I own a 2023 BMW 330i xDrive. The factory passenger-side/right-front inner LED daytime running light has failed while the other headlight functions continue to operate normally. The vehicle has not been involved in a collision, the headlight has not been physically damaged, and no aftermarket DRL or headlight components have been installed. The affected factory BMW/HELLA right-front headlamp is BMW part number 63 11 7 886 944 (63117886944), with HELLA number 7886664-03 and HELLA assembly number 1EX 016.437-46. I was advised that correcting the failed integrated DRL may require replacement of the complete headlight assembly rather than replacement of a simple bulb or inexpensive serviceable lighting component. This makes the repair extremely expensive. Even used OEM assemblies can cost close to $2500+, while a new OEM headlight, labor, programming/coding, and related components can make the total repair cost substantially higher. I am concerned that an integrated LED daytime running light is failing prematurely and potentially forcing owners to replace an entire expensive headlight assembly because one DRL element has stopped functioning. I have also seen reports from other BMW owners experiencing similar DRL and LED headlight failures. BMW has previously issued technical service information involving LED daytime running light/headlight failures on BMW vehicles where the affected headlamp and LED module required replacement. Because this is an exterior lighting component intended to improve vehicle visibility and because the failure can result in a very costly headlight replacement, I believe this issue should be reviewed as a potential recurring defect. I am requesting that the federal safety agency compare this complaint with other exterior-lighting, headlight, and daytime-running-light complaints involving 2023–2024 BMW 3 Series/G20 vehicles and determine whether there is a pattern of premature DRL failure that warrants a defect investigation or safety recall.

What owners say
The contact owns a 2020 BMW 330i. The contact stated that the headlight housings would become foggy whenever it rained. The contact stated that the failure had caused the low beam lights to be diffused and to fail to illuminate the roadway beyond 15-30 feet. The vehicle was taken to the dealer with photos of the foggy headlight housings, but the dealer informed the contact that they could not replicate the failure because the headlight housings were clear the time. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000.
I have heavy condensation in my BMW 330i xDrive driver side headlights. Comes during rainy and moist weather and takes couple of days to go away. upon dealer inspection its underlying issue with BMW's and sadly my warranty just expired 5 months ago and BMWusa is not helping in this regard.
Excessive moisture or condensation in the headlights after heavy rain. First one failed which is on driver side but replaced but second one which is the passenger side failed too within months. Replace for headlights would cost 4.5K
When driving the car when dark enough to activate auto headlights and raining enough to activate auto wipers, after 20 minutes the following message comes on the screen EVERYTIME: Drive Assistance temporarily limited Lane departure also turns on and off while driving in these conditions Also attached are BMW's response after inspecting the car on 3 separate occasions
This car has factory HID Xenon projector headlights. Over time the reflector bowls burned and melted from the heat of the light bulbs, causing some wire insulation to melt, and a brown film to cover all surfaces inside the headlight assembly. The brown coating makes the headlights dangerously dim. From various online searches, it appears this is a common failing of these headlights. BMW has not recalled these headlights, and replacements nearly exceed the value of the car.
Engine Wiring is made of Soy products with attracts Rodents to feed and destroy the wiring. When this occurs it puts the driver ad passengers in danger because certain functions such as brake light, Headlights and windshield wipers may not work properly. This is becasue when the wiring is compromised , circuits are broken which causes the vehicle's systems connected to that circuit to partially or completely fail, Rending a vehicle partially or completely inoperable. The vehicle was inspected the the BMW dealership service center and they confirmed it was rodent damage . Geico insurance also inspected the vehicle. The vehicle started to restrict engine performance and the Engine service light came on stating there was a Drive Tran malfunction.
The contact owns a 2020 BMW 330i. The contact stated that while he was sleeping, the vehicle was parked outside of the garage and had started itself without the key in the ignition then drove itself and crashed into the aluminum garage door. The contact was aware of the failure when he went inside the garage and heard the engine running but could not open the garage door. When the contact went outside, he saw that the vehicle had crashed into the garage door with the engine still running and the headlights were on. A police report was filed. The dealer was contacted but had not returned the contact's phone call. The vehicle was not diagnosed nor repaired. The manufacturer was not made aware of the failure. The failure mileage was 17,218.
Right front low beam headlamp cuts out intermittently and eventually stops working due to cracked wiring inside the adjustable headlamp unit. For awhile, my headlight would stop working while making a right turn but then turn back on when straightened out. After two right turns, the headlight would cease to turn back on. Now (after several weeks of this happening) the headlight does not function at all, and I can see broken wiring if I look inside the headlight unit causing the issue.
The interior wires of the bmw e46 headlight assemblies have insulation material that readily breaks off of the wire, causing the bear wire conductor to be visible. This results in a failure of the headlights as the wires conductors are allowed to touch. This is also a possible source of a vehicle fire.
