A Preliminary Evaluation like PE88046 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: "SUMMARY: HEADLAMP SWITCH RETAINING BEZEL CRACKS CAUSING HEADLIGHTS TO REMAIN ON AND OCCASIONALLY FLICKER OFF. FORD HAS ISSUED A TECHNICAL SERVICE BULLETIN, ARTICLE # 87-11-8, TO REPLACE THE FAULTY BEZEL WITH AN IMPROVED..."

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.
