When there is a passenger sitting in the front passenger seat, sometimes the 'airbag off' indicator light will go on randomly. i even have video proof of this happening while my girlfriend, weighing 130 pounds, was sitting in the front passenger seat with her seatbelt on. the light would stay on for minutes, sometimes an hour, before randomly turning off. also, the engines oxygen sensor randomly triggers the 'service engine' light as well, i believe it needs to be reprogrammed.
