| Description of the problem | Having undergone a previous recall to fix a brake issue several months ago, at 50000 miles on december 23, 2016 the vehicle experienced complete brake failure narrowly avoiding a serious collision. While driving straight on a city street in traffic at approximately 35 miles an hour the driver removed his foot from the accelerator in preparation to apply the brakes to stop the car for the stopped traffic ahead. The car's regenerative braking ability was already slowing the car when the driver's foot attempted to push the brake pedal and found it solid and unmoving. The driver removed his foot from the brake pedal and reapplied his foot, attempted to depress, and again found the pedal unmoving. With the car continuing toward stopped traffic ahead the driver began to repeatedly and very forcefully attempt to depress the pedal. After 4 or 5 very strong kicks the brake pedal broke loose, went all the way to the floor without the drivers pressure, with no resistance or response. The driver retracted his foot and the pedal did not come back up. The driver attempted to begin to "pump the brakes" and with the first touch on the pedal which was still all the way down, the car's wheels locked and came skidding to a stop with no abs modulation inches before hitting the car in front. The car was shut down and restarted, the brake pedal returned to the undepressed position but when depressed had no resistance and was ineffective at stopping the car (as though the brakes were not being applied). The parking brake was unaffected and would slow/stop the car. The car was taken to a nissan dealer for repair, they indicated that they had never seen anything like it and had to talk with the nissan engineers. 1/3/17 the owner/driver was told that the entire "brake brain booster controller" would have to be replaced with a replacement part from the nissan factory in kentucky. |
