You have a Limited edition Sonata where the Treble Control on your PREMIUM INFINITY radio doesn't work! They don't work right in at least all 2018 and 2019 Limited models! Have you complained to Hyundai to get Infinity to issue a software update? The treble slider on display screen moves from -10 to +10, but there is no change in the higher-frequency sound! HYUNDAI and INFINITY should fix this! TERRIBLE QUALITY CONTROL!
