Check Engine Light Flashing

A flashing check engine light on a 2014 Hyundai Elantra Coupe is a more urgent warning than a steady light. It typically indicates a misfire or condition that could cause catalytic converter damage, excessive emissions, or immediate drivability issues. When you see a flashing light, stop driving if the vehicle is unsafe and have it inspected as soon as possible. At Larry H. Miller Hyundai Peoria our factory-trained technicians prioritize flashing-light cases to limit further damage. We use OEM diagnostics to find root causes — from ignition coils and spark plugs to fuel system faults — and provide transparent repair plans. Choosing the dealership often costs less than independent shops over time because correct repairs prevent repeat visits and protect components covered by factory warranties. We also offer service financing and regular service specials to help manage costs. Schedule an appointment online to protect your vehicle and safety: schedule service.

2014 Hyundai Elantra Coupe Check Engine Light Reset

Resetting the check engine light on a 2014 Hyundai Elantra Coupe is a simple step but not a substitute for diagnosis.

Miller Hyundai Peoria always read and record codes before any reset, then recommend precise repairs using OEM parts to maintain performance and warranty coverage. We emphasize transparency: you’ll receive a clear explanation of findings, cost estimates, and options that reflect immediate and long-term savings. Using a certified dealership avoids unnecessary parts changes and repeated labor. We also support flexible payment with service financing and often run service specials to reduce cost.
