Why is the Kia Ceed engine making a loud noise?

I have noticed that my Kia Ceed engine is making a loud noise when I start the car. It seems to go away after a few minutes but I am concerned that there may be a larger issue. What could be causing this loud noise and what should I do about it?

It is possible that the loud noise is due to a problem with the exhaust system. I would recommend checking the exhaust pipes and muffler for any leaks or damage. If everything looks okay, then it could be an issue with the engine itself.

Another possible cause of the loud noise could be a problem with the spark plugs. I would recommend getting them checked and replaced if needed. If the problem persists, then it could be a more serious issue with the engine.

You may also want to check the oil level and condition of the oil. Low oil levels or dirty oil could also contribute to a loud engine noise. Make sure to change the oil regularly and keep it at the recommended level.
