TCM and electrical transmission grounded out TCM IN MY RESEARCH a lot of people are having issues with these. Dealers are of no help “backordered” so having to rebuild them. This is an expensive failure!

The recall is with the steering wheel air bag. If it goes off then the driver could possibly get injured or killed from metal fragments according to the recall letter that I received. The letter is dated June 10, 2023. If they can't come up with a fix then they should supply me with a vehicle that is safe. Seven months is way too long.

The door locks began to have issues; the locks started to work only occassionally for no apparent reason. I've been locked out of the car several times and had to use the auxiliary key. Plus I couldn't lock the car while I was inside as the interior door lock button wouldn't lock or unlock the doors either. It's not a kefob or battery issue and no lights on the dashboard. The dealer reports that they couldn't reproduce the issue. However they found corrision on the electrical harness inside the passenger front door. I replaced an electrical harness in the rear bumper 18 months prior for corrision found. The dealer says they received a service bulletin on the "electrical harness" issue however the dealer won't cover the cost of $500 to replace the harness. As this deals with the electrical system, my concern is that it may effect the operation of other components of the car while it's running. Safety and security is of the utmost importance whether at home or away as it regards to being able to lock or unlock the doors.

Transmission developed shutter/shimmy when shifting gears especially at lower speeds. Took truck to dealer and they diagnosed that the torque converter had failed. There are numerous reports and complaints online regarding this issue with GMC Canyons.

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 manufacturer was notified of the failure. The failure mileage was 39,106.

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.
