I notice that the tank has been leaking fuel. This occurs when I fill up the tank and/or the fuel swishes or moves around. This happens on the rear left tire. It seems to get on the exhaust or heat up and smell excessive fuel. I noticed this when I would park for at least 20 mins on a full tank. I am a fuel tank engineer and see this as a poor design possibly.
Smelled fuel and found fuel leaking on drivers side rear. Took to mechanic and was shown that all fuel lines were rusted from the gas tank to the engine. Called Chevrolet and there are no recalls on this vehicle and made complaint that this is a dangeruos problem for not only fire but explosion. Found other complaints for this on carcomplaints. Com.
