Why is my Kia Picanto's engine making a knocking sound?

I have a Kia Picanto and every time I start the engine, it makes a loud knocking sound. What could be causing this issue? Is it something I should be worried about?

It is possible that the knocking sound could be caused by a lack of proper engine oil or a worn out oil filter. I would highly recommend checking your oil levels and replacing the oil filter if necessary.

Another possible cause for the knocking sound could be worn out spark plugs. I suggest replacing them to see if it resolves the issue.

If none of the above solutions work, it is best to take your car to a mechanic for a thorough inspection. The knocking sound could be a sign of a more serious engine issue.
