When I place the gear in park and shut car off, the display states to shift car to park. A loud continuous beep ensues and I would have to start and turn car off several times. The car does not lock nor stop on its own.

The contact owns a 2018 GMC Acadia. The contact stated that while turning off the vehicle, the place shift lever into park message was displayed. The contact had to restart the vehicle several times and move the shifter into the park position for it to disengage. The vehicle was taken to the local dealer who informed the contact about the button on the gear shifter that may be used to reset the system. The vehicle was not diagnosed or repaired. The contact stated that the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 8,400.

I purchased vehicle in 2018 and by 2019 it started showing a message that said error Shift need to park but I was parked and gear in parking mode.I reported to dealer but said they couldn't help me since my warranty was over due to my job I drive alot so I was over the mileage. So they itbwouldnt be covered since then it goes off and on same message and now I can't get off car until it goes off because I'm afraid to let go of brake if the parking gear don't work. I reported to dealer in time to get assistance but they just brushed it off blamed me for the mileage Maybe causing it but I see here I'm not the only one complaining about message "Shift".

When I park my 2018 GMC Acadia, my infotainment screen states the following warning: "SWIFT TO PARK", but I have already put my car in PARK. This warning started appearing around 28,000 miles; my currect mileage on my Acadia is 28,379 miles. I have checked if there are any recalls on this issue, but found none, but this issue started appearing in the 2017 models

Car won-??t go into park though I-??ve shifted to park. Car starts beeping and displays -??SHIFT TO PARK!-?? even though the vehicle is shut off and gear shifter is in park position. I took to dealership, they stated, -??gmc NEEDS to recall this, we have to repair every single GMC Acadia we sell with unfortunately the same defective parts-?? it-??s a $500 fix. I just use my parking break everytime I park now.

The GMC Acadia displays a "shift to park" error. The truck is in park (or appears to be) and the truck says it is not and will not allow it to be turned off. This is a common error with the truck and GMC is refusing to take responsibility and this can cause a fatal error if the truck is not in park and rolls away.

The shift leaver when putting in park has an error code that the vehicle is not in park when it shows it is. The dealer said this is a common problem and replaced the shift leavers wire harness for $600. When this happens there is no way to turn the veh power off and it rolls a little before it engages.

I own a 2018 GMC Acadia and sometimes after shifting the vehicle into park and turning it off I get a message that says "shift into park" even though it is in park. This happens intermittently and but it is a bit of a pain when it does. I have to either jiggle the shifter or start the car up again and shift into park again. I just called the GMC dealer where I purchase the vehicle new, Mark Porter in Pomeroy, OH, and they said there is a bulletin from GMC on it and the fix is to replace the shifter harness which would cost me around $300. And they said if that doesn't fix the problem the next step would be to replace the shifter which would cost me another $500. In looking online it seems to be happening to a lot of 2018 GMC Acadia's and am wondering why there is no recall on it.

Shift to park error when turning off vehicle, which would not allow the engine to shut off. Had to have shifter and harness replaced.
