Check Engine Light Flashing

The check engine light flashing on a 2025 Hyundai Santa Fe signals an active misfire or another condition that may cause catalytic converter damage if driven. A flashing indicator is more urgent than a steady light: it means the engine is running outside of safe parameters and immediate attention is needed. At Stevinson Hyundai in CO our technicians use Hyundai-specific diagnostic tools to read OBD-II trouble codes, assess turbocharger and ignition systems, and determine whether the issue is an ignition coil, spark plug, fuel injector, or related sensor. Addressing a flashing light promptly can prevent costly downstream damage and preserve fuel efficiency, emissions performance, and long-term reliability. We make this convenient—book a time online to schedule service, review available incentives via our service specials, and ask about service financing to manage repair costs. Our team emphasizes speed, transparency, and OEM-quality repair so you return to the road with confidence.

2025 Hyundai Santa Fe Check Engine Light Codes

Common codes on a 2025 Hyundai Santa Fe include P0420 (catalyst system efficiency), P0300–P0304 (random or cylinder misfires), P0171/P0174 (fuel trim lean), and various turbocharger or boost pressure sensor codes. Each code carries different risk and cost implications: ignoring a P0420 can lead to catalytic converter failure and a high repair bill; untreated misfires can damage the catalytic converter and reduce engine life; persistent lean conditions increase fuel use and stress turbo systems. At Stevinson Hyundai in CO we provide clear estimates and explain immediate and long-term savings—repairing faults early often costs less overall than delaying service. Our certified Hyundai technicians use OEM parts and factory procedures so repairs restore original performance and maintain warranties. We also offer practical conveniences like online booking to schedule appointment, competitive pricing, and regular service specials to reduce your out-of-pocket expense while delivering factory-standard care.
