We use OEM-level scanners and hybrid-capable diagnostic tools to isolate the cause—whether an ignition component, sensor, fuel delivery issue, or hybrid-system event—and we present you with transparent options and cost-efficient repair plans. Addressing a flashing light promptly at our dealership not only prevents more expensive repairs later but also preserves warranty eligibility and resale value. We make scheduling simple: schedule appointment online, review current service specials, and ask about service financing to start repairs right away.
