Frequently Asked Questions

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

• Check for loose or damaged gas cap—an easy fix that can clear the light and restore EVAP system function.
• Verify fuel level and recent fueling activity; contaminated or low fuel sometimes triggers codes.
• Look for obvious under-hood issues (disconnected hoses, frayed wiring, visible leaks) but avoid attempting complex repairs yourself.
• If the light persists, bring your 2012 Hyundai Genesis Coupe 2.0T to our service team for a professional scan; warranty-covered repairs must be done at a certified dealership.

How long does a check engine light service take?

• Typical diagnostic scan and initial inspection usually take 30–90 minutes, depending on symptom complexity.
• Minor repairs (sensor replacement, gas cap, small vacuum hose) can often be completed the same day.
• More involved repairs (ignition, catalytic converter, fuel system) may take several hours or require parts and a return visit.
• At Courtesy Hyundai of Tampa we prioritize fast turnaround with factory-trained technicians, often delivering immediate and long-term savings versus independent shops.
