This may be an antenna issue, but no matter, I would take this to the dealer and see if they have run into this issue. It still may be under warranty as well. Make sure the dealer checks all technical service bulletins and other technical info from Hyundai regarding radio issues. Sometimes these things are fixed by adding new software to the vehicle, and this is best done by the dealer on a vehicle this new.
