Trailblazer V6

Third compalint I've filed w/ the same car!!!! Seriously considering taking a loss just to get rid of it!!!!!! My service engine light has been on for months now. The code is P0440 ... I have seen alot of complaints w/ '03 models w/ this. Could be a number of things like the filler neck, a crack in a hose or gas cap. Mine IS NOT the gas cap. If so many people are having the same issue YOU should have to fix it. Your cars are defective and I'm losing money by owning one!!!! Never again!
