## Other bulletins for the same vehicles and component

- [SST082\_R1](/bulletins/11022844.md), 2025-09-05, Service bulletin: ENGINE; ELECTRICAL SYSTEM. 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.
- [SC336YZ\_TSB](/bulletins/11022843.md), 2025-09-05, Service bulletin: ENGINE. This bulletin provides information related to the Technical Service Bulletin previously published under SC336 titled “Engine Inspection/Replacement and ECM Logic Improvement”.

- [TSB\_ENG239](/bulletins/10214889.md), 2022-07-02, Service bulletin: ENGINE AND ENGINE COOLING. TECHNICAL SERVICE BULLETIN: DATA COLLECTION: EXTRACT CALIFORNIA EMISSIONS DATA FROM ECU \(DC23\) \- This bulletin provides information related to extracting in use performance tracking emissions data from the Engine Control Unit \(ECU\) of certain vehicles sold in California. The California Air Resources Board \(CARB\) requires the emissions data from vehicles with a minimum of 3,000 accumulated miles without reprogramming or resetting. To facilitate collection of this data at the dealer level, KDS screenshots will allow the capture of relevant parameters.
