Rear vision camera failed from water intrusion. Blank screen. Dealership agreed it was water intrusion and charged $600 dollars to fix. Similar to GM Recall A262554900 and NHTSA ID: 26V212 / GM Campaign N262551720 for different Chevrolet models of the same age as this vehicle.

Catastrophic engine failure. This happened after the recall inspection and fix engine has been replaced already under waranty. The GM dealer did a good job

Engine wiring harness. Apparently engineeed, designed or installed poorly. With normal use, multiple points are subject to wearing of insulation or wire fracture. While on cruise, transmission went into limp mode. Dealer verified exposed wire, replacing entire harness.Chevy has service bulletins out on the issue but nothing to the customer.

I pulled off the interstate after traveling 70mph with cruise control on. I then pulled into the Walmart parking lot and started to enter a parking spot rolling at 5mph and accidentally brushed the resume cruise control and the truck shot me forward and I came within inches of the car ahead of me because the truck suddenly started accelerating.

GM Is refusing to pay or provide towing for this recall. I live in southeast [XXX] and they are paying to barge the truck from here to [XXX] but refuse to pay for towing from the barge to the dealership and from the dealership back to the barge line in [XXX]: they said I live 1.5 miles from the barge line. I live 900 miles away from the [XXX] barge line. They are refusing to pay for a tow that is THEIR fault. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Conditions: Night, Raining, apx 50*F. Traveling on the highway apx 70 MPH with a loaded 18ft enclosed trailer (within the advertised towing limits of the truck). I accelerated to pass a tractor trailer. the transmission attempted to downshift, resulting in a loud bang and shudder. I attempted to accelerate once more. This time the transmission tried to shift, the rear wheels stopped turning for a second or two, resulting in a slide and requiring steering input to maintain the vehicle traveling straight. The rear wheels unlocked and began turning again. I coasted down to apx 55mph and attempted to maintain a lower speed until the next exit. While trying to maintain a safe speed for surrounding traffic, the transmission attempted to downshift. This time resulting in apx 4-6 seconds of the rear wheels stopping and skidding, resulting in a slide situation requiring steering input to remain in control of the truck/ trailer while the rear tires slid. I stopped on the shoulder, locked the truck into gears no higher than 4th gear and drove to the nearest dealer without further issues.

On October 9, 2026, I was driving my 2024 Chevrolet Silverado 1500 RST on a rural road at approximately 35–54 mph when the engine unexpectedly shut off without warning. There were no warning messages or indications of a problem before the engine stopped running. The instrument cluster remained illuminated, but the vehicle lost engine power and propulsion. I was able to bring the vehicle to a stop safely without an accident or injuries. However, the sudden loss of engine power while traveling at road speed created a serious safety concern. After the vehicle stopped, I attempted to restart the engine. The engine would crank normally but would not start. Diagnostic trouble code P129F was identified using a scan tool and was also displayed through the Chevrolet application. The vehicle is currently at an authorized Chevrolet dealership for diagnosis and repair. Based on the diagnostic code and reported symptoms, a failure of the fuel pump control module is suspected, although the dealership has not yet confirmed the cause. I am concerned that a sudden, unexpected engine shutdown could result in a collision, particularly if this failure occurs at highway speeds, in heavy traffic, or in a situation where a driver cannot safely move the vehicle off the roadway. I am requesting that NHTSA document this incident and evaluate whether a potential fuel pump control module defect presents a safety risk to owners of 2024 Chevrolet Silverado 1500 vehicles.

While traveling down the road at approximately 65 mph, I lost all power to the truck while towing an empty 3500lb trailer. I was unable to restart vehicle and had to have it towed to a dealership at my expense.

Driving down interstate about 65 the light on dash came on stated low engine oil stop engine at same time could smell smoke and saw smoke coming from under hood. I pulled over as fast as I could and by that time the smoke was pouring out from under hood. I turned engine off and I popped hood got out and slowly opened in case was on fire. It was not but I saw oil all over my engine and dripping from under vehicle. The front tire was covered with oil as well as down side of my truck. I saw where I pulled over a long oil streak. Oil kept leaking oil and large puddle formed under engine on side of road.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving 10 MPH and pulling into a parking lot, the vehicle unexpectedly lost motive power. The message “Shift to Neutral and Press the Start Button” was displayed. The contact was concerned that the failure was a safety hazard and could pose a safety risk to the contact and others. The failure mileage was approximately 54,265.

