Why is my Kia Ceed's engine making strange noises?

I have noticed that my Kia Ceed's engine is making weird noises lately. It sounds like a rattling or knocking noise. What could be causing this and how can I fix it?

This could be due to a loose or damaged belt in the engine. It's important to have it checked by a mechanic as soon as possible to prevent any further damage.

It's possible that there is an issue with the spark plugs or ignition system. This can cause strange noises in the engine. I would recommend taking your Kia Ceed to a trusted mechanic for a diagnostic check.

If you have recently filled up with low-quality or contaminated fuel, this could be causing the noises. I would suggest draining the fuel tank and filling up with a higher quality fuel.
