Frequently Asked Questions

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

• Faulty oxygen sensors or catalytic efficiency issues (codes like P0420) are common and affect fuel economy and emissions.
• Ignition misfires (P0300-series) from coils, plugs or fuel delivery degrade power and can damage the catalytic converter.
• EVAP leaks (P0455/P0442) from a loose gas cap or hose will trigger the light and cause failed emissions tests.
• Addressing problems early at our dealership often costs less than independent shops, since factory-trained techs find root causes faster and protect long-term value.

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

• The light signals the engine control module detected an emissions or performance fault — from minor to severe.
• It can indicate sensor faults, misfires, fuel trim issues, EVAP leaks, or catalytic converter problems.
• At Courtesy Hyundai of Tampa we perform a full diagnostic scan to read codes, test components, and recommend OEM repairs to preserve warranty coverage.
• Remember: any repairs covered under warranty must be performed at a certified dealership to maintain coverage and long-term savings.

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

• Check the gas cap for a secure fit; a loose or damaged cap can trigger EVAP system codes.
• Verify oil level and look for obvious leaks; low oil can correlate with performance issues and warnings.
• Note driving symptoms (loss of power, rough idle, stalling) and share them with our service team for faster diagnosis.
• Bring your 2013 Hyundai Genesis Coupe to our service center for a certified diagnostic — early dealership intervention saves immediate and long-term repair costs.

How much does a check engine light diagnostic cost for a 2013 Hyundai Genesis Coupe?

• Diagnostic prices vary by scope; typical OBD-II scans and initial diagnostics often range from a complimentary code read during specials to modest diagnostic fees for in-depth testing.
• At Courtesy Hyundai of Tampa we provide transparent estimates and often deliver lower total cost than independent shops because OEM parts and correct repairs avoid repeat visits.
• Immediate savings come from accurate diagnosis and proper repairs; long-term savings come from preserved emissions systems, fuel economy, and avoided major repairs.
• If a repair is covered under warranty it must be completed at a certified dealership to retain coverage — we handle those claims directly for your benefit.

How long does a check engine light service take?

• Simple code reads and minor repairs (tighten gas cap, replace a sensor) can take less than an hour with our express service options.
• Complex diagnostics or repairs (diagnosing intermittent misfires, replacing catalytic converter) take longer; we provide accurate time estimates after the initial scan.
• Dealership service often speeds resolution because we use OEM tools, access factory repair procedures, and stock common parts, reducing repeat visits and downtime.
• Schedule online at our service scheduler for a clear arrival time and ask about current service specials to maximize immediate savings.
