Official summary
On certain 2018 MY Sonata (LF) equipped with the 2.4L or 2.0L Turbo engine, the starter M-Terminal nut may become relaxed and loosened. If this condition exists, the vehicle may experience a no crank condition in colder ambient temperatures. In most cases the starter will function normally at room temperature.

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.
