Why does my Kia Picanto engine make a loud knocking noise?

I recently bought a Kia Picanto and after driving for a few weeks, I noticed that my engine started making a loud knocking noise. This noise gets even louder when I accelerate. What could be causing this issue and how can I fix it?

It is likely that there is an issue with the engine's spark plugs or timing belt. I would recommend taking your car to a certified mechanic to have it checked and replaced if necessary. It's important to address this issue as soon as possible to avoid further damage to your engine.

Another possible cause for the knocking noise could be a lack of oil in the engine. Check your oil levels and if they are low, make sure to top it up. If the noise persists, it's best to bring your car to a mechanic for a professional inspection.

Have you been driving your Kia Picanto for long periods without changing the oil? If so, this could be the reason for the knocking noise. I would recommend getting a full oil change and also replacing the oil filter to ensure proper lubrication for your engine.
