Check Engine Light Flashing

The check engine light flashing on a 2020 FIAT 500L signals an active misfire or severe issue that can damage the catalytic converter and other components if you continue driving. A flashing indicator often means fuel is not burning correctly in one or more cylinders, creating unburned fuel that reaches the exhaust and overheats emission components. At Larry H. Miller Dodge RAM FIAT Tucson in Tucson, AZ, our factory-trained technicians prioritize flashing codes because they can escalate quickly into costly repairs. We use OEM-grade diagnostic tools to determine whether the cause is ignition coils, spark plugs, fuel injectors, or turbocharger-related issues and provide a clear repair plan with cost estimates and timeline. We promote immediate and long-term savings by addressing the root cause, avoiding cascade failures, and using genuine parts backed by warranty. Ask about our current service specials, and when you're ready to get immediate attention, schedule service online to reserve a prompt appointment. Our goal is safe, efficient repairs and a quick return to the road with confidence.
