Check Engine Light Flashing

The check engine light flashing on a 2024 Hyundai Elantra is a critical warning that indicates an active misfire or condition that can damage the catalytic converter if driven. A flashing light often means unburned fuel is entering the exhaust, creating heat that can irreparably harm emission-control components. At Arapahoe Hyundai in Colorado, we treat flashing CELs as urgent: our Hyundai-certified technicians perform a fast, thorough inspection using OEM diagnostic equipment, isolating misfires, ignition coils, fuel injectors, and related systems. Choosing dealership service provides immediate advantages — precise diagnostics, genuine Hyundai parts, and repairs that protect your vehicle’s warranty and long-term value. We also offer transparent estimates and service financing so you can address urgent repairs without delay. Before you drive extensively, please schedule service online; check our service specials to reduce costs, and rely on Arapahoe Hyundai’s customer-first process to get you back on the road safely.
