What Your Kia Check Engine Light Means (and What to Do)

A check engine light is your Kia’s way of telling you something REALLY needs a look. Sometimes it’s something minor, like a loose gas cap, and sometimes it’s a repair worth handling soon. Here is what a Kia check engine light means, what to do, and when to bring it in.

What does a check engine light mean on a Kia vehicle?

The check engine light ( The small engine-shaped symbol), means your Kia’s onboard computer has identified a trouble code from one of its sensors. It can point to anything from a simple sensor reading to an emissions or engine concern. The only way to know the exact cause is to read the code, which our service team can do quickly.

Steady light vs flashing light: what is the difference?

A steady check engine light usually means a non-urgent issue you should have checked soon. A flashing check engine light is more serious and often signals an engine misfire that can damage the catalytic converter if you keep driving. If your light is flashing, slow down and have it checked right away.

Can I drive with my Kia’s check engine light on?

If the light is steady and the car feels normal, you can usually drive a short distance. However, please get it checked as soon as possible. If the light is flashing, or if you feel rough running, a loss of power, or hear unusual sounds, it is best to stop and and bring your car to a service shop.

What are the most common causes of a Kia check engine light?

A quick scan pinpoints the cause, but the most common ones include:

• A loose, damaged, or missing gas cap
• A failing oxygen (O2) sensor
• A catalytic converter issue
• A dirty or faulty mass airflow sensor
• Worn spark plugs or ignition coils
• A weak battery or charging problem

Should I just reset the check engine light?

Clearing the light without fixing the cause only hides the problem, and it will usually come back. It can also erase the codes a technician needs to diagnose it. The best practice is to have the code read and the underlying cause repaired so it stays off for good.

Does my Kia warranty cover check engine light repairs?

It depends on the cause and your coverage. Many powertrain-related issues on newer Kias fall under Kia’s 10-year or 100,000-mile limited powertrain warranty. Once we read the code, we can tell you what is covered before any work begins.
