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. …
