Check Engine Light Flashing

The check engine light flashing on your 2020 Hyundai Veloster is a critical alert: it typically indicates an active misfire or another condition that can quickly damage the catalytic converter or engine internals.

Our factory-trained Hyundai technicians will perform a rapid but thorough diagnosis using OEM diagnostic tools, isolating ignition, fuel, and sensor-related faults that commonly cause flashing conditions. Beyond the immediate diagnosis, we explain repair priorities and how prompt service prevents cascading damage—which in many cases reduces the total repair bill and protects your vehicle’s long-term reliability.
