Check Engine Light Flashing

A flashing check engine light on a 2014 Hyundai Sonata Hybrid signals an active misfire or a condition that can rapidly damage catalytic converters and other emissions components. This is a higher-priority alert than a steady light because unburned fuel entering the exhaust can overheat critical parts and lead to costly repairs. At Larry H. Miller Hyundai Peoria in Peoria, AZ, we prioritize flashing warnings and recommend you stop driving if safe, then contact our service center for immediate guidance. Our factory-trained technicians use Hyundai-specific diagnostic equipment to capture freeze-frame data and interpret hybrid-system events alongside internal combustion codes, giving you an accurate repair plan. We also detail cost projections and lifetime savings — repairing a misfire early preserves fuel economy and avoids downstream catalytic converter replacement. Check our current service specials for coupons that reduce out-of-pocket expense, and take advantage of our service financing to get urgent repairs completed now and pay over time. To protect your vehicle and avoid escalating damage, schedule service or call our service team for priority support.

2014 Hyundai Sonata Hybrid Check Engine Light Reset

Resetting the check engine light on a 2014 Hyundai Sonata Hybrid is straightforward when done correctly, but the key is fixing the underlying fault rather than simply clearing the code. At Larry H. Miller Hyundai Peoria we perform a full diagnostic scan, document codes, and communicate the recommended repairs before any action. Our technicians reset codes only after confirming root-cause repairs — this prevents repeated visits and unneeded costs. Dealer service ensures OEM software updates, genuine Hyundai parts, and warranty protection; remember, warranty-covered repairs must be done at a certified dealership to remain valid. Transparency is central to our approach: you receive an itemized estimate, explanation of immediate and long-term benefits, and options to apply current service specials. Because factory-trained techs often identify issues faster than independent shops, many owners see immediate savings and fewer repeat repairs over time. Ready to get it done?

2014 Hyundai Sonata Hybrid Check Engine Light Codes

Common diagnostic trouble codes for a 2014 Hyundai Sonata Hybrid include P0420 (catalyst system efficiency), P0130–P0167 (oxygen sensor circuit faults), P0300–P0304 (misfires), and hybrid-system sensor or inverter codes specific to the Sonata Hybrid powertrain. Left unaddressed, each can lead to progressively higher costs: an unresolved oxygen sensor can reduce fuel economy and foul catalytic converters; misfires can destroy catalytic components and harm drivability; hybrid system faults may reduce battery efficiency and cause costly inverter repairs. At Larry H. Miller Hyundai Peoria we emphasize local convenience and trust — our Peoria service center provides Hyundai-certified diagnostics, OEM parts, and technicians experienced with hybrid systems.
