NHTSA Complaint #10293486 — 2003 LINCOLN LS

ON A 2003 LINCOLN LS, THE BRAKES HAVE FAILED TO ENGAGE PROPERLY ABOUT A DOZEN TIMES OVER THE PAST 2 YEARS. EACH TIME, THE PAVEMENT IS DRY AND FREE OF DEBRIS OR GRAVEL. WITH EACH INCIDENT, THERE HAS BEEN A 25%-75% LOSS OF BRAKING POWER WITH A GRATING, OR METAL-ON-METAL, SOUND COMING FROM THE FRONT END. WE HAVE BROUGHT THE CAR TO THREE DEALERSHIPS AND ONE INDEPENDENT MECHANIC TO TRY TO RESOLVE THIS, BUT NONE HAVE BEEN ABLE TO FIND THE PROBLEM. WITH EACH INCIDENT, THE CAR HAS NOT ILLUMINATED ANY WARNING LIGHTS, NOR HAVE THE LIGHTS INDICATING ENGAGEMENT OF ABS/TRACTION CONTROL ILLUMINATED. THE OBDII MODULE HAS NO CODES RELATED TO THESE FAILURES. ALTHOUGH WE HAVE HAD NO INJURIES DUE TO THIS, TWICE NOW THE CAR HAS BEEN UNABLE TO STOP AT STOP SIGNS AND GONE COMPLETELY THROUGH AN INTERSECTION. WE HAVE BEEN UNABLE TO DETERMINE WHAT CONDITIONS TRIGGER THE BRAKE FAILURE. RESEARCH ON THE INTERNET (SEARCHING "LINCOLN LS NOISE BRAKES" OR "LINCOLN LS BRAKE FAILURE") INDICATE A NUMBER OF OTHER PEOPLE WITH THE SAME SYMPTOMS, AND IN EACH CASE, IT APPEARS NO MECHANICAL CAUSE HAS BEEN FOUND. *TR
