2 days after filling my 2003 Hyundai Sonata w/gas the gas started running out of the tank. It has done this twice. At times the auto shut off at the gas station stops filling the tank before it is full. It acts like it has pressure in the tank is that possible?

The large hose from the filler neck to the tank may be kinked or collapsed, there is also a vent hose following the same route that could be the problem.
Try angling the gas pump handle at a differnt angle than just up and down, also try pulling the neck out during filling.... also if you have time go to the dealer and tell them and show service what is going on during filling, maybe they have a technique for filling.
I would take the car to your nearest Autozone and they can scan your computer for free, this has to be some sort of problem with your gas evaporitive system
Iown 02 hyundai accent gl 1.6l. Had the problem twice. I used to over fill the tank until I had to spend close to $550.00 USD. The problem is when we overfill the tank. the carbon canister gets clogged and it damages a sensor in the assembly called "DMTL". Thia assy is located under the rear driver side of the car to the left and rear of the fuel tank. Once I replaced the carbon canister, sensor and filter the problem went away. if you let it go for a long time you eventually start smelling gas inside the car after fill ups. Good luck.
no its not the vent.it is the restrictor for the nozzle for unleaded gas.(thinner/smaller then leaded) causing a back pressure when you are filling up.sorry but you will just have to fill up slowly like i do....
We have an "04 Suzuki Verona that does the same thing, we have found that it is not the station as much as it is the angle that the tank inlet is on. When you put the gas nozzle in, it fills with some air to replace the gas comming out of the nozzle. Unless you find a place that has a higher pressure pump, you are in a long and "Clicking Off" ownership when it time to pump gas. For the record, I have noticed that if I chose the lowest setting on the handle, the pump will ussually fill about $10 at a time. two or three of those, and its a done deal. Hope this helps you.
for the gas problem its the evap shut off solenoid located along the fuel lines. do not take out the check valve in gas tank it will not work thats what you get for buying a hhyundai next time get a GM
