Shift vehicle into park. Turn vehicle off. Warning light comes on and says "shift to park." Turn vehicle back on. Move shiftier from park to 3rd gear. Turn vehicle off. Warning light comes on and says "shift to park." Do this a few more times and it finally stops giving me the warning. It does this intermittently.

The second row seats get stuck from time to time when attempting to fold them down. We have also been having issues with the shift gear when trying to place it in park. When the car is placed in park and we try to turn it off, the car will refuse to shut off and will ding until finally the car registers that the shift gear is in park. I have to turn on and off the car multiple times, and even wiggle the gear multiple times before the system finally recognizes that the car is in park.

Shift to park known issue has started. I've had the car for 1 yr. 5 months. I know there are lawsuits on this issue. Continuous issue and getting worse. This needs to be taken care of by GM. It is epidemic in their Acadias. Stationary and putting it into park. It doesn't recognize it's in park! it's been occurring off and on over a week, not today, every time I try to turn off the vehicle.

I have received the 'shift to park' error message on the dash when the car is already in park. One time with the car off, the error message on, the car started to roll despite it being in park. I had to restart the car, shift the shifter down then back to park back down and back to park before the car would recognize the shifter was in park. Each time this happened when I was in a parking spot and in my garage.

Put car in park and push button to shut car off and motor turns off but it's in accessory mode and the display message says to shift to park. Takes numerous times turning car on and off and moving the shift button around before it recognizes that the car is in park. It started a month age where it would happen only once and when I turned the car on and back off it stayed off which made me think it was human error. This last time it took me an hour before it recognized it was in park search the internet and see other people having the same problem and GMC is aware but no recalls.

The vehicle was stationary and did not allow me to turn the power off. Shift to park message would not go away even though the vehicle was clearly in park. I had to try 10-15 times to put the vehicle in other gears and park again and turning on and off until it eventually turned off. This has happened several times and if I just leave it with the message there the car eventually drains my battery. It has been happening for a week during several different occasions and am concerned it could drive away on its own if it happens again and I can't get the message to turn off.

First of all, this issue is being reported by hundreds if not thousands of GMC Acadia owners. I received the "shift to park" message months ago while it still was under the 36,000 mile warranty and then it went away until last week. I got a "shift to park" message when I turned the vehicle off even though the gear was in the shift position. This caused a number of secondary issues that are now compromising the safety of the vehicle. Once I am able to turn the vehicle back on after it drains or kills the electrical system, I am getting a number of issues. However, the ones that concern me the most are the rolls even though the vehicle is in park, loss of power steering, loss of AWD, loss of stabilitrack, loss of ABS, braking system error and power surges. These are the most concerning but I am also having issues with my dashboard, navigation, and vehicle instruments. I called the GMC dealer who had no problem telling me the gear shift box needed to be replaced, not covered under warranty and they had no idea when they can fix it because it was on a national back order. What really disturbs me is that there are lawsuits going on dealing with this particular issue and that literally it compromises the safety of the vehicle and neither GMC or the NHTSA have acted on this. I was driving today and realized how dangerous it was to operate a vehicle under these conditions. You can literally be driving and the vehicle have a power surge which makes you lose control caused by a malfunction in the gear shift box. I am assuming that no one will due anything until several people are either killed or seriously injured. This issues has been reported on models going back to 2017 and here we are in 2019 and still have the issue. Please help us, this issue is happening to thousands of drivers and it is not being addressed by the NHTSA or GMC. Please recall or stop selling

GMC Acadia "shift to park". the SUVS fail to detect when the gear shift lever is moved to park. The dash board showa a message on the instrument clusters that says shift to park even though the gear shift levers are already in park. In addition to losing the ability to shut off and lock the SUVS, I was unable to turn the SUV off after attempting to do so serveral times.

GMC Acadia will not register when the driver shifts the gears into park. An error message 'shift to park' is shown on the dashboard even though the gear is in park. The driver is unable to turn the car off because of the error message. It takes several turns of switching the car on and off and flipping through all the gears in order for the message to disappear so that the car turns off. The car was taken to the dealer on June 26 for repairs and has been sitting there over a month because they are unable to correct the issue.

On separate occasions, both parked turned off and running down highway, the dash lights lit up and alarms chimed. Car wouldn't start, no cold A/C. the "service power steering" message displayed. Car didn't turn as well. Couldn't shift. After doing so for a about 2-3 minutes it would go back to normal. The attached photo was while driving down the road you'll notice it doesn't measure any RPM's however the car is moving about 40mph

The service stabiltrak notifcation keeps coming on and shutting off on its own while in motion on a street and it has also happened while on the highway. It has occurred at different speeds and several times with different people driving.the dealership can't figure out why and it doesn't show it even came on at all. When in motion on a strret going 46mph the car tried to auto correct pulling me out of my lane by itslef. It was a straight street with no curves where this occurred. Thank god there wasnt a car in the lane next to me. The side mirrors reset themselves all the time. If I move the seat and then hit the memory button so it will go to the set position the seat doesn't move at all. I have had rental cars more than my Acadia the past 2months while the dealership trys to get these issues fixed. I love the car but am getting mad with all these issues.
