Example complaints

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

“The contact stated while driving at night, the head lights were not bright enough due to the lenses clouding and looking milky. The vehicle was driven to the dealer, who determined the head lights needed to be replaced. The contact replaced the head lights. Updated 01/10/07.”

NHTSA complaint #10175438, filed 2006-12, 165,000 miles

“Every time vehicle is driven with the headlights on, headlights flicker on and go off. Vehicle has been taken to the dealership four times in a six-month period. Dealer was not able to fix the problem. Also, doors are warped/engine runs rough/replaced differential/brakes are locking up.”

NHTSA complaint #859969, filed 2000-04

“The lampholder assembly has printed-wiring sheet to route current to bulb sockets. During manufacture, this circuit layer is mounted to the structure of the lamp holder assembly with a plastic riveting process. A (plastic and thus non-conducting) rivet passes *through* a conductor common to the brake and turn lamps, nearly severing the conductor. Eventually the small thread of remaining conductor fails entirely, resulting in a lack of safety signalling that can not be repaired by bulb replacement. …”
