I was parked at a stop light facing down a slight hill. The car suddenly accelerated and crashed into the car in front of me. Afterwards, upon inspection, it is possible while at idle to depress the brake pedal with a little bit of pressure to the floor. My foot must have hit the accelerator while the brake was slowly being depressed. The harder I tried to brake the faster the car went. I visited the Audi dealer and we tried this experiment in a similar model with the same result. The dealer says this is part of the design! it is not possible to do this in my other car or other models I have checked. I believe it is an extremely dangerous design and could have resulted in a very serious accident if there was no car just a few feet in front of me.

After slowing for a left turn from main thoroughfare to side street, my brake pedalfailed to depress to slow the car down. I had to allow the car to coast to a slower speed and then to a stop. After clearing snow from the wheel wells and allowing the car to sit with the engine off for approximately 20 minutes, the brake pedal "unlocked" and I was able to depress the pedal once more.
