Open the full vehicle complaint log (all categories)?yrs.ago While backing out of parking space at Calaveras Lumber, after shifting into reverse, & removing my foot from the brake; the engine appeared to receive a huge burst of fuel which shot me backward like a rocket slamming my vehicle into and wedging it under the frame of a pickup truck parked in the same lot. I am glad I was parked and had my foot on the brake prior to this unit or system malfunction otherwise the injuries could easily have been fatal on the highway. I think this defect may be a contributing factor to the car dying recently while on my way to a Wedding Reception in Roseville, which left me stranded after dark for 41/2hrs and 71/2hrs. 2days later. I have not been able to start vehicle since and mechanics unable to diagnose why the engine is fuel starved when system parts tested appear to be in good working order. Something seems to be shutting off power or preventing power to the fuel pump and it is not the inertia switch, relays, fuses etc.. Components have been previously inspected by numerous others including dealer. No Recognizable Alert/Warning Prior to Incidents!
TL* THE CONTACT OWNS A 2002 MERCURY GRAND MARQUIS. THE CONTACT STATED THAT THE HAZARD LIGHTS, DAYTIME RUNNING LAMPS, LOW BEAM, AND HIGH BEAM HEADLIGHTS FAILED TO ILLUMINATE. THE FAILURE PROGRESSED WITHOUT WARNING. TWO DEALERS (POMPANO FORD LINCOLN, 2741 N FEDERAL HWY, POMPANO BEACH, FL 33064, (888) 718-9266 AND SCHUMACHER LINCOLN OF DELRAY, 2102 S FEDERAL HWY, DELRAY BEACH, FL 33483, (561) 454-1800) WERE CONTACTED, BUT THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED. THERE WERE FIVE TSBS FOR THE EXTERIOR LIGHTING, BUT NO RECALL WAS ISSUED. THE APPROXIMATE FAILURE MILEAGE WAS 72,234.
AFTER DRIVING TO MALL MY DAUGHTER REALIZED THAT MY HEAD LIGHTS WERE NOT ON. CHECKED ALL FUSE (UNDER DASH AND UNDER HOOD). NONE WERE BLOWN. REALIZED THAT HAD NO DOME LIGHT BUT DID HAVE MAP/READING LIGHTS. NO TAIL LIGHTS OR BRAKE LIGHTS EXCEPT THIRD BRAKE LIGHTS. HAD BRIGHTS IF I HELD HIGH BEAM LEVER. HAD CAR TOWED TO SHOP. WAS TOLD THAT IT WAS THE LIGHT CONTROL MODULE (LCM). WAS TOLD THAT FORD HAD AND EXTENDED WARRANTY ON THIS PART. TOOK IT TO FORD DEALER. THEY SAID THAT IT WAS ONLY FOR THE 2003-2005 MODELS AND THAT MY CAR WAS NOT COVERED. I THINK THEY SHOULD EXTEND THIS WARRANTY TO THE THE 2002 MODELS SEEING THAT THIS IS A COMMON PROBLEM WITH EARLIER MODELS AND NOT JUST THE 2003-2005 MODELS. IT IS PROBABLY THE SAME PART.
DURING HEIGHT OF THE RUSH HOUR AT 4:00 PM I WAS TRAVELING ON NJ TURNPIKE AT 65 MPH IN THE MIDDLE LANE, STARTED TO HEAR A CLICKING SOUND. ALL OF A SUDDEN THE CAR'S ENGINE STOPPED, HAD NO POWER STEERING AND THE ENTIRE ELECTRICAL SYSTEM FAILED, (THE CAR'S BATTERY WAS REPLACED IN 12/2010) . DIRECTIONAL SIGNALS, AND EMERGENCY FLASHER DID NOT WORK, NOR COULD I LOWER THE WINDOWS. I WAS ABLE TO COAST TO THE SHOULDER OF THE ROAD WHEN A SLOW MOVING TRUCK WAS COMING UP ON THE RIGHT SIDE. NO CLICKING SOUND WAS HEARD TRYING TO RESTART THE CAR. *TR
WHILE COMING OFF THE HIGHWAY AT 55 MPH, THE PLASTIC PLASTIC COVER WHICH COVERED THE WIRES FELL DOWN DUE TO PIN FALLING OUT. CONTACT IS STILL DRIVING THE CAR. CAR IS REGULARLY SERVICED. CONTACT KEEPS SERVICE RECORDS. *AK WHEN THE COVER FELL OF IT MADE IT DIFFICULT FOR THE CONSUMER TO HIT THE BRAKE PEDAL. *NM
SLIGHT WHITE SMOKE APPEARING THROUGH VENTS IN AUTO. THEN WHEN WE PARKED IT EXTREME SMOKE CAME INTO VENTS FILLING PASSANGER COMPARTMENT. ALSO EXTREME WHITE SMOKE MIXED WITH BLACK CAME THROUGH VENTS BETWEEN HOOD AND WINDSHIELD. I OPENED HOOD AND IT WAS APPARENTLY BETWEEN FIREWALL & DASH. HAD TERRIBLE SMELL LIKE ROTTED TUNA. WIFE STILL HAVING BREATING PROBLEMS FROM INHALATION. HAD CAR TOWED TO DEALERSHIP.*AK
DT*: THE CONTACT STATED THE VEHICLE DID NOT ALWAYS START. WHEN IT DID START THE ENGINE STALLED WHILE IDLING. TO ALLEVIATE STALLING THE ACCELERATOR PEDAL MUST BE PUMPED HARD WHILE STARTING THE VEHICLE. THE VEHICLE HAS BEEN TO THE DEALERSHIP MULTIPLE TIMES AND THEY WERE UNABLE TO DUPLICATE THE PROBLEM. THE IAC VALVE WAS REPLACED, AND THE COMPUTER WAS REPROGRAMMED. NEITHER OF THESE EFFORTS REPAIRED THE PROBLEM. *AK
PROBLEMS WITH MY WIFE'S 2002 MERCURY GRAND MARQUIS LS NOT CRANKING AT ODD TIMES. I HAVE CRANKED UP THE CAR, AND DRIVEN IT INTO THE GARAGE, THEN GO BACK OUT A COUPLE MINUTE LATER - 15-30 MINUTES - AND THE CAR WOULD NOT CRANK. THE LAST TIME I PULLED THE CAR INTO THE GARAGE ONE EVENING AND WHEN MY WIFE WENT TO GO TO WORK THE NEXT MORNING IT WOULD NOT CRANK. THE DEALER'S SERVICE DEPARTMENT CAN NOT FIND A PROBLEM. HOWEVER, THE LEFT TURN SIGNAL WENT OUT ABOUT A YEAR AGO, REQUIRING A MODULE BE REPLACED. AFTER THAT WE NOTICED THE FOOT PEDAL ADJUSTMENT DIID NOT WORK AND A LOOSE CONNECTION WAS FOUND TO BE THE PROBLEM. THE STARTING PROBLEMS DID NOT START UNTIL AFTER THE TURN SIGNAL MODULE WAS REPLACED. I HAVE FOUND OTHER INCIDENTS OF PROBLEMS WITH THE IGNITION SWITCH FOR THIS MODEL MERCURY. *AK
