8 Speed transmission slipped as I was going around a corner causing my 2017 Colorado stop suddenly causing the cars behind my to swerve to avoid me. Then the excellerator linkage or something caused the engine to rev out of control when the transmission finally stopped slipping causing me to run the truck off the road. This slip and then uncontrolable exeleration has occured 3 times since I bought it, This truck is a LEMON!
