I have an appointment this afternoon for the brake recall. When I mentioned the brakes pulsating and having a mind of their own when I go in reverse, the service rep. said he never heard of that. I have read about others on this forum having the same issue. Have you had your problem fixed?
I suggest you take the car with the service rep for a test drive. You drive it (since you know the condition / circumstances) and let them drive it if necessary. Good luck,
You may find the recall chart posted by Tony Schaefer useful: http://priuschat.com/forums/newbie-forum/announcements.html
Some have found that after the sw upgrade, the reverse braking issue went away. I'd get it done and then recheck for the condition.
