car   Engine problem 1
Failure Date: 02/05/2011

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 diappointed with Ford, that they have not done anything to resolve this issue, except to keep replacing the coil pack and spark plugs and charging me more money. This problem began in Nov 2007, and I have had to have it serviced for the same issure two other times and now as of today I will have to have it repaired again. I have trust in my dealership that they are fully capable of repairing the vehicle as they have serviced my other vehicles with no other problems.

Ford Expedition 1999 ejected spark plug problem. After having this problem three time already, I start researching about it and seems that 100th of owner of Ford Expedition from 1997 to 2003 are having a recurring problem. Why is not a recall on this when hundreds of owners are spending from $300 to $700 on repairs that Ford should be responsible. It is noticeable that its a manufacture problem not a customer problem.

car   Engine problem 5
Failure Date: 07/07/2010

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.

car   Engine problem 6
Failure Date: 11/07/2008

Driving home from work, I heard what sounded like a gun shot coming from under my hood. Come to find out it was the #3 spark plug being blown out causing damage to the coil. I took the car to the Ford garage and they gave me 3 options. 1. Heli coil it, but they will not guarantee the work and that will be $600. 2. Buy a new head, that will cost $3000. 00 3. Buy a new motor and that will cost $6000. 00 I feel that I'm getting the short end of the stick. This is a common problem with the 5. 4l trition engines and from what I gather this is a very dangerous defect. Someone needs to protect the people.

- the contact owns a 1999 Ford Expedition. He was having problems with the aluminum head spark plugs, the number 3 & 4 cylinder failed, and the mechanic told him it was a design flaw. The failure was caused by not having enough thread in the aluminum spark plug head. He needed a new engine or a head job. It will cost him over $3000. He stated that there was a service bulletin for this problem. The current and failure mileage were both 110,000.


 
car   Engine problem 10
Failure Date: 09/01/2006

I was driving on a busy road with my three children during rush hour. I heard a loud pop followed by the what sounded like machine gun fire. I immediately pulled over to the side of the road and shut down the vehicle. I was fearful of the safety of my children and had them leave the car. I then had the vehicle towed. A Ford repairman looked at the car and stated that the #3 passenger side spark plug blew out. He stated that this a known problem and Ford refuses to acknowledge the issue. He said that they see many of these each week and that it is usually the #3 spark plug on the passenger side. He stated that it would be $2500-$5000 to repair the vehicle. We were told by another Ford dealer that he could fix it for $300-$500. We had the vehicle towed there and despite informing him which spark plug it was, upon inspecting the vehicle he claimed it would be difficult to repair and increased the repair price to $2100. When we objected he offered to purchase the vehicle for $200-$300. We feel as if the Ford dealers are using this issue to run a bate and switch. We have investigated the matter on the internet and have found many others complaining of the same issue and Ford's failure to take responsibility. Someone is going to get injured if they fail to correct their design defect.

On August 2, 2006, while traveling in michigan, a spark plug suddenly blew out of my 1999 Ford Expedition. There was no prior warning or indication of any problem. I had to have it towed to bay city, mi, where a Ford dealer told me that it would cost approx. $3500 to repair the problem. He said it was a recurring problem with Ford Expeditions. My car had approximately 120000 miles on it at the time. I kept the spark plug and coil attachment, and it doesn't look like the grooves on the plug gave way or were stripped.

Failure Date: 06/08/2006

In Feb of 2005 my 1999 Ford Expedition with the 5. 4 v-8 blew the passenger side 3rd spark plug right out of the head. The car had apox. 95,000 miles on it and Ford said warranty would not cover it. It would take 3,500 $ to fix. So I towed it away from grass vallley Ford, a decided to have a mecanic fup a heli coil. That lasted little over a year and in June of 2006 the same plug shot out. I think this is Fords problem and needs to be dealed with.

Failure Date: 04/12/2006

I had just left a stop light when I heard a loud pop. It sounded like something blew up! the car was really loud and ran rough after that. I had it towed to the shop. They said we blew a spark plug and stripped the threads that hold it in place. At a cost of $1,600 to repair we are having a friend look at it. He thinks he might be able to order a kit called timesert to possibly fix it. I hope it works because it will save us a great deal of money. After investigating the problem online, it definitely is a big problem for Ford. They must issue a recall immediately.

I am a school teacher that drives a 1999 Expedition v8. I was on my way to school two weeks ago and heard a loud bang come from under my hood. It then started to sound like a john deer tractor. I had my spark plugs replaced last year and thought that it would be the same again. I took it to the same mechanic that replaced spark plugs last year and told me that the plug blew my thread out and that it might need some serious engine repairs because of it. He also told me that this is a common problem with these Ford vehicles. Apparently it is going to cost me 3,000 to fix. I am a teacher and find it ridiculous to have to pay for this when there has been so many complaints over the same engineering problem! Ford needs to do something about this. After seeing so many complaints online, it really makes me upset and feel emotional stress. The need to recall these aluminum engines.

Failure Date: 12/24/2005

Pulling out from a stop sign in neighborhood when suddenly smoke smell and loud rhythmic banging from under hood. I immediately pulled over and had the vehicle towed to shop. They discovered a spark plug had blown through the head, requiring a head replacement. Subsequently I discovered this is a problem with Ford vehicles with the triton engine-design defect in that their are only 5-6 threads holding spark plugs in leaving them susceptible to this type of failure during normal operation. Ford would not assist me with repairs stating there was no recall dealing with this issue.

Failure Date: 12/24/2005

1999 Ford Expedition - blow spark plug out of number 3 cylinder. Result is loss of power and very poor drivability at low speeds. Also, gas smell from leading injector in now open cylinder. Fortunately I was not towing when the plug blew, or the loss of power could have resulted in an unsafe situation. Ford dealer recommends replacing the cyl. Head ($3,000), doesn't acknowledge any defect that Ford has authorized. Several other mechanics indicate this is a common problem on this engine, deals with insufficient number of threads to hold the plug in the aluminum head.
