TSB R052/16C - Noise from REAR BRAKE/Trace of Rear Brake Dragging
You should start calling Customer Experience Center at Mazda North American Operations and trying to get this issue resolved. It is NOT normal!

Your problem should be caused by something sticky such as caliper pins or calipers themselves. If your 2017 Mazda3 has Electrical Parking Brake (EPB), you could have the same issue like 2016 CX-5 which may exhibit the rear brake dragging resulting in brake noise and the outer disc pad abnormally worn out:I am having the same problem with a 2017 3 hatchback. It has been to the dealer 4 times to fix the problem. It makes a groaning/creaking noise during low-speed braking (parking). Also when coming to a full stop at normal speeds. (stops, seems to make the sound when the car "rebounds" from a normal-effort full-stop) I thought at first it was suspension related, since it did sound like a suspension creak. Happens no matter what the weather is, or hot/cold brakes. Dealer tells me it is a brake noise. And it is "normal" for this car to make that noise. It started in a couple of months ago (23k miles now). I have never driven any car, owned, rental or otherwise that made such a noise. So I can't take this as "normal". It is really loud. Not a scraping sound (like rusty disks or worn pads). Also, if I am stopped in a parking lot, and I release the brakes really slowly, I can get this continuous noise, the vehicle not moving, this groan/creak/whine kind of noise, can get it to go on for 30 seconds with no motion of the vehicle (in gear). One of the dealer mechanics said it could be due to the "city braking" system/option that warns/applies brakes at low speed, pre-loads the calipers. But it shouldn't whine about it.
I think that this is some issue with the calipers. No brake work/replacements have been done, all original equipment under warranty.
Today, to "prove" to me that this is "normal", they put me into a 6 with 2k miles on it. And, yes, I could get it to make that noise also. Again, if this is what Mazda thinks is "normal" brake behavior, it doesn't say much for the brand. I would not expect this kind of issue with a vehicle that is less than 2 years old. None of my ancient Hondas ever made such a noise (first experience with Mazda). As far as I can tell, they have taken no action to attempt to remedy the situation, they just "diagnose" it and do nothing except tell me that it is a noise to be expected.
Any ideas of the real cause of this issue? thanks!
