Check Engine Light Flashing

The check engine light flashing in a 2023 Hyundai Santa Fe Plug-In Hybrid signals a severe condition that needs immediate attention. A flashing light typically indicates a misfire, which can damage the catalytic converter, reduce fuel efficiency, increase emissions, and in hybrid models put extra strain on battery and power-management systems. At Larry H. Miller Hyundai Peoria in Peoria, AZ, our priority is to protect your vehicle and minimize repair costs. We begin with a rapid, factory-grade scan to capture stored codes and live-data readings, then perform targeted tests to isolate misfires, ignition issues, or fuel delivery faults. Because catalytic converter repairs and hybrid battery repairs can be costly if delayed, acting quickly saves money now and prevents larger, long-term expenses. We invite you to review current service specials and schedule service online for expedited attention. Our certified Hyundai technicians will explain findings, provide an estimate, and discuss service financing if you want to spread payments. Trust our trained team for a prompt, transparent repair that protects system warranties and extends vehicle life.

2023 Hyundai Santa Fe Plug-In Hybrid Check Engine Light Codes

Common check engine light codes on a 2023 Hyundai Santa Fe Plug-In Hybrid often involve O2 sensors (P0130–P0167 range), catalytic converter efficiency (P0420), EV/hybrid system sensors, and misfire codes (P0300–P0312). Each has associated risks and costs if ignored: faulty O2 sensors can lower fuel economy and damage the catalytic converter; an unchecked converter fault can result in five-figure repairs; hybrid-sensor faults can limit electric drive range and affect charging. At Larry H. Miller Hyundai Peoria we focus on accurate code interpretation to avoid unnecessary parts replacement. Our process includes OEM diagnostics, prioritized repairs, and clear communication about expected costs and timeline. Choosing certified dealership service not only protects your factory warranty (warranty repairs must be completed at an authorized dealership) but often costs less in the long run due to correct, first-time repairs and genuine parts. We also provide service financing so you can get necessary work done now and pay over time. To minimize downtime and get transparent pricing, schedule appointment today and check our service specials for additional savings.

2023 Hyundai Santa Fe Plug-In Hybrid Check Engine Light Reset

Resetting the check engine light on a 2023 Hyundai Santa Fe Plug-In Hybrid might be a simple software clear, but resetting before resolving the root cause can mask problems and lead to repeated codes or more extensive damage. At Larry H. Miller Hyundai Peoria we recommend a full diagnostic and proper repair before any reset. Our technicians use Hyundai OEM tools to read freeze frames, verify adaptive values, and confirm repairs so that a reset reflects a true fix rather than a temporary clear. Doing this at our dealership ensures OEM parts, certified labor, and warranty integrity—repairs covered under warranty must be performed at a certified dealership to remain valid. We also offer transparent pricing and often deliver better value than independent shops, plus service financing to help spread costs. For convenience, you can schedule service online, review current service specials, and rely on our factory-trained technicians to document work and provide a lasting solution that preserves performance and resale value.
