Frequently Asked Questions

What is the most common reason for check engine light on a 2020 Hyundai Kona Electric?

• Common triggers include sensor faults (oxygen, temperature, or coolant sensors), charging system irregularities, and battery thermal-management alerts specific to electric vehicles.
• Many issues start small — a failing sensor or loose connector — but can escalate to reduced range or charging problems when ignored.
• Catching problems early at Courtesy Hyundai of Tampa helps avoid costly repairs later; our diagnostics can often find and fix issues before they impact performance or warranty coverage.
• Remember: any repairs covered under warranty must be performed at a certified dealership to preserve coverage.

What does it mean when the check engine light comes on in a 2020 Hyundai Kona Electric?

• The light signals the vehicle’s onboard diagnostics (OBD) detected a system or component outside expected parameters — from emission sensors to EV powertrain elements.
• For electric models, it can indicate charging, inverter, motor, or battery management issues as well as standard sensor failures.
• It does not always mean immediate breakdown, but it does require prompt diagnosis to protect range and system health.
