NHTSA — Fuel/Propulsion System Problems

2009 Pontiac G6 (Page 1 of 2)

CarComplaints.com Notes: The 2009 is starting to have the same problems as previous model years, including the headlights blowing out due to bad connectors.

The wiring harness connections aren't a big deal to replace, as long as your dealer or mechanic doesn't charge you an arm & a leg to "diagnose" the problem.

Strong smell of gasoline noticeable from 10 or more feet away from vehicle when parked or running. Cannot park in garage due to strong fuel smell. Vehicle has not been overfilled. Smell has been noticeable for many months but is getting stronger lately. Researching this on the internet yields many results with similar complaints, focused on a defective elbow on the fuel pump assembly.

Strong fuel smell and takes longer to turn over. Plastic hose on top of fuel pump cracked requires entire fuel pump to be replaced. Similar issue that required recall of previous years.

Have a gas odor coming from my car. When trying to start the car in the morning it cranks slightly longer but if I just turn the key on and wait a few seconds it seems to build up fuel pressure and cranks right up.

Strong gasoline smell from the car after driving. Suspect the fuel hose or fitting from the fuel pump is leaking gasoline on top of the gas tank. The fuel pump connector is right next to it and it could ignite the gasoline!

Noticed a strong smell of gasoline coming from the rear of the vehicle, most notably in the trunk. Online searches have noted that it is likely a cracked elbow on the fuel pump module that feeds the fuel lines. Odor has steadily increased over the past month.

I have a gas odor coming from my car and was informed by my mechanic that there is a gas leak coming from the top of the gas tank. I could see when it was on the lift signs of leakage to the botom of the tank. When trying to start the car in the morning it cranks slightly longer but if I just turn the key on and wait a few seconds it seems to build up fuel pressure and cranks right up.

I have noticed a odd gas smell in my car around 60,000 miles. I thought it was the gas cap, so I replaced it and the smell persisted. I had my car diagnosed by both a GM and a Firestone technician and they concluded it was a cracked fuel pump. It seeps gas out under my vehicle and if there is an ignition source I could blow up and die. Knowing of the severity of driving the vehicle I am scared to death to drive it. I haven't driven it in 2 months since it has been diagnosed. My family didn't want me to drive home for thanksgiving because they feared my car would hurt me. The GM dealership did not offer to fix it for other than full costs even when there have been several similar models and the Pontiac G5 also had a recall on the cracked fuel pump for 2009S. GM uses the same parts in their cars especially the plastic part that is prone to crack in the fuel pump, so I don't know why they haven't recalled the cars yet. It started at 60,000 miles. It is atypical of a car to have a defect at that young of a age, it can't be due to normal wear and tear. I have contacted GM directly several times and they keep shutting me down and have even tried the dealership and all they want to do is make money off me and they don't realize this is a serious issue here and lives could be at stake.

Started noticing a prominent gas smell everytime I pulled my daughter out of the back seat. I lokked underneath the car and noticed a drip, took the car in to a local shop and they found the fuel line ruptured. I found a GM campaign number 12190, the dealer said I am not covered. I bought the vehicle in ca which is one the states that such campaing mentions to be covering. The smell is very noticeable after placing the ignition in acc, which primes the pump I assume, if the car has been sitting for a few hours or overnight the smell is gone. I believe that my VIN should still be covered by GM as this is present a fire hazrd and potential for serious injury.

Started smelling fuel on exterior of the vehicle, most prominently near the gas tank. Took it to the dealership and found that the line connected to the fuel pump was corroding and fuel was leaking. They will have to replace the entire fuel pump module, as parts are not sold separately. The mechanic said that these are known issues with Pontiac. Did a little digging and found that there were over 40,000 recalls on GM products with this same issue, however, for some reason the 2009 Pontiac G6 did not make that list. Apparently we need some more complaints to get GM to add the G6 to the recall list (as leaking fuel could be a fire hazard!!!!).

