Warning lamps for stability control air bag randomly light up on my dash board panel. The passenger air bag will also switch to off even when a passer is sitting in the seat or the passenger seat belt warning sound will go off if a small object is placed on the seat. My mechanic can't find the issue as I cannot recreate the circumstances that cause the lamps to switch on or the warning siren to chime. Computer readings do not return any "codes" if the lamps aren't on.
