WHILE DRIVING MY CAR AT IN THE VERY EARLY MORNING BOTH HEADLIGHTS FAILED ON A CURVY DOWNHILL ROAD. I SWITCHED THE HEADLIGHT SWITCH FROM THE AUTOMATIC POSITION TO THE MANUAL "ON" POSITION, BUT THE HEADLIGHTS DID NOT COME BACK ON. I PUSHED THE HIGH BEAM SWITCH FORWARD TO THE HIGH BEAM POSITION BUT THIS FAILED TO TURN ON THE HIGH BEAMS. I PULLED THE HIGH BEAM SWITCH BACK TO THE HIGH BEAM "FLASH" POSITION WHICH DID ILLUMINATE THE HIGH BEAMS. I HELD THE SWITCH BACK IN THIS POSITION (TO THE DISPLEASURE OF APPROACHING DRIVERS) UNTIL I FOUND A SAFE PLACE TO PULL OVER. I CYCLED THE HEADLIGHT SWITCH NUMEROUS TIMES WITH NO EFFECT. THE LIGHT DID FINALLY COME BACK ON THEIR OWN FOR A SHORT TIME, BUT THEM WENT OFF AGAIN. THIS HAPPENED SEVERAL TIMES UNIT THEY FINALLY DID SOME BACK ON FOR A LENGTHY PERIOD OF TIME. THE NEXT DAY THE SAME SITUATION OCCURRED. AT ALL TIMES THE OTHER LIGHTS (DASH, PARKING, ETC) CONTINUED TO OPERATE. VERY DANGEROUS. *TR

WHILE DRIVING AT NIGHT, MY WIFE PUT ON THE LEFT TURN SIGNAL AND THE HEADLIGHTS IMMEDIATELY FAILED, CREATING A DANGEROUS SITUATION. SHE FRANTICALLY FIDDLED WITH VARIOUS LIGHT CONTROLS UNTIL FINALLY DISCOVERING THAT BY MANUALLY HOLDING THE "FLASH TO PASS" HIGH BEAM LEVER, IT BROUGHT THE HEADLIGHTS ON ALLOWING HER TO MAKE IT HOME. THE HEADLIGHTS WERE CHECKED BY THE FORD DEALER ON AUGUST 5, 2011. TESTS REVEALED NO CAUSE BUT THE MECHANIC SUSPECTED THE LIGHT CONTROL MODULE. HE ADVISED FURTHER DRIVING, WHICH I DID THAT SAME EVENING ONLY TO EXPERIENCE REPEATED HEADLIGHT FAILURE WHEN USING EITHER TURN SIGNAL OR ACTIVATING THE HIGH BEAMS. THEN I DISCOVERED A NUMBER OF INTERNET POSTINGS IN WHICH DRIVERS EXPERIENCED THE SAME PROBLEM WITH GRAND MARQUIS' OR FORD CROWN VICTORIAS MADE IN THE 2000'S. THEN I FOUND A WEBSITE WHICH STATED THAT THE ORIGINAL LIGHT CONTROL MODULE HAD A MAJOR PROBLEM INVOLVING A BAD CIRCUIT THAT IS THE DEFINITIVE CAUSE OF THE PROBLEM. THE LOCAL FORD DEALER ACKNOWLEDGED AWARENESS OF THE PROBLEM (EVEN CITING SEVERAL CROWN VICTORIA POLICE INTERCEPTORS THAT REQUIRED LCM REPLACEMENT), BUT BECAUSE FORD HAS NOT ISSUED A RECALL, THEY WANTED OVER $1,000 FOR DIAGNOSIS, PART, AND LABOR. A WEBSITE ALSO NOTED THAT FORD RECENTLY COMPLETELY REVISED THE LCM WITH AN INTERNAL REDESIGN BY FORD ENGINEERS SO THAT THE NEW LCMS WILL NEVER FAIL. THE WEBSITE ALSO NOTED THAT SOME DEALERS CONTINUE TO SELL THE OLD DEFECTIVE LCM WHICH WILL ONLY FAIL AGAIN. MY OPINION: BESIDES NOT WANTING TO PAY AN EXHORBITANT AMOUNT TO REPLACE ONE COMPONENT OF A VEHICLE'S LIGHT SYSTEM, IT APPEARS FORD IS FULLY AWARE OF A POTENTIALLY DEADLY DEFECT AFFECTING MANY THOUSANDS OF GRAND MARQUIS' AND CROWN VICTORIAS CURRENTLY IN USE, BUT HAS NOT ISSUED A RECALL. THIS POTENTIALLY DEADLY DEFECT MUST BE ADDRESSED! IT IS ENTIRELY POSSIBLE FATAL ACCIDENTS HAVE ALREADY OCCURRED BUT WERE MISATTRIBUTED.

