What could be causing a knocking noise in my Kia Rio's engine?

I recently noticed a knocking noise coming from my Kia Rio's engine while I was driving. It seems to be getting worse and I'm afraid it could be a serious issue. Has anyone experienced this before and knows what could be causing it? I want to make sure I get it fixed before it gets any worse.

One possible cause could be worn engine bearings or rod bearings. It's important to get it checked out by a mechanic as soon as possible to avoid further damage to the engine.

Another possibility is a loose or damaged belt in the engine. This can create a knocking noise and should also be checked by a mechanic.

In some cases, the knocking noise could be caused by low oil levels or dirty oil. Make sure to check your oil levels and get an oil change if needed.
