Why is my Kia Ceed's engine making a knocking noise?

I recently noticed a knocking noise coming from the engine of my Kia Ceed and I am concerned about it. Can you please provide some insight into what could be causing this issue and what steps I should take to fix it?

The knocking noise could be a sign of an engine problem. It is important to have it checked by a mechanic as soon as possible to prevent further damage.

It could be due to low oil levels or old and dirty oil. Try changing the oil and see if the noise persists. If it does, take it to a mechanic for further inspection.

The knocking noise could also be caused by a faulty engine bearing. This is a serious issue and should be addressed immediately by a professional.
