2026 Chevrolet Silverado 1500

The engine in my 2026 Chevrolet Silverado ZR2 with the 6.2L V8 had a catastrophic failure. While I was driving, the engine suddenly shut off and seized without any warning. The dealer told me they found metal in the engine oil and oil filter and that the engine needs to be replaced. They also informed me the replacement engine is on back order for more than five weeks. The truck is available for inspection. How was your safety or the safety of others put at risk? My truck lost all power while I was driving, which put me and other drivers at risk because it happened without warning. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealer inspected the truck and confirmed the engine had an internal failure. They found metal in the engine oil and oil filter and said the engine must be replaced. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The truck has been inspected by the dealer. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No. There were no warning lights, messages, or other signs of a problem before the engine failed.

I suspect the automatic emergency braking suddenly activated while backing into my driveway. The truck abruptly stopped as if i crashed into something. The driveway was completely empty there was no reason for the vehicle to activate that system if that's even what happened. The dealer was no help i figuring out the issue they made no attempt to even try and diagnose it. I've since deactivated automatic emergency cross traffic braking and it has not happened since.

At approximately 3,000 miles, the engine began making a loud knocking noise that became progressively worse while driving. The truck was diagnosed as needing a complete engine replacement. No warning lights, no check engine light, nothing. For someone inexperienced with vehicles, you could easily be in big trouble on the highway and a potentially life threatening situation. My primary concern is that there was no warning that such a major engine failure was about to occur. An engine that fails with so few miles raises concerns about the possibility of sudden loss of power, loss of acceleration, or engine seizure while driving in traffic, on highways, or while towing. A failure under those conditions could significantly increase the risk of a crash. The vehicle has been out of service while I continue making loan and insurance payments on a brand-new truck that I cannot use. The replacement engine is on national backorder, leaving me without a clear repair timeline. After researching this issue, I found numerous reports from other owners describing similar failures involving the 6.2L V8 engine. Based on the volume of owner complaints, there appears to have been a significant increase in reported engine failures involving 2026 model-year vehicles. This suggests the problem may not be an isolated incident but instead could indicate a broader defect that deserves investigation. As a result of this experience, I no longer feel confident or safe driving this vehicle, even if the engine is replaced. I purchased a brand-new truck expecting long-term reliability and peace of mind, but instead I experienced catastrophic engine failure at only 3,000 miles. I respectfully request that NHTSA investigate these engine failures to determine whether a safety-related defect exists and whether further action is necessary to protect consumers. I have requested a buyback, but GM completely denies it. Such a horrible Expy with manufacture.

On XXX I leased this 2026 Silverado and I have discovered that this truck tramlines, basically rocks side to side on roads with longitudinal grooves in the concrete, meaning lines that go the same way you're driving, the truck will violently swag side to side. I have been pushed into oncoming traffic from this. On 7/17.26 I took my truck to Fox Chevrolet of [XXX] to get service about this issue. I took the general manager of theirs, Marc and he confirmed the issue. He said he would send the DOT number to GM and wait for their reply. He called me on 7/20 saying that GM informed him that this has been reported by others and there's nothing GM is willing to do and to just deal with it. I told him that I find that unacceptable and it needs to be looked at my someone higher up. He passed this to his service manager since he's going on vacation for the next week, Ron. Ron called me and said that he talked to the local dealer rep and that he claims there's a law that says GM can't change tires that didn't come on the truck and that this is a known issue with these tires and again to just deal with it. This is completely unacceptable and flat out dangerous! I had a 2024 Silverado before this truck and it never did it. It had different tires than this truck and that's my argument is the tires are the problem. The manufacturer, Michelin even said that the solution is to get different tires and it's known on these ones.

A.The engine is stalling while driving. This has happened four different times. Three times while towing, and one time while backing up a small hill. This is a scary situation because three of the four times almost caused an accident. 1.We were driving to Texas, pulling a pontoon boat. While exiting the highway, we were entering into an intersection at a speed of about 10 miles per hour, and the truck shut down. The truck said, “Start the motor and place it into gear.” Or something similar to that. 2.We were in stop-and-go traffic on the highway, and the truck shut down. Once again, I had to restart the motor and shift into gear. 3.We were entering a parking lot from the main road, and the truck shut down. Again, I had to restart the motor and shift into gear. 4.The three times above are during a time when we were towing. The fourth time is when we were backing up a small hill. The rear tires lost traction and spun for a second or two, and then the truck shut down and started to roll forward. Once again, I had to restart the motor and place it into gear.

I have been having issues with my vehicle for the last 1,000 miles or so where it appears to be losing power while accelerating normally, i'm not sure if the issue lies with the engine or powertrain/transmission. I took to dealer last week and they were unable to reproduce. The issues have been getting more frequent and intially were only occuring after the vehicle warmed up, now it has started while vehicle is cold. Feels like the power drops (rpms drop) during a normal acceleration. As of 7/16 I now have a check engine light on, onstar indicates an issue with my engine, transmission, electrical. This is putting myself at safety risk along with others as during my normal drive the engine is losing power and could either leave me stranded or cause an accident.

The forward collision warning is excessively sensitive to vehicles and pedestrians. I've had the alert go off recently for something so simple as pulling into a parking spot. It goes off frequently just driving past pedestrians and throughout what I consider to be normal driving where I am not coming close to a collision with a vehicle. It is very unsettling and startling when the alert goes off indicating that I am coming close to a collision with a vehicle or a pedestrian. I had a 2023 Silverado 1500 LT/2.7 Turbomax engine and it was not this sensitive. I fear that this may actually cause an accident at some point or if the emergency braking were to activate with another vehicle behind me.

On XXX I was driving from [XXX] to my sister's house in [XXX]. I was relocating to [XXX] for a job. I was pulling a U-haul trailer (6x12) that contained significantly less weight than the truck can handle. About halfway there, on back roads, the truck suddenly slowed significantly and the gas pedal was unresponsive. The light in the dashboard read Reduced Acceleration - Drive with caution. Pulled over, turned off truck, opened driver side door, to reset the truck (read this on google). We had to do this a couple times, because it would just go back to that behavior after a bit. We made it to my sister's house to stay the night. In the morning, XXX, I called the local Chevy Service Dept in [XXX] and asked if I could bring it in, I described the problem. During the drive to the shop, the same issue occurred. Upon arriving at the service dept, the Trailer app was giving a warning that the load may be heavier than max. Which cannot be true. The dealer techs said they had never seen anything like it before, but they seemed to know what to look for. They then informed me that they could not loan me a car because I was traveling out of state. I had a deadline, so my only option was to rent a U Haul box truck, unload the back of my truck into it, hitch the trailer I already had to it, and drive to [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
