly reduces forward visibility, especially at freeway speeds or in conditions where debris from other vehicles hits the windshield. The inability to clear the windshield immediately creates a safety hazard because it can obstruct the driver’s line of sight and increase the risk of a collision. This issue is not cosmetic, it directly affects safe operation of the vehicle and the driver’s ability to maintain visibility during normal driving conditions.

The radio cuts out which then kicks my cell phone off/navigations kicks off every few minutes. On one occasion the speedometer stopped. This cutting out makes it unsafe to drive because you are messing with the radio trying set up phone again or trying to get the navigation going again etc instead of paying attention to the road. over the past 1 plus years i have vearved off the road. i have had my truck in for repairs 7 times in 3 different dealerships. they have replaced the radio twice (found out later the 2nd time was a lie), a coaxial cables , and amplifier. i am told the same problem is happening on numbers GM vehicles and GM does not have a fix. I have requested my money back 3 times due to the safety of driving as is.. Gm have given me the run around all through it. they are aware of the problem but do not know how to fix. My third request did get addressed but was denied because they said the lemon law is only good for one year. I am about to run out of warranty and Gm has never fixed the problem. I am not the only one there are alot of this vechiles with this safety issue. i need someone to help protect myself and my family. GM needs to be forced to refund everyone money since they cannot repair these vehicles to make them safe.

Regarding Recall Repair on My Truck To Whom It May Concern, I am writing to formally express my frustration and concern regarding the recent service performed on my truck, which I purchased pre-owned from Tropical Chevrolet with only 4,700 miles. 9 months after my purchase, the vehicle received a manufacturer recall involving the motor, requiring a full engine replacement. I brought the truck to Bomnin Chevrolet West Kendall for the recall repair, expecting that it would be handled correctly and at no cost to me, especially since the truck was running perfectly before the recall work. After the motor was replaced, I was informed that the Air intake manifold currently on the truck is “not original.” This Air intake manifold was already installed when I bought the truck from Tropical Chevrolet, and I was never informed of any aftermarket or non-original parts at the time of purchase. Now, after Bomnin Chevrolet completed the recall repair, the truck has a check-engine light, and I am being told I must pay approximately $900 to change it for original air intake manifold to remove the check engine warning light. I think the mecanic took out the program.from the computer and Now they want me to pay.This is unacceptable for the following reasons: 1. The truck had no check engine warning lights and was running properly before the recall repair. 2. The Air intake manifold was already on the truck when I purchased it from Tropical Chevrolet. 3. I never approved or installed any non-original parts. 4. Bomnin Chevrolet removed and reinstalled the parts during the recall repair. 5. I should not be held financially responsible for problems created during the recall repair process. I am requesting that this matter be reviewed and resolved immediately by Bomnin Chevrolet West Kendall. The truck should be returned to me in the same conditions I gave it to them and the recall fix.Thank You Regards, Rafael Lafee

For the first time I purchased a brand new vehicle off a dealership lot…What a mistake. While the dealership itself was an awful experience I thought it was worth it for a Chevy Silverado. After all my previous one was so reliable. WRONG. The first issue I found was I was unable to shift into reverse to back out of the driveway of a fire station I volunteer at. After driving forward a couple times and shutting the vehicle off and shifting multiple times I had to be towed out in reverse. I was able to drive home but the transmissions slipped once and the vehicle slowed abruptly. The check engine light was now on. I dropped the vehicle off at the dealership over the weekend and on Monday they called and informed me the 2024 Silverado misfired once and nothing was wrong with the transmission. There was nothing they could do. About two months later I was driving to work as a career firefighter/paramedic when my vehicles check engine light came on and a message informed me that I was in “reduced acceleration mode”. I slowly and carefully made my way to work and brought the truck to the dealership after my shift. The check engine light was now on again. They informed me later that day that I had a faulty valve body in my transmission. They “unfortunately” could not give me a completion date on my repair as they had no ETA for the replacement part. It appears the part is in high demand. This makes sense as a quick google search shows this is a widely known issue with the 10 speed transmission. So far I have been unable to get a rental vehicle between the dealership and GM. Aside from my house my 2024 Silverado is the largest purchase of my life. And at 15,000 miles I am without it for the foreseeable future. As a first responder the communities I serve depend on me to respond from home at any hour. My family and I are living in a DIY renovation while also starting a farm business. I need a dependable vehicle and regret spending $53,000 on a new vehicle. I have more to say.

Hairline crack developed on the transmission cooling line at the connection of the thermal bypass block. After looking up it seems to be common. Yes, there have been user-reported issues with transmission cooler lines leaking or cracking on 2024 Chevrolet Silverado models equipped with the 3.0L Duramax diesel engine, including at or near the thermal bypass block connection. These reports primarily come from owner forums and appear to affect a subset of vehicles, often discovered during routine maintenance or after noticing fluid spots under the truck. Symptoms can include hard shifting, fluid seepage on the undercarriage, or low transmission fluid levels, with some cases progressing to require towing if not addressed early. For instance, multiple owners of 2024 Silverado 1500 models (including ZR2 trims with the LZ0 3.0L Duramax) have described leaks originating from the cooling line block or thermal bypass area next to the oil filter, sometimes involving hairline cracks in the lines themselves.  In one detailed account, a 2024 model with around 35,000 miles experienced fluid leaking from the cooling line block, leading to replacement of seals and the entire line assembly due to cracking discovered after initial repairs.  Similar problems have been noted on closely related 2023 models, where leaks at the thermal bypass valve necessitated replacing the valve, O-rings, and all cooler lines, with some users reporting hairline cracks as the root cause.  Parts like the lines have been on backorder in some cases, causing repair delays, and resolutions are typically covered under warranty (e.g., powertrain coverage up to 100,000 miles), though repeated visits to dealerships are common. These issues seem tied to the 10L80 10-speed transmission paired with the 3.0L Duramax, where the thermal bypass valve can contribute to overheating or fluid flow problems if faulty, potentially exacerbating line wear

Per the dealer, catastrophic engine failure.

The coolant control valve and the transmission control module are having to be replaced on thousands of Silverado 1500s from 2022 to 2025. Both parts have been updated, but there is no recall and many people are being left stranded due to this. Mine has not currently failed, but I am older and really don’t want to get stranded due to a known issue. Why wouldn’t they have been forced to do a recall General Motors should be replacing these as a preemptive precaution.

Complaint Description On Tuesday October 28th, 2025 while driving to work, my 2024 Chevy Silverado LTZ suddenly went into limp mode during normal driving. The truck would not go into reverse at all. I had to use OnStar to call a tow from my residence because the vehicle was not safe or able to be operated. The truck has been at the Chevrolet dealership since that day and as of today (November 7th) it still has not been repaired. The service department confirmed it is a failed transmission valve body. Research shows this is a recurring and known issue on many GM trucks and GM does not appear to have a permanent fix yet. Component/System that failed: Transmission Valve Body failure. Component is currently located at the GM dealership and is available for inspection. Safety Risk: This failure caused sudden limp mode, loss of power, and inability to reverse while in active traffic. This put my safety and potentially other drivers at risk due to sudden unexpected deceleration and inability to maneuver safely. Problem Confirmed: Yes. Confirmed by GM dealership service technicians. Inspection: The vehicle is currently at the GM dealership. No manufacturer field rep, insurance, or police inspection has occurred yet. Warnings / Codes Present: The failure occurred without prior early signs that morning. When it failed, OnStar diagnostics reported: P2732: Transmission System — “Engine and Transmission System not performing as expected.” P0700: Transmission Control Module requested Malfunction Indicator Lamp illumination. Emissions related DTC set in the Transmission Control Module. Both codes triggered at the time limp mode activated. Best Assessment: This appears to be an ongoing recurring GM transmission valve body issue affecting newer GM trucks. The failure caused a sudden loss of drive capability and is a safety hazard that requires NHTSA investigation.

It was down pouring, I needed to pull over. The electronic buttons below the big display which included the HAZARD LIGHTS FAILED to respond. A symptom was the fan speed on the display would also not disappear. The dealership said maybe it was in the middle of an update. After she rebooted it worked again.

[XXX] , a long-time Chevrolet customer and GM Family First Program participant, reports a recurring, life-threatening defect in his 2024 Chevrolet ZR2 3.0 Diesel truck. The issue centers on repeated fuel injector failures that have caused the vehicle to become uncontrollable while driving, posing serious safety risks to his family and others on the road. Despite multiple incidents and documented repairs, Chevrolet has failed to provide a permanent solution or meaningful customer support. Mr. [XXX] is requesting NHTSA’s intervention to investigate the defect and hold GM accountable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

8 Speed Transmission without any warning, started shaking and clunking and slipping while doing 55mph in traffic causing sudden loss of momentum. 8 speed transmission failure. Dealership says bad transmission control module and won’t inspect internal components. Chevy is still playing games with people with their defective 8 speed transmissions. They have not fixed all of their previous problems

We have had four previously documented issues with the electrical, brake and engine in our truck. Today, we were advised by the dealer that the truck had been fixed, and a new ECM had been installed. They advised they drove the truck for 100 miles and there were no issues. We picked the truck up and on the way home, while on the highway, the truck went into low power mode, the brakes went out, the check engine light and slip light came on. The dash began flashing detection warning lights (see attached photos): Brake system failure 62 MPH top speed, Service steering column lock, Reduced Acceleration drive with care, Service ESC, Service traction control. We immediately turned around and went back to the dealership and showed them what was going on. They took photographs and had the technician come out to look at the vehicle. He looked at the lights and codes and admitted he does not know what is going on. The service manager said that the company representative was coming tomorrow (10/21/25) and that he was going to speak with him and recommend a buyback. We left the truck with the dealer and were given a loaner car. This is the 5th incident with the same issues.

The car seat anchor system is very poorly designed and extremely difficult to use. I just spent an hour trying to ensure the seats for our grandchildren are installed correctly. The upper anchors are poorly placed, difficult to access and do not inspire confidence the seats will be secure in the event of an accident. This is after I had to take the truck in for a warranty claim because the lower car seat anchor on the back seat passenger side was covered by factory upholstery and could not be used at all. It’s very frustrating when one attempts to comply with safety regulations but poor design inhibits the proper installation of car seats.

Truck did not have reverse. Service engine came on after going forward and possible loud shudder like going over a pot hole. Not sure if it was a pot hole or transmission. Dealer fixed the valve body in Transmission after 1 week.

