Kia Troubleshooting Questions? Ask a Mechanic
Hi. It is common for the radio display to go black and need a radio replacement on the 2015 Sorento. But first sometimes resetting the audio unit will fix the problem. I recommend you first go out and disconnect the battery cables from the battery. Then touch the cables together to drain all remaining voltage in the system. Then reconnect the cables and see if the audio unit display is back. Can you do that and let me know the outcome?
