I was driving normally at about 45 mph with no strong acceleration, after about 20 minutes of driving... Then Cross Traffic Alert, Crash Alert, ABS Failure Alert, Parking Brake Fault Alert, and probably more alerts suddenly went off while driving. Warning Lights for all these features stayed on, and I completely lost regenerative braking and power braking. I'm not sure if I lost anything else because I immediately pulled over, having to stand on the brakes to slowly stop. Once at a stop, I put it in park and warnings about parking brake faults continued to go off. I turned off the car, and warning about a parking brake fault continued to go off. I waited a few seconds and then opened the door to force the normal system shutdown. I pressed the brake and hit the start button again, but it didn't seem to recognize that I had pressed the brake and started in accessory (ACC) mode. After a few more second, I pressed the brake again and hit the start button (while still in ACC Mode), and the vehicle moved to full running mode without all of the warnings. This situation could have easily resulted in a full crash if I were driving at a faster speed and/or if I required immediate stopping.
