Check Engine Light Flashing

The check engine light flashing on a 2011 Hyundai Elantra is a critical signal — it often indicates a misfire that can damage the catalytic converter, impair drivability, and create a safety concern. When you see a flashing light, stop driving if the vehicle is running roughly or if you notice loss of power; continuing to drive can multiply repair costs. At Coggin Deland Hyundai in Deland, FL, our certified technicians prioritize immediate diagnostics and repair. We use factory-level tools to isolate ignition, fuel, and sensor failures, then present clear options: a fast repair using OEM parts, warranty coverage verification (repairs under warranty must be done at a certified dealership), or a staged plan to protect long-term value. We also promote savings through efficiency — quick, correct repairs at our service center prevent repeat failures and reduce total ownership cost. Take advantage of our current service specials or schedule appointment online to get priority attention and restore safe operation.
