Creaking sound as coming to full stop

[IggyStooge]

I own a 2013 P85. The car makes a loud creaking sound wherever I come to a full stop. It's from the rear of the vehicle and is not brake-related. (In an attempt to address this problem a few years ago Tesla replaced the brakes.) I can easily reproduce this embarrassing sound by allowing the car to inch forward before breaking. Warm, cold or wet weather makes no difference. Any thoughts on the cause before I take the vehicle in for servicing?

Do you have 21" wheels?

Yes, 21 inch. (Sorry about the slow response.)
