Prius v 2012 "moaning" noise

I really like my 2012 Prius v, but in cool or cold weather, which happens quite often in Seattle, when I first exit my parking spot, there is a “moaning sound”. I have relayed that info to my Toyota dealership and was told that Toyota is aware of the issue but has no fix. I tried contacting Toyota online and have made several attempts to get updated info at my dealership but have had no luck. Has anyone else had this experience with their 2012 Prius v? If so, has Toyota offered you a repair option? Thanks in advance for any info you may have to share.

The noise comes from the rear brakes.

Yes. Toyota is aware of the problem and is working on a fix.