I have a 2024 Silverado 1500 Z71. I purchased new, within the first month I started experiencing issues related to the fuel. Stalling, dying, missing at idle and failing to start. I’ve reported it to the dealerships, with the same response unable to duplicate. Sept 22, 2025 I was driving alone rounding a curve in the road when my vehicle lost complete power causing me to loose control crashing into trees. I was unharmed physically, but mentally this hurt. To know this all could have been avoided had Chevy customer service or the dealerships listen and looked at the dtc that were clearly shown. P3187 fuel pump pressure performance low pressure. Stated failed since last cleared. Dealership did not acknowledge or discuss with me this dtc. Instead they gave me a multi point inspection stating unable to duplicate. There negligence caused me to wreck

There is a safety recall on my truck and dealer wont take it in to address the issue. I have been trying for months and they say that they are waiting for guidance from GM. We don't feel safe driving the truck. Asked for GM to buy it back and they denied, told me to find another GM service center. I tried another and they said the same thing. I'm running in circles and shouldn't be forced to drive an unsafe truck that is ~1 year old.

GM is not handle this recall in a timely manner. They are refusing to inspect vehicle to see of there are any defects. This is concerning, as based on the recall notice, the engine may fail at anytime. This could cause a crash or leave me or my wife stranded on some road. My dealer would do the inspection but to do the inspection but they said they are not allowed until I have gotten "permission" from GM. This is a safety concern for me and my family and GM is not handling this appropriately. An immediate inspection should be done ensuring if the vehicle is safe to drive.

Engine was making noise and ultimately stopped responding when I would push the gas, leaving me stranded on the side of the road. Luckily, I was able to get the vehicle off the road in time to not cause an accident. The vehicle could have stalled and seized up in the middle of the highway. This problem has been confirmed by the dealer in the attached work order invoices. It has not been inspected by anyone other than the Mountain Chevrolet dealership, to my knowledge. The dealership has the vehicle running again, but is not able to confirm if the 'new' engine in my vehicle is the one address the recall issue, reference number N252494000. Additionally, this vehicle broke down again two months later for a related issue per the additional service invoice attached. For all of these, GM has not been willing to pay for the full value of the rentals for each service, totaling over 60 days without my vehicle. I've requested this through the GM Customer Care to no avail. I would also like to receive confirmation that the 'repaired' engine in my vehicle resolves this open recall concern. I've been stranded on the side of the road twice now with this newer vehicle and would love some assurance from them. At a minimum I want GM to pay for the full value of the rental cars. For the record, I also requested GM buy-back the vehicle which they have rejected my request. Any help you can provide is appreciated. Thank you.

07/28/2025 10:35am, We had just pulled onto an Interstate ramp and the engine powered down and the dashboard began flashing errors, service engine soon light came on. The following errors were displayed: Reduce speed to 62 mph, brake system failure, Service traction control, Service ESC, Service steering column lock, Trailer brakes disabled service required. I had no brakes and had to pump them to get stopped. I was able to pull to the side of the road and shut off the engine. I called dealer and reported issue as this occurred last Tuesday. They advised to bring the vehicle in at 0800 tomorrow. I restarted the vehicle and system reset and I was able to continue. At 12:58pm, I pulled off the interstate ramp onto a county road and the engine powered down again and displayed the same errors. The brakes did not fail this time and I was able to get home.

On Tuesday we pulled out into traffic and the truck shuddered and I heard a pop. The air conditioner went out and then a plethora of warnings along with the service engine light popped up on the dash. The brakes stopped working and the truck went into a low idle almost causing the vehicle behind us to rear end us. Error messages were as follows: Brake failure do not go above 62mph, trailer brake failure, steering column needs serviced, service ecs and several others. I was able to get the vehicle back home and called for service at Green Chevy in Peoria, IL I was able to shut the vehicle off and restart it and all error codes were gone. I spoke with the dealer and took it to them. They advised it was a module issue and would reprogram it. It took 2 days and my vehicle is back.

DEF System will count miles down saying it is going to put you into limp mode while towing, when there is 3/4 plus DEF fluid in the tank. This caused me several times speed slow downs under 65 to try to make it to a safe place to add under 2 gallons to fill a 5 plus gallon tank on 70 to 80 mph highways a few times at dusk and night with limited off off travel lane access! This is telling you it will put your vehicle in limp mode! Again causing a dangerous situation! I very much feared for my well-being along a dark road with cars going 70 plus while I was trying to add DEF to a 3/4 full tank only taking around 2 gallons!!

There is no sound from the entertainment system, this happens randomly about once a week. The Safty concern is that when this happens there is no sound for anything including directionals, other warnings and this can cause a Safty issue. The only way to have the system work again is to shut the vehicle off for ten minutes and restart. My vehicle has had the software updated at the dealership about every three months since I purchased it, and to no avail.

Confirmation of Problem: The issue was confirmed by a certified GM dealership technician, who diagnosed the failure of the #6 lifter. They advised that the lifter and potentially the camshaft need replacement. Inspection: The vehicle has been inspected by the dealership service department. No inspection has been conducted by police or insurance at this time. Warning Signs: Prior to failure, there were no warning lamps. However, the vehicle began exhibiting a noticeable ticking noise followed by rough idling and reduced performance approximately 71,000 miles.

We took our vehicle to Weber Chevrolet in Granite City, Il on June 26 for an oil change. My husband and I purchased the vehicle on [XXX] from this dealership. We asked if they could put a heavier oil in the vehicle due to this being as one of the remedial fixes for the recall. The service department manager informed us that they would not be able to do this due to it voiding our warranty. They could not give a general answer as to when they will address the recall. My husband and I have safety concerns about taking this vehicle cross country for a family vacation at the end of July. We have decided to trade the vehicle in for a different model due to the uncertainty of the recall. Appallingly, no dealership, including the Chevy dealership we bought it from , is willing to take our 9 month old truck as a trade. We were informed by three separate dealerships that the car is basically worthless and they are not willing to have it sit on their lots depreciating until the recall is complete. It is completely unacceptable that we, as consumers, are stuck with a vehicle that has a potential safety risk. The car has already depreciated by $10,000 according to Kelly Blue Book. We have filed a complaint with the BBB, Illinois States Attorney Office, and with General Motors. General Motors informed me on July 2 that they will not address the recall until an issue occurs. If an issue occurs then they will address it at that time. Furthermore , they are not willing to buy the vehicle back, attempt to see if the engine is fine, nor willing to allow us to trade for another GMC vehicle. We are at a loss as far as our safety, loss of investment, and lack of any help from General Motors.

6.2 L engine around 7500 miles engine light came on, it was slow to startup, would shutter during idel. Driving home on the highway the truck turned off cruise control and front impact warning then it came back on about 5 miles down the road. At the same time the truck was shaking and shuttering. Took it into the shop the next day and so far is having at least one maybe 2 cylinders misfiring. Also, since I bought it the axle locks keep saying to service them, take the truck to the dealership and they can't find anything wrong with them. The only way to get the indicator to stop dinging incessantly is to active the axle locks and deactivate them and that will make it stop dinging for about a week.

Valve body needs to be replaced. The truck is still under warranty. I have taken it to the dealership, they ordered the part and told me it was safe to drive in limp mode. I've since been waiting a month for the part to come in without a replacement vehicle. I can't drive to work and am losing quite a bit of business. There is a valve body in stock 97 miles away and GM will not ship it to my local dealer or help me in any way. The truck will not make it 97 miles for the repair. The check engine light stays on for a few days and goes off. I can only drive about 10 miles before it goes into limp mode and the dash will tell me I have reduced acceleration and to drive safely. As far as the safety of me and others UNKNOWN. The dealer has confirmed there is an issue but insists I continue to drive it even though I'm damaging the transmission.

I purchased the Curt Triflex Next Trailer Brake Controller GM Part # 19435732 ( Although may be sold through several part #s) from Jim Norton Chevrolet as this is a GM recommended part through the GM parts catalog and is plug and play with included wiring harness making simple no wire splicing connection. The brake controller we need to tow or travel trailer it worked great for about a month maybe two , then I went to hook up our trailer and the brake controller would not function. So I had a electrician trouble shoot the power and all that checked out good. I contacted CURT for a warranty claim and they stated this is a known issue and they are sending me a new one and I did respond that's spooky what if I was towing and it stops controlling. this could lead to a serious safety issue. I unplugged and it and plugged back in and it started working then stopped again before the next weekend to pull my trailer. again Curt stated via email this is a known issue and sending me a new one when they are in stock , but I had not heard this until I contacted them for warranty claim and still have not received a replacement.

On 7 or 8 occasions while navigating parking lots/driveway turnaround, i bumped the resume switch on the steering wheel and the truck took off accelerating rapidly from 2-4 mph speed until I disengaged with the brake. Someone with slower reactions or unaware of what is going on is going to get hurt by this. I believe it's tied to collision avoidance system and the adaptive cruise control mode. This system will allow cruise to stay engaged even as it slows you to a halt in, e.g. a rush hour slowdown, but if it slows you to some speed just greater than zero, and the traffic ahead speeds up, it will speed back up to the cruise setting. Similarly, when cruise is disengaged by brake action, but there is still a stored value in cruise control, if you accidentally hit resume at slow speeds the logic is treating it like a traffic situation. So the old 20 or 25mph minimum engagement speed no longer applies. As for why I inadvertently hit resume, it has to do with the raised momentary rocker switch at the 9 oclock position on the steering wheel. If you make a turn with your palm against steering wheel. For example, on a left turn, if the wheel is turning counterclockwise and your left palm is in the 9 o'clock position, it can rub against the raised cruise control rocker triggering the resume function, and off she will go! A flush or recessed button/switch would have been a better choice here. At this point, a software change would be the best solution to ignore the resume function below a certain speed.

New police vehicle on the road for only two months with only 6030 miles on it. Check engine light came on vehicle lost all power, no reverse, transmission would not shift.

My Silverado has what seems to be a known issue with recent model Silverados which is a broken/blown valve body at the transmission. The week of the failure, my truck began having rough shifting from first to second gear first thing in the morning, but would be fine after that. Two days later this progressed to all of the gears and nearly stranded me and my kids on the interstate due to not being able to maintain speed. I got the truck to the dealership where they looked up diagnosis code and told me it was the valve body and it would require replacing. Unfortunately, the part is on national backorder with unknown delivery time. Looking online, it seems this is a known issue and parts seems to be months (6+) behind. I am stuck paying for a rental car that GM says I will get reimbursed for, but we will see. To complete the questions above, I did not notice any warning lights or notices until it failed.

