   The fuel tank has an evap leak that somehow breaks on top the tank so it leaks the gas vapors and could potentially start a fire but the part that breaks is a non serviceable part so it can’t be fixed without purchasing a whole new gas tank that isn’t cheap. My other concern is the infamous grounding issue with the wires on the ground g105 I believe right next to oil filter that grounds the transmission and engine control modules well it shorts at times when driving and…

   My 2006 Chevy Cobalt has a fuel leak which was recently a recall. I have been told by several dealerships that it will not be repaired for free. How can this be? I didn't know recalls expired. It's a safety issue and the manufacturer's responsibility. Please advise me on next steps.

    I began noticing a slight drop in fuel mileage at first. Started smelling fuel while parked and only getting 200 miles to a tank. Noticed the supply and return fuel lines where damp. Dropped the tank and the fuel lines at the pump were cracked a little. I temporarily fixed thos with jb weld but dont expect it to last.

    Fuel lines are rusted where the heat tape is around them by the exhaust. This has caused them to rust and no is leaking fuel. I am worried that it's going to catch fire. This is my daughter's car and is a very poor design.
