Consumer Description
The transmission shift control / transmission range sensor / shift interlock solenoid in my Chevrolet Trailblazer is malfunctioning. When I shift the vehicle into park, it fails to recognize the gear change and displays an error message stating, “Shift to Park.” As a result, I'm unable to shut off the engine properly, which poses both a safety risk and a serious inconvenience. I strongly urge the NHTSA to investigate this issue thoroughly and consider issuing a recall to address the defect.
