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.

I purchased a 2010 Chevrolet Cobalt from a used car dealership in July of 2019. 3 months into having the car, as I, my mother and 6yo daughter were driving on the highway at approximately 60mph, the car started to jerk and slow down. The 'engine reduced power ' message came across my dash. We we're almost side swiped and rear ended. Only for the fact that a fellow motorist stopped behind me to help merge traffic to keep us from getting hit, is what kept us from being in an accident and pulling over to the shoulder. This is so dangerous and I can't imagine as a mother how losing her life, or the life of her child would have been devistating because of a manufacturer's error!

I just bought this car..2010 Chevy Cobalt with 176,000 miles two weeks ago with all of the money that I had. I noticed that it had a dealers tag, but he wanted to meet me at a store and claimed that the car was perfect.day two it stalled & has continued to randomly stall & wouldn't start til the 3rd try. I tried, but it's impossible to contact the seller. Autozone said it had 17 codes, but could just be the C20? sensor. Then last night it would start, accelerating to about 5 mph, then stall & I had to have it towed home from a busy area, and now it won't turn over or start at all. Im a grandmother on my own with a part time job and have no money left for repairs or to start all over. I'm hoping there's a recall that could help.I don't know how to find this man as the title had another persons name on it, not that it would do any good.

I was driving home this morning and a deer jumped out in front of me. I slammed on the brakes and the engine shutoff. Making the power brakes and steering shutoff. Extremely dangerous not to mention if there is no power most likely the airbags will not deploy. A serious issue for a car that is less than 6 years old with around 80,000 miles on it. Just a disclaimer it is an automatic so there is no clutch.

After starting the car the transmission bucks rough causing the front wheels to slip and causing the stability light to come on. Sometimes the vehicle bucks so hard and so many times it will stall out creating a very dangerous situation... my son's co-worker and friend has the same car and the same exact problem... I feel it is an issue with the transmissinon
