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.

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.
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 the federal safety agency 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. Potential safety issue to myself or others, due to failure and lack of Propulsion. Issue was confirmed by dealer. Metal shavings in oil pan and oil filter. Bearing failure, recall item, however engine failure before recall engine could be replaced. Engine replaced quickly and without issue. Dealer was extremely professional, helpful, and a pleasure to deal with. UNKNOWN if vehicle was inspected by anyone other than dealer. UNKNOWN if any warning lights prior to failure. No messages or symptoms prior to failure.
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.
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.
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
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 the federal safety agency 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

Engine seized middle of road had to coast off into a safe spot to park
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.
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.
L87 engine failure
The 6.2 liter engine has been recalled. The problem is if you pass inspection you are now required to use a higher grade of oil. This results in an additional cost of about $50 per change. The reimbursement of the difference should have been covered by the recall as this was not an intended cost when I purchased the truck.
On [XXX], I was going to Atlanta, the truck started hesitating harshly while I was passing another driver on a two lane road. The truck wouldn’t accelerate and the paddle seemed to be stuck, I had to pull off the road to avoid a head on collision. On the 30th of May, I took the truck to Allen Turner in Pensacola, Florida where I purchased it and reported the issue, the service department was closed and they sent me next door to a Chevrolet Dealership, which was also closed. On today [XXX], I took the truck out for a test drive, and I had the same incident happen, but this time I pulled into a gas station and shutdown the truck. Once I turned the truck back on, the check engine light came on. I didn’t think I would make it back home, because the truck didn’t accelerate correctly, and when I pressed the gas pedal it didn’t accelerate and was making different noises. The pedal seemed to be stuck, with no acceleration. I recorded a little bit with my phone while trying to drive, but it’s not the best. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
L87 6.2L engine failed. Loud knocking, no oil pressure, engine stalled and would not restart. This happened despite GM's recall where they changed to 0W40 oil.
The primary failure is in the electronic transmission control system and engine wiring harness assembly, specifically throwing diagnostic trouble codes P0700 (Transmission Control System Malfunction) and P0717 (Input Speed Sensor Circuit No Signal). The authorized dealership identified a critical issue with the engine harness chafing, but their subsequent repair attempts have failed to resolve the recurring powertrain failure. The complete vehicle and all affected components are currently parked and fully available for immediate physical inspection at my residence upon request. While operating the vehicle at highway speeds, the powertrain abruptly loses throttle response and forces itself into a severe, uncommanded "Reduced Power / Limp Mode." This creates a severe safety hazard by instantly dropping vehicle velocity on active interstates and high-speed roadways, leaving the vehicle unable to accelerate out of harms way or merge safely, placing myself, my passengers, and surrounding motorists at immediate risk of a high-speed rear-end collision.The malfunction has been repeatedly confirmed and documented by authorized GM service agent Rountree Moore Chevrolet (Lake City, FL) across three separate service visits. The dealer confirmed the active trouble codes and attempted various repairs (including Transmission Control Module reprogramming on 04/24/2026, engine harness chafing repairs on 05/19/2026, and auxiliary fluid/battery adjustments on 05/21/2026). The persistence of the failure confirms the dealer has been unable to successfully remedy the defect. To date, the vehicle has only been inspected and worked on by the authorized dealership's factory-trained technicians. It has not yet been involved in a collision requiring police or insurance representative inspections, nor has a corporate field engineer from General Motors inspected it outside of the local dealership level.The failures are consistently preceded by an illumination of the dashboard Check Engine
