Just bought a used 2020 Santa Fe SE at a Hyundai dealership, 28k miles. I think I have an issue with the Idle Stop/Go feature. I don't think it's working. When stopped at a light, the circled A shows up on the dash, but I can hear and feel that the engine is still running. In addition, the button at the shifter is also lit up at the same time! I thought the button was only supposed to light up after I manually push it so it'll stop working. Malfunction?
