GMC Acadia is placed in "park, " clearly shown on the dash board with the "P" highlighted red. When the power button is pressed, a "shift to park" alert pops up and will not allow me to leave the car. This caused me to be late to work this morning. Then tonight, after working a 12 hour shift at the hospital on thanksgiving, I had to sit in my garage for 20 minutes trying to turn my vehicle off.

I put my 2018 Acadia in park in my garage (a flat stationary spot) and I receive a message that states 'put vehicle in park', which it already is in park and as a result the engine won't shut off. I have had this occur several times over the past month, but most recently occurred on October 24, 2019. It is my understanding it is possibly a bad shifter assembly which not only will keep the vehicle from shutting off, it can also not hold the vehicle in park. I have researched this issue and I am disappointed to discover that GMC is aware of this issue occurring with the vehicles. This is a serious issue especially if it will fail to hold your vehicle in park.

Shift to park icon comes up and will not let me turn off vehicle. This is dangerous and needs to be recalled. And to top it off, I sent it to a GMC dealer and they told me they have to order parts but since GMC is on strike the parts will take a little while to get here.

I went to put my vehicle in park and it showed me a shift to park message. Took it to the dealer twice to get it fixed. Today it happened again, but this time it's stuck on drive and left me stranded in the parking lot. I had to put the emergency break on, disconnect my battery and leave my car for it to be towed to the dealer tomorrow or Monday.

Shift to park 2018 GMC Acadia AWD error message saying vehicle isn't in park; multiple attempts to move shift lever, turn off and on, etc fail to turn off the error message so the car will completely turn off. Car turns off but the alarm keeps beeping saying it's not in park. Vehicle has been at the dealer for over 2 weeks with no, zero, date of replacement to arrive. Vehicle is owned (no fiancing, no lease). Paid for a $50K vehicle that I can't drive. Not safe, not useable.

When pushing vehicle ignition button "start/stop" to turn vehicle "off" it will turn the engine off but keep the vehicle still "on" using the battery. If I open the door and shut it, the horn honks to alert that the vehicle is still "on" and not completely stopped. The only way to get the ignition button to acknowledge the vehicle is off is by jerking the gear shift until the green light goes to "off". it does not do it every time I turn the vehicle off, but it does it about every other time. I will take it to the dealership very soon for them to look at this also.

One day my car started telling me shift to park while it was in park. As the day progressed it became worse and worse. Resulting in the car not shutting off. Putting it into gear and back to park was not helping. The last time it took nearly 30 minutes before I could get the car to shut down completely as it kept staring shift to park. Car was not moving had only gone within city limits with max speeds of 45mph.

When I turn the car off I receive the message shift to park. The car is already in park and I have to shift multiple times for the car to register it as parked.

- Morgantown, WV, USA

The vehicle would display a dashboard warning "shift to park." Every time the vehicle was put into "park" the vehicle would not register that it was in park. This would prevent the vehicle from being turned off. A driver would think the vehicle was in park, and take their foot off the brake, but the vehicle would not register it was in park and would display a warning on the dash "shift to park." You would then have to shift back and forth, from park to reverse or drive and then back into park for the vehicle to finally register it was in park. This would occur while the vehicle was stationary and sitting anywhere you would park the car.

When putting my vehicle in park and pressing the engine off button, I get an error message "shift to park", and the vehicle beeps and will not turn off the electrical, but the care is already in park. I am unable to turn off my vehicle completely. I have to press start again and put the car in reverse and back to park, sometimes multiple times in order for the vehicle to register that is in park and allow me to shut off my vehicle completely. I am concerned that the vehicle may not actually be in park when I put it in park. I do not want it to roll down a hill and I want to be able to turn off my car without being concerned it will continue to run electrical and kill my battery.

'shift to park' error message is showing when my vehicle is already in park and I'm trying to turn the vehicle off. I purchased this vehicle less than a month ago and it currently has 33K miles on it. I've had to turn the vehicle back on several times to get this error to go away. When the message flashes I've even experienced the vehicle rolling indicating it is in fact not in park although the shifter is in park position. This needs to be recalled immediately and I will also be consulting an attorney as this is a known issue with no clear fix (many people who have had the shifter replaced are having the same problems again) and the part that needs to be replaced is on backorder. People's vehicles literally cannot turn off resulting in batteries dying among the very obvious safety concerns. How is this legal?

Car will not recognize I've shifted to park when I turn off the vehicle. It says shift to park when I already have, and I have to start the car and shift again over and over to park for it to work. Very concerned about safety.
