I have a 2009 Kia Rio, and I have had this same issue with gasoline gurgling back out of the tank after the pump clicks off. This is a problem I have had since I bought the car brand new almost three years ago. I even went with one of the techs from the dealership to the gas station, in the hopes that it would happen with a witness present, but alas, like the check engine light turning off as soon as you get to the mechanic, nothing happened (so I recorded the event on my phone and showed the tech that instead).

I have taken the car to the dealership about 5 or 6 times for this same problem over the time I have owned it, and they can't seem to figure out what the problem is. I think, and I am far from a professional, that it may not be venting correctly. Every car I have ever owned has small holes where gasses escape as you fill up. These holes were much larger in my previous vehicles, and I never had this problem before I purchased my Rio. The car does not spit up gas every single time I fill it up, but the chance is always greater if I let it get too far towards the E, although that is not always the case (I have had it spit up with half a tank of gas before).

At this point I am resigned to dealing with this problem until it is time to get a new car. It certainly will not be a Kia. A new car really shouldn't spit up gas when it is filled up, and I feel that some of the parts seem to wear out prematurely. Thank goodness for that warranty.
