TSB_ENG2632026-08-28. Service bulletin. TECHNICAL SERVICE BULLETIN: MISFIRE CONCERN DUE TO OVERRUNNING ALTERNATOR DECOUPLER - This bulletin provides information to address unresolved misfire events on some 2020–2024MY Forte (BDm) produced from January 1, 2019 through September 30, 2024, and 2020–2022MY Soul (SK3) vehicles produced from November 1, 2018 through May 31, 2022 equipped with a Gamma 1.6L T‑GDI engine. In certain cases, misfire symptoms may persist after completing normal diagnostic procedures and replacing ignition‑related components (spark plugs, ignition coils, and fuel injectors). If misfire concerns remain after these repairs are performed, excessive torsional oscillation of the Overrunning Alternator Decoupler (OAD) pulley may be the contributing factor. This bulletin provides the procedure to replace the OAD pulley with the updated Overrunning Alternator Pulley (OAP) kit and associated damper components.
SST082_R12025-09-05. Service bulletin. This bulletin provides instructions to perform an engine vibration inspection using the Kia Diagnostic System (KDS) tablet on certain Kia engine/model vehicles. The piston oil ring(s) in certain Kia engines may, over time, damage the surface of the engine cylinder wall. This may lead to increased oil consumption which will eventually result in abnormal noise from the engine and/or illumination of the oil pressure warning light. The applicable vehicle may or may not have the Piston Noise Sensing System (PNSS) software installed at the time of an engine vibration inspection. The PNSS software may detect engine noise triggering a DTC P132700.
