2004 MERCURY GRAND MARQUIS Complaints

THE HEADLIGHTS FAILED DURING OPERATION OF THE VEHICLE WHILE IN LIGHT RAIN AT NIGHT IN TOWN. I DID NOT NOTICE THE LIGHTS FAILED, ON COMING TRAFFIC FLASHED THEIR LIGHTS TO TELL ME MY LIGHTS WERE OFF. PULLING OVER TO THE CURB I WIGGLED THE CABLING UNDER THE DASH AND THE LIGHTS CAME ON, I THEN PROCEEDED TO MOVE AGAIN AND THE LIGHT WENT OFF. AFTER A FEW ATTEMPTS OF WIGGLING THE CABLING NEAR THE LEM MODULE THE LIGHTS STAYED ON ENOUGH TO RETURN TO MY HOME. THIS HAS BEEN AN ON GOING SITUATION WITH THE LIGHTS, AND I HAVE BEEN ON THE INTERNET TO TROUBLESHOOT THIS FAULT IN THE FORD MOTOR VEHICLES. THAT THIS PROBLEM HAS BEEN REPORTED WITH OUT A RECALL IS APPALLING. THE LOCATION OF THE FAILED UNIT MOST LIKELY IS THE REASON FOR SERVICE MECHANIC ESTIMATES OF $700 TO $1500 TO REPLACE THIS PART. ONE ONLY HAS TO GO ON THE INTERNET AND WRITE THE 2004 LIGHTING PROBLEM AND SEE THE LEM MODULE HAS A UN-GOING PRODUCT FAILURE. *TR

TL* THE CONTACT OWNS A 2004 MERCURY GRAND MARQUIS. THE CONTACT STATED THAT THE HEADLIGHTS SHUT OFF WITHOUT WARNING. THE LIGHTS WOULD CONTINUOUSLY FLICKER ON AND OFF. IN 2006 AND 2009, THE DEALER REPLACED THE LIGHTING CONTROL MODULE HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT DID NOT OFFER ANY ASSISTANCE. THE CURRENT MILEAGE WAS 121,000 AND THE FAILURE MILEAGES WAS 60,000. UPDATED 01/05/12*LJ UPDATED 01/09/12

TL* THE CONTACT OWNS A 2004 MERCURY GRAND MARQUIS. WHILE DRIVING APPROXIMATELY 65 MPH, THE VEHICLES SPEED INCREASED. WHEN THE BRAKE PEDAL WAS ENGAGED, THE VEHICLE BEGAN TO REDUCE SPEED. THE CONTACT MANEUVERED ONTO THE EMERGENCY LANE AND TURNED THE VEHICLE OFF. AFTER RESTARTING THE VEHICLE, IT BEGAN TO FUNCTION NORMALLY. THE FAILURE OCCURRED THREE TIMES. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR DIAGNOSTIC TESTING AND THE THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 50,000. THE VIN WAS UNAVAILABLE.

"CHECK AIR SUSPENSION" LIGHT CAME ON. VEHICLE BOTTOMED OUT CAUSING VERY POOR HANDLING AND CONTROL. REPAIR SHOWED FAILURE OF AIR COMPRESSOR PUMP, PART NUMBER 8W1Z5319A, A PART COMMON TO FORD MOTOR VEHICLES WITH AIR SUSPENSION. THE REPLACEMENT PUMP HAS A MRP OF $410.00 AND $238.00 LABOR. THE VEHICLE IS ONLY DRIVEN ON PAVED ROADS AND HAS NEVER BEEN DAMAGED BY POOR ROAD CONDITIONS.

