Example complaints
Transmission and drivetrain: “The valve body in the ten speed transmission failed while driving. The transmission did a rough shift and a message popped up on the display saying that power has been reduced along with the check engine light illuminating. The transmission reduced usable gears to prevent damage. I was a hazard on the road way due to not being able to get up to the posted speed limit. The car is at Harvey Cadillac (the dealership I purchased the car from) and I have been told GM is going to replace the transmission under warranty.”
