Check Engine Light Flashing

A flashing check engine light on your 2024 Hyundai Tucson Plug-In Hybrid signals a potentially severe condition that requires immediate attention.

At Coggin Deland Hyundai in Deland, FL, our factory-trained technicians prioritize safety and rapid diagnosis. We use Hyundai OEM tools and hybrid-capable diagnostic equipment to isolate whether the behavior is caused by ignition, fuel delivery, sensor failures, or battery-system anomalies. Acting quickly protects critical components and avoids costly downstream repairs; a fast fix can preserve battery health and fuel/electric efficiency. We recommend you stop driving if the vehicle is unstable and schedule service immediately. Check our service specials for current offers — and remember, warranty-related work must be completed at a certified dealership.

2024 Hyundai Tucson Plug-In Hybrid Check Engine Light Reset

Resetting a check engine light on a 2024 Hyundai Tucson Plug-In Hybrid is more than clearing a code; it’s about ensuring the root cause is found and fixed.

We explain costs up-front, and because accurate repairs reduce repeat visits, our approach often costs less over time than piecemeal fixes at independent shops. For convenience, schedule service online and review current service specials. If your vehicle is under warranty, repairs must be done at a certified dealership to remain covered. We also offer service financing so you can get the work completed promptly and preserve the value and performance of your Tucson Plug-In Hybrid.