When in Normal Drive mode, an unexpected or accidental bump of the Transmission T-Handle shifter between the seats towards rear of vehicle while at a stop sign or parking lot, etc. will "Lock The Transmission in Low Gear 1 out of 10 available gears". If one pulls out into traffic without noticing this event, the engine will approach redline without shifting into the next gear until the situation is acknowledged and the T-Handle is one again pulled back to reset it into automatic drive mode. This is frustrating and potentially dangerous if the situation is not recognized quickly. I suppose engine damage could be at risk. There is "No save the engine by automatically selecting the next gear if this condition happens. There is also no lockout requiring the T-Handle Shift Button on the side requiring to be pushed to acknowledge the desire to set this mode". I tested similar settings on Honda Pilot and it DOES UPSHIFT even if in this manual mode to protect engine and occupants from this difficult situation. I personally will no longer allow any others to drive my truck until this situation is remedied. It appears to be dangerous to me and my truck for those who have no idea this can occur. Please try it for yourself. Vehicle must be similar to 2024 Silverado High Country w T-Handle shifter between the seats. My hope is an over the air update can remedy this situation.

I was driving on the highway passing an 18-wheeler, my truck started making a noice. I hit my hazards and heard others hitting their brakes as I moved for the shoulder. My engine failed and my truck is at the dealership waiting for a new motor and radiator. No warning lamps or messages.

Pulled into parking lot and went into a store. Upon leaving I noticed the vehicle would not back up when placed into reverse gear. The engine would rev but, no movement. I pushed the vehicle backwards and then restarted it. The vehicle would move forward. I stopped and attempted to try the reverse gear a few more times with no luck. As I started driving on the main roadway toward the GM dealership, the vehicle upshifted once and then displayed a warning along with e check engine light. Once at the dealership, they scanned the vehicle and confirmed a transmission issue. The vehicle never showed any symptoms prior to the failure.

The engine failed and had catastrophic damage. As I was driving it on the highway at speeds of 65 mph the vehicle started loosing power and shaking violently in the middle of driving it. Therefore putting my life and other life’s in danger. After a couple miles the Electronic stability control light came on and the traction control light came on. Also the check engine light came on. Vehicle only has 7500 miles and was driven daily without any mistreatment. The dealer confirmed that the vehicle had catastrophic damage. It had metal shavings inside the oil system. The dealer confirmed the next day that it was worse than when I took it in and they weren’t even able to move it to the engine bay.

While driving in traffic, car was making weird shifts and strange noises. The engine suddenly lost all power. I tried to restart and the car wouldn't turn over. I tried again and it finally turned over after struggling.

I was going 70 in the fast lane on [XXX] near birmingham, Al; when my 2024 Silverado lost propulsion, electrical and power steering. I was forced to move 3 lanes over to the emergency lane or wreck off to the left. When it lost propulsion i lost turn signals and power steering. They are going to attempt to fix it, but engines are on backorder. Regardless if it is fixed, the thing almost killed me. There's no way I'm going to be driving that thing. This issue was confirmed at the dealership and no warning lights came up on the screen prior to losing propulsion.

Vehicle has 19299 miles and engine started rattling on deceleration and making clicking and knocking noises. Engine simply stopped working on the highway on the way to Chevy Maintenance. Couldn’t even shift to neutral to get it on the tow truck. It had to be dragged up the ramp. The the clicking and knocking to engine failure happened in one day. Now my truck is sitting in Chevrolet waiting on an engine which is on back order. So I’ll be without a truck that I’m making 1800/mo payments on (took 36 month loan) and can’t even reduce my insurance to comprehensive due to being at a maintenance lot. Bottom line, I have a new undriveable truck with no date available as to when I’ll even get it back. It’s been suggested one to two months…

My 2024 Chevy Silverado Trailboss with the 6.2 engine has had engine tick since it had about 1200 miles on it, I brought it into the dealer where I purchased it and they determined nothing was wrong with it, now today, the noise is way worse, so I called local dealership to my area, with this engine recall on the 6.2’s, the service guy I spoke with said GM has not come up with a remedy yet so there is nothing they can do about it. I asked them what I’m supposed to do, he said keep driving it until it locks up, I asked him if he was serious and he said yes, drive it until it locks up then have it towed to dealership, if they have a loaner I might get one, I said it’s a safety issue if it locks up on the highway or in traffic, he said yep, drive it until it locks up! GM has had 2 buy back programs on this and they still do not have a fix?

On April 25, 2025, I was driving on the expressway to work when my 2024 Chevy Silverado 6.2 liter suddenly lost all power. I had to coast from the 3rd lane to the off ramp to get out of other vehicles. My truck was towed to Garber Chererolet in Webster NY, at an expense to me. On April 28, 2025, I was informed by the service manager at Gar er Chevrolet that my Chevy Silverado, 6.2 liter motor blew up and needed a new motor. Later on during the course of that day on April 28, 2025, I learned of, on a national media platform, that General Motors initiated a recall for the 6.2 liter motors that were defective not only for Chevrolet products but all GM products with the 6.2 liter motor in them. Unfortunately I never received a recall notice by the Chevy app, email, USPS Mail or any other means of communication. On Tuesday April 29, 2025, I initiated a claim with General Motors Customer Service Care. This is very very bad, knowingly that there were issues for years with the 6.2 liter motor. I've driven Chevrolet my whole entire adult life because I believe in the product. However, I am going to reconsider my buying options immediately due to the incompetence and negligence of General Motors. This is a serious offense, not only against me but for the whole general population that drive these vehicles. GM pute and all in a very serious situation that could have led to serious physical injury or death itself! Now General Motors tells me that I have to wait between 2 and 3 months for a new 6.2 liter motor because it's on back order. This is not acceptable in no way for myself or anyone else. I will be joining the class action lawsuit against General Motors and all the incompetent executives who knowingly and egregiously hid this from the general public, their customers, including myself. I am beyond angry and have zero confidence in GM going forward.

Since purchasing this truck 06/30/2024; during the 9100 miles driven, electrical issues such as check engine, EWS needs to be serviced, Forward Collision Service, Stereo screen freezing up, Tire Pressure stating air is needed but checked air pressure, it is where it should be, Right Signal Trailer service needed but not pulling a trailer. Three times after starting the truck it failed to go into reverse, stuck in neutral. Two of the three times it was able to reset after 10 minutes of shutting down the truck and restarting. Third time had to get the truck towed due to unable to reverse out of parking spot. When driving it seems as if the truck is stuck in 2nd gear while trying to accelerate, rough driving at times. When car turns off it makes knocking noise and sounds like it is trying to turn off electrically. Tailgate would open while driving even though shut and checked. Driver seat motor failing while trying to move the seat. Middle seat stays in upright locked position for days before it will release. Dealership is stating that valve body needs to be changed but will take up to 6-8 months due to backordered part, but no loaner car is available. Will have to be without a vehicle for the entire time. All is covered under warranty.

I got my new 2024 Chevy Silverado 2.7l turbomax custom 6 months ago. It shifts weird the first few times from a cold start. I have asked the salesman and he said yeah you have to let the truck warm up for 5 min or so. But even in doing so it still happens, worse the colder out it is. Yesterday I went to grab some food and went to take off onto the main road and when it tried to shift from first to second it felt like the transmission just stopped working for a few seconds then hit 2nd gear hard. I was told this was because the truck needs to get used to the way I drive it. Which I now have close to 4,000 miles on it and it still happens almost every time I shut the truck off and it cools down to ambient temperature. I know this is not normal, and a big safety concern because when I do go to pull out and this happens it feels like a total loss of power and does not take off like it should. I have yet to bring it into the dealership. But I have called about the issue and was told this is normal and would go away. Which it has not. So I am going to make a appointment to get it in the shop. I have also read that many others are having this same exact issue. In which case some people are saying they told them the same thing “that it’s normal”, I have heard others say they will change transmission fluid because the fluid they used is to thick, and have heard of others who had to have them change out the control module for the transmission and or reset it. I am just worried that I’m going to pull out on day and have this happen and get hit from the rear because I don’t have the power I should have to take off properly. Not to mention I should not have to let my car idle for 5-10 min before I can drive it. That’s a huge waste of gas, and time, plus having your direct injection idle makes a ton of carbon build up in the engine. I am not a certified technician but I have been working on my own vehicles for over 20 years now. So a brand new truck should not be doing this.

It happened to me twice but the first time I was driving on the highway with my family and without warning my engine cut off and I had a message that said “press start button to restart”. I coasted to the shoulder, put the truck in park, and was able to restart. I took it to my dealership where they ran codes and nothing wrong with the engine showed. About 2 weeks later I was taking my kids to daycare and had just exited the highway when my engine cut out again. I pulled up to the 4 way stop sign intersection and tried to restart the truck but it was completely dead and I was stranded in the middle of the intersection with my 3 and 1 year old. The truck threw an engine light this time. I tried to get the truck out of the intersection but the gear was stuck in park and wouldn’t shift to neutral. I then had the truck towed to my dealership where it has been since.

While merging onto the fast lane of the highway i experienced a "press push start to restart" alarm and total loss of power as I went to accelerate and merge with traffic. It was almost like the truck was in neutral but pedal would not even increase the rmp. There was no shoulder and I was forced to stop and restart my vehicle between the onramp and the fast lane. Im fortunate to not have ended up in a bad rear end accident. It did the same a half mile later where atleast I had a shoulder to pull off onto this time. Check engine light threw up a camshaft position sensor fault

While driving on March 23, 2025, we heard a loud bang, we stopped at a gas station shortly thereafter and realized the tailgate had fallen open while driving and struck the trailer hitch. The latch/camera compartment were broken and hanging from where it struck the crank for trailer hitch and the tailgate was damaged (dented). It was taken to the dealership where they advised there is a recall on some models due to this same issue. They checked and advised our truck is not part of recall. We filed a PAC claim with Chevrolet which they are declining to pay. The latch/camera is currently taped into place. It has fallen open while driving one additional time since the first event. We frequently carry things in the bed of truck and our safety and that of anyone behind us could be in jeopardy.

The 2024 silverado with 13.4 infotainment system is unpredictable and often looses paring with iphone during driving. This is a major distraction because then to reestablish pairing for directions from apple maps or google maps chevy tells me you need to stop your vehicle. Put it in park. Re-establish pairing, te-enter destination and have it car play. This is 10x more distracting that someone using their phone non hands free. Furthermore gor music it often defaults to sirrus radio and to get itvto am or fm tequires you to step through many buttons on the steering wheel or touch an extremely small button like 3/16” in diameter to change to either am or fm. Again, a huge distraction. My 2016 chevy cruz and 2017 silverado worked flawlessly with out distraction. I talk to many others who have simply given up on using it because its too dangerous to take your eyes off the road to change settings. Im a retires EE and software developer and this is terrible and NTHB should look into it and test drive one for a couple hundred miles. Been buying Chevys since my first car in 1976 and never been disappointed with any till now. GM customer Service on several occasions and local dealer has been no help

I had a engine failure in my 2024 Chevy Silverrado Trail Boss1500. I had just exited off the highway and came to a complete stop at the stoplight. When the light turned green, I hit the gas pedal and I did not move. I looked down at my gear shifter and noticed the truck was in park (I did not shift the truck into park). I tried to put the truck into drive and realized the engine was not running. I tried starting the truck and it would not start. The truck would crank, but would not start up. I tried this several times with no luck getting truck started. I even tried to put the truck in neutral to get the truck out of the middle of the road and could not get it neutral to move it. I called chevy roadside to tow it to the dealer. The dealership called me on tuesday and said the engine had blown because of a bearing failure and engine needs replaced. Also, they have not let me know approx time I will get my truck back. They claim there's a shortages of engines on the 6.2 liter engine.

