Frequently Asked Questions

What does it mean when the check engine light comes on in a 2025 Kia Sportage?

• It signals that the vehicle’s engine control unit has detected a fault — anything from a minor emissions issue to a serious drivability problem.
• A steady light usually indicates a non-urgent fault; a flashing light can indicate a severe misfire that risks catalytic converter damage.
• We recommend scheduling a diagnostic at Courtesy Kia of Brandon so factory-trained technicians can read manufacturer codes and recommend the correct repair.
• Prompt dealer diagnosis saves money over time by preventing escalation and protecting warranty coverage when work is done at a certified location.

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

• Start simple: ensure the gas cap is tight and undamaged — a loose cap is a common, quick fix that often clears the light.
• Note any symptoms: rough idle, loss of power, unusual smells, or fluid leaks — these details speed diagnosis.
• Check the dashboard for other warnings and avoid hard driving if performance is affected; bring the vehicle to our service center for a scan.
• If covered by warranty, repairs must be completed at a certified dealership like Courtesy Kia of Brandon to maintain coverage and ensure proper procedures.
