NHTSA Complaint #11586369 — 2020 CHEVROLET BLAZER

Intermittent Shift to Park Message Displayed While Vehicle in Park. I am seeing an intermittent Shift to Park message when the vehicle has been shifted into Park, and the ignition has been turned to the Off position. My car model is a push-to-start/stop ignition type and this issue prevents me from turning off the car at times. I am having the vehicle serviced currently at my local chevrolet dealership but being subject to a diagnostic fee of $175. A message shows up on the instrument cluster screen stating "Shift to Park," however, the shifter is already in the Park position. Potential cause: The cause of the condition may be that the park switch in the transmission control (shifter) assembly is not pulling the BCM signal low to electronically show that the vehicle is in the Park position.
