Why is my Kia Rio's engine making unusual sounds?

I recently bought a Kia Rio and I've noticed that the engine makes strange noises when I start it up. It's not a constant noise, but it's concerning. What could be causing this and how do I fix it?

The first thing to check is the oil level in your car. Low oil levels can lead to strange engine noises. If the oil is low, make sure to top it up and see if the noise subsides. If not, it's best to take your car to a mechanic for a proper diagnosis.

Another possible cause could be a loose or damaged belt in your engine. This can cause a squealing or rattling noise. Have a mechanic check your belts and replace them if necessary.

If the strange noise is accompanied by a decrease in engine performance, it could be a sign of a more serious issue. It's best to have a professional mechanic inspect your car to determine the root cause and prevent any further damage.
