Frequently Asked Questions

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

• Check basic items first: ensure the charging cable is fully connected and the 12V auxiliary battery has charge; low 12V voltage can trigger warning lights in EVs.
• Confirm no obvious charging interruptions, loose plugs, or visible damage to charging equipment before continuing to drive.
• Review the instrument cluster messages — some faults include clear prompts (charging fault, reduced power, or service required).
• If in doubt, stop driving and contact Courtesy Hyundai of Tampa for factory diagnosis; repairs covered under warranty must be completed at a certified dealership.
