Yes, my vehicle is available for inspection upon request. When I go to put my 2019 GMC Acadia in "park" the shifter states it is in park & the dashboard shows it in "P." However, when I turn the vehicle off, an error message comes up reading "shift to park" and my car wont fully shut off. You can feel the car move forward or backwards a tiny bit (depending where vehicle is parked). This makes me have to turn the vehicle back on, shift into "drive, " back into "park, " and then shut the engine off and pray the "shift to park" display doesn't come up. This process was repeated this morning when I arrived at Walmart 3x before it finally shut off, then when I got home it happened at least 8x before I could safely leave my car in my garage without the worry of it not truly being in park. This has gotten to the point I have bought wheel chalks to put around my car tires because I am afraid this vehicle could roll down my driveway into my neighbor's house or kill some kid playing in our culdesac. I let the last place I was at know & they told me GMC was aware of the issue, but that there was no way to fix it (Auto Revival in Justin, TX). I am unsure as to whether this issue happened for them or not, as nothing was mentioned after being told GMC is aware. That was on January 10th, 2024. No one else has looked at it besides that. It seemed to be occurring less frequently for several months, and then now it is the worst it has ever been.

I would park my car and try to turn off car. The car would not turn off. The car continued to ding the car remained on. The safety issue is the car wouldn't turn off. After many many times shifting from park to drive it would finally park, this happened every time using the car. I discovered the same exact issue is a recall on 2017 & 2018 GMC Acadia our exact car ! Called the dealer explaining SHIFT TO PARK issue. Brought the car to Buick GMC of Mahwah they noted in fact it was SHIFT TO PARK issue. Two days later came in for the car they would not cover problem. Cost $950 for exact recall the 2 years prior. Also, contacted GMC corp. they were no help just said had no recall. Our car is 2019 Acadia with 27,236 miles.

I randomly get a "shift to park" warning even though the vehicle is in park. It looks like there has been this same issue with older years but not my vehicle according to the VIN.

- Lynn Haven, FL, USA

The "Shift to Park" error warning comes on even though the vehicle is in park. The vehicle will not turn off. I had this issue with my 2017 GMC Acadia. They tried to fix it once, but it came back. I see in the 2019 version that they have added an audible dinging to the warning. I would have thought after at least 2 years they would have resolved this issue. They just made it more annoying by adding the dinging.

Vehicle does not know it's in park. Can't turn off vehicle. Must shake or beat the shifter knob for vehicle to see it's in park.

My radio is going crazy. Like going through every radio station, calls people. Its a distraction. And after researching how to fix I noticed thousands of people have the same problem. Almost cause an accident because of the distraction and this is obvious problem in GMC.

Last week I parked in a large public parking lot and attempted to turn my car off. I received a notification in my dash to -??shift to park-?? even though my car was already in park. I was unable to turn the car off or lock the doors. I ended up having to leave. I have now gotten this message six times in the past week. It can take up to twenty minutes to get the car to turn off so I can exit. Yesterday upon returning to the car I showed an error message as soon as I started it that the parking brake needed service, stabilitrak is disabled and steering assist is disabled- drive with care. As I tried to exit the parking lot, I found it almost impossible to turn the steering week. I pulled over and restarted the car, releasing the steering wheel so I could get home. This morning, all of the service lights were on and periodic warnings flashed on my dash throughout my drive to work. I contacted the dealership and was told that there is a recall for this exact issue on the 2015-2018 models of my car. I have a 2019. This is certainly a dangerous issue that should be proactively fixed and is clearly still present in years that are not being included in the recall. I was told my car was one month past its warranty and told I could pay 250$ for the issue to be assessed and then they could quote me on a fix. The dealership acknowledged that this is an issue they regularly fix.

My car will not shut off as I am parked and -??shift to park-?? is alerting me. The car keeps beeping. I have to re-start it multiple times and shift it in and out of park for it to finally go off. This last time it took 25 min to shut my car off.

When attempting to park vehicle, the alert "Shift to Park" populates and the car will not completely shut down. This happens sporadically and can take up to 15 minutes to get vehicle in the right position to completely park and shut off. If it's not in the proper park position, the car can continue running, battery drainage and possible roll out of place. This also causes issues with the transmission not shutting off. I have not had this particular vehicle inspected, but contact with dealer service departments confirms continued complaints of this issue and it has not been addressed by GMC/General Motors. Problem has been occurring at various times over last 3 years.

Shift to park will not work. Sometime after 20 try-??s it may work once but I have to disconnect the battery to turn off the car. I-??m beside myself and cannot keep doing this. This is a real safety problem. I have children in my car and Gm says there is no recall and I am expected to pay $800 and then it is not guaranteed.

When I put my car in park and try to turn it off, the dash shows an error message "SHIFT TO PARK". The car will either not turn off the ignition or allow me to leave the vehicle or lock/unlock the doors. It alarms incessently--even when trying to move the shifter around. Takes several times of restarting and shifting to get it to clear so I can put it into park and exit the vehicle. Local dealer is charging me over $2000 to repair the transmission control shifter assembly; BCM low signal; in-line shifter wire harness jumper--exactly one month after my warranty expired. It's a KNOWN Acadia (and other GM vehicle) issue--per several bulletins--NA-19-206 as an example.

My vehicle just hit 39K miles, it has all of a sudden started giving me a Shift Into Park warning. The sensor is not registering that its in park and will not let you turn car off. There is a recall on the 2017-2018 vehicles for this issue and but many report an issue with the 2019, when I called GMC they would not fix. How to we go about having this included in the recalls?
