NHTSA Complaint #10458501 — 2008 FORD F-150

HAD A P/M CHECK DONE ON MY VEHICLE BY MY MECHANIC. DURING THE CHECK, HE INFORMED ME THAT THE IGNITION COIL FOR CYLINDER 5 WAS GOING OUT. HE ADVISED THAT THIS WAS COMMON. HE ALSO ADV THAT HE NEEDED TO REPLACE THE SPARK PLUG BUT HE DID NOT WANT TO UNTIL I CHECK INFO ON THE 9/16 PLUG ON-LINE. THIS PLUG HAS HISTORY OF BREAKING (DESIGN FLAW- CARBON FUSING/REPLACEMENT MC PLUGS HAVE BEEN REDESIGNED) BASED ON INFO IN VARIOUS FORUMS. THE PLUG DID BREAK DURING EXTRACTION REQUIRING ADDITIONAL WORK/EXPENSE. CALLED A LOCAL FORD DEALER SERVICE MGR WHO ADVISED HE WAS UNAWARE OF THAT HAPPENING BEFORE 80K MLS. AN EMAIL TO FORD REVEALED THAT THEY ARE UNAWARE OF ANY PROBLEMS/RECALLS OR TSB (WHICH DO EXIST). IN OTHER WORDS, THEY WILL NOT DO ANYTHING. I AM NOW WORRIED ABOUT PLUGS BREAKING DURING SCHEDULED TUNE RESULTING IN ADDITIONAL EXPENSE EVEN AT FORD DEALER .(AS PER COMMENTS ON LINE FORUM) THIS IS CLEARLY A DESIGN FLAW W/ MOTORCRAFT PLUGS AND THEY KNOW IT (TSB'S) CAN YOU HELP? *JS
