2002 Hyundai Sonata 6 cyl Front Wheel Drive Automatic 89000 miles
for the last several month when ever I stop to fill the car up with gas it takes almost 20 min to fill the gas tank up. It doesn't matter which station I go to it happens at all of them. The gas starts going in then it clicks off no matter how you hold it. You might be lucky and get a gallon or two in before it clicks off again. It like the gas won't flow into the tank. Could a vent be plugged.
