2013 Chrysler Town And Country cruise control problems

Tl* the contact owned a 2013 chrysler town and country. The contact stated that while applying pressure to her brake pedal to the park the vehicle, the vehicle began to move forward on its own at high rate of speed. The contact began pumping the brakes to no avail. The contact was steering the vehicle trying to avoid impact with an apartment building. Red and yellow warning lights began flashing as the vehicle proceed to jumped the curb and crash into the apartment building.

I'm not sure what exactly happened, the vehicle is pending investigation. I attempted to stop the vehicle, pressing the brakes down as hard as possible, and the vehicle wouldn't stop. The other vehicle was hit from behind at a light I was probably going around 40 MPH. Also, when we first bought the vehicle it had a habit of turning off while driving. Finally got that fixed. It turned out to be the master power cylinder or something like that.
