I have a 2016 Tahoe LT with 25k miles, with the Infotainment (I think that's the name) system. Recently, some of the touch buttons on the radio buttons have started randomly disappearing. If I hit the home button, and go back to radio, they show back up. Any thoughts about what could be wrong? Do these things get software updates somehow? See the pic below. The buttons I'm talking about are between the station info and the fav buttons.
