PASSENGER RESTRAINT SYSTEM FAILURE FAULT LIGHT HAS STARTED SHOWING ON MY BMW. THERE HAS BEEN A RECALL REPORTED ON THE SAME COMPONENT "STATEMENT ON VOLUNTARY RECALL INVOLVING FRONT PASSENGER SEAT SENSOR MAT ON U.S.A. MODEL BMWS - AUGUST 13, 2008". IT IS NHTSA RECALL CAMPAIGN NUMBER: 08V384000. I HAVE THE SAME PROBLEM SO I CALLED BMW AND THEY STATED THAT MY CAR IS NOT PART OF THE RECALL. I DO NOT UNDERSTAND HOW MY CAR IS HAVING THE EXACT SAME PROBLEM BUT IS NOT PART OF THE RECALL? THIS IS A HUGE SAFETY ISSUE. I THINK BMW SHOULD BE HELD RESPONSIBLE AND SHOULD BE REQUIRED TO CORRECT THIS FAULTY MAT SENSOR PROBLEM BEFORE SOMEONE IS INJURED. I AM AFRAID TO CARRY PASSENGERS IN MY CAR FOR LIABILITY REASONS. *TR
