Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The driver noticed that the headlight adjuster was broken. This caused poor visibility while driving at night. The consumer took the vehicle to the dealer and was informed that the headlights adjuster needed to be replaced. The headlights were not high enough to shine on the road to allow the consumer to view the road. The lights would only go about 15-20 feet in front of the vehicle.”

NHTSA complaint #10074320, filed 2004-06

“After failure, Bmw tells you to buy new headlight buckets for $650 with new adjusters in them, which will fail again after two to four years, depending on the mileage. After failure the lights shine extremly low without covering the street in front of you, resulting in a real safety hazard.”

NHTSA complaint #760922, filed 2002-04

“Consumer states the convertible headlights knob are not functioning correctly mechanic and manufacture have been notified however to resolve problem manufacture has offered to replace the whole lights for $400.00 per lights. Nlm”

NHTSA complaint #8007957, filed 2002-04

“Both headlight adjustment mechaisms have repeatedly failed. This is an ongoing complaint with Bmw 8 series owners. When the adjustment mechanism fails the headlight buckets point downwards so that the amount of road visible to the driver is 25 feet or less. Bmw has a fix for this which consists of peening a plastic adjustment wheel to the adjustment shaft. This usually fails within several thousand miles. Bmw then says to buy a new headlight bucket... $4-500 to fix a $2.00 part. …”
