Can anyone help me figure out what this sound is

Sounds like the high-pressure pump or injectors. They can be quite noisy.

I have a 2021 K5 and it makes the same noise.

High pressure fuel pump?

Sounds like a Kia. Just wait until you hear the real knocking.

Is your oil level full? Sounds like valve tapping.

How’s your oil level?

That sound is just a noise.

This is a Kia K5 GT Line 2024. Can anyone help me out?

I had an issue with my 2023 Sportage where there was a service bulletin that required the fuel line to be rebuilt. You might want to take it to the dealership to get it checked out.
