NHTSA Complaint #10668830 — 2006 BMW 530XI

FAILURES OF MULTIPLE WIRES/ELECTRICAL COMPONENTS IN THE TAILGATE/REAR WINDOW WIRING HARNESSES. SEARCH FOR BMW E61 TAILGATE WIRING PROBLEMS. THE FAILURES ARE CAUSED BY A POOR DESIGN WHERE THE WIRES ENTERING THE HINGE GUIDES (4) FOR THE GLASS AND TAILGATE ARE REPEATEDLY FLEXED AT A SHARP ANGLE UNTIL THE INSULATION, THEN THE COPPER WIRE BREAKS. SAFETY ISSUES - POSSIBLE ELECTRICAL SHORT CIRCUIT LEADING TO FIRES (HIGHEST LOAD IS FOR REAR DEFROSTER); LIGHTING FAILURES (REAR HIGH BRAKE LIGHT, LICENSE PLATE LAMPS AND OTHERS); REDUCED VISIBILITY DUE TO LOSS OF WIPER/WASHER/DEFROSTER; REAR GLASS LATCH OPENING WHILE UNDERWAY, POSSIBLY RESULTING IN LOSS OF CARGO OR INGRESS OF EXHAUST FUMES. THIS IS NOT AN EASILY REPAIRED PROBLEM AND HAS COST OVER $2000 SO FAR. I'M WORRIED ABOUT DRIVING THIS CAR AS IT IS THE MAIN TRANSPORTATION FOR MY CHILDREN AND THEIR FRIENDS.I DISCOVERED IT WHEN THE REMOTE LOCK/UNLOCK USING THE KEY FOBS FAILED, THE TRUNK INOPERABLE AND UNCLOSEABLE, THE RADIO STOPPED WORKING, THE LIGHTS IN THE REAR OF THE CAR STAYED ON PERMANENTLY AND I HAD TO DRIVE HOME ONE NIGHT WITH THE TRUNK WIDE OPEN BECAUSE THE WIRING HAD STOPPED WORKING AND IT COULD NOT BE CLOSED. AS I INVESTIGATED I FOUND MANY BROKEN GROUND WIRES, ALONG WITH SEVERAL OTHERS WITH BROKEN INSULATION, SOME WITH BROKEN COPPER STRANDS ETC. I HAVE ALREADY HAD THE RIGHT AND LEFT WIRE HARNESSES REPLACED AT AN INDEPENDENT DEALER FOR ABOUT $2200. THIS IS A SAFETY ISSUE AND I'M WORRIED THAT MORE WILL COME. *TR
