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.

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.

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.
