The contact owns a 2007 Pontiac G6. The contact stated that while attempting to start the vehicle, the vehicle was difficult to start. Additionally, there was an abnormal fuel odor after driving and parking the vehicle. The vehicle was taken to an independent mechanic where the failure was undetermined; however, the mechanic was aware of the fuel odor. The dealer was not contacted. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 59,000.
I bought my G6 in 2022. After about a year of having it, issues started happening. Everything was fine up until my passenger side airbag warning appeared on my radio screen and it won't go off. Could be a serious issue with the airbag. Maybe around the end of 2023 I started having problems with my power steering. I could drive down the road and all of a sudden my steering wheel would lock up. I could barely get myself to a spot to get off the road. I had to force the steering wheel to turn. I shut the car off for a minute or so just to see what would happen. After I turned the car back on the steering cleared, but as soon as I decided to go back home it locked back up. Now it's starting to lock back up this year. My major issue I have is the gas smell that's coming from the car. The smell is so strong, it's coming inside the car. …
Electrical issue with my pontiac g6 I have had to replace my headlights bulbs multiple times due to the plugs melting I have actively seen the plug smoking and it has happened on both of my drl/low beam headlight bulbs resulting in plugs having to be replaced multiple times as well. My engine light isn't working and yet I have engine codes my service air bag light comes on at random my buckle seat belt light won't go off it stays on when I'm buckled in the driver's seat. My pressure sensor on my fuel tank has low voltage issues. When shutting the car off and opening the driver door all accessories that should of shut off are still active including the radio. The oil light is always turning on but the vehicle isn't low on oil nor does the message appear. When plugging in a car scanner the anti theft system light turns on and at random times will shut the car off. …
The contact owns a 2007 Pontiac G6. The contact stated that while driving at undisclosed speeds, there was a gasoline odor coming from the vehicle. The odor was also outside the vehicle. The contact became aware of a fluid leak underneath the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, and a fuel leak was confirmed. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 13E043000 (Fuel System, Gasoline, Equipment). The manufacturer was notified of the failure and informed the contact that parts were not purchased from the manufacturer, so the VIN was not included in the recall. The failure mileage was unavailable.
i was driving my car and stopped at a stop sign and my car shut down could not get it to turn back on at all had to get it towed to my apt then get it towed to a mechanic he said it was the starter and said it will continue to turn off untill the throttle body and map sensor are fixed also said 8f i turn my ac on it will turn off because something about the valve broke I'm not sure what that meant but i only had the car not even 3 months I spoke to the car lot who sold it to me and he told me i would have to pay for it and i don't have that kind of money i spent $3500 for the purchase of the car not so it can brake down 2 months later
The plastic hose that comes off the fuel pump cracked causing fuel to leak out of my car and very strong gas Vapors inside of my car. The smell of gas inside my car was so strong it literally made me sick not to mention gas leak in everywhere is never good. There was no light sensor or anything that come on to give any warnings still no lights on no check engine no nothing just fuel sausage and the smell is how I discovered it also there are many others with the Pontiac G6 GT they have the same issue which is why we are trying to report it to y'all as a safety concern
Bad fuel leak , location from top of fuel cell, Definitely from the fuel pump area of the top of the tank. Can't drive because it leaks so bad that fuel is dropping on top of the exhaust pipes and I am afraid of a fire any time driving the vehicle.i really like the vehicle but can't drive it because of safety reasons. What now? I have read of other G6 Pontiacs having recalls done so why isn't my vin. Covered the same way? I am very concerned about this leak and for others with the same , considering that it is high risk for loss of life...
Headlight went out . Upon changing it I noticed that wiring harness was burnt and melted. Also was driving and power steering went out driving 65 miles per hour. The cruise control got stuck . Right side making horrible noise at times. This has put me and my five year old as well as anyone driving near me at risk of dying.
When I visited a reputable brake shop for a brake check, it was discovered that my vehicle had a gasoline leak near the exhaust pipe. I took my vehicle to another brake shop which dropped my gasoline tank, only to discover that my vehicle had a leaky fuel pump. Before this brake shop worked on my vehicle, the mechanic told me that he was almost sure that the fuel pump had been recalled. I proceeded to go to brian harris Chevrolet, where the service manager checked my VIN number, only to inform me that my VIN number did not have a recall on the fuel pump. I was told that general motors would reimburse me for the fuel pump replacement, even if it was not replaced at a dealership, if the fuel pump might be recalled in the future. I went back to the other facility for the fuel pump replacement as a result. …
I have replaced the alternator, the electric power steering assist motor and air filter on multiple occasions and, after doing some research, have found that my car is experiencing every issue th's to have seen in previous GM vehicle safety recalls. Unfortunately, my VIN number seems to be one of those that has not been identified has having had those issues although it currently is experiencing them. I want to lodge a complaint that the VIN number search tool is not accurate enough to determine the validity of a claim. I say this because even on the NHTSA website, the tool says that not all VIN numbers that are experiencing issues with a recall have actually been associated to any recalls. As there do exist current recalls for all 07 Pontiac G6 models, there are no recalls related to my specific VIN number. …
