Check Engine Light Flashing

The check engine light flashing on your 2013 Hyundai Sonata Hybrid is a sign of a severe problem—often misfires that can damage the catalytic converter and compromise drivability.

At Arapahoe Hyundai in CO our technicians evaluate both the internal combustion system and hybrid components using factory diagnostic tools. We prioritize safety and efficiency, performing a targeted inspection, identifying codes, and recommending corrective repairs that preserve performance and fuel economy. Choosing our dealership means OEM parts, factory-recommended procedures, and warranty-compliant repairs handled by certified Hyundai technicians. We also make service affordable: ask about service financing to get necessary repairs now and pay over time, and check our current service specials for added savings.

2013 Hyundai Sonata Hybrid Check Engine Light Codes

Common codes for the 2013 Hyundai Sonata Hybrid include P0420 (catalytic converter efficiency), P0300 (random/multiple misfires), P0135 (oxygen sensor heater circuit), and hybrid-related battery management alerts. Ignoring these codes can drive up costs: a failing oxygen sensor left unreplaced will shorten catalyst life and reduce efficiency, resulting in higher fuel bills and a catalytic converter replacement that can be thousands more than timely sensor service. Misfires can cause immediate damage to the catalytic converter and create unsafe driving conditions. At Arapahoe Hyundai in CO we provide transparent cost estimates and explain immediate and long-term savings from prompt, OEM-compliant repairs. Our service lanes are equipped for hybrid diagnostics, and certified technicians follow Hyundai procedures to protect your vehicle’s lifespan and warranty. We encourage customers to review our service specials and to schedule service for diagnostics—our goal is fast, accurate repairs that prioritize safety, economy, and reliability.

2013 Hyundai Sonata Hybrid Check Engine Light Reset

Resetting the check engine light on a 2013 Hyundai Sonata Hybrid can be done after addressing the underlying issue, but a simple reset without repair won’t fix the cause and may lead to recurring faults. At Arapahoe Hyundai we recommend a full diagnostic and repair before clearing codes to ensure the problem is resolved permanently. Our technicians use OEM tools to read pending and permanent codes, repair components with genuine Hyundai parts, and then verify repairs with test drives and follow-up scans. This transparent approach protects your warranty, prevents repeat visits, and often costs less in the long run than piecemeal fixes. We also provide service financing to help you complete necessary repairs now and pay later, plus rotating service specials to reduce out-of-pocket expense. To protect your vehicle’s performance and value, schedule service with Arapahoe Hyundai and let our certified team deliver reliable, long-lasting results.
