NHTSA Complaint #10838457 — 2007 FORD F-150

SPARK PLUG BLEW OUT. MECHANIC REPLACED IT FOR $350 THEN IT BLEW OUT AGAIN 2 DAYS LATER. PROBLEM WITH FORD SPARK PLUG TEARING THREADS OUT AND NOT BEING ABLE TO REPLACE SPARK PLUG WITHOUT REPLACING ENTIRE ENGINE. MY SON WAS ON HIS WAY BACK TO COLLEGE (5HR DRIVE) WHEN THE SPARK PLUG BLEW. IT SOUNDED LIKE A SHOTGUN! HAD IT TOWED TO MECHANIC AND THEY REPLACED SPARK PLUG AND 2 DAYS LATER SAME ONE BLEW AGAIN WHILE DRIVING TO WORK. TOWED A SECOND TIME AND MECHANIC IS SEARCHING FOR WAYS TO RESOLVE. HE SAYS WE MAY HAVE TO REPLACE ENTIRE ENGINE BECAUSE OF THREADS BEING STRIPED WHEN IT BLEW OUT. FORD MECHANIC HAS LOOKED AT AND DOES NOT HAVE ANY SOLUTIONS. IN RESEARCHING ONLINE I HAVE DISCOVERED THAT THIS COULD HAVE POTENTIALLY BEEN VERY DANGEROUS. OTHERS WITH SAME PROBLEM HAVE HAD ENGINE FIRE WHEN SPARKPLUG BLEW. WE WERE IN PROCESS OF SELLING VEHICLE SO NOW WE ARE SOL! WE DON'T HAVE $4000 TO REPLACE ENGINE AND OUR FAMILY NEEDS A 2ND CAR. NEVER AGAIN WILL I BUY A FORD. THEY DO NOT STAND BEHIND THEIR PRODUCT!
