“Message on Console - Passenger Restraint system malfunction . Took vehicle in for Repair; BMW Dealership thinks it may be a wiring harness electrical short. They evidently need to discuss problem with BMW Corporate to figure out to properly diagnose problem and how to repair. My husband and I are very concerned about driving this car even after it may be so called repaired. We are concerned that if an accident does occur, and one or more of the airbags do not deploy; there may be serious injury or death to myself, my husband, grandkids, or other passengers.”
