Check Engine Light Flashing

A flashing check engine light on a 2022 Lexus IS 500 usually signals a serious misfire or an immediate engine management concern that can damage the catalytic converter or other components if driven.

Because a flashing light can indicate active misfires, we advise stopping driving when safe and arranging transport or tow to our service center to avoid more costly downstream damage. Our facility stocks OEM parts or orders them quickly, and we communicate a clear estimate before work begins. We also highlight available promotions—check our service specials—and offer service financing so you can address urgent repairs immediately without delay.
