About a month ago when I shifted my vehicle into park and shut the vehicle off, "Shift to Park" appeared on dash display for which I had to restart the vehicle, shift it into another gear and attempt to shutoff the vehicle again. Occasionally this would work but not all the time. Other times when shifting into other gears did not work I had to restart the vehicle, press the shifter button multiple times and then was able to shut the car off with no "Shift to Park" appearing. On 7/11/25, Arrived to work and had to performed the shifting the vehicle into another gear and was able to shut the vehicle off. When I went to leave for lunch, the car would not start at all, check the GM App and it stated "Critically Low Battery". A co-worker helped jump the battery and I was able to start the vehicle. When I went to leave work for the day, the vehicle would not start again with no notification as to why. My co-worker jumped the battery again and vehicle started now with all the system lights on dash staying on and warnings displayed. 7/12/25 Vehicle struggled to start and all system lights were still on. Later in the day, the vehicle would not start and all overhead, dash, display, taillights would not shut off. We jumped the battery and took the vehicle to our local dealer.

We receive a shift to park message when we try to turn our 2019 GMC Acadia off. The vehicle is already in park, but an alarm bell keeps going off telling us it is not. The vehicle will not allow us to shut off the vehicle properly and results in battery drain and inability to lock the vehicle. We have noticed there is a class action lawsuit and recalls from previous year's models and the 2019 model manufactured in Ohio, but ours was manufactured in Tennessee. Our year, make, and model isn't listed in the class action lawsuit and/or a recall. This is very frustrating considering the number of similar issues/complaints in regards to this shift to park problem. I feel GMC as the manufacturer should be held liable for a faulty part and they have failed to correct this issue in later models since they were aware of the issue with the 2017-2018 Acadia models built in Tennessee.

In March 2025 my 2019 Arcadia with only 44112 miles begin indicating a Shift to Park error message when I parked and shifted into park the error message showed on the instrument panel and the warning alarm sounded and would not stop showing the error message until I restarted the car and shifted from drive to park repeatedly. I couldn-??t get out and close the door, and the warning stop, it would continue to sound the warning. The only way to stop the warning message and alarm was to stay in the car and repeatedly start the car shift to drive into park switch it off and if it still showed the error and warning, do it all over again. This could take up to several minutes and many tries. If I had of left the car all the warning would have been sounding indicating it wasn't in park. I didn't know if it was really in park or not and if not, the car could have potentially rolled off causing injury or damage. To try and determine what was the cause of this problem I searched the internet to find a solution, to do a reset or simple fix and discovered that GMC had known about this issue since 2016 and the only solution was an in the shop repair requiring replacement of some parts. The "Shift to Park" error in GMC vehicles is considered a safety issue by many owners and has led to class-action lawsuits. The issue, which prevents vehicles from recognizing when they are in park, can lead to the engine not shutting off, potential for vehicle roll away, and even entrapment inside the vehicle. On April 16, 2025 I had the repair done at Hayward Allen, Cadillac -?" GMC dealership, 2590 Atlanta Highway, Athens Georgia 30604. The total repair cost was $732.36 (invoice attached). ). I sent a copy of this invoice by email to GMC customer service. After customer service reviewed the amount they call and informed me they could only reimburse me a total of $73.24.

Shift to park light comes on and car won't shut off

- Philadelphia, PA, USA

Shift to park issue. This 2019 Acadia Denali has been serviced twice for a shift to park issue:(It-??s a known problem that occurs when Acadia vehicles fail to recognize that the gear shifter is in the park position). The first time was under warranty in 2022 and it has just been serviced again for the same problem. The system is the same as the older GM recall for this problem and the recall should also include this model as well but unfortunately it does not.

- Penn Valley, CA, USA

Component: Shifter Assembly & jumper harness Safety concern: Can't turn off vehicle - Carbon Monoxide poisoning, physical safety when parking not at home, as I would have to leave vehicle running... Message in dash was present when I brought vehicle to dealer. Dealer also replicated No inspection other than dealer. Part returned to me. Warning message has been coming on for past 60 days or so, progressively getting more frequent I receive a 'shift to park' message in telltale after I have shifted to park. At times, vehicle will not shut off until shifter is manipulated for several minutes. I have concerns that I cannot park vehicle in garage, if I cannot shut it off. GM is well aware of issue, but has yet to recall them. Dealer actually had replacement shifter in stock for a same day repair.. I was charged $778.98 for the repair, and GM's customer assistance center response to me simply was to file a complaint with NHTSA. My wife does not feel safe driving, as there is no guarantee vehicle will turn off. Dealer replicated issue when I brought to dealership. Dealer has replaced part and has them. Warning lights only appeared when problem reared itself, initially began about 60 days ago, but is not occurring on approximately 2 of 3 shut downs.

My 2019 GMC Acadia with 33,000 miles on it started to give me a notification to "Shift to Park" even though I had already shifted the vehicle into park. A "ding! ding! ding!" alarm wouldn't go off and the vehicle wouldn't turn off unless I repeatedly changed the gears until it read it was in park. This went on for a few weeks and got progressively worse. I read on a GMC forum that the vehicle could slip out of gear while driving and potentially cause an accident. My mechanic found the shifter assembly to be defective and replaced the entire Gearshift Lever Assembly. He said there was a plastic piece in the gearshift that snapped off and said this was an issue in the older models but thought GMC had fixed this issue by 2019. Unfortunately, I was past my 3 year / 36K mile warranty and had to fork over $1300 to have it repaired.

Our Arcadia 2019 with 40000 miles has shift to park problem. 2017 thru some 2019 had recall notice and were fixed by GMC. Why doesn't it apply to this vehicle. We had to pay $1500 to dealer. There is an obvious problem and they have admitted it. Time for government to step in or do a class action lawsuit looks like they are filed by state

When shifting into Park the car still states to "shift into park" on the dash and will not fully shut off. i still need to take the car into the dealer for service to fix. This seems to be an issue.
