I purchased a 2026 GM Chevy Silverado. At 500 miles all dash warning lights came on while driving, radio played static. I disconnected battery in order to reset the computer. At 1400 miles in the heat of south Florida the air condition stopped working. after completing my drive 60 miles away with no ac i disconnected the battery to reset the computer. The ac started to work after this reset. I went to the dealer and they wanted me to leave the truck. They could not provide a loaner and the fact that this is my only vehicle I could not leave it. At 2000 miles the computer screen stated that there was an update. The computer would not update when I pressed start update. The screen then said unable to update conditions not met go to the dealer. I went back to the dealer and they said there is no update and they reset the computer. THIS IS GOING TO KILL SOMEONE WHEN THEY PULL OVER ON THE HIGHWAY BECAUSE THE CHRISTMASS TREE ON THE DASH CAUSED THEM TO PULL OFF THE HIGHWAY AND A SEMI IS GOING TO KILL THEIR ENTIRE FAMILY WHEN THEY ARE STOPED ON THE SIDE OF THE HIGHWAY BECAUSE GM CANNOT MAKE A VEHICLE THAT WORKS CORRECTLY. PLEASE GO AFTER GM THE COMPANY THAT STOLE YOUR TAX DOLLARS WHEN THEY WENT BANKRUPT.

Driving at highway speed’s transmission was hard shifting on its own from Drive to Low and vice versa on its own the first time. Truck taken to dealer and was told that transmission needed an update. Second time driving at highway speed experienced hard shifting in rear and felt like I was hit from behind. Lost propulsion and check engine light came on. Was told that the valve body needed to be replaced. New truck with only 7,500 miles on it. My guess understanding is that this has been an issue with Chevrolet/GM 6.2 engines. Hard shifting and loss of propulsion accord while accelerating to pass another vehicle.

Driving at 70 mph when I tried to accelerate. Heard a loud bang from the exhaust and immediately started to lose power. I had zero warning that anything was wrong. Warning messages flashed and I lost propulsion. As I was pulling over the engine died completely and shut off. Purchased the vehicle on 11/25 and had 4100 miles on it. 6.2L Chevrolet ZR2. Dealer confirmed that that the crankcase failed which resulted in catastrophic engine failure. Currently waiting on new replacement engine..

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.

I purchased my new 2026 Chevrolet Silverado 1500 truck on 12/04/2025 from CMA Chevrolet in [XXX] . When the truck was delivered, there was no owner's manual with the truck. I recently found that there was a recall associated with this issue. It is XXX. I thought that maybe manuals were now online. When I read the recall, it said that it is federal law that one be issued with each new vehicle. My VIN is not part of the recall. I contacted my salesman and he said that their parts department said that sometimes the manufacturer, GM, puts out VINs in blocks. This does not make sense. How does a manufacturer know something that they did not do?? I would like my VIN added to the list of vehicles that are affected by this recall. Thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

BRAND NEW 2026 CHEVY TRAIL BOSS LT 6.2L V8. DROVE NORMALLY FOR 1291 MILES BEFORE THE ENGINE LOCKED UP AND VEHICLE DIED WHILE DRIVING. CHECK ENGINE LIGHT FLASHED A FEW TIMES BEFORE IT DIED. GLAD I WASNT TOWING ANYTHING YET. ONCE I COASTED TO A SAFE AREA, THE TRUCK WOULD NOT RESTART. DEALER SAID ITS THE ENGINE. NO ETA AS THEY ARE NOT AVAILABLE. VEHICLE SITTING AT THE DEALER WITH NO ETA ON PARTS. THIS IS A 2026 SO IT IS STILL UNDER POWERTRAIN WARRANTY AND NOT UNDER THE RECALL YET.

My vehicle is listed as not being affected by any current recalls. When I purchased my vehicle in December 2025, it did not have an Owner's Manual in the glovebox, which I found concerning. Why do I not qualify to receive something as important as the owner's manual under that current recall regarding that safety issue?
