I OWN A 2005 MERCURY GRAND MARQUIS GS ORIGINAL OWNER WITH 37,700 MILES ON THE ODOMETER. A WEEK AGO MY DRIVERS SIDE AIR BAG WARNING LIGHT CAME ON WHEN I STARTED THE CAR AND IT REMAINS ON WHILE DRIVING. AFTER CHECKING WITH ONE OF MY MECHANICS, I WAS TOLD THE AIR BAG WILL NOT DEPLOY IF I AM IN A FRONT END COLLISION. I THINK THIS IS THE SAME PROBLEM OTHERS 2005 MERCURY GRAND MARQUIS' HAVE HAD WITH THE DRIVERS SIDE SEAT BELT PRE-TENSIONER, AND THINK IT WILL NEEDS TO BE REPLACED. I WILL BE CONTACTING MY LINCOLN(FORMERLY MERCURY) DEALERSHIP ON BELL ROAD IN PHOENIX, AZ, TO TAKE IT IN FOR REPAIRS. WHILE I HAVE NEVER HAD A ACCIDENT WITH THE CAR, I CAN'T TAKE THE CHANCE THAT ME OR MY WIFE WILL NOT HAVE THE AIR BAG DEPLOY IN THE CASE OF A FRONT END COLLISION. I PURCHASED THE AUTO IN DECEMBER, 2004, AND AM THE ORIGINAL OWNER WITH ONLY 37,700 MILES ON THE CAR. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

HEAD LIGHTS WERE COMING ON AND GOING OFF ON THEIR OWN, NOW WILL NOT COME ON. FAULTY LIGHT CONTROL MODULE! *TR
PASSENGER AIR BAG LIGHT CAME ON WILL NOT GO OUT. STAYS ON WITH PERSON IN PASSENGER SEAT WITH SEAT BELT ON. *TR
WHILE DRIVING AT NIGHT, THE HEADLIGHTS SUDDENLY GO OUT. THIS IS VERY DANGEROUS, REGARDLESS OF EITHER DRIVING ON THE HIGHWAY OR IN THE CITY (ESPECIALLY WITH PEDESTRIANS). THEY TEND TO STAY OUT FOR 10-15 MIN BEFORE THEY START WORKING AGAIN. WHILE THEY ARE OUT, THE BRAKE LIGHTS GO OUT AT THE SAME TIME, MAKING IT EVEN MORE SCARIER, CANT SEE TO DRIVE, AND THE CAR BEHIND ME CANT SEE ME SLOWING DOWN OR STOPPING, WHICH INCREASES THE CHANCES FOR AN ACCIDENT. NEEDS TO BE RECALLED ASAP. IT APPEARS THAT IT IS THE LIGHTING CONTROL MODULE IS FAULTY AND THE PART ITSELF IS QUITE COSTLY STARTING AT $300 - $500 FOR THE PART ITSELF OR $800 INSTALLED. *TR
I OWN A 2005 MERCURY GRAND MARQUIS. THE AIR BAG WARNING LIGHT ILLUMINATED ONCE THE ENGINE WAS STARTED AND REMAINED ON. THE VEHICLE WAS TAKEN TO THE LOCAL FORD DEALER SERVICE DEPARTMENT FOR DIAGNOSIS AND I WAS INFORMED THAT THE DRIVER'S SIDE SEATBELT PRETENSIONER WOULD NEED TO BE REPLACED AT A COST OF $501 IN ADDITION TO THE $103 CHARGED FOR DIAGNOSIS. THE VEHICLE HAS NOT YET BEEN REPAIRED. I WILL INFORM THE MANUFACTURER. I OBSERVE FROM OTHER WEBSITES/REPORTS WHAT I BELIEVE MAY BE A PATTERN OF PREMATURE FAILURE OF GRAND MARQUIS SEATBELT PRETENSIONERS ESPECIALLY IN THE 2005 MODEL YEAR. THE FAILURE MILEAGE WAS 127,084 AND THE CURRENT MILEAGE WAS 127,201. *TR

