Engine Exhaust System problems of the 2003 Ford F-150

As we started the truck, we heard a loud pop and then the engine was running rough. I could smell gas burning not in a good way, so we turned off the engine and popped the hood. There was gasoline running under the truck, and gasoline coming from the exhaust. A passerby informed us that the F-150 with triton engine is notorious for blowing spark plugs and proceeded to point out which spark plug had blown. I researched this issue when I arrived home after our truck was towed to a mechanic, and discovered that just about every F-150 owner goes through this. Why is this not a defect that Ford is being required to fix? do people have to die before a defective part is taken care of?.

While driving home from work my wife had a spark plug blow out of the engine, fortunately the 2003 Ford f150 supercrew pickup truck didn't catch on fire, I drove the vehicle another 15 miles to the mechanic not knowing what is wrong , I thought the it was just a bad exhaust leak but I found out the next morning the grim news that in fact the spark plug was the problem, I was told the repair would run between 700. 00 to 2,000. 00, shocked by the cost of repair and the problem of which I have never heard of I went online to check it out. To my surprise I found this is a major problem with the Ford triton engines, so I thought Ford would do the right thing I called Ford and explained my problem, only to be told that it was my problem and Ford wouldn't do anything for me. I know I'm not the only person that has had this problem, in fact if you do any research online you will see that hundreds and perhaps thousands of people have had this problem, I would hope that maybe you can help me and the other people that have had this problem, thanks in advance tim walsh.

Excessive exhaust noise when warming up and cooling down such as loud popping noise.
