Around 127000 miles I noticed a strong smell of gasoline, and a small drip from under my car, after taking a closer look I noticed that it was gas, and it was coming from the retaining clip that holds the fuel/brake lines in place, I was not financially stable to have this repaired at the time, and it wasn't leaking to bad so I left it go, after about 2-3 more weeks I was driving and noticed that I could literally see my fuel gauge dropping, I immediately pulled over and inspected the problem area and see that the car was dumping fuel and a very high pressurized rate, I also took note that the gas was being sprayed onto the hot exhaust that is about 4-6? away from the fuel lines, I got the car home and parked it, after doing hours of research I seen that 95% of this year and model of GM have this issue due to the heat shielding on the fuel lines after searching my VIN it says that my vehicle has no active recalls but I've seen complaint after complaint about this issue, not only that it is extremely dangerous that gas is being stayed out under pressure which is causing it to vaporize and become even more of a fire hazard, not to mention it is inches away from the exhaust and directly below the fuel tank... this issue should defiantly be addressed with GM and be submitted for recall in my opinion, this issue only happens when the vehicle is on or the key is turned to the on position and the fuel pump is primed and running to charge the fuel lines, after the vehicle is turned off the leak stops after the fuel line has drained onto the ground causing another fire hazard and a environmental hazard making it an issue to start the car again due to no gas being in the lines, in my case I have to turn the key to on and give the fuel pump about 15 seconds to prime and pump gas into the lines, this issue has made it impossible to drive as I dump a gallon of fuel every 2-3 miles.

The contact owns a 2009 pontiact G5. The contact stated that while driving approximately 35 mph, the vehicle stalled multiple times. The vehicle was taken to an authorized dealer, who was not unable to determine the problem. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 100.

Car started smelling of gas. Then garage smelled of gas. Then the fuel economy became inaccurate. Then gas started dripping from under car. Then gas started streaming under car. Then told GM dealer and was told there would be no remedy until GM recalls take effect. Now, 8 months later no repair offered. Car is unsafe and leaves me stranded regularly as it pours gas out of car. I will take car back to dealer and expect immediate repair.
