Hint: Use a descriptive title for your new message
If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

Personally, I don't trust phone audio to properly represent how loud something is. If it's loud, it's wrong. If it isn't, it ain't.

There is something wrong there. Tell me, if you place the car in drive, then reverse (NOT moving away) is the noise the same/different/gone?
There should only be a momentary slight hum as the electric motors either apply or remove pressure from the brake pads!

I will try the drive, then reverse. But I do know it only clunks when the brake caliper/pads let go of the rotor. It will make the humming/whirring noise after shifting out of park, as it releases the brake, but the caliper remains stuck to the rotor until the car moves. then lets go with a clunk, but not all the time. Almost like the brake pads are frozen to the rotor, but it's always in a heated garage. Maybe snow melts and rusts the pads?

Could very well be indeed. Back in the day my shop installed all kinds of aftermarket (go fast stuff) brake pads. Many had a higher metallic composition than the factory brake pads.
Brake rotors are indeed similar to railroad tracks. They lightly surface rust when wet and put away. One or two applications of the brake pads and it's gone.
Some types of brake pads can INDEED temporarily stick to the brake disc as a result of oxidation.
The noise could be (??) the pad forcefully being pulled away from the inside surface of the disc.
Tell me; Genuine Kia pads & rotors, OEM or aftermarket?

The car has 11,000 miles on it, all original parts. Seems to only make the noise when shifting to reverse, but that could be because we back out of the garage, so maybe we are not aware of the noise when out of the garage and shifting to drive.
