About a month ago when I shifted my vehicle into park and shut the vehicle off, "Shift to Park" appeared on dash display for which I had to restart the vehicle, shift it into another gear and attempt to shutoff the vehicle again. Occasionally this would work but not all the time. Other times when shifting into other gears did not work I had to restart the vehicle, press the shifter button multiple times and then was able to shut the car off with no "Shift to Park" appearing. On 7/11/25, Arrived to work and had to performed the shifting the vehicle into another gear and was able to shut the vehicle off. When I went to leave for lunch, the car would not start at all, check the GM App and it stated "Critically Low Battery". A co-worker helped jump the battery and I was able to start the vehicle. When I went to leave work for the day, the vehicle would not start again with no notification as to why. My co-worker jumped the battery again and vehicle started now with all the system lights on dash staying on and warnings displayed. 7/12/25 Vehicle struggled to start and all system lights were still on. Later in the day, the vehicle would not start and all overhead, dash, display, taillights would not shut off. We jumped the battery and took the vehicle to our local dealer.

My 2019 GMC Acadia started having the known "Shift to Park" issue that is affecting these make/models. This is a known issue and GMC has not issued a recall for it, nor are they covering any cost of repair. When the car is put into Park, the screen displays a message that says "Shift to Park". This results in being unable to turn the car off. The vehicle will not lock either when the message is displayed. On several occasions, the car would not start because of this issue. We took it to the dealer and they are fixing the issue for just over $500 USD.

9 days after taking possession of my 2019 acadia, with less than 900 miles on it, it stopped working. The first time I had a problem I had gotten out of the truck to run into a store. When I tried to start it I was getting a message to shift to park. The electric was on, but the truck would not start. I called for a tow truck. The tow driver got the truck started and advised me to drive it to the dealer less than 1 mile away. While driving on a major road I lost my power steering and stabiltrak, making it feel like I lost my brakes. My experience at the dealer was horrible. They changed my battery and said they fixed the problem. I did not even make it 24 hours before having the same problem. The electric was on but the truck was not running. I was getting a message to shift to park. The truck was off and parked but the dashboard was showing d then p again. I called for another tow, and this time it was actually towed. This time I was told it had to do with the computer. Service fixed it and held onto the truck for a few days to make sure it continued working without problems. 6 days later they called me to pick it up and it didn't even make 5 hours this time. The truck was still running this time, but the electric was going crazy. Every light was lit on the dashboard. As I was driving it to the dealer, the speedometer was going crazy. I was driving steady at around 35 MPH and the speedometer was showing 1, 0, 5, 0, 30, 31, 6, 0, 5, 31, 32, 1, 0, 5, 0. (I have a video of this but cannot attach it).so that was 55 days ago and I still do not have my truck back because gm is supposedly buying it back. I have concerns seeing 4 other people on this forum alone with the same problem.
