What does it mean when the check engine light comes on in a 2023 Kia Rio?

• It signals the vehicle’s onboard computer detected an issue in emissions, ignition, fuel delivery, or sensors — not always an emergency but always worth checking.
• Common causes include a loose gas cap, oxygen sensor wear, EVAP leaks, ignition misfires, or catalytic converter performance problems.
• Ignoring the light can increase fuel use, cause emissions failure, and lead to more expensive repairs over time.
• Our factory-trained technicians perform a full diagnostic scan and explain immediate and long-term cost implications and warranty options.

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 intact—this common issue frequently triggers the light.
• Check visible fluids and look for obvious problems (smoke, loss of power, unusual noises) that could indicate a serious fault.
• If no clear issue is found, bring the vehicle for a diagnostic scan; our technicians will read codes and recommend repairs.
• Any repair covered under warranty should be completed at a certified dealership to maintain coverage and ensure genuine parts.
• Use our Service Specials and online scheduling to get prioritized, cost-effective service from Courtesy Kia of Brandon.

How long does a check engine light service take?

• Initial diagnosis with a scan typically takes 20–60 minutes depending on code complexity and required tests.
• Simple repairs (gas cap, sensor replacement) may be completed the same day; more involved repairs (catalytic or engine work) can take longer.
• We provide a clear time estimate before starting work and offer convenient scheduling to minimize downtime.
• Choosing our dealership often delivers faster, more reliable service because factory-trained technicians use OEM parts and validated repair procedures.
