So once in a while, after I park my car, turn it off, then open my door, the inside of the car would beep, as if I were to leave with the lights still on, except my lights are off. On the MID screen, there are no error messages. Sometimes it's one long beep (about 1.5 seconds) Occasionally it will be just repeating short beeps. Doesn't happen all the time, just once in a while. I have no idea what the beeps are. Anyone have any ideas?
