The idrive system in my car continues to cut on and off, this eventually caused my car to shut off on me two times while in traffic with no warning or indication of the shut off. The sensor alert continuously goes off for everything in the car. I took my car to the BMW dealership in Huntsville Alabama, they had my car for almost a month and could not find the issue with the drive or anything the sensors were notifying me of. The system constantly says my car is overheating, but I just got the radiator hose fixed and the dealership checked it for leaks while they had it and they did not see any other leaks or any other issues causing it to overhear. I researched this issue on a BMW form and… - Aug 3, 2018Seats

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…
