Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2002 Ford F150 5.4 liter engine 2 months ago I had a spark plug thread failure on my F150. It cost $400 to repr the vehicle so that it could be driven. 1500 miles later I have another thread failure causing another plug to be spit out of MY6 cylinder head. I have been told by dealerships and mechanics that this is a common problem and that I can replace the heads with new ones but that they can not guarantee that it would not happen again. Or I can have both heads removed and have inserts machined into the heads to prevent anything from failing again. The cost of this process is $2200. I have now spent $2600 on the engine in 2 months time due to a improper manufacturing of the heads that were made for this engine. I would like to see a defect recall made on the heads and possibly be reimbursed for some of the expense.

Vehicle started making loud noise under the hood, turned out to be a stripped spark plug hole in the cylinder head that led to complete replacement of head. Dealership stated this was the 4th one this year, always 2002 model, 5.4 liter engine, always right side cylinder head. If a dealership in a town of less than 600 people has a failure rate this high, how big is this problem nation wide?

I have a 2002 Ford F-150 with 65,000 miles on it. It is the 4.2 liter V-6 that has always been taken care of. The motor threw a rod and needed to be replaced and stopped with a loud banging and the cost was 5,000 for a new long block by local Ford dealership. I have looked on the internet and seen hundreds of folks having to have their same V-6 engine go out prematurely. From 40,000 to 100,000 miles. The plastic intake gaskets are faulty and it gets coolant on the spark plug in cylinder and motor goes out by throwing a rod. Ford does not accept any responsibility for this lemon engine that seems to have many design flaws starting from 1997 when they started putting it in their vehicles. Updated 09/19/07

In the middle of July of 07, my wife, granddaughter and I were coming home from vacation in Idaho, by york, ne. The truck was all of a sudden running rough. I was unable to find a mechanic to let me know what was wrong. I had to drive the vehicle home. I called my son in Idaho, who is a mechanic and he listened to the vehicle over the phone. He told me that it sounded like a spark plug had blown out. I looked and saw the plug on top of the engine. I called around and found out it was going to cost over $2000 for the job. Then I found out that Ford had made a kit for it. In over 40 years of driving I have never heard of such a thing. If Ford made a kit for it, then it seems to me that they should either fix the problem or inform customers about it.

I have a F150 2002 Ford pickup with 55,000 miles on it. My parents and I had just finished lunch and got in my truck. I turned the key and we heard 2 loud popping noises and the motor started running rough (pulsing). Turned the vehicle off, opened the hood only to discover the spark plug had blown out of the #8 hole and was laying down in a crevice on the engine and then rolled out of sight. We had to call a flatbed tow truck and were towed 82 miles back to North country Ford, coon rapids, mn on a Saturday night where we left the vehicle. On Monday morning I found out to my surprise from the service department at North country Ford that the extended warranty I have on the truck would not cover the $2,300 cost. North country sent out the head to have the holes drilled larger for the spark plugs. I have driven Ford products for over 45 years but this will be the last Ford unless Ford owns up to this problem and does a recall and credits people like myself who have been inconvenienced.

I purchased a used 2002 Ford F150 4X4 from the manager of a Ford dealership. Within 7 months a spark plug blew, we did not know it was such a problem but we repaired it and a couple of months later it did it again we repaired it thinking maybe we did not repair the first one correctly. Then a month later it did it again. I searched web sites and saw it was a greater problem. I took my truck into a Ford dealership-(which say they can not really say what the problem is exactly?) it could be from a blown spark plug.. but refuse to give that as a reason" I wonder why" so they have quoted me about $3200 in repairs not including labor, which will take it up to about $5000!!! I can not afford this as it took everything for me to pay for this truck, which I feel was sold to me by the dealership and even the previous owner of the truck that knew of a problem and did not disclose it to me. So my truck will sit until I decide what to do, as I make monthly car and insurance payments on it.

On two occasions within the last year, my Ford F-150 with a Triton 4.6 liter V8 engine has "blown a spark plug" causing a substantial loss financially and transportation wise. I came to find out that this is a prevalent issue with Ford F-150 Triton engines and I ask that a formal investigation, recall and, if possible, compensation be awarded to me and others having suffered the same fate. The most recent case occurred on Saturday night April 1, 2006 when returning from a family wedding.
