After driving the vehicle approximately 10-12 miles, I parked it in the driveway. About fifteen minutes later my wife and I smelled smoke. When I investigated, I found engine compartment of the truck in flames. The fire appeared to have started on the driver's side of the engine compartment above the front wheel. Fire company was required to extinguish the flames. Everything forward ofthe firewall was destroyed.
My 1999 ford f150 was sitting in the driveway next to the house. Apparently it spontaneously combusted. It is now a burned-out shell of a truck. Fortunately, my wife was working from home and called the fire dept so the house did not suffer much damage. I did lose a few thousand $ worth of tools in the truck.
Tl* the contact owns 1999 ford f150. While driving at 55mph the vehicle shut down without warning. He took the vehicle to the garage. He was informed the motor head sending unit had to be replaced, but the motor head hole was defective because it was drilled too large.the garage was not able to replace the motor head in a timely manner. The total cost for repair was $700.00.the contact contacted the manufacturer. The manufacturer did not offer any assistance . The failure and current mileage was 130,000.
I own a used 1999 ford f-150 5.4l engine. It has approximately 117,500 miles. While driving on the freeway in california yesterday, I heard a loud knocking type noise. I pulled over to the shoulder and with the engine running opened the hood. Just as I did, the spark plug ejected from the cylinder head and came within 3" of my skull almost killing me. Took it right over to the power ford dealer in tustin, ca. They want to charge me a diagnosis fee to tell me what I already know. I told them they better assure me that the remaining 7 plugs won't do the same thing or I may have been killed and a law suit would have been a definite. This is very dangerous and out of warranty so to speak, but it a unique problem all it's own. This has to lead to a recall. It is far to dangerous and in light of what has come up with toyota recently we cannot allow these things , these serious danger to continue to be allowed to save ford a few $. I am also going to write to congress.
Spark plug blowout on 1999 ford f150 with 5.4l triton v8. It seems to be a very common problem with the ford modular engines. Today, I heard a loud pop come from my engine bay as I accelerated and then the sound of what seemed to be a massive exhaust manifold leak. Upon further inspection, I found that the spark plug on the rear passenger side of the engine had ejected and broke the coil with it. I was lucky that it had only damaged the threads on the spark plug and sheared the coil at its mount, instead of damaging the threads on the head, but from reading the multiple other stories online about this happening, it seems that I am luckier than most. I was able to repair it by replacing the spark plug, boot, and coil, but from what I have seen, most people have to replace the head when it happens. I don't see why there has not been a recall since it can cause an accident due to scaring a driver when they hear a loud explosion in the engine when it happens, or possibly killing someone as fuel/air vapors escape the engine and the spark plug could possibly ignite it outside the engine, and being right next to the fuel rail and injectors, possibly cause massive fire damage with its occupants still inside the vehicle. Please tell ford to recall this problem. I see the fix being as simple as putting stronger thread inserts to prevent the spark plugs from ejecting. Its ridiculous us as car owners should have to continuously pay big bucks for a faulty engine design that ford refuses to acknowledge or fix. *jb
Spark plug keeps being blown out of the cylinder head. Now they want to replace the whole head $3,000.00 they first time it happen they just put in a helicoil kit and charged me a $1,000.00. I have also replace 2 coils on this side of the engine and also had to replace the head gasket on that side.
Accelerating on ramp to freeway heard a loud bang, vehicle lost power and engine ran rough while making loud unmuffled noise. Found that vehicle had blown out #6 spark plug. Ford f-150 with 5.4l engine, with 120,000, original owner. Found numerous internet postings on this problem. Contacted manufacturer, no recalls or assistance. Makers fix is to replace heads, at customer expense. Found shop offering in vehicle repair, and expect repairs to be done shortly.
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.
Was driving my ford on the freeway when I heard a loud noise, I stopped nearby took a look at it found the spark plug had been blown out, called ford the said they could fix it for 2200!
On four separate occasions, the vehicle began idling and accelerating roughly for about 2 days. The check engine light would come on after about a day. The problem would stop and the light would go out before I had the chance to take it to a shop. This last time, march 27, 2009 it had been raining for a day or two. I went to start the truck and the engine was idling and accelerating roughly again. Upon taking it to a local repair shop, I was told that the rear two coil packs had failed and that this was a common problem with this model. It was explained to me that the rain run off from the vehicle dripped onto the rear two coil packs and would cause premature failure. The problem started at about 71,000 miles and was repaired at just over 72,000.
Went outside to start my truck 1999 ford f-150 5.4l. As soon as I started the truck I heard a loud banging, shut the truck off, open the hood, and a spark plug had blown out the head ripping all the threads out and breaking the coil. So now my $14000 truck is useless. My only options include $3000 for new heads or a heli coil kit which will eventually allow the same problem or worse to occur.
The number 3 spark plug blew out of my 1999 f150 while pulling away from a stop light. The aluminum head has only 4 threads holding the plug in place, clearly a design defect. I had both heads removed and had all eight holes repaired...total cost was about $3,000. There was 80,000 miles on the truck at the time. Ford should stand behind their product!
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 300.00 to repair and 200.00 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

Tl*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. The federal safety agency 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 fords 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!
My 1999 ford f150 ejected a spark plug - damaging other parts as it ejected - this is a manufacturing defect that needs a recall a fire can easily happen in this situation.
Spark plug blew out and broke boot when this happens it still sprays gas out and could start a fire.then a month laiter it did the same thing with another plug not the same plug as the first time.had to buy a threader kit and new boot and new plugs did it myself it has happen 2 times and will most likely happen again im afraid it will start a fire because it sprays gas out the plug hole and you have a spark plug boot there sending spark to the plug.
My emissions, egr and 02 senors.
1999 ford f150 5.4l v8 blew out the number four (4) spark plug located on the passenger side in the rear. Personal research has told me that this is a very common problem due to a "factory defect" (ford motor company does not admit this) of not having enough threads in the head to hold the plug. Recommended repairs include replacing the head, which is $2,500 job. I am using a thread tapping dye with an insert to fix this problem. It is still not put back together at this time. In my opinion, ford needs to recall the heads on the 5.4l motors for any and all years that have had these blow-out problems.
