2007 MERCURY MOUNTAINEER Complaints

WHEN TRAVELING IN "OVERDRIVE", UPON ACCELERATION, THE TRANSMISSION WILL BUCK, VIOLENTLY DEPENDING HOW HARD YOU PRESS ON THE PEDAL. THE ONLY TIME THIS WILL NOT HAPPEN IS IF YOU CONTROL THE VEHICLE SPEED WITH THE CRUISE CONTROL. I HAVEN,T HAD IT GO TO THE DEALER AS OF YET FOR INSPECTION, SO THERE ARE NO CONCLUSIONS AS OF YET AS TO WHAT MAY BE WRONG. *TR

DISCOUNT TIRE COMPANY INFORMED ME THAT THEY HAD A TECHNICAL BULLETIN - WHEEL ADVISORY THAT SAID; "DO SERVICE THE MERCURY MOUNTAINEER 18" OE WHEELS (2005 AND NEWER) THEY FOUND IN TESTING THAT THE FRONT BEAD HUMP HAS A RIDGE ON THE BALCONY LEDGE WHICH CAN CAUSE BEAD DAMAGE WHEN MOUNTING. TESTS WERE CONDUCTED WHERE SEVERAL TYPES OF TIRES WERE MOUNTED AND INFLATED ON THE OE WHEELS. THE ONLY TIRE THEY WERE ABLE TO SEAT AT (50PSI) WAS THE ORIGINAL EQUIPMENT MICHELIN. AFTER MOUNTING AND FOUND THAT IT HAD A DAMAGED BEAD. DURING THE TEST, THEY WERE NOT ABLE TO GET A TIRE TO SEAT WITHOUT DAMAGING THE BEAD. THE RECOMMENDATION: DO NOT SERVICE THESE WHEELS. CENTRAL FLORIDA LINCOLN DEALER (FORMERLY CENTRAL FLORIDA LINCOLN MERCURY) DID NOT HAVE ANY SERVICE BULLETIN ON THIS PROBLEM. THE ONLY WAY I COULD GET NEW TIRES FOR MY MERCURY MOUNTAINEER WAS TO BUY NEW 17" WHEELS AND HAVE NEW TIRES MOUNTED ON THEM. *TR

TL* THE CONTACT OWNS A 2007 MERCURY MOUNTAINEER. WHILE DRIVING APPROXIMATELY 40 MPH, THE FRONT DRIVER'S SIDE SEAT MOVED BACKWARD AND FORWARD INDEPENDENTLY. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN WAS ABLE TO DUPLICATE THE FAILURE AND RECOMMENDED REPLACING THE IGNITION. THE TECHNICIAN ADVISED THAT IF THE FAILURE CONTINUED, THEN THE SEATING HARNESS WOULD HAVE TO BE REPLACED. THE CONTACT HAD THE TECHNICIAN DISCONNECT THE SEAT. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 52,000.

WHEN BRAKING THE VEHICLE ACCELERATES, WHEN SLOWING DOWN TO A STOP SIGN OR A RED LIGHT AND IT HAPPENS WHEN PARKING FORWARD OR REVERSE. I RECENTLY PURCHASED THE VEHICLE 8/2012. I AM VERY DISPOINTED BECAUSE I REALLY LIKE THIS SUV. I HOPE THE DEALER WILL FIX THIS SPEED CONTROL PROBLEM FREE OF CHARGE BECAUSE THIS SITUATION COULD GET DANGEROUS. *TR

WE BOUGHT THE CAR 2 YEARS AGO AND A FEW MONTHS AFTER WE HAVE PURCHASED IT, IT STARTED TO ACT UP. WHEN WE PULL THE SHIFT GEAR TO REVERSED, IT JERKS REAL BAD AS IF WE WERE REAR ENDED. A FEW TIMES, THE SHIFT GEAR WOULD BE STUCK. WE COULD NOT PULL THE SHIFTER DOWN TO REVERSE FROM PARK. IT NORMALLY TAKES US AN HOUR SO TO DO IT BUT TONIGHT, IT WAS WORST. WE WERE STUCK ON PARK...FINALLY AFTER AN HOUR, WE WERE ABLE TO PULL IT FROM PARK AND ONTO REVERSE FROM THE GARAGE. ONLY THIS TIME REVERSE WAS PARK, NEUTRAL WAS REVERSE, DRIVE WAS NEUTRAL AND 3 WAS DRIVE. IT WAS SO FRUSTRATING....AND TO TOP THAT OFF, MY HUSBAND AND I BOTH GOT INTO A HEATED ARGUMENT OVER THIS STUPID CAR!! WE STILL CANNOT GET IT FIXED BECAUSE WE DON'T HAVE THE MONEY!!! *TR

