“I was driving down the street and suddenly lost all motive Power, vehicle became difficult to control. I have a video. The car also made a grinding feeling and very loud whining noise”

NHTSA complaint #11682571, filed 2025-08

“While driving on a public road, the vehicle suddenly shut down and rebooted itself. Motive power was lost during the event. This has happened at least a dozen times during normal driving, including while transporting a child. Video of an occurrence was recorded. The vehicle is a 2025 GMC Hummer EV with approximately 10,400 miles and has been in service about eight months. This creates a serious safety risk. A sudden loss of propulsion and system reboot while moving can leave the driver unable to maintain speed or control in traffic and increases the risk of a crash. …”
