What does it mean when the check engine light comes on in a 2025 Kia K5?

• The light indicates the vehicle’s onboard diagnostics detected an emissions, engine, or sensor issue—ranging from a loose gas cap to a misfire or oxygen sensor problem.
• Common causes include loose or faulty gas cap, oxygen sensor degradation, catalytic converter issues, ignition misfires, or evaporative system faults.
• Some issues are minor; others can cause fuel economy loss, higher emissions, or engine damage if ignored—prompt diagnosis prevents escalation.
• For warranty protection and the most reliable repair outcome, have any warranty-covered work completed at our certified dealership.

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

• Start simple: ensure the gas cap is tightened properly—many CEL triggers come from a loose or damaged cap and are easily fixed.
• Note vehicle behavior: reduced power, rough idle, or unusual noises help prioritize urgency; a flashing light signals a severe condition—stop driving.
• If the vehicle runs normally, schedule a diagnostic; if performance is affected or the light flashes, contact us immediately or arrange a tow to prevent further damage.
• Remember: repairs covered by warranty must be done at a certified dealership to preserve coverage and ensure proper parts and procedures.

How long does a check engine light service take?

• Initial diagnostics often take 30–90 minutes depending on symptoms and the tests required to identify codes and root causes.
• Simple fixes—like tightening a gas cap or replacing a sensor—can be completed same day; complex repairs may require parts ordering and additional time.
• Courtesy Kia of Brandon streamlines the process with factory training, OEM parts inventory access, and service specials to reduce wait times and overall cost.
• We emphasize timely, correct repairs that save you money over time; warranty work must be performed at a certified dealership to remain valid.

What is the most common reason for check engine light on a 2025 Kia K5?
