2008 LEXUS RX Vehicle Speed Control Problems

I put my 2008 Lexus in reverse and had my foot on the brakes the entire time as I was on an incline. Suddenly , without provocation, the car propelled backwards and as much as I pumped the brakes, the car continued to hurl backwards full speed. I crashed into another car in my driveway, and finally got the car to stop after suffering a lot of damage. Thank you.
