Vehicle does not recognize when it is in park. At times vehicle will not go into park and makes me concerned for my family's safety. My understanding is that GM is aware of this issue.

Acadia

Every time I park and try to shut car off the car refuses to turn off and gives a message that says shift to park. Requires 20+ attempts of restarting, shifting out of park and back into it before succeeding. Car is clearly in park, not rolling but I'm unable to turn off car fully. This has been occurring the last month or two. I bought the car brand new.

When you shift to park the vehicle does not go into park. Took it to the dealership and they replaced the jumper harness (84733196) on May 1, 2020. That did not fix the issue on July 24, 2020 dealership replaced the shifter (84699764) trans control. This occurs when we are stationary attempting to place the vehicle into park from driver or reverse.

Shift to park known issue has started. I've had the car for 1 yr. 5 months. I know there are lawsuits on this issue. Continuous issue and getting worse. This needs to be taken care of by GM. It is epidemic in their Acadias. Stationary and putting it into park. It doesn't recognize it's in park! it's been occurring off and on over a week, not today, every time I try to turn off the vehicle.

When you try to put the car in park it states that its not in park. It will not shut off. You have to start the car and shut off multiple times and hope that works. I've looked it up and there is a lawsuit about it but no recall. It does this every time I drive somewhere and try to turn my car off.

I have received the 'shift to park' error message on the dash when the car is already in park. One time with the car off, the error message on, the car started to roll despite it being in park. I had to restart the car, shift the shifter down then back to park back down and back to park before the car would recognize the shifter was in park. Each time this happened when I was in a parking spot and in my garage.

When I put my car into park a shift to park message appears. I have to move the gear shift several times to finally get the car to shut off. Sometimes it takes 10 minutes! it happens every time I turn the car off. I have to sit there with my foot on the brake because I'm afraid it will roll away.

GMC Acadia is placed in "park, " clearly shown on the dash board with the "P" highlighted red. When the power button is pressed, a "shift to park" alert pops up and will not allow me to leave the car. This caused me to be late to work this morning. Then tonight, after working a 12 hour shift at the hospital on thanksgiving, I had to sit in my garage for 20 minutes trying to turn my vehicle off.
