Why is my Kia Sportage's engine making strange noise?

I've noticed that my Kia Sportage's engine has been making a strange noise recently. It's not a constant noise, but it's there every now and then. What could be causing this and should I be concerned?

It is possible that there could be an issue with the engine's bearings or pistons. It's best to have a mechanic take a look at it to diagnose the specific problem.

Another possibility is that there could be a problem with the exhaust system or muffler. It's important to have this checked out to prevent any potential issues or hazards.

Make sure to keep an eye on your engine's oil levels and change it regularly. Low or old oil can also contribute to strange noises coming from the engine.
