Check Engine Light Flashing

The check engine light flashing in a 2020 Hyundai Santa Fe is an urgent warning: it often indicates a severe misfire or condition that could damage the catalytic converter or other major engine components if driven further. When you see a flashing light, reduce engine load, avoid hard acceleration, and bring the vehicle to Stevinson Hyundai in CO immediately for diagnosis. Our technicians use Hyundai-specific scan tools to capture live data and pinpoint ignition misfires, fuel delivery faults, or sensor failures that cause flashing. By addressing a flashing light promptly at our dealership you protect the catalytic converter — one of the most expensive downstream components — and preserve performance, emissions compliance, and fuel economy. We provide transparent estimates, OEM parts, and warranty support; remember that warranty-covered repairs must be performed at a certified dealership to remain valid. Check current service specials and schedule service right away to reduce immediate cost and prevent costly long-term damage.
