A flashing check engine light on a 2026 Lexus ES is a higher-priority warning that typically indicates an active misfire or an issue causing unburned fuel to enter the exhaust system. Continued driving with a flashing light risks catalytic converter damage, reduced fuel economy, and potential loss of power. At Park Place Lexus in Plano, TX, our certified technicians react quickly: we run a full diagnostic scan, inspect ignition and fuel systems, and advise the safest next steps. Because we use OEM parts and factory procedures, repairs are precise and built to last—minimizing repeat visits and lowering lifecycle costs.

Common diagnostic trouble codes on a 2026 Lexus ES include P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency below threshold), and P0171/P0174 (fuel trim/system lean).
