All 3 happened while driving on highways and in cold weather putting occupants at risk. #1, #3 and #7 spark plugs have blown out over a period of 15 months, destroying the coil in the process. All were the originally installed spark plugs from the Ford assembly plant. Reading and talking with other former and current mechanics, it is definitely a Ford design flaw and Ford should be held liable for repair/replacement, reimbursement and lifetime warranty or until the vehicle is junked.

We were waiting in line to go through santa's magical kingdom last weekend when one of the spark plugs shot off. Completely off. The coil pack was damaged and we were told it would need to be rethreaded.

The vehicle will randomly shut off at any speed, under any condition. Engine dies unexpectedly at highway speeds creating a panic to get out of the roadway. Power to steering and brakes are gone when the engine dies. Vehicle will restart after a couple minutes. The faulty part is the fuel pump relay. It is integral to the fuse box and cannot be changed without changing the entire fuse box. The fuse box is only available from a Ford dealer for $485.20 parts only.

In the last month and a half I have been driving down the freeway at 65mph and blown 2 plugs out of the engiene. This is getting a little costly.

My Ford Expedition is equipped with a 5.4L Triton engine and like many other engines of the same family, it blew a spark plug out of the head while driving down the interstate. This allowed fuel to escape and almost created a fire under the hood. Luckily, I was able to contain it without any damage. However, I am mechanically savvy, so others may not know what to do in such an event. However, the reason is because the spark plug came out of the engine without assistance and being that I have never installed spark plugs in it, the failure was not due to my negligence. Being that this has happened to many other people and the nature of it being potentially fatal, I do not understand why this has not been addressed and considered for a recall to remedy this issue.

Spark plug ejection! I just experienced a problem with my Ford Triton motor where the spark plug will eject from the aluminum cylinder head. I have a 2003 Ford Expedition that experienced this on Saturday. I was driving home from wal-mart with my family in the truck, we turned a corner and my heart stopped! it sounded like I was involved in machine gun fire. I pulled over immediately and my looked. Couldn't initially see anything. My husband checked under the truck thinking it was exhaust related. We were luckily 2 blocks from home, so we were able to get it home and into the driveway. My husband began trying to diagnose the problem and I took to the internet. He took the engine cover off and discovered the spark plug missing and the coil wire broken off and sparking. Long story short it seems that we have experienced the situation where the cylinder head has stripped on the one spark plug. We have begun looking into ways to fix the situation, but it seems Ford has not deemed this to be an issue. Truly don't understand how so many people can report the exact same happenings and no one will do anything about it..... merry stinkin christmas!!! we are reaching out to our local Ford dealer but am pretty sure they are going to tell us we are crap out of luck and will fall on us to repair if we choose.

The contact owns a 2003 Ford Expedition. While driving at an unknown speed, the vehicle stalled without warning. The vehicle was able to be restarted; however, the failure recurred several times. After inspecting the vehicle, the contact noticed that one of the fuse relays was melting into the fuse box. As a result, the fuse box and the power control module relay needed to be replaced. The manufacturer was not made aware of the failure. The VIN and failure mileage were unknown.

We were driving with the kids headed home, going about 45mph and loud noise and smell of fuel, we pull over lifted the hood and saw my coil pack busted off, we drove the rest way home to ark it, and looked again. The spark plug arched inside the head and busted the coil pack bolt and all. Shame that we tried an insert to repair it and doesnt work. I have been stressing this considering im a single mom of two that have disabilities and we have these appointments left and right and its hard walking across town all the time. This problem needs fixed by Ford. I researched and its a known problem cause the cheap aluminum heads. We really need our vehicle...

I was traveling at 70 mph on the interstate. The car popped, sputtered and died. Has steadily gotten more and more frequent. Engine dies at idle, dies at slow speeds as well as faster speeds. Very dangerous! have replaced the PCM, wiring harness, and fuel pump. Is not repaired. Power mirrors readjust themselves when the keyless entry is used. Several warning lights stay on, door ajar, check fuel cap, advatrac will not turn on. Rear window will not work. Back up sensor will not work. Interior lights as well as exterior lighting will not power off when car is turned off. You must manually turn them off or the battery drains.cd player will not eject cd's loud popping sound in the front end and grinding sound when stopping. I have had this in the shop since June of 2014 and they cannot find the problem. Have already spent $1000 trying to repair. This vehicle is dangerous and can very likely cause an accident. It is not safe to drive. Ford auto shop wants to charge me $100 an hour to diagnose the problem then they are not sure if they can find the problem, they are telling me it could cost between $500-$1000 just to find the problem. I have checked several web sites and see that there are many, many people with the same problems with the same type of vehicle. This should be looked into before someone is injured or killed in an accident caused from the car stalling!!!

After accelerating from a stop, a loud bang was heard. What had happened? a spark plug blew out of the aluminum head, taking the threads with it. I was not aware that fuel would continue to blow out of the spark plug hole which could have been ignited by the ignition coil or exhaust manifold. Ford is aware of this issue, but has not recalled the defective aluminum heads, but rather offered a repair kit to fix the stripped threads when this issue occurs. This could have been a very different ending if the fuel would have ignited.
