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

• The light signals the engine control module has detected a fault — anything from a loose gas cap to an emissions sensor, ignition misfire, or catalytic converter issue.
• Some faults are emissions-related and affect fuel economy or performance, while others can indicate an immediate risk to engine health.
• Our technicians read stored fault codes with OEM-level scanners to pinpoint root causes rather than guessing, reducing unnecessary repairs and saving you money.

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

• Start with the basics: check the gas cap is tight and undamaged, as a loose cap is a common trigger for the light on a 2013 Hyundai Elantra GT.
• If the cap is secure, let our service team scan the vehicle; OEM scanners identify the exact code quickly and accurately.
• Addressing simple issues early at our dealership often costs less than independent shops and prevents larger, costlier repairs later.
• Use our Service Specials to maximize savings when you bring your vehicle in.

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

• The most frequent causes include a loose or faulty gas cap, oxygen sensor failure, catalytic converter issues, or misfires related to ignition components.
• On the 1.8L engine, oxygen sensor and catalytic converter codes are common when emissions systems degrade over time.
• Repairing early at our dealership reduces long-term costs; we use OEM parts and diagnostics to avoid repeat visits that can happen after incomplete repairs at non-certified shops.
• Warranty-covered fixes must be completed at a certified dealership to maintain coverage, so bring your Elantra GT to Courtesy Hyundai of Tampa for authorized service.

How long does a check engine light service take?

• Basic code retrieval and inspection typically take 30–60 minutes; more involved repairs vary by diagnosis and parts availability.
• If the issue is simple — for example, gas cap, sensor swap, or minor ignition service — many vehicles are back the same day.
• Complex repairs such as catalytic converter replacement or in-depth engine repairs can take longer; we provide a clear time estimate after the initial scan to minimize surprises.
