ALLEGED HEADLIGHT FAILURE

What NHTSA is examining

A total of 646,038 subject vehicles were sold during my 2001-2003, and the complaint and warranty data tabulated above apply to the total vehicle population.complaint reports alleging headlight outage represent slightly more that one-half of the total number of complaints and the balance are allegations of flickering and dimming.investigation disclosed the root cause of the malfunction to be wear of a contact plunger in the multifunction switch that may result in a temporary open circuit, with the plunger in a neutral position between high- and low-beam contact points.consumers consistently reported that manipulation of the switch handle on the steering column restores either high or low beam headlight function.no other potential safety related issues, e.g., fires or windshield wiper failure, were found to be related to this issue.the manufacturer recognized the subject headlight issues from failure and warranty reports, and issued a redesigned plunger in 2003. The manufacturer did not identify a defect requiring recall and remedy.odi has determined that the rates of occurrence, the failure mode and the real-world consequence of the alleged defect as compared to other similar investigations fail to identify a safety-related defect trend.this preliminary evaluation has been closed.the closing of this investigation does not constitute a finding that a safety-related defect does not exist.the agency may take further action if warranted by the circumstances.