Tried to start the Chevy Silverado 1500 remotely and it was unresponsive using the remote start key fob. The truck was then started with the push start button inside the truck. There was no instrument panel errors or warnings when the truck was first started and began driving it. Upon taking the truck out of park and starting to drive, the brake pedal was extremely hard to push, and the steering was extremely hard to turn. It took a long distance to stop the truck while moving very slowly in a parking lot. The truck was also very hard to steer as if all power steering assistance had failed. The truck was put in park. Immediately after the truck was shifted into park, the instrument panel reported ABS, powertrain and steering column lock errors. After being turned off for 20 minutes, it was restarted and the only error on the instrument panel was a check engine light. The brake pedal pressure returned to normal and the breaking started working. The steering was now easy to turn and working as well. It was drove slowly, a very short distance to the dealership where it has been for the last week and a half. They have diagnosed and replaced the ECM, ABS and master cylinder. They continue to receive braking system error codes.

My vehicle was serviced for the Chevy L87 recall a couple of thousand miles ago. It currently has 13343 miles on it and I was driving down the road and then all of a sudden the engine just stopped and my vehicle lost power leaving me stranded on a state route XXX in [XXX], which is a dangerous route with nowhere to pull off. This issue has been going on for years now and Chevy needs to make this right. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While operating the vehicle, the front electric drive motor suffered a failure, triggering reduced propulsion warnings and rendering the primary electric powertrain inoperable. The vehicle was towed to an authorized GM dealership service center, where the defect was confirmed. To replace the failed front drive unit, technicians had to drop the front subframe cradle and completely dismantle the front suspension and steering assembly. During inspection of the disassembled components, severe mechanical galling and metal scoring were documented on the cast aluminum front steering knuckle mounting boss. Reinstalling suspension and steering hardware against structurally compromised, gouged aluminum presents a severe safety hazard of metal fatigue, stress fracture, or joint failure under dynamic loads. This vehicle is factory-rated to tow heavy loads. Dynamic cyclic forces transferred through a compromised front knuckle assembly—particularly when towing on a weight-distribution hitch—create an acute risk of structural failure and loss of directional control at highway speeds. The vehicle has remained grounded and out of service at the dealership for over 50 continuous days undergoing this high-voltage and chassis teardown.

2024 Chevrolet Silverado 1500 LTZ, 3.0L Duramax. When the DEF system begins displaying the “miles until 65 MPH max speed” warning, the warning takes over the Driver Information Center and cannot be acknowledged or dismissed with the steering-wheel thumbwheel. This prevents me from accessing unrelated DIC information, including Trip 1/Trip 2 and other vehicle information, potentially for hundreds of miles. The truck recently received the latest available software update. I am requesting that GM document this as a software/usability defect and provide a case number. The DEF warning should remain available without preventing access to other DIC functions.

Got my truck back yesterday from in shop for 2 weeks from being repaired. Got to red light just stopped my engine shuts off. Dash shows engine/transmission problems. Exact same thing happened two weeks ago. Had to get towed into dealer again this am

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that the vehicle had been experiencing inaccurate DEF gauge readings since the purchase, and the failure mostly occurred while towing a camper or trailer. The contact stated that while driving 70 MPH on the highway and hauling a camper, the message that the DEF tank was empty and needed to be refilled was displayed, and the vehicle went into LIMP Mode and decelerated to 35 MPH. The driver continued driving and pulled over to a safe location. The vehicle was taken to a dealer, where it was determined that the DEF tank needed to be replaced; however, the manufacturer denied authorization because the required preliminary procedures had not been completed. The manufacturer General Motors LLC was notified of the failure by phone. The failure mileage was approximately 4.

OnStar Telemetry Control module suddenly failed. Systems such as automatic crash detection, directions, mapping and OnStar emergency connection and SOS all not working. Rests did not work and truck is at the dealership for repairs. Internet reports that this is a common issue with 24-25 models but GMC not proactively repairing or compensating owners for repair. They issued a service bulletin for some models but are resisting a recall to address safety issues. GM Service update N262547330.

