STRUCTURE:BODY
I was driving down the highway at 65 when the upper front hood molding flew off and bounced off my windshield. There were motorcycles behind me but none were hit. After researching on [XXX] , many others have had the same thing happen. This could have broken my windshield, or worse, hit a motorcyclist behind me causing a wreck. It has not been inspected but reported by many others on GMC forums. There was no warning whatsoever. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM
While driving, I turned the volume on the radio a couple clicks louder using the steering wheel controls. After I stopped pushing the volume button on the steering wheel, it continued to rapidly increase volume until it maxed out. It was incredibly loud, in a panic, I verified the VOL+ button was not stuck. The VOL- on the steering wheel did not reduce the volume. I spun the volume button down, on the radio, but it would instantly return to full volume the moment I stopped spinning it. The power button on the radio also had no effect. I was driving at 50mph and had no way to reduce the volume from the max, which was incredibly distracting to say the least. I was finally able to get it to stop by pulling out my phone (which was connected via CarPlay) and hitting the pause button on my phone. Afterwards it behaved as normal, but my man did my ears hurt. Luckily there wasn’t any traffic nearby as I could hardly focus on the road while fumbling with the audio.

ENGINE, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
On June 8th I started my truck and it made a strange unfamiliar noise before starting. I thought it was bizarre. Shortly after I stopped in traffic and my truck stalled out. It stayed on but when I went to give it gas I didn’t move. So I restarted the engine and the same strange noise was made. Along with the noise I smelled something funny so I pulled into a gas station. Little did I know my truck was on fire. I got the vehicle away from the gas pumps and within 5 minutes the whole truck was on fire. Before this fire I had brought the vehicle in for service due to a check engine light multiple times the codes will be listed below. I also had an interlock device installed in the truck at the time.

SERVICE BRAKES, ELECTRICAL SYSTEM
Encountering trailer brake issue where the brakes on our 5th wheel do not activate via the GMC Trailer Brake control module. Have just had it replaced and still experiencing the same issue where it posts an alert on the screen multiple times and does not activate brakes on trailer. This is a widely known issue with GMC trucks and the trailer brake that has been outstanding for over 3 years now and is a safety issue as there doesn't appear to be a fix from any dealerships or GMC. GMC has not taking adequate accountability for this issue. I'm looking at putting together a class action lawsuit with several other customers having the same issue. We are fed up with the inaction and falsely advertised towing package as we are unable to safely tow anything with their trucks.

ENGINE
Just got off the highway was at stop sign on exit ramp and it just died. No warnings no lights no indication that something was about to happen. No neutral so couldn’t even push it out of the way of traffic. Had it towed to shop for diagnostic. Possible lifter problem. $600. Dealership towed it to their shop. Engine tear down, lifters replaced. Gmc to pay 30%, dealership paying $1000, me $1300. Dealership started truck and the crank bearing spun. Now needs new engine, which are on back order. Cost ??? How long before engine available??? This is a known problem by the dealerships, GM & repair shops. Had we still been on the highway when this occurred doing 75mph we could have been killed.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
While driving the truck began switching between towing, normal, and off-road driving modes. Lights were flickering and various messages were being displayed on the dash cluster screen. After parking truck and shutting it off all of the lights were flickering and I was unable to start the truck. Charging the batteries did nothing nor was I able to jumpstart the truck with another diesel. After repairs for these issues, at some point the odometer reset and while likely not certain it reset to zero. GM has no way of knowing when it reset and how many miles were driven between leaving the dealership and the reset leaving me with a truck set to the best guess mileage. I am being told this was a software bug and having experienced another software bug when I had the recall to enable seat warmers where the keyfobs would not work in any way I have serious concerns about the quality and safety of the software on these trucks.

While driving, the infotainment system will suddenly increase volume to 100%. Have had this happen 4 times. Unable to turn sound down the last instance (or turn it off). Was able to find a safe spot to park and turn the vehicle off. This did nothing, as the radio would not turn off regardless of what I had done. After roughly 5 minutes of the vehicle being shut off, the radio finally turned off. No matter how many times the truck was turned on and off, the issue persisted. The only "fix" that worked was to let the vehicle for some time, which seemed to reset the system. THIS IS A MAJOR HAZARD AS HAVING SUDDEN SHOCK FROM VOLUME ISSUES IS EXTREMELY DANGEROUS. The sudden increase in volume nearly caused an accident on the road (each time). Vehicle is being brought to a dealer today to figure out the issue, but I see that it has been reported in several forums online with no fixes appearing to be available. Prior to the issue, there was no other issues or prior symptoms to alert of an issue.

SERVICE BRAKES
Hello, I purchased a 2022 GMC Sierra AT4 2500 in August of 2022. I then purchased a 2022 Alliance Avenue 30RLS in September of 2022. The first time we took the Alliance Avenue out on a camping trip (October 2022), we had brake controller issues. The brake controller would suddenly disconnect and I would have an error on the screen saying that the controller was no longer connected, and the light would go off on the brake controller on the dashboard. At this point, we had no trailer brakes. This issue happened several times, and the controller would go offline and come back, sometimes within seconds, sometimes in minutes (up to 10+). Strangely, the lights and signals continued to work. After the trip, I brought the trailer back to our RV dealership where they inspected the brakes and said we were okay on that end. I then took the truck to a GMC Dealership who informed me that everything was good on their end... Next trip, same issue. Took the trailer to the RV dealership and they took the system down to the brake pads and said they didn't see anything, but they rerouted some brake wiring just in case. On the way home from the RV dealership, the brake controller continued to fail. Took the truck back to GMC, they found nothing. Had a 3rd party RV repair tech install a solar shutoff switch and replace the trailer side brake plug in pigtail to rule that out. The issue persisted. Took the truck to a Chevy Dealership, the found no issues. Took the trailer camping several times, same issue persisted, and we were in dangerous situations over the Colorado Mountains, having this fail multiple times over Eisenhower Pass and other mountain passes. Took the trailer back to the RV Dealership, they found nothing - took it to the Chevy Dealership, they replaced the truck bed plug-in. The issue persisted. The Chevy Dealership informed me there was a module replacement for the GMC 2500 2023-2024 trucks, but they could not do that for me.

STRUCTURE:BODY
When traveling out of town on the interstate approximately 70/75mph. Part of our hood/trimming deluged scraping our hood and nearly Colliding with two other vehicles. Not something that is common and seems to me a manufacture defect that GM is trying to wipe their hands of and I will not stand for that. I have been trying for about a month to get GM to repair this odd phenomenon. However they continue to give me the complete run around. It’s been absolutely impossible to get a hold of anybody the dealership will not help me. I keep receiving email from Gm saying they attempted to make contact but, I did not answer my phone. I have my phone on me at all times I have received no voicemails from them. I write and called them back. I haven’t received a return call/voicemails, or email. GM originally refer me back to the dealership when the dealership will not help me. They originally said they will order the part. I have to pay for the part and they will pay for labor. They contacted me when they had the part in hand supposedly. I sat at the dealership for three hours today for them to tell me that part was not correct and that they can’t cover it and that I would need to cover it , I am tired of the games and I want my vehicle fixed. I have been left with no choice but to file complaint.
