When putting the vehicle in park to turn it off, the dash indicates that I need to put the vehicle in park. But it is in park and it will not let me shut off the vehicle.
While attempting to turn vehicle off, the message shift to park was given. Could not shut vehicle off! Has happened multiple times in the past, then disappears for awhile. Comes back again at will. Have seen multiple complaints on this issue falling back to a defective micro-switch within the shifter assym. Former GM tech here---

Shortly after purchasing my 2019 GMC Acadia with 52,000 miles on it, my wife parked the vehicle in our driveway and shifted the transmission into Park. When she pressed the push button to shut the vehicle off, the instrument cluster displayed a "Shift to Park" message even though the shifter was already in the Park position. Because the vehicle did not recognize that it was in Park, it would not shut off completely. The radio remained on, and the doors could not be locked. The only way to get the vehicle to shut off was to repeatedly shift from Drive to Park until it finally recognized Park…
Thermostat in these are all bad and everyone keeps having problems with them. Also forward collision warning and steering stability warning come on. Thermostat needs to have recall. Everyone is having the same problems.
My Temp control sensor is causing my check engine light to come on. After reviewing the problem, It seems many owners have had this same problem nation wide. I,m simply adding to the complaints by other owners that this should be a recall problem since so many owners are having this same problem. I,ve only had this car for 2 weeks & like the vehicle very much but this is a per the mechanic that may be caused by the sensor being placed too close to the exhaust without better protection from the heat. Please take this into consideration & hopefully come up with an adequate protective cover
Headlights are so dim that we will not drive the car at night. Dealer's service manager says that he knows about the problem but "there's nothing I can do to fix it". I see a few similar complaints on this site, but nothing as to who to contact to get the problem solved NOR any action on this on the part of the NHSTA. Where do we go from here?
