2005 MERCURY GRAND MARQUIS Complaints

I WAS DRIVING DOWN THE HIGHWAY WHEN MY LIGHTS SUDDENLY WENT OUT NOT COMING BACK ON. *TR

AT ANY GIVEN TIME THE LIGHTS JUST GO OUT AND I CAN ONLY SEE BY MANUALLY USING THE HIGH BEAM LIGHTS. THE LIGHTS WILL COME ON FOR A FEW MOMENTS THEN OUT THEY GO AGAIN. YOU CAN HEAR A CLICKING SOUND WHEN IT IS GOES OUT AND BACK ON. THIS IS EXTREMELY DANGEROUS ESPECIALLY SINCE I HAVE 3 CHILDREN IN MY VEHICLE AND ANY GIVEN TIME. *TR

THE HEADLIGHTS ON THE VEHICLE WENT OUT WHILE DRIVING ON THE HIGHWAY. PARKING LIGHTS STAYED ON AND FLASHERS WORKED ALLOWING TO GET THE CAR TO THE BREAK DOWN LINE. THIS HAS HAPPEN ABOUT 8-10 TIMES SINCE THE FIRST. IN CHECKING FOR A FIX, I FOUND THERE ARE A NUMBER OF COMPANIES OFFERING A REPAIR SOLUTION AND THIS LOOKS LIKE A COMMON AND DANGEROUS PROBLEM THAT OCCURS OFTEN. I NOTICED THIS HAS BEEN INVESTIGATED BEFORE BUT NOTHING DONE. HAVING YOUR HEADLIGHTS GO OUT SEEMS DANGEROUS ENOUGH TO ME. THE REPAIR PART TO DO IT YOURSELF IS SOLD FOR ABOUT $10. $125 + TO PURCHASE A REPAIRED LIGHTING CONTROL MODULE. MY FORD DEALER WILL REPLACE THE LCM FOR $650. *TR

WHILE DRIVING WITH HEADLIGHTS ON AT NIGHT THE HEADLIGHTS TURN OFF. AFTER STOPPING AND TURNING CAR OFF AND RESTARTING ENGINE THE HEADLIGHTS EVENTUALLY START WORKING AGAIN. HAPPENED MULTIPLE TIMES THE SAME NIGHT. *TR

THE LOW BEAM HEADLIGHTS FAILED WHILE DRIVING AT VARIOUS SPEEDS WITHOUT WARNING. I WAS FORCED TO DRIVE WITH THE HIGH BEAMS ILLUMINATED. THIS HAPPENS VERY FREQUENTLY. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. I CALLED THE DEALER. THEY SAID IT WAS NOT COVERED UNDER WARRANTY. HE SAID THE PART WOULD BE ABOUT $600, AND WITH LABOR ALL COST WOULD RUN ABOUT $800!THE VEHICLE WAS NOT REPAIRED THE CURRENT MILEAGE WAS 71,100. REMANUFACTURED LCM IS ABOUT $300 OR NEW ABOUT $500 FROM AN INDEPENDENT AUTO PARTS STORE. *TR

MY WIFE DROVE THE CAR A FEW MILES, AFTER DARK, AT NIGHT. THE HEADLIGHTS WERE FUNCTIONING FINE. THEY MADE A BRIEF STOP AND WHEN THEY DROVE THE CAR OFF AND OUT OF THE LIT PARKING LOT, THEY DISCOVERED THAT THE HEADLIGHTS WOULD NOT COME ON IN AUTOMATIC MODE OR MANUAL MODE. THE PARK LIGHTS WORKED AND ALSO THE DASH LIGHTS WORKED. IT WAS NOT TILL THEY RAN OUT OF STREET LIGHTS BEFORE THEY DISCOVERED THEY HAD A PROBLEM. I GOT ONLINE AND DISCOVERED THAT THIS IS A COMMON PROBLEM WITH FORD PRODUCTS OF THAT MODEL. IT IS A POOR DESIGN AND IF THE HEADLIGHTS GO OFF AT HIGHWAY SPEEDS, IT COULD BE DANGEROUS. THE PART THAT USUALLY FAILS IS A DEALER ITEM THAT LIST FOR OVER $500.00 . FORD HAS UPGRADED THE NEW PART, SO THEY KNOW THAT THERE IS A PROBLEM. *TR
