Fuel lines are both leaking on the driver-side of the car, about halfway back along the length of the vehicle. I've sent it in for repairs, but I know I'm not the only one with this issue. The car has been driven gently and only has 52,000 miles on it.

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.
Fuel line was leaking on driver's side rear wheel close to heat shield and muffler. Cost me 1,000 to have lines replaced.

Fuel line leaking. Driver side rear of car just behind passenger door where there is a heat shield around it
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.

Fuel line leak under rear door on drivers side, not far from the tank
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.
My car was smelling like gas, and I noticed a significant drip under my car. After investigating, it looks like its my fuel line that is corroded and leaking, in the back left of the car.
The undercarriage of my car is rust free. However, in front of the driver's side rear wheel there's a fuel leak. And only leaks while running.
