Well it occured again: NO AUDIO! (x3 for my 2012, x 10 for the 2010 I owned). I read in the Equus section that one owner had this occur while near a Hyundai Service Center and he droped in while the audio was dead. He reports that the service writer knew of the problem and the solve: remove the interior, driver's side, big, yellow fuse for a moment and then replace it. I did and this works. Add this to a list of quirks we have to live with.
Did you get the TSB 12-BE-012-1 applied to your car?
