Issue
The engine controller's control program is incorrect. After an idling stop, if the ISG (Integrated Starter Generator) fails to restart the engine, the protection function that switches to starter motor restart does not activate. As a result, the engine may not restart automatically.

On all vehicles, reprogram the engine controller's control program to the corrected/updated software.
