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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Spark plug blew out from engine. Normal driving conditions, failure caused lack of driving power. If incident had occurred during rush hour, accidents would have occurred. The engine block had to be re-tapped, plug and coil replaced.

1998 Ford Expedition after reviewing all the complaints listed I realized I had experience similar ones for instance spark plug blew out in Dec/02. In Aug./03 the tie rod broke. We have had trouble with 4X4 working or in this case not. When switched in while lifted on a hoist it registers, but when on the ground it doesn't work. Something to do with the weight. Also the door locks no longer work, something to do with a sensor. Interior light stays on in hot weather. And the list goes on.

Spark plug was 'blown' out of cylinder head on 1998 Ford Expedition. Ford enthusiast website showed this occurring to several people. The expense is $4100 and it seems to me that this is a defect in manufacturer. There was no warning, nor any recent service performed other than oil change.

Repeated problem that has escalated to a suggested engine replacement. The #4 coil has been repaired 10 times. The vehicle warranty and extended warranty have been exhausted. Ford has repeatly failed to find the real problem. The customer service department representatives and supervisor have said that there's nothing Ford can do about my problem. "it's the Ford policy."

One of the spark plugs blew out completely as engine was running, repair shop said it was very unusual and could be some type of defect because they have never seen this type of failure before with so few miles. The threads were completely stripped out where spark plug screws into head.

While at idle the #3 sparkplug blew out of the cylinder stripping the threads. The repair facility estimates $2000 to repair. This is exactly like ODI #743868. There is a defect in the heads. This engine was replaced twice at about 30,000 miles because of leaks in the headgasket. The current engine only has 34000 miles. When the spakplug blew out it spewed gas over the engine creating a potential fire hazard.

I called Ford consumer relations and they played dumb like they have never heard of this problem. I was steamed. At least admit you have a problem I told them. After first talking to some lackie, I got a "supervisor" who was very arrogant. He tried to blame it on a lack of "Ford certified" maintenance. If they would have just admitted the problem and charged me cost for the replacement instead of making even more money on their own design flaw, I would have been happy. They even charged me $30 to diagnose the problem! I mentioned the tsb, but again, he played dumb and said he would have to look into it.

I uderstand this faliure is quite common but at only 19000 miles if this were to happen on the highway, and it is likely to it would result in loss of steering and brakes.

While traveling at high speed the #3 spark plug on the left hand side of vehicle detonated, stripping the spark plug threads and incapacitating the vehicle. The Ford dealer wants to charge us $2000 to fix what is essentially a known defect. Ford redesigned the spark plug housing with a reduced number of threads resulting in this catastrophic failure. This defect has been documentented on a number of message boards.
