Check Engine Light Flashing

The moment a check engine light starts flashing in your 2026 Hyundai Santa Fe, it signals a potentially serious condition that requires immediate attention. A flashing light often means misfires or conditions that can damage the catalytic converter or other emissions and drivetrain components. At Herb Chambers Hyundai of Auburn in Auburn, MA, our technicians prioritize safety and long-term vehicle health: we perform a comprehensive diagnostic scan, inspect ignition and fuel systems, check for misfires, and evaluate the battery and charging system as part of our root-cause approach. Acting quickly reduces repair scope and cost; leaving a flashing light unchecked can turn a simple ignition or charging repair into a catalytic converter replacement or engine damage that is far more expensive. We maintain transparency in estimates, use OEM parts, and back work with dealer warranties. Ask about our current service specials, and if you need service immediately, schedule service online to reserve a bay and get prioritized inspection.
