Pulling into a parking space, using reiterative braking (B Mode). When applying brakes, car bolted and could not be controlled. It jumped a curb and drove straight toward a building. Brakes would not respond. Steering would not respond. I managed to steer the car avoiding the building but taking down a bench and ripping up the turf in front of the building. Car made a complete u-turn before coming to a stop. At that point, all electrical systems shut down, including the outside mirrors--they retracted. There was damage to exterior of the car-- a torn side molding and scratches and minor dents from bushes and the bench that was destroyed. The infotainment completely shut down. when I finally was able to restart the car, the systems came back on slowly, one at time. The car was towed by VW Roadside Assistance to a collision center for body repairs. It will be towed to the dealership after body repairs to diagnose the problem. I did not want to drive the car, not knowing if it is safe to drive. I had to file an insurance claim for the damage to the car and to the property that was damaged in the process. No other cars were damaged.
