While driving vehicle with infotainment system playing radio, radio volume goes to full volume that is ear piercing and is going to cause hearing damage. Must pull off the road as fast as possible, place vehicle in park, shut off vehicle and open drivers side door to get radio to shut off. While the issue is happening volume knob does nothing, stereo on off button does nothing and steering wheel volume controls do nothing. This is a serious issue when trying to pull over, I keep ear muffs in vehicle to protect ear drums. This has happened at least 6 times, I plan on bring to GMC dealer.

The car consumes oil to the point there's no oil in the engine. Not a result of a leak but rather the engine is actually burning it. I've taken it to 4 dealers, all confirmed it's due to Kia's bad engine design & that there's no visible leak anywhere. The kia dealer also confirmed there is no oil level sensor but only an oil pressure sensor. According to the dealer, I don't qualify for a new engine until the check engine light turns on or the vehicle results in a fire. I have to get the oil topped off every 500 miles. I don't feel safe driving this vehicle. The dealership also states I'm no longer covered under the warranty as I'm a 3rd owner. My coverage ends at 60,000. I was not aware of this during purchase of the vehicle back in 2020.

Tailgate inadvertently opens. There is no visual or audible alarm to inform me the rear tailgate is open. This is a Denali package truck. I have lost items, coolers, small folding tables among small items without warning. Most of the time I was traveling on a highway. Could cause accidents, injury to others as well as I have lost my belongings. I have had the dealership as well as 2 requests with GM customer service with no corrective results. The trucks tailgate will show an open display warning but only when top tailgate is down/open. If the whole tailgate is down/open there is no visual warning on dash. I believe there was an error in placement of open tailgate sensor when truck was produced. 2023 models have correct sensor placement and visual dash warning. The 2022 was a new redesign doe the Sierra class truck and there was a mistake where the open tailgate sensor was placed. I went to GMC virtual site and the 2023 model examined by GMC employee on visual check shows on complete tail gate down/open the same dash visual tail gate open alarm I see on my 2022 when only the top part of whole tailgate is open. My Dealership and GMC customer service have been involved for the past year. I have been reimbursed by GMC for my losses but problem still exists.

Driving on state highway at posted speed. A deer ran into the right front and side of vehicle. Side airbags deployed. When the right side airbag deployed, it burned a hole in my passengers winter coat that completely went through the right sleeve forearm and scorched the sweatshirt that she was wearing under the coat. Smoke was visibly apparent in the cab of the vehicle. We thought the truck was on fire , then finally determined it was the sleeve of here coat.

Rear half of Frame Crossmembers rotted away between the Frame rails. Took vehicle in for routine safety inspection, and the mechanic determined that the cross members to which the rear shocks and the Gas tank were attached had both broken free from the frame rails due to rust. The entire back end of the vehicle is suspended from the frame with only the leaf spring mounts. This rust is excessive and far exceeds the rust on other points on the frame and undercarriage of the vehicle.

My 2017 GMC Sierra 1500 Denali started shaking violently and the rpm gage began bouncing 1/4 to 1/2 inch in a very short amount of time. I ran a maintenance facility in Europe with 317 local national and 25 U.S. employees. Two of my brother-in-laws, and one of my nephews are mechanics. Two run their own auto repair facilities. All three reported having to replace torque converters on multiple gmc/chevrolet 1500 trucks. Many at somewhere between 40 and 60 thousand miles. If this is such a systematic problem, and from the number of vehicles they have had to repair it is, why hasn't a recall been issued. Second, in most cases dealerships first charge excessively for replacing the transmission fluid (approximately $900) and then end up replacing the torque converter. The owner has to pay for the transfluid replacement out of pocket because it is considered maintenance instead of replacing the torque converter at company expense...especially if you purchased and extended warranty through a third party. If this is recalled, owners should be reimbursed if they had to pay for it themselves and they should be required to replace the transmission fluid filter as a part of the repair,

The rear window was leaking a substantial amount of water soaking the back seat. Had the service bulletin done, which did not work. Then under further inspection found cracks in the rear power window track. Dealer told me GM would not cover replacement because it was out of the 3 year warranty. Then was told it would cost me 1200 dollars to replace. GM should cover this because it will lead to black mold.
