“TL* THE CONTACT OWNS A 2010 MERCURY GRAND MARQUIS. THE CONTACT STATED THAT THE AIR CONDITIONING UNIT FAILED AND WOULD ONLY EMIT AIR FROM THE DEFROSTER AND UNDER SEAT VENTS. THE CONTACT ALSO STATED THAT THE TRUNK LIGHT ILLUMINATED EVEN THOUGH THE TRUNK WAS CLOSED. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THE AIR CONDITIONER AND TRUNK LATCH NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 63,000. UPDATED 09/05/13*LJ”
“SPLICING ON ALMOST ALL ELECTRICAL SYSTEMS HAD COME APART. AFFECTED WERE THE RADIO, CLOCK, WINDOWS, POWER SEATS, LIGHTS, DOOR LOCKS, TRUNK RELEASE INSIDE CAR, LOW TIRE MONITOR WARNING LIGHT STAYED ON CONSTANTLY, SEAT BELT WARNING LIGHT STAYED ON, WARNING BELL FOR KEY IN IGNITION STAYED ON EXCEPT WHEN CAR WAS MOVING, DOME LIGHT WOULD NOT GO OFF WHENEVER YOU GOT OUT OF CAR. SOME OF THESE PROBLEMS WERE CONSTANT AND SOME WERE INTERMITTENT. AS A RESULT OF THE LOCKING PROBLEM, OUR VEHICLE WAS STOLEN, BUT THANKFULLY FOUND WITH NO DAMAGE. WITH NO HELP FROM OUR LOCAL FORD DEALER, I FINALLY CALLED THE FORD MOTOR CO. COMPLAINT DEPT. AND WAS TOLD TO GET A DIAGNOSTIC TEST RUN ON IT, WHICH I DID AT ANOTHER DEALERS, AND THAT IS WHEN THEY FOUND THE WIRING SPLICING PROBLEM. AS A RESULT OF THE ELECTRICAL PROBLEMS, IT HAS BLOWN THE MOTORS WHICH CONTROL BOTH THE POWER SEATS. I HAVE HAD THE WIRING FIXED BUT NOT THE MOTORS REPLACED DUE TO THE EXPENSE INVOLVED. I FEEL LIKE I HAVE A REAL LEMON ON MY HANDS AS WELL AS AN UNSAFE VEHICLE. *TR”
