The plastic upper rail glass guide frame on the rear sliding window assembly of my 2023 GMC Sierra developed structural micro-cracks during normal vehicle operation. This manufacturing defect is a known issue tracked internally by the manufacturer under Technical Service Bulletin (TSB) #18-NA-383.This structural failure allows severe water intrusion into the passenger cabin. The leaking water runs straight down the inside back wall of the cab, completely flooding and corroding sensitive, factory-installed electronic safety modules mounted directly beneath the leak path.This continuous water intrusion caused the catastrophic electrical failure and corrosion of the video processing control module located behind the rear seat. …
The tailgate on my truck opened while I was driving and I was unaware until I got to my destination. I had a utility trailer attached at the time and my tailgate was damaged from the jack on the trailer. I thought maybe I didn't latch the tailgate but it has been several days since I opened it. The following day the tailgate dropped two more times in less than a mile. I see there is a service bulletin and recall on most GM models but my truck is not included. I made a service appointment at my local dealership for them to inspect. The service writer already stated that my truck has no open recalls. I feel this is a safety issue first and second my truck has body damage. I use my truck as a truck and usually have stuff in the bed. My truck is completely stock with no modifications except a GMC bed cover that I purchased at the dealership. …
Whilst driving down the highway at 65 mph the plastic front grill deflector broke off and slammed into my windshield and the vehicle behind me. Luckily the vehicle behind me sustained no damage other than how frightened she and her children were. This is a known issue and was subject to a recall for the 2022 GMC Sierra Denali's. Nothing has changed between the 2 models as far as I can tell and it's the exact same grill deflector. When I informed the dealership of this they told me it would be a $950 repair out of pocket. First of all, it is unacceptable for a $75,000 vehicle to have a plastic component that can just break off and become an immediate and unavoidable hazard on the highways. The recall MUST be extended to these vehicles. I have reached out to GM and they confirmed it would be an out of pocket expense, but I am escalating the situation. Thank you!
