After applying force to the brake pedal several times the vehicle suddenly came to a stop. The contact planned to notify the manufacturer and dealer regarding the unexpected brake malfunction. The approximate failure mileage was 17,500.

When the car reached 15-20 mph (the doors lock) a rattling, clunking noise occurs in the rear of the car. This happens every time the car is started and that speed is reached. I was told from the dealership this is normal.

Upon the car reaching 20 miles per hour the anti-lock brake system charges up. This creates a lot of noise and cause the accelerator and brake pedal to vibrate. This condition occurs once every ignition cycle.

The vehicle has had issues with ABS actuator making noises and vibrating. Dealership could find no problems, but referred to Nissan service bulletin. On February 2, 2011, I was traveling at approximately 20-25 mph. As I approached a red light I attempted to depress my brakes. At that time the pedal traveled more than 3/4 of the way to the floor almost instantly. There was a loud metallic clanking and grinding sound and a very strong vibration coming from under brake pedal. I almost lost control of my vehicle as it pulled to the left and almost traveled into the oncoming lane. After 2-3 seconds I regained the use of my brakes.
