Yesterday something wierd happened, when I push the button to turn off the car, the beep-beep-beep-beep starts even though the hands free is not in the slot, it's in my pocket. This morning it is still doing the same thing and now the driving lights (which I keep on "Auto") stayed on after I locked the car. A colleague told me about it 40 minutes after I left the car. Has this happened to anybody before? A way to fix it? Thanks!
