Why is my Kia Stonic's engine making a knocking noise?

I just purchased my Kia Stonic and I've noticed that the engine makes a knocking noise when I accelerate. Is this something to be concerned about?

It is normal for a new car to make some noises as the engine breaks in. However, if the noise persists, it could indicate a more serious issue.

Try using a higher quality fuel. Lower grade fuels can cause knocking noises in the engine.

It could be a problem with the engine's ignition timing. It's best to take your car to a mechanic for a proper diagnosis.
