What owners report
6.2 liter engine failed at 59,300 miles. Being replaced right now with remanufactured engine. 2020 GMC Sierra is not part of recall but others have had problems as well
I own a 2020 GMC sierra AT4. It has developed a shudder when cruising on the highway or driving in town around 1500rpm. I believe it is coming from the transmission. A local shop mentioned the torque converter. The shudder feels like a delay in power and makes it difficult to hold speed or accelerate when needed.
This morning it seems as if my 6.2L GM motor threw a rod. All the initial sounds and check engine information point toward that. I will be taking it to a dealer to confirm the issue. Data center driving ability and sounds indicate steering was affected as well or is somehow connected.
Transmission control valve real,rear wheels can lock up causing accident recall # 26V083000
I was driving and my truck shut down on me while I was driving down the road, I had to get it towed to the dealership where it was confirmed that the motor would need to be replaced. There was no warning, it just turned off and luckily I was able to coast to a safe area to wait for the tow truck.
