TSB_ELE382_R1	2025-10-24. Service bulletin. TECHNICAL SERVICE BULLETIN: IBU LOGIC IMPROVEMENT: This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to upgrade the Integrated Body Control Unit (IBU) software on some 2021-2025MY Seltos (SP2) vehicles produced from November 20, 2019 through January 13. 2025. When the key fob is stored near the vehicle, a signal generated by the IBU for the 'Welcome Function' can cause the key fob battery to become depleted. The ‘Welcome Function' is a convenience feature that activates certain features controlled by the IBU including the puddle lamps (if equipped) when approaching the vehicle with the smart key. By upgrading the IBU software, the ‘Welcome Function' feature prevents the IBU from continuously signaling the key fob after five (5) minutes, improving the key fob battery life.
SST082_R1	2025-09-05. 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.
