Sounds like a kinked hose to me. Or maybe the carbon canister is full of gas. Have you ever "topped off" the tank? That can force gas into the carbon canister.
The last recall by Hyundai on the 2008 Sonata was 18 months ago, for the OCS. I'd think those cars would have been fixed by now.

I have the sAme problem with my 2002 sonata, it takes forever to fill up the tank. A mechanic friend if mine checked it and tried to fix it, it seemed that the carbon canister broke and the tiny pieces of carbon got stuck inside the ducts, This part in which the gas goes through looks like a saxophone, my friend took it apart and we saw all the carbon pieces coming out of it, but i guess we did not removed the one that was stuck, he said there is a way around this fix, to make the gas go straight to the tank, I wonder If a repair shop would do that and how much will it cost to fix.

It seems as if this "workaround" would disable part of the car's emissions control system. If so, I don't think a reputable shop would do that kind of thing. Might even be illegal to do that... not sure about that. I'd also be wary of any kind of "workaround" involving the fuel system from a safety standpoint.

Sounds like the there might be a problem with the fuel vent canister. Any lights, codes? When you fuel up, do you hear any venting when you remove the gas cap? Leave the gas cap off after starting and see if you continue to have the same problem.
Report back with the results.

There are no codes, no venting when removing the cap and i tried leaving the cap off after putting gas in and it did the same thing.

Get a K & N air filter. Don't know exact figures on gas mileage but getting 32 MPG on my 2009 Hyundai Genesis (Hwy mileage) with the new filter. About 4 MPG higher than factory specs and you will probably notice a little more Horse power. Will pay for itself quickly with gas prices now.

The question is, did the car CONTINUE to have the same problem as you drove it multiple times with the gas cap off? I believe that you previously stated that the problem previously occurred only on the first drive after a refill when the gas cap was in place.

I didnt drive it around with the gas cap off did you want me to do that? yes it only happens on the initial start after fueling and it is good after that.

Yes, I'd like to confirm the problem is caused when the gas cap is removed to fuel the car. If the problem continues to exist as long as the fuel cap is off, that would be a pretty good indicator that the fuel vent system is compromised.
Does anyone have any other ideas or possibly a comment on my idea?
