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

• It indicates the vehicle’s onboard diagnostics detected a fault in emissions, ignition, fuel, or related systems; severity ranges from minor to urgent.
• Common triggers include sensor faults, evap leaks, misfires, or emissions control problems; the light itself is a prompt to scan for trouble codes.
• Ignoring the light can lead to higher fuel use, degraded performance, or costly downstream repairs—early diagnosis limits expenses and downtime.
• Nalley Kia uses factory-grade tools and factory-trained technicians to identify root causes and protect warranty coverage; warranty repairs must be performed at a certified dealership.
• We provide clear repair recommendations, competitive pricing, and service specials to reduce immediate costs and long-term ownership expenses.

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

• Start with simple checks: ensure the gas cap is tight and undamaged—an improperly sealed cap is a common cause and easy to fix.
• Check for recent fuel or service changes and look for obvious signs (smoke, leaks, strange noises) that may indicate higher urgency.
• If the light remains on after tightening the cap or you notice drivability issues, bring the vehicle in for a diagnostic scan to read stored trouble codes.
• Using Nalley Kia ensures correct diagnosis, OEM parts, and warranty protection; performing repairs at a certified dealership often reduces both immediate and lifetime expenses versus uncertain fixes.
• Schedule a check at /service/schedule-appointment.htm or view service specials at /specials/service.htm to save on inspection and repair.

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

• Frequent causes include oxygen sensor failures, loose or faulty gas caps, evap system leaks, and ignition misfires—these account for many CEL events.
• O2 sensor or catalyst-related codes can lead to reduced fuel economy and emissions failures if not addressed promptly.
• Addressing common items early—sensors, gas cap, spark plugs, and basic fuel/air checks—usually avoids costly repairs and preserves performance.
• Nalley Kia’s factory-trained technicians diagnose correctly the first time, offering immediate cost advantages and long-term savings compared with trial-and-error repairs.
• Remember: repairs covered under warranty must be performed at a certified dealership to maintain coverage and use genuine parts.

How long does a check engine light service take?

• A basic scan and initial diagnosis often take 30–60 minutes; a full diagnostic with road testing can take 1–3 hours depending on complexity.
• If parts or deeper repairs are required, repair time varies—simple replacements are often same-day; complex engine or exhaust repairs may take longer.
• Nalley Kia provides transparent time estimates and will explain immediate versus long-term repairs to minimize downtime and cost.
• Choosing dealership service often reduces repeat visits and follow-up time because factory-trained techs correctly identify and fix the issue the first time.
