I have had three spark plugs that blew out of the head. Ford does not state that this is a problem and the cost for repair is on the owner.

At 90,000 miles after my first "tune up" I blew a spark plug off of my head on my 2000 Ford Excursion. I was told by my local mechanic and many other people that Ford's in this year range have been streaming into his shop with blown spark plugs. I also stated that Ford is refusing to recognize this huge safety issue and that the government needs to get involved. Please take this complaint seriously. My wife and 5 kids were in the car in a unknown area to them at 10:00pm when this breakdown occurred. This story is very similar to 1000's of other stories on the internet. Just type in "blew a spark plug" into a search engine and start reading.

I had been out of town when my 2000 Ford Excursion had a door ajar dummy light fail to shut off. I attempted to figure out what was causing the door ajar light to remain on but never did find the problem. I ended up driving home so I could make an appointment with my dealer to have it checked out. I was able to get the truck home, but as I was driving through my subdivision my truck made a noise, then made a much louder noise, and began running really rough. A strong odor of fuel filled the passenger compartment of my truck. I immediately shut off the engine so my truck wouldn't ignite, but that left me stranded in the middle of the road. I have since been told that the Triton V10 engine blew a spark plug and it's been quoted at $4200 to be repaired at the closest dealership and $3500 at the dealership where I purchased the truck but I have to have it towed again.

I own a Ford Excursion with a 6.8 V10 motor. While traveling on an interstate at posted speed one or more (waiting to here from repair shop) spark plugs were blown from the cylinder head without warning and could have caused a very serious accident. Fortunately at the time I was able to pull over to the side of the road safely just avoiding a fast over taking Transport truck. From what research I have done on the internet this is an all too common problem with the Ford V10's and some V8's. I am now looking at a minimum of a replacement head and it might require a replacement motor. This is a safety issue and could have ended in an accident or fire.
