I have had a problem with the audio going out on occasion in my Sonata Hybrid Limited 2012. I have figured out that the circumstances that create it are when I put the car into reverse before the computer warm up completes. By warming up I mean the LCD screen changes from the Hyundai symbol to the radio or map. If I make the screen jump straight from the Hyundai symbol to the back up camera, I can hear music but as soon as I put the car into drive I lose all audio for the entire trip in the car. I can only reset and regain audio by pulling over, turning off the car for 2-3 minutes and then restarting the car, essentially, a reboot of the computer. Dealership has never heard of this so I am having them do an analysis and call their tech support today. Has anyone else experienced this?
