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.

Incident

Nov 30, 2021

My 2010 Cobalt has been leaking fuel from the suspected fuel/vent lines at or near the rear driver's side wheel well. There remains a constant puddle of fuel noticed every time after car has been parked. The issue was first observed by a strong odor inside the cabin of the car. The amount of fuel leaking is severe enough to significantly effect my mpg and fuel pressure. The lack of fuel pressure results in delayed starting or extended cranking of engine until enough pressure is built to start the engine. The leaking fuel is a significant fire Hazzard.
