What are the common maintenance issues with the Kia Sportage engine?

I have noticed some strange noises coming from my Kia Sportage's engine. What are some potential issues that I should be aware of and what steps can I take to prevent them?

Loud knocking noises from the engine could be a sign of low oil levels. Make sure to regularly check and change your oil according to the manufacturer's recommendations to avoid any potential damage to your engine.

If you notice your engine overheating, it could be due to a malfunctioning cooling system. It's important to get this checked out immediately to prevent any further damage.

Regularly check your air filter and replace it if it's dirty. A clogged air filter can decrease your engine's performance and affect gas mileage.
