2018 Sportage LX - ABS, Traction Control, and Downhill brake(?) lights came on

[jamesandrew]

Can anyone tell me why these lights would come on randomly. It was fine this morning, I parked for an hour and came back and these lights stayed on after the system check. No warnings on the LCD display and according to the Torque app on my phone, no codes in the ECU. I am at a loss as to why these lights would be on. Everything drives normally, brakes function normally, etc.