HEAD LAMPS GO OUT OR FAIL TO COME ON. *TR
I WAS RETURNING HOME WITH MY WIFE FROM A TRIP TO CHARLESTON, SC, AT ABOUT 10:00 PM, DRIVING AT 60 MPH, WHEN MY HEADLIGHTS SUDDENLY SHUT OFF. THAT HAPPENS IN THE VICINITY OF AWENDAW AND THERE ARE NO STREET LIGHTS IN THE AREA. BOTH MY WIFE AND I SCREAMED IN PANIC WHILE I WAS TRYING TO SLOW DOWN THE CAR AND STAYING IN MY LANE ON THE HIGHWAY. I WAS THANKFUL THAT THE TURN SIGNALS, MARKER LIGHTS AND BRAKE LIGHTS STILL WORKED, SO ANY OTHER CARS WOULD BE ABLE TO SEE ME. WHEN I FINALLY PULLED UP THE SIDE OF THE ROAD WITHOUT ANY MISHAPS, I INSPECTED THE CAR AND FOUND OUT THAT ALL THE FUSES WERE GOOD. I THEN RESTARTED THE CAR AND STILL DID NOT GET MY HEADLIGHTS TO COME ON. I PLAYED WITH THE TURN SIGNAL/ LOW BEAM/HIGH BEAM LEVER AND GOT THE FLASHING HIGH BEAM POSITION TO WORK, SO I DROVE HOME TO MYRTLE BEACH HOLDING THE FLASHING HIGH BEAM LEVER UP TO LIGHT MY WAY. OTHERWISE, I WOULD HAVE TO HIRE A TAXI, SPEND THE NIGHT IN THE NEAREST HOTEL TO WAIT FOR DAYLIGHT TO RESUME MY TRIP HOME. APPARENTLY, THE PROBLEM WITH THE HEADLIGHTS SHUTTING OFF WITHOUT WARNING WHILE DRIVING AT NIGHT COMES FROM THE LIGHTING CONTROL MODULE INSTALLED THE 2005 MERCURY GRAND MARQUIS THAT MALFUNCTIONS WHEN THE CARS REACHED AN AVERAGE MILEAGE OF 69,000 MILES (SOME AS EARLY AS 30,000 MILES, UP TO 114,000 MILES DOCUMENTED). *TR
HEADLIGHTS GO OFF, TAIL LIGHTS AND RUNNING LIGHTS STAY ON. AFTER SLAMMING DOOR OR SLAMMING HOOD LIGHTS WOULD SOMETIMES COME BACK ON AGAIN FOR A WHILE, THEN GO ON AND OFF AT RANDOM WITH LIGHT SWITCH TURNED TO "ON". CHECKED ALL FUSES AND RELAYS I COULD ACCESS AND ALL WERE OK. HAS ACTED THIS WAS FOR THREE WEEKS NOW. IT'S DANGEROUS TO DRIVE AT NIGHT. *TR
STEERING COL. SEPARATION. IT IS THE SAME SEPARATION PROBLEM THE POLICE CARS ARE HAVING. I WANTED YOU TO KNOW THIS HAPPENED BECAUSE FORD HAS BEEN SAYING IT HASN'T HAPPENED IN OTHER CARS BESIDES THE POLICE CARS WHEN IT HAS. *TR

THIS IS AN ONGOING PROBLEM -- THIS WINTER THE HEADLIGHTS STARTED TURNING OFF ON THEIR OWN, FORCING YOU TO HOLD THE BRIGHTS IN POSITION SO AS TO CONTINUE DRIVING AT NIGHT. AT FIRST THEY CAME BACK ON. NOW THEY COME BACK ON RARELY. THE FIRST TIME THE LIGHTS ARE PUT ON AFTER THE CAR HAS BEEN PARKED FOR A WHILE THEY MAY STAY ON (BETTER THAN 50/50 CHANCE). BUT AFTER TURNING CAR OFF DURING NIGHT AND RESTARTING, THE LIGHTS ALWAYS FAIL A FEW MINUTES OR LESS INTO YOUR DRIVE. WHY HASN'T FORD BEEN FORCED TO RECALL THIS? *TR
TL* THE CONTACT OWNS A 2005 MERCURY GRAND MARQUIS. THE CONTACT STATED THAT THE HEADLIGHTS WOULD FAIL INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER BUT WAS NOT DIAGNOSED.

