Check Engine Light Flashing

The moment a check engine light flashes in your 2019 Lexus IS 350 it signals a potential active misfire or a condition that could cause immediate engine or emissions system damage if you continue driving. A flashing light usually indicates a more urgent fault than a steady light; symptoms may include stalling, reduced power, rough running, or increased exhaust odor. At Park Place Lexus Grapevine in Grapevine, TX, our certified Lexus technicians prioritize flashing conditions and perform a focused diagnostic using factory-grade tools to isolate misfires, catalytic converter risk, or severe ignition problems. Immediate service prevents larger repairs, preserves fuel economy, and maintains emissions compliance. We document findings, discuss OEM vs. aftermarket part choices, and explain warranty implications — any warranty repairs must be completed at a certified dealership to remain valid.
