Check Engine Light Flashing

The moment a check engine light starts flashing on a 2023 Lexus LC 500 Convertible, treat it as urgent.

At Herb Chambers Lexus of Sharon in Sharon, MA, our factory-trained technicians use OEM diagnostic tools to pinpoint whether the issue is ignition-related, fuel delivery, or sensor failure. Choosing our dealership means transparent diagnostics, genuine Lexus parts, and repairs performed to factory standards. We also offer service financing so you can get immediate repair work without delaying service. To protect performance and long-term ownership costs, visit our service center promptly; check current service specials and schedule service online for a fast appointment.