Truck has 7000 miles defective valve body failure would not go into reverse and in limp went to dealership and diagnosis is needs valve body replacement with parts on back order with no eta. They said it could be 3-5 months. This is a national issue I’m on multiple social media sites for Chevy trail boss and there is too many to count and it’s been happening since 2021. GM has been no help no loaners and you have to pay for a rental for 3-5 months and pay your truck payments and hopes you are reimbursed at the end. They just recalled the 2021-2022 same 10spd transmissions they are selling Trucks knowing these issues exist also the lifter issues with total engine failures at 10000 miles. The transmission lock up at high speeds.

the transmission slips into neutral when in drive or reverse. yes dealer states it the valve body on transmission part not available called general motors and they state looking to get part can not tell us how long this is on a brand new chevy silverrado 4WD 2024.

The truck suddenly and completely shut down while I was driving on the highway, with no warning signs before the total power loss. This unexpected failure put me in a dangerous situation. The vehicle had to be towed to the dealership where it was purchased, and after inspection, the dealer informed me that the engine had completely failed and now requires a full replacement.

While driving my vehicle on the highway I was exiting when I looked down at the instrument panel it stated a message along the lines of shifting to neutral and to press the ignition to restart engine. I noticed the vehicle wasn’t accelerating when attempting so I slowed down and did what it instructed me to do. The engine then wouldn’t start, I was uneasy because cars were coming from behind at a decent speed because of morning traffic. I somehow managed to get it to crank and took it to the dealer right away. They stated it was from low voltage and were replacing the battery under warranty. I didn’t think that was the cause but gave them the benefit of the doubt. 2 weeks later while taking my family out, the same incident happened. I wasn’t able to get it to crank and had to get it towed to the dealer. They stated it was the engine because now the engine was making a loud sound when ignited. It is about to be 4 weeks without vehicle and no repair has been made due to no inventory on engines.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving 65 MPH and hauling a trailer, the "DEF Empty, Refill Now" message displayed, while the Diesel Exhaust Fluid (DEF) system was full. The failure reduced the power and speed. The vehicle was taken to the dealer and a second dealer, Young GMC of Burley (325 Overland Ave, Burley, ID 83318), where it was determined that the Diesel Exhaust Fluid (DEF) system would not function properly while hauling a trailer.

Was pulling out onto the road from sitting at a traffic light, vehicle was going less than 25mph when the engine made a clunk trying to shift and the check engine light came on. Computer software indicated “limp mode with reduced acceleration activated.” Vehicle wouldn’t accelerate above 35mph, had to drive on major highway to get to dealership. Truck is only used as commuter vehicle hasn’t towed anything. Dealership indicated valve body transmission failed with vehicle only have 9k miles on it. Part is on back order as it is being manufactured due to installed faulty part, problem has been going on in 2023/2024 Chevy and gmc trucks since January 2024 without a recall put in place. Problem is being fixed after the part fails and the truck fails to run at optimal valves. According to forums software update were installed versus recalls to the actually valve body part being. I was sold a truck in sept 2024 with a faulty installed part versus it being fixed before it was purchased. This caused me to be stranded 1500 miles away from my home and we were not made aware of the know valve body transmission issue. The information was covered up versus being disclosed.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving 55 MPH on a highway entrance ramp, the vehicle failed to accelerate upon depression of the accelerator pedal. The contact stated that the "Reduce Acceleration Drive with Care" message was displayed on the instrument panel.

Once the contact arrived at the dealer, 13 diagnostic trouble codes were retrieved; however, the dealer could not duplicate the failure. An appointment was scheduled with the same dealer, and it was discovered that the diesel particulate filter was clogged with soot, causing the vehicle to enter LIMP Mode. Despite this discovery, the dealer was unable to duplicate the failure after the filter was unclogged. The vehicle resumed normal operation. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was 11,267.

Experienced sudden engine failure while driving on the interstate. Mileage on the vehicle is 11,635. Engine has been maintained as per manufacturers recommendations. Currently at dealership awaiting engine replacement. Was informed that main locking cap for crankshaft came apart, resulting in a hole in the engine block with sudden loss of oil and oil pressure. Currently replacement engines are not available as GM has had a large number of 6.2 L engines that have similarly failed. Dealer cannot provide information on when replacement will be available.

Truck went into second gear unexpectedly at 50 mph due to what dealer said was a bad solenoid. GM has had the truck for over a month with no date of an times repair due to no parts being available

I’ve had 3 occasions of this brand new vehicles front collision avoidance system going off HARD and locking up the brakes. It scared the crap out of me as there was nothing in front of me - if I hadn’t known the truck had automatic collision software - I’d have driven to the Chevy Dealership right then. The first time I thought it was a fluke. The second time it really caught me off guard. The third time (inside 2 months) I realized there is something not right. I reported it to the dealership but they wanted me to trade it in for a new truck. Sorry, no. I just want to report this problem as I’ve seen a recall on other vehicles with 10 speed transmissions. Their shifting problem - is also present in the Chevy Silverado Truck - but it has not impacted my use of….

While driving on the interstate at 75 MPH, the vehicle lost all motive power. No warning light was illuminated. I pulled over to the right side of the road and attempted to restart the vehicle; however, the vehicle failed to respond as needed. It was -30 degrees outside and it was dark. I had passengers in my vehicle, and we were stuck with no power or heat on the interstate. The vehicle could not be put into neutral to be moved off the interstate because there was the vehicle would not turn on. This was an extremely unsafe and dangerous situation for me and my passengers. The vehicle was towed to the dealer where it was diagnosed and determined that the engine was damaged and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and the contact was informed that the engine was not available for replacement. The vehicle is still at the dealership and has been there for 2 months. The approximate failure mileage was approx. 19,000 miles.

On [XXX] at [XXX] while driving at highway speeds (70-75 mph) on [XXX] , I experienced engine failure in my 2024 chevy silerado zr2. Within seconds, the truck began to lose engine power, the check engine light came on, a transmission warning displayed, the truck shook violently and lost electrical power and power steering. I was able to get to the shoulder in less than a minute and the truck shut down completely. After exiting the truck, I observed smoke, the smell of fire and engine oil/ fluids all over the ground. There were no warning lights or symptoms prior to the engine failing. The sudden loss of power and power steering could have resulted in an accident. The vehicle has been inspected by a certified chevy dealer and they have verbally confirmed engine failure. i have not been provided any documentation or formal updates on the process.

My name is [XXX] and I currently own a 2024 Chevy Silverado 1500 ZR2 Truck with a 6.2 lt motor. On [XXX], my truck failed me at which point it had to be towed by road side assistance to Sun Chevy in Chittenango NY. While at the dealer I was advised that my Truck engine 6.2 is bad that the crank shaft bearing failed and further piston rods failed and it would need to be replaced. Two days following I received a call and was advised by the dealer (Sun Chevy) that GM advised the dealer to rebuild the engine. Once that was completed 10 days later the dealer contacted me and stated that the motor does not sound right and there were further problems. I was also advised by the dealer that this is a known problem with 6.2 motors and GM is aware of it. On (3-14-2025) I was told by Sun Chevy that the 6.2 motors are on backorder and I would have to wait approx 6 to 9 months. This truck is not even 1 year old and this is not acceptable in any way. I am paying on a truck that is not operable. I have always been a faithful Chevy owner however I cannot wait this long after buying a New Truck. I called GM to discuss options moving forward and them replacing my Truck. I can be contacted at [XXX], or [XXX]. According to GM This issue has been assigned a case number and that as far as it has gone. My famiky vacation now has to be cancelled as we were going to be traveling in the Truck and the Dealer stated that the loaner vehicle cannot leave the state. This is a complete mess.

I was driving on [XXX] leaving from Onawa, IA. Up to this point I had not issue or notifications about my vehicle. While driving North bout and having the adaptive cruise control set at 80 MPH, I was in the left lane passing 3 semis in the right lane. After passing the first one, the first semi merged to the left lane following. I was approximately 1/2 passed the next semi when all the sudden my cruise started to slow down. It went from 80 to 78 back to 80, then 80 back to 77 to 80. Suddenly and with no warning the engine completely shut down and I went from 80 - 0 is approx. 100 feet. The semi behind me sounded their horn loudly as they almost hit my rear end before merging over. I had no time to go over to the right shoulder and had to go to the left where the vehicle would not move. I could not move the vehicle off the shoulder as it would not shift to natural. Law enforcement was notified as the safety of the vehicle on the left side of the interstate caused safety issues.

Dear National Highway Traffic Safety Administration, I am writing to formally report a serious safety issue with my 2024 GMC Sierra 1500 equipped with the 6.2-liter engine. At the time of the incident, my truck had only 17,000 miles on it and had received the two necessary oil changes as recommended. On Thursday, [XXX] while driving northbound on [XXX] in Houston, Texas, my truck unexpectedly lost power while in motion. Fortunately, I was in one of the right lanes and was able to push it to the side, but not before nearly being struck by another vehicle. Several cars had to swerve to avoid my disabled truck, and I truly believe that I could have been seriously injured or worse due to this mechanical failure. After having my truck towed to the dealership, I was informed that the engine had completely locked up and needed a full replacement. However, despite my immediate action to get the issue resolved, I have now been without a vehicle since [XXX], and as of today, March 10, 2025, there is still no replacement engine available. I have been told that the 6.2-liter engines are on backorder for 5 to 6 months because this issue is happening to so many vehicles. This raises serious concerns: If so many of these engines are failing, why has there been no recall issued? How is it acceptable for GMC to sell vehicles with a known defect that can lead to life-threatening situations on the road? Why am I still paying a $1,300 monthly car note for a vehicle I have not been able to drive in over three months? This is not just a case of vehicle reliability; this is a severe safety hazard. My truck failed suddenly in moving traffic, and based on the widespread engine failures, it appears that this could happen to many other drivers as well, potentially leading to catastrophic accidents. I urge the NHTSA to investigate these engine failures immediately and take appropriate action, including issuing a recall if warranted. I would appreciate an update on INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Motor blew in my 2024 Chevy Silverado. Motor was a 6.2 liter, L87 with 17,600 miles. Tomorrow will be 4 weeks without my vehicle. I've gotten no information on when any repairs will be made, nor have I gotten any support from the dealership or GM. I was driving 60+ mph in heavy traffic when the motor went. I was put in a bad situation and was lucky to get out of it without injury. I don't know what to do and need help!

