NHTSA Complaint #10088720 — 1999 FORD EXPEDITION

WHILE I WAS DRIVING ON THE EXPRESSWAY AT EXPRESSWAY SPEEDS ALL OF A SUDDEN THERE WAS A POP SOUND AND THE VEHICLE LOST POWER AND STARTED VIBRATING BADLY. WHEN GOT VEHICLE TO MECHANIC BY TOW TRUCK BECAUSE VEHICLE HAD NO POWER, IT WAS REVEALED TO ME THAT THE SPARK PLUG WAS BLOWN OUT THE HEAD OF THE MOTOR. IT WAS THE 3RD PLUG ON THE PASSENGER SIDE. MY VEHICLE HAS A COMPLETE EXTENDED WARRANTY BUT THE WARRANTY COMPANY CLAIMS THAT THIS IS DUE TO A LOOSE SPARK PLUG. THEY ARE THE ORIGINAL FACTORY PLUGS SUPPOSEDLY YOU DON'T HAVE TO TOUCH THEM FOR 100,000 MILES. MY MECHANIC STATES THAT THIS HAPPENED DUE TO A DEFECT IN THE HEAD BECAUSE HE NOT ONLY SPOKE TO FORD MECHANICS BUT HAS SEEN THIS BEFORE. THIS IS A COMMON PROBLEM, UPON RESEARCHING THIS MYSELF I FOUND MANY OTHER PEOPLE ON THE INTERNET WITH THIS SAME PROBLEM,AT THE SAME EXACT SITE ON THE MOTOR. THIS IS A PROBLEM WITH THE HEAD OF THE MOTOR AND MY WARRANTY COMPANY SHOULD FIX MY TRUCK BECAUSE THIS IS A COVERED ITEM IT IS THE ENGINE BLOCK THAT MALFUNCTIONED , NOT THE SPARK PLUG!!!! PLEASE HELP BECAUSE THIS IS A VERY COSTLY REPAIR. *JB
