I have noticed a strong gas smell coming from the car right after I parked my car. And discovered gas leaking through the gas lines very fast. I've noticed that many Chevy Cobalt cars encounter this issue when I researched this problem I have. I am surprised it has not been called for recall

While the car is running or while the fuel system is still under pressure, for example after having been driven there is a steady fuel leak in front of the drivers side rear tire. I have parked the car only to have lost 1/4 of a tank of gasoline to the leak. There is a very very strong odor of gasoline that permeates the car. Sometimes the car will hesitate to start, the engine continues to crank after I release the key and then it finally catches and starts.I understand this has been recalled in only certain states.

Fuel leaking underneath car. I filled the tank fully and drove to work 5 miles. Afterwork I get in car and as I got closer the odor of raw gasoline fumes were noticed. I drove home parking on dirt no leaks seen next day as I'm going to work, I look at the gas gauge to see nearly a 1/4 of tank is gone. I get to work, let the car sit for 2 hours. When looking underneath the car, I had noticed a puddle of gasoline under the car with again a strong odor of gasoline. Car is not driven in the winter and is kept in garage during winter seasons

Fuel line near driver rear tire leaks. I saw an article online about this issue beginning to pop up. Mine started leaking enough to cause driving issues. Temp fix, just put a rubber fuel hose on with clamps. To poor to fix an issue like this, it's not cheap.

Increasingly the vehicle is not operating properly. The lighting is not consistent and the smallest addition of extra features requiring power (ex: Using one or more window controls, heater and or defogger, lighting in dash at full capacity, musical performance, radio and bass, etc) will cause the power of existing devices to flutter or surge for example the headlights will dim out when turning the windows down or the vehicle will begin to vibrate and shake even more almost as though it is overpowering and wanting to shut down or quit. Also the rpms will feel like they are hiccuping or bouncing down and up more than usual and at random times and speeds at times seems like its going to red line even if you take your foot off the gas. This is also a bit of the same type of issue but it is the opposite when you push the gas it hesitates or something like that glitches or jolts and gains power very slowly and has a hard time accelerating and gaining speed (seems gutless?). and at stop lights and whenever parked its rumbles and shakes all together let alone if you are using the radio or heat etc it's loud enough to have to get the people in vehicle to almost yell when talking over it or if you are in a drive through the person can't hear you and either have to stut off the engine or speak to them in person at the next window. Also when you are slowing down to stop it almost seems the engine will be faster than the body or something like that (I know sounds crazy but I don't know how to explain it any other way). I've come to the conclusion that it will be fuel and or electricity related or both. Its also randomly showing a few different codes and then suddenly they go away all to do with fuel pressure or syster or evap type thing. Without clearing them they resolve themselves without any work or anything witch also seems very oddto me. Thankyou in advance for reading.

There is a very strong odor of gasoline coming from inside and out of my vehicle when parked and engine is off/on and when the vehicle is in motion. The smell has made my children nautious and given us headaches. And after doing some research I'm seeing very similar cases with the Cobalts of other years that are being recalled but mine is not. I beleive it is the same issue as the 2009 Cobalts aswell as the Saturn ions.

The car is leaking fuel, it first came to notice when parked in my garage, the odor of fuel was so strong I was afraid to open the garage door or start the car for fear of a spark starting a fire and burning my house down! the dealership told me the fuel lines are corroded and leaking. I am shocked that such a critical component is made of materials that could ever be compromised during ordinary use, especially when leaking gasoline is such an obvious safety hazard. I opened a case with Chevrolet, #[xxx], but was told fuel lines are considered a maintenance issue. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
