NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA96-019.

EXCESSIVE HEAT IN AN IMPROPERLY MANUFACTURED CIRCUIT BREAKER WITHIN THE HEADLIGHT SWITCH CAUSED THAT CIRCUIT BREAKER TO OPEN FOR TIME PERIODS OF VARYING LENGTH TO COOL OFF.OPENING OF THE CIRCUIT BREAKER IN THIS MANNER INTERRUPTS ELECTRIC CURRENT FLOW TO THE HEADLIGHTS, SHUTTING THEM OFF.HEADLIGHT OUTAGES HAVE RANGER FROM BRIEF FLICKERS (LESS THAN ONE SECOND) TO GREATER THAN 20 SECONDS.OVER TIME, THE OUTAGES GROW IN LENGTH AND DURATION BECAUSE OF HEAT-INDUCED DETERIORATION OF THE SWITCH AND ASSOCIATED WIRING.RECALL 98V-009 WILL APPLY TO APPROXIMATELY 506,000 TAURUS, SABLE, MARK VIII, AND CONTINENTAL VEHICLES PRODUCED FROM 1-DEC.-92 THROUGH 30-SEP-93 AT THE ATLANTA, CHICAGO,AND WIXOM ASSEMBLY PLANTS.87% OF MY 1992-1995 TAURUS/SABLE AND 97% OF MY 1993-1995 MARK VIII WARRANTY REPAIRS (HEADLIGHT SWITCH REPLACEMENT) INVOLVED VEHICLES BUILT DURING THE DEC. 92 - OCT. 93 BUILD RANGE.

Vehicles and equipment listed for this investigation

What an NHTSA investigation is

NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.

An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