THE CURRENT MILEAGE WAS APPROXIMATELY 104,000. *TR...UPDATED 04/25/13 *BF THE CONSUMER WAS ADVISED THAT THERE IS A REPLACEMENT PART BUT IT WILL ALSO FAIL IN DUE TIME. UPDATED 05/17/2013*JS
WE HAD JUST LEFT A FUNERAL HOME AND DRIVING BACK HOME ON A 4 LANE ROAD. WE TURNED TO AVOID GETTING ON THE HIGHWAY IMMEDIATELY AND DECIDED TO TAKE ANOTHER ROUTE. AS WE WERE HEADING UP THIS 2 LANE ROAD THAT WAS DARK ALL OF A SUDDEN OUR HEADLIGHTS AND INSTRUMENT PANEL LIGHTS WENT OUT AND CARS COMING AT US WERE FLASHING THEIR LIGHTS. I SLOWED DOWN AND WAS ABLE TO PULL OVER TO A SIDE STREET. SAT THERE TRYING TO DETERMINE WHY THE LIGHTS WERE OUT. TURNED THE SWITCH FROM THE ON POSITION TO THE AUTOMATIC POSITION AND THE LIGHTS CAME BACK ON. WE DROVE ALL THE WAY HOME ON BACK ROADS TO AVOID GETTING ON THE INTERSTATE, NOT KNOWING IF THE LIGHTS WOULD GO OUT OR NOT. READ THE MANUAL TO SEE IF WE HAD MISSED ANYTHING AND THEN GOT ON THE INTERNET AND SAW THE HUNDREDS OF PEOPLE HAVING THE SAME THING HAPPEN TO THEM. I WILL CONTACT THE DEALER AND SEE ABOUT FIXING IT BUT FROM WHAT I HAVE READ, THE LIGHT CONTROL MODULE IS BAD AND SO ARE THE REPLACEMENTS. I AM HOPEFUL THAT THERE IS A NEWER IMPROVED MODEL THAT IS NOW BEING USED. THANK GOD WE WERE NOT ON THE HIGHWAY OR WE COULD HAVE BEEN KILLED. THIS IS A SERIOUS PROBLEM. *TR
WHILE DRIVING AT NIGHT, MY HEADLIGHTS WITHOUT WARNING, EXTINGUISHED. I TURNED THE 'HIGH BEAMS' ON AND THEY ALSO FAILED TO LIGHT. I STOPPED AND AFTER A FEW MINUTES, THE LIGHTS CAME BACK ON. I SEARCHED THE INTERNET AND FOUND THAT MANY FORD CROWN VICTORIA / MERCURY GRAND MARQUIS (MULTIPLE MODEL YEAR) AUTOMOBILES ARE SUFFERING FROM THE SAME PROBLEM. IT IS APPARENTLY A FAILURE IN THE 'LIGHTING CONTROL MODULE' (LCM). THERE ARE MANY WEB SITES THAT OFFER RE-MANUFACTURED LCM'S BUT I QUESTION WHY THIS IS NOT A SAFETY RECALL? I THINK THAT LOSING YOUR HEADLIGHTS WHILE DRIVING AT NIGHT WOULD SOMEHOW QUALIFY AS A SAFETY HAZARD AND THIS SHOULD BE THE MANUFACTURER'S RESPONSIBILITY TO FIX THIS PROBLEM. *TR
TL* THE CONTACT OWNS A 2005 MERCURY GRAND MARQUIS. THE CONTACT STATED THAT THE HEADLIGHTS FAILED WITHOUT WARNING WHILE DRIVING AT NIGHT.

WHILE DRIVING DOWN THE INTERSTATE MY HEADLIGHTS CUT OFF. MY PARKING LIGHTS REMAINED ON. THE ONLY WAY TO SEE THE ROAD WAS TO HOLD THE HIGH BEAM SWITCH. THIS IS THE FOURTH TIME THAT THIS HAS HAPPENED IN THE LAST 2 WEEKS. THERE IS NO PATTERN OF OCCURRENCE. I INVESTIGATED ON THE INTERNET AND THERE ARE MULTIPLE REPORTS OF THIS HAPPENING THROUGHOUT THE COUNTRY. THE HEADLIGHT MODULE SEEMS TO BE THE PROBLEM. *TR

