I'm thinking it just needs to be topped off.

Voltage at battery posts, should be @ 12.5, check voltage at cable ends, should be the same, and voltage at starter same, but that's tough to do with the location of the starter.

Wont start, reset immobilization | Kia Forum
Oct 10, 2020 · The BCM connectors have been problematic in the past.
