Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Kia Niro EV?

• Sensor or module issues: battery management sensors, inverter or motor sensors and wiring faults are common on EVs and often trigger the light.
• Software updates: control module calibrations or EV software bugs can generate codes until updated by a dealer.
• Charging and thermal systems: faults in charging hardware, coolant temperature sensors or battery thermal management may illuminate the light.
• Accessory or 12V system faults: low 12V battery or accessory failures can indirectly cause warning lights.
• Prompt dealer diagnosis prevents escalating damage and higher repair costs; warranty repairs must be performed at a certified dealership.

What does it mean when the check engine light comes on in a 2025 Kia Niro EV?

• It means the vehicle’s control unit has logged a fault code; severity ranges from advisory to critical depending on the system affected.
• For EVs this often relates to battery management, inverter/motor systems, charging circuits, or software communication errors.
• An illuminated steady light usually allows limited driving; a flashing light signals serious faults—stop and seek service immediately.
• Certified diagnostics at our dealership identify the exact code, saving you time and money by addressing the root cause quickly.

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

• Check the instrument cluster for additional messages or warnings and follow any safety prompts before continuing to drive.
• Confirm charging equipment and connectors are secure if you had just charged; a poor connection can trigger errors.
• Note recent events (noise, loss of power, charge anomalies) and capture them for the technician — it speeds diagnosis.
• Contact Courtesy Kia of Brandon to schedule a dealer-level scan; repairs covered under warranty must be done at a certified dealership.
