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 partially 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.

When trying to fuel vehicle the nozzle will click off at 1 or 2 gallons. I have to repeatedly take the nozzle out and keep trying to refuel. The vehicle was taken to the dealer in which they dropped the gas tank and did something. I picked the vehicle up and went to refuel and the same problem still exist. Just out of money. I see this is an on-going problem with this vehicle. There should be a recall.

Fueling problems. On near empty fuel tank the fueling hose will auto shut off after 1 to 2 gallons. I have to repeat start the fueling and it automatically shuts off after entering a gallon or two. Have to gauge when tank is near full which can cause a fuel spill if overestimating and not being fill if underestimating. It seems to happen at pumps that have the newer nozzle. This is the first summer for this problem and it may be caused by the heat with the newer nozzles..

As a result, the fuel system would need to be rebuilt. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 92,000 and the current mileage was 94,000.

One day, while fueling my 2003 Hyundai Sonata, the pump clicked off after 1 gallon. From then on, it wouldn't let me fill more than 1 or 2 gallons without clicking off. Since that day, this problem occurs every time I refill and every time my tank is near empty or half empty, so I know that's not the issue.
