ELECTRICAL SYSTEM, LANE DEPARTURE: WARNING, SEAT BELTS
The infotainment system loses all audio through the speakers intermittently. when this happens I also lose the Safety warning chimes as well. shutting off the vehicle for an extended period of time resets something and it resumes normal function. I have contacted GM customer service and spoke to 3 different representatives and requested an escalation to a Senior Advisor, which i was told could take up to 4 days to hear back. the vehicle has 800 miles and is 1 month old, this has occurred 4 times. it has not been looked at by the manufacturer as i am waiting for return communication. Other than no sound, everything else on the touch screen seemed to be working normal, but im no technician to determine that. i feel this is a safety concern as i travel with my 13 month old daily.

SERVICE BRAKES
The trailer brake system is displaying a warning. The truck has less than 50,000 miles and the tow option has never been used. I am told that it would be risky to use it without repair. this is a safety issue that should be a recall. I have checked and there are thousands with the same issue and it has gone on for years without being addressed by GM or NHTSA. It's time to step up and take care of this situation. There is no telling how many have been injured or killed by this. if nothing is done I will approach someone in the media.

SERVICE BRAKES
While parking I was backing up to straighten the truck in the space. When I went to stop I noticed that "normal" pedal pressure was not stopping the truck and I could tell vacuum was not available to boost the brakes, causing me to have to "stand on the pedal", almost causing me to hit the car behind me. I purchased the truck used four months ago and when checking recalls the nhtsa says none are open so I assume it has been addressed but didn't fix the issue obviously.

STRUCTURE:BODY, SUSPENSION, UNKNOWN OR OTHER
The main body frame is completely rusting through from under the drivers side door back past the fuel tank. It is rusting through on the passenger side as well. The large amounts of rust have caused other issues throughout the entire body of the truck as well as rusting of other components. The frame of this truck will need to be replaced as there is no way to repair it or the vehicle becomes scrap. This vehicle is available for inspection. These issues were not visible when purchased from the dealer. This issue gradually became visible after the rust and undercoating wore away that had been applied previous to our purchase from a known dealership.

AIR BAGS
Service Airbag light is on. Airbag removed and replaced at owner's expense. Diagnosed electrical concern. Cost Not covered by GMC. There has been four Airbag recalls on the 2016 GMC Sierra since 2016, but none covering total replacement of the Airbag. Recalls dated 09-08-2016, 07-10-2017, 11-25-2020, and 07-01-2021. Does NOT seem logical to me to cover cost for most of the component, but not the Airbag itself. This doesn't seem fair...$1422.45.

VISIBILITY/WIPER
17Jan2023. 2018 GMC Sierra 3500HD Denali. Northbound on I37 near Three Rivers, TX. Speed approx 75 mph. Temp approx 55F. Wx conditions, 1/2 mile vis in fog. Traffic, zero vehicles ahead, one vehicle approx 100 yards behind. Time approx 0815. No overpasses encountered. Cruise control engaged. My son and I were talking when we both heard a sound us above resembling ripping cloth lasting approx 1/2 second immediately followed by a loud explosion followed by the sound of fragmented clinking. The rush of wind noise followed as we could hear pieces of glass continue be taken by the slipstream. I was able to immediately deduce that the sunroof had catastrophically failed. I never use the sunroof or even open the slider so luckily it was closed as usual and no glass fell into the cab and no injuries were sustained. My son and I began to look around us while continuing down the highway to see if an object could've caused this. With no vehicles in a position to have flung a rock or other material and no overpasses in the area, we concluded it must've been a defect. I took the next exit and stopped in a gas station parking lot. We exited the truck and visually inspected the roof. The glass was indeed shattered. Further, the glass had appeared to failed outward as the remaining glass was directed away from the cab. There had been no prior indications of impending failure. There were no warning lights and the police were not called. Had a vehicle been close behind the outcome may have been worse as it would've been showered with debris. The vehicle is under warranty but GM has declined coverage, claiming it must've been a rock or something, even though that would've been impossible given the circumstances.

UNKNOWN OR OTHER
The radio in my truck acts on its own (buttons push by themselves). The problem is known and I’m fine with turning my radio off instead of paying a lot of money for a new one. I’ve been fine with it until recently. First problem I’ve let go for a while now which is that it turns on by itself while driving which is a distraction. But biggest problem now is not only did the radio turn on by itself but it also went into the backseat reminder and turned it off. I do have an infant and I hope to never forget. But when paying for a vehicle this is a feature you pay for. No one should lose a child bc of this. I’ve talk to a dealership about the initial problem and have done research on it. There is no warning signs. Vehicle has not been inspected by any others. I do have a video of the backseat reminder turning off without my control.

UNKNOWN OR OTHER
Just noticed that the Frame is rusting badly. It is available for inspection upon request. I see that the Chevy Silverado has the same problem and that a recall exists for it, but not for the GMC Sierra, which is virtually the same truck. My safety or the safety of others can be put at risk if the frame were to fail. The problem has not been reproduced or confirmed by a dealer or independent service center. The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. Unknown about any warning lamps, messages or other symptoms of the problem. No failure yet.

EXTERIOR LIGHTING
This vehicle has poor headlight performance. I changed the bulbs to no avail. There is no way this 2015 GMC passes vehicle state inspections if they really look. There is very little power to the lights, even on the high-beams. After some quick research - GM has a service bulletin PIT5374 that addresses this very issue. But the dealerships are using this safety defect as a way to generate service volume. Requiring a $170.00 diagnosis to identify a problem they already know exists.

BACK OVER PREVENTION: WARNINGS
Bought. New 2022 GMC HD 3500 last year and signed form from GMC saying front and rear parking sensors were delayed until December 2023, related to supply chain issues. I have continually tried to get a status of the needed micro chips and now have been told today that GMC has no status as they are focusing on the new vehicles so they can continue to sell vehicles and make profits. GMC knows this is an on going safety issue but continues to ignore vehicles already sold.
