I wanted to alert you that other hybrid models that were manufactured with the same braking system as the prius suffer the same issue. I have a 2010 Lexus 450H Rx and its brakes disengage when I am driving on bumpy roads and over pot holes. I live in a northeastern city with many bumps and my brakes stop working often and as a result I have to slam them on much more quickly. Although I haven't had a crash at this point, I can easily see running into the back of a stopped car in front of me if my brakes disengage at the wrong time. This is a continual issue and I don't have a specific date but given the prius recall, I am confused why my own brakes have not had a similar software fix and the issue sound exactly the same. The date below is non specific. I have had the car from Dec 2009 until now and the issue has been continuous. The brakes appear to work fine on smooth roads.

Lexus hybrid SUV 2010 rx450H. Car was in snow setting and when I tried to brake on a light snow surface, there was no response from the brakes and I also was unable to steer. I continued forward until I reached clear pavement and was then able to brake. This happened 3 times today under the same conditions. Luckily no cars were coming or I would have been hit broadside on a busy street.
