Owner-reported complaints naming the body or structure system, filed with NHTSA

Data refreshed

Body & structure reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Rear sliding glass window is leaking water around the exterior frame. This is addressed in TSB 18-NA-383 but not covered under any warranty. My rear seats and carpet are becoming wet. I am concerned about the possibility of mold and an electrical short/fire resulting from water intrusion. There are many reports and discussions on the internet regarding this issue. Full window replacement estimated at $1300. Patchwork repair with caulk is estimated at $600 with no guarantees of success. I would expect GMC to cover the replacement of the rear glass in kind and remedy any other damage to my vehicle due to water intrusion into the cabin area.

My tailgate has been unlatching while driving and I do not understand why. It came down while I had my trailer attached and it damaged the tailgate. No one is touching the button that unlatches the tailgate and it is closed when I start driving, but sometime before I arrive to the next destination it's miraculously down. This is very dangerous and I would like help getting it taken care of

The rear window on the 2019 GMC Sierra SLT leaks water into the cab. This presents a serious concern to the owner of the vehicle because unless you are specifically looking for the leak you may not even know there is one. Upon noticing the leak, one can witness a steady drip of water behind the rear seat, drivers side. My personal concern is that what happens after the water has leaked and had gone unnoticed for an extended period of time, does mold start to grow? Does my truck have mold growing in it? With two young children in the vehicle I am concerned about their health and safety. My frustration with this issue is that GM refuses to acknowledge that there is an issue. My dealer has brought this issue up with GM but the claim has been denied. I have no idea how long the leak has been happening but it’s a manufacturing problem that exists and it certainly shouldn't be the owners responsibility to fix the problem. More importantly, it shouldn't be my young childrens health that is affected by the manufacturers incompetency and ignorance.

FIRST WEEK OF OWNERSHIP I NOTICED THAT THE REAR WINDOW HAD A WATER LEAK BY REAR DRIVER SEAT. WHILE INSPECTING THE LEAK, I NOTICE THAT THE PAINT ON THE REAR BRAKE SPOILER ABOVE THE REAR WINDOW HAD TWO BLACK MARKS. BODY SHOP TECHNICIAN RUBBED HIS FINGERS ON THE SPOTS AND PAINT WAS RUBBING OFF. I STARTED TO RECEIVE 'SERVICE STEERING COLUMN LOCK' MESSAGES INTERMITTENTLY AND REGULARLY DURING STARTUP. HEATING INDICATOR LIGHTS FOR ALL THE SEATS DO NOT LIGHT UP TO INDICATE THEIR SETTINGS. THIS OCCURS WHILE VEHICLE IS STATIONARY OR ON THE ROAD. THE REAR BACKUP CAMERA SCREEN TURNS BLUE AND DISPLAYS 'SERVICE REAR BACKUP CAMERA' WHILE REVERSING AND IT OCCURS OCCASIONALLY.
