Brake Antilock Control Unit/module problems of the 2007 Lexus Rx400h

I am the original owner of a 2007 Lexus RX 400h which has not been involved in any accidents, and currently has approximately 30,000 miles on it. Since I purchased the vehicle I have noticed an irregularity in my braking system under certain conditions, which is exactly what I heard described this evening on the news about pruis hybrid vehicles. It can simply be described as when braking, if a pothole or bump in the road is hit, or some other small irregularity in the road surface, the car seemingly jerks forward/accelerates for a split second. The feeling is of a momentary loss of control of the vehicle, and has happened while slowly approaching a stop sign or braking/decelerating in traffic, but not typically when slowing at higher rates of speed. I have had these experiences. . . Where I have been slowly approaching a stop sign, braking, when I have hit a small bump, and was not able to stop the car before the stop sign, and in slow moving traffic where I lost momentary control over the car as the brakes "hiccupped" over a rough spot on the road and lurched at the car in front of me. I was just about to make an appointment with my local Lexus dealer, Lexus of austin (texas) regarding my concern when I saw this evening's news. It compelled me to notify you. It looks as though this problem may be more widespread with all Toyota products.
