Hyundai vehicles are equipped with Dark Current Control logic to help reduce amperage draw amount and conserve Battery State of Charge (SOC%). A selected Dark Current Control Mode will function when the vehicle is in the key off state, and will not affect vehicle functionality or performance.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