Reduce Acceleration drive with care and engine light came on. Can’t go faster than 40 MPH and unable to reverse. Only 8,000 plus miles. According to mechanic, it’s a sticky transmission valve and there should be a recall.

I believe the GM 13.4 infotainment system, particularly the navigation system and the radio control exhibit a very bad driver distraction that could lead to wrecks. Specifically with much more traffic now a vast majority of people traveling beyond places they are familiar with rely on the bigger screens on new vehicles so they get a clearer picture of turns ahead. I have experienced multiple occasions where the Silverado infotainment/navigation system randomly unpairs itself from my iPhone and then I’m forced to handhold a phone for navigation which is illegal in my state. I’ve talked to others that have the same problem, the screen going blank and it unpairs whether wireless Bluetooth or USB connected to the proper port. Unacceptable for a $70,000 vehicle. Also GM apparently in an attempt to advertise Sirius radio and subscription plans displays what appear to be warning signs on the display thereby distracting a driver again. The only way to change out of the Sirrus default stations reliably is to push a very small software button smaller than a pencil eraser. Again you must take your eyes off the road for a couple seconds to perfectly align your finger with the active portion of the software button. I see no way to say default to say radio on startup. You can on the steering wheel toggle many pushes to get through factory presets but many of those presets take you back to the menus to order sirrus radio. My background is electrical engineering and IT systems. I’ve never seen a more complicated and unreliable sequences and I don’t believe GM fully tested it. There is no doubt in my mind it’s a serious distraction more so than just about any other distraction because it’s particularly annoying and then puts the driver in a bad mood. I understand Android phones work slightly better but the population of Apple phones is significant. I’ve spoken with GM customer service several times and Apple several times GM blames Apple Apple blames GM and Google/Android head unit

The entire camera safety system is glitchy. Whether backing up or not, the side, front, back and top view camera system intermittently works then doesn’t, going days on end without working.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that upon starting the vehicle and shifting into drive(D) or reverse(R), the vehicle failed to respond. There was no warning light illuminated. The vehicle was towed to the dealer, where it was diagnosed that a transmission valve needed to be replaced; however, the part was not available. The contact continued to drive the vehicle. The contact stated that the failure recurred. Additionally, the contact stated while her son was driving at an undisclosed speed and was accelerating, the accelerator pedal traveled down and remained stuck, causing the vehicle to accelerate unintendedly to 50 MPH. The brake pedal was depressed but failed to respond. A message advising to decelerate and to drive safely was displayed. The vehicle jerked while downshifting to low gear. The contact's son shifted to neutral(N), and the accelerator pedal was no longer stuck. The contact's son was able to pull over to the side of the road. The contact's son resumed driving; however, the failure recurred while driving. The contact's son was able to drive to the residence. The vehicle was towed to the dealer, where the transmission valve, six seals, bolts, and unknown parts were replaced. The vehicle was repaired; however, the contact stated that she did not feel safe driving the vehicle. The contact was in the process of trading in the vehicle. The manufacturer was notified of the failure and covered the repair under warranty. The failure mileage was 6,893.

My truck had a check engine light come on for the transmission 2 months ago and then it went off before it was serviced. They said they couldn’t do anything since the light went off. Then last week I didn’t have reverse and it wouldn’t shift into gear. A week after it had been in the shop they told me the transmission valve body needs to be replaced. Expected date for parts to arrive is 3-10.

Hi - I'm filing a complaint against Chevrolet with the NHTSA's Office of Defects Investigation. I purchased a brand new 2024 Chevrolet Silverado in Dec of 2024 from a dealership in MA. I've had the truck for only 2 months and only a couple thousand miles. I was in Quebec with my family for a ski vacation and we were driving back on [XXX} when my truck suddenly started making loud engine noises. I was able to get off the interstate to a gas station and then the truck turned off and would not start again. I had the truck towed to a Chevrolet dealership in Granby, Quebec. There was no warning or alerts before the engine failed. This is a known issue that the NHTSA is currently investigating, it has to do with the 6.2L V8 engine in GM vehicles from 2019-2024. The engine is seized and cannot be repaired, truck needs a new engine. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Valve Body failure at 5,500 miles. Transmission wouldn't engage in reverse. Truck went into limp mode with a reduce speed message. Valve Body is on back order for 7-8 months. The dealership decided to order a new transmission. Ive been waiting almost two months for the transmission to arrive.

Total engine failure on interstate in North Carolina

Date of purchase [XXX]. Date of incident [XXX]. I was on my way to work at [XXX] and it was raining . Truck would not accelerate more than 45 miles an hour speed limit is 65 on the freeway. Engine light turned on and all the dashboard icons turned on. Drove it to the nearest dealership Tom Bell Chevrolet in Redlands Ca. Once I put vehicle in park it would not start. The message on the dashboard board displayed something like unable to access. So I went to see if service center open since it was [XXX]. He instructed me to drive around I said it will be not go into motion. After 15 minutes I checked the status on my phone and it did not display anything wrong so I went ahead and turned it on and drove it to the service center but once again it would not accelerate and shock vigorously. Once in the service line it turned off and did not stay on. Dealership ran diagnostics he mentioned cylinder and piston but they need to run more test. He called me back 2/14/25 asked if I had taken it to the dealership where I bought since purchased I said no it’s brand new, it looks tampered with . Called me back again and said this vehicle had a motor recall and a technician at Riverside Chevy worked on it and all the components are not connected we can work on it it need to go back to them and they need to explain what is wrong. He sent them a video of the tech looking at everything that was wrong. Truck was towed to Riverside Chevrolet [XXX]. This is a brand new vehicle that only had 17 miles when purchased by me ,at the moment it has 709 miles non of the components of this vehicle are new anymore they are either melted or rattling inside ,the gas tank sounded like empty cans rolling around, the transmission would not make the vehicle move. It is called lean mode if I’m being correct the vehicle was protecting it self from what I don’t know, so yes I feel it is unsafe and would like your help with this vehicle matter at your earliest possible conve INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2024 Chevrolet Silverado 1500 Trail Boss While driving, I was given no notice to the vehicle shutting down, couldn't go forward nor backwards. Barely got off the road, waited hours on rollback. Dealership ran a test, said "control valve body " problem. Part is ordered, on back order. GM - taking software to attempt to monitor when? this problem is going to occur? They know about excessive wear, Why not Re-Engingeer this problem instead of selling vehicles that no one knows when this problem of stopping on the road will occur. That would be a safety issue. A hazardous issue of driving on the road and not know when this would happen. If the vehicle doesn't stop from GM software, the rear wheel brakes lock up.

Less than 9,000 miles on a 2024 Silverado Trailboss and the Transmission goes out. Truck goes into limp mode, which is dangerous if you are on a highway. The new truck has been sitting at a Chevy dealership for 3 months waiting on a replacement part (valve). Have an incident number with GM, and they are pleasant on the phone, but they never call back with information when they say they will.

TRANSMISSION VALVE BODY No warning. Was working fine and all of a sudden shuddered and downshifted and the lights lit up. vehicle has been at dealership for 50 days now with no ETA on this part. This is a national known problem and the recall has not yet expanded to the 2024 model.

There is an electrical problem in this vehicle. You can be driving down the road with your high beams on, and they will start flashing. Or they will stop working altogether. Dashboard lights will go out until a restart of the vehicle. ( Speedometer or Tachometer.) The overhead light can just come on driving without you having touched it. The steering wheel controls will stop working. Until you restart the vehicle. The radio has gone out until restart. I have already had to have the transmission replaced in this truck at 24,000 miles. The dealership keeps telling me about these new issues. That unless they find a code. There isn’t a problem. This is not what I paid 62,000 dollars for. The dealer I bought it from is telling me that they will possibly do a buyback. Yet they keep telling me they will get back to me and they don’t. I called the woman who was supposed to call me back. She says she had a family emergency. Chevrolet needs to back their vehicles.

The valve body in my transmission went out in Colorado where my truck is currently at a dealership under warranty. They are putting my job at risk due to the fact that I bought that truck specifically for work since I travel all over the country for work. I told them that I need the part expedited because I need to leave Colorado and go to Texas for work on the 28th and still no help at all. All I’m asking for is for the part or a new transmission to be sent and installed before the month ends. Because if it doesn’t I’ll get fired if I don’t make it to Texas. And I’ll state this I will pay out of my own pocket even though the truck has warranty if it means the part can get expedited.

Driving on interstate 85 on cruise control when I herd the motor RPM start to climb so I tapped the break and that’s when the truck shut itself off and put itself in neutral causing me to have to coast over to shoulder of the road. Message on the dash said push start button to start again. There were no check engine lights, no overheating temperature lights. No codes at all. The truck is a 2024 with 62,000 miles and all oil changes on time. Upon checking online , this has happened to other vehicle owners as well. Apparently the Chevy Silverado with the 6.2 liter engine has problems with push rods and bearings. Some have replaced multiple engines. Chevy wants me to pay for new engine.

the digital speedometer disappears randomly as do other visual features of the driver information area the trucks auto lock feature randomly docent lock the truck or unlocks the truck when unattended

Engine check light came on at 10,500 miles and under 300 hours of engine time. Initially thought it was due to a wheel speed sensor failure from the salt and brine build up from winter weather. After having the code ran the engine is misfiring and has a rough idle. This is an L87 6.2L motor on a 2024 Silverado ZR2. After researching this problem it is way more frequent than the total of 39 official reports with a similar truck owned by an acquaintance having the same issue at the same mileage. Engine sound has changed, the truck shudders, and may seize up at any moment. The truck had 1 oil change at 5500 miles and was due for its second oil change at 11500 but will more than likely need an engine replacement.

Shortly after I bought this truck, At about 3,000miles I thought it had an exhaust leak, I took it in to Chevy and they kept it for a few days. Well they get back to me and said that the lifters had failed. They put new ones in and these too failed. Then about 2 weeks later they got back to me saying they were waiting on putting a new motor in for the truck. This is the 6.2L that is known for lifter failure. After about 2 more weeks they reached back out and had said that the truck was almost done. When I got the call to come get it, I asked when I got there what do I do when this keeps happening in the future of me owning the truck. The service guy shrugged his shoulders and said “buy and extended warranty.” He then proceeded to tell me to buy a chip that will delete the DFM in the truck but will void my factory warranty. I’m very frustrated and worried for myself in the future with this truck. I’ve already spent so much buying the truck and in a few years when my warranty expires and this happens again that will be out of my pocket.

