Check Engine Light Flashing

A flashing check engine light on a 2016 Hyundai Genesis Coupe is an urgent warning that the engine is misfiring or a condition exists that could cause catalytic converter damage or loss of power. In many cases a flashing light reflects active misfires caused by failing ignition coils, worn spark plugs, or fuel injection issues; continued driving can overheat and destroy the catalytic converter—a costly repair that is avoidable with prompt service. At Stevinson Hyundai in CO our factory-trained technicians prioritize immediate diagnostics to identify whether towing, limited driving, or stopped operation is required.

2016 Hyundai Genesis Coupe Check Engine Light Reset

Resetting the check engine light on a 2016 Hyundai Genesis Coupe without resolving the underlying code may provide temporary relief but risks masking progressive damage and voiding certain protections. At Stevinson Hyundai, we explain why a reset is only the final step after confirmed repair: resetting before repair can erase important freeze-frame data needed to diagnose intermittent faults and can lead to repeat trips and higher lifetime costs. Our process begins with a full code read using OEM-level equipment, followed by a clear estimate and parts recommendation, and we always discuss the warranty implications—repairs covered under warranty must be completed at a certified dealership to remain valid. Choosing our service delivers immediate savings through correct diagnosis, and long-term savings through OEM parts and technician expertise. We also post available service specials and offer service financing so you can schedule service now and pay over time. Trust and transparency are core—our team documents findings, offers options, and preserves your vehicle’s performance and value.

2016 Hyundai Genesis Coupe Check Engine Light Codes

Common diagnostic trouble codes for the 2016 Hyundai Genesis Coupe include P0300 (random/multiple cylinder misfire), P0301–P0306 (cylinder-specific misfires), P0420 (catalyst system efficiency), P0171/P0174 (fuel trim lean), and oxygen sensor codes. Each code implies a different urgency and cost if unaddressed: misfires can lead to catalytic converter failure and decreased fuel economy; unresolved O2 sensor faults increase emissions and fuel use; EVAP leaks raise check-engine triggers and risk failed inspections. At Stevinson Hyundai in CO our certified technicians will explain the likely root causes and estimate repair costs, emphasizing how early diagnosis avoids cascade failures and larger bills later. We provide OEM parts, documented repair history, and warranty-backed work that keeps your Genesis Coupe running stronger longer.
