When the car is parked on a flat surface (inside the garage, parking garage, parking lot), the car will display "shift to park" when it is already in park. The accessories stay on until the driver is able to get the car's computer to notice the car is in park.

Placed the vehicle in park, it was stationary and it rolled forward. Message in the info center said "shift to park". I was parking in a mall parking lot.this has occurred 5 times. I can push the gearshift back and forth and then it can be turned off and the message will disappear. I took it to the dealership and was told they are waiting on GM to see what can be done. It makes a sound when in motion at slow speeds on a city street like the back needs shocks. It seems to bounce more than it should.
The contact owns a 2017 GMC Acadia. While the vehicle was engaged in park with the engine running, it inadvertently rolled away. As a result, the occupant was struck by the door and the vehicle ran over the occupant's foot. Medical attention was required. The vehicle continued to roll away and rear ended another vehicle. A police report was not filed. The vehicle was taken to an independent mechanic where it was awaiting diagnostic testing and repairs. The dealer was not contacted. The manufacturer was notified of the failure. The failure mileage was approximately 3,002. The VIN was not available.
When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of "shift to park" appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. I took the vehicle in for service on 6/4/18 and was told that GM is aware of the issue however their engineers have not found a solution. This currently is forcing me restart the engine, put my car in reverse, shift back in drive, try re parking and turning off again repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I'm afraid that it might cause a dangerous situation.

A message shift to park kept appearing when the car was in park and shut off. Then I put the car in reverse and the entire care locked up. (a message from GMC -General Motors llc (GM) is recalling certain 2018 Chevrolet equinox and GMC terrain vehicles and 2017-2018 GMC Acadia vehicles. The right front intermediate driveshaft may fracture and separate while driving.)
2017 GMC Acadia denali AWD. While accelerating on to a highway, after moving forward partially into a lane, my vehicle locked up and would not move forward. When pressing the gas pedal, a loud griding noise would occur. Weeks later, problem undiagnosed and vehicle still at GMC for repair.
The vehicle shifts very harshly between second and third gears when accelerating. Sometimes it is so harsh that it slams you back in the seat. The dealer says that it is "normal". it began after owning the vehicle for one full year.
When the vehicle automatically goes into V4 mode there is a vibration inside the cabin. The vibration also sounds like a boom noise inside the cabin and the vehicle shakes while driving. The problem seems to occur at 1500-1700 rpms and will continue until you accelerate and make the vehicle go back into V6 mode. Dealer attempted to fix the problem on 2 occasions but was unable to. Dealer acknowledged the problem and categorized it as a vibration, drone, flutter or boom noise inside the cabin while vehicle is in afm V4 mode. Problem has not been fixed.
My 2017 GMC acadis 6 cylinder AWD has excessive vibrations that occur at 1400-1600 RPM and at various speeds.it seems like the transmission refuses to shift and it lasts for up to a quarter mile.vibration is most pronounced at speeds of 55-60 mph the dealer diagnosis says it is functioning normal. The struts were replace AT1390 miles and motor mounts adjusted, problem remains, auto brought to dealer for recall as per bulletin 17109 but it still vibrates excessively. The lead mechanic at the dealership said the auto adjusts to the driver and said the vibrations will stop at about 2500 miles. The car now has 2900 miles and it still feels like the transmission is going to fail. The vibration is uncomfortable and although the dealership said the car is safe it does not feel so.it seems impossible for a vehicle to be functioning properly with this continual erratic vibrations.
The contact owns a 2017 GMC Acadia. While driving various speeds, the transmission hesitated to shift gears and the vehicle began to vibrate excessively. There were no warning indicators illuminated. The contact referenced GMC recall number 17109 (rear differential clutch control module). The vehicle was taken to a dealer where it was diagnosed that the struts and the motor mount needed to be replaced. Additionally, field testers determined that the vehicle was operating normally. The vehicle was repaired, but the failure recurred. The manufacturer was notified of the failure, but did not assist. The manufacturer stated that the vehicle was operable. The approximate failure mileage was 209,000.
On 2017 Acadia with it's 6txx transmission, the shifts from 2-3 feel weird (especially) when driving at slow speeds. You get a feeling as if tranny takes more than usual time to engage into 3rd gear, when already disengaged from 2nd gear. This is similar to what feeling one might get if you moved from 2nd - neutral - 3rd gear. I started experiencing this issue from approx. 5K miles. This would be risky when you are trying to merge into a yield or change lanes and this shift occurs, you momentarily feel loss of control. A quick google search on this issue and you will see folks already complaining about this on forums.
