I was driving on a highway at 55 mph in my 2004 ford 150 when i heard a loud noise from the engine. Found a spark plug had been completely blown out of the engine. I have done some reading and found this to be a common problem with ford's triton engines. Coil pack was sparking which could have led to a serious engine fire. Please have ford fix the problem. *tr

The #3 spark plug was ejected from the engine block. Upon inspection, the threads were stripped and damaged beyond belief. After tapping the whole, the plug was able to be replaced. A month later, the #7 plug did the same thing being ejected from the engine. Another round of fixing but this time the repair was not successful. The new plug did not stay in. Both of the old plugs are in pieces with most of the parts…

My gently used 2004 ford f-150 with approximately 63k miles is having motor problems. There is severe ticking/knocking of the motor for no apparent reason. There is also a gross loss of power and the gas mileage has immensely decreased. All the required maintenance and service has been consistently done on this vehicle and it is mainly driven on the weekends due to the fact that i am a nyc commuter. I have taken the…

Garage said this defect was common on triton engines. I called ford. Their reply was that they…

There is already a tsb for the problem but ford should really recall the cam phasers on the 2004 and newer f150's. Most people in this economy cannot afford to throw 2 grand into there car to have a factory defect fixed and ford won't step up to the plate. I have owned numerous ford's in the past and will never buy one again because of their lack of being a good company. I'm sure because the problem is on there…

On my 2004 ford f150 with a 5.4l 3 valve engine, the spark plugs all broke off when a tune-up was attempted. This is due to a know defect in the head design on the 04/05 models. The dealer charged me $904 dollars to change them. Ford is not reimbursing customers for this outrageous charge even though they know it is a design flaw, and are doing nothing to fix the problem. My understanding is that all of these…

Went to change the spark plugs. Ten days and $1000 later i have the truck back. If i had to do it all over again, i would sell the truck well before the 100,000 mile mark. Idiotic design leads to spark plugs breaking. Do not change plugs without discussing with dealer first. They have a special tool for extracting the broken part. It says a lot about the situation that ford had to come out with a tool to fix their…
