Check Engine Light Flashing

The check engine light flashing on a 2022 Lexus RX 350 is an urgent signal indicating potential misfires or conditions that could damage the catalytic converter. When a light flashes, immediate attention is important to prevent escalation: misfires can lead to unburnt fuel entering the exhaust and overheating or destroying emissions hardware, which becomes an expensive repair. At Herb Chambers Lexus of Hingham our technicians perform a systematic diagnosis using Lexus-approved tools to identify misfire sources — typically ignition coils, spark plugs, fuel delivery, or sensor failures. Choosing our dealership means factory-trained technicians, OEM replacement parts, and a transparent repair plan that emphasizes both immediate resolution and long-term reliability.
