NHTSA Preliminary Evaluation PE04020 - closed, opened 2004-02-26 and involving the NISSAN NISSAN.
NHTSA investigation PE04020 is a Preliminary Evaluation opened on 2004-02-26 and currently closed. The subject of record is NISSAN NISSAN, which places this file inside the Office of Defects Investigation queue for NISSAN. Latest activity on this investigation was logged on 2004-06-24 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE04020 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "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 FLI..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related NISSAN files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
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.
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
