2010 Chevrolet Cobalt: fuel pump failure

Filed May 16, 2023 · Engine, Fuel system · NJ

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 covered, fixed, or made right by GM is something that doesn't make sense. I have also seen, that in 2021 an investigation was launched specifically into this exact issue with the 2010, as well. I'm carless right now, with no answers from Chevy other than that it's not part of the recall, yet it's part of the problem. Something is VERY wrong here. It's shocking they wouldn't recall a vehicle knowing it's dripping gas, pooling gas, it's such a hazard for not only anyone driving them, but anyone driving near us or even PARKED near us. Please help do something! Also I have videos of my car dripping, 2 days prior to it not starting, if there is somewhere I could send those as well.

Fuel puddle under car- shop had to replace fuel pump as it was leaking on top of the tank. Gm refuses to pay for the repair as they say only 2006 thru 2009 chevy cobalt's have this problem. This is a 2010 (last year made) this is very dangerous senario - does someone have to die before a recall is mandated.

Fuel line rusted above the driver side wheel and burst while driving down the road. Fuel pump shorted out and died while driving a few months later.

There is a severe fuel leak on the fuel line near the back of the car on the driver side. It appears to be a heavily corroded area. While the vehicle is running it is a steady leak as the fuel pump is running. When the engine is off the leak eventually stops once all of the fuel in the line has drained out.

Fuel starting leaking by the left rear wheel. The fuel is dripping from the fuel and vapor recovery lines around the area where there is a holding clip. Looks like it could be spraying out above that area possibly where the fuel pump is located. I noticed the smell of fuel first while driving. Once the vehicle stopped I found gas leaking as described above.

I noticed a gas leak under my rear passenger seat and can smell gas outside of the car. Took it to a garage and they said the fuel lines are leaking where they connect to the fuel pump, but they have seen many cobalts come in with this issue and it's covered under recall. I checked with gm, my VIN has no recall for that issue. There is no rust under the car so this is definitely a manufacturing issue.

While driving in a suburban area , smelled strong gasoline odor coming from under the car. At destination, others noticed as well. Immediately parked car, looked up the issue and realized the fuel line/fuel pump/gas leak is a cobalt problem, yet not a recall. We got it serviced, but out of our pocket expense.

After smelling a strong smell of gasoline while driving on the interstate, I pulled my car over and noticed a huge puddle of gasoline on the ground and still steadily pouring out. I immediately drove it home and parked it and took photos and a video of the defect. I had lost over half a tank of gasoline in just 30 minutes. With this fuel pump leak being near the exhaust, a high probability of explosion can happen and has happened to other models of this vehicle, different model year. I have seen that the chevrolet cobalt 2007-2009 have been recalled due to fuel pump leaks, but the 2010 has suspiciously been left off of the recall.
