SOLUTION: Dealership informed me today that problem is the "shark fin" satellite radio antenna mounted on the roof. They state that when they applied forceful air to the shark fin, that the noise could be heard on the inside of the car while parked. The suspect that shark fin is allowing air underneath it, therefore creating a "whistling sound" inside the vehicle. They suspect that fin has a gap underneath it, and the gasket between the roof exterior and interior may be the culprit.
Tell them if they want to replace the antenna, and it doesn't cure the problem, then you're not paying for it! Let's see how confident they are with their diagnosis then!

Sorry to resurrect an old thread, but I am having this exact same issue on my 2014. I love the car but this is driving me crazy. I've already spent around $1k at the dealership and the noise has not stopped. The shark fin/bracket etc have already been replaced. The fin sits tight now (it didn't before). We thought we had it fixed after 3 visits to the dealership, but we don't. The hard part about the issue is the noise is very inconsistent....it's like I have to be driving with the perfect cross wind to hear the noise. When it makes the noise, it sounds like a massive hive of bees or whistle coming from the center rear of the roof.
Does anybody have a fix? I am starting to wonder if the noise is coming from the center brake light near the shark fin. Perhaps the weather stripping is bad?

Try treating all the seals with Gummipfledge or Shin Etsu grease

Try taping over those seals back there with thick painters tape and see if that solves it, that will help you identify those seals...

Is this part of a routine..like a commute? Have you ruled out different conditions of asphalt or concrete because the differences in some surfaces will cause more road noise than others. Have you yourself tried riding as a passenger with another driver to identify where the noise is coming from ?

Humans who have good binaural hearing are very good at localizing sound sources. Have 2 or 3 of your friends/associates ride with you and ask them to point to where the sound is coming from.

The upper brake light area is the only area I have not touched (nor has the dealer).

I taped the shark fin before and thought I found it prior to the work. I did it again with the dealership (head tech) in the car and he thought it was the fin as well. They test drove it after the fix with no noise...but it's back. The intermittent part is what makes it so difficult.

I'll have to try that over the brake light seal next. I try to wait until I hear the noise, pull over and tape it and get back on the same road. I think this gives me the best shot of isolating the noise. I did this with the fin and would have sworn (and paid money) to fix the shark fin. I guess it changed the wind just enough to temporarily solve the issue.

Probably no chance when the car was at the dealers they tried different wheels and tires from a used unit, not saying that's what it is but resonance/vibration from wheels or tires can do some funny stuff.
