NHTSA Complaint #11684500 — 2020 CHEVROLET BLAZER

On multiple occasions, my 2020 Chevrolet Blazer RS has failed to recognize when it is shifted into the "Park" gear. When this occurs, a "Shift to Park" message appears on the dashboard, and the vehicle's electronics will not shut down, preventing me from turning off and locking the vehicle. This defect presents several critical safety hazards: Inability to Secure Vehicle: The engine/electronics remain active, preventing the vehicle from being turned off and secured. This could drain the battery, leaving me stranded, or make the vehicle a target for theft. Driver Distraction: The warning message has appeared randomly while the vehicle is in motion, creating a serious and unexpected distraction for the driver. Potential Rollaway Risk: This failure in the system that confirms the vehicle is in Park could lead a driver to exit the vehicle believing it is secure when it is not, creating a potential for a vehicle rollaway. On 05/02/2024, I had the vehicle serviced for this specific issue. The dealer replaced the transmission shifter and control assembly at my expense, refusing to cover it under the powertrain warranty. The manufacturer (General Motors) is aware of this widespread defect and has issued Technical Service Bulletins (TSB #MC-10199243-9999) about it, yet they fail to treat it as the serious safety issue it is. This component failure should be investigated for a formal safety recall before it leads to an accident, injury, or death.
