What is the first thing to check when the check engine light comes on?

Always check the gas cap first—an improperly sealed cap is a common, inexpensive cause and can trigger emissions codes.
If the cap is secure, schedule a diagnostic scan with our service center to read fault codes and assess severity.
Our factory-trained technicians use OEM tools to confirm root causes and recommend repairs that preserve warranty and long-term value.
Doing the work at a certified dealership can reduce overall costs over time through accurate diagnosis and manufacturer-backed parts and procedures.

How long does a check engine light service take?

Initial code reading typically takes 15–30 minutes; a full diagnostic inspection may require 1–2 hours depending on complexity.
Simple fixes (gas cap, sensor replacement) may be completed the same day; more involved repairs require parts and additional time.
Our advisors provide realistic time estimates and keep you informed; scheduling online at our service scheduler helps minimize wait time.
When repairs are covered under warranty, work must be performed at a certified dealership to ensure proper documentation and coverage.

What is the most common reason for check engine light on a 2017 Hyundai Azera?

Common causes include faulty oxygen sensors, loose or damaged gas caps, and ignition misfires from spark plugs or coils.
Fuel trim and air-fuel mixture issues (lean/rich codes) also frequently trigger the light on this engine configuration.
Timely dealer diagnostics catch the root cause early, often reducing parts and labor costs and preserving fuel economy.
Warranty-covered repairs must be completed at a certified dealership to ensure protection and maintain manufacturer standards.

2017 Hyundai Azera Check Engine Light Flashing

A flashing check engine light on your 2017 Hyundai Azera signals an active misfire or severe fault that can damage the catalytic converter and engine if driven. A flashing condition typically indicates unburned fuel entering the exhaust system, raising temperatures and risking costly downstream damage. Do not ignore a flashing lamp—limit driving, avoid heavy loads, and arrange immediate service. At Courtesy Hyundai of Tampa, our factory-trained technicians will perform a prompt diagnostic scan, inspect ignition, fuel delivery, and sensors, and recommend repairs. Because a flashing fault can escalate repair costs quickly, dealer diagnosis often minimizes long-term expense and ensures any warranty-related work is performed to manufacturer standards.

2017 Hyundai Azera Check Engine Light Reset

Resetting the check engine light on a 2017 Hyundai Azera can be done with an OBD-II scanner or by clearing codes after repairs, but erasing a code without fixing the root cause only masks problems. Our dealership uses OEM diagnostic tools to identify the underlying issue, correct it, and verify the repair so the light stays off reliably. Servicing at Courtesy Hyundai of Tampa often costs less than independent shops when factoring accurate diagnosis, genuine parts, and reduced return visits—delivering immediate savings and protecting long-term value. Remember, any repairs covered under warranty must be completed at a certified dealership to preserve coverage and properly document work.

2017 Hyundai Azera Check Engine Light Codes

Common codes for the 2017 Hyundai Azera include P0300 (random misfire), P0171/P0174 (system too lean), P0420 (catalyst efficiency), P0135 (O2 sensor heater), and P0442 (EVAP small leak). Left unaddressed, misfires can damage the catalytic converter ($1,000–$2,500+), lean conditions reduce fuel economy and stress components, and failed O2 sensors or EVAP leaks lead to repeated drivability issues and emissions failures. Repair costs vary: sensors and small parts often range from $100–$400, while major exhaust work is higher. Rely on our dealership for precise diagnosis, transparent estimates, and factory-trained service that helps reduce immediate costs and prevents expensive future repairs.
