Why is my Kia Picanto's engine making a loud noise?

I have noticed recently that whenever I turn on my Kia Picanto, the engine makes a loud noise. It didn't used to do this. What could be causing this and how can I fix it?

The loud noise could be due to a problem with your car's exhaust system. It is important to get this checked by a mechanic as soon as possible as it could lead to further damage.

Another possible cause could be a loose belt in the engine. This can be fixed by tightening the belt or replacing it if necessary. It is important to address this issue to prevent any potential breakdowns.

Sometimes, the noise can be caused by low oil levels or dirty oil. Make sure to regularly check and change your car's oil to prevent any engine issues.
