POWER TRAIN
Called multiple dealerships and found out there is a known problem with the valve body for the transmission in these vehicles, which mine is currently being towed today to the dealer. This is what happened to me today, I was driving with my two children on the interstate and all of a sudden I had no drive nothing so the speed reduced quickly. Well behind me there was a 18 wheeler on my back and almost ran into me because I had no more drive on my pickup. Then when it was safe to pull to the side of the road found out there is no reverse either. Making it even more unsafe to drive these vehicles. If I need my reverse to back my vehicle out of on coming traffic’s I would not be able to do so. But this is the big kicker, this valve body for these vehicles are not being produced by gm. The multiple dealer ships that I called have said all the same thing, this is an extreme safety issue that should be recalled.

UNKNOWN OR OTHER
I bought this truck used, in 2022 for $24,000... had it put up on a lift and fully gone over before purchasing. Roughly 18 months later I was notified by the garage that there were some rust holes in the frame that needed to be fixed. I had those holes repaired in March 2024, and the vehicle was inspected. At this time I went over the entire frame and found no more trouble spots. I recently went to trade-in the vehicle to buy something smaller and the dealership told me the frame was "rotted" and that the truck was essentially worthless and actually dangerous to drive. These frames are rotting from the inside out, and go from a sellable and valuable truck, to worthless within months or years. GM used inferior steel, inferior rust prevention, and is leaving countless owners stranded with vehicles they cannot sell, are unsafe to drive, and are still paying on. I still owe $10,000 on the truck and the best offer I've gotten has been $3,000. My options are to either put thousands of dollars into the vehicle and pray the rest of the frame does not suffer the same fate (unlikely), or junk the truck and buy another vehicle, meaning I'd need to pay two car loans off and only have one usable vehicle. GM knew about this issue and did not fix it and now hard working Americans are being financially devastated because of it. I bought a nice, clean 8 year old truck, and 2.5 years/20k miles later I'm left with junk and a depreciation of roughly $1 per mile for the time I've owned this vehicle. This has been an extremely stressful situation which has left me coming to terms with the fact that I'm most likely losing $10,000 because of this frame issue. This truck brand new sold for over $42,000 and 10 years later is worth about $2,000, if that. It was not beat, or neglected - simply driven and used as intended. This is unacceptable.

ELECTRICAL SYSTEM
Service Trailer Brake System Warning From time to time, this warning goes off in the vehicle and when it does, it does it constantly. When the warning is dismissed, it does it again seconds later. If it is not dismissed, it does it again seconds later. It is a persistent three ding double chiming that is not only constant, the vehicle is doing it without a trailer connected to it. The GM dealerships we have been to regarding this issue do not know how to fix it since the warning is as intermittent as it is persistent. Once one of the dealerships was finally able to observe the warning themselves, we were told because it does not cause the check engine light to come on, they are not given a code, therefore, they do not know how to address the issue. The Service Engine Brake System warning is not only a persistent auditory nuisance. The warning chime overrides any other audio capability of the vehicle and it will be the only thing the control panel shows. If the warning is dismissed, it comes right back. This means we cannot hear anything else in the vehicle, such as turn signals, and we cannot see anything else on the control panel, such as speed. We can only surmise this issue is some sort of an electrical system malfunction since we do not have a trailer connected to the vehicle when the Service Trailer Brake System warning is coming on. The vehicle has been presenting this persistent warning since we purchased it from a dealership in August of 2022 and the vehicle continues to present this persistent warning intermittently, which will last days to weeks at a time and is not corrected by the engine being turned off and restarted, no matter if the engine is shut off for minutes or days. How much time passes between the persistent Service Engine Brake System warning events can be less than one day to several months later.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
While driving, my wife and I heard a bang, and when she went to turn her head, she noticed that the vehicle was smoking from rear defroster, and the back windshield had smashed. we immediately pulled over and the vehicle did not stop smoking until we turned off the rear defroster. This put our safety at risk as the entire vehicle could’ve caught fire. When we went to check to see if it had been recalled, Our vehicle did not have any open recalls But we found that there were many other GMC Sierra trucks with this issue. We contacted our local dealer who confirmed that he had seen this happen to other GMC Sierra trucks. There was no warning light Or other indicator that this was going to happen. Unfortunately, Our vehicle was not included under recall N192265660 and we strongly recommend that another investigation is performed to include all 2014 GMC Sierra trucks. I have a video showing our vehicle smoking with a smashed, sliding Back windshield.

The stereo turned all the way up and the sound buttons on the steering wheel plus the manual volume button were not responsive and it would not turn off. I turned the truck off and it still was on for 15 minutes. I turned it from Sirius XM to FM and then the volume worked but it hurt my ears and should never happen again.

STRUCTURE:BODY
I was driving down the highway at approximately 60 mph, and the upper front trim from above the grill flew off, struck, and cracked my windshield. Based on my research, this is a very common problem and a serious safety concern for drivers of 2022-2024 GMC Sierras. It is also a safety issue to the general public for anyone traveling or walking near this vehicle when this condition occurs. There was also an article published on gmauthority website about this common issue as well as multiple Reddit posts and GM Forums.

ENGINE
While driving my 2023 GMC Sierra 1500 Denali, 6.2-liter engine on the highway, the engine seized at 22,000 miles. GMC has been working on my truck since 9/7/24 and still no truck. The end state is, I was told by the Service Department that there is a design flaw with the 6.2-liter engine (something with the intakes valves being too large, resulting in the valve bending seizing the engine). I was also told, this dealer had two other trucks there now with the same seized engine. Their plan is to install a new engine with the same design flaw with the hopes it does not happen again. This was an extremely unsafe condition as I was travelling at 65 miles per hour on the highway when the engine seized, luckily, I was able to coast to a large shoulder after almost getting into an accident when it seized going uphill.
