2004 Chevrolet Trailblazer fuel system problems

I bought a chevy trailblazer in march of 2004, brand new. In november 2004 I smelled a strong odor of gas fumes and took it to the dealership for repairs, they fixed the gas odor, but it did occur to me that my trailblazer may have been causing the severe headaches I had been having since march of 2004. My headaches did decrease in frequency then cease after I quit driving the trailblazer. My husband then started driving the trailblazer.

Tl*the contact owns a 2004 chevrolet trailblazer. The contact stated that his gas tank filler neck failed and was loose. As a result, fuel leaks out. The manufacturer and dealer stated that the VIN was not covered under the recall and they only offered to pay 50% of the repair cost. The failure mileage was 55,000.
