A little over a month after purchasing my brand new Hummer EV 2X I was driving and then I lost all power, brakes, steering, and had to coas t to a stop. My rear motor blew and snapped my trans axle. I had only 2,000 miles on the odo. This vehicle is riddled with issues that limit its ability to use safely.
