Official summary
VOLUNTARY SERVICE CAMPAIGN: OWNER NOTIFICATION (SC363) - This document is the owner notification advising that Kia is conducting a Voluntary Service Campaign on certain 2025-2026 MY K5 vehicles to inspect the oil level plug and automatic transmission fluid (ATF) for signs of leakage and, if necessary, replace the oil level plug gasket and ATF filler bolt and ensure the oil level plug is tightened to Kia’s factory specifications. If necessary, the 8-speed Automatic Transaxle (A/T) may require replacement based on the inspection results.
Vehicles covered
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.