I WAS DRIVING ON THE HIGHWAY AND NOTICED THAT MY STEERING WAS NOT WORKING WELL. MY ENGINE WAS OVERHEATING AND EVENTUALLY SHUT OFF. I HAD TO PULL OVER ON THE SIDE OF THE HIGHWAY. WHEN I GOT SOMEONE TO LOOK AT THE CAR, WE REALIZED IT HAD NO COOLANT. WE FILLED UP THE COOLANT AND EVERYTHING SEEMED FINE. ABOUT A MONTH LATER I NOTICED THAT THE ENGINE WAS MAKING THE SAME NOISE AS IT HAD BEFORE AS IF IT WERE WORKING TOO HARD. I CHECKED THE COOLANT AND IT WAS COMPLETELY EMPTY AGAIN. I HAVE A FRIEND WHO ALSO OWNS THE MM AND HAD THE SAME PROBLEM. THE REPAIR AND COST OF A NEW RADIATOR WAS 1500. FORD/MERUCY NEEDS TO DO A RECALL ON THIS PRODUCT AND GET IT TAKEN CARE OF. I JUST PURCHASED THIS CAR IN JANUARY AND SHOULD NOT HAVE TO BE SPENDING SO MUCH MONEY ON A REPAIR. *TR

MY TRANSMISSION JERKS AS I ACCELERATE DURING TRAVEL. TO ME IT'S GETTING WORSE. I HAVE HAD IT LOOKED AT. NO CODES ARE SHOWING THAT I HAVE A PROBLEM. BUT CLEARLY SOMETHING IS WRONG. I HAVE DONE THIS SEVERAL TIMES, STILL NO CODES TO INDICATE ANYTHING IS WRONG WITH MY VEHICLE. ALSO MY GAS SENSORS ARE SHOT. ENGINE LIGHT GOES IN AND OUT. MY VEHICLE HAS STOPPED IN THE MIDDLE OF ATLANTA TRAFFIC, CAUSING PROBLEMS OF OTHER VEHICLES TRAVELING IN THE DIRECTION THAT I AM WITH CHILDREN. I ALSO HAVE THE PROBLEM WITH BACKING MY VEHICLE, IT JERKS BEFORE BACKING. *TR

WHILE DRIVING ON A FEW DIFFERENT OCCASIONS NOW, MY DRIVER'S SEAT WHICH IS POWER OPERATED MOVED BACKWARDS ON ITS OWN AND THE INTERIOR LIGHTS CAME ON. I HAD TO READJUST THE SEAT MYSELF AND THEN THE INTERIOR LIGHTS WENT OUT ONCE THE SEAT WAS READJUSTED. THE FIRST TIME IT HAPPENED I THOUGHT IT WAS JUST A FLUKE AS I HAVE ONLY OWNED THIS VEHICLE A LITTLE OVER A MONTH. IT HAS HAPPENED MAYBE 4-5 TIMES NOW. TODAY I WAS GOING AROUND A CURVE IN THE ROAD AND IT HAPPENED. IT REALLY COULD HAVE CAUSED AN ACCIDENT BECAUSE IT WAS ON THE INTERSTATE AND I WAS TRAVELING 55-60 MPH. *TR

WHILE DRIVING AT ANY SPEED THE SEAT WILL GO BACK TO ITS PARKED POSITION AND THE INTERIOR LIGHT COMES ON AS IF THE CAR WAS SHUT OFF. YOU TOUCH THE KEY IGNITION AND THE SEAT GOES BACK TO DRIVING POSITION AND THE LIGHT GOES OUT. *KB

TL* THE CONTACT OWNS A 2007 MERCURY MOUNTAINEER. THE CONTACT WAS DRIVING APPROXIMATELY 50 MPH WHEN A VIBRATION WAS FELT AND THE TRANSMISSION BEGAN TO SLIP GEARS. THE FAILURE APPEARED TO OCCUR MORE FREQUENTLY IN WARM WEATHER TEMPERATURES. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER BUT THE TECHNICIAN WAS UNABLE TO DUPLICATE THE PROBLEM. IN ADDITION, THE INSTRUMENT PANEL AND GAUGES WOULD ILLUMINATE INTERMITTENTLY AS A RESULT OF DEFECTIVE PIXELS. THE FRONT DRIVER'S SIDE POWER SEAT WOULD MOVE BACKWARD AND FORWARD FREELY WHILE THE VEHICLE WAS IN MOTION. THE CONTACT WOULD SHUT OFF THE VEHICLE AND ONCE RESTARTED, THE FAILURES WOULD CORRECT INDEPENDENTLY UNTIL LATER RECURRING WITHOUT WARNING. IN ADDITION, THE HEADLIGHTS FAILED INTERMITTENTLY. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED FOR THE FAILURES. THE MANUFACTURER WAS NOTIFIED OF THE DEFECTS. THE APPROXIMATE FAILURE MILEAGE WAS 46,000.
