NHTSA Complaint #10467674 — 2006 BMW 530XI

THIS BMW 530XI WAGON SUFFERED A COMPLETE ELECTRICAL FAILURE AFTER THE SUNROOF DRAINAGE SYSTEM DRAINED RAIN WATER INTO THE COMPARTMENTS WHERE THE BATTERY, FUSES, VARIOUS WIRING HARNESSES AND COMPUTER MODULES ARE STORED. APPROXIMATELY 7 HOURS AFTER THE RAIN STORM, THE OWNER (WITH NO KNOWLEDGE OF THE IMPROPERLY DRAINED WATER) ATTEMPTED TO OPERATE THE VEHICLE. DURING THE DRIVE, THE CAR DISPLAYED TWO SYSTEM MALFUNCTIONS, FOLLOWED SHORTLY THEREAFTER BY THE MESSAGE "ELECTRONIC SYSTEM MALFUNCTION. CONTINUED DRIVING NOT POSSIBLE" AND MULTIPLE WARNING LIGHTS AND SOUNDS. THE CAR WAS PARKED IN A SAFE AREA AND LATER TOWED TO THE BMW DEALER. THE BMW DEALER CONFIRMS THAT THE SUNROOF DRAINED RAIN WATER INTO THE ELECTRONICS COMPARTMENTS, SHORTING OUT AT LEAST FOUR COMPUTER MODULES, AND DESTROYED THE BATTERY AND MULTIPLE SWITCHES, RELAYS, AND WIRING HARNESSES. CERTAIN SYSTEM COMPONENTS, INCLUDING AN AIR BAG CONTROL UNIT, SHOWED EVIDENCE OF A FIRE (PRESUMABLY DUE TO A SHORT CAUSED BY THE RAIN WATER.) THE BMW DEALER STATES THAT REPLACING ELECTRONICS MODULES AND THE BATTERY (APPROXIMATELY $4,000) ARE REQUIRED BEFORE FURTHER DIAGNOSTICS CAN BE PERFORMED TO DETERMINE IF THERE IS DAMAGE TO OTHER VEHICLE COMPONENTS. *TR
