NHTSA Complaint #10298380 — 2002 FORD F-150

IN MY CASE THERE WERE THREE SEPARATE OCCURRENCES WHERE MY SPARK PLUGS SHOT OUT OF MY ENGINE. THE FIRST TIME IT HAPPENED ON THE HIGHWAY CRUISING ALONG ABOUT 70 MPH. I ACTUALLY THOUGHT I BLEW A TIRE.THIS WAS AT NIGHT SO IN THE MORNING I CHECKED IT OUT WITH A FRIEND'S HELP AND SAW THE PLUG SITTING RIGHT WHERE IT WASN'T SUPPOSED TO BE. SO WE WENT AND BOUGHT A NEW PLUG AND COIL PACK AND THREADED IT BACK IN AND BELIEVE IT OR NOT IT STAYED THERE AND STILL IS THERE TODAY. THIS FIRST TIME WAS ROUGHLY 3 1/2 YRS AGO. THE NEXT TIME IT HAPPENED WHILE MY SAME FRIEND WAS DRIVING MY TRUCK TO HIS HOUSE BUT THIS TIME IT WAS A DIFFERENT PLUG AND WE WEREN'T SO LUCKY THREADING IT BACK IN. THE THREADS WERE STRIPPED OUT SO WE HELICOILED IT BACK IN OURSELVES AND IT IS STILL THERE TODAY. THIS SECOND TIME WAS ROUGHLY 2 YRS AGO. THE LAST TIME HAPPENED IN A PARKING LOT RIGHT AS I STARTED MY TRUCK UP.THE PLUG ACTUALLY HIT THE UNDERSIDE OF THE HOOD WHEN IT BLEW. SO AGAIN I BOUGHT A NEW PLUG AND COIL PACK AND LUCKILY IT THREADED BACK IN AGAIN. SO NOW I AM VERY GUNSHY NATURALLY EVERYTIME I DRIVE IT. TO PROPERLY CORRECT THIS PROBLEM IT WOULD COST A SMALL FORTUNE AND TO SELL IT AS IS WHO WILL BUY IT. ALSO ON THIS SAME VEHICLE MY TRANSMISSION BLEW AT 39,000 MILES WHEN THE WARRANTY RAN OUT AT 36,000 NATURALLY I WAS TOLD THERE WAS NOTHING THEY COULD DO. THAT COST ME $3,500 AND A WEEK STRANDED. I HAD TO HAVE A NEW TRANSMISSION INSTALLED AT A DEALERSHIP. THE TRUCK IS A F150 HARLEY DAVIDSON EDITION. IT NOW HAS ROUGHLY 94,000 MILES ON IT. THE DATES ARE ALL APPROXIMATE ALONG WITH THE MILEAGE WHEN THEY OCCURRED. *TR
