Check Engine Light Flashing

The flashing check engine light on a 2010 Lexus LS 460 L signals a serious misfire or condition that can damage the catalytic converter and other components if driven long.

Choosing our dealership provides transparent estimates, genuine OEM parts, and the benefit of warranty protection for covered repairs. We regularly offer service specials and convenient financing so repairs can be completed without delay.
