• It signals that the vehicle’s onboard computer detected a fault in the electric drivetrain, battery/charging system, thermal management, or a safety-related circuit.

What is the first thing to check when the check engine light comes on?

• Check the instrument cluster for any accompanying warnings (battery, charging, thermal warnings) and note any changes in range or charging behavior.
• Confirm the vehicle’s charging connection and 12V system status—many EV warnings originate from accessory or 12V faults rather than the high‑voltage battery.
• Do not ignore a flashing light; if the light flashes or the vehicle shows limited performance, stop driving and contact Nalley Kia for immediate diagnosis.