BOTH HEADLIGHTS FAILED, IN BOTH DIM AND HIGH-BEAM POSITIONS. THEY WILL NOT COME ON IN EITHER THE AUTOMATIC OR MANUAL DASHBOARD SWITCH POSITIONS. (THE BULBS ARE STILL GOOD.) THE PARKING LIGHTS, TURN SIGNALS, TAIL LIGHTS, AND BRAKE LIGHTS CONTINUED TO FUNCTION. THIS HAPPENED AT NIGHT. IT SHOULD BE OBVIOUS THAT THIS FAILURE WILL *ALWAYS* OCCUR AT NIGHT, OR DURING STORMY WEATHER, THREATENING SAFETY, BECAUSE HEADLIGHTS ARE NOT NORMALLY USED DURING THE DAYTIME. LATER TESTING REVEALED THE PROBLEM TO BE INTERMITTENT. AT ONE POINT, THE AUTOMATIC DASHBOARD SWITCH POSITION WORKED FOR BOTH DIM AND HIGH-BEAMS, BUT THE MANUAL SWITCH POSITION DID NOT WORK. THE NEXT MORNING, BOTH THE AUTOMATIC AND MANUAL POSITIONS WORKED. WHEN THE PROBLEM FIRST OCCURRED, NEITHER POSITION WOULD WORK. THIS INTERMITTENT PROBLEM IS CONSISTENT WITH A LARGE NUMBER OF COMPLAINTS AND REPORTS FOR THE 2003-2005 MODEL YEARS, AND THE PROBLEM IS THE LIGHTING CONTROL MODULE. THIS MODULE IS SO UNRELIABLE THAT IT HAS BEEN NAMED THE "LIGHTS OUT MODULE" ON THE INTERNET.

THIS IS A *SAFETY* ISSUE. LIVES ARE AT STAKE. PLEASE FORCE A RECALL TO CORRECT THIS PROBLEM BEFORE INNOCENT PEOPLE ARE KILLED. ALTHOUGH THE PARKING LIGHTS AND TAIL LIGHTS CONTINUED TO WORK, SO OTHER DRIVERS CAN SEE THE CAR WITH THE FAILED HEADLIGHTS, THE DRIVER OF THE CAR WITH THE FAILED HEADLIGHTS *CANNOT* SEE WHERE HE IS GOING!!

Status: closed (inferred from source dates) · Exterior Lighting; Exterior Lighting:headlights

The Office of Defects Investigation (ODI) opened an investigation concerning the loss of headlights in model year (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles. The subject vehicles share the same architecture and major components.ODI has received 636 unique reports (for all submission dates) related to the alleged defect, with owners describing a loss of both low and/or high beam headlights occurring while driving.ODI identified 4 Vehicle Owner Questionnaire ( VOQ) reports alleging minor crash or loss of control incidents due to headlight failures.Drivers alleged running off of the road due to a lack of headlights and one driver reportedly struck a deer.No injuries were indicated in the VOQ crashes.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 4173 unique reports related to the alleged problem.There were a total of 11 crashes reported within that group as well as one injury that occurred when the vehicle struck an unseen object on the side of the road when the headlights failed. Ford also submitted 49,843 warranty claims related to headlight failures.Most reports indicate that the headlights failed without warning leaving the driver with no forward lighting, however some noted the headlights flickered or dimmed prior to turning off.Consumers also noted they were able to hold the flash to pass lever on the steering column mounted stalk to activate the high beams however this is only effective as long as the lever is physically actuated.On December 21st, 2015 Ford notified ODI that it would conduct a safety recall (15V-861) to remedy headlight failures on (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles.According to Ford, the headlights of the vehicle are controlled by the Lighting Control Module (LCM) located in the engine compartment of the vehicle.The LCM uses an internal relay, mounted to a circuit board, to control power to the headlights. The headlight relay is soldered to the circuit board at six different terminals. The original equipment LCMs were manufactured in a manner that resulted in the solder joints fatiguing and/or cracking as a result of repeated thermal cycling and/or vibration, a defect condition. The condition could be exacerbated by manufacturing quality issues such as an insufficient amount of solder, effecting the continuity between the circuit board and the relay terminal, and resulting in loss of headlights while driving.Other lighting functions are unaffected by this condition.The LCM manufacturing processes were revised to address the defect condition and Ford has been conducting a warranty extension program to cover defective LCMs since late 2013.Under the recall Ford will replace any remaining defective LCMs in recalled vehicles with remedy LCMs once they become available.See NHTSA recall 15V-861 for further details on the safety recall.The recall action initiated by Ford addresses the safety risks of concern to ODI.Accordingly, the investigation is closed.The ODI reports cited above can be reviewed at SaferCar.gov under the identification (ODI) numbers found in the attached list.

On July 7, 2014 the Office of Defects Investigation (ODI) opened a preliminary evaluation based on five complaints (VOQs) alleging incidents ofinterference between dislodged exhaust manifold heat shields and the lower steering shaft/knuckle, including one alleging the interference resulted in a crash on a highway entrance ramp. Since opening this investigation, ODI has received four additional owner complaints.One indicated that the shield was removed before binding could occur.The other three occurred at low speed and produced some momentary steering binding that was overcome by the driver when additional steering effort was applied.Once the shield was repaired or removed, the steering returned to normal.The single incident ODI identified as a possible crash (VOQ No. 10578715) related to this condition could not be verified and the description of the crash in the complaint was not supported by the police accident report.No additional crash allegations have been identified related to the alleged defect condition.Information provided by Ford in its September 10, 2014 response to ODI's information request letter identified 10 additional incidents resulting in a low rate of 1.6 incidents per 100,000 vehicles sold in vehicles ranging from 7 to 11 years in service.Six of these incidents were reported by a single source, a state police fleet that corrected the problems in March 2011 and has not reported any additional failures since.Ford also reported 5 warranty claims, but these incidents occurred at very low mileages and appeared to be caused by loose or missing heat shield attachment hardware rather than the corrosion condition that was the cause of the more recent incidents and the focus of this investigation.This investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.The following VOQs are associated with this investigation:10643753, 10615584, 10611362, 10610451, 10578715, 10479681, 10471833, 10317493.
