passenger door locks. car is running and the driver gets out leaving car on and then the passenger turns off the car and gets out, locks car, the radio stays on. i went inside the store and came out and the radio was still playing. when you unlock the car but enter only the passenger front door and then close it and walk away, the car locks itself. happened several times. i had not placed the keys on the seat of the car and shut the door or i would have been locked out. i reported this but no one seemed to care. radio was replaced for left button paint
