My 4-month-old car's brakes failed to operate while traveling at 60mph in the fast lane of the freeway. Fortunately I was able to turn on hazard lights and coast across the freeway to the hard shoulder where the car rolled to a stop. The problems began earlier in the day when the car reported "reduced brake pedal feel, ok to drive with caution. Later in the day a message reported "aspc not available." At this point I called the dealership who advised us to bring it in the next day. Some time after this alert we received a series of rapid messages - "traction control offline" "emergency braking assist offline - ok to drive with caution" and several others which I don't recall. The final warning was "gear box fault" - at this point I thought it wise to pull over, but when I tried to use the brakes there was no response at all. Just a grinding, crunching feeling under the brake pedal. I turned on hazard lights and coasted to the right lane through fast-moving traffic, and then onto the hard shoulder. I believe the regenerative braking system was working and this managed to slow the vehicle to a stop. On the hard shoulder I turned the car off and then on again, but the brake pedal still had a grinding, crunching feeling and would not operate. The park/drive/neutral buttons just flashed if you pressed them. I was in the car with two children under 6 and my wife. We were very concerned as there was very little space at the side of the road and no way to get off the freeway. We pressed the car's sos button and the woman advised we call 911 to be rescued by the police. Jaguar roadside assistance sent a tow truck to tow the vehicle to Jaguar monterey for repair. A few days later we were told the car's "power distribution box" had failed. The car had no outstanding recalls. When purchased it had the "aspc not available" error and had to go back to dealer for repair.
