While driving down the road the threads in the right rear cylinder head of my 2006 ford f150 5.4l triton v8 failed causing spark plug ejection and coil damage. It is currently being towed to the repair shop and, according to the dealership, the whole cylinder head will have to be replaced. It is unknown, at this time, what the dealership will cover and what my expenses will be.

What a shocker, I go to the ford dealer for the 100k tune up for my f-150 king ranch original cost $450. Almost two weeks later, truck still isn't finished cost is at $3, 500 still can go. They don't know yet until their finished putting everything back together. 7 of the 8 plugs broke, two would not come out. Finally, they got one of the two out. The one is seized up pretty good. The had to take the head off and waiting on the outcome. I'm up in arms on what to do. I don't have an extra $3, 000 laying around to pay for this plus the price can still go up. How can they not tell you this up front and keep padding the price and not knowing what its going to cost until you pick your vehicle up. Please contact me, I would like to file a suit against ford but need assistance. I talked to someone from fords front office about this issue. They are well aware of this matter. All they say is that its not under warranty and my vehicle is over the 100k max. Come to find out, no matter what warranty you have, this particular issue has no warranty to begin with. All they would do is offer me the "x plan" on a new vehicle. Now, why would I want to buy a new vehicle. I've been raised on ford vehicles my entire life. I must say this will be my last ford truck for sure. A friend of mine has a toyota truck and has over 200k miles. Never has had a issue with anything. Please advise on what to do, this needs to stop and ford needs to do something about this. But I have a feeling they won't or they would of done it already.

I have a 2006 f-150 with 99,000 miles. The engine developed a miss when under heavy load. Checking the scheduled maintenance recommend by ford, the spark plugs need to be changed at 100,000 miles. I tried to change the plugs myself and broke the first one. I stopped at that point and had it towed to the dealer. They broke five additional plugs and the vehicle was down over night. Ford has issued technical service bulletins on changing the spark plugs. This is a known issue to ford. When I contacted ford they said there was nothing they can due since its out of warranty. I was stuck with a $300 labor bill which did not include $75 for spark plugs and $98 for the tow. Ford needs to be held accountable for there engineering mistake.

I have a 2006 f150 with the 5.4 engine. I have never replaced the spark plugs and the truck has 144k miles. I am now stuck with ~$1800 to pull the cab to get to the heads to get the plugs out. 2 mechanics cannot get it out normally. I am told that a fix for stripping the heads is with a sleave that I cannot get out of cylinder #8. I was never informed to have the plugs changed at 80kto 100k miles. I would not have known anything about this. I think the fix is a poor design and I was designed to cover another plug issue. I am wondering why 2 wrongs do not make a right and I am wondering what recourse I have. I have purchased or traded 3 new trucks and currently drive a mustang, all purchased in the last 4 years. I am seriously wondering if I should ever buy another ford truck at this time. I have been more than loyal to ford products over the years.

My vehicle is showing extreme hesitation in acceleration when entering a highway or passing another vehicle. During these processes, my vehicle will start backfiring and missing. The "check engine" light comes on at this time. I took my vehicle to two different state licensed mechanics, and chapman ford dealership in philadelphia. All three told me the plugs should have lasted 100,000 miles or better and that they have had problems with the design of the engine and these plugs are very complicated to replace. Special tools would be needed to replace them. They also said it is very common these plugs would break off when being removed. The cost to replace the plugs would be approximately $400 to $550, with an additional cost if any plugs break. The dealership told me there is no recall when there should be. This is a major problem at the expense of the owner, as well as a safety issue. I realize spark plugs are not under warranty, but the cost to replace them is ridiculous because as the mechanics stated, it was a flaw in the design of the plugs and they corrode to the engine block. Ford realized this and changed the plugs in newer vehicles to a non-corrosive plug. I feel the customer should not have to pay for a poor design from ford. I am scheduled to have this work completed on july 21, 2010 at chapman ford in philadelphia because my vehicle is unsafe to continue driving on the highway and is using an access amount of gasoline.

Certain ford makes, models and motors are known for ejecting spark plugs which destroys the ignition coil and is a fire hazard. They are also known for the spark plug breaking while trying to remove them which is a financial burden on the customer as well as a risk the motor while trying to resolve the issue. There are tsb's on this. I never received a letter from ford to give me the heads up on this and learned after the fact of attempting to get a tune up.........now stuck with two broken spark plugs stuck in the motor and have no idea how much this is going to cost me in the end. I am without my truck while we wait for a tool that will hopefully remove the broke off sleeves. If it doesn't work I will have to have the head pulled and who knows if it will need to be replaced. Even if it removes it, I won't know until something happens if it ends up causing damage to my engine. I have had bad experiences with ford - two vehicles now. They do not back up their known defects. My first problem with this f150 (triton) was when the computer shut down leaving me stranded in another state because the wires were rubbing against the steering column bracket. I put a lot of miles on so it was in extended warranty and the deductible paid the repair. Ford had no intention of taking responsibility for it even though it would have normally been under original warranty except for the miles I put on a vehicle. There was no roadside service in the area I was in and I got stuck with all kinds of expenses from it. Seems our american manufacturers should be held accountable for their multiple known defects as well as our foreign manufacturers. I am only answering yes to the fire because I am aware that others have had this as a problem. I have not had a fire yet, but we are not done trying to resolve the problem.

