Check Engine Light Flashing

A flashing check engine light on a 2025 Ford F-350 Super Duty King Ranch indicates a severe condition — often a misfire or issue causing unburned fuel to enter the exhaust. This can damage the catalytic converter and lead to expensive repairs if ignored. For heavy-duty trucks like the F-350, a flashing light during towing or under heavy load is especially urgent because sustained misfires can overheat engine components. At Larry H. Miller Super Ford Salt Lake City, our technicians will prioritize a rapid diagnosis, using OEM diagnostic tools to identify whether the cause is ignition-related, fuel delivery, or another engine system fault. We emphasize transparent communication: you'll receive a clear estimate and repair plan, plus available discounts listed on our service specials page. Repairs under warranty must be completed at a certified dealership to preserve coverage. If you see a flashing light, do not delay — schedule service immediately to protect your truck and minimize long-term costs.
