2009 Nissan Altima brakes problems

A nightmare while awake. While backing out of a bank parking lot I hit a pole lightly. I stopped the car before shifting into drive. When I accelerated the car lurched forward at a fast speed. I tried braking but the car kept going forward slamming into the back of a parked SUV with the driver inside pushing it from the parking space up onto the side walk. And side swiping a parked truck pushing it into the SUV passenger side.. The acceleration was so great I am so my car is totaled.

I was trying to start my car and it would not start. The switch which allows the car to know you are pushing the brake did not work (push button ignition). I tried to put my key in the slot to start the car, but the car does not start if the car does not sense the brake is being pushed. This is a huge hazard. Good thing I was not stranded somewhere. I called nissan with no help at all. A search on the internet revealed this is a problem that has not been addressed. The part number replaced is intermotor sl2110.
