Air Bag Not Deploy problems of the 2019 Nissan Rogue

I was driving a rental vehicle, 2019 Nissan Rogue, 65 mph and when I applied the brakes they failed, causing me to go across the intersection, through a fence, into a ditch. The front end was totaled. The airbags did not deploy. The 4 wheel drive took over and the car pulled itself out of the ditch eventually stopping in a field just prior to going over and embankment and into a river. According to the police officer that arrived at the scene, the brakes of the vehicle were pressed all the way to the floor of the vehicle, although he did not enter this into the written report. He did verbalize that to me on the phone the day following the accident. There were no skid marks on the road indicating that the vehicle tried to stop. I was going the speed limit of 65 mph. I sustained 2 fractures of my back, a concussion and a large laceration of my forehead. The vehicle is currently in storage and has not been inspected, yet. The computer of this vehicle took over and drove itself. I was taken to a nearby trauma center and admitted for 2 days.
