What does it mean when the check engine light comes on in a 2026 Hyundai Santa Fe?

• It signals the vehicle’s onboard diagnostics detected an emissions or engine-related fault—common causes include oxygen sensor, catalytic converter, misfire, or EVAP leaks.
• A steady light often indicates a non-emergency emissions or sensor issue; a flashing light usually signals an active misfire that can damage the catalytic converter and needs immediate attention.
• At Nalley Hyundai we perform a full OBD-II scan, pinpoint root cause, and explain repair options so you avoid unnecessary expense and protect resale value.
• Warranty-covered diagnostics and repairs must be completed at a certified dealership to preserve coverage and ensure OEM parts are used.

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

• Start with simple checks: ensure the fuel cap is tightened (a loose cap is a frequent cause) and verify oil and coolant levels to rule out basic issues.
• Listen for rough idling or loss of power—these symptoms help prioritize service urgency; flashing or severe performance loss means stop driving and seek immediate service.
• Even after simple fixes, get a professional scan at Nalley Hyundai so underlying codes aren’t missed; dealership diagnostics prevent repeat failures and save money long term.
• Remember: if your vehicle is under warranty, repairs must be done at a certified dealership to maintain coverage and ensure correct procedures and parts.

How long does a check engine light service take?

• Basic OBD-II diagnostics typically take 30–90 minutes; many common repairs (sensor replacement, tightening caps, minor hose repairs) can be completed same day.
• More extensive issues—catalytic converter replacement or engine repairs—can require one to several days depending on part availability and repair complexity.
• Nalley Hyundai’s factory-trained technicians and OEM parts streamline service, often delivering faster turnaround and lower long-term costs than repeated visits to independent shops.
• If the repair is warranty-covered, having work done at a certified dealership ensures timely authorization and preserves your warranty benefits.
