Owner reports
Selected complaints filed with NHTSA by 2004 BMW 3 Series owners, lightly cleaned up (personal details are redacted by NHTSA).
Tl* the contact owns a 2004 BMW 330. The contact stated that the plastic reflector bowl used for the headlights were burned and scorched by the heat of the bulbs used on the vehicle. The contact replaced the covering before and within a year, it burned through again. The contact stated that the brand covering that was failing was the zkw brand. The vehicle was not inspected by the dealer or repaired. The failure mileage was unknown and the current mileage was 71,000.
Headlamp bulb out and upon replacement it was noted the coated wiring to the xenon system to right and left headlight is brittle (the wires plastic coating is falling off)and in some places exposed wiring was found. Electrical tape need to wrap the wiring to avoid potential fire. Late notice to this site I was unaware to file a report. Others also have complained about the same issues.
Zkw HID xenon low beam reflectors burnt or corroded causing a significant decrease in light output that BMW wants ~$3000 to fix. Lights were a premium option and cannot be corrected by xenon bulb replacement. The output has dimmed as to be unsafe.
My 2004 BMW 325ci recently developed a problem with the left rear tail light (turn signal and brake light) intermitently does not work. A left tail light failure also shows on the on board diagnostic display. The problem is intermitent and with no warning. I did some research and found there was a BMW recall for model years 2001 thru 2005 for this exact problem. The recall specifies 325 sedan models, my model is a 325ci (coupe). I called BMW north America and they say my particular model is not covered by the recall. I argued that I am having the exact same issue as the recall suggests, and my vehicle falls into the model years specified. They refused to acknoledge the problem as part of the recall. BMW issued a technical service bulletin (si b63 06 11 lights) for this issue in January of 2012. A recall (id # 71087) was issued aug. 26, 2011. …
For a little over a year now I've been noticing that at night I've been having a real hard time seeing at night while I am driving. For a while I thought it was my eyes going bad until multiple people started asking if my lights where on, ( I was like good it's not my eyes) it gets real bad especially when it rain or the roads or wet which is almost every night cause live in hawaii and it rains all the time. But of course the problem is not getting better it's gotten so bad that I have to drive with my fog lights at night. I went to the dealer thinking it was the bulbs and they said that it was not and I would have to replace the whole headlight assembly right and left. I have never heard this before so I started to search the net and come to find out that I am not the only one with this problem. Please help!
Recently purchased said vehicle and it came with zkw HID bi-xenon lighting system which appears the inner plastic bowls are burnt to a crisp with detriment light output making it almost impossible to clearly see unlit roads at night, this is a huge safety concern and needs to be reviewed and solved in a timely manner as it affects thousands of similar vehicles on the road. I'm afraid the reduced light output might appear to other drivers at night that my vehicle is further away that it is in reality giving the possibility of them crossing into my travel path incurring an accident. I know you have been reviewing this for quite some time but we need a resolution soon... Thank you.
Zkw xenon headlights equipped on the car have a plastic reflector bowl for the low beam. The OEM light bulb burns hot and melted the plastic reflector bowl. This causes a severe loss of projected light to the road. Many times I have to drive with high beams on to see more than 10-15 ft in front of the car cause me to blind other drivers. BMW nor zkw recognize this as an issue and my dealer suggested I buy a whole new headlight assembly for 1.5K (each side) to fix the issue. This should be recalled because it is a design failure. The later versions on the zkw headlights use metal reflector bowls (not interchangeable with earlier version) so the issue is know to them.
Front optional HID (xenon) headlamps were noticed a being extremely dim. The headlight has a replaceable plastic lens. Lens was first polished and then when no light improvement was observed, both lenses were replaced. Light output remain very poor. Bulb were ordered to replace original however when beginning to replace the bulbs it was noticed that the bowl had an observed scorch or burned spot on the projector bowl and I ceased changing the bowl. After reading forums it appears this is a common manufacturing defect involving a safety items that reduces viability and May possibly burn through on this model year with this option. A photo is available if necessary.
2004 BMW 325xi sedan; taillight fails intermittently according to dashboard indicator, then failed solid. The wires melted inside the connector to the light housing and melted housing post - no easy way for home repair as this is not just a bad lightbulb. BMW has service bulletin on repair, but is a pure design defect from the factory. There is no owner-induced problem here. They will not accept responsibility for repairs or recalls. A "google" reveals that this is a widespread issue with BMW 3-Series and some 5-Series cars. They should be forced to recall these cars for repairs.
As reported by other owners, the bi-xenon headlights no longer light up the road. It is a safety hazard and is a known issue with headlights manufactured by zkw on 2003-2005 BMW 330 models. The reflector bowls on these units burn out over time and reduce the headlights ability to reflect light. Driving at night is literally no better with the headlights on or off. I have to rely on my fog lights just to see anything. Please look into this safety issue as it is wide-spread. Replacement of headlights is expensive at $1300 ea, this has to be resolved by BMW immediately.
