What is the issue when my Kia Sportage's engine is making a knocking noise?

I've noticed that my Kia Sportage's engine has started making a knocking noise recently. Could this be a sign of a bigger issue? What should I do to address this problem?

The knocking noise could be an indication of engine problems, such as worn-out bearings or low oil pressure. It's important to have it checked by a mechanic as soon as possible to avoid further damage.

This could also be caused by using the wrong type of oil or not changing the oil regularly. Make sure to use the recommended oil and follow the manufacturer's maintenance schedule to prevent engine issues.

I had a similar issue with my Sportage and it turned out to be a faulty fuel injector. I recommend getting it checked and replaced if necessary.
