NHTSA Complaint #10488120 — 2007 BMW 3 SERIES

THE BMW 3 SERIES (MINE INCLUDED) IDENTIFIED BY CHASSIS DESIGNATIONS E90, E91, E92, AND E93 (ALL US MODELS) HAVE A KNOWN DEFECT REGARDING AUTOMATIC EXTERIOR MIRROR MOVEMENT WHEN UNLOCKING THE VEHICLE DOORS USING THE KEY FOB. THE MIRROR MOVEMENT OCCURS REGARDLESS OF WHICH KEY FOB IS PRESENTED TO UNLOCK DOORS. A SINGLE KEYFOB UNLOCK PROCESS CAN TRIGGER INNUMERABLE EXTERIOR MIRROR POSITIONS. THE UNSUSPECTING DRIVER WHO DOES NOT CHECK BOTH HIS/HER DRIVER AND PASSENGER SIDE MIRRORS PRIOR TO DRIVING THE VEHICLE WILL BE REQUIRED TO SET THE PROPER MIRROR POSITIONS WHILE DRIVING OR LEAVE THEM MALADJUSTED UNTIL THE NEXT STOP, IMPAIRING THEIR ABILITY TO SEE VEHICLES ADJACENT OR ONCOMING VEHICLES FROM THE REAR, INCLUDING EMERGENCY VEHICLES. BMW HAS ISSUED A SERVICE BULLETIN REGARDING THIS DEFECT. HOWEVER, ONLY CARS WITH EXISTING MANUFACTURER WARRANTIES ARE REPAIRED IF THIS ISSUE OCCURS. REF BMW SI B51 36 08 THE PROBLEM HAS BEEN LINKED TO CORROSION OF MIRROR MOTOR ELECTRICAL CONNECTORS. IT IS ALSO PLAUSIBLE THAT ALL ELECTRICAL ADJUSTMENT OF THE EXTERIOR MIRRORS WOULD BE RENDERED AN IMPOSSIBILITY IF THE PROBLEM ESCALATES. *TR
