Why does my Kia Sorento's check engine light keep coming on?

I recently purchased a Kia Sorento and the check engine light keeps coming on. I've taken it to the dealership multiple times, but they can't seem to fix the issue. Is there anything else I should be checking or doing to resolve this problem?

It's possible that there is an underlying issue with your car that the dealership hasn't been able to diagnose. I would recommend getting a second opinion from a reputable mechanic.

Make sure to check your gas cap. Sometimes a loose or faulty gas cap can trigger the check engine light. Tightening or replacing it may solve the issue.

If you've recently filled up gas, it's possible that the gas cap wasn't secured tightly enough. I would also suggest checking all your fluid levels to ensure they are at the appropriate levels.
