Check Engine Light Flashing

A flashing check engine light on a 2023 Kia Sorento indicates an active misfire or condition that could damage the catalytic converter and reduce drivability. A flashing light is more urgent than a steady light — continuing to drive can worsen engine components and raise repair costs. At Nalley Kia in GA our technicians prioritize flashing-light diagnostics: we perform a thorough inspection of ignition, fuel, and exhaust systems, test cylinders for misfires, check fuel trims, and evaluate sensor data to isolate the fault. We explain findings in plain language, give itemized estimates, and use OEM parts to restore performance and protect emissions equipment. Take advantage of our service specials and service financing options to get repairs done now and pay over time. To avoid further damage and unexpected bills, schedule service with Nalley Kia today or contact our service team for immediate guidance.

2023 Kia Sorento Check Engine Light Reset

Resetting the check engine light on a 2023 Kia Sorento can be done, but clearing codes without fixing the underlying cause hides symptoms and risks recurring failures. Nalley Kia’s approach is to diagnose, repair, and then verify the fix before clearing codes — ensuring long-term reliability and preserving warranty coverage. We use factory scan tools and follow OEM reset procedures to maintain accurate vehicle health records. Choosing Nalley Kia over an independent shop means factory-trained technicians, genuine Kia parts, and documented service that protects resale value. We also provide clear cost breakdowns, and our service financing lets you authorize necessary repairs now while spreading payments.
