As I was driving home, my engine began making a loud noise & running badly. Upon inspection of the motor, I found the spark plug had blown out of the #3 cylinder, breaking the coil pack in the process. I do not believe this is a normal occurrence. I have checked on-line to see if this has happened to other F-150 owners, and found out it is fairly common. What can be done to get Ford to help with this problem?

On a return trip from columbus Ohio to new orleans la, a spark plug ejected from #3 cylinder, passenger side second from the front. Engine stalled but was able to be restarted. Smell of fuel was very prevalent. No other apparent damage to any other systems on the engine. Plug was the original factory installed plug and had not been touched by any mechanic since the truck was new. Brought to the dealer. After a $700 repair bill, they tried a helicoil, but this failed after just 1 use of the truck on the highway.. a $28,000 truck should be able to keep its spark plugs in the heads.

The contact owns a 2003 Ford F150. The contact stated that while driving 65 mph, the spark plug was blown on the number four cylinder. There were no warning lights illuminated. The vehicle was towed to a mechanic, who replaced the spark plugs at a cost to the contact. The failure recurred after the repairs. The vehicle was then towed to the dealer, where the contact was awaiting a second spark plug replacement. The manufacturer was contacted and advised that there was no failure, offering no assistance. The failure mileage was 140,000.

Spark plug ejected from the cylinder upon routine vehicle starting. Vehicle was warm when started. Once the spark plug ejected I noticed the smell of gasoline and smoke. A small fire was easily extinguished however could have been severe.
