Why is my Kia Rio's engine making a knocking noise?

I have noticed that the engine in my Kia Rio has started making a knocking noise. It doesn't happen all the time, but when it does, it's quite loud and concerning. What could be causing this issue and how can I fix it?

The knocking noise from your engine could be caused by a few different things. One common issue is low oil levels or dirty oil. Make sure to check your oil levels and change your oil regularly to prevent this problem.

Another possibility could be that your spark plugs are worn out or not functioning properly. This can cause the engine to knock. Consider replacing your spark plugs to see if that resolves the issue.

If your engine is knocking consistently and loudly, it could be a sign of a more serious issue, such as a damaged connecting rod or bearings. It's important to have this checked by a professional mechanic to avoid further damage to your engine.
