Noticed a strong gas smell coming from rear of car for several days. Finally took car in for inspection. Mechanic said that the fuel pump modulator needs to be replaced. I've seen on several websites that the pontiac g5 has the same problem and were being recalled. Unfortunately I haven't seen anything about the pontiac g6. I believe that this is a serious issue with this car. Could you please investigate this. When parking the car in my garage the odor was quite strong and also a danger to me and my family. The car could have caught on fire as well as my house.

Started smelling gas fumes when I stopped the car, now I smell it whether I am driving or stopped. Took it to my mechanic and they determined that it was leaking from the top of fuel tank. They said it was either the plastic fuel line cracked on the fuel pump or the module. They said this has been a safety problem with the 2008 g6. I think this is a problem that should be taken care of by gm. This is a serious safety problem with these cars. Gm needs a recall on this matter. Gm has had recalls on prior years of the g6 with the same problem.

Fuel pump assembly port developed a crack, resulting in fuel leaking from the area. A very strong fuel odor was noticed when being driven or parked, with slight drips sometimes noticed on the garage floor. The odor was so strong that it was even noticeable in the living areas from simply entering and leaving the garage. If an ignition source were present, a vehicle fire could have occurred, a serious concern. My local mechanic inspected and repaired the vehicle, and believed that the vehicle should be part of a pontiac recall on similar cobalt, g5, ion vehicles, that they've seen the problem on before, but our VIN does not register as a recalled vehicle for this problem.
