I get a noise and my friends 2014 automatic has the same noise, it is a like a"creak" when you are going slow (creeping) and it is related to hitting the brakes. Like you can hear it in a drive-through (because wall reflect sound) or pulling into a garage.
Not sure if this is what you're hearing just throwing it out there.
