What 2024 GMC Hummer EV Suv owners say
Electrical system
While operating my 2024 GMC Hummer EV at a low speed in a school zone, I came to a complete stop at a stop sign and began making a left turn. As I initiated the turn, the steering wheel suddenly locked and became unresponsive. I was unable to turn the wheel back to the right or regain control of the vehicle's direction. At the same time, the vehicle did not respond as expected when attempting to stop. Because I could not steer or properly control the vehicle, I collided with another vehicle. The impact with the other vehicle is what ultimately brought my vehicle to a stop. During the incident, multiple warning messages appeared on the dashboard, including a message indicating: "Service Steering System." My vehicle sustained minimal damage due to its height (a bent side step), however the other vehicle sustained damage. Police responded to the scene and a report was filed. …
Super cruise does not work. It may turn on at random for a minute or 2 and then it shuts off with zero warning and the vehicle almost comes to a complete stop. This is a huge safety concern. I took it to the dealership and they told me that this falls on GM 100% as they are being told GMs engineers are trying to find a fix but for now there is nothing they can do, I am to continue driving it knowing this is unsafe. The turn signals and Bluetooth stopped functioning for no reason which had to be fixed Battery charging module burned up at 300 miles. I asked for a buy back and GM refused. I asked for an engineer to come on site and they refused to set it up unless something else is happening as if this super cruise issue isn't enough. …

On August 11, 2025, at about 2:52pm, my vehicle was at a complete stop at an intersection awaiting the traffic light to turn green. There was a slight downgrade slope towards the intersection. The vehicle one-pedal driving was enabled. Weather was sunny with no wind or rain. Suddenly, the vehicle started vibrating violently and started rolling into the intersection. I pressed on the brake pedal but the vehicle continued to vibrate and the vehicle rolled into the middle of the adjoining lane of traffic. There was no traffic on the roadway and no other vehicles were affected. My vehicle had come to a compete stop in the roadway and I attempted to accelerate through the intersection but the vehicle would not move. I recycled the power to the vehicle and placed the vehicle into drive and proceeded to drive through the intersection. …

This is vehicle number two. Also, please take me very seriously as I was driving the vehicle shuts off and says reduce acceleration. I drive a lot from West Bloomfield Michigan to downtown Detroit. I am having so many issues with my brand new GM vehicles please I need help. Please have somebody call me [redacted] . I love my vehicles as I am a repeat customer for years and years, but this is totally unacceptable especially that I have my kids in the car with me.
