Why is my Kia Picanto making rattling noises?

I have recently noticed that my Kia Picanto is making rattling noises whenever I start the engine. It goes away after a few minutes, but I'm worried that something might be wrong. What could be causing this and how can I fix it?

It's most likely caused by loose or worn out engine components such as the belts, pulleys, or spark plugs. It's important to get it checked by a mechanic to avoid potential engine damage.

Check your exhaust system, especially the muffler. Sometimes a loose or damaged muffler can rattle when the car is first started. It's an easy fix, but important to get it checked out.

If you have recently changed your engine oil, it's possible that the rattling noise is caused by a defective oil filter. Make sure to use a high quality filter and change it regularly.
