While driving around 65 MPH on a highway. The battery light went on. Then suddenly the power steering and brakes died. It was very scary. A hugh safety issue, this very easily could have lead to a serious accident, crash or death. The steering was very difficult to turn and the brakes hard to push down. But the car was still running and luckily I was close to a exit. I pulled off the highway and stopped in store parking lot. It would not start after getting there.
