Check Engine Light Flashing

A flashing check engine light on your 2014 Hyundai Elantra GT is an urgent indicator—often signaling active misfires that can damage the catalytic converter and compromise safety. When the light flashes, immediate attention from certified technicians is essential. At Arapahoe Hyundai in CO, our team prioritizes flashing-light cases and performs a comprehensive inspection that includes a code read, ignition system check, fuel system diagnostics, and emissions components assessment. Beyond identifying the immediate fault, we explain the impact of delaying repairs: reduced fuel economy, higher emissions, potential catalytic converter failure, and greater repair bills later. Our process is transparent—every recommended repair comes with an itemized estimate, OEM parts, and an explanation of how dealer-certified work delivers long-term savings through proper installation and warranty protection. We also provide service financing options so you can address urgent repairs now and pay over time.

2014 Hyundai Elantra GT Check Engine Light Codes

Common check engine light codes on a 2014 Hyundai Elantra GT include P0420 (catalyst system efficiency), P0300–P0304 (random/multi-cylinder misfires), P0171/P0174 (fuel trim lean), and oxygen sensor codes. Each code points to different root causes and potential costs if left unrepaired. For example, ignoring a P0420 can lead to complete catalytic converter failure (a costly replacement), while unaddressed misfires (P0300 series) can damage pistons and converters. At Arapahoe Hyundai, our diagnostic approach quantifies the issue and outlines cost-effective solutions—often costing less overall than independent shops because dealer repairs prevent recurring problems and preserve factory warranties. We use OEM parts, which maintain vehicle performance and resale value. Our shop in CO is equipped with Hyundai-specific tools and factory-updated repair procedures, enabling efficient fixes and clear communication.