During routine maintenance spark plug change six of the oem installed sparkplugs broke off in the cylinder head of the engine. Ford dealer admits to having problems with this design engine and states this occurs often. Ford dealer stated that ford admits an issue with this design sparkplug and has a tsb detailing the procedure for broken plug removal but has issued no formal recall. Dealer advised that ford also has a "special tool" designed for this 5.4 3 valve series motor that is engine specific to remove the broken piece of the sparkplug because this happens so often. All but one of the broken plugs was able to be removed using a specialty tool purchased at an automotive parts store. Ford dealer was unable to get the last broken plug extracted from cylinder head with their "special tool". Engine needed to be dissembled and cylinder head removed so that the broken piece could be extracted. This repair cost $1708.00 to complete. Along with $85.00 diagnostic fee to tell me they could not get the broken piece out. The repair took two weeks to have completed. I feel that ford should issue a recall for this issue and they should reimburse me for my costs due to their faulty design flaw.

My 2006 ford f-150 had a spark plug broke off and now the only way to fix this is to remove the head approx 3000.00 to correct. Ford says they are aware of the problem but they refuse to do anything about it. The vehicle only has 45,000 miles and the truck is now non drivable. Why aren't they being held accountable for something when they know it is a problem with this style vehicle.

My 2006 f-150 with the 4.6l motor ejected a spark plug from the cylinder without warning. I went to crank the vehicle on 2/19/10, and there was a horrendous knocking or tapping sound. I was on my way out of town, so I did not have time to do a thorough check of what could be wrong. I shut the vehicle off and left it sitting until I returned on 2/21/2010. Upon looking, I noticed that the second cylinder in from the firewall on the passenger side had ejected the plug from the cylinder well. When I went to try to put the plug back in, it would not tighten. I jiggled the plug and ratchet extension and noticed that the threaded area to accept the plug was much larger than the stock plug. I understand that ford has used many excuses as to why this happens, but I assure you that I have purchased no new parts. This vehicle is now unusable, and is my primary transportation to and from work. There is obviously an issue with these motors and ejecting plugs, so my question is why has ford not stepped up to address this issue?

I purchased a ford f-150 in 2006. I am at my 100,000 maintenance and the spark plugs have to be changed. I spoke with a representative at the ford repair shop who told me that I would have to bring my truck in 24 hours early to soak the plugs because they will break in the motor and I will have to pay to have them removed. I followed there instructions on monday morning and took the truck to them. They called and informed me that they would have to take the head off my motor to remove the plugs at a considerable expense to me. It does not seem fair to me that if ford mechanics put ford plugs into there ford trucks and when there ford mechanics try to remove the ford plugs from the ford vehicle they break and I have to pay for the damages.

I'm an owner of a 2006 ford f-150 5.4 engine. I have had 3 engine failures with this truck the first one was an injector. Second was a timing solenoid. Third was a coil. I had over 100,000 kms. I had my plugs changed. The mechanic ended up breaking off 6 plugs in the engine. This is a very expensive repair, it should only be regular maintenance. I have done a great deal of research and have found it is a very widespread problem. I feel owners should be compensated. Any advice I can receive would be helpful thanks in advance.

Sparkplug popping out while driving 60 MPH on highway ,thought it was a blow out of my tire had to quickly move over to the right and exit .found out it was the sparkplug . Later after a few phone calls to dealers and mechanics this is a problem that happens regularly and that ford knows about this problem. This should never happen. I feel cheated and I would have never bought this truck f-150 at all if I new about this. After all this I will contact the media and local papers to let people know about this problem. I also found out if will start a fire if I kept driving.

All shops in my city are refusing this engine to work on what to do I'm stranded by the manufacturer to whom I have been a loyal customer.

My 2006 f 150 has shut off twice on me while driving on the freeway. And after barely avoiding the semi behind me I managed to pull off the side of the freeway and turned the key off , after waiting about a minute I turned the key on and the car ran fine for about three months and then it happened again on the freeway.the light comes on to signify that the problem is the electronic throttle control, but I called around a few places and they all say the same thing ,they cant do anything unless the check engine light is on. Does some one have to die in order for ford to fix this problem.. Is it worth losing a life over?

I purchased a ford f150 truck with 65,000 miles from a ford dealer. After monitoring the engine oil over the first 3 months I took it to the ford dealer 2 times for an engine oil consumption test. This truck uses 1 quart of oil per thousand miles being driven. It does not leak oil, it burns it. After contacting my local ford dealer as well as ford motor company, they stated that this is "normal." this is not normal for a 2006 vehicle. In a time when the united states is concerned with global warming, this vehicle is producing emissions that are way out of the ordinary. I will be stuck with a vehicle that cannot pass emissions tests when they become mandatory in this area. If you are not the agency to contact, please refer me to said agency.

He informed that there is an 8 year 80,000 mile federal emissions warranty. I again called richmond ford llc. Spoke with the service manager, he told me that there was no such warranty.

The dealer inserted a helical coil to the head of the cylinder, but it was not a full repair.
