Check Engine Light Flashing

The check engine light flashing in a 2013 Hyundai Elantra GT signals a potentially severe misfire or condition that can damage the catalytic converter and other components if driven for long. A flashing light often means the engine is misfiring enough to allow unburned fuel into the exhaust, raising emissions and generating heat that harms downstream systems. At Stevinson Hyundai in Colorado, our certified technicians perform rapid priority diagnostics to identify ignition faults, fuel delivery issues, or sensor failures that cause a flashing condition. We explain immediate risks, present cost-effective repair options, and prioritize repairs that prevent larger future expenses—demonstrating both immediate and long-term savings. All work uses OEM parts and follows manufacturer procedures; warranty-covered repairs must be done at a certified dealership, and we handle warranty claims for you. Check our current service specials for potential savings, and schedule service online to get same-day attention and protect your vehicle today.
