my 2015 cmax hybrid has developed a strange noise at highway speeds. As far as I can tell it resembles the revving engine sound you hear as the plane is descending or ascending. It feels like it is coming from the back and it is there both in EV and ICE modes. I am going take it to the dealer but wanted to post here to find out if anyone else experienced it.

Do you have the auto park option?

I also had this creaking issue and it was driving me nuts.  I just got the car back from Ford after completing the door latch recall and all creaking has stopped.  I believe the latches are not holding the strikers tight enough.  Lubricating the trim is just treating a symptom.

That is the door check.  All four of mine have done this.  I believe it is just a plastic coating, nothing to worry about.
