Car Will Not Start problems of the 2017 Chevrolet Traverse

While driving my 2017 Chevrolet Traverse at interstate speeds, the vehicle, without warning, shut down. When I say shut down, I mean shut off completely. This was a complete loss of all power to the car. The engine shut off, the lights (internal and external) shut off, there was no power steering, the brakes where difficult to push down, etc. As I am now coasting down the interstate with no power to the car I put it in neutral and turned on my flashers. With no power steering and brakes that are stiff, I somehow was able to slowly force the car to the side of the interstate and get it to stop. I tried to restart the vehicle and it would not start. I put it in park and sat there for a few minutes before trying again. Once I tried, the vehicle started and I was able to drive home without further incident. The morning after this incident, I started up my Traverse and noticed that the fuel gauge is showing empty, but the car had a half of a tank when I got home last night. There is something serious going on with this Traverse and Chevrolet vehicles in general. This is the 2nd different vehicle that I have owned that has shut down while driving down the road. The 1st car was a 2016 Chevrolet impala.
