The car idles very low when stopped and sputters/putters like it's going to die. It has now actually died on me twice while driving, luckily when you put it in park and turn the car off and back on it starts right back up but you can see how this is a severe safety hazard. The first time it died I was stopped in the turning lane waiting on traffic to go by so I could turn left (this is the busiest street in town) I go to start turning left the car just shuts off mid turn crossing the other lane of the street, luckily I didn't get hit by oncoming traffic and was able to coast onto the side street that I was turning on and pull over and turn the car off and back on and drive it home. I took it to the mechanic and he can't figure out what's wrong with it so he gives it a tune up and now the check engine light won't turn off...fast forward to today it dies again at a stop sign with my [XXX] in the car. It is ESPECIALLY bad if you have the AC on it seems like it effects the electrical like the car is going to shut off when I am stopped and the ac is running, so I turned off the ac and it was still sputtering when I would stop but didn't die again. There is an entire thread of people with the same issue as me: [XXX] this car needs recalled it is a death trap.

My car turned off while I was driving and almost caused me to crash into an 18 wheeler. Thank God I turned on my emergency signal and the truck swerved!. I would of died. I was stuck in the middle of the road and luckily some passersby helped me push it into a commercial parking area. I tried to start it again and it wouldn't start. But, when I turn my key into the off position, my car tried starting by itself. It was scary. It was checked by a mechanic, prior to this happening, because the car was hard to start. The mechanic told me to find out if there is a recall. However, I did some research and there was a recall on the ignition switch and fuel pump. The ignition switch was faulty causing the car to turn off while moving and two people died as a result. I entered the VIN # and it didn't show any recalls.

NHTSA complaint #11522383 — an unverified report by a vehicle owner.
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.

Before I get into all of it there has never been an accident not yet at least. I do everything I can to try an stop that from happening, (but accidents do happen) only because I know my car could kill on me so I’m extra careful. 1) After I get gas I’m my car the car won’t start right away. I have to restart it a couple times an step in the gas an rev up wasting the gas I just put in to get it to start. 2) When I stop an start to pull out of somewhere on to a main road the car will just die on me so I’m stuck pulling out in traffic trying to get my car to start again. It’s when I come to a stop an pull out it just kills on me. So I have to make sure no one else is coming an I have enough time to be able to restart it otherwise I’m worried when I pull out of anywhere or stop an go that another car will smack into me because my car just died on me in the middle of the road/ pulling out an crossing lanes. SUPER SCARY! 3) Let get into the next issue so anytime I run my ac my car starts to do this jumping thing like it wants to kill on me not to mention it has killed on me with the ac on (I live in Louisiana an it’s too hot not to have ac plus I have 3 kids) what’s sad is the ac works fine but if you want the car to maybe not die then turn it off an you have a better chance of it not killing off on you but not always a guarantee. So ill run it for second to try an cool down so I’m not drenched in sweat but I have no other choice to turn it off so the car doesn’t just die on me. This refers back to the 2nd problem I make sure it’s off anytime I pull out of anywhere thinking that would help it from killing on me while trying to get out of anywhere but it doesn’t but I can tell you If the ac is on when I pull out when I start to go it dies right as I’m in the middle of the road every time never fails. Mechanics have replaced parts trying to fix the issue, but it still happens I can’t keep buying/fixing things for nada, ongoing problems since buying.

The problem that sent it to a different mechanic than the chevy dealer where it came from after a month and 900.00 bill for 550.00 ecm and diagnostic test they did without my permission, there labor for the test and ecm was a total of 900.00. Plus claimed it was throwing a code for a peddle that it needed. We just put a brand new peddle and brand new throttle body on it, it was idled to high, so reason for them getting it was to get the old ecm and new throttle sinked up to reduce the idle , at the time of it leaving me it started and ran just idle to high. Throwing no codes. They got it, claim it wouldn't start so did a diagnostic claimed it needed a new peddle. I said I'm coming to get it, they didn't tell me at any time I couldn't drive it home. I left there lot and pulled about 150 feet off the side of road because it wouldn't shift. Called them , botched did no good. Called same tow truck to tow it home. Got here it was idled normal but was throwing a different codes, I turned the car off it wouldn't stop running for about 3 to 4 minutes, then it died. I had it towed to different mechanic for the ignition to be replaced. He said it was throwing a couple codes still ignition not fixed yet, and it ran for about 15 minutes after shutting off the key. At no time here or at the new place did it throw a code for a defective peddle. So now it's be gone for 2 months , new ecm , new throttle body ,new peddle, idle is fixed and car runs but won't shift. Codes its throwing is now are just needing coil on #4 checked and throttle position sensor adjusted. So far that's it. 2 months later. Still not ready for pick up.
