Check Engine Light Flashing

A flashing check engine light on a 2011 Hyundai Sonata often indicates an active misfire that can damage the catalytic converter or lead to unsafe driving conditions. If you see a flashing light, stop driving when safe and bring the vehicle to Coggin Deland Hyundai right away; immediate attention minimizes repair scope and expense. Our Deland service center diagnoses root causes—ignition coils, spark plugs, fuel delivery, or sensor failures—using factory diagnostic tools. We highlight available service specials and can discuss service financing to make urgent repairs manageable. Addressing flashing conditions quickly not only reduces parts and labor costs over time but preserves emissions systems and resale value. For prompt, warranty-backed repairs from certified technicians, schedule appointment online or contact our service team for same-day options.

2011 Hyundai Sonata Check Engine Light Codes

Common check engine light codes for a 2011 Hyundai Sonata include P0420 (catalyst system efficiency), P0133 (oxygen sensor slow response), P0171/P0174 (fuel trim issues), and misfire codes such as P0300. Left unaddressed, these codes can escalate costs: an oxygen sensor failure can reduce fuel economy and damage catalytic components, leading to expensive replacements; fuel trim issues cause rough running and poor MPG; misfires can ruin the catalytic converter if you continue driving, turning a relatively low-cost ignition repair into a major expense. At Coggin Deland Hyundai in Deland, FL, we prioritize clear diagnostics, OEM parts, and estimates that show immediate and long-term savings. Our technicians explain what each code means, outline repair timelines, and apply appropriate warranties so you leave with confidence. Take advantage of our transparent process, check current service specials, and schedule service to protect your Sonata and save over the life of the vehicle.
