Brake Antilock Control Unit/module Problems of 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.

When braking, any small bump, particularly on wet surfaces, causes braking to cut out for a second or two, and the car does not decelerate as fast. Added pressure is required to engage the regular brakes to resume the same stopping level. This non-linear stopping characteristic causes increased stopping distances and loss of control in braking (at least for a second or two). This seems to be caused by the regenerative braking cutting out when the anti-lock system engages momentarily.
