Check Engine Light Flashing

The sight of a flashing check engine light on a 2022 Lexus NX 450h+ signals an active misfire or a condition that could damage the catalytic converter or hybrid systems if driven. A flashing light is a higher-priority alert than a steady light; it means immediate attention is recommended. At Park Place Lexus in Plano, TX, our factory-trained technicians begin with a full OEM diagnostic scan to isolate misfire codes, fuel delivery issues, ignition or battery system faults specific to the NX 450h+. Addressing a flashing light quickly preserves the catalytic converter and hybrid components and prevents costly downstream repairs. We document findings, explain necessary repairs in plain language, and offer OEM parts and manufacturer-grade replacement components to ensure safe, lasting results. Take advantage of our current service specials and available service financing so you can get the urgent attention your vehicle needs without delay.

2022 Lexus NX 450h+ Check Engine Light Reset

Resetting the check engine light on a 2022 Lexus NX 450h+ can be simple or misleading.

Our technicians use OEM diagnostic tools and follow manufacturer procedures so resets are accurate, any Software updates are applied, and zero-impact warranty coverage remains intact.
