Why is my Kia Rio's engine making a knocking sound?

Recently, my Kia Rio's engine has been making a noticeable knocking sound while idling. It's becoming quite concerning and I'm not sure what could be causing it. Has anyone else experienced this issue?

It's possible that the knocking sound is coming from worn engine bearings. This is a common problem with Kia Rios and can result in major engine damage if not addressed.

Another potential cause could be low oil levels or dirty oil. I recommend checking your oil level and getting an oil change to see if that solves the issue.

Have you checked your spark plugs? They may need to be replaced if they're worn or damaged. This could be causing the knocking sound.
