In past two months, I smelled some gasoline fumes inside the car when starting or/and shutting the engine and the odor became stronger over time. I have looked around and under the car but I couldn't find any evidence of gasoline leak. Then on few days before September 27, 2021, I had a bit of trouble starting the engine as I had to try twice before I got the engine running. On September 27, 2021, I then found the leaking of gasoline from a fuel line under the car next to left rear wheel well. It was dripping and left puddles of gasoline on the street. I decided not to drive it now because of potential fire from drippings. Now my car is now parked on the driveway with a piece of cardboard catching the drippings.

Corrosion was found in the fuel line near the left rear wheel causing a fuel leak. I am currently having the fuel lines replaced as the leak was near the exhaust and the car was deemed unsafe to drive for fear of catching fire.

After taking my car to a mechanic for an oil change, I was informed my car had a steady gas leak near the left rear side of the car. The mechanic informed me the fuel had corroded near the plastic clip holding it onto the body. After just 15 minutes, a fairly large gas puddle had formed on the ground. I was advised not to drive without getting it fixed, as this would be a fire hazard.

On 6/28/2021, my wife & I took our 2010 Chevy Cobalt Sedan 4 door into down to get some dinner. When we went out to the garage we smelled strong gas fumes which we thought was odd as our garage never smelled of strong gas fumes in the past. We got in the Cobalt & turned the key & it didn't start right away, it took a little bit for it to turn over which I thought was odd as we haven't experienced that before. We put the windows down as the inside of the car had a strong gas smell. There was no warning lights on the dashboard & no prior warning before this issue. Returned home parked car in garage, went back into garage & noticed even stronger smell of gas, looked under the car & noticed liquid under back driver side door which was gas dripping down onto the garage floor, I was nervous of the fumes collecting in the garage & potential fire hazard I put the car outside & placed a bucket under the car to catch the gas to stop it from dripping on the driveway. Also noticed the silver heat shield material was spongy feeling had liquid feel to it which I assume is gas as it was dripping right next to it? Looked on Google noticed other consumers having the same issue of gas dripping from the fuel line. Going to call a Chevy dealer to see what options are as I don't feel safe driving the car knowing its dripping gas & potentially collecting in the silver heat shield material. Chevy should issue a recall to repair the issue & prevent future safety hazard waiting to happen.

A strong gasoline smell was noticed after parking the car in the garage and stepping out of the car on the driver side. The drive before the gasoline smell was noticed consisted of around 5 minutes of city driving, 10 minutes of highway, followed by another 5 minutes of city. The smell does not seem to be coming from under the hood and snow melt made checking for drips under the car difficult. The cause of the gasoline smell is unknown.

I entered the garage and smelled the strong odor of gas. The car had recently been parked in the garage after returning from a 115 mile interstate trip. After investigating I found a puddle of gas on the cement floor under the car in front the the rear driver's side tire. I started the car and backed it out to the driveway during which the gas leak was much more substantial. The gas line is very corroded where it meets the insulation wrapping near the car's exhaust pipe. It appears the gas line failed at that spot and will need to be removed and replaced.

Fuel is dripping from under vehicle, ahead for rear left wheel, forming a puddle when parked. Fuel stops dripping at some point after engine is shut off presumably when fuel line is drained. Engine is difficult to restart, requiring about 10 seconds of cranking before starting, probably due to fuel line having to be refilled. Have an appointment with dealer to check and repair the fuel leak.

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.

Started smelling gas while driving the car. After I parked the car, I noticed something dripping from right behind the drivers door under the car. I had someone look it and they said that it was definitely a gas leak. Once we looked under the car, we noticed that the gas lines were rusted and that is where the gas was leaking out from.
