When shutting vehicle off after placing in park the display panel shows a message telling driver to shift to park. The vehicle engine will shut off but the electrical system won't shut down until the battery protection timer shuts everything off. Doors don't want to lock but will eventually as well. This occurred previously when the vehicle was about 18 months old and the dealer made a repair consistent with the manufacturers tsb that was issued. The vehicle is now out of warranty and the dealer is trying to get GM to participate in the repair but it's been 3 weeks with no answers.

My vehicle would not shut off after I put the vehicle in park. Kept getting messages that said "shift to park" when it was already in park. The dealer replaced the shift mechanism and the wiring harness at my expense.

- Mars, PA, USA

The 2017 GMC Acadia I own will not recognize when the vehicle is in park. It states to move to park to shut the vehicle off when the vehicle is already in park. This happens when trying to shut off the vehicle but I am unable to because of the "shift to park" warning. I have to push the stick forward and turn the car on and off several times for the message to disappear. Had this fixed by GMC but they refused to cover under powertrain warranty.

Shift to park message on the info panel and car did not go into park and began rolling away. Had to turn car back on to shift into park. On occasion, it requires multiple start/stops. This is safety issue in that if you think you're in park the vehicle can roll and potentially hurt someone because it's not actually in park. The car was stationary when the problem occurred.

The "shift to park" warning message shows up and won't permit car to be shutoff. Vehicle is stopped and at rest and is placed in "park" as designated by shift lever light and dashboard indicators, and the auto door unlock feature activated correctly when placed in park. On 9/21/20, it took me about 10 minutes of trying different positions and by physically moving vehicle to a different parking space. Problem occurs sporadically. This same problem has occurred a total of about 5 times in the last 2 weeks but not as severe as this last time. Vehicle was previously serviced 11/2019, when vehicle was under warranty with 10,062 miles for the same issue in which the dealer replaced a shifter harness. Now, 9/21/20, 10 months later, and 12,400 miles, the same problem has re-emerged. The vehicle is now out of warranty. This is obviously a manufacturing or engineering defect.

Whenever I shift the vehicle to park and turn off the engine, a message is displayed that says 'action required shift to park.' It does not recognize that the vehicle is in park and therefore will not let me leave the vehicle. Sometimes I have to turn the vehicle on and off several times and shift back-and-forth from dr. To park several times before I can get out of the car. I have taken it to the dealer twice now. The first time the fix didn't work and the second time was just yesterday so time will tell.

Vehicle will not turn off. Instructed to shift to park but vehicle is in park.

- Glastonbury, CT, USA

This is the 2nd time, fixes in March 2019. Now having same problem. When I put the SUV in park I get and error message 'shift to park'. according to GMC there is a technical service bulletin issued but no recall. Of course dealer will not cover cost since it was repaired over a year ago. Vehicle was out of warranty already so I already paid over $330 to have repaired once. GMC will offer no help. Sometimes takes me as many as 10 times turning vehicle on and off before I can get the vehicle to clear the message.

When you put the car in park, the car acts as if it is not in park, and tells you to put the car in park. At this point, it will not shut off

- Duncanville, AL, USA

My 2017 GMC Acadia with 40,000 miles on it has been saying 'shift to park' when I try to turn it off. The only way to get it to turn off and be safely in park is to continuously turn it back on shift to reverse or drive move the car a few feet and try again. It continues to take multiple times and the only thing to 'fix it' GMC claims is to replace a lever and that takes 5-6 hours at 135$ an hour and 2 150$ parts. It is not covered under warranty and is a huge safety issue as you either cannot get the vehicle into park and have it safely stuck or it will continue to stay on and possible roll away. There are hundreds of thousands of forums and posts about this issue and even the people who got it 'fixed' still have issues. It is a safety issue and GMC needs to figure out what is causing it how to fix it and do an emergency recall if they cannot figure it out then they need to fully recall the 17-18 Acadias and provide replacement vehicles as this is a major safety risk. I cannot be stuck at a place during a global pandemic because my car is stuck due to an issue that GMC cannot fix.

- Berthold, ND, USA

With vehicle stationary, I attempted to place the transmission in "park" and turn off the vehicle. The dashboard information screen displayed the message "shift to park" and would not allow the vehicle to fully shut down (headlights remained on) even though the shift knob was in "park" as well as "P" displayed on the dashboard screen. The electronic emergency brake was inoperable and the vehicle seemed to be at risk of rolling away. This left me stranded with the vehicle and unable to remove myself from it.

- Stevensville, MI, USA

Shift to park message appears when vehicle has been shifted into park. Car doesn't turn off.
