Tank Assembly problems of the 2005 Kia Motor Optima

The gas tank on this 05 kia was leaking at 78,000 miles, took it to dealer, I had to pay for labor, they furnished the new gas tank cost me $330, now at 98,000 miles it is leaking again and kia is refusing to fix it, I feel this is a safety issue, going on 3 gas tanks less than 100,000 miles. Paid dealer $95 to inspect the tank as told by kia consumer dept, dealer didnt look at the tank instead said it needed a gas valve first $400, before they would look at the tank. The dealer is lee kia, in ft walton beach FL. So I guess I just continue driving car till something real serious happens? need some help here please thank you chalmer & kasey berry.

My car began to leak fuel. I sent it into the dealer who found that the gas tank was cracked on the top side of the tank. I was further advised that the leak was not caused by any normal wear and tear or any damage. The car is still under warranty, and I replaced the fuel tank.

I am about to replace my gas tank for the 2nd time in less than a year. I am told by the dealer that the composite tanks are prone to puncture or splitting on the seams.
