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.

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

My 2018 GMC Acadia has warning of shift to park. When it is in park. And will not allow me to turn off the car. I feel this is a major issue. This only happens when it is stationary.

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.

Exploded sunroof - the sunroof exploded when I was not in the car. I heard the glass falling in to the sun shade when I closed the door. Took me several days to recognize and figure out what the sound was. No rocks, no sign of anything falling on the roof to damage. The glass appeared to be pushed out as can be seen on the photos.
