Example complaints
Transmission and drivetrain: “This issue is pertaining to the valve body in my 10-speed transmission. While I was traveling home, the truck experienced a “wheel lockup”.

I have been without this truck for 3 months waiting on parts. This is absolutely unacceptable from gm. Extremely unsave.”
