I just purchased this Expedition and the number 2 spark plug ejected from the engine destroying the coil pack and stripping the threads. I have read alot about this and feel that Ford should do something on this issue. So many people have spent so much money on a design failure that Ford does not want to take responsibility for. I have owned numerous Ford and I am very disappointed in this vehicle. Since I just got it I hope this don't happen again. It should be recalled.

While moving across country my 1999 Ford Expedition ejected the number 3 spark plug. This situation placed my family in harm's way as it occurred on the interstate and was quite startling. The service rep was able to tell me what was wrong with my vehicle as soon as told him the make and model. The repair cost is significant, but the potential for an under hood fire caused by the fuel vapors being ignited by the ejected plug is of grave concern. Ford is keenly aware of the problem and has designed a replacement head for the vehicle, but refuses to do the honorable thing and replace it at their expense. They instead choose to profit from their customers by charging them for the repair or replacement of the cylinder heads. I find it predatorial that a car company would make a faulty product and then profit from the repair of said product. This could start a new precedent by signaling to other car companies that if you sell a defective vehicle, you can make money on the backside by charging for the repair or replacement of that part. The safety concerns that are associated with this failure are related to the loud and sudden popping sound when the plug ejects, this could easily distract a driver and could potentially lead to a fatal accident. The fuel vapors could be ignited shortly after the plug ejects and could also cause the driver to lose control of the vehicle. Considering the Expedition carries up to 9 people the risk of a traffic fatality is increased greatly. Please hold Ford accountable for their error and lets hope no one gets hurt or killed until then.

I own a 1999 eddie bauer Expedition. Was at a light and turned right going about 20 miles and hour when I heard an exaggerated pop and it seemed like it rattled very loudly. This is the third time spark #3 has popped out. This is ridiculous. Worst part is that it happened at 2:00 am on a dark road. Had to get it towed to a local mechanic.

For the 2nd time I have had a spark plug blow out of the engine. This time the gas caught fire. I managed to beat it out with my jacket, unhook the fuel injector, and drive the vehicle the rest of the way home. Fortunately the fire started just as I opened the hood and I got it out before any damage could occur.

A spark plug blew/popped out the head on our 1999 Ford Expedition, causing fuel vapor to leak out of the opening, and starting a small fire, which was quickly doused. This is the 2nd time in 3 years that this has occurred, resulting in over $2000 in repair costs for each occurrence. I am very frustrated as I have read thousands of complaints from other Expedition, Navigator, F-150, and F-250 owners with this same dangerous situation, and nothing has been done" peoples lives could be at risk with this issue" recall now!

- Hayward, CA, USA

My 1999 Ford Expedition blew a sparkplug. The cost to fix is ridiculous compared to the worth of my SUV now. I checked online and this apparently happens all the time to this engine yet there has been no recall. What is up with this" this is dangerous and costly. If brakes for Japanese carmakers are recalled why not plug problems which can create engine fires and strand people far from home? please help"

1999 Expedition 5.4L blowing spark plug from cylinder head.

- Manhattan, IL, USA

My 1999 Ford Expedition had a spark plug shoot out from the head on my way to my cabin April 2nd, 2010. I have 2 small children and was driving in a area with no cell coverage or gas stations. The fumes made the inside of my vehicle smell horrible and had to drive to 17 miles with the windows down late at night. This is a bad engine from Ford, I could've been worse off with kids getting sick from gas fumes or being stranded in the middle of nowhere.

Normal daily driving. Spark plug blow out. Not replaced yet.

- Gray , KY, USA

This is the second time I've had a spark plug eject from the cylinder head due to the poor threading in the cylinder head! it cost me $3,000 for the first fix, and now maybe another $3,000!!! this was the second one to have done this in a 3 year span, it damaged the cylinder head and ignition coil along with damaging my fuel rail. The first time this had happened we had to take it into the shop and have the entire cylinder head replaced along with ignition coil gaskets ect. The bill was $3,220.

My son exited the publix grocery store where he was working and found that our 1999 Ford Expedition was on fire with no one in the vehicle with the keys in his pocket. The flames were coming from the engine department. Four small fire extinguishers were not able to extinguish the fire, the fire department was called. The vehicle was destroyed, as well as damage to the two vehicles parked on either side. We were having no mechanical trouble with the vehicle at all, in fact, we had just replaced the four tires the day before. There was a recall on the vehicle regarding the cruise control, which we had complied with by immediately taking the vehicle to our local Ford dealership for the recall, where it was taken care of. Supposedly the problem of unexpected fires was corrected. Fortunately there were no injuries or fatalities that occurred as a result of this incident. Thank goodness the vehicle was not parked in our garage when this fire occurred. It has caused us a great deal of unneeded aggravation, time and unavailable costs involved in accommodating our son's responsibility to get to and from work, along with our own responsibilities.

This complaint is in reference to our 1999 Ford Expedition. My wife started out on her daily drive to work. As usual, she allowed the vehicle to warm up for 10 minutes before leaving. About 1 block from our home, she heard a pop and the vehicle started to shake, run rough, rattled and lose power. She also had trouble steering the vehicle because of the loss in power. She was able to return home without any further incident. I inspected the vehicle later in the day and found that the 2nd spark plug from the front of the engine on the passenger side had blown out of the head and damaged the coil. I am reporting this incident because I have read of many Ford owners who have experienced this same failure. This vehicle received a tune-up at approximately 92000 mile in 2006. It currently has around 130000 miles.

While sitting in traffic in downtown cincinnati, I heard a loud "pop" under my hood and then my truck sounded like a steam engine. I also began to smell raw gasoline. I pulled to the curb and checked under the hood. Drivers side rear spark plug had blown out, breaking off the coil pack. Gas had sprayed onto the side of my engine. Mechanic advised that it was a common problem with this engine. Manufactured with as few as 4 threads to hold in a spark plug. Thin walled aluminum cylinder heads are a very poor design. Ford advised that they were aware of the problem, but had no intentions of a recall.
