Summary
TECHNICAL SERVICE BULLETIN: 2.5L GDI THETA III ECU SOFTWARE UPGRADE FOR ISG OPERATION LOGIC - This bulletin provides information to upgrade the Engine Control Unit (ECU) software on some 2023MY Sportage (NQ5) vehicles equipped with a Theta III 2.5L GDI engine, produced from December 15, 2021 through July 17, 2023 and Sportage (NQ5a) vehicles equipped with Theta III 2.5L GDI engine, produced from January 12, 2022 through July 10, 2023, due to the possibility of an intermittent restart failure in rare circumstances with Idle Stop Go (ISG) enabled. The existing logic may prevent the vehicle from restarting automatically within a short time period (0.2 second) after entering "auto stop" mode and under certain engine and ambient conditions. However, if this occurs, the engine can be restarted by the driver after placing the gear shift selector to Park (P) or Neutral (N) and pressing the ENGINE START/STOP button.
