| Investigations Summary: | This investigation was opened on Feb. 26, 2004. It was closed on Jun. 24, 2004. Nissan and Ford found that the original equipment headlight stainless steel bulb terminals may over time cause elevated contact resistance and overheat the electrical connector housing. This can result in a headlight flickering, bulb outage and heat deformation to the headlight connector. In April 1999, the supplier of the headlight for Nissan and Ford changed to a bulb using the stainless steel terminals that did not meet original specifications. On July 17, 2000, the supplier began using a bulb meeting the vehicle manufacturer's specifications. This problem can affect independently either headlight but does not cause simultaneous failure of both headlights. The problem also does not affect front parking lamps. As a result, the complaints typical report single failure of one headlight. There are no crashes or loss of vehicle control reported. A safety-related defect trend has not been identified at this time and further use of agency resources does not appear to be warranted. The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. The agency reserves the right to take further action if warranted by the circumstances. |
