Failure Date: 09/04/2020

Have been smelling gas for 6 months now. . . Right after shutoff in driveway. . . . . Driving to a park today about 6 pm. . . Another driver pulled up to my side, and said I was leaking gas or something. . . Was behind me at stop light . . . Got to the park and stopped car. . Autistic child in back seat with little dog very scared. . . . . . . Sent her across the park to a bench to sit. . . . . Looked under the car, and strong steady gas drip in front of drivers side rear wheel. . Several fuel lines that were side by side. . . Close to muffler. . . Fuel definitely dripping from them. . . . . . Rolled car foward ahead of spill, and headed home. . . . Looked where we usually park in driveway and saw an 18 inch round gas stain on asphalt. . . . . . Never seen it before today. . . . . . Used car on the 3rd to pick up food. . . . . . Stain from sept 3rd. . . Was a mechanic back in the 70`s and 80`s. . . . And figured since the tank didn`t empty. . . . . The leak must stop after an hour or so, or until fuel pressure in the system falls to zero psi. . . . . . . I`ve had tons of issues with this car, and biggest p o s I`ve ever owned. . . . . . . Has 112k on it and few more years left. . . . . . Might not get sticker this fall. . . . . . . The cheap front mud flaps don`t protect the car, and the rocker panels have major corrosion. . . . . . . Front drive shafts don`t last very long, and had years of computer issues and overheating on disability. . 2 metal hips and spinal cord injury. . . . . I`m going to get under this tomorrow , and see if I can make a temp repair, with some fuel hose, and a couple clamps. . . . . . I`d park it on the lawn for the next few months, and try to get rides. . . . But daughter`s medical appts keep me driving almost daily. . G m should pay fair market value, and take these all back. . . . . Older cars have exhaust issues , and a gas leak very close by, and boom. . . I would bet many many have had this problem, and fixed it, not knowing it`s a design error. . . . Help. . . Please!!!.

3 Other Fuel System Tank Assembly problem

Failure Date: 07/28/2020

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.

As I was driving on a city street, the engine began to run rough and I noticed the odor of gasoline. I pulled over to check for the source of the odor and found fuel leaking from the bottom of the car and onto the road. This was an extremely dangerous condition, as I could not stop the fuel from continuing to leak. I found that the fuel supply line between the fuel tank and engine rusted completely through near the driver side rear fender well, causing the leak. The evaporative emission vapor line was rusted and leaking as well, resulting in flammable fuel vapors escaping.

I started the car to move it back to see how much it leaked, it was then that fuel began running out everywhere around my shoes, had 1/2 tank. I shut off the car, as it scared me. And low fuel light came on. It still sets I'm my garage now. I noted many!!! complaints about this same problem.

28 Other Fuel System Tank Assembly problem

Failure Date: 10/06/2014

Owner of a 2008 chevy Cobalt, recently started having a strong smell of gasoline in and around vehicle after driving and even after the car had sat over night. Had vehicle diagnosed and was told that fuel was leaking on top of the fuel tank. Upon research I found that there have been several recalls and many complaints for this exact problem, but recalls are only in certain states. I'm sorry Chevrolet doesn't take the safety of it's customers seriously as I no longer feel safe driving my young children in this car. Chevrolet please explain how being in a different state changes the fact that you made a car with yet another defective part yet you will not take responsibility for all the vehicles that you put it in???.
