Check Engine Light Flashing

The check engine light flashing on a 2014 Hyundai Elantra GT usually indicates an active misfire or a condition that can damage the catalytic converter if driven. A flashing indicator is a higher-priority alert than a steady light — it means combustion is not occurring correctly in one or more cylinders, which can lead to overheating, increased emissions, loss of power, or severe converter damage. At Larry H. Miller Hyundai Peoria in Peoria, AZ, our factory-trained technicians diagnose flashing-light conditions immediately using OEM-level scanners and proven procedures. We explain each fault code, outline repair options, and show the estimated costs and time to repair so you can make an informed decision. Our service lane emphasizes speed and accuracy: many inspections are completed the same day, and we offer service specials and service financing so urgent repairs don’t wait. If your 2014 Hyundai Elantra GT light is flashing, do not delay — schedule service to protect performance and avoid higher downstream costs.
