I have a 2003 gl sedan. At one point, when i cut my car off, my headlights and instrument panel all stayed on until i opened the door, which is what it is supposed to do. well for some reason, they would go off when i opened the door, but when i closed the door, everything would come back on like i still had the car on. And i would get a message come across my stock cd player that said "calibrate". I took the car to the shop and they could never find out anything. do you know what this could mean?
