G6 6-cyl

  • 65,000 miles
In August of 2013, I noticed a strong gas smell when standing towards the back end of my G6. The problem was a bad fuel pump. Mileage was ~58,000. A few weeks later, my car began stalling and the charcoal canister had to be replaced. It is now may, 2014 and I've had my car back to the dealership for fuel system related issues five times. They've replaced the fuel pump and charcoal canister a total of three times and they even replaced the gas tank during round three. After the most recent repairs, I get "check gas cap" messages on my radio console every time I fill up, my check engine light comes on and I have acceleration issues. I'm just waiting for it to stall on me again and I pray it doesn't happen again on an on ramp. All repairs are documented through the dealership. In April, both low-beam headlights began working sporadically and within a week, quit working completely. I went to a shop close to the office and paid $50 to have both low-beam bulbs replaced. After about three weeks, the driver's side bulb was out again. I returned to the shop and they took the head lamp out and showed me that the problem was in the wiring harness of the head lamps. The wiring had become so hot, the wire insulation had melted off and the wires are exposed causing a short and blowing the bulbs. I'm now concerned that the electrical issues are more widespread and could be contributing to the continued problems with the fuel system. The dealership has been great to work with, but if the manufacturing dealership can't resolve these issues, I'm not hopeful that my car will ever run correctly again. I feel I have a great looking, unreliable lemon that adds a great deal of stress to my life. I can't afford a new car and I hate that I don't feel like I can go very far from home out of fear of ending up stranded or I won't make it home before the sun goes down.

I started smelling very strong gas fumes when I was driving, also when car was parked. I have taken it to the Chevrolet dealership and they ran a diagnostic and said my cars fuel pump is cracked and the gas is evaporating onto my exhaust making my car dangerous. There has been recalls on the G5 model for the same reason but not on the G6. I am a single mom and can not afford the one thousand dollars for it to be repaired while I wait for GM to find that the same problem exists in the G6 models. The car makes myself and my daughter sick from fumes that are coming from the back seat area. Please help.

I noticed a gasoline smell sometimes after I would get out of my car. Now the smell is very strong. I am going to stop driving the car till I can get it fixed. I noticed there was a recall done on the Pontiac G5 for this same thing. GM needs to acknowledge that the G6 has the same problem and do a recall before someone is hurt or worse killed due to this hazard problem. My problem also is I do not have the money at this time to get this hazard problem fixed.

Ok so I started having issues starting the vehicle out of know where. Then I started getting bad when I smelled gas every time I drive and once its parked. I now can smell gas fumes as we drive sometimes. I drive this vehicle back and forth to work and my 2 year old child rides with me. I have concerns that my car might blow up or catch fire if a spark was to happen.

The contact leases a 2008 Pontiac G6. While turning a corner in the vehicle, the gas tank holder detached from the frame and was dragging on the ground. The vehicle was towed to the dealer and they added more bolts to support the gas tank. The VIN was unknown. The current and failure mileages were 2,400.
