2002 F150 harley davidson edition with only 75,000 miles blew a spark plug out of the head. Ford admits no culpability even though they have tsb's. estimate to repair plug & change out other 7 spark plugs with 8 new coils was $2800. I could almost purchase a new engine for that. Found a reputable garage to do the work for around $900 total. Understand that I should get used to this happening until all 8 spark plug holes have been repaired. Ford man for 35 years. Own 3 currently. If dependability is no longer a priority for Ford don't know what I will do.

While driving my vehicle under very normal circumstances, traveling approximately 30mph, my truck began to run very rough and there were loud popping noises coming from the top of the passenger side valve cover. It turned out to be a blown-out spark plug and coil pack.

Engine quits running and wont restart, so you have no power steering or brakes. Problem indicators are 1. engine wont restart/ or quit running 2. odometer reads all dashes, no numbers,3. anti theft activated. This is caused by the power wire in the fuse box under the hood corroding off for the PCM relay and leaving the PCM dead.

On March 22, 2014, the truck was parked in a local parking lot, the ignition key was removed and the truck was locked. The driver returned to the truck to find that while it was parked, a fire had begun in the engine compartment of the truck, and the fire department and police department were on the scene putting out the fire. Because of the quick actions of an individual parked nearby who used a fire hose to contain the fire until the fire department arrived, the cabin and the body of the truck were spared, and the damage was localized to the engine compartment. The cause of the fire was the speed control deactivation switch.

Spark plug failure as accelerating from a stop light, and engine problem resulting from 7 cylinder operation. Got it to a mechanic and he was able to sleeve the spark plug thread and install a new plug. Now the same is starting again. I am taking the vehicle to the mechanic to make permanent repairs for all the spark plug. This may end up with the engine heads being removed in order to make complete repairs, and the cost for that will be thousands of dollars. This is a Ford engine design problem that Ford has been aware of, yet they continue to deny any responsibility.

A spark plug ejected from the right side head of the engine head while running down the hwy at 60 mph. The head might be damaged. I haven't had a chance to get it fixed. Been a Ford truck guy all my life & I can't believe Ford hasn't accepted any responsibility of any portion or kind for this. My estimated expense to repair this is $1,000 to $3,000 depending on any damage to the head etc.. I paid $4200 for the truck in April of 2013...it is in very good condition & to good to junk in my opinion. Besides I can't afford to buy another truck so I have to try to fix it. This is beyond disappointing, it is a major blow to the budget etc. Etc. Etc......

I was driving about 60 mph on a county road when the number 3 spark plug blew out of the cylinder head. I was able to stop safely, but the incident scared my 5 year old daughter. Because of the plug blowing out me and my daughter were stuck on the side of the road for about an hour in the Florida sun waiting on someone to come and get us and the truck. I called around and several repair shops stated it would cost me between $700 and a $1000. After doing extensive research online I discovered this is a major problem for the 5.4 Triton engine. I called Ford and they said the repair cost would be on me to fix. I feel that there needs to be a recall because of this defect in the cylinder head.
