The contact owns a 1999 Ford F-150. While the contact's daughter was driving 70 mph, the vehicle made a loud noise and began sputtering. The driver noticed flames under the hood. A passerby extinguished the fire. The fire department was not contacted. There were no injuries. The vehicle was taken to an independent mechanic where it was diagnosed that a spark plug had been blown out of the cylinder head, igniting a fire. The mechanic also noted that the spark plug boot had melted. The vehicle was not repaired. The manufacturer was not made aware of the failure. A dealer was not contacted. The approximate failure mileage was 160,000.

My 1999 F150 truck has a head gasket problem and heater core issue. Started smelling anti freeze on Sunday. Took to a mechanic on Monday and said there is an oil leak, seepage coming from head gasket. The heater core needs replaced, but why oil leak is happening not sure. Was told it would be about $3500 to repair only head gasket and heater core. This truck only has 127,00 miles on it and all regular maintenance has been done timely. Researched this on internet and found many complaints about this same problem. There was even an article in automotive news on 4/1/2002 regarding this issue, and according to written article Ford was fixing the problem for consumers. I called Ford and they told me no. This is a huge expense, and with this many complaints and article that says Ford is aware of this defect and no one can help. Pretty much either fix the head gaskets and hope it works, or was told new engine needed. If this is an issue, and can cause the engine to stop would like to know if I have any recourse in getting Ford to fix the problem. Cannot be driven now because of possible extreme overheating and then engine failure. Any help would be appreciated.

That it looked like it started under the hood. The truck had been driven to the store the morning before the fire, and was parked at the time of the fire.

Thru manufacturer defect (which Ford is aware of) a headgasket seal may fail in their Triton engines due to defective manufacturing and quality control.. said failure of gasket constitutes (due to location of failure) a significant risk of fire caused by exhaust system which is in close proximity

I was cruising along the highway at approx. 68 mph, then I heard a loud pop. Then immediately after sounded like I was driving without an exhaust manifold almost. Once I felt that I had lost a lot of power I then realized what happened. I was luckily 2 miles away from a town and babied it into a store parking lot. Upon looking under the hood I found the sparkplug ejected from cylinder #3 and busted the ignition coil. Now what if I was int the middle of nowhere with my wife and daughter" worse yet what if the vehicle had caught on fire with them as well" due to fuel vapor spitting out the sparkplug bore and getting ignited from the loose ignition coil. I myself and others have been fortunate that these things did not happen, but I can't say for everyone. This is a very big issue that has been ignored and is a potentially huge safety hazard as well.

When backing up after my F150 has been sitting about 2 days I have no brakes unless I rev up the engine for about 20 sec to build up pressure in the electric vacuum brake booster. Have almost hit my wife's car if I forget to let it sit to build up pressure. I have contacted my Ford dealer and they won't do anything about it because I am past the warranty. I am going to have to replace it myself because this is unsafe condition and Ford won't repair it. Also my truck loses power sometimes when accelerating and Ford stated that the turbo chargers are sometimes sucking in water that shuts down one side of the engine to prevent damage to the turbo chargers. There fix is to put a shield or longer tube on it to prevent this. Again because it is over the warranty period they won't do anything. Very disappointed in my F-150 3.5 ecoboost and won't be buying another one.

This is the third time the engine has blown out a plug. I do not know the dates of the other two times, my mechanic can probably look them up. This is obviously a huge problem that many people have. I have paid about $1200 to have the three blown spark plugs fixed. Since this is an inherent problem with Ford engines I feel they should reimburse all costumers, this should not be happening. I am just waiting for the next one to go, when I hear the familiar sound, call my mechanic and lose a few more hundred dollars. Come on Ford, do the right thing!

Traveling at highway speed, the spark plug was blown from the head. The engine spewed fuel out of the hole and I thought a fire might occur at any second. Many people have had this exact problem with this engine and many more will. This occurs because the head is aluminum and the spark plugs are steel and only thread in to 3 or 4 threads. Terrible design flaw.
