This is not right this truck still had the original plugs and coil packs. tonight coming home from the store with my wife and baby son the spark plug ejected causing a pop and a loud sound like a exhaust leak . This has happened on the #3 as well as the #1 in the past now it's the number 5. This is time consuming and expensive. Ford should be ashamed at this. I love my truck and will fix this issue but damn you Ford.

Update from Jul 29, 2018: had to retap the number 10 cylinder with the CalVan kit so far so good the insert is thick and seems this will be a permanent solution

I feel that Ford needs to take a close look at 2000 model excursion for making this make a lemon law definite; many reasons starting with this spark plug issue, steering wobble my lady is scared to drive this vehicle which means I am the one to drive this dangerous machine, alignment issue is another area in which constant maintenance is required often at 250$ each tire, the gas gauges don't work.... I have stressed myself maintaining this vehicle day after day; I love ford but action needs to be taken as this track record continues to follow the same pattern and endanger peoples lives or families. This family vehicle is not safe its a lemon that is more than sour its bitter and I can't believe that ford doesn't take ownership for this horrible make and model its a shame we must risk our lives to recognize that something is not safe. in all honesty i have a ford excursion that i don't feel is safe even selling now that's all F'd up. FORD NEEDS TO DO SOMETHING IN REGARDS TO THIS PARTICULAR MAKE AND MODEL PEOPLE OUT THERE DO NOT BUY 2000 FORD EXCURSION SAVE YOURSELVES DON'T PUT YOURSELVES IN HARMS WAY BECAUSE THATS WHAT THIS MAKE AND MODEL IS PLACING INTO YOUR LIVES OR FAMILIES LIVES!!!!!!!!

I found out after buying the Excursion that spark plug blowing is a common problem. It happened 6 months ago with 160k miles to the #3 passenger side plug. Spent almost 1k repairing it at a Ford Dealership.

Here it is 6 months and 6000 miles later and THE SAME plug has blown again. They re-drilled and put a larger coil insert in the plug hole but it blew out immediately. Now they want $4300 to replace the cylinder head on a car that is barely worth $4000!!! The service adviser says he has never had a repair blow out a second time, yet, somehow the warranty to fix the problem if it happens a second time during the warranty period/mileage, mysteriously goes away if the fix is more expensive???

I asked what was more probable on a repair that works the 1st time nearly every time, 1) that there is some mysterious problem with the cylinder head that is my problem, or that 2) they made a mistake drilling and putting the insert in the 1st time which has now ruined the cylinder head? Heard nothing but crickets as far as an answer to that one.

I am left with 2 solutions. With a less than generous offer to reduce my out of pocket now by $500, I can pay $3800 and try and sell it for $4000, netting $200, or I can tow it to a junk yard and get maybe $200. Both options suck. I cant believe with so many Ford V10 owners having this problem, and the fire threat when it happens, there has been no recall or class action.

Guess I'll just have to take it! Unbelievable!

I owned this vehicle since new in Jan 2000. It has almost 200,000 miles on it. I changed the spark plugs at 100,000 miles and never had an issue before this, so Ford;s claim of improperly installed spark plugs being the cause is utter bullshit.

This is my fist experience with this problem and was amazed when I started researching the problem on the Internet to find the huge number of forums and complaint sites dedicated to this problem.

How Ford can be in denial is beyond comprehension. It was a design flaw, clear and simple. If it wasn't, then explain why Ford redesigned the threads on the later built heads?

I've seen there are a couple of class action lawsuits filed against Ford for this problem, but I think that there should be one national lawsuit to make Ford pay for these repairs. My estimate from a dealer is $600 labor plus parts.

I WILL NEVER BUY ANOTHER FORD.

While driving 85 miles from home my 2000 V-10 Excursion w only 92,000K miles on it blew the #3 plug clear out of the head!

The Dealer I called told me they repair this problem once a month. That is a lot for one dealership. There are thousands in

this world dealing with the same problem. Since then, I have researched this and FOUND that not only has it happened to

others, BUT it has happened to ALOT of others...!! I have also found that this problem has been reported many times and to

date, NOTHING has been done about it. When this plug blow out of the head, fuel was being pushed out of the head and could have CAUSED a fire under the hood. At speeds on interstates as high as they are, My infant son, myself and our dog COULD HAVE BEEN KILLED..!!!! So why is no one doing anything about this problem...!!!?????!!!!"

This is the 2nd time a spark plug has ejected from the head. The first time I was lucky and some threading was still left. I was able to purchase a new plug and install it. This time, however, the threading was was stripped when the plug ejected. This is a different spark plug than the first time. I am taking it in today and getting an estimate. I am pissed to find out that this is common malfunction. Just to add to the above complaint, the ball joints have been replaced 3 times in the front end. I am by no means an aggressive driver. This vehicle should be able to with stand normal driving circumstances with no problem. But as I can see from other complaints....
