Odd noise from rear of car on slowing

I have recently received my Tesla and seems to have turned into the worlds largest loop taxi service where I pick people up from their house and drop them back 15 minutes later... A few people whilst on the FOC trips have commented that they have heard an odd noise from the rear of the car that sounds a bit like an automatic handbrake turning on.

My thoughts are that as I have standard re-gen braking turned on its something so do with that as it seems to make the noise when slowing down, approaching roundabouts etc. It sounds almost exactly like the noise an electric handbrake makes and only last for the same amount of time.

Any comments gratefully received.

In my experience, a slight amount of high pitched noise from the newer cars is normal. I can only hear mine when the radio is off and the car is otherwise silent. If you have a "D" car, it's a little worse in Range Mode. I understand it's a little louder in the older cars. If it's really loud, it may indicate early problems in the high voltage system somewhere (like the contactor). There are multiple other threads here about this noise. Some call it the "balloon noise". Do some searching.
