The gear system fails to recognize when the car is in park. I have had the gear box replaced once on this car, and it is failing again. The car has 92000 miles. The problem is that I cannot shut the car off completely or lock it because the system does not recognize that the car is in park. My dealer told me last time that the problem is caused by a faulty sensor. Now it's happening again. This is a major issue and GMC needs to correct it. Thankfully I bought an extended warranty so they will have to fix it again, but this is absurd. No other car I've had has ever had this issue.

Had to replace the shifter, harness, and parking assist module to the tune of $1569! When it was put into park the system would not acknowledge it was in park...therefore I could not lock the vehicle and an alarm kept going off. My Acadia only has 12,000 miles on it...NO excuse for having to replace those parts with or without a warranty! Dealership said I am not the only one this has happened to...they have replaced a number of them!

Shift to park notification keeps coming on after shutting off the car. It obviously has been shifted in to park before turning off the engine, but the notification keeps popping up. I have had the shift harness replaced by a mechanic once alreafy. He says this is the GMC authorized fix. IT DID NOT FIX THe PROBLEM! Of course, he'll put another shift harness for me, but what are the odds that will solve anything. GMC needs to come up with a better solution! It is frustrating and time consuming trying to come up with whichever trick will work to make the notification to away. I am not a very happy customer!

when the car is in park it thinks its still in gear and there is an alarm that says "SHIFT TO PARK". Car cant be turned off. It rolls. its unsafe. It was repaired once for this in 2019. It came back 2 weeks ago. Dealer wont honor correcting the repair.

When the vehicle is in park, and I attempt to turn vehicle off, I get a messege saying to put vehicle in park. Vehicle will not turn off.
- Pen Argyl, PA, USA
I'm getting the "Shift to Park" message when my vehicle is already in the Park position. This issue first started happening in 2019 and I took it to my local GMC service center to be looked at since it was still under warranty. It started happening again about 2 weeks ago. My extended warranty and powertrain has expired, so I'm concerned that the same dealership will charge me for this repair when I take it this week. If this is a known issue with this vehicle, as evidenced by the scores of complaints related to this issue, why isn't there a recall on this vehicle?
- Jackson, MS, USA
Shift to park warning is coming on, I am not able to turn the car off. The car is rolling either forward or backward while in the parked position. I have to turn the car on and off many times plus put it in forward, reverse, neutral and most of the time that still does not fix the problem. The car will not turn off, and it is rolling forward or backward while it is parked.

When I put my car in park and turn off it will randomly say "shift to park" it started doing this in Aug or Sept 2019 the car was under warranty and I brought it to a dealer to "fix". fast forward April 2021 it started to say shift to park again and car is no longer under warranty. Called different dealers even the one I brought the car to fix problem (that was a joke), they know its a problem and saying since that part got fixed in 2019 with a bad part and now there is a a newer fix that should work better, but I will have to pay for diagnostic test and part again. Again they know it is a problem with these cars and it needs to be recalled. I have to turn the car off and on reshift, push the shifter harder, etc to get the message to go away so I can turn my car off.

My 2018 GMC Acadia was bought used. It has an issue with the shifter regarding "shift to park". when the vehicle is placed in park the sensors or computer does not recognize it and you have to shift in and out of park to get it recognized. I called my local GMC dealer in Tennessee and they said it was not under recall and my vehicle is not under warranty. They wanted $400 to fix the problem or issue. Upon an internet search I learned that this is a common problem with this model. I feel as a consumer that GMC should generate a recall on this issue regarding "shift to park". thank you

Keep getting parking shift gear warning even when vehicle is parked. Happens frequently
- Hammond, IN, USA
I was getting a shift to park error message when putting my Acadia in park. I had it repaired on 08/18/2018. The same problem came up again and was repaired today 10/19/2020. This is a safety issue and very frustrating. My warranty expires on 12/14/2020 and because there are so many complaints on the GM authority website this should be a recall so myself and others are not stuck with paying for something that is no longer under warranty. This happens when a vehicle is put into park and then this shift to park error message comes up. Sometimes you cannot even shut the vehicle off. Both repairs involved replacing the shifter assembly. This is a GM problem and should they should issue a recall.

When the vehicle needs to be shifted to "park", the car notifies you on screen "shift to park" and then becomes stuck and you have to keep wiggling, trying to get it to actually park until the notice goes away. It happens at random and has been going on for the last two weeks. There seems to be no recall, yet the 2017 2018 models are all having this same issue and there is no recall yet. This is a huge safety issue and we are now being responsible for the charges to have it being fixed. This should not be my responsibility as it is hugely aware to all the dealerships and there are court cases being filed because of this.

- Papillion, NE, USA
When I shift to park, when I'm out of my car it starts rolling and saying that I need to shift to park, even though I'm already in park.
- Greenwell Springs, LA, USA
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.
- Georgetown, KY, USA
Vehicle is not recognizing that it is in park therefore resulting in the vehicle not shutting off

2018 GMC Acadia shown 'shift to park' message even car is stopped/ parked.
- San Francisco, CA, USA
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.
