STEERING
The vehicle has had steering and alignment issues since the day I purchased the truck. The steering wheel is not centered. The steering wheel is always turned to the left but the vehicle pulls to the right. I have had it at my local dealership five times and they have confirmed what I have described but they are not able to fix the issue fully. They have rotated the tires 3 times and have aligned it all five times. The vehicle will be good for about 100 miles and will go out of alignment again. The dealership explained to me that they are experiencing this with all 2024 Chevy and GMC heavy duty trucks. The vehicle is very difficult to keep straight especially at higher speeds on the interstate. I am part of a 2024 Chevy and GMC owners facebook page and hundreds of consumers are complaining of the same issue.

TIRES, TIRES:TREAD/BELT
I was travelling south bound on the highway at 70 mph when out of no where the left rear tire failed. The tread peeled back like an alligator skin and tore apart the side of my truck and caused me to fishtail all over the highway. I was able to avoid colliding with other vehicles on the road and miraculously made it to the shoulder of the highway. The tire is a Goodyear Wrangler TrailRunner AT in a size LT275/65/R20. I still have the remaining parts of the tire. My vehicle is still under manufacturer warranty, but the GMC dealer turned me away and told me I had to deal with Goodyear directly. I reached out to Goodyear to file a claim for the tire failure and damages related to it. They have been ignoring me for over a week, so I have filed a claim with my insurance company to handle the damages. I'm currently waiting to get my truck into the shop for repairs. There were no indications of any issues with the tire. I had them rotated as recommended by the manufacturer and kept the tire pressure at the recommended levels through the dealer when my vehicle was serviced. The TPMS light came on as soon as the tire failed and lost pressure showing the vehicle tire pressure monitoring system was working properly when the tire failed.

UNKNOWN OR OTHER
This complaint is about General Motors not allowing their Dealer Marty's Chevrolet of Bourne Ma. to recalibrate the odometer and speedometer and other parameters in the computer to match new 18"wheels and tires. The truck was built and set up for 20" wheels from the Factory. The previous owner installed 22" wheels immediately after leasing the vehicle. They never adjusted the computer for this change and as a result the odometer reading read 28700 when I purchased it in August 2023. As a result the engine hours do not correlate to the low miles and the speedometer reading is incorrect. This truck has about 75 to 80 thousand actual miles. When Marty's installed the new wheels that I bought, GM refused to authorize the computer adjustments for the new wheels. GM previously required this adjustment, but no longer does it. This is a safety risk and actual fraud because of the inaccurate miles recorded. I hope you can require them to authorize this adjustment.Attached is an old instruction from GM to dealers for this wheel size change work order.

Transmission shakes constantly not just when shifting. Repair shop says this is not repairable and is a common issue in trucks like mine. 2016 GMC Sierra. Vibrations are significant enough to cause a safety issue. Getting worse with time.

SERVICE BRAKES, VEHICLE SPEED CONTROL, ENGINE
Rainy road, 60mph on the hw with my family. Truck decides to engage stabilitrak or something to that feel and locked up the brakes. Talk about a scary moment with an 18 wheeler coming in hot behind you. Obviously, in the moment, I had no clue what was happening other than something with the truck was malfunctioning. This scenario could have gone wrong in so many ways. I'm honestly in shock someone has not been killed because of this?

The truck has only 122, 230 miles and shuddering in the transmission is horrible. I just purchased the truck 3 weeks ago and the owner stated nothing was wrong with it. However I took it to mechanic for inspection after purchase and he stated transmission has shuddering. I noticed at 40 miles plus the truck vibrates at steering wheel.

SERVICE BRAKES
Towing an RV with solar panels. When the trailer battery becomes fully charged and has a higher charge than the vehicle battery, the trailer brake control module becomes disabled. When this occurs, you have no trailer brakes. Combined weight of truck and RV exceeds 20,000 pounds. Trying to stop with only truck brakes is dangerous, especially if you are on a decent. I not only believe this to be a safety issues, but somebody is going to get killed.

STRUCTURE:BODY, SUSPENSION
I went to get the vehicle inspected today and was told it failed due to the chassis frame in the rear being rusted thru. This could cause the suspension to collapse any time. I see on the internet that multiple others have and are experiencing the same with the Sierra and Silverado. My vehicle has unlimited washes and has been washed 40 times a year and looks new from the outside.

Tailgate opens by itself, a know issue by GM and Sierra drivers. Mine was damaged by opening and banging against my travel trailer. I have been talking with GM about this since September. Today a different department told me they require up to 30 days to investigate and if I pay for the repairs myself they will cancel the investigation. Objects flying out of my pickup bed could damage my vehicle, my camper and others on the road.

ELECTRICAL SYSTEM
My 2021 GMC 1/2 Serria SLT 4x4 Crew Cab short bed, V-8 Gas engine with Automatic Transmission. I bought this pickup used with apprx. 41k miles on it. I had it about 2 months when I went out to start it and the battery was completely discharged, it would not even click or any lights come on. I hooked it up to a battery charger and got it started, took it to a shop and had the battery and alternator check which both were ok. Drove back home and went out the next morning and the battery was completely drained again, got it started and went an put in a new battery. 16 days later it did the same thing this time it smelled like wires burning when I opened the hood. Called the dealer I bought it from and they put it on a diagnostic machine for over 3 hours could not find anything. Then next morning the battery was again completely drained. Got it started and took it to another shop to get it checked out and after almost 3 hours there they found nothing. Came back home an it sat for just over 40 hours and again the battery was completely drained. I could smell what I think is plastic or rubber when I opened the hood again. My main concern is that this may be a fire hazard and could not only burn up my pick up but my house as well. The check engine light has came on but goes off so I am at a complete loss on this and seems as if GM is not concerned either. I have tried contacting GM but so far nothing other than a note from GM Canada that I need to contact the GM USA, and again that is the only thing I have gotten from anyone. Perhaps this is just a odd thing, I don't know but I do know it is not a safe thing.

ENGINE
Lifter Failure: I was traveling to a State Park in Northern Michigan when my engine starting running very rough with major power loss. My check engine light activated, and I pulled over as soon as I could. It was dangerous because I was pulling a camper and I had to drive well under the speed limit. The Certified Chevy Dealership discovered a collapsed lifter and Cam damage. They considered this as catastrophic engine failure, and I was completely shocked as the vehicle had roughly 129k miles on it. There was no indication of failure prior to this incident as the vehicle ran perfect. I am very disappointed in GM as I have a co-worker with the same year truck that had the exact same issue shortly after I did. A friend of mine also had this happen with a 2014 vehicle of same make and model. It appears that this is a common issue with GM's newer 5.3 engines which used to be extremely reliable (99-07). GM needs to fix these lifter issues because a newer technology engine should last much longer.
