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

I've noticed that my Kia Rio's engine has been making a strange noise while I'm driving. It sounds like a rattling or knocking noise. Can you help me figure out what could be causing it?

This could be caused by a variety of factors, including worn out spark plugs, a faulty starter motor, or a loose belt. I would recommend taking your Kia Rio to a trusted mechanic to diagnose the issue and make any necessary repairs.

I had a similar issue with my Kia Rio, and it turned out to be a problem with the engine's timing chain. I would recommend taking it to a Kia dealership for a proper diagnosis and repair.

I hear you! I've had my Kia Rio for a few years now and I've noticed a similar noise lately. After doing some research, I found out that it could be caused by low engine oil levels. Give that a check and see if it helps. If not, it's best to bring it to a mechanic.
