Shift to Park issue: Known issue where the car fails to recognize it is in Park, preventing it from shutting off.

I have to unplug negative cable to battery and reconnect and everything goes back to normal.
P0128 code. Coolant temperature sensor and thermostat failure.
The shift-to-park sensor in my 2019 Chevy Blazer RS is malfunctioning. After shifting into park, the vehicle does not detect that it is in park and displays a “Shift to Park” message. The issue is/has been ongoing and now it is almost impossible to bypass with wiggling the shifter. Safety Risk: The vehicle cannot be fully shut off or locked, increasing the risk of battery drain or unintended movement. This poses a safety risk if the vehicle is left in public or on an incline. Inspection History: The vehicle was taken in to the dealership in November/December 2025 due to MULTIPLE Warning Lights: “Shift to Park”, "Steering Assist", "Stabilink" and the usb-C charging port under the radio screen will stop working all together when this happens as well. This started around September 2025 and has occurred regularly since.
