Owner Narrative

My 2022 Kia Seltos is equipped with Idle Stop & Go (ISG), which shuts the engine off when stopped and restarts it when the driver releases the brake/presses the accelerator. ISG stopped functioning about a year ago (the engine stayed running at stops). I didn't think anything of it because the ISG had worked sporadically from the day I bought the car. (I purchased it new.) It began working again, sporadically, about a week ago. Since then, on 3 occasions, when stopped at a red light with the engine auto-shut-off via ISG, pressing the accelerator to proceed causes the engine to fail to restart as I accelerate, and the vehicle stalls. The dashboard displays a "Press Ignition Button" message. I lose power to the engine, and the vehicle stops accelerating, coasting briefly on momentum until I manually restart it via the ignition button. I have not confirmed whether warning lights were illuminated, as my focus was on regaining control. This appears consistent with documented ISG restart failures reported by other Kia owners online, suggesting a possible pattern rather than an isolated defect. I checked my VIN on NHTSA.gov; zero open recalls. Kia customer care was closed when I called (today is a weekend day). I plan to call on Monday for a diagnostic appointment. This is a safety concern because the stall occurs unpredictably at the exact moment of accelerating from a stop, particularly hazardous at intersections in traffic.
