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).

The contact owns a 2010 Toyota Prius. The vehicle was included in the recall under NHTSA campaign id number 10V039000 (service brakes, air:antilock:control unit/module) and had the repairs performed. The contact stated that after the repairs were performed, while driving approximately 15 mph over a uneven road surface, the brake pedal was depressed and the vehicle suddenly accelerated for a few moments. The contact also stated that the failure only occurred when driving over an uneven road surface. The vehicle was taken to an authorized dealer for diagnostics, where the technicians were unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 100. The VIN was not available. Had the recall done but it did not fix the problem. Toyota has been unresponsive and the dealers say there's nothing they can do. Updated 11/16/2011
