NHTSA Complaint #10272595 — 2002 FORD F-250 SD

I PURCHASED AN F250 2002 TRITON V8 SUPER DUTY MID YEAR 2007. LESS THAN A YEAR AFTER THE PURCHASE A SPARK PLUG BLEW OUT OF THE MANIFOLD. THIS ALL HAPPENED UNDER NORMAL HIGHWAY DRIVING CONDITIONS. THE DEALER PUT IN AN INSERT, RETHREADED IT AND REPLACED SPARK PLUG. ALMOST A YEAR TO THE DAY IT HAPPENED AGAIN. SO NOW #2 & #4 HAVE BLOWN OUT. ON 5/30/09 A THIRD ONE BLEW OUT. ALL ON THE LEFT SIDE (PASSENGER SIDE) OF THE MANIFOLD. SO NOW #2, #3 AND #4 HAVE BLOWN OUT. I RESEARCHED THE INCIDENT ONLINE AND HAVE FOUND 500 OTHER CASES. I'M CURIOUS HOW MANY ARE REALLY OUT THERE THAT WEREN'T REPORTED. I'VE BEEN FORTUNATE BECAUSE IN SOME CASES THE SPARK PLUG BLEW THROUGH THE HOOD OR DAMAGED THE MANIFOLD. I DO HOWEVER WONDER WHAT DAMAGE IS OCCURRING EACH TIME IT HAPPENS. HOW MANY REPORTS OR HOW MANY VEHICLES DOES IT TAKE BEFORE THERE'S A RECALL? EVEN THOUGH I HAVE EXTENDED WARRANTY I'VE BEEN CHARGED A DEDUCTIBLE EACH TIME AND NOW FACE A THIRD IF MY WARRANTY IS STILL GOOD. I HAVE ONE MORE PLUG ON THAT SIDE THAT HASN'T BLOWN YET AND SINCE THIS ONE WAS ONLY 7 MONTHS SINCE THE LAST ONE I SUSPECT I'LL BE PAYING AGAIN. I SAW ONLINE WHERE IT WAS SUGGESTED AS A PISTON PROBLEM. *TR
