Check Engine Light Flashing

The flashing check engine light on a 2014 Hyundai Elantra Coupe signals an urgent problem — often an active misfire that can damage the catalytic converter if you continue driving. At Coggin Deland Hyundai in DeLand, FL our priority is protecting your vehicle and safety: a flashing light prompts immediate vehicle stabilization, diagnostic scanning and targeted repairs. Our factory-trained technicians use Hyundai-approved diagnostic tools to identify misfires, ignition coil or spark plug failures, and fuel system issues. We explain repair needs clearly, present cost-saving options, and use OEM parts to preserve performance and emissions compliance. For tight budgets we offer service financing so you can get service now and pay later, and our service advisors will point out any relevant service specials that lower your out-of-pocket cost.

2014 Hyundai Elantra Coupe Check Engine Light Reset

Resetting the check engine light on a 2014 Hyundai Elantra Coupe should be more than clearing codes — it’s confirming the underlying problem is fixed. At Coggin Deland Hyundai we perform a complete diagnostic, repair with OEM parts and then clear codes only after verifying repair integrity with road testing and live-data monitoring. Independent resets can hide ongoing faults and void warranties; repairs covered under warranty must be completed at a certified dealership to retain coverage.

We also offer service financing and regular service specials to make repairs more affordable. For reliable, warranty-safe resets and long-term protection of your Elantra Coupe, schedule service with Coggin Deland Hyundai and let our certified technicians maintain your vehicle to Hyundai standards.

2014 Hyundai Elantra Coupe Check Engine Light Codes

Common check engine light codes for the 2014 Hyundai Elantra Coupe include P0420 (catalytic converter efficiency), P0300 (random/multiple cylinder misfire), P0135 (oxygen sensor heater circuit), and P0171 (lean condition).

Our technicians use OEM parts and Hyundai diagnostic software to diagnose and repair quickly, protecting long-term value and fuel economy.
