Why is my Kia Rio making a knocking noise?

Recently, my Kia Rio has been making a knocking noise whenever I am driving at low speeds. I'm not sure what could be causing it, but it's starting to worry me. Any ideas on how to fix this?

It's possible that your engine oil level is low, causing the engine to make knocking noises. Try checking your oil level and topping it up if necessary.

Another possible cause could be faulty spark plugs. If they are worn or dirty, they can cause your engine to make knocking sounds. Consider getting your spark plugs replaced or cleaned.

Have you noticed any other symptoms besides the knocking noise? It could be an issue with your suspension or wheel bearings. I recommend taking your Kia Rio to a mechanic for a thorough inspection.
