Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Kia Seltos?

• Loose or damaged gas cap leading to an EVAP leak — the simplest and most frequent cause.
• Faulty oxygen (O2) sensors or evaporative emission system components that affect emissions and fuel economy.
• Minor fuel trim or vacuum issues; if unchecked, these can escalate into costly repairs like catalytic converter damage.
• At Nalley Kia we diagnose the root cause with OEM-grade equipment; repairs done here provide immediate savings and protect long-term value.

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

• It signals that the vehicle’s onboard diagnostics detected a fault in emissions, engine, or powertrain systems.
• Codes can range from minor (EVAP leaks) to serious (misfires, catalytic converter issues) — each code points to a specific system.
• Ignoring the light can decrease fuel economy, increase emissions, and cause bigger repairs over time.
• Bring your Seltos to Nalley Kia for a precise scan and OEM fixes; warranty-covered items must be serviced at a certified dealership to remain valid.

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

• Check that the fuel cap is tightened properly; a loose cap often triggers an EVAP code.
• Look for obvious dashboard warnings (e.g., temperature or oil pressure) that indicate immediate risk.
• If symptoms like rough idle or loss of power appear, limit driving and schedule service to prevent further damage.
• Schedule an appointment with Nalley Kia so factory-trained technicians can run a full diagnostic and preserve any warranty coverage.
