2013 Nissan Versa engine problems

I was drviing my car on greenbelt rd, md, and noticed s stange low noise or sputtering..of some ssort. I decided to stop the car...however car did nto stop...I put in park, turned engine off...did not stop...I uesed emergency brake...did not stop...I felt it accerelated on its own..and had loss of brake effectiveness. I sounded the horn loudly to warn people. But the car kept going and going. I am a single mom, and my child was with me...for safety of life and property... I intentionally drove into a ditch.

1. From the beginning, wind noise was noticeable. Management from dealership checked vehicle and said noise was from design of side mirrors. I called nissan and they said there were no bulletins at time and until there were they could do nothing. 2. Windshield has waviness across entire lower section of glass. This is noticeable where glass and cowling adjoin. New windshield was order from nissan and installed. Same issue with replacement glass. My wife is 4'9" and finds this to be distracting. 3.
