I own a 1999 Ford Expedition, last year the number 3 plug popped and had to be rethreaded and now we have a different popped plug that needs repair. The first repair cost $800 and I had to rent a car. For this second repair I brought the truck to two repair garages and neither mechanic could repair this plug because it could not be reached. How can I be compensated due to this being a known problem and a second occurrence in my vehicle?

First incident, I was sitting at a red light and when it changed I hit the gas and the spark blew out of the second hole on the passenger side. Second incident, I was driving down the road at 60 miles per hr and the plug in hole 3 on the drivers side blew out. Third incident, I was at stop sign, and when I hit the gas to go it blew the spark plug in hole 3 on the passenger side almost causing an accident. This was all in a 5 month timeframe. The repairs were made using the timesert kit from timesert.com. The mechanic charged me $350 + parts.

1. normal driving conditions, and normal operation of the SUV. 2. sudden noise from the engine, upon inspection we found that the spark plug had been ejected from the engine block and striped the threads. 3. modification kit (readily available, as the parts store said this is a very common problem) was purchased and installed.

I have a 1999 Ford Expedition, Triton V8 engine, it has 100,000 miles, I have taken very good care of this car. Change the oil every 3000 and ect. About 6 months ago my spark plug shot out causing severe damage, it cost me $460. 2 days ago I was coming home on the expressway when another shot out causing me to go from 60miles to 40 where I almost got hit by a truck! what is going on" I'm told that this has been happening for years. How can there not of been a recall on this engine defect. And now im out $500 again and my worry is I still have 6 more plugs to go, the mechanics have to get a special repair kit from Ford. I am so upset, this is not fair that Ford will not recall this engine and either repair the defects or pony up a new engine? but they will pay 12months of a car payment if you buy a new car and lose your job????? something has to be done about this. I could of been killed by that truck from slowing down so fast. Thank god I was in the right lane. Any suggestions" it's only 10 years old and in excellent condition!

I have a 1999 Ford Expedition eddie bauer with a Triton 5.4 liter V-8 and this is the second time that I have had a spark plug blow out of the cylinder head.. I am aware that this is a re-occurring problem with the Ford engine, but I like many others am getting tired of shelling out thousands F dollars to fix a "design defect" I am a laid off auto worker living in Michigan and I cannot believe that Ford wants us to still buy their mistakes and then bail them and the other manufacturing companies out of what is clearly there own doing.. and as far as my truck I think will be looking into a better kind of car and company!!!!!!

Driving home from doctor visit, heard a loud pop, and lost power, very loud engine noise as if I had no exhaust. Mechanic looked at it apparently the engine blew out a spark plug making it necessary to replace the cylinder head since it stepped the treads. And also broke the coil. Am on disability and fixed income, the repair cost is so high I have to wait and be without a car. Do not know what to do. The mechanic told me it is a common problem with this vehicle and Ford. And I researched the web and found out that many others experienced the same thing. Furthermore when going to Ford for repair, they say that the new head is a improved version. So if it is an "improved" version that mean that they know that there is a problem with the product to begin with. Ford should replace the faulty heads at no cost to vehicle owner.

I own a 1999 Ford Expedition and my family has experienced (3) blown spark plugs! the Triton engines Ford makes have aluminum heads and spark plugs are blowing out. On May 6, 2008 was my first experience (cost $273.03) replaced helie coil. July 18th 2nd blowout with 3 young children late at night. Police officer has had 2 blown spark plugs on his Ford! (cost $1,502.02) had to remove head. #3 blowout last night pulling into my driveway with family on board. I will not take this vehicle anywhere again as these explosions can cause a car fire and I will not risk that or being stranded in remote camping area. I have wrote a letter to Ford board of directors- called Ford directly and at this time there is "no customer satisfaction programs" according to "amy" my case girl. Google "Ford Triton engine blown spark plugs" and you will see the many consumers frustrated and experiencing this. If my car catches fire and my family is injured or killed I will hold you and Ford personally liable as this is my written notification of this defect. There needs to be a recall and it needs to happen now!

97 to 99 5.4 Ford like to blow plugs out of the cast aluminum cylinder heads. They doubled the threads in 2000. It occurred to my 99 Expedition, out of warranty don't expectancy help from Ford maybe your dealer. My Expedition was 4 years old, at the time. Best advice buy GM forget about Ford unless you own a tow truck.

My wife was driving to Colorado springs on hwy 24. She pulled away from a stoplight when she heard a loud slapping noise. She was able to get to the side of the road safely, despite heavy traffic. We had the Ford Expedition towed to the dealer we bought it from. They have called me to tell me the number 7 spark plug blew out of he block ruining the threads that hold it, in addition the coil pack was ruined. I have a warranty on this vehicle (it was bought used), the service manager is telling me they will not cover this under the warranty because it is a "maintenance issue". I informed him that I will not pay for this repair and he said he would call Ford to see what they are doing, lol. If my wife had been traveling at hwy speeds she could have crashed and the possibility of a fire was real because of the fact fuel was coming out of the spark plug hole and the coil pack was still firing. Something must be done.
