Why does my Kia Soul's engine make a knocking noise?

I recently noticed that my Kia Soul's engine started making a knocking noise. It's not very loud, but it's noticeable. Is this something I should be worried about? What could be causing this?

It's likely that your engine is experiencing a misfire, which could be caused by a number of things such as faulty spark plugs, a clogged fuel filter, or a malfunctioning oxygen sensor.

If you've recently had an oil change, it's possible that the wrong type of oil was used, which could also cause knocking noises in the engine.

To be safe, I would recommend taking your Kia Soul to a certified mechanic for a diagnostic test. It's always better to catch and fix any potential issues before they become major problems.
