Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Kia Seltos?

• Loose or faulty gas cap and evaporative system leaks (EVAP) are frequent, low-cost causes that often trigger the light.
• Oxygen sensor failures and catalytic converter efficiency codes are common and can reduce fuel economy if not addressed.
• Ignition misfires (spark plugs, coils) appear regularly and can escalate into engine or converter damage when ignored.
• Our dealership identifies the root cause with OEM diagnostics, then explains immediate and long-term savings from prompt, certified repairs.

What does it mean when the check engine light comes on in a 2026 Kia Seltos?

• An illuminated check engine light indicates the vehicle’s onboard computer detected an emissions, ignition, fuel, or sensor issue.
• Codes can point to minor issues (loose cap, sensor) or serious faults (misfire, catalytic damage) that need different interventions.
• We use full OEM scans to interpret codes, prioritize safety repairs, and provide transparent cost and timeline estimates.
• For any warranty-covered fault, repairs must be completed at a certified dealership to protect your coverage and ensure proper parts and updates.

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

• Start with a visible inspection: check that the fuel cap is tight and properly seated — a quick fix for many EVAP codes.
• Note any driving changes: rough idle, loss of power, or unusual sounds can indicate misfires or fuel issues that require immediate attention.
• Bring your 2026 Kia Seltos to our service center for a fast scan; our technicians verify codes and advise whether a simple reset or full repair is needed.
• When under warranty, have a certified dealership complete any covered repairs to maintain protection and ensure genuine parts.

How much does a check engine light diagnostic cost for a 2026 Kia Seltos?

• Typical diagnostic scans at our dealership are competitively priced; exact fees vary, but many scans fall in an affordable range with clear estimates up front.
• Because we identify root causes precisely, customers often save money immediately and over time by avoiding repeated visits or unnecessary parts replacements.
• If warranty coverage applies, remember repairs covered under warranty must be performed at a certified dealership to preserve benefits and ensure proper parts and software updates.
• We provide transparent quotes and explain how dealership service can cost less than independent shops while delivering factory-trained technicians and OEM equipment.

How long does a check engine light service take?

• Scan and initial diagnosis typically take 30–60 minutes depending on symptoms and code complexity.
• Simple fixes (tighten gas cap, replace a sensor) can be completed the same day; more complex repairs (misfire diagnosis, catalytic converter work) require additional time and parts.
• Our technicians prioritize accurate diagnosis to prevent repeat visits, saving customers time and money in the long run.
• If your vehicle is under warranty, having a certified dealership perform the work ensures coverage remains valid and any required software or parts updates are applied correctly.
