Anyone know what this sound could be?

I'm taking to the dealer this morning. The sound is very intermittent and I suspect they are going to tell me they could not duplicate. It usually happens when the car is warm and when it is coasting. Any ideas?https://youtu.be/EHP1X5PIlcM

Curious as to your findings. I have same exact sound intermittently as well. Sounds to me like something in suspension.

I believe it may be the rear differential.

I recall seeing a post and some videos of it.

This is super helpful! I will let the dealer know to check out the rear diff.

The dealership has told me they cannot duplicate the problem. No surprise there. I gave them all of the information given to me and am waiting to hear back. They are also going to do an extended test drive. I'll update once I know more.