I HAD WHAT SEEMS TO BE A SIMPLE COOLANT LEAK BUT IT TURNED OUT TO BE THE PLASTIC INTAKE MANIFOLD CRACKED. PUTTING A PLASTIC PART ON TOP OF A MOTOR SEEMS TO ME A FAILURE OF ENGINEERING ON THE PART OF FORD. I DID NOT RECEIVE ANY CALL BACK FOR THIS PART. I DID SOME SEARCHING ON THE WEB AND FOUND THAT MANY FORD OWNERS HAD THE SAME PROBLEM. I PLAN TO CALL FORD COMPANY ON MONDAY. DO YOU HAVE ANY INFO FOR ME ON THIS SUBJECT. THANK YOU. *TR

TL* THE CONTACT OWNS A 2004 MERCURY GRAND MARQUIS. THE CONTACT WAS DRIVING 45 WHEN THE HEADLIGHTS ILLUMINATED ON AND OFF INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THEY REPLACED THE SWITCHES FOR THE HEADLIGHTS. THE MANUFACTURER WAS NOT CONTACTED AND THE FAILURE PERSISTED. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 60,000 AND THE CURRENT MILEAGE WAS 80,000.

MY MERCURY MARQUIS IS UNSAFE! BOTH OF MY NIGHT-TIME HEADLIGHTS WENT OUT AT THE SAME TIME. ALL OTHER LIGHTS WORK FINE INSIDE AND OUT. THE HEAD-LIGHTS NOW ONLY WORK IF I HOLD THE HIGH-BEAM BAR, HOWEVER, THEY DO NOT WORK IF I LET GO OF THE CONTROL BAR. I DRIVE MY VEHICLE VERY LITTLE, AND MOSTLY DURING THE DAY; HOWEVER, I DO TAKE 70 MPH INTERSTATE HIGHWAY TRIPS RETURNING AT NIGHT. THERE IS NO FUSE FOR THE HEAD LIGHTS OR THE LIGHT CONTROL MODULE IN EITHER THE FUSE BOX ABOVE THE BRAKE PEDAL, OR UNDER THE HOOD. FURTHER INVESTIGATION REVEALS THAT THE HEAD LIGHT FUSE IS INSIDE THE LIGHT CONTROL MODULE WHICH IS LOCATED UNDER THE DASH ABOVE THE GAS-PEDAL. ALSO, I'VE LEARNED THAT EVEN WHEN THIS LCM UNIT IS REPLACE, THAT A NEW LCM UNIT CAN BE DEFECTIVE ALSO. COMMON SENSE DICTATES THAT SOMETHING ELECTRICAL IS CAUSING THE FUSE TO BLOW IN THE UNIT. I BELIEVE THIS INDICATES A LOOMING FIRE HAZARD ABOUT TO HAPPEN. OVERHEATING THE ELECTRICAL SYSTEM FROM WHERE? IF I WOULD ELECT TO HAVE THE LCM UNIT MODIFIED WITH A LARGER INTERIOR FUSE, I FEAR THIS IS NOT A SOLUTION EITHER. FORD NEEDS TO FIND THE SOURCE OF THE PROBLEM THAT IS BLOWING THIS FUSE EVEN IN THE NEW UNITS. THE INSTALLATION AT THE DEALERSHIP IS $700.00 OR ABOVE. THE MARKET PRICE OF THE LCM UNIT IS $90. FORDS NEEDS TO RECALL AND REPLACE THIS LCM UNIT FOR AN INDEFINITE PERIOD; HOWEVER, SINCE THEY ARE MAKING A BUNCH OF MONEY REPLACING THEM, AND NO ONE HAS GOTTEN KILLED YET, WILL THEY? I FEAR REPLACING THE UNIT THIS WEEK, AN THE NEW ONE FAILING AND ME, SUDDENLY WITH NO HEADLIGHTS POSSIBLY RUNNING OVER A PEDESTRIAN, OR CRASHING ON THE INTERSTATE AND ME OR SOMEONE DYING. THIS PROBLEM MAKES MY MERCURY ABSOLUTELY UNSAFE !!! I WANT AN INDEFINITE RECALL OF THIS UNIT, AND FOR FORD TO FIND AND REPAIR THE CAUSE OF THE UNIT FAILING. *TR
