Gmc acadia keeps flashing the lamp that says to !shift to park, when the car is in park and will not turn off. Does not go off when I turn the car off and does not go off when I reshift the car to park. It takes several trys of putting it back in park then goes off, now it does this every time I park and turn the car off. I'm not the only one with this issue. Its been going on for over week now 38k-ish miles.

The Shift to Park warning message when shifter is already in park shows up on the dash information center. The gear assembly is not working properly, and the artificial intelligence does not recognize park when you are in park. You cannot turn the car off without repetitive turning car off and on and shifting back and forth between drive and park. I was going to live with this aggravation due to costly repair ($656.67), but I went online and found that the car may roll forward if it is not fixed in a timely manner and you don't know if it is in park causing danger if it rolls. Others say put the emergency brake on always. This is a safety issue. Jim Ellis said to bring it to your attention and also write a letter to GMC Corp. I also noted that there is a lawsuit against GMC as they have profited selling the Acadia with this defective gear assembly since 2012. This is the second generation 2017-2019 with the same safety issue problem. Also, you have to replace the battery due to the excessive usage it drains the battery ($219.12)

When parking the suv and placing the gear shift in park, the notification system states -??shift to park-??. This has been happening daily for the last 3 weeks. Sometimes I can get the notification to go away when I push the button on the gear shift. Other times, I have to cut the car off and then back on for it to clear the notification.

After vehicle is shifted into Park, "Shift into Park" message comes up. It requires you to restart vehicle, put in R, back into Park, sometimes jiggle the button, sometimes the entire shifter, sometimes drive around the block and start the process again. The message does not go away even if you exit the vehicle. 2017 Acadia had a recall for same issue, 2 years later still occurring but no recall. The repair is $600! GM offering nothing. Needs to be a recall, if you have an appointment it is sometimes 10-15 minutes of messing with the shifter ro driving around until you can shut your car off. I have been carrying tools and just disconnecting the battery if it won't shut off. Can't be 10-15 minutes late for work every day waiting for my car to agree it is actually in Park!
