I purchased this car used. When I first purchased it, I smelled an strong odor of gas/fuel. When I researched the car on the internet, the search revealed there was a recall on the fuel system of the 2005 Pontiac Aztek. After reading more in detail about the recall, the search found that the fuel pressure regulator were produced without an o'ring and retainer, which caused the fuel to leak. I took my car to the dealership to be checked. They found that fuel was leaking and the fuel pressure regulator had to be replaced and the throttle body was choking. I contacted GM and I was told that because my VIN number did not read from an area that had recalls, I would not be helped in this situation. I responded that my car had the same issues as other cars. …

Since we first bought the car in 2005, whenever the fuel tank is filled to 3/4 or higher the car starts to smell of fuel fumes. If it is filled up full to the top, it literally spills fuel onto the ground (about 16oz). I called GM and they told me to bring it to the dealership. The dealership looked at it and determined that it is a bad weld on the fuel tank filler neck and also confirmed that the car is exhibiting the same symptoms as listed in multiple safety recalls regarding this fuel tank. The vin of this vehicle is within the range of safety recall bulletin number 06230, and is exhibiting the exact issues mentioned in that bulletin, but GM is saying that the specific vin is not included and that I need to contact NHTSA to have my vin added before they will fix it. The car only has 130,000 miles on it and this has been an issue for over 17 years. …

I recently borrowed my mother-in-law's vehicle. When I returned to my home I parked in the attached garage. Later, when my daughter came home she asked why it smelled like gas. I went to check and upon entering the laundry area (directly attached to the garage via access to the house) I noticed the smell. I inspected the garage and thought, perhaps, the smell was coming from a weed wacker. Later, I went to check on some laundry and the gas smell was even worse. I opened the door to access the garage and then recalled the weed wacker was actually broken and was only there to be discarded in the trash next pickup. I was concerned and went and woke my husband saying I smelled over-powering gas smell and to please come check. He indicated he thought it May be his mom's car. …

Fuel tank filler sprayed fuel onto exhaust pipe while under normal interstate driving conditions. My wife smelled an electrical burning smell about 10 minutes prior to the fire while fueling at a service station. She dismissed it since there was a nearby construction crew that was burning trash in barrels. She thought perhaps it was something they were burning. After a visual inspection of the vehicle, we continued on.
