Q&A

 Master

Is your car still under Chevy warentee, its too new for this type of problem? The tank will have to be removed and the seal or gasket causing the gas smell replaced. Has you car got a Check Engine/Service Engine Soon light on, (even if its not if you smell gas it will store a pending code and will likely turn on the light soon indicating an evaporative emission leak) this is covered under Chevy emission warentee.

If there is indeed a gas leak from the fuel tank of your 2007 Chevrolet Cobalt the fuel tanl will most likely need be removed to pinpoint the cause of the leak. Has your check engine light been on possibly with a code for an evap system leak? (Code P0442 or P0445.) If so that would also indicate a fuel or evap system leak. I would expect it would take 2.5 - 3 hours to remove your fuel tank, confirm and repair the cause of the leak, and reinstall the tank. That would put the labor cost in the $175 - $280 range plus the cost of any parts need to make the necessary repairs. With your Cobalt being a 2007 model I would strongly suspect that this repair would be covered by the factory warranty. It may be worth a trip to the dealer to find out.

i have a 07 cobalt ss and have been having a little trouble with mine to. but i would think your warranty would cover that. it should if you have a bumper to bumper i have 86000 miles on mine and my warranty is still going to cover me until 120,000 i would go talk to your dealer before you do anything hope it does good luck

I had the same problem, fuel pump had to be replaced. There is a recall, but only for certain western states, which my car was purchased in but not residing there now, so after cussing and discussing with chevy customer service they fixed it free of charge. But I got considerable flax from customer service first, They kept telling me no recall, but i gave them the bulletin number and they changed tunes in a hurry.
