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

• Verify obvious items: secure charging cable, locked charging port, and that the vehicle is in Park with adequate 12V charge.
• Confirm the instrument cluster message — some alerts identify charging or battery system faults that require immediate attention.
• If you recently charged or plugged in, try a complete restart procedure described in the owner’s guide, but do not rely on a reset alone.

What is the most common reason for check engine light on a 2022 Hyundai Kona Electric?

• Common causes on EVs include battery management system alerts, inverter/charger faults, or thermal-management issues affecting range and performance.
• Charging port communication errors or faults with the DC‑DC converter can also trigger the light without indicating engine problems.
• Ignoring these signs can reduce range, accelerate wear on high-voltage components, and lead to costlier repairs later.
• We recommend dealer diagnostics to identify root causes quickly; Nalley Hyundai’s EV-trained technicians use OEM tools to protect warranties and save you money over time.
