Check Engine Light Flashing

When the check engine light is flashing on a 2010 Hyundai Sonata it usually indicates a severe misfire or condition that could damage the catalytic converter or other critical components. A flashing light requires immediate attention: continued driving can escalate repair costs and shorten engine life. At Larry H. Miller Hyundai Albuquerque our certified technicians will perform a rapid but thorough diagnosis using OEM-level scanners, then explain repair options and costs clearly. We emphasize transparency and long-term savings—fixing the root cause early prevents cascading failures and often costs less over time than repeated patch repairs. We use genuine Hyundai parts and follow factory repair procedures so warranty coverage remains intact; note that warranty-covered work must be completed at a certified dealership to stay valid. If you see a flashing light, minimize driving and schedule service right away. Also check our service specials to offset repair costs, and ask about service financing to get repairs completed now and pay later. Protecting your Sonata now preserves reliability and resale value.
