Check Engine Light Flashing

The check engine light flashing on a 2013 Hyundai Sonata Hybrid signals an active misfire or an issue that could cause immediate engine or emissions damage.

At Stevinson Hyundai in Colorado, our certified Hyundai technicians prioritize flashing-light concerns and perform an expedited diagnostic to limit further damage. Acting quickly protects long-term reliability and can save substantial repair costs compared with delayed attention.

Choosing the dealership ensures warranty compliance — any repairs covered under warranty must be performed at a certified dealership — and provides documented service history to protect vehicle value.

2013 Hyundai Sonata Hybrid Check Engine Light Codes

Common check engine light codes for a 2013 Hyundai Sonata Hybrid include P0420 (catalyst system efficiency), P0130-series (oxygen sensor), P0300-series (misfires), and hybrid-system-related codes. If unchecked, a P0420 may lead to catalytic converter failure—an expensive repair that also increases emissions and reduces fuel economy. Oxygen sensor issues (P0130-series) typically cause poor fuel trim, increased fuel use, and potential damage to exhaust components. Misfires (P0300-series) can cause rough running, poor mileage, and risk of engine damage if left untreated. At Stevinson Hyundai in Colorado, we diagnose each code with precise OEM tools and explain the cost-benefit of repairs versus deferred maintenance. Our factory-trained technicians use genuine Hyundai parts and follow manufacturer procedures to maximize longevity and performance, often delivering immediate and long-term savings over repeated quick fixes. We encourage owners to schedule service promptly and to check available service specials to reduce out-of-pocket expense. Trust Stevinson Hyundai for clear estimates, certified repairs, and service financing options that help you maintain your 2013 Hyundai Sonata Hybrid without delay.
