The spark plug in me Ford F-150 5. 4ltr engine blew out of the #2 cylinder. All engine rebuilding shops and repair centers say this is common in Fords. They finished my sentence when describing the problem. Please enact a recall on this problem. As I read this is an issue. Cost me 500. 00 dollars to fix and I worry about the other 7 plugs. . . $3,500 to repair.
While traveling @ 65 miles per hour down a highway, the number 3 spark plug & coil blew out from the head causing damage to the coil & spark plug itself. Our 2003 Ford f150 supercrew lariot pick-up truck, which is in excellent condition, had to be towed. This is the first time this has happened to our vehicle. The local Ford dealership recommended a quick fix of a spark plug insert after the plug hole was retapped while stating several times that there was no guarantee that this would work. Another option was to replace the heads costing approximately $2500. The dealership also advised us that they were aware of this problem & has seen it happen on a variety of Ford vehicles. We're extremely lucky that our vehicle didn't catch fire, as the coil that blew hit the fuel rail, which is held in place by two 8mm bolts. This experience is extremely frustrating & concerning to us as if we spend money going the route of the insert, it may last for one trip down the road & give out. It's disappointing that Ford isn't standing by their product & fixing it appropriately. This is a well known problem that brings with it severe safety issues. We will not be purchasing a Ford vehicle in the future.
This is the second occurance that I have had a oil seal or gasket on the engine after driving 80 +mile per hour. I had my truck less than three years. I have also noticed it vibrate when reaching the speed mentioned.
I purchased an 2003 F-150 stx 4x4 in July of 2003. Less than 1 year later the air conditioner had to be replaced. Stopped working with no noticable problems. In the next 12 months the gear box has been replaced twice, I called our local dealer and told them the transmission was shifting harder than usual. Took it in and they couldn't duplicate or correct the problem. It continued, and less than 6 months goes by and I am sitting at a red light downtown louisville ky and the light turns green I pushed the accelerator and the truck goes backwards! thank god no one was behind me! after 15 minutes I finally get the truck to the side of the street and call Ford roadside asstistance. That was a joke in itself. Finally 4 hours later the truck is towed to our local dealer and they call the next day and say it is the transmission. Duh! I told them that months ago. They "fix" it and it still is not right. I have even taken it to another dealer and I have contacted Ford. The second dealer could not find a problem, so far all I get is, yes, it does shift really hard but we can't get a code to see what is wrong with it! I am still paying for the truck and it is now under the "extended warranty" this is completely wrong! no one should pay $36000 for a truck and have this much go wrong with it! any help would be appreciated.
