Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Back up camera is awful at night. This is a safety issue because you cannot see anything when backing up. My truck has 323 miles on it and I went to dealership they said I would have to live with it. That is not acceptable to have a safety feature that is faulty.”
NHTSA complaint #11362024, filed 2020-09, 323 miles“While driving on a state highway, I heard a pop sound, I saw nothing contact the vehicle, but I then noticed the windshield was cracked. The windshield cracked for no apparent reason..”
NHTSA complaint #11396371, filed 2021-02, 27,540 miles“Wipers froze to windshield while driving with defroster on max. Design of the windshield and dash means wipers sit lower than where the dash and windshield meet, and no warm air from the defroster can get to the windshield where the wipers sit. There is no in window defroster (like rear window) which can help. Major safety issue in snow/ice conditions.”
NHTSA complaint #11390959, filed 2021-02, 5,400 miles“The rear window was leaking a substantial amount of water soaking the back seat. Had the service bulletin done, which did not work. Then under further inspection found cracks in the rear power window track. Dealer told me GM would not cover replacement because it was out of the 3 year warranty. Then was told it would cost me 1200 dollars to replace. GM should cover this because it will lead to black mold.”
NHTSA complaint #11560834, filed 2023-12“The rear window on this vehicle is leaking water and has been for some time. It has become quite bad and is causing an odor and discoloration in the carpet. I could not find the cause of the problem until recently with the plastic cracking more. The vehicle has 41,000 miles and the dealer stated that is out of warranty and all repairs would be a cost to me. I researched this and have found it is a common fault this this vehicle.”
