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 600.00. When this happens there is no way to turn the veh power off and it rolls a little before it engages.
