Why is my Kia Ceed's check engine light on?

My Kia Ceed's check engine light just turned on and I'm not sure why. It's never happened before and the car seems to be running fine. What could be causing it?

The check engine light can turn on for a variety of reasons, ranging from a loose gas cap to a more serious engine issue. It's important to get your car checked by a mechanic as soon as possible to determine the cause.

I had the same issue with my Kia Ceed and it turned out to be an issue with the oxygen sensor. Take it to a trusted mechanic and they'll be able to diagnose the problem for you.

Don't ignore the check engine light, even if your car seems to be running fine. It could be an early warning sign of a bigger issue that could end up costing you more in the long run. Get it checked out.
