Consumer was told that the 2003 Avalanche was not a standard tank and that the fuel leakage issues were not their responsibility. The consumer was told the gas tank had a manufacturers defect that caused it to be too thin around one of the seals. The tank was so thin, that it could be pressed as if it was soft rubber. The soft area had become so weak, that gas was leaking from the vehicle.

2003 Chevy Avalanche fuel tank began emitting a gas smell when the vehicle was more than half full. Over time small puddles of gas could be seen under the vehicle when it was stopped. The mechanic found that the tank had a manufacturer's defect, which caused it to be too thin around one of the seals. The tank was so thin in that area, that one could physically press it down like soft rubber. The soft area had been steadily weakening the seal until it finally failed causing gas to leak out of it.
