Check Engine Light Flashing

A flashing check engine light on a 2026 Hyundai Elantra indicates a more urgent issue — often a misfire that can damage the catalytic converter or signal an electrical fault. When you see a flashing light, pull over safely, reduce load on the engine, and contact Larry H. Miller Hyundai Albuquerque for immediate guidance. Our dealership prioritizes these calls: we perform rapid scans using OEM diagnostic tools, isolate the cause, and present clear repair options. In some cases, battery problems or poor charging can create erratic sensor readings; our battery testing and replacement services quickly verify whether the battery or alternator contributed to the fault. Taking prompt action reduces repair costs over time and protects your vehicle’s emissions system. We also highlight available service specials and offer service financing so you can address urgent repairs without undue delay. For peace of mind and certified repair, schedule service online or contact our service team at Larry H. Miller Hyundai Albuquerque.
