Why does my Kia Picanto make a rattling noise when I start the engine?

I've noticed that whenever I start my Kia Picanto, there is a strange rattling noise coming from the engine. What could be causing this and should I be concerned? Is there a way to fix it?

The rattling noise could be due to several reasons, such as loose or worn-out belts, low engine oil, or an issue with the engine itself. It is always a good idea to get it checked by a mechanic to determine the exact cause and get it resolved before it turns into a bigger problem.

I had a similar issue with my Kia Picanto and it turned out to be a loose belt. I would suggest getting it checked as soon as possible to avoid any potential damage to the engine.

If the rattling noise only occurs when you start the engine and goes away after a few seconds, it could be due to the pistons and valves adjusting to the oil pressure. This is a normal occurrence and nothing to worry about.