Vehicle with out warring lost significant portion of its power and was put in reduced acceleration mode. This is a brand new vehicle less than 12,000 miles. The truck was towed to a dealership and the cause is a failure with the transmission valve body. Truck has sat a the dealer unrepaired for 2+ months.

Subject: Engine Failure – 2024 Chevrolet Silverado 1500 (6.2L V8 •VIN: [XXX] Issue Description: While driving on [XXX], I noticed the transmission would downshift but not upshift. Within seconds, a warning appeared: “Oil temperature high, idle engine.” I began merging onto the shoulder, but before I could get there, the engine shut off completely, and the transmission shifted into neutral. After coasting to the shoulder, the transmission shifted into park on its own. Failure to Restart & Electrical Issues: I attempted to restart the engine, but it would not turn over. The dashboard, radio, and electronics turned off for a few seconds before coming back on, but the engine remained unresponsive. Towing Difficulties & Roadside Assistance Failure: GM Roadside Assistance said no contracted towing companies had the equipment to tow my truck because it would not shift into neutral without the engine running. I had to find and pay for a tow truck myself, with no guarantee of reimbursement. Dealer Response & Repair Delays: My truck has been at the dealership for days, but they have not started repairs due to technician shortages and a backlog of work. They stated: •Manually cranking the engine is nearly impossible. •The starter is not strong enough to turn it. •Repairs could take months. Loaner Car & Additional Hardships: Per the GM warranty, I received a loaner car but must return it every 500 miles. Since I commute 160 miles per day, I must frequently exchange it, causing major inconvenience. Safety Concerns & Requested Action: This sudden engine failure on the highway was a significant safety risk. Given that NHTSA is investigating failures of the GM 6.2L V8 (L87), I believe my case is related. GM should issue a recall or extended warranty for affected vehicles.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving at 70 MPH, the vehicle stalled and lost motive power. The contact was unable to restart the vehicle. The contact was driving on a major highway in the fast lane during the failure. The contact was concerned that the failure could have caused a major crash. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 9,000.

This is the 3rd engine failure in 23K miles. The first was a Lifter/Rod problem at around 3K miles. The 2nd was catastrophic engine failure due to a spun bearing at 21K miles. Now at 23K miles, I'm having another catastrophic engine failure with the same issue. Engine is the 6.2L L87.

When Driving my 2024 Chevy Silverado with 24,600 Miles on it this morning, i was on the New York State Thruway going highways speed (70MPH) when the truck Lost Power, and Shut completely off, I had a tractor trailer behind me and lucky my pick up truck was able to coast over the white line, if i would have been able to coast over the white line i would have been in a major accident. I attempted to start the truck up again and the truck would not turn over, i had sat there for about 25/30 Min trying to get the truck started and finally the truck turned over and i was able to continue on to work, While driving the truck had absolutely no power and the truck was sitting around 3K RPMs when going 66mph, the truck was hard shifting into gears as well. I arrived at work and i got to a parking space and all the sudden the truck shut off and wouldn't not start back up. Upon arriving to work i rolled down my window and heard a long banging noise coming from the engine Aswell as a whining noise. I attempted to start the truck up and you hit the start button the truck just keeps whining and never starts up. I was able to contact GM Roadside and have a tow truck come and pick the truck up and bring it back to the dealer. Im awaiting the dealer to contact me. Overall, i could have been in serious car accident for because the engine just shut off on the highway, this happened with no warning or anything, the check engine light was NOT on before this happened.

At 40mph the transmission vibration on the pedal, and at slower speeds.

On 12/24/24 my truck went into limp mode with the notification of “reduced acceleration” nearly causing an accident. Luckily I was able to get off the road to safety. The truck wouldn’t go in reverse or fully accelerate. I had the truck towed to the dealership. The dealership informed me it was the Valve Body in my transmission. They mentioned they have 4 other trucks with the exact same issue. It’s been 1 month since and nothing has been repaired and GM has not responded to my inquiries on a replacement, update on the part, or a buy back. The vehicle was brand new on a lease only 7500 miles on it and was purchased in July. The truck didn’t even last 6months. Had I not quickly gotten the truck off the road I could have been T-Boned and could’ve died at the intersection by a semi coming through. The fact this vehicle was sold, while this was an issue is criminal negligence.

My 2024 ZR2 has roughly 22,000 miles on it. Was driving and lost power. Dealership actually sent someone to come look at my stalled truck. Would not turn over. Dealership got it towed. After diagnosis, they said the engine had seized. This is absolutely uncalled for on a brand new vehicle that I paid over $70,000 for. This exact same thing happened on my Co Workers 2020 high country 6.2. It is currently being worked on, and now seeing that over 877,000 of these 6.2 engines have done this exact same thing since 2019??? How is this engine still being put in these GM vehicles? Now they are going to put new or rebuild the one I have that the exact same thing can happen to the new one? No new warranty will be given as I just get the remaining warranty? I'm sorry but this is the most expensive vehicle I have ever purchased and was proud of it. Now I have a ticking time bomb? I work out of state and if this happened while out of state, what do I do?? I would like action taken! I am getting an attorney involved as this should be taken care of after 877,000 vehicles. What other action can be taken?

The vehicle burns oil and has from the very first oil change. The dealer is stating the oil needs to be changed more often (5k as opposed to 7500 per the manual) to mitigate the fact the vehicle is burning oil. Currently I am hearing lifter tick at cold start and believe the vehicle is on its way to experiencing engine failure of which your organization is already looking into. I am reporting this to help with your investigation. Please feel free to call with any questions. Thank you.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that after the vehicle was serviced at the local dealer for a manufacturer software update the vehicle's display console began to experience failures causing several safety features to become inoperable. Later, while driving in reverse the vehicle crashed into the pole. During the incident, the collision avoidance feature to alert the driver was not activated. The contact indicated that as the vehicle drove closer to the pole the driver's seat did not vibrate, the audible alarm was not active and the warning message was not displayed to alert the driver of an impending crash into the pole. During the crash, the contact experienced an injured back that did not require medical attention at the time. No police report was filed and the vehicle was driven from the scene. The manufacturer and local dealer were notified of the failure but no assistance was offered. The failure mileage was 10,500.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while the transmission was shifting gear, there was a hesitation before properly shifting gear. The contact stated that while stopped at a stop light and then attempting to accelerate while making a left turn at approximately 15 MPH, the accelerator pedal was depressed however, the vehicle failed to accelerate immediately but then suddenly surged forward. The check engine warning light was illuminated, and the vehicle went into LIMP Mode. The contact had restarted the vehicle and drove the vehicle a short distance to the residence. The vehicle was towed to the dealer who diagnosed that the transmission valve had failed, and the valve body needed to be replaced. The vehicle had not been repaired due to the manufacturer taking an extensive amount of time to provide the parts. The manufacturer was made aware of the failure. The failure mileage was 7,485.

I purchased a new 2024 Chevrolet Silverado 1500 4wd in May 2024 from a Chevrolet Dealer in East Tennessee, after having the truck for 5 months, it started experiencing a transmission "shutter / vibration" at higher speeds, it has also experienced a transmission "hard downshift" at times... a month later at only 4914 miles, it was dropped off at the chevrolet dealership here in my home state of Alabama for its first oil change and for them to check what is going on with the transmission, after the truck being there for 3 weeks, we were told that the transmission needed to come out for repairs, we advised the dealership and several GM representatives that we wanted a brand new transmission put in the truck that is brand new to start with, GM has refused and stated that they were going just rebuild the transmission.... we told them "No" and that we had bought a brand new truck, therefore it should have a new transmission, not a rebuilt one in a brand new truck with less than 5000 miles on it.... the truck has been out of our possession starting into its 3rd month being gone for repairs, not only is this a huge inconvenience for us, but its also a huge safety issue because we do occasionally pull trailers with this truck... General Motors has flat refused any help to our satisfaction with this transmission issue and has just pretty just blown us off and told us "No" when we have approached them with any kind of remedies for this situation, its pretty bad when a company that has taken a government bailout a few years ago, hasnt learned anything from their past mistakes and now think theyre untouchable.... it also pretty bad when you spend in excess of $60,000 for a pickup truck that you dont even have in your possession because of defective manufacturing.... yes, it is a safety issue even more because my family is sometimes using this truck and may not always react the same way that I would if something happened going down the road.... it needs a recall on these trucks

I am sending this report in regards to investigation PE25001. I own a 2024 Silverado 6.2L, purchased on 8/30/24. On 12/27/24, I noticed a odd noise coming from the exhaust and took the truck to the dealership. After a week of trouble shooting, the dealership with the help of technicians from Chevrolet, discovered the crankshaft play was 3 times out of limits causing the exhaust to rattle and determined that engine would have to be replaced.

I was driving down the road when the vehicle shut off and required a restart. After I was able to safely pull to the side of the road with zero power I was able to restart the vehicle after a few tries. The check engine light came on. Upon getting the code checked the CAM sensor is what shut the vehicle off. I was on a busy access road and a crash could have happened if I was not able to move out of the travel lanes.

The tailgate opens while I am driving. I saw this is an issue with other Models but it has happened numerous times on my model as well. The computer system also malfunctions sporadically and the car doesn’t turn off.

Unknowns at the moment- truck is at dealership. Dealership stated they have no codes to diagnose the issue. While traveling, most notably @35-45mph, there is a vibration, seemingly through the transmission or transfer case. You can feel it slightly through both the steering wheel and the fuel pedal, along with hearing it. I’ve taken it in several times and told there’s no issue. I will not accept the vehicle back until they are able to explain the issue and repair it. I noticed the issue around 20k miles. I recently took the vehicle to the shop with 32k miles on it as it is progressively getting worse.

Vehicle spun a bearing in the lower part of the engine after 1147 miles of use.

The 6.2L engine suffered lifter failure while the vehicle was in motion on the highway. This was after 5 months of ownership and only 2,800 miles on a new 2024 Silverado. The vehicle months prior to the failure emitted a chirping sound like a loose fan belt. Dealer stated it was valve noise. It got louder prior to failure. The dealer repaired the engine and replaced all 8 cylinder lifters. Now the same noise is back.

