Why does my Kia Picanto's engine make a knocking noise?

I have recently noticed that whenever I start my Kia Picanto, the engine makes a loud knocking noise for a few seconds before it goes away. What could be causing this issue?

The knocking noise in your Kia Picanto's engine could be caused by a variety of issues such as worn bearings, loose timing belt, or low oil pressure. It is important to have a professional mechanic inspect your vehicle to pinpoint the exact cause and prevent any further damage to your engine.

One possible cause of the knocking noise could be dirty or low quality fuel. Try using a fuel additive cleaner or fuel from a reputable gas station to see if it makes a difference in the noise levels. Additionally, make sure to keep up with regular oil changes and maintenance to avoid any potential issues.

I had a similar issue with my Kia Picanto and it turned out to be a loose exhaust pipe. The knocking noise was caused by the pipe hitting against another part of the car. I suggest checking the exhaust system for any loose parts and getting them tightened or replaced if necessary.
