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. Multiple attempts were made to move the vehicle, it was blocking a flow of truck traffic at the business. No movement occurred. OnStar was contacted for road side assistance and a Wrecker…
I am reporting a safety defect involving my 2025 GMC Hummer EV 3X (VIN: [XXX]). On XXX at approximately 18,880 miles, I first presented the vehicle for steering/alignment, suspension, and handling concerns. As of this complaint, the vehicle has approximately 26,840 miles. I have driven nearly 8,000 miles while repeatedly reporting unresolved safety concerns and transporting my two children (ages [XXX] and [XXX]) because I had no practical transportation alternative. Following warranty repairs, including rear control arm replacement, the vehicle developed a severe pull to the right that did not exist before repair. It requires constant steering correction to remain in its lane, and Super Cr…
Under full acceleration on flat, dry pavement, the vehicle suddenly pulls hard to the right or left without any steering input. The steering wheel does not move, but the vehicle abruptly changes direction, requiring immediate counterâsteering to avoid losing control. This happens every time under full acceleration and has been confirmed by two GMC dealers. GM Corporate states this is ânormal,â but the behavior is unsafe and could cause a crash. Two GMC dealers reproduced the issue and confirmed the sudden directional pull under full acceleration, but both stated it is ânormal.â GM Corporate also acknowledged the behavior but claims it is within manufacturing tolerance. The vehicle…
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 vehicleâs 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: âService…
Charge port door on vehicle will not open regardless of what you do.
The frunk latch on the vehicle becomes faulty and does not recognize the hood being latched and secure when it is. While driving, the vehicle without warning will immediately limit speed to 26mph regardless of existing vehicle speed. This has occurred multiple times when driving on the highway with the vehicle immediately decelerating and then saying the hood (frunk) is open. This poses a serious danger to not only the occupants of the vehicle but also those around them on the highway. This occurred when traveling at highway speed in the middle lane. This resulted in the inability to change lanes to pull off the highway due to the drastic reduction in speed in reference to the other vehicles…

No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
