Check Engine Light Flashing

The check engine light flashing in a 2024 Hyundai Sonata is a sign of an active misfire or severe engine problem that can cause catalytic converter damage, reduced performance, or unsafe driving conditions. When you see a flashing light, pull over safely, reduce engine load, and drive minimally to prevent further damage. At Larry H. Miller Hyundai Peoria in Peoria, AZ, our technicians prioritize flashing-light cases: we perform an immediate diagnostic scan, inspect ignition components and fuel systems, and provide a clear plan of action. Prompt attention can prevent expensive downstream repairs—replacing a catalytic converter or repairing engine internals is far costlier than addressing ignition coils, spark plugs, or fuel delivery issues early. We also make repairs easier with factory-trained techs, OEM parts, and financing options so you can get back on the road without delay.
