THE FARS DATA SHOWS THAT THE RISK OF FIRE FROM IMPACT IN ALL DIRECTIONS IN THE SUBJECT VEHICLES IS THE SAME AS ALL OTHER SEDANS.THE SUBJECT VEHICLES ARE NOT OVER REPRESENTED WITH RESPECT TO THE RISK OF FIRE IN REAL-WORLD HIGH-ENERGY CRASHES.A FURTHER DISCUSSION OF ISSUES RELATED TO POST CRASH FIRES IN THE SUBJECT VEHICLES IS SET OUT IN THE CLOSING REPORT FOR SQ 01-014 AND THAT REPORT IS IN THE DOCKET FOR THIS PETITION.AFTER REVIEWING THE PETITION AND ITS SUPPORTING MATERIALS, AS WELL AS INFORMATION FURNISHED BY FORD AND GM, AND INFORMATION WITHIN THE AGENCY'S POSSESSION FROM PREVIOUS INVESTIGATIONS AND OTHER RELATED ACTIONS,NHTSA HAS CONCLUDED THAT FUTHER INVESTIGATION CONCERNING POST-CRASH FIRES IN THE SUBJECT VEHICLES IS NOT LIKELY TO LEAD TO A DECISION THAT THE VEHICLES CONTAIN A SAFETY DEFECT.

MY HEADLIGHTS, HAZARDS, AND TURN SIGNALS ALL JUST RANDOMLY WENT OUT WHILE DRIVING. THEY HAVE NOT COME BACK ON SINCE. AFTER READING FORUMS I BELIEVE IT TO BE THE LCM BUT MY YEAR MODEL IS NOT INCLUDED IN THE RECALL. I BELIEVE THIS ISSUE DATES BACK FARTHER THAN 2000 AND FORD SHOULD STEP UP AND RECALL MORE OF THESE LCM COMPONENTS.
