My check engine light came on. After linking to the computer I had a code # P0442. After I, and my mechanic inspected the vehicle, we found that the gas tank was cracked and leaking. I had to replace the faulty gas tank, for an expensive fee. I called Chevy, and to sum it up, I was left to work this problem out on my own, with no financial help from GM.

Strong gasoline smell in passenger compartment. Smell is strongest underneath vehicle fuel tank. Have not yet had vehicle serviced to determine root cause.

Service engine light came on. My private mechanic found it to be code P0440 indicating the fuel evaporation system had a problem. Initial inspection found nothing but upon performing a smoke test of the fuel system, the fuel inlet nozzle on the fuel tank was found leaking. Only fix was to replace the tank. Total cost was $2200. I notified GM and was told they cannot do anything since the vehicle is out of warranty. Fuel tanks should not be leaking, especially when they are only 4 years of age. Many other similar complaints on this website show this to be a common problem with this vehicle. A recall to check all fuel tanks should be done before someone is killed over this poor design/quality issue.

2003 Chevrolet Trailblazers 3-4 weeks ago my service engine soon light came on and I took it to the dealership who showed me a leak at the junction of the gas tank and the hose from where you fill up the tank. The service man tightened the clamp. The light came on again and I took the TB back and was told the connection was cracked and that the tank had to be replaced. I haven't been in an accident, haven't run over anything etc to cause this. I am having the tank replaced--
