Summary
TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN: OIL LEVEL PLUG (OLP) INSPECTION, AND OLP GASKET AND/OR ATF FILLER BOLT REPLACEMENT OR A/T REPLACEMENT (SC363) - This bulletin provides information 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/or ATF filler bolt, or the 8-speed Automatic Transaxle (A/T) assembly on certain 2025-2026 Kia model vehicles listed in the table below. Also, dealers are to ensure the oil level plug is tightened to Kia
’s factory specifications upon the completion of the inspection and necessary repair. The oil level plug in the subject vehicles may not have been installed properly during assembly. The oil level plug may be loose or detached from the 8-speed Automatic Transaxle (A/T) which may result in leaking automatic transmission fluid (ATF). A transaxle which is operated with excessively low ATF may become damaged over time.
