2019 Hyundai Sonata Hybrid Check Engine Light Reset

The process to reset a check engine light on a 2019 Hyundai Sonata Hybrid can be simple or complex depending on root cause. A true reset requires clearing the stored diagnostic trouble codes only after the underlying issue is resolved. At Herb Chambers Hyundai of Auburn, we never recommend just clearing codes as a quick fix; our technicians first run a thorough OEM-grade scan to identify the specific fault, from emissions-related codes to hybrid battery management system alerts. Performing a reset without repair can mask a recurring problem and lead to greater repair costs and safety risks. Our service bays in Auburn, MA are equipped with factory software and genuine Hyundai parts, ensuring that any reset is permanent because the cause has been corrected. We back repairs with warranty support and offer service financing so customers can get safe, reliable workmanship now and pay over time. To protect your vehicle’s performance and value, please schedule service and review available service specials before you visit.
