Check Engine Light Flashing

A flashing check engine light on a 2025 Hyundai Tucson typically signals a severe misfire or condition that could damage the catalytic converter if driven. It’s a higher-severity alert than a steady light and means you should stop driving and have the vehicle inspected immediately to avoid costly downstream repairs. At Larry H. Miller Hyundai Peoria our certified technicians perform priority inspections for flashing lights: we check ignition coils, spark plugs, fuel delivery, and the exhaust system to identify root causes. We offer transparent estimates, OEM parts, and manufacturer-backed warranties—repairs under warranty must be done at a certified dealership to remain valid. Take advantage of current service specials and ask about our service financing to get safe repairs done now and pay over time. Schedule a prompt evaluation via our schedule service page or call the service center to reserve a time; rapid action limits damage and keeps ownership costs lower over the life of your Tucson.
