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

I recently purchased a Kia ProCeed and noticed that the engine is making a loud knocking noise. Should I be concerned? What could be causing this issue?

It is important to get your vehicle checked by a mechanic as soon as possible. The loud knocking noise could be a sign of a serious mechanical issue that needs to be addressed.

One possible cause of the knocking noise could be low oil levels. Check your oil regularly and if it is low, make sure you top it up.

Another common cause of engine knocking is dirty or old oil. Make sure to stick to your vehicle's recommended oil change schedule to prevent this issue.

You may also want to have your spark plugs checked. Worn out spark plugs can cause knocking noises in the engine. Replace them if necessary.
