2008 Pontiac G5 electrical system problems

Approaching a busy intersection, my pontiac g5's brakes failed to work. I could tell the hydraulics systems was working as I could hear metal on metal but it did nothing to slow down the vehicle. The vehicle's cdr showed the vehicle accelerating at full throttle although I know my foot was on the brake pedal as evidenced by the metal on metal sound. Plus a witness saw smoke coming from my vehicle. I was able to turn prior to going through the intersection and aimed for a fire hydrant to try to slow down.

Tl* the contact owns a 2008 pontiac g5. While driving approximately 40 MPH, the vehicle stalled causing the driver to lose control of the vehicle and crash into a ditch. During the crash, the seat belts failed to retract and the air bags did not deploy. The driver sustained a concussion and upper torso trauma and the front passenger suffered a fractured neck, vertebrae, and a concussion. Both occupants required medical attention. A police report was not filed. The vehicle was not diagnosed or repaired.
