2008 BMW 528I Seats Problems

MY SEAT WAS SMOKING AND SOON TO CATCH FIRE IF I HADN'T CAUGHT THIS. WHAT SHOULD I DO TO RESOLVE THIS ISSUE?

AIR BAG SENSOR FOR FRONT PASSENGER SEAT NOT WORKING. REPLACED ONCE WHILE VEHICLE UNDER WARRANTY. SAME SENSOR MALFUNCTION AGAIN. BMW WILL NOT REPLACE UNLESS I PAY, COST OF REPLACING SENSOR OVER 4,000.00. I BELIEVE IT SHOULD BE COVERED BY BMW SINCE SAME PART IS AGAIN NOT WORKING.

I WAS DRIVING MY CAR AND SUDDENLY THE RESTRAINT SYSTEM MALFUNCTION LIGHT TURNED ON AND THE SEATBELT LIGHT TURNED ON. I DID NOT HIT A BUMP OR ANYTHING. THERE WAS NO PASSENGER CURRENTLY SITTING ON THE PASSENGER SEAT WHEN THE LIGHT CAME ON. I HAVE TRIED SITTING DOWN ON THE PASSENGER SEAT AND PUT ON MY SEAT BELT TO SEE IF IT WILL GO AWAY BUT NO LUCK. ALSO, THE SEAT BELT LIGHT WILL NOT GO AWAY EVEN IF I BUCKLE THE DRIVERS SEAT AND PASSENGER SEAT BELT. *TR

UPON TURNING THE SEAT HEATER ON I NOTICED A BURNING SMELL AND SMOKE INSIDE THE CAR. THE SEAT WAS UNUSUALLY HOT. I FELT A BURNING SENSATION AND PULLED OVER TO FIND THAT THE SEAT HEATING ELEMENT HAD BURNED THROUGH THE LEATHER AND TWO LAYERS OF A HEAVY DUTY WINTER COAT. WHEN I TURNED IT OFF THE SMOKE STOPPED. WE TOOK THE CAR TO THE BMW DEALERSHIP AND WAS TOLD IT IS NOT PART OF A SAFETY RECALL OR UNDER WARRANTY. REFUSED ANY MONETARY CONSIDERATION AND WANTED $1400 TO REPAIR. CONSIDERING THE CAR COULD CATCH ON FIRE THE REPAIR SHOULD BE CONSIDERED A SAFETY ISSUE AND REPAIRED FOR FREE. *TR
