"shift to park " message started coming on the display even though the vehicle is in park. Once this message comes on, I am unable to turn the vehicle off. I have to keep putting the vehicle in gear and park again several times until the message goes away. I have video of the issue but dont see where it can be uploaded. There is also a class action lawsuit in conn about this issue.

When I shift the car into park and turn the car off, the car indicates "shift to park" and dings until I move the gear shift around for several minutes, and then the indicator statement and sound stop. This happens approximately half the times I park and turn the car off.

First it said parking wasn't working correctly. Then I checked to make sure the park brake was off, then when I shut the engine off it said it was not in park and the dash lights stayed on..

Vehicle does not recognize it's in park. Vehicle won't shut down completely, it honks horn and beeps inside and won't let you lock doors or restart car. Haven't noticed it rolling away like many people state... jerking the shifter seems to get it working so far.. haven't been stranded yet.vehicle was stationary in a parking lot

My 2019 Acadia keeps beeping when the car is in park and I shift it off with an error message 'shift to park'. I have to turn the car back on, shift the car out of park and back into park. I am now doing this 10 times or more. I called the dealer after researching that this is an issue with the car and have not issued a recall. This is a problem. By starting and turning off my 10 times I am putting a strain on the starter. I am afraid the car will roll when it's off with this error message.

When I try and turn the car off it has an error message that says "shift to park". the car is already in park and message still. Need to do a ignition cycle to remove the condition and be able to turn it off. This condition happened randomly, still occurring one or twice a week.

The manual gear shifter controls in low gear on the center console do not shift. The manual control worked during the test drive at the dealership when the car had 17 miles on it, March 10, 2019. The shifter failure was first noticed when the car had about 500 miles on it, coming down a mountain on a highway when we tried to use the engine to brake instead of using the foot brake on March 30, 2019. In between those two dates on March 21, 2019, the car had a water leak after it rained that dripped into the cabin of the car and directly onto the shifter and other electronic controls. I believe the gear shifter failure is a direct result of water dripping onto the shifter and other electronics on the center console. I have 3 documented service records attempting to repair the water leak after 3 separate rainstorms that was ultimately determined by GM engineering to be a manufacturer defect. When the glass is positioned for the rear moonroof, the positioner is supposed to hold the glass in place for a moment to seal. Instead the positioner moves creating an air pocket. This results in water intrusion into the ceiling of the vehicle after rain, which then seeps into the fabric liner and drips directly onto the controls. I am worried about where else water has travelled within the car, knowing it was manufactured in July 2018 and stored outside most of its life. The shifter is the first of what I foresee as many electrical issues that can ensue with water intrusion, as it has occurred in a car having under 900 miles on it. With all electronic transmission controls, I am worried that if water damaged the low gear shifting, there could be future and more detrimental transmission malfunctions (possibly catastrophic). Beyond electrical failures, mold is a worry in the headliner and carpets creating a health hazard in my vehicle where I Transport my two small children.