THIS IS A VERY DANGEROUS PROBLEM. THE LIGHTS GO OUT ON THE MERCURY MARQUIS. IT IS INTERMITTENT. SOMETIMES, THEY WILL GO BACK ON. I HAVE TO HOLD THE HIGH BEAM TO GET HOME. EXTREMELY DANGEROUS! THEY SHOULD HAVE A RECALL AND STOP TRYING TO SLIDE OVER THE ISSUE. *TR

AS I WAS DRIVING THE HEADLIGHTS WENT COMPLETELY OFF, SWITCHED TO MANUAL, WORKED FOR A FEW MINUTES, THEN WENT OFF AGAIN. TRIED TURNING CAR OFF AND BACK ON, NO LIGHTS, HAD TO HOLD DIMMER SWITCH FORWARD TO GET LIGHTS. THIS HAS HAPPENED NUMEROUS TIMES SINCE THE FIRST ONE. NOW NOT EVEN HOLDING THE DIMMER SWITCH FORWARD ALWAYS WORKS. TODAY WE WERE STOPPED BECAUSE TAIL LIGHTS WERE OUT (DRIVER WAS HOLDING DIMMER SWITCH FORWARD). TAIL LIGHTS ALSO FLICKER AT TIMES WHEN HEADLIGHT GOES OUT AND CONTROL PANEL FLICKERS TOO. WE HAVE GONE TO LOCAL INDEPENDENT REPAIR SERVICE AND ARE HAVING DIFFICULTY GETTING CONTROL MODULE DUE TO LARGE BACK ORDER. SO WHAT ARE WE TO DO IN THE MEANTIME? THIS IS EXTREMELY DANGEROUS TO THOSE IN THE CAR AND OTHERS ON THE ROAD. I UNDERSTAND RECALLS ARE WHEN THERE IS A DANGEROUS SITUATION, AND THIS DEFINITELY QUALIFIES! SO WE NOW OWN A CAR THAT WE CAN'T DRIVE WHENEVER HEADLIGHTS ARE NEEDED, WHICH IS VERY LIMITING. SO FAR I HAVE NOT BEEN ABLE TO GET HOLD OF FORD DIRECTLY TO COMPLAIN ABOUT THIS. WE ARE NOT THE ORIGINAL OWNERS, BUT THAT SHOULD NOT MATTER ON SUCH A SERIOUS ISSUE! THIS COMPLAINT IS ABOUT A 2005 GRAND MARQUIS. *TR

HEADLIGHTS GO OUT INTERMITTENTLY. *TR
WHILE DRIVING ON A DARK COUNTY ROAD ALL HEADLIGHTS WENT OFF. HAD TO DRIVE NEARLY A MILE WITH NO HEAD LIGHTS OR STREET LIGHTS BEFORE I REACHED A PLACE I COULD PULL OVER. AFTER CAR SAT FOR SEVERAL MINUTES LIGHTS WORKED AGAIN. EXTREMELY FRIGHTENING AND DANGEROUS! I CAN NOT BELIEVE THIS IS A KNOWN ISSUE AND NO RECALL HAS BEEN ISSUED! *TR
THIS IS THE SECOND TIME THE LCM HAS, WITHOUT WARNING, FAILED. THE FIRST TIME, WHILE DRIVING ALONG US1 AFTER DARK, ALL LIGHTS - HEADLIGHTS, TAIL LIGHTS, AND DASHBOARD LIGHT - WENT OFF!! THERE WERE NO STREET LIGHTS AND CARS COULD NOT SEE US FROM BEHIND AND WE COULD NOT SEE WHERE WE WERE GOING! WE WERE TERRIFIED. OUR LIVES WERE AT STAKE AS WE ANXIOUSLY AND EXTREMELY SLOWLY MADE OUR WAY HOME. THE REPAIR WAS OUTRAGEOUSLY COSTLY. AND, OF COURSE, WE WERE RESTRICTED TO DRIVING ONLY IN SUNNY DAYLIGHT HOURS AS LIGHTS ARE REQUIRED WHEN RAINING. NOW, THIS HAS HAPPENED AGAIN. THE CAR HAS BEEN TAKEN TO THE LOCAL FORD DEALER. HOWEVER, ALTHOUGH THE PART HAS BEEN ORDERED FOR OVER 10 DAYS, THERE IS NO WORD AS TO WHEN IT WILL BE AVAILABLE AND WE ARE ABOUT TO TAKE A FOUR-DAY TRIP! WE HAVE CONTACTED THE FORD MOTOR CO. ABOUT THIS PROBLEM, BOTH BY PHONE AND BY EMAIL, AND ALL THEY CAN SAY IS THAT IT NEEDS TO BE FIXED. EXCUSE ME! THIS IS A LIFE AND DEATH ISSUE!!! WE COULD HAVE BEEN KILLED ON THE HIGHWAY DUE TO A FAULTY LCM! IN ALL OUR YEARS WE HAVE NEVER HAD THIS HAPPEN WITH ANY OTHER CAR. WE HAVE READ IN SEVERAL BLOGS THAT THERE ARE DEFECTIVE MODULES BEING USED - YES, FROM FORD MOTOR CO.! DOES THERE NEED TO BE A HIGHWAY DEATH DUE TO THIS DEFECT BEFORE FORD WILL ACKNOWLEDGE THIS PROBLEM AND REPLACE THIS PART AT THEIR EXPENSE?? *TR UPDATED IVOQ 12/19/12

