Is this the dreaded propeller shaft whine?
I made a short video clip (link below).
~30,000 miles on the odo. This just started happening, and only when it's very cold. Seems to be road speed dependent, not engine speed or load or gear. After a minute of driving, it goes away. I have an appt with my dealer to leave it overnight and have them drive it after sitting out all night.

OP....Yup....I am not a mechanic but I would say that its the dreaded propeller shaft. I am happy that you have some warranty left.

Update... I brought it in Thursday and I left it over night so they could drive it cold. Unfortunately, we've had a bit of a warming spell such that when they drove it the temp was around 30F, so they didn't get the whine sound. I've only heard it with temps around 15F or colder, and then only for a brief time (until the car warms up, I expect).
BUT, when I brought it in they asked if there were any other issues and I told them about a clunking from the back right I'd hear when going over snow compacted roads or rough roads, and it was worse in the cold. I figured it was cold bushings and expected with the stiffer suspension, but if they put it on the lift could they have a look-see. Come to find out, it has a broken strut. I forgot to ask what they mean by "broken".
The SA was a little reluctant to let me have the car back until it was fixed, and that won't be until Tuesday when he gets the part. Until then, we are expecting colder temps, so he said they would see if they can replicate the whine I recorded.
They gave me a 2014 SH-AWD Tech to drive in the mean time, so I'm not feeling any hardship.

Also had the same problem I went through 2 prop shafts... Best way to determine if its the prop shaft - have them remove it and drive it . It wont damage the car - car acts like a FWD car....

When my TL started making a whine sound, I took it to the dealer and explained the problem in detail. The service writer said he never heard of a problem with prop shafts. I replied that "it will not take much time to put it up on a lift, so please humor me and put a listening device on the 3 support bearings when it is turning and tell me what you hear". He came back a half hour later and said he was surprised to confirm that one of the bearings was bad.
Checking for the tell-tale sound is harder to hear from the inside while driving. Have them check while on the lift running & in-gear. That way the bad bearing sound is not masked by road & wind noise.

Final update...car is back with a new prop shaft and a new rear strut. Nice and quiet, and they washed it.
The strut took the longest... they had to order it and it took 5 days. They gave me a 2014 SH-AWD Tech for the week, so I really wasn't inconvenienced. I drive by the dealership daily on my way to work.

Just had mine replaced in my 2012 awd..took one day..the service manager said they have replaced a couple but acted as if he had never heard of the issue..I think he was well aware I wasn't going to stand for being bs'd on this and had done my research..took it on a test drive and of course it didn't want to make the noise in the beginning but once I held it at 80 and then hit the off ramp sure enough there it was..constant between 20-40 mph..really makes the car sound like $-it..they gave me a 2014 RLX for a loaner..it is quite nice..but too many bells and whistles for me..barking at me about lane veering and braking if it felt I was too close to the car in front of me and such..just too much..to be honest I'm a very aggressive driver but smooth and methodical about it as well..it's like dancing with cars so I found the alerts very annoying..it's very very spacious and I was impressed with the power..still tho I think I'm 20 yrs too young for that car..also it is a very nice looking car in person..that seems to be a trend with this line up..not much in a pic but standing next to it it is completely different..nevertheless they took care of the issue no problem and replaced my passenger door floodlight or whatever you wanna call it under warranty..washed it as well..all in all a very positive experience..well done Acura of Johnston..well done.

Bought my '12 SH-AWD from a Toyota dealer last month with 39k on it. Shortly after purchase I began hearing noise. Not really a whistle or whine, more like crickets chirping. Heard it when I hit 20 MPH. Scanned these forums to learn about the propeller shaft issue. I called my local Acura dealer to describe the issue. Instead of saying I read about the issue online, I told the Acura dealer that Toyota diagnosed the sound and told me to see Acura dealer because the car was still under new car warranty.
Upon arriving at Acura dealership, a tech and I took a short drive to replicate the sound. The tech agreed that it was the Prop. Shaft. They replaced the part , which cost $1200, for free the same day. So far no more noise.

So what happens when you leave the problem? The whine happens more often and that's it?
Also it looks like there's two versions:
40100-TK5-A01
and
40100-TK5-A02
Am I right in assuming the A02 is the newer one that has the issue fixed?

If the propellor shaft is removed, would the dash display for the AWD distribution show that? Meaning it would have no progress bars for the rear wheels? Or is that more of what the car should be doing.

It still showed power going to the rear wheels but I could tell from pulling out a little quick that the rear wheels were not getting any.
