   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---

   Problem 1: I got the car 2 years ago, and it keeps telling me to "Shift to Park" even though its in park. That's been happening for the whole time I've had it. It does throw a code for it on the scanner machine. I have to shift it back and forth sometimes 3 times and sometimes 17 times. It just keeps beeping over and over and won't shut off. I am having a mechanic look at it Tuesday but hoping it doesn't cost a lot. But no recalls on my car. Problem 2: For the last 4 months…

   When I shift my 2019 GMC Acadia into park, the warning message reads shift to park and there is a ding warning that plays for several mins. This has been going on for over a year. I took it to the dealership and they said they could repair it for $1000 dollars but the solenoid was only guaranteed for 30 days. There is no possible way a dealership can expect a person to pay $1000 dollars a month to keep their family and transportation safe.

    Park to shift issue - the vehicle did not register that I was in park, jerked hard when trying to place in gear, did not register the PROPER gear (reverse, neutral, drive), would NOT unlock doors to let passengers out even if it were an emergency. Seems to be triggered on inclines but have also been having issues on flat ground. Other Acadia's apparently have a recall for this issue but my VIN does not register as recalled which is not acceptable.…
