NHTSA Complaint #11648590 — 2017 GMC ACADIA

A couple of months ago, I tried to put my car in park and shut it off the same way I have for years. The car made a rapid alarm sound and displayed a SHIFT TO PARK message on my dashboard. In order to get the car to shut off correctly, I had to squeeze the button on the shifter and gently push forward and backwards until the car recognized that I was in park. This now happens approx. 1 in every 15 times I try to turn off my vehicle. When this happens, I do not know if my car is actually in park and this is just a sensor issue or if the car is in fact struggling to shift to park!? If that's the case, couldn't it roll into someone or some thing? I remember JEEP having this issue a few years back, where people were killed when their "parked" jeep rolled over them. I think a famous actor was one of those victims in his driveway. Has GMC ever released a statement as to why only some VIN #s are included in this recall, when MANY of us on here are experiencing the same issue??
