The other day while driving down a mountain with a very steep winding road after 45 months mutes the DBC red light came on. The thing is the DBC was not active for the descent so I'm not sure why the red light would have been displayed. Is this light also displayed when the breaks are getting hot?

Warning light be good indication of control module seeing fault in 1 or more of the many circuits related to system operation..

Have Hyundai dealer do complete Fault Code search of all onboard modules looking for fault codes,, reason for complete search is all the modules tied together via CAN and share info for various operations..
