NHTSA Complaint #11626823 — 2021 CHEVROLET TRAILBLAZER

When I place my car in park, a "shift to park" message appears on the dashboard. I am unable to fully turn my car off and the car will ding at me. I have tried driving around the parking lot, pushing the shifter from side to side and into another gear then park again, going forward and backward, but the problem still exists. It started to occur more frequently, until it occurred every time I drove the car. I'm not sure if the car is actually in park, so when I finally get it to turn off, I place the emergency brake on. I can not physically turn the car off when this message appears on the dashboard. I took the vehicle to the service center of the dealer on 11/12/2024. I was told this has been a big problem with GM cars and they have had many cars coming in with the same problem. Currently the part is on backorder, and there is not an ETA as to when it will be available due to high demand for this part.