2024 Silverado 3.0 Rst turbo replacement, followed by engine replacement at 80K miles. Advised the dealership about the transmission at about 85k miles. At 103,000 miles the transmission failed. GM is denying any responbility. This is already a known issue yet GM keeps denying it. Major saftey issue from the beggining of the purchase. Every complaint has been noted by the dealership.

From a stop during fast acceleration made a left turn and rear section or rear axle sounded like it went over a speed bump or wheels locked up, then transmission felt like it was in high gear, did not want to move , or very slowly , i accelerated rpm was 2k or 3k still moving very slowly, this was in heavy traffic. I notice that check engine light went on with TC, parking brake service , some pad lock ( dont know what the ped lock is). 2nd time this happen the parking light service light went on and the brakes locked up again in traffic. 0

Original 6.2L engine was replaced subsequent to NHTSA Report 11724274 from Catatrophic engine failure on January 31, 2026 at 25,274 miles. Original engine was manufactured on May 30, 2024, but Silverado HC was manufactured on June 9, 2024, so it was not captured in existing NHTSA Campaign 25V‑274 and subsequent GM 6.2L Recall and is not currently included in expanded factory 10/150,000 powertrain warranty. Due to original catastrophic engine failure due to crank and connecting rod, covered transmission damage was discovered, truck is currently on third Torque Converter and Transmission has been out of truck for repairs to Valve Body and 4-10/reverse piston twice. Replacement 6.2L engine lasted 3,900 miles before exhibiting significant Lifter Tick Bank One/Driver Side, Tear down revealed failed lifter which wiped out a lobe on Cam. GM TAC refused engine replacement, instead replaced one Cam, 16 lifters and trays on Bank One. Drove truck for approximately 300 miles after repair and Engine began exhibiting significant knocking from bottom of engine, second replacement engine is now being installed. All routine maintenance and Warranty work has been performed and documented at GM certified Dealer Service Department.

The engines lifters failed in cylinder 7 . In which the engine had to be replaced. It has had all of the proper services on time.

I applied brake and pedal went straight to floor without any stopping. I had to steer into a ditch to avoid a collision resulting in more damage to steering system, frame, windshield and body. This was complete brake system failure and yes is available for inspection. I was in a very rural area at time and was able to avoid a collision however, if I had been in city or on highway it could have easily resulted in injury or fatalities. The problem is currently under federal investigation and has been widely reported as a serious problem which may soon result in widespread recall. The vehicle has not been inspected yet by dealership or anywhere else as it just happened 18 hours ago. There were no warning lights or chimes before the incident when pedal went to the floor. After incident dashboard lit up with warning lights including, Brake, ABS, Traction control, power steering, Collision system, Engine light, Steering Column and others. Truck speed limited to 43 mph. And pedal still goes to the floor without applying brakes.

This vehicle is a 2024 Chevrolet Silverado 1500 featuring a 6.2L V8 engine and a 10 speed transmission, currently at 58,136 miles. The vehicle was experiencing a severe shudder. An official GM Technical Assistance Case (TAC) engineering case was opened on July 30, 2026 confirming a verified DFM cylinder deactivation or valve train malfunction. However, on August 21, 2026 the dealership falsified the repair log by printing ‘Concern Not Duplicated’ to the manufacturer, while physically installing an unapproved aftermarket Range Technology DFM Eliminator module into the vehicle’s engine harness to artificially override the factory emissions and cylinder deactivation programming to mask the mechanical failure. This vehicle is part of the active NHTSA Engineer Analysis EA26005, and the manufacturer’s dealer network is actively using unapproved third party hardware shortcuts to evade mandatory warranty repairs before the vehicle’s 60,000 mile factory powertrain limit expires. I called GM to report and request a warranty freeze and regional field engineer to go to a different dealership and was told they can’t freeze a warranty because the TAC was closed on August 28, 2026 as resolved even though it was not resolved.

July 2025. 2024 Chevrolet Silverado 1500 Vehicle mileage 18k 6.2L engine. Lack of Propulsion under normal, in-traffic, highway operation at highway speeds.

Not that anything has happened to my truck but im genuinely worried that something bad will happen with my motor. With it being the 6.2L L87 motor. My truck was manufactured july 2024 which is 2 months after Gm's cut off. I love the truck but im worried about going to and from work, what if i was to turn and this truck dies and i go into oncoming traffic? What about everyone else driving their own vehicles? I hope something is done because im really thinking about getting rid of this truck in fear of something bad happening. Thank you.