The issue involved multiple systems, including the ABS system, brake system, and electronic stability system (ESG), along with a significant loss of braking power. These components may still be available for inspection. My safety and that of others were seriously at risk during my morning commute in the Atlanta metropolitan area. The truck lost braking capability, nearly causing a collision with the vehicle in front of me. Later, as I attempted to park, it again lost braking force, and I narrowly avoided crashing into bushes. The collision prevention system also failed to activate during these incidents. The problem was inspected and diagnosed by the dealership after being towed via roadside assistance. They confirmed that the battery caused the failures across multiple systems. This was not the first issue with the battery. About a month ago, the battery suddenly died, preventing the truck from starting. At that time, Chevrolet sent me a message stating that the battery status was critical. After recharging it, the vehicle functioned normally until this recent incident. The first symptoms of the latest issue appeared while I was stopped at a red light. The truck suddenly shut off and restarted on its own. Warning lights for the ABS system and brake system appeared on the dashboard. Once the light turned green and I started to accelerate, an ESG message appeared, followed by another message limiting the maximum speed to 43 mph. When I tried to brake to park the truck, the brakes were slow to respond, making it feel like the truck had completely lost braking power. The collision prevention system failed to activate, increasing the danger. Fortunately, my two babies were not in the truck at the time of the incident. This was an extremely frightening situation for me as a driver. The truck is only six months old, has 37,000 miles, and was purchased new. I believe many of these failures could have been prevented with proper safeguards. While I was lucky to avoid an

On 1/13/25 while driving my new vehicle and arriving at destination I placed vehicle in park for 10 mins and then left putting vehicle in reverse and transmission in reverse would not engage, rolling me into decline slope and almost crashing into home. After receiving help to push vehicle in neutral, I placed car in drive and sent to dealership. Truck seemed fine in drive. Parkway Chevrolet, Tomball, TX inspected vehicle and stated no issues. Possible torque lock but nothing showing and possibly resolved. On 1/16/25 while driving to work, I stopped at gas station for coffee, left truck running. Got back in vehicle and placed in reverse, and again truck would not engage reverse. I received another push out in neutral , placed in drive and then proceeded to return home. While I’m drive check engine light came on, and truck would not go beyond the 2nd gear. I stopped at closest light to turn around and proceed home and the vehicle began grinding gea and jerking my vehicle while in drive. I tried to turn around at a dead end road and could not reverse vehicle and called for tow to dealership. Dealership at opening 7am took in vehicle 2 nd time with my complaint and called at noon. They stated the valve body of transmission needed to be replaced. Further stating it was a faulty issue chevy was aware about but nothing showing and recalled. They said no longer using manufacturer for this transmission replacement and it would be an unknown eta for repair. This is dangerous and unacceptable as it is a new vehicle with a known faulty part.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving 60 MPH, the vehicle began jerking and sputtering and then stalled. The engine turned over, but the vehicle failed to start. The vehicle was towed to the local dealer, where it was diagnosed and determined that the fuel pump module needed to be replaced. The vehicle was repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 8,840.

Blown transmission valve body at 8000 total miles. Truck went into limp mode and will not reverse. Can not be safely driven. Has been sitting at dealership for 2 months now waiting for parts from GM. National backorder no ETA.

The automatic power running board of my vehicle has been coming loose. I took the vehicle to my dealership to get serviced. They said they tightened the bolts, and that the board is still loose. They also say there is nothing else they can do to fix the issue. This seems like a significant risk, as this component of the body of my car is at risk of coming apart further due to rattling while driving. I would like your help figuring out a safe solution.

I purchased my vehicle in July 2024 brand new. I started to experience an engine shudder at about 4500 miles with the truck coasting or on the accelerator around 1500 RPMs. It first began at lower speeds around 40 mph, but now I feel it at high speeds as well. I brought my truck back to the dealership three or four times and they told me that the shudder was due to the active fuel management system in my 2.7L Turbomax engine. A different dealer said that it felt like a torque converter. There are no lights on the dashboard. The dealership I bought it from failed to try and flush the transmission fluid, only documenting that they did not feel the shudder on the receipt they gave me. However, during the test drive, they told me that they can clearly feel it. They failed to give me an explanation why there was no shudder for the first 4500 miles, and that it just started. They also stated that they had not heard of this problem yet, but said that it felt completely normal, which does not make much sense.

I purchased my vehicle from Mak Haik Chevrolet 11711 Katy Fwy. Houston, TX 77079 on [XXX]. Approximately 4 months my Check Engine Light came on and I brought my Truck to Mak Haik Chevrolet to have it checked out. The Service Department could not figure out why the Check Engine Light had came on. They did complete the Recall N242435631 regarding a need to update the radio and serial communication firmware on my truck. On Saturday November 9th 2024, I brought my truck into Mak Haik Chevrolet for the 2nd oil change at approximately 10,000 miles, and the technician could not get the truck to go into reverse. I was given a loaner vehicle and told that they would contact me about the issue once their transmission technician could look my truck on Monday. I was contacted on Monday November 11th2024, and told that the Valve Body in the transmission was defective. Jim Cox, Service Advisor with Mak Haik Chevrolet, explained that he could not find the part, as this is a big issue with Chevrolet across the Country, and he would let me know when he has access to the part. I asked about replacing the transmission instead, and Jim explained that he could not get those in either? Mak Haik Chevrolet has had my truck since November 9th, 2024.

my vehicle suddenly experienced decreased acceleration on the highway. A warning message appeared on the dashboard indicating reduced acceleration. When placing the vehicle in Reverse, the vehicle was not able to move in reverse. The dealership diagnosed it as a valve body needing replaced.

THE TRUCK FAILED GO SHIFT INTO REVERSE. HAD TO PUSH THE VEHICLE OUT OF THE PARKING SPACE. WHEN I TRIED TO GO FORWARD THE VEHICLE SHUTTERED AND THEN SHIFTED INTO LIMP MODE. DEALERSHIP HAS HAD THE TRUCK FOR OVER 8 WEEKS NOW AND I AM TOLD THERE IS A NATIONAL BACK-ORDER ON THE NEW VALVE BODY BECAUSE OF THE NUMBER OF TRUCKS REQUIRING REPLACEMENTS.

Every time I tow my travel trailer within 150 miles or so I will get a message that the Diesel Exhaust fluid (DEF)is low and needs to be filled soon. Within 50 miles of that happening I will get the message that the DEF is low and will be speed limited in 500 miles. When I stop and fill the DEF fluid it only takes about 2.5 gallons which isn't even halfway empty. When the Speed Limited to 65 in xxx miles warning comes on you are unable to view any other safety related information such as tire pressure or temperatures. I took my truck to Classic Chevrolet in Grapevine, TX. in September and they kept a 6 month old truck for 23 days. They said there is an issue with the DEF software algorithm while towing and they don't have a fix. They have a technical service bulletin that tells them to instruct customers not to add DEF until they get the Speed Limited in xxx miles . In other words don't fill it up when it says it's empty. The DEF system is a government requirement and the manufacturer should be required to ensure that their system is accurate and working under all driving conditions.

blown valve body , i bought the truck less than 6 months ago

Vehicle would not go in reverse or shift out of First gear Diagnosed as needing a transmission valve body replacement

Only 6k miles. Couldn’t go in reverse or get out of 1st gear. Brought to dealer, they said it needs a new valve body gor the transmission and there are so many trucks with this issue the part is on b/o for 2 weeks-3 months! In the meantime I have not truck.

Vehicle cut off while driving down the highway and wouldn’t restart. Had to be towed to dealer with a faulty fuel pump control module

I am writing to formally report a critical safety issue involving the torque converter in my vehicle, which has put my safety and the safety of others at risk. The problem began when I noticed rumbling noises emanating from the underside of the vehicle while driving at slow speeds on any type of road. There were no warning lamps or messages displayed on the vehicle to indicate an issue. This lack of advance notice left me unaware of the potential danger, increasing the risk of an accident. Upon having the vehicle inspected by a certified dealership, it was confirmed that the torque converter had come apart. This malfunction significantly compromised the vehicle’s drivability and posed a serious safety hazard. Sudden loss of power or reduced control, which could occur due to such a failure, puts both the driver and other road users at risk of an accident. I am deeply concerned about the implications of this issue for other vehicles that may have similar defects. I urge the NHTSA to investigate this matter promptly to determine if it represents a broader safety concern and to ensure that appropriate measures are taken to prevent further incidents. Please feel free to contact me for any additional details or documentation related to this issue. I appreciate your attention to this urgent matter and look forward to your response.

Valve Body on transmission failed at 9000 miles resulting in extreme reduced acceleration and it being unsafe to drive. No warning lights appeared until after the part failed. Failed valve body has been confirmed by the certified dealership service center. Replacement valve bodies are unavailable from the manufacturer GM. GM has not issued any formal recall for this part and searching online forums, this is a very common part failure for this vehicle.

I was taking a left from a stop sign onto a busy boulevard and as soon as I had passed the median I started losing acceleration and it felt like the transmission or engine was glitching or lugging. The engine began to try restarting itself possibly from the auto start-stop however I was now almost at a dead stop in the left hand lane in the dark. I promptly attempted to turn my hazards on, but they would not turn on while it was trying to start so I held the brake pedal down for light. I tried to turn the truck off and turn it back on however the hazards still did not work, none of the gauges went off when the truck was turned off, IE gas and voltage gauges were stuck. After attempting to put it into park and drive a few times I was finally able to turn the truck off, open the door and close it. At this point I was finally able to get the hazards turned on, however, it seemed like they would not stay on when the truck was trying to start so I could get out of the left hand lane. Fortunately someone stopped and we were able to push the truck off onto the median. After about a dozen attempts, the truck finally started, with the last attempt pumping the gas repeatedly for about twenty seconds. I drove hit for another twenty minutes and it drove okay with the engine light on. Onstar diagnostics mentioned possible fuel pump relay. I will note I did test drive a same year GMC equivalent model, and as the dealer went to gas it up, it would not start again. It ended up being the fuel pump relay.

I purchased my truck in August of 2024, new off of the lot. Within the first week there was an issue with the infotainment system of the truck with muted all audio. This includes all safety features that have audio alerts, navigation, stereo, blinkers. Anything audio is affected. This has now happened to my tuck 6 times since purchasing it. I have researched this online, and it has been a common issue since at least 2022 with no solution by Chevrolet. I have concerns since this affects all safety features built into the truck.

The forward collision warning light just came on and has been on for five days. Nothing happened, no wreck, no bumping into anything. I have researched and found others that have had the same problem. I tried removing the F11 fuse and leaving it out for 15 minutes as well as replacing it. I’ve insured that the windshield is clean and cameras are not blocked. I’ve used the settings in the main screen to turn the option on and off and it still stays on. I’ve checked for updates but didn’t find any. I called the dealership and they couldn’t help and said bring the truck in.

