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

I recently noticed that my Kia Sorento's engine is making a loud knocking noise. It happens when I start the car and lasts for a while, but then goes away. What could be the cause of this? Should I be worried?

It is possible that your engine is low on oil, causing it to make a knocking noise. I recommend checking your oil level and topping it off if needed.

Another possible cause could be worn engine bearings. You may need to have them replaced to resolve the knocking noise.

In some cases, a bad fuel octane rating or using the wrong type of fuel can also cause engine knocking. Make sure you are using the recommended fuel for your Kia Sorento.