Check engine light repeatedly comes on. Take it in, multiple Chevy dealerships “fix” the errors such as fuel line pump 5x, gear shift issues, modules that went bad and various other issues. I Routinely take care of vehicle (oil changes, tire rotations and service when needed) This truck will randomly shut off while driving (stop and go traffic ) I was told to turn off the start/stop which I do every time I get in the truck. However it recently wouldn’t turn over after going through a car wash, it would try and try till I manually stopped it. It’s running rough now and I pray everyday the check engine light doesn’t come on or that it doesn't just shut off mid drive. This truck has been hell on wheels and I bought it with 10 miles on it. Bought it from AutoNation in 12/2023.

This complaint is in relation to the investigation into the GM L87 (6.2L engine) investigation. I own a 2024 Chevrolet Silverado with the L87 engine. I had my truck inspected through the recall a few months ago and the engine passed at that time. The engine oil was changed by the dealer per the recall at that time. On August 23, 2026, I was traveling at highway speeds on an interstate highway when my truck began to lose power, downshifted hard three times and died in the middle of the highway. The truck shifted to nuetral and I was able to coast off the highway into a rest area. I attempted to start the struck but nothing happended. I had the truck towed to a dealer. They inspected it on August 25, 2026 and determined the engine had a catastrophic failure and needed to be replaced. I am currently waiting on a replacement engine

In reference to 2024 Chevrolet pickup, 6.2L engine, 10 speed transmission. The vehicle is available for inspection upon request. I believe the transmission is going into "partial lock-up" at full/highway speed. When traveling on highway with cruise control engaged, the vehicle suddenly acts as though the brakes are being strongly applied, slowing the vehicle at a very rapid rate, down as low as about 40 MPH. The vehicle slows quickly enough that the driver and passengers are thrown forward to the extent allowed by the seat/safety belts. The issue terminates itself at various times. The vehicle has been inspected by GM mechanics several times, but they cannot find the problem. There were no warning lamps, messages, service engine lights, etc. This has occurred on at least five (5) different occasions. The first occasion was at approximately 7000 odometer miles. The vehicle now has 25,100 miles. All incidents have been reported to GM dealership mechanics.

The contact owns a 2024 Chevrolet Silverado. The contact stated that while driving at 69 MPH when the vehicle experienced a total loss of automotive power and all of the warning lights were illuminated; a message was displayed on the instrument panel "Reduce Acceleration, Drive with Care" and the vehicle was towed to a local dealer where it was diagnosed and the contact was advised that engine had experienced catastrophic engine failure as a result of the pistons and rods exploding into the engine, and that the engine would have to be replaced. The vehicle was repaired, however the check engine warning light had remained illuminated. The manufacturer was notified of the failure. The failure mileage was 7,948.

The engine has a loud knock and tick noise, the dealership said vehicle was fine changed the oil to a thicker oil and sent me on my way. No messages or symptoms besides the loud noises engine still running but has loud knock and tick noise from time to time after the oil was replaced

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle stalled on several occasions. No warning light was illuminated. The vehicle was restarted and drove as intended. The vehicle was taken to the dealer several times, but no repair was performed. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), and the vehicle was taken to the dealer for the recall repair; however, the dealer informed the contact that the manufacturer denied authorization to perform the recall inspection. The dealer informed the contact that the failure appeared to be associated with the recall and replaced the engine oil with a higher viscosity oil. The contact was provided a work order confirming that the recall repair was not completed. The manufacturer was notified of the failure and referred the contact to another dealer. The vehicle was taken to Mac Haik Chevrolet (11711 Katy Fwy, Houston, TX 77079); however, the stalling failure could not be duplicated, but there were abnormal engine sounds confirmed. The second dealer requested authorization to disassemble the engine, but the manufacturer denied the request. The contact stated that the manufacturer failed to honor the recall repair, denied a buyback request, and offered monetary compensation, which the contact declined. The vehicle was not repaired and was traded in. The failure mileage was approximately 5,000.

Engine shut down. Last thing I saw on my screen was engine oil hot engine shutting down and engine shut down and had no electrical power.

