Ok Thanks for the VIN, This definitely helps.
It appears that you still have remaining basic warranty, have you taken it to the dealer yet for this concern? It sounds like you may have an issue with the audio output. After a bit of research, I found a couple service bulletins for the audio system. These updates can be performed at the dealer or if you have a 4gb usb memory stick, you can perform the updates yourself, there are 2 updates, one for the NAV and one for the radio.
Here are links to view the service bulletins:
Here is the link to download the software and instructions for performing the update.

Keep me posted on how it goes and let me know if you have any additional questions...
If these updates don't help, I recommend to take it to the dealer and have them look at it. It IS still under warranty and it won't cost you a dime to have it repaired...
