PASSENGER SIDE HEADLIGHT ASSEMBLY WIRES BREAK AND CAUSE THE HEADLIGHT TO STOP EMITTING LIGHT OR OTHERWISE WORKING. REPEATED ATTEMPTS TO REPAIR THE WIRING HARNESS EVENTUALLY FAIL. THIS OCCURS WITH MERE NORMAL USE OF THE CAR AND PASSAGE OF TIME. THE HEADLIGHT ASSEMBLY AND BULB ARE STILL INTACT, BUT SIMPLY RECEIVE NO POWER DUE TO THE BROKEN WIRES. THE ASSEMBLY CAN FAIL AT ANY TIME, WHETHER STATIONARY, IN MOTION, OR ON BACK ROADS OR HIGHWAYS.

Owner report 10345568 · 2010-07-27 (July 27, 2010)
THE TAIL LIGHTS ON BOTH SIDES OF MY 2004 BMW 330I HAVE STOPPED WORKING COMPLETELY (NO TURN SIGNAL OR BRAKE LIGHTS) DUE TO A BURNED WIRE. THIS BEGAN ON THE LEFT SIDE WITH THE TURN SIGNAL LIGHT GOING OUT. WHEN I WENT TO CHANGE THE BULB, I REALIZED THE BULB WAS FINE. LOOKING CLOSER I SAW THAT A WIRE IN THE WIRE HARNESS HAD BURNED AND MELTED THE PLASTIC. IT ALSO MELTED THE METAL ON THE TAIL LIGHT ASSEMBLY. THIS WAS A COUPLE MONTHS AGO THAT THIS HAPPENED AND NOW THE RIGHT SIDE HAS DONE THE EXACT SAME THING. I CALLED THE DEALER AND WAS TOLD THA…

Owner report 11128565 · 2018-09-10 (September 10, 2018)
THE STOCK ZKW PROJECTORS HAVE BURNT OUT AND SIGNIFICANTLY REDUCE THE QUALITY OF LIGHT EMANATING FROM THE HEADLIGHTS. IN ORDER TO HAVE ANY TRUE VISIBILITY, I HAVE TO HOLD THE "FLASH-TO-PASS" LIGHTS ON WHILE I'M DRIVING (A MANUAL TRANSMISSION). THIS IS OBVIOUSLY A DANGEROUS SITUATION. THE REPLACEMENT ASSEMBLIES ARE OVER $3,000 FOR THE PAIR. THAT COST CANNOT BE JUSTIFIED. I PURCHASED THE CAR A COUPLE OF MONTHS AGO, BUT I, OF COURSE, DID NOT TEST DRIVE IT AT NIGHT (SINCE IT WAS SUMMER). SO I HAD NO WAY OF KNOWING ABOUT THE DETERIORATED CONDIT…

Owner report 10437377 · 2011-11-27 (November 27, 2011)
2003 AND 2004 3 SERIES MODELS WITH XENON HEADLAMPS MANUFACTURED BY ZKW HAVE A DEFECT IN WHICH THE HEAT FROM THE XENON HEADLIGHT BULBS ARE MELTING THE PLASTIC PROJECTORS OR REFLECTOR BOWLS. THIS CAUSES A DRASTIC REDUCTION IN PROJECTED LIGHT. THE FIRST SIGN OF THE PROBLEM IS DISCOLORATION OF THE CHROME COATED PLASTIC REFLECTOR BOWL. EVENTUALLY THE REFLECTOR BOWLS SHOW SIGNS OF MELTING. IT SEEMS THE CAUSE IS LIKELY A COMBINATION OF THE XENON BULBS BEING TOO CLOSE TO THE PLASTIC REFLECTORS AND OR THE PLASTIC'S HEAT RESISTANCE IS NOT HIGH ENOUGH. IN…
