Fuel starting leaking by the left rear wheel. The fuel is dripping from the fuel and vapor recovery lines around the area where there is a holding clip. Looks like it could be spraying out above that area possibly where the fuel pump is located. I noticed the smell of fuel first while driving. Once the vehicle stopped I found gas leaking as described above.

There is a severe fuel leak on the fuel line near the back of the car on the driver side. It appears to be a heavily corroded area. While the vehicle is running it is a steady leak as the fuel pump is running. When the engine is off the leak eventually stops once all of the fuel in the line has drained out.

In July / August of 2019 I was smelling gasoline while my vehicle was parked. I eventually noticed a large puddle of gasoline under the parked vehicle. After calling my stepfather who is a mechanic I took the car to a local shop who confirmed I had a corroded fuel feed line that needed to be replaced and completed the repair for me.

Parked in driveway, started vehicle and the fuel lines started pouring gasoline out. My wife and I noticed the smell of gasoline and inspected around the vehicle. It was coming from just in front of driver side rear wheel where the fuel lines and exhaust system both go up and around the rear axle. Looked up online to find that the reason is poor design because of a heat shield that wraps the fuel line to protect from the heat of the exhaust pipes also acts as a sponge as it stores moisture against the fuel lines creating a point of failure.

The fuel line has rusted and gas is coming out just in front of the driver side rear tire. It's a 3-4 inch section that is completely rusted away and is common problem with this vehicle. It's a significant amount of gas that comes out when you start the car which is a real fire hazard.

I pulled into jiffy lube and they said they smelled gas. I took it to a mechanic and they said gas was leaking from fuel lines. They installed new fuel lines. I paid $744.15 on June 6th 2019 and still have receipt. I don't know when or where it started leaking. I heard there may be a recall and would like to know how to get reimbursed. Thanks.

Fuel smell by driver side passenger door. Hard to start, due to loss of fuel pressure. Fuel puddle on the ground. Not safe to drive, fuel line leak next to exhaust, fire hazard. With all the fuel leak reports same area, surprise there is no recall associated with this issue. This is a huge safety/fire hazard, come on GM figure it out.

After parking I noticed a fuel smell and found a small puddle under the back driver side door. Two drives later the leak was a pool and the car started having difficulty starting (due to an empty fuel line). I limped it down the road to my.mechanc who identified it as a leaking fuel line. We replaced both lines. Normally I wouldn't file a report, but I just saw an article about an investigation into Cobalt fuel lines. I figured I would create a report in case it helps.
