Door newly out of plane - just winter weather or bad framing?
Most units are prehung. If the mortises on the jam and door look perfect and fit precisely, it is usually a prehung.  Unless the situation is intolerable, I'd give it a while and let conditions change before making drastic changes to the door or hinge sets. I suspect possible settling or drastic humidity or temperature  related expansion to the frame. You should also check to assure all the hung screw are snug. If you have a good 6 foot level, you can compare plumb between the door and frame on both sides to determine if a side has moved or lay the level against the door and look for any bow, gaps etc.   An other test is to remove the door (just remove hinge pins) and check that it has not warped by laying it on a known flat surface and look for gaps or rocking indicating that the door may have warped. Sometimes very hard to see a small wain by eye when hung.
