2006 Nissan Maxima cruise control problems

Dt*: the contact stated on reversing the vehicle out of a parking space, the front end was not clear of the curb. When drive was engaged and the accelerator was depressed, the front left bounced over the curb. As this happened, a metallic bang was heard, then the vehicle accelerated forward out of control. The steering would not respond and the vehicle drove over another curb knocked down a sign post and then on impact of a stone pillar, causing all airbags to deploy.

Unintended acceleration 3 times, each more violent then the first time, of a new 2006 nissan maxima, only 26,000 miles on it, this is the 3rd. Time it has happened, on sept. 18, kahului, maui. Terrifying, I could not stop the car at the stop sign of intersection, this was the worse of the past two accelerations that I had with this car. My husband was with me on the passenger side of car. It took off like a "race car" I could not break it or stop car from going.