DRIVING AT NIGHT WHEN HEAD LIGHTS WENT OUT ALL OTHER LIGHTS WERE ON. WE COULD KEEP THE HIGH BEAMS ON BY HOLDING DIMMER SWITCH UP. LIGHTS WOULD COME ON AND THEM GO OFF AGAIN.
TL* THE CONTACT OWNS 2005 MERCURY GRAND MARQUIS. THE CONTACT STATED THAT WHILE PARKED THE HEADLIGHTS FAILED TO ILLUMINATE.

WHILE DRIVING AFTER DARK THE HEADLIGHTS AND DASHBOARD LIGHTS WENT DARK. WHILE ATTEMPTING TO RESTORE THE LIGHTS, THEY CAME BACK ON. WITHIN TEN MILES, THIS EVENT OCCURRED TWO MORE TIMES. I WENT TO MY LOCAL MERCURY DEALER WHO TOLD ME THAT THE MODULE THAT CONTROLLED THE HEADLIGHTS AND DASHBOARD LIGHTS WAS NOT AVAILABLE. HE ALSO TOLD ME THAT HIS ORDERING SYSTEM ALSO SHOWED HIM THAT THERE WERE ALMOST 600 OF THESE PARTS WERE ON BACK-ORDER. HE ALSO TOLD ME THAT ONE OF THE COMPONENTS OF THE MODULE WAS UNAVAILABLE AND THAT THERE WAS NO ANTICIPATED DATE WHEN THE MODULE MIGHT BE AVAILABLE. HE ALSO TOLD ME THAT 2005 WAS THE ONLY MODEL YEAR THAT THIS PART WOULD FIT AND THAT THE 2004 OR 2006 SIMILAR PARTS WOULD NOT WORK IN THE 2005 MODEL YEAR. HE ALSO TOLD ME THAT IF THE PART WERE AVAILABLE THAT IT WOULD COST ALMOST $600 DOLLARS NOT INSTALLED. THIS PART ALSO FITS THE 2005 FORD CROWN VICTORIA BUT NO OTHER MAKES OR MODELS. THIS LEADS ME TO BELIEVE THAT FORD RE-ENGINEERED THIS MODEL FOR THE 2005 MODEL AND DISCOVERED THAT IT WAS A FAULTY DESIGN AND REDESIGNED IT FOR THE 2006 MODEL AND FAILED TO REPORT THE PROBLEM TO ANYONE. THEY HAVE USED UP ALL OF WHATEVER INVENTORY OF THESE PARTS THEY EVER MANUFACTURED AND APPEAR TO HAVE NO PLANS TO MAKE ANY MORE. I HAVE SHOPPED MOST OF FLORIDA'S JUNK YARDS AND HAVE NOT BEEN ABLE TO LOCATE ANY 2005 MERCURY OR FORD CARS FROM WHICH TO OBTAIN A USED PART. BEFORE DAYLIGHT THIS MORNING WHILE DRIVING MY WIFE TO THE DOCTOR, THE HEADLIGHTS AND DASH LIGHTS WENT OUT ON

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
