I started smelling gas and that went on for 2 months now at a idle you can see fuel dripping off the fuel tank coming from the top of the fuel tank. I believe the metal liine have rusted.

The contact owns a 2007 Chevrolet Avalanche 1500. The contact stated that while parked, the vehicle would not start and the engine warning light continued to illuminate in the process. The vehicle was towed to a dealer, where it was diagnosed that an unknown part related to the fuel system needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was not notified of the failure. The failure mileage was unknown.

The vehicle is equipped with the ability to handle flex fuel after you run the flex fuel then switch back to unleaded the fuel pump is damaged, I've spoken to other owners that own an Avalanche same model year and they are experiencing the same issue but GM ignores this. Can you offer any feed back for this ? if so thanks.

This vehicle has had oil consumption problems since purchased. It runs out of oil 1500 miles after an oil change. Several consumer complaints have proved this is a very common problem and suggested reporting it to the epa. My truck now needs a new engine because of this common defect with the afm and bad lifters in the 2007 Chevrolet Avalanche. It is completely abnormal for an engine to burn this much oil into the environment. Not to mention the consumers who are now being forced to replace engines due to this problem. It needs to be fixed.

Cracked dashboard on passenger side where airbag is fitted. Upper lefthand side of airbag. Traction control/stabilitrac system: Service indicator warnings activate, switches from 2 wheel drive to 4 wheel drive high even though selector is in 2wd mode. The first occurrence of this was at 70K miles, then again at 90K. Then again at 97K the transmission was damaged and needed to be replaced. Again at 101K miles the ringgear in the rear axel was destroyed. Rear axel was replaced. Fifth time for those counting, 116K miles service stabilitrac and service traction control warnings, switching from 2wd to 4WD high while moving, while parked, selector in 2wd position with someone at the wheel or cab empty. Evaporative emission control warning. Check engine light on, code comes back to eec. Indicating a leak in the return line. The first time this was replaced at 70K miles, this is the second time. And no it is not the gas cap being loose or needing replaced. The first time there was "water in the connector" (yeah sure).
