Abs light on dash display, dealer advised had to order a module. Stopped to get gas while I was out of town and airbag deployed scaring myself and my two passengers. I was thank goodness not in vehicle. Only driverside airbag deployed and seatbelt tightened up and broke the plastic around the door frame.