  • 81,000 miles


On 4/7/15, while driving heard chimes. All icons on instrument panel turned on. The fuel gauge needle moved to empty. The low fuel gauge turned on. All this indicating malfunction. The odometer turned off and the code error came on and turned off; then the odometer came back on. All the icons on the instrument panel turned off except for the security light icon which stayed on. It felt as if someone was attempting to disable my vehicle. Later that day turned the vehicle on and everything seemed normal, like it reset itself. On 4/8/15, after driving approximately 70 miles on the highway, the security light icon turned on and stayed on. I took the vehicle directly to the dealer and they informed me they would have to diagnose the vehicle. The result was inconclusive, they did not find anything wrong. So not only was I put in an unsafe condition, this end up costing me $140 just to tell me they could not find anything - not only am I in the hole for $140 but I am back to square one. I feel GM should foot this bill as a customer courtesy due to the predicament this vehicle put me in. This should never have happened to a vehicle that is 6 years old and 80,000 miles.

I was driving up an incline on I-287 in NJ when my RPM's skyrocketed and by car's check engine light came on and my traction control light as flashed. My car began losing speed and became hard to control due to a loss of traction. Upon a visit to my mechanic it was found to be my catalytic converter. I have looked online and discovered the G6 from 04-10 have been known to experience this problem but yet GM has failed to make a recall. I would appreciate if you could look further into the situation. I was fortunate to be able to get my 4 way flashers on and avoid an accident narrowly. If my car had stalled like some of the other people I have read about who have had this problem it could have been fatal.

The gas tank on this 2009 Pontiac G6 GT is leaking fuel. Car was taken to dealer, dealer said that the fuel pump located in the gas tank needed to be replaced as it is leaking. Further investigation using non GM auto repair shops, I found this problem was not only on the G6 but many of the GM vehicles from 2005 to 2009. I believe that GM should issue a recall immediately due the fuel leaking from tank and splattering onto the hot exhaust system. At this time I'm not aware of any deaths related to this problem but will continue my research. This is my 24 year old niece's car. I'm her uncle.

My 2009 Pontiac G6 has gas fumes coming from it. I been reading online and found numbers of problem's with this. With all the people having problems with this I think GM needs to solve this problem before someone get hurt or killed. Please take care of this problem and have it recalled.

G6 4-cyl

  • 75,000 miles
Vehicle started smelling of gasoline with no apparent leaks. The motor had begun to run roughly and did not start immediately upon turning over. Not long after, gasoline began to drip from the heat shield below the fuel tank. Upon removal of the fuel tank, it was found that gasoline had pooled on top of the tank and was leaking from a cracked fuel line elbow directly above the fuel pump. Upon removal of the tank, the line broke completely from the pump.

I bought a used 2009 Pontiac G6 with 90,000 thousand miles on it. I have had it for a 1 year and 2 months before I started having problems. It all started message saying "check your gas cap". I would pull over and check gas cap it was vaporized. I opened and reclosed this was about 5 minutes from my house it takes 15 minutes to get to from house to town. Within 10 minutes my gas tank would wad up like a plastic bottle and when I would turn car off at work you could hear it un folding. This went on for 2 days then on the 2nd time my check engine came on I called and took to a dealership close to me. They told me it was the carbon canister it was going to cost $700 to fix. I did not have the money so I drove for a few weeks longer then my car was die when you go to stop at red lights or slow down. Both times semi trucks were behind me. The second time it did I called my husband crying said I was too scared to drive my car with me or my son in it. So I called the dealership where I bought the car and took to them to be fixed this was in September. They kept the car a week changed carbon filter and fixed speed cable this was making the car die. I got my car back drove from dealership and started to drive home when I noticed car still not fixed it was saying I had no gas so put gas in and it said I had 183 miles worth of gas by the time I got home I had 134 miles of gas left. I had called dealership to let them know that something was not right so in less then 24 hours took my car back to dealership and they kept it a week saying gas tank need to be replaced so they replaced it and replaced carbon filter again. Now the car works fine just wandering how long before it acts up again. I called Pontiac headquarters in all this time and they told me there was no recall and that there was nothing that they can do to help with the problem because I did not have any warranty.
