Expedition XLT 5.4L V8

  • Automatic transmission
  • 62,979 miles


the cost of this fix should have been around 700.00 (or under) for a HELICOIL - they (FORD DEALERSHIP) did the "while we are in there" approach and charged for everything - without asking - just "we have to" 1973.86 (almost triple)

Now 3-1/2 years later the same cylinder (I'm guessing #3) blows the spark plug - stripping the threads again - and I am responsible for the repair (3600.00 +tax) ABOUT $4000.00 for a new cylinder head and "while we are in there" Please post yours also so we get SOMETHING out of this - Thanks

Had car in dealership exactly four months ago- had it in for a crank case problem / transmission slipping. $1,800.00 later, (and when truck was returned to us) engine was running very rough. Not even out of the dealers driveway, we returned the truck because the engine light turned on (this light has never come on since we bought the truck). Dealer diagnosed the problem as #3 spark plug defective and wanted $300.00 more to repair. We paid half after extensive arguing. Spark plug was repaired- engine light still on because dealer claimed engine needed tune up. Drove until four months when spark plug blew out of engine while on highway. When on side of road and hood open, started engine and fireball shot out of front right side of engine (where spark plug was coil was supposed to be). Shut engine off, paid $250.00 for towing. Never moved car since.....

I have a 1999 Ford Expedition Eddie Bauer Edition, While driving with my wife, all of sudden I heard this loud pop sound came from the engine, followed by loud rat-tat-tat

sound. got so scared i immediately pulled over, investigate what happen i notice the spark cable was hanging and split in 3 pieces and the spark plug was just sitting on top of the engine, it was very upsetting because i never heard such a thing, i had it towed to local Ford dealer and the service manager told me that this a common problem on Ford, that the spark plug will blow out, due to ford's poor engine design. While ford is blaming

the dealership technician from over torquing of the new plugs, the dealership on the other hand i s blaming Ford Company for their poor engine design, for the mean time we are the one who got stock paying for this outrageous charges. This repair had cost me $2644.53, i know others pay way more than this. Ford Company should realized that this problem is due to engine poor design, with so many complaint documented all over the Nation, Ford company should stop blaming others, and the Federal Government should step up to help the consumer resolved this problem, because this could be an emission problem.

Once again I have had another spark plug ejected from my cylinder head. I am furious that Ford knows they have a problem, but because of the expense involved in replacing both heads they choose to let consumers bear the burden of their poor design. This is unconscionable situation and a telling position which shows how committed Ford is to their customers.

This was the first I'd heard of this problem. Decided to try and trade it in and another plug blew out. It's in the shop again! This time I'm selling it fast on Craigslist!

On our way from Virginia to Washington my family experienced a spark plug blow out. We were able to have it fixed at a Ford Dealership in Little Rock, but it put us $500 and 2 days behind schedule (plus the cost of food and hotel rooms). The service rep at Ford was able to tell what the problem was immediately after I told him what vehicle I was driving. This is so common that there are companies making a fortune selling repair kits to fix Ford's screw up.

Ford can make all of the excuses they want, but it still their responsibility to produce a safe vehicle and they have let their customers down. This vehicle will end any further relationship with Ford by any member in my family.

Expedition 5.4L V8

i started my 99 ford expedition this morning to a loud BOOM followed by what sounded like a helicopter flying under the hood of my engine!!! then noticed grey ish smoke coming out from under the hood !! after inspecting the engine i discovered that the second from the rear passenger side spark plug had blown out of the engine and was hanging by the coil wires. after contacting some local southern california mechanics i found out that this is a major issue and VERY common problem. i decided to look online to see if i could possibly fix this problem my self to save the $500 ( per spark plug/cylinder ) only to find out that this a MAJOR problem in the design by ford motor in hind sight i can say that i did hear a sound coming from the engine prior to this disaster, i took the sound to be an exhaust leak coming from the passenger side. well i was wrong!! i found out that it was a spark plug on its way to play POP goes the weasel......but all jokes aside, im just a working family man with little money for repairs such as this. i keep up on my vehicles and never neglect servicing them.... but this is a serious and dangerous issue that can be harm full and potentially deadly.if something were to have happen to my family due to the negligence of an obvious manufacturing defect such as this, i dont know what i would do!!! .............

as it is i would consider hanging out at my local ford dealership reving up my engine in front of the showroom floor with my plug dangling by wires and sounding like a harley davidson is doing doughnuts under my hood.........bunch of crap!! ive emailed DONALD RICKETTS ( a lawer in southern cal who started a suit ) about this as well.

I was on a long trip with my family about 110 miles from home when the spark plug in my #2 cylinder blew out scared the sh*t out of me. i limped it home and went to napa auto parts and they had a kit just for this problem. it cost $75.00 bucks. its an adapter that cuts its own threads down the spark plug hole without getting any shavings in the cylinder you leave it there it comes with an extra long spark plug that threads in to the adapter and a shorter plug wire. permanent fix works great

The is the third time this year that spark plugs have been blown out of the engine.

On my way home from Kansas to Colorado after enjoying some leave time before I deploy to Afghanistan. Got 100 miles from home heard a loud pop and then a sound like a flat tire but it wasn't. The spark plug had blown out of the head, stripped the threads and broke the coil. Had my wife 3 kids and 2 dogs, what a good time.

3 spark plug blew out damaging the coil. I have read that this is a common problem with the 5.4l triton engines. If this is so common why not recall the engine and give the people that still have some faith with fords a break. I took it to the ford garage and they gave me 3 options 1. heeley coil it, but they will not guarantee the work.

2. Buy a new head and that will cost me $3000.

3. Buy a new motor and that will cost me $6000. I don't know about everyone else but I think someone is getting screwed!
