Check Engine Light Flashing

A flashing check engine light in your 2015 Hyundai Elantra GT is a signal that a severe condition—often a misfire—is occurring. A flashing light can indicate that unburned fuel is entering the exhaust system, risking catalytic converter damage and increased emissions. Immediate attention reduces repair scope and long-term expense; postponing service can multiply parts and labor costs while compromising fuel efficiency and engine life. At Arapahoe Hyundai in CO, our certified technicians use Hyundai factory diagnostic tools to pinpoint the cause quickly, minimizing downtime.

2015 Hyundai Elantra GT Check Engine Light Codes

Common codes for a 2015 Hyundai Elantra GT include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0171/P0174 (fuel trim lean), and P0135 (oxygen sensor heater). Each code carries different costs and consequences: ignoring a P0420 can damage the catalytic converter (a higher-cost replacement), while unaddressed misfires (P0300) can damage pistons or catalytic components. At Arapahoe Hyundai in CO, we diagnose the exact failure and present repair options that focus on long-term value—correct parts, precise labor, and warranty-backed service. Our certified Hyundai technicians explain immediate repair needs and how timely service reduces total ownership costs.
