Check Engine Light Flashing
A flashing check engine light on a 2023 Lexus RX 350h is an urgent warning that should not be ignored.

Immediate attention at a certified dealership prevents damage to catalytic converters, hybrid drive components, or battery modules. At Park Place Lexus in Plano, TX, our technicians use Lexus OEM diagnostic tools to isolate whether the flashing is caused by ignition problems, fuel system anomalies, or hybrid battery management alerts. We prioritize diagnostic speed and transparency, providing clear estimates and explaining the immediate and long-term savings of repairing issues now rather than later. We also offer service financing so you can address urgent repairs without delay, and our service advisors will point out any eligible service specials.
