Air Brake Antilock Control Unit/module problems of the 2010 Toyota Prius

Bought this car certified used from Toyota dealer in mid-may 2013. First Prius I've owned, and not used to driving it, so the first couple times it 'lurched forward' with the brakes on, I was surprised, but figured it was just related to the 'hybrid'. It happened again last week at a stop sign with rough road - braking, hit bumps, and brakes disappear! took it into dealer this morning, and they're saying it's 'normal'. Then I start researching and while car is not included in any recalls, it's the same problem investigated in ntsb 10v039000. Exactly! car is still at dealer, as I have asked to speak to service mgr. And just in news today, supreme court is allowing calif 2010 Prius owners to sue Toyota over a bogus fix for this problem. Not sure what to do, but not going to let up on this. Half dozen times in 4 months this has happened, and I like the feeling less every time. Anything I can do? (when you all get back to work).
