Frequently Asked Questions

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

• On a 2022 Hyundai IONIQ 5, first confirm whether the light is steady or flashing — flashing means stop driving and seek immediate service.
• Check the charging cable and connector: ensure the plug is fully seated and the charge session completed correctly.
• Verify the 12V accessory battery state — a weak 12V can trigger warning lights even on EVs.
• Look for recent software update messages or disconnected accessories; a simple restart or safe pull-over may protect the vehicle.
• If anything is unclear, contact Nalley Hyundai for certified diagnostics; warranty-covered repairs must be performed at a certified dealership.
