Cobalt 4-cyl

  • 46,134 miles
This vehicle has only 46,134 actual miles. I am the 2nd owner and purchased this vehicle from a Chevrolet dealer as a certified pre-owned vehicle. The vehicle was being parked in my driveway and after I stopped the car, I smelled gasoline and about a pint of gas leaked out of the ground just in front of the drivers side rear wheels. Fortunately, I was parking in the open driveway and not in my garage. I immediately took the vehicle to a licensed mechanic and he was able to repair the vehicle. It is back on the road. I read in the newspaper that other Cobalt owners have been having the same problem. I encourage your department to look into this as a more serious problem than just routine maintenance. I have uploaded the bill for repairs. $952.09. Thank you, [xxx] redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Keep smelling fuel vapors on the rear left side of the vehicle. Checked the fuel filter and it seems to be working despite my gas mileage getting worse and worse. I've been burning a full tank of gas going less than 250 miles when I should get near 400 miles a tank.

An unknown dealer was contacted and notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

Fuel leaking from driver's side in front of rear tire. This is a fire hazard and GM refuses to recall the issue and cover it, even though this same issue has impacted numerous individuals. We are coming out of our own pockets for almost a thousand dollars for each instance at certified Chevrolet dealerships. This is unacceptable. Https://www.cargurus.com/cars/discussion-T33495_ds573685 if all these people are reporting the same issue, imagine how many aren't on online forums with the problem. When you see things like this, it needs to be covered. Again, completely unacceptable.

09 Cobalt has fuel leak with puddle of gas in front of driver rear tire. This is a problem noted by many owners of this car. 09 Cobalts purchased in about 6 states have been recalled for this problem. It seems that for safety reasons this recall problem would apply to all models no matter where purchased. I'm assuming the car purchased in AZ was made the same way as one purchased in pa. I noticed the leak when car was sitting in my driveway.

Car has terrible start first thing in the morning. It went from Washington to gulfport Mississippi. Started about a week ago smelled gas. Looked under fuel tank and found a sizeable puddle or fuel which I assume is pressurizing as it sits and then has to pressurize the fuel system again when it starts. It's practically a bomb with wheels and my daughter sits in it. It will be fine starting for about 10 minutes if you shut it off and crank it after it will do that all over again
