I am constantly getting a “shift to park” warning after putting my car in park. My car sometimes will not shut off because of this. It’s a safety issue for me because the car is not registering that it’s in park and my battery could very well die while I’m out with my children. This is a common complaint from what I’ve researched and needs to be fixed by GMC.

While parking, cannot turn off the vehicle because of a warning to shift the transmission to park, even though the shifting mechanism is in the park position. Happens very frequently where sometimes up to 10 minutes trying over and over to safely park the car. Has been happening for all of 2024 but getting increasingly more difficult to park.

AIR BAGS
Safety Restraint System Service light alert comes on at start up. I purchased this vehicle july 20th and returned vehicle to dealer for service on sept.5. I was informed the steering wheel air bag and coil are faulty. The repair parts are on back order and would take at least 5-6 months to get. I contacted GM customer service and was told the air bag system should still function according to GM. I have had this vehicle @ 2months, I don't feel comfortable letting my wife drive this vehicle or transporting my grandkids in it.

FUEL/PROPULSION SYSTEM
Once again (for the second time in a few months) the vehicle put me and my passenger in an extremely dangerous situation. We were driving down a 55mph country highway catching speed, somewhere around 45-50 mph and the car jerked so violently that it shook us even though we had our seat belts on. It then made a weird noise and felt like it was powering down so I stepped on the accelerator to try to bring it back up to speed and it sped up a little bit, jerked again (not as violently) and turned off. Luckily, since it was a country hwy and no cars were coming, I was able to coast into a driveway. I attempted to restart the car to turn around and go home but as soon as i put it in gear, it would shut off. I tried a few times and it would make a "tick tick, tick" sound but not start. I waited a few minutes and tried again and was able to get it to start, go in reverse and get back home. Once I got home it would not start again. Mechanic says it is the same issue and before, which was also part of a recall for this vehicle having to do with the fuel pump relay. I will be trying to tow this vehicle to the dealership for repair.

TIRES:SIDEWALL
After roughly 7000 miles of use the 235/55R20 102V Goodyear Assurance Weatherready tire has a bulge in the sidewall. There are no scuffs or scars on the tire to indicate an impact caused the bulge, it appears there is some sort of separation within the layers of the sidewall. I asked a Goodyear retailer to inspect the tire and they said it's automatically considered impact damage if the bulge is in the sidewall and Goodyear would not warrant such damage even though there is no evidence such as cuts, scuffs or scars. The tire inflation is to manufacturer's specifications and the tire isn't loosing pressure. DOT 1M78AJA5R purchased Oct 22, 2023 date code 3622

POWER TRAIN, WHEELS
The check engine light came on 12/2023. The vehicle was taken to Pep Boys and AutoZone in MD, WalMart and O'Rilley in Bastrop, LA, O'Rilley in Midlothian, TX. They could not find any problems with the vehicle. I took the vehicle to GMC in Plano, TX. THey charged me for a new battery but the check engine light remained on after I picked up the vehicle with a newly installed battery. The dealership said it would eventually go off. I took the car to Automotive Solutions in September 2024 and they can not find anything wrong with the vehicle. The car can not pass Texas inspection with a check engine light on. There is a large group on FB having this same problem. August 2024 the car will recognize when it is shifted into park. Sometimes it rolls after puting the car in park.I took the car to Automotive Soulutions in September 2024 and they can not find anything wrong with the vehicle. There is a large group on FB having this same problem. I took the car into a GMC dealership in MA because i hit a curb in 2021. The steering wheel feels loose. I took the car in 2022 & 2023 for the same problem. The dealership charges me for repairs but there is a reoccurring steering problem. Other drivers have noticed this problem with my vehicle.

When I shifted to Park and hit the button to turn the car off, it continuously chimed and flashed the Shift to Park message on the dashboard. It would not allow me to fully turn off the car, stating I was not in Park, even though I was. I would have to turn the car back on, shift into drive or reverse, move forward or backward a little bit, hit the brake a few times, put it back to Park, hit the button, and hope it would turn off. It usually took four or five times of this routine before it would finally turn off correctly. It began happening more and more frequently over the course of a week by the time I could get it into the dealer. This is a safety issue, as the car was not fully in Park, and leaving it that way would have drained the battery as well as not allowed me to lock the doors while parked in my driveway. Thankfully, I have an extended warranty (car has 55,000 miles) and only had to pay my $200 deductible, but it was an over $500 fix. As this EXACT SAME issue is prevalent in these cars and was recalled on my same model in previous years, I feel the recall should be extended and these expenditures reimbursed.
