NHTSA Complaint #10199408 — 2003 BMW E36

THERE IS A SERIOUS ELECTRICAL PROBLEM ON MANY BMW E46 MODELS (NEWER CARS). THE TAIL LIGHT HARNESS ON BOTH SIDES HAS WHAT SEEMS TO BE A FAULTY, INCOMPLETE, OR INSECURE GROUNDING WIRE AND THE RESULT IS THAT THE WIRE OVERHEATS AND CORRODES, AND IN SOME CASES ARCS, WHICH CAN IGNITE A FIRE. THE PROBLEM IS OFTEN IDENTIFIED BY INTERMITTENT OR PERSISTENT FAILURE OF THE REAR LIGHTS ON THE CAR AND/OR UNNECESSARY REAR LIGHT WARNINGS ON THE DASH. I HAVE PHOTOGRAPHS TO SUPPORT THIS CASE AND HAVE DONE FURTHER RESEARCH TO FIND COUNTLESS SIMILAR CASES. THE DAMAGE IS MOST OFTEN CHARACTERIZED BY CHARRED DISCOLORATION OF THE BROWN (GROUND) INSULATOR AND MELTING OF THE SURROUNDING PLASTICS WHICH RESULTS IN THE METAL CONNECTORS BECOMING LOOSE. THE REPAIR OF THE PROBLEM WOULD MOST LIKELY CONSIST OF AN UPGRADED REPLACEMENT OF THE WIRING HARNESS. FURTHER WORK INTO THE ELECTRICAL DISTRIBUTION SYSTEM MAY BE NECESSARY DEPENDING ON THE CAUSE OF THE FAULTY GROUND. *TR
