The manufacturer was contacted and offered help with a new vehicle. The contract stated that the failure was related to NHTSA Action Number PE20011 (Fuel System, Other, Fuel/Propulsion System, Fuel System, Gasoline). The failure mileage was approximately 107,000.”

“My car had a fuel pump go, then within MONTHS, another. We then dealt with the SAME problem symptomatically, and was told it was the fuel pump sensor. Within the last few weeks, I am having all the same issues-including the car intermittently not starting, gasoline leaking from the vehicle, both noticably missing from the gauge (i.e 1/8 tank less than night prior), odor of gas in the car, stalling out while driving and trying to start it, but also now dripping gas from the car. A new issue popped up, which is the dash light coming up saying "check gas cap". This past Thursday, my car wouldn't start again, and has not started since. It's concerning that the Chevy Cobalt has had recalls for the same exact problems, literally thousands of complaints that mirror mine- for every model year EXCEPT the 2010. It's also interesting that they also stopped producing the Cobalt entirely in 2010 too, but considering the amount of faults and issues I've seen documented in every year model it's not a shock. I'm concerned that despite the amount of complaints that include 2010 models, they were excluded from the recall and seeing that my situation is another one that won't be…”

“Fuel lines are both leaking on the driver-side of the car, about halfway back along the length of the vehicle. I've sent it in for repairs, but I know I'm not the only one with this issue. The car has been driven gently and only has 52,000 miles on it.”

“The fuel line was leaking gasoline. It put the safety of the driver and other cars on the road as the car was leaking gasoline as it drove on the highway and city streets. The problem was confirmed by a service center and the fuel lines were replaced. No inspection by manufacturer, police etc. No warnings at all, car was starting rough and/or not starting at all.”
