2025: “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.”
NHTSA complaint #11652236, filed 2025-042024: “During the morning drive, while in one pedal driving mode, the need to apply more brake due to a quick change of traffic lights occurred. The brakes felt hard and the vehicle did not feel like it was stopping as quickly as it normally would. When I parked the vehicle and exited no warning lights or other items were shown on the dash. Once I got back in the vehicle, a MIL light was lit and the Service Brake Assist message was displayed. With the vehicle running, it would not move either forward or reverse. …”
