“I am on my third 6.2L engine at 80k miles due to engine failure. It is absolutely ridiculous and is a safety issue for sure. It has left me stranded twice. And now GM is giving me a hard time about not wanting to cover it under warranty.”
“Major engine failure with substantial loss of power while towing 24ft camp trailer. New engine has been installed. I was told by dealership that it was failure of engine bearings and connecting rods. They had seen a few similar cases”
