Before trying to describe this, I'll make clear that I've been driving the car almost 8 months and it's happened exactly three times. So I can't replicate it at will, and my description may be not that helpful. If anyone asks me a question that requires listening for it again, it might be months before I have another chance.
Sill, I'm wondering if this sounds familiar to anyone:
While slowing and beginning a low speed left turn (10 mph maybe?) on good paved streets, there will be a startling noise in the right front corner of the car and a moment of sudden deceleration. The noise might be described as grinding or ratcheting, but it hasn't quite sounded like metal on metal to me. I could even believe it was a strong burst of anti-lock braking being automatically applied to one wheel. Each time the symptom went away within a fraction of a second, the car rolled freely again, and I was able to check behind me to make sure I didn't just come across some kind of road hazard. In each case the road was clean.
On at least one of these occasions, a message flashed briefly on the console. I am not sure of the exact words but it was something like "not available: poor conditions" without telling me *what* exactly was not available. It could have meant the ProPilot system, I guess. The most recent time this happened (yesterday) I didn't see a message on the screen. It's possible ProPilot wasn't switched on at the time.
