Frequently Asked Questions

What is the most common reason for check engine light on a 2013 Hyundai Azera?

• Common causes include a loose or faulty gas cap, failing oxygen sensors (codes like P0420), ignition misfires (P0300-series), EVAP leaks (P0455) and aging spark plugs or coils.
• Minor items like a loose gas cap are inexpensive to fix; sensors and ignition parts are moderate, while catalytic converter failure is the most costly.
• Addressing issues early reduces repair costs and prevents secondary damage such as catalytic converter overheating.
• Our factory-trained technicians diagnose and repair with OEM parts, often delivering lower total cost of ownership than independent shops over time.

What does it mean when the check engine light comes on in a 2013 Hyundai Azera?

• A steady light signals a detected fault stored in the vehicle’s computer—anything from emissions issues to engine performance anomalies.
• A light can indicate an emissions control issue (EVAP), sensor failures (O2, MAF), misfires, or fuel system problems that affect drivability and economy.
• We recommend prompt diagnostic scanning; unresolved faults can lower fuel efficiency and risk further component damage.
• If your vehicle is under warranty, repairs must be performed at a certified dealership to preserve coverage—our service team handles warranty work and documentation.

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

• Start with simple checks: ensure the gas cap is tightened and inspect for obvious fuel smells or drivability changes.
• If the cap is secure but the light remains, get a diagnostic scan to retrieve trouble codes—this reveals the system or component at fault.
• Don’t rely on resetting the light without repair; codes will return and underlying damage can worsen.
• Use our service scheduler to book a quick inspection with Hyundai-trained technicians who can advise on warranty eligibility and repair options.
