I HAD TAKEN MY VEHICLE TO THE DEALERSHIP ON THREE SEPARATE OCCASSIONS DUE TO COOLANT LOSS AND THE TEMPARATURE GUAGE READING COOL. ON EACH OCCASSION THEY REPLACED THE THERMOSTAT. THE LAST TIME WAS JUST PRIOR TO THE EXPIRATION OF THE EXTENDED WARRANTY. I SPECIFICALLY REQUESTED THAT IT BE TESTED AND CHECKED THOUROUGHLY BECASUE I DID NOT WANT TO REPLACE AN ENGINE AFTER THE WARRANTY EXPIRED. THEY REPLACED THE THERMOSTAT. SHORTLY AFTER I EXPERIENCED THE SAME DIFFICULTY. I TOOK THE VEHICLE TO A PRIVATE GARAGE AND THEY REPORTED THAT THE HEAD GASKETS HAD FAILED AND WERE LEAKING. I CONTACTED THE SERVICE MANAGER AT THE DEALERSHIP AND HE REQUESTED THAT I BRING THE VEHICLE TO THEM FOR TESTS. SEVERAL DAYS LATER THE SERVICE DEPARTMENT CALLED AND INFORMED ME THAT THE HEAD GASKETS HAD FAILED AND THAT COOLANT WAS ENTERING THE CYLINDERS. THEY OFFERED TO REPLACE THE ENGINE FOR $4600.00. NOT GOING TO HAPPEN.*AK

ON FEBRUARY 16, 2004 AT APPROXIMATELY 2:30 PM I WAS PULLING MY WIFE'S 1997 FORD EXPLORER SPORT INTO A DIAGONAL PARKING STALL. I HAD ALMOST COME TO A COMPLETE STOP WHEN THE ENGINE BEGAN TO ROAR AND THE CAR BEGAN TO ACCELERATE AGAINST MY BRAKING. I PRESSED AS HARD AS I COULD ON THE BRAKE PEDAL BUT THE CAR CONTINUED TO MOVE FORWARD UNTIL IT STRUCK A CAR OPPOSITE MY PARKING STALL. I PUSHED THE GEAR SHIFT INTO NEUTRAL AND TURNED OFF THE ENGINE. I CHECKED MY RIGHT FOOT POSITION AND CONFIRMED THAT I WAS ONLY PRESSING ON THE BRAKE PEDAL. WHEN I RELEASED THE BRAKE PEDAL THE CAR ROLLED BACK A COUPLE OF FEET. I SHIFTED THE CAR INTO PARK AND RESTARTED THE ENGINE AND BACKED THE CAR UP ANOTHER 3 FEET. THE SUDDEN ACCELERATION HAS NOT RECURRED BUT I AM CONCERNED THAT IT MIGHT AGAIN. *JB
