2026 Chevrolet Silverado 1500 Transmission and drivetrain Problems

“While driving my truck returning from a camping trip I received the following warnings in the dash: Service ESC, Service traction control, forward collision system unavailable. Check engine light was flashing. I made the assumption that the Check engine light was due to the warnings listed above. I continued to drive the vehicle until I began to feel a very noticeable shudder at idle, at low speeds, and also loss of power at higher speeds. The truck has the 5.3 ecotec engine with DFM. …”

“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..”

“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. …”

“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. …”

“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.”
