One of the spark plugs on my 1999 Ford F-150 simply blew out of the head while driving at a mere 15 mph. After inspection, that plug was ejected clear of the vehicle, never to be found, along with all of the threads that it was screwed into.

1999 Ford F150. Ford put aluminum heads in these vehicles. They found out that they were shooting out the spark plugs. They have never recalled this. In the past 4mos, we have had 4 spark plugs shoot out. Each time this happened, it cost $300 to repair and $200 for towing. Not including the money lost in wages, renting a vehicle etc. I contacted Ford and filed a complaint. They said they would document this and that was pretty much the end of this. The dealer ship we took this to, said they see a lot of these. It was because of the aluminum heads and Ford recognizes this now and changed it. Well, they did not change it for the people who still have these trucks. This situation if very frustrating to me as a consumer. This could possibly blow the entire engine. This vehicle is not even 10yrs old. There are 4 more spark plugs that could go yet. We do not have the extra money to keep sticking into this truck and we are in no financial situation to buy another one at this point. We have to get by with what we have, but we should not have to be dealing with this mess. In my opinion and others with the same complaint, Ford should recall this. They need to make this right to their consumers. Thank you, william krumhus

Had just pulled out from intersection onto main road when truck developed a severe misfire. I pulled over immediately and upon inspection found the third spark plug on the right side had blown out of the hole. We took it to a garage less than a block away and they were able to install a new plug and coil pack but some of the threads in the head had been damaged. We were told they didn't know how long it would hold. Old parts are not available. I understand this is a problem on the Ford Triton engines and think a recall should be issued.thank you

The contact owns a 1999 Ford F150. In between oil changes, the head gasket leaks oil onto the motor and causes it to smoke. As a result, oil gets beneath the motor and into the exhaust, which could cause a fire. The vehicle is also smoking. The Ford dealer recommended that the contact keep the vehicle parked. NHTSA campaign id number 98V194000 (fuel system, gasoline:fuel injection system) was referenced. The current mileage was 135,000 and failure mileage was less than 100,000.

I have a 1999 Ford F-150, 5.4L V-8 Triton. It has spit the number eight spark plug twice, and now the number seven plug has been ejected multiple times. Luckily, my wife and kids weren't with me when these events happened. After the first time, and much reading and research, and the fact that your office will not get involved with this well documented problem, I do not feel safe with them in my truck. It's only a matter of time, if it hasn't happened already, the coil pack or spark plug will be ejected right into the fuel rail and the coil pack will still be sparking and cause a fire. I really appreciate yours and Ford help with this, as I am a disabled vet on a fixed income and can't afford to fix it this time; so my truck has been sitting in my driveway for over two months. Maybe some day someone will realize the dangers here and help us!

Blew out sparkplugs and broke bracket on the side of coil packs. Don't like paying $85 a pop for Ford's poor design. Plus the healy coils or maybe that's the motive. This happened three different times.

My daughter was traveling on a high speed state highway when a spark plug blew out of the aluminum cylinder head of the 5.4 liter engine of her 99 Ford F-150 XLT 4WD pickup. The truck was towed home. After numerous inquiries with Ford customer relations I was rudely instructed not to contact them further. Her truck had 65,909 miles on it. I had it towed to the local Ford dealer and paid them $3600 for the repairs and a new head assembly. I'm a retired auto technician with 50 years in the business, so, I consider myself knowledgeable. I know of 5 incidents with our customers suffering the same fate. One customer had a truck still under warranty that blew all 8 plugs out. All customers affected were towed to Ford dealers by us. This condition could present a nasty accident on a super hi-way with possible loss of life.
