This is a long shot but may help (I've never done it on a Hyundai). Stand outside of the car by the door that will not open. Either press really hard or thrust your hip into the door by the door latch (or any other type of impact you can provide), then try opening the door. If this does not work you may need provide a faster and harder impact (obviously next to the latch). When door opens, ensure everything is tight and don't close door too gently :)
