Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Hyundai IONIQ 5?

• High-voltage system alerts—battery thermal management or charging faults are common on EVs and trigger the malfunction indicator.
• 12V accessory or sensor faults can also illuminate the light though the main drive system is unaffected.
• Software or communication errors between modules (CAN bus) are frequent and require dealer-level scanners to diagnose correctly.
• Addressing issues at Coggin Deland Hyundai often costs less than independent shops, while providing factory-trained technicians, correct software updates, and warranty protection.
• Remember: repairs covered under warranty must be performed at a certified dealership to retain coverage.

What does it mean when the check engine light comes on in a 2025 Hyundai IONIQ 5?

• It indicates the vehicle’s onboard diagnostics detected a fault in the powertrain, battery management, charging system, or emissions-related systems for hybrid variants.
• Some alerts are informational; others indicate reduced performance or immediate risk to components.
• Only a diagnostic scan with OEM tools at a dealership will reveal the specific trouble code and recommended repair path.
• Coggin Deland Hyundai’s factory-trained technicians interpret codes accurately and apply software updates, saving you money now and preventing costly downstream damage.
• Warranty repairs must be completed at a certified dealership to maintain coverage and ensure proper procedures.

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

• Safely reduce speed and check for immediate drivability changes—any loss of power or unusual noises warrants stopping and calling for assistance.
• Verify charging status and connectors if the vehicle was charging; improper contact or interrupted charge can trigger alerts.
• Check 12V systems and visible connectors; a weak 12V battery often causes electronic faults on EVs.
