when I put it in parking it does not recognize and the car is unable to turn off
Shift To Park message displays while vehicle is already in Park! Incident began increasing in frequency in late 2022 . Vehicle would not Shut Off! Bulletin on problem came out in 2019, Chevy did not inform me of this Safety issue , Grandchildren in vehicle at least 2 times .
I am experiencing the well know “shift to park” issue. When I move the shifter to the park position and turn off the vehicle, I receive a message stating “shift to park” and I’m unable to fully power the car off or lock the doors. This is only overcome by trying to wiggle the shifter.
My 2019 blazer when stopped and put into the park position would say on the dash shift into park so you didn’t know if it was in park or not , also it would not turn off the motor would stop but none of the electric would turn off until the battery ran down .
