On a recurring basis, the warning lights come on for-??AUTO HOLD-?? and -??EPB-?? or emergency parking brake. Car continually beeps and gives warning until car is reset. During this time, the cruise control will turn off, causing safety issues during travel. Also, the other safety features seem to stop working during the time this warning is activated. Emergency stop, et cetera. Only activated when vehicle is operating under highway mph. Typically local roads with stops/starts trigger this issue. Mechanics have no idea what is wrong with vehicle warning. I see online that this is a common issues with Hyundai Ioniq. A possible recall is needed to investigate/fix this issue as local dealerships arent aware of a solution.
