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.
