The rear back glass is leaking water excessively in to the inside of the vehicle when it rains or gets washed. The vehicle is available at any time for inspection. The amount of condensation that accumulates on all the interior windows makes it impossible to see out of the vehicle. The defrost can not handle the amount of moisture build up. The Dealer knows about this condition and it has been verified by a window company. The manufacture knows and understands there is a problem and has put out a Technical Service Bulletin ( TSB 18-?'NA-?'383 ) for this issue but will not cover the repairs. GM knows that every single vehicle with this window designs from 2019-20121 will leak just outside the 3 year 36k mile warranty coverage. The cost of repair is approximately $2k. Dealer will not cover repair.

Back window frame crack led to water intrusion which flooded electric module controlling speedometer and adaptive settings. Extremely unsafe driving with faulty electrical components unknown to me. Insurance and Dealership told me this is a common GMC occurrence. Cost is near $10,000 to make truck drivable.

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.

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.

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..

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.

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.
