Cadillac SRX radio remains on after ignition is turned off on Cadillac SRX

Some Cadillac SRX owners report experiencing issues with the radio remaining on after the ignition is turned off. This problem may stem from a faulty door switch that fails to signal the vehicle's computers that the door has been opened, preventing the radio from turning off as expected. Additionally, some owners find that the ignition switch and ignition cylinder/key may be malfunctioning, which can affect the radio's operation after the car is shut off. If the radio stays on for longer than the typical 10 minutes, there could be an issue with the window regulator/motor, as this component is linked to the signal sent to the body control module regarding door status. Furthermore, problems with the door ajar sensor or switch may also contribute, as a malfunctioning sensor may not detect that the door has been opened. To resolve these issues, it is recommended that owners inspect the head unit wiring, check the ignition components, verify radio settings, and test the door sensor for accurate functionality.