2024 Silverado ZR2 with the 6.2L engine was involved in the GM safety recall N252494003 for L87 Engine Loss of Propulsion. Vehicle taken to local dealership where inspection was performed. Passed inspection on 11/11/2025 resulting in the dealership changing to higher viscosity oil per safety recall instructions. 27,000 miles on vehicle at time of recall inspection. On 2/24/2026 was using the on ramp to get up to speed on the interstate. Got vehicle up to 70 mph and suddenly without any warning had loss of propulsion and vehicle began to decelerate quickly in front of a tractor trailer. Fortunately the semi driver was able to swerve around me as I pulled the vehicle off to the side of the road. Vehicle towed to the dealership where I purchased the truck and diagnosed with engine failure. Multiple bearings went out sending metal fragments throughout the engine. Vehicle had 28,500 miles at time of failure. Dealership had truck for roughly a month to perform complete engine replacement. Truck currently has 32,000 miles on it and seems to be running okay. We have lost some trust in the GM brand after this whole issue. Another uneasy problem is that my wife’s 2025 GM SUV has the same 6.2L engine in it. We bought my wife’s vehicle in May of last year and are unable to move out of it due to being in negative equity at the moment with that vehicle.

6.2L engine stopped working on the highway.

Had the Motor replaced under recall / warranty at a certified chevy dealer. ~41k miles. 6.2L L87. GRAFF chevy of Chesterton Indiana. After long lead times and getting the run around, the truck was "done". picked it up and many things were still wrong/incorrect. They were able to take care of it. A day later, the truck died in the road. towed to another GRAFF dealer. 2 days later it was found to be a bad ground. fixed. Fast forward ~3k miles later. the transmission went out and locked up on a main roadway. Towed to another dealer (West Herr chevy Orchard Park NY). They found the root cause was due to transmission cooler lines coming loose from faulty installation during motor swap. There were also many other items found that were broken or loose under the hood of the vehicle from faulty workmanship. I am being told it is not covered under warranty because of the previous dealer's workmanship (GRAFF Indiana) I was able to get the truck put of the roadway and to a safe place, but this very well could've caused an accident, and I would like to document it.

Vehicle suddenly stalls and reduces speed at different times with no warning. At first it would show that message after car washes or rainy days but now randomly it’ll reduce speed in unexpected moments causing safety concerns. It reduces speed, stalls, drives forcefully, and shows a “reduced acceleration drive with care”. Sudden stalls have become a danger to my family and myself as we depend on this car to get to and from on a daily basis. Dealership states it’s the TCM but not covered under warranty. But the vehicle is new how is it that it already has defects

The contact had previously taken the vehicle to a dealer for NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the inspection yielded no visible issues, and the recall was marked as completed. The vehicle remained at the dealer and had yet to be repaired. The manufacturer had not been notified of the failure. The failure mileage was approximately 25,500.

Truck suddenly refused to shift gears/stopped moving forward in HEAVY TRAFFIC, placing me and my family--and others on the roadway--in danger. Dealership inspected the vehicle on three separate occasions for the same (recurring) issue, replacing the control valve body on one visit and the entire transmission on the third. No advance warning that the issue was about to occur on any of the three instances, but check engine light came on afterward along with a message reading "reduced acceleration/drive with care".

While I was visiting my mother in Kentucky my 6.2 truck engine failed. It all happened really quick and no warning signs prior. Truck passed recall in April 26. I just left visiting my mother at nursing home. I was on Mountain Parkway when it all of a sudden started making a noise. It sounded like it was coming through firewall. All of sudden check engine light came on and I pulled over right before off ramp. I turned truck off for couple of minutes and started it back up. No light but as soon as I pulled back onto parkway noise started again. I was next to off ramp so I pulled into Marathon gas station and as I was pulling in it died and wouldn’t start back. Truck was taken to dealership on 5/24. They said they can’t give me a courtesy vehicle due to me living out of state and I would have to get a rental on my own but GM would cover up to $44 per day. I contacted GM twice and said I needed to speak to dealer about getting a car. I explained what dealer told me but they said it was out of their control. Still paying for rental out of pocket. Dealer called and verified that engine needs replaced and new engine is back ordered with no ETA. I’m still paying truck payment on a truck I don’t have and no help from GM on giving a car to drive. Need help with escalating new engine replacement and rental that GM is covering.

Oil cooler failed and truck was at dealer for a month over winter. Now June 20th transmission failed and there is no timeframe on the valve body. I am still making payments on this truck and no dealers have a timeframe.
