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

I recently purchased a 2018 Kia Sportage and the check engine light has turned on. I'm not sure what could be causing this and how serious it is. Any advice would be appreciated.

The check engine light can indicate a wide range of issues, from something minor like a loose gas cap to something more serious like a faulty oxygen sensor. The best thing to do is to take your Kia Sportage to a mechanic or dealership for a diagnostic test. They will be able to determine the specific issue and provide the necessary repairs.

I had the same issue with my Kia Sportage. It turned out to be a faulty catalytic converter. It's important to get this fixed as soon as possible as it can cause damage to your engine if left unchecked.

Check the codes yourself using an OBD-II scanner. This will give you a better idea of what could be causing the check engine light to turn on. You can also try tightening the gas cap and see if that helps.
