SERVICE BRAKES, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
My truck 2020 gmc sierra 1500 AT4 denali is not working properly since July 2024. I took it to 2 different dealership to get a diagnostic and i finally ended doing the repairs for brake issues. I have been towed 6 or more times and almost experienced 2 car accidents since I drive the truck after the supposedly repairs where done but i ended stranded again with no brakes. The dealership has repair the truck 3 times but im still getting sevaral codes the fact that i had to pay out of pocket and have to deal with this and expose myself to danger and my family in driving a vehicle that is no safety condition its absurd. I call several times the recall GM hotline and i was told GMC 1500 are included in the recalls just not the AT4 and i have a family member with the same truck and same issues she ended up trading in the truck recently since she kept experiencing the same issues over and over again just like me.

STEERING, WHEELS
since new there is a violent vibration in the steering wheel and floor boards. steering wheel oscillates side to side at speed from 38mph to very bad at 65mph. Dealer has had it 5 times and still cant fix it. they state the front hub extensions are out of round and have tried 3 sets without any success. this truck is not safe to drive as it will put your hands to sleep due to the vibration. Also it will cause premature system component failure. the GM forum and Duramax forum is showing many cases nation wide with this symptom. Also there is NO provision with the current 18 inch wheel to index concentrically with the mating hubs on all four wheel locations This is mainly affection the Dually wheel Denali or high-country vehicles

STRUCTURE:BODY
A large trim piece at the top of my grill flew off while driving 70+ on the highway. I have personally seen roughly 100 testimonies with picture proof on various fb pages of others with the same vehicle experiencing the same thing. This is a known issue for the 2022-2023 model years, GM has apparently corrected the issue for the 24+ model years.

STRUCTURE:BODY
My GMC which is well cared for and only has 121,000 miles has a rusted through frame (mid-vehicle, left side) which has made the truck unsafe to drive. The steel used is inferior, my neighbor across the street also has this truck, 2 years newer, and is doing the same thing. As I have researched this issue I have found out that this is a critical failure of the GMC Sierra for several model years due to a failure to protect the steel used in northern states which compromises structural integrity. When Toyota had this issue, they stepped up and replaced the frames. General Motors, please tell me what you intend to do with this. It is a 5.3 Litre with 121,000 miles on it, in other words, still a baby for such a fine engine. This is not right. I am seriously discouraged. For my family, this is devastating. I still owe $2000 on this vehicle. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, POWER TRAIN
In the past 6 years I have owned 4 GMC 6.2L trucks the first was a 2019 no issues great truck. The second unfortunately had a Short life with another vehicle. In 2023 The third a 2021 Denali 6.2L truck at 34k began using oil and blowing blue smoke out the tailpipes. The dealer started an oil consumption test (like you couldn’t see it happening) so finally at 45k they tore down the engine and found worn out valve guides and scored cylinders. They ordered an engine the engine was installed and it failed in 25 miles come to find out it was not oiling on one bank, A second motor was ordered and installed it failed at start up. At this time it had been months that the truck was down. The dealer took a stand and moved me into a 2022 GMC AT4 with 6.2L with the hopes of removing the issue this truck was the internet sales managers truck that he had recently bought and had 15k on. We made the deal, well at 35k this truck begins consuming oil. The dealer once again starts the oil consumption test process. A couple of months ago. The truck now has 42k or so on it and on my last trip from Atlanta to Fort Walton after the dealer just topped it off 2 1/2 weeks prior to the first 2500 interval of the oil consumption test, the truck burned 1 1/2quarts in less than 2k miles and the oil warning light comes on as we arrive in Fort Walton. I would like a resolution to this, I have invested a lot of money into what should be one of the most reliable trucks on the road and all I hear is GM says it’s not met their threshold of a problem and you should expect to have to add oil to a truck with less than 45k on it and it’s not a problem. It’s already been proven with the 2021 that GM has a problem, I as well as the other 100,000 or so individuals with this same engine and GM knows it’s a problem with the quality of the engine build. GM has a quality issue and knows it but they are not addressing it, just making the consumer jump through hoops and not finding a fix in 5 yr's is bad
