I started to describe it as a drone, but it is a higher pitch than a drone. I also would not describe it as a screech or metal sound. As far as reproducing, I would need to take a few dealer employees for a ride to the lake. ?

Hello All, I picked up a new 2019 Lincoln Navigator L Reserve. I now have about 2000 miles on it. Starting this week I heard a ear piercing harmonic noise. I can reproduce it at will. 4 large adults in the front 4 seats and 3 13 your old kids in the last row. When I go down an incline coasting and slowly slowing from 68 - 65 I hear a bad harmonic noise. It is coming from the back. I am not sure if it is coming from the transmission, Drive line, or the differential. Before I send it to the dealer, is this a common problem? I did a search on this forum and did not find anything. I found 1 mention of something similar on a untrusted to me site. The only way I can reproduce it is by the passengers mentioned above in the vehicle.
