Complaint / review text:
2003 Ford F-250 Lariat V-10. The spark plug blew out at 75,000 miles. I had dealer install helicoil to replace and torque all other spark plugs. Six months later, another plug blew out yesterday while on freeway. 2003 Expedition 5.4L blew out a plug at 65,000 miles. That's two vehicles, both 2003 Fords blew out three plugs in the last 6 months. I am more than irritated. Lifelong Ford loyalty is going out the window. The warranty covered 2003 Expedition. $1,200 for the first repair on the 2003 F250, waiting for dealer response on the 2nd blowout.
