My wife was taking the children to school when she arrived she placed the car into park and attempted to shut off the vehicle. Once the power button was depressed a beep was heard and the dash said shift to park. She had to turn the are on and off multiple times. I contacted gm and they said there is a defective pin in the shift controls but this issue is not covered by a recall.

The contact owns a 2018 GMC Acadia. The contact stated that the vehicle failed to start and restart daily and required to be jumpstarted. Additionally, while the transmission was shifted into park(P), the "Shift to Park" message was displayed, and the vehicle failed to turn off, causing the battery to become drained. Roadside Assistance was able to jumpstart the vehicle. The vehicle was taken to AutoZone and Firestone, where the battery and alternator were tested; however, the cause of the failure could not be determined. The contact purchased a battery jump starter to jumpstart the vehicle. The vehicle was then taken to Pep Boys, where the alternator, battery, and starter were all tested, and it was determined that the engine switch had failed. Pep Boys advised the contact to take the vehicle to the dealer for a diagnosis. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was 81,737.

Vehicle when being placed into park utilizing the gear shifter begins to say “vehicle not in park” when the vehicle is in park. This happens almost every time the vehicle is placed into park. In order to clear that notification, you have to put the vehicle in drive and park multiple times and hope that the computer recognizes the vehicle in park to unlock the doors and shut the vehicle off.

On July 26, 2024, I was driving my 2018 Acadia, with my cruise control set to 48 in a 45 MHP zone. Nearing a bad curve, I sneezed. When this happened, I tapped the brakes to disengage the cruise control, my passengers side tires exited the road and with both hands on the wheel I tried to slowly bring my tires back to the road. However, I was unable to gain control and totaled the vehicle. A witness stated that she heard a loud pop coming from the vehicle before the wreck happened. I later learned from my insurance that the vehicle had a Recall 17V516000 on it and I was never made aware of it. I believe that this was a factor in me not being able to control the vehicle.

I purchased my 2018 GMC Acadia in 2021. Two days after I purchased the "Shift to Park" error occurred. I contacted the dealer and they said that yes these cars are not recognizing they are indeed in park. After several phone calls back and forth they agreed to repair. Well now 3 years later it began to show the Shift to Park error once again. I looked up to see if they had recalled yet and GM has recalled on SOME vehicles but not sure why others like mine are excluded. I would assume this is a safety issue since the car cannot recognize its in park. I am also not returning to the dealership for repair since I don't believe it was repaired to begin with or the replacement parts are also defective. This seems to be that it will be an ongoing issue and additional costs to me every time this issue comes up.

I have increasing issues over the last several months, most especially this last week or so, with the SHIFT TO PARK. Every time I place it in park the dashboard says SHIFT TO PARK and bings at me continuously. I try turning the vehicle off and on again numerous times and have to place in reverse and park again a few times before it "clicks" into park and allows me to leave the vehicle. I know my year and model are part of a recall for this issue, there are class action lawsuits about it as well as Lemon Law incidents in numerous states. I have called GMC and received no help, I asked to escalate it to a manager, I was told that would happen within 24-48 hrs yet no manager ever called me. I was left to place a complaint with the Better Business Bureau and a GMC "scripted" representative called me and told me that MY vehicle has not been recalled, yet my model and year has been -- this makes zero sense since MY vehicle is having the recalled issue. I asked again to escalate it, a supervisor is supposed to call me within 2hrs (July 9th at 4:10pm EST) but emphasized that the supervisor will also tell me that GMC will NOT pay for my recall because my VIN has not been recalled. This is how they get away with not paying for the vehicles issues. HOW is my vehicle now NOT part of their recall when it's a known issue and my vehicle IS having this issue?? I drive 2 toddlers around, my grandchildren, and now I have this issue on a vehicle that is barely a few years old and I've only owned for 3 years. Again, my YEAR & MODEL vehicle has known issues with this SHIFT TO PARK and GMC is refusing to remedy it.

The transmission was failing to shift and jerking me forward in the vehicle. The check engine light came on. I was on the highway going at high speeds. Also, my vehicles Internet connection dropped. I pulled off the highway and turned off my vehicle. While starting my vehicle again and attempting to go into reverse, it would not reverse and it would not drive forward . It would just rev the RPMs. My vehicle has been sitting at the dealer for two weeks. They have not looked at it yet. The police were not called as there was not an accident, thankfully. The warning light came on as the vehicle was failing.
