- [11034847](https://open.wenmarpro.com/bulletins/11034847), 2026-07-08: Some Kona \(SX2\) vehicles equipped with the 1.6L T‑GDI engine may exhibit false “engine left idling” notifications in the MyHyundai app, even when the engine is not running, due to a logic error associated with the front oxygen \(O₂\) sensor. This condition may also illuminate the Malfunction Indicator Lamp \(MIL\) and set DTC P223700 \(O₂ Sensor Pumping Current Circuit/Open \[Bank 1 Sensor 1\]\). This bulletin provides instructions to perform an ECU software update to correct the O₂ sensor logic and resolve the condition.
