I have a 1999 ford expedition that has continuously blown spark plugs, i have had it repaired several times at a local dealership. I keep my vehicles maintained on a regular basis, and i have no warnings leading up to the spark plug blowing. I am afraid that one of these times it will blow and my engine will catch on fire. I am very disappointed with ford, that they have not done anything to resolve this issue,…

On my way home from kansas to colorado when we heard a sound like a flat tire but it wasn't. My spark plug had shot out of my cylinder head. This could have caused fuel to spray out and start a fire. This is a common problem with the triton 5.4l engines, but there has not been a recall or anything to fix it. *tr

1999 ford expedition with the 5.4l triton engine blew out a factory installed original spark plug causing a engine fire. This seems to be common among this particular engine. Ford will not acknowledge a defect in the design, but online research concludes this problem is widespread and very dangerous. Ford should be compelled to recall these engines and repair or replace the engine at no cost to the customer. *tr

I have a v8 triton 5.4l which has blown a spark plug from the engine block. I was not putting undo stress or wear and tear on my engine when this occurred. I kept maintenance up on my vehicle so therefore this should never have been an issue. There was no accident as i was able to pull over and out of the way of traffic but this could be potentially dangerous since fuels being expelled into the engine and a spark…
