I've got the same issue with my 2016 CX-5 Grand Touring AWD. Brakes only squealing from the rear when lightly applying the brakes and at slow speeds. Also, when releasing the brakes at 0mph and allowing the car to roll forward, there is a squeaking noise when the wheels start spinning (no brakes applied).
First experienced the problem with about 7k miles on it, told Mazda Dealership about the issue and they told me they looked fine. Complained about it at my next service and they told me they needed to order new pads for it. Went to the dealer once the new pads arrived and they sent me home telling me the 2016 uses a different pads than the 13-15 models. They ordered the correct pads, replaced them, squeaking went away for about 3k miles. Took it back, they told me there was a bulletin from Mazda about it, but the bulletin said that the problem only occurred when the brakes were worn, not new brakes like what I had. They told me that the brakes are harder and that's why they may be squeaking, so that they last longer. I put a complaint in to the Manager of the dealership and he said he would call Mazda and call me later in the day. He called me and told me he spoke to Mazda and there are 0 complaints for 2016 for the issue I am having and they will change out the rotors and pads, but there is no guarantee that it will resolve the issue.
I had the 2014 CX-5, never had this issue, I put about 50k miles on that before upgrading to the 2016 model. I now have 20k miles on the 2016. I do drive a lot, but the car is less than a year old, 85% highway driving.
I'm scheduling my rotors and brakes to be replaced. Will post an update of the results; I'm hoping that fixes the issue.
