Why does my Kia Sportage engine make a knocking sound?

My Kia Sportage's engine has been making a loud knocking sound lately. What could be causing this and how can I fix it?

First, make sure to check your oil levels. Low oil can cause knocking sounds in the engine. If the levels are low, top it off and see if the knocking goes away. If not, it could be an issue with the engine itself.

Another possible cause of knocking sounds in the Kia Sportage engine is worn out spark plugs. Check and replace the spark plugs if needed.

If the knocking sound continues, it could be a sign of a more serious issue, such as a faulty connecting rod or piston. It's best to take your vehicle to a professional mechanic for further diagnosis and repair.
