Why is my Kia Ceed engine making loud noises?

I recently purchased a Kia Ceed and after a few weeks of driving, I noticed that the engine made loud noises. I've checked the oil levels and everything seems fine. What could be causing this issue?

It's possible that your engine's spark plugs are worn out and need to be replaced. This is a common issue that can cause loud noises in the engine.

Another potential cause could be a loose heat shield around the exhaust system. This can cause rattling noises while driving.

If your car is equipped with a turbocharger, it's possible that the noise is coming from there. It's recommended to have a mechanic check it out to make sure everything is running smoothly.
