Other Fuel System Tank Filling/charging problems of the 2003 Hyundai Sonata

Like many other complainants, for the past month, I have experienced problems filling up my gas tank. After only 1 gallon or less, the pump automatically shuts off as if the tank is full. It has taken me approximately 10 minutes just to put 1/4 tank of gas in my vehicle. When this first happened, gas overflowed and spilled on my shoes, my car, and the ground. Thinking there was a problem with the gas pump, I went to a different gas station and had the same problem. In viewing forums throughout the internet, this appears to be a problem that's been ongoing for several years now for this car model. It is a safety hazard due to the potential for gas to overflow onto a person and the outside of the vehicle, which could lead to a fire under certain circumstances.

I was informed this model has a safety valve in the gas filler neck that will prevent the gas from leaking out should the vehicle overturn. My valve must be stuck in the paritally open position since I can only fill the gas tank every one-third of a gallon before the gas dispenser shuts off. Then I have to wait 10 seconds for it to seep into the tank before I can continue to pump. Filling my 17 gal tank takes about 10-12 minutes with most of the time just waiting for the gas to seep into the tank. Hyundai wants over $600 to repair. Unacceptable since it appears to be a design flaw.

You can not fill gas tank pass half with out the smell filling the car . The back suspension when you go over 40 tales from side to side . The car was on the highway .
