The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving approximately 10 MPH, there was an abnormal knocking sound coming from the engine compartment. The vehicle was reversed to the residence and parked, but the sound was heard longer. The contact stated that while the vehicle was parked, the accelerator pedal was depressed, and the sound from the engine compartment returned. The vehicle was towed to the dealer, where it was diagnosed, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 3,134.

The 6.2L V8 engine on my New 2026 Chevy Silverado Zr2 Bison blew up around 8000 miles. While driving on highway the car shutoff and shifted to neutral while I was rolling, where I then could put it in park and restart the car to move to a safer location. Truck was towed to dealership where codes cleared during the time getting it to the dealership, and was told it was good to go. About 2 miles leaving the dealership the engine had shutoff again except did not turn on. Dealership said the camshaft had cracked and wanted to replace the whole engine under warranty.

Truck has less than 1800 miles. Was at a stop light and the vehicle started shaking and making metal tin rattling sounds. Stopped for gas, started the vehicle all noises went away. Got onto the freeway and about 1 mile down the road the truck lost power at 70 MPH. I slowed down and the vehicle continued to lose power. I put my flashers on and started to pull over and the truck died, all dash lights went black and the truck was off. I rolled to a stop and parked the truck. Called a tow truck. The vehicle wouldn’t start. It turned over at first and then nothing. I was not able to shift the vehicle into neutral. The tow truck asked me to assist while we Dragged the entire truck into the flat bed trailer. Dealer called late after noon the next day. Saying the motor was seized and had to be replaced entirely. The service technician said this has been happening to the 2021-2024 6.2L engines as well and they’ve seen plenty of them. They recalled those a used a band aid fix of replacing the oil with heavier weight and a new drain plug. He said it’s not working and all those trucks are having the same issues. He said, this was not his first 2026 motor seized in a 6.2L. He’s had another one recently low mileage that seized also. I asked for a different motor. I was told not to worry we will give you a 3 year/100,000 mile warranty. The truck was $100,000! And now they only want to warranty it for the same 3 years, just higher mileage… The motor is on back order and no telling when I’ll get my truck back. This is my 3rd Silverado and my 2017 is still going strong with 100,000 miles on it. They have a serious consumer issue on their hands and should be buying these trucks back as we will not be able to rely on the new motors. Some people have had 3 and 4 motors replaced for the 2021-2024, 6.2L engines.

At about 800 miles i noticed ticking from the engine and random and intermittent jerking. Some of which were very severe that felt like someone rear ended me. I took into the dealer with my complaints. They kept my vehicle for 2.5 days and didnt give me a loaner. The my were unable to reproduce the jerking and said the ticking was normal. They showed me the ticking and said its normal and will go away after it warms up. They did a vehicle update and said it will help. They said theres nothing else they will do. I knew something was still wrong but felt like they wouldnt do anything and I couldn't give up my vehicle for days at a time. I continued to drive it and was planning on taking it to a other dealer for a check up. But at about 3500 miles. One day the truck began squealing and grinding. I attempted to drive the truck home and the truck just died on the freeway. Luckily I knew something was wrong so I stayed in the slow lane so it was easy for me to get off. Thats the first time the check engine light came on but it was too late. I had it towed to the dealer and they checked and it was catastrophic engine failure.

On Tuesday 01-20-2026, I was driving from Dallas Fort Worth to Oklahoma City, OK. I was driving down the highway I-35 at about 80 mph. Suddenly I felt a loss of power and my truck started to bog down. As I pulled over, the engine stalled out and would not start up again. It would crank but it would not start. My truck was towed to a dealership in Norman, OK. "Landers Chevrolet". I was contacted by the dealer the morning of 01-21-2026 informing me that my engine is going to need replaced. My truck is a 2026 Chevrolet Silverado LT Trail Boss with 6.2L and 6,457 miles on it. At this time, I don't have any paperwork or a copy of the repair order because the vehicle is still in the shop. The dealer told me that the motor is on order and should be here in 4-6 weeks. I purchased this vehicle on October 16, 2025.

Vehicle has less then 700 miles. Upon driving vehicle, the dashboard started losing information, no speedometer. When I tried to pull the truck over to the side of the road, the power steering was lost. It was nearly impossible to turn the wheel, then the engine stopped. I was unable to turn on blinkers or hazard warning lights. When I put the vehicle in park to try a restart the engine would not turn over. The transmission was locked in Park and unable to shift to neutral to try to push vehicle to safe spot. At this point I was blocking the road. Called for roadside assistance, two hours later vehicle was towed to Chevrolet dealership, were it is being assessed.
