ok, i thought i fixed the problem but apperantly not. sometimes when i have a passenger in my car on the front seat, the service airbag comes on and when i turn my car off and back on, it goes away and comes back another time. it never comes on when im alone but when someone sits on it. could something be loose for the seat sensor? could it be easily fixed w/out going to the dealership? its hasnt been a problem for a while before now since the last time it happend.
