I have the same problem in my 2012 3.8. I've also confirmed Tompass's observation that after turning the ignition off, surround sound setting returns to off for all modes except the one that was currently in use. I wonder if Hyundai has a fix for this.
Actually my post states that selections for all modes, if checked, remain checked after turning off and restarting the car.
I wonder why surround is not the default "on" as I think it sounds better on all signal sources. I as well need to re-check the surround box as it defaults to the off position each start of the ignition. Conversly the treble / mid /bass & previous volume & source settings stay as I selected. IMHO I do not think it is a glitch, but just the way it is programmed. An update would be nice.
I had some of the same issues on my new 2012 R Spec. No voice commands, no Bluetooth and the surround sound would not stay on. See my thread from an earlier post.

I now have options for future editions of the Genesis. Very strange.
Thanks for the link Seattle. Did the new audio head unit solve your problems?
It just doesn't make sense to me that you would intentionally program a system that allows the user to customize many audio settings to his personal preference, then have one of those settings revert to a default each time you start the car. So I do think it is a glitch. My 2009 never did this. Perhaps it is just an issue in the 2012's.
