This logic error may affect the Kia Connect services: calendar, weather, sports, vehicle diagnostics, maintenance and/or Kia Connect services rendering these features inoperable.

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.