My husband hit another vehicle, then proceeded across the road and crashed into a telephone pole. The airbags did not deploy. However the vehicle called onstar to report the crash. The nc state trooper and the towing company both indicated that they were also shocked that the air bags did not deploy. This is a brand new vehicle with 1100 miles and has been declared a total loss due to the severity of the front end damage. The the body shop was also commenting on this fact.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while the vehicle was in the driveway, the vehicle was shifted into park and the parking brake message was illuminated. The contact stated that after disconnecting his boat trailer from the vehicle, the vehicle accelerated across the street and stopped. Additionally, while driving on three occasions at undisclosed speeds, the throttle was sticking. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,800.

all camera work off and on had it at dealer 6times cannot fix it

On [XXX], my Chevrolet Silverado 1500 Custom, Trail Boss 7,500 miles lost immediate power during driving operations. I was accelerating from a stop and my truck immediately lost power and my RPMs rose drastically without any power to my wheels. In an instant, the truck surged in power and continued to loose it while in traffic. I had to control the vehicle by slowing down. The check engine light appeared and warning messages to reduce acceleration and drive carefully. All of this occurred violently and without any warning. The truck reduced speed on its own and allowed me to drive 35 mph for two miles into the dealership which happened to be close. There is an extreme risk here for anyone who is driving at interstate speeds and this were to happen. After experiencing this incident, I was told the transmission or the transmission valve body required to be replaced by the dealership. I researched this later and discovered an extensive list of year models with the same problem. I was told services bulletins have been issued on this issue, but this is a serious risk to loss of life. I was told today Chevrolet doesn’t have a solution to the valve body problem and I would be without my vehicle until it is found and repaired. I am requesting a formal investigation. My truck is located at Tom Gibbs Chevrolet, Bunnell , Florida. [XXX] , [XXX] , [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fuel system failed and cause damage to the engine. Failure of motor can cause loss of power steering and brakes. Dealership confirmed that a fuel injector made contact with piston and deposited debris into the motor. No warning lights of error codes prior to event.

The dashboard is cracking and falling apart.

Per the dealership service department the Valve Body went out and it is a manufactured misbuild

On 10/14/2024, My vehicle got broken into and my gun, magazines, and gun case got stolen. The vehicle alarm system did not go off. This is a safety issue, in addition, it is a manufacturer defect.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving 45 MPH, the service brake warning light illuminated. The contact stated that while attempting to stop the vehicle, the brake pedal was depressed; however, the vehicle failed to respond. The contact smelled an abnormal odor coming from the brakes. The vehicle was taken to a dealer where it was determined that the front brake pads were rusted and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 4,000.

While towing a travel trailer from Texas to New Mexico I began to receive DEF 298 miles range remaining after about 3 hours of driving. About 30 minutes after range warning I got another warning that now the tank fluid is low and needs to be refilled. I stopped at the next gas station to fill the DEF tank with fluid but it only took about 1.5 gallons to top it off. I believe it holds 7.7 gallons. Back on the road the DEF level did not reset and it gave me a warning that in 500 miles I would be speed limited to 65 MPH. While this warning is displayed it is not possible to view tire pressure, transmission temperature or any other vital information about the vehicle. The countdown continued and when I reached my destination I had 298 miles remaining. I topped the DEF tank off once again and it took 1.5 gallons again. This only brought the level back to "low add fluid'. After 2 days of driving without the trailer the DEF level returned to full. When I began the return trip with a full DEF tank I made it about an hour before I received the 300 mile range warning. I refilled it at every fuel stop with about 1 gallon. It remained at the 300 mile range warning throughout the trip and after. My issue with this system is that it could render the vehicle undrivable in the middle of nowhere hundreds of miles away from a Chevrolet Service Center. The DEF system especially when it is verified that the tank has fluid and is actually using it normally should be able to be bypassed to make it to a repair center. I forgot to mention that this is a new vehicle 4 months old with about 4000 miles on it. It has been in the Chevrolet Service for 3 weeks and has not even been looked at.

After picking up my car from Autonation Chevrolet for the same issue I am reporting, I was driving, and the car dashboard lights all came on. The AC stopped working, too.

The Bluetooth handsfree system has sound problems within incoming and outgoing calls. The radio is working between, Sirius XM and Bluetooth music from the cell phone, with no issues along with AM and FM transmissions. However, when on the phone there are random crackle noises from the speakers. Most of the time it's when they're pronouncing letters that creat a higher pitch sound in normal conversations followed with the crackle. It's happening throughout the call and is consistent on every call. Test were completed with the Dealership’s Service Adviser where we replicated the issue with his cell phone separate from mine. After researching this, I have discovered is is not an isolated problem. Please see the following link where others are expressing the same problem: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to request urgent assistance with my Chevrolet truck, which has experienced several serious issues recently. On September 25, 2024, while driving, the steering wheel became stiff, and the engine's power stopped. The dashboard lights remained on, and I was unable to start or turn off the vehicle. The Chevrolet app initially indicated an airbag system issue. However, the next day, it reported problems with the engine and transmission system. I scheduled an appointment with the Bomnin dealership for September 28. When I arrived, the service advisor informed me that due to a backlog, the truck could not be inspected immediately and advised me to return in a month. Consequently, the vehicle has not yet been seen by a Chevrolet mechanic. On September 29, the Chevrolet app also indicated an issue with the anti-lock braking system. To date, I have not received a clear explanation or resolution for these problems. I would greatly appreciate any assistance or guidance you can provide to expedite the repair process and address these issues as soon as possible. Thank you for your attention to this matter.

1. Experiencing intermittent hard shifting accompanied by shock and noise, 2. Unexpected shifting and shifting delays that cause rapid RPM increases. These issues were primarily observed at low gears and worse with stop and go traffic. The check engine light appeared approximately one month after noticing these symptoms.

WHILE USING CRUISE CONTROL ON FREEWAY AT APPROX 70 MPH WHEN HEADED UP HILL AND THE VEHICLE REACHES APPROX. 2500-3k TACH, THE CRUISE WILL DISENGAGE AND SPEED WILL DROP IMMEDIATELY WITH NO WARNING. DEALER SAYS MANUAL STATES ONE MAY HAVE TO USE THROTTLE TO MAINTAIN SPEED BUT DOES NOT MENTION CRUISE DROPPING OFF. THIS IS AN EXTREME SAFETY RISK WHEN A VEHICLE IS BEHIND YOU ACCELERATING ON THE SAME INCLINE AND YOU SUDDENLY DROP SPEED WITH NO BRAKE LIGHTS ILLUMINATING.

The interior of the 2024 Chevy Silverado is trimmed in chrome accent pieces. These trim pieces reflect the sunlight directly into the drivers' eyes while operating the vehicle causing blinding reflections. I have had 2 near miss collisions because the reflection from the trim pieces blinded me momentarily.

I had a car accident in Mexico while I was driving inside the beach

Vehicles dash restarted while driving. All error lights came on and the dash cycled back up like when starting the vehicle. This is a safety risk because you cannot see any info on the dash, including speedometer, RPMs and fuel level! I spoke with the dealer, and the dealer stated if they cannot re-create the problem. There is nothing they are able to do and they have not heard of this before. There were no warnings at all for this issue.

Bought my truck new in March, after just 1 week i took my truck in after i noticed a loud rattling sound. Dealership replaced the rear section of the exhaust. After just a few days the noise came back. Now GM wont do anything about it. Truck has 11k miles on it now and the noise continues to get louder. Truck is available to be inspected. I dont feel the truck is dependable. Dealership has heard the sound again but wont do anything because GM wont pay for another exhaust system. No warning lights.

As I stopped at a red light, I received a message on my instrument panel to “push state”. I noticed my RPMs were at 0 and my vehicle was in neutral. I attempted to shift into drive, but received the same message again. I already had my foot on the brake as I was stopped, so I pushed the start button. The vehicle began its normal startup sequent and my RPMs return to normal. I shifted into drive and was able to continue to where I was headed. At no time did I ever shift the vehicle into neutral or turn it off.

Back up camera and other cameras intermittently stop working and an error pops up on the screen. Could be a safety issue when reversing.

The cluster that makes my dash gauges visible has failed and malfunctioning. The safety concern is that I cannot see my speed, my tire pressure, mileage, and I will not be able to see if there are other issues wrong with my vehicle since the entire dash gauges are not visible. The system is not resetting while driving and I lose power when it does that. I have to guess when to put gas or put the risk of myself and other drivers of my vehicle stalling out in the middle of a highway. The issue has been inspected by a dealer during an oil change and they even left a note for me that they were unable to reset my oil mileage because the system is not working. The dealership performed a system test and performed an update and they confirmed that did not fix the cluster issue. There were no warnings before this happened.

Tire: 275/60R20 I was driving at the top of Bay bridge, MD and the rear tire just blew up and automatically messaged came on the gauge cluster and my phone that there’s 0psi in the tire so I had to stop on top of the bridge and put a spare on which was quite dangerous but I had no choice because I couldn’t drive on the rim, tow truck showed up and helped me, I had only couple ladders on the back so there was almost no additional weight on the tires and at only couple months old vehicle with only 4,900 miles this should’ve happened. I automatically went to the dealership that I bought the truck and showed them the picture where it happened and what exactly happened and at first they wanted me to pay for the tire but I insisted that they will have to replace it for free because they sold me a vehicle with defective tire so days later they did install a new tire as a one time courtesy they said, but I did check on this tire and there’s a 3yr free replacement warranty if it’s a defective tire but the dealer didn’t tell me that, so now I wonder if any of my other tires will have the same defect?

Rear back up camera and front camera only work intermittently. This is concerning when backing up in congested areas such as busy parking lots and backing out of driveways. The dealership has been made aware of the issue, but I have not had time to take the truck in to get assessed. The only warning I get is a blank screen with a ‘X’ and a camera icon.

The interior of the updated 2022+ Silverado 1500 and 2024+ HD Silverado has multiple chrome surfaces lining various components of the dash and center console. When operating the vehicle during daylight hours, the reflectivity of the chrome reflects sunlight and directs glaring light into your eyes at various angles. This glaring and dazzling light reflection causes a direct blinding irritation to the driver that interferes with visibility outside of the vehicle and reduces the driver's ability to safely identify and react to changes in the roadway or surrounding traffic. This is an issue that is widely reported by a multitude of owners across online forums and social media groups.

The lower portion of both headlights frosts on the inside of the lamp at temps below freezing. The frosting limits the projection of the beam at night. This problem must be corrected through a recall. GMC has a BULLETIN on this problem, but does not offer a fix.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at various speeds on newly paved roadways, the front end of the vehicle was darting around while steering. The vehicle was taken to the dealer, where the tires were replaced; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure and recommended the contact to replace the tires. The failure mileage was approximately 700.
