The fuel pump failed and had began leaking profusely. The car was brought to the Chevy dealership where I was told it would be fixed under special coverage 12191. Chevy had tried an aftermarket part to fix but it would not seal properly and continued to leak. I got in contact with General Motors who said a new part had been ordered, a week later they told me there was no new part as they discontinued it. They are now saying that it isn't their responsibility to fix the car due to its mileage even though special coverage 12191 specifically states no expiration due to mileage. They are offering me a credit towards a down payment which I do not want as I am not interested in having a new car payment, i want my car repaired or to be compensated once they total it out. …

Around Dec. 22, 2021, I started smelling gas outside and inside of my car (particularly the right back seat near the gas tank). I took it to a local mechanic and he urged me to take it to the dealership for service and to not drive the car a lot because it could be dangerous. He said it was the gas tank pump and that there was a recall that I should look into. I took my car to a local dealership for service and upon inspection, they removed and replaced the fuel pump and plastic lines - they confirmed there was an issue with the gas pumps.

Started smelling gas when driving vehicle. Found fuel leak on top of fuel tank. Took vehicle to Mesa Auto Works [phone]) on [redacted] and they diagnosed a Fuel Pump Module broken and leaking fuel. Replaced unit at a cost of $730.22 with the fuel pump module costing $382.80. This defect could have resulted in a car fire and or worse. Definitely a safety issue. I have searched online and found many other complaints about this same defect. [redacted]

I observed my mother's 2007 Chevy Cobalt was leaking fuel near the rear tire by the fuel tank. I inspected the tank with engine off and it does not leak. Only with engine running. I lowered the tank and observed a small crack on the plastic return line on the fuel pump module. I started looking online and could not find a replacement part that was plastic. I then conducted more research and found the recall. I asked my mother and she stated she never received a recall. The recall was issued on 09-19-12. NHSTA ID#12v459000

Back near the rear wheel the gas's lines are so rusted out it's because of the manufacturer put a heat shield on it and it trapped morsure and water in it and rusted the lines so bad there's barley anything left this is a known issue in Chevy Cobalt ls coupes I own a 2007 Chevy cobalt LS coupe I don't understand why there isn't a recall on all 2000-2012 Chevy cobalt models or a reimbursement for the people who bought that had to replace the gas lines because of that

Strong smell of gas when driving, also strong smell of gas around car in general. Underneath the car you can see gas pouring from fuel tank, looks like it's coming from top of gas tank. Whenever I park in a parking space, in my driveway or park for any period of time I always leave a puddle of gas. I just started my car and looked underneath at gas tank, there is a steady stream of fuel coming from somewhere on gas tank.
