Charge port door on vehicle will not open regardless of what you do.

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. I was NOT issued a citation. (see report attached) The vehicle has since been towed to Northwest Hills Chevy/GMC in Torrington CT for inspection by the GMC manufacturer. This incident raises serious safety concerns, as the sudden loss of steering control at low speed could have resulted in significantly more severe consequences under different circumstances. I was in a school zone at dismissal time going to pick up my son. This appears to be a potential mechanical or electronic steering system failure. I believe this represents a serious safety defect that should be investigated to prevent similar incidents.

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 on the highway causing a high stress and high risk situation for the driver and occupants.

The vehicle was no longer able to charge, and therefore could be stranded. Yes, the vehicle is currently back at the dealership and available for inspection. Without ability to charge, the vehicle could shutdown and not be able to restart. Yes. It was at the dealer from 6/27 to 8/20 and then the issue re-exhibited on 9/3 and it was returned to the dealership. Yes, it was reviewed by the dealership and returned, only to happen again within 100 miles. Yes, the Service Engine Soon light appears.

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. I do recall that when I was pressing the brake pedal, the vibration felt somewhat similar to vibration of the ABS brake system when the tires are losing traction but the vibration was much more pronounced. I pulled the vehicle onto the side of the road and checked the driver information display. A "Service ESC" notification appeared on the driver information panel followed by "One-Pedal Driving Unavailable Use Brake for Stopping". No other warnings or notifications were observed after this incident and the vehicle seems to be driving normally. I was able to re-enable the one-pedal driving mode the next morning.

The windshield wipers do not work. When the wipers are turned on, the spray comes on and does not turn off. You are unable to see as the spray keeps spraying the entire time the wipers are on. I took the dealer twice and they have been unable to repair. They now say are waiting for parts. I can't be the only one. This is very concerning. Luckily I live in Las Vegas and we have little rain. What component or system failed or malfunctioned, and is it available for inspection upon request? wipers and yes How was your safety or the safety of others put at risk? You literally can't see if you use the wipers. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes been to service twice. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The Dealer only. GM does not seem to care. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning. I turned on wipers when it was raining. Luckily I was close to home. You cant see. Super dangerous.

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 [XXX] . 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.

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. I filed a complaint with the BBB hoping to get the attention of someone who would actually realize how unsafe this is and that same person from GM lied and said I declined assistance. I asked that lady for help and she stated that it would have to wait until something else happened.

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 counter‑steering to avoid losing control. This happens every time under full acceleration and has been confirmed by two GMC dealers. GM Corporate states this is “normal,” 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 ‘normal.’ GM Corporate also acknowledged the behavior but claims it is within manufacturing tolerance. The vehicle still pulls violently to one side under full acceleration, creating a serious safety risk.

The super cruise self driving system is entirely defective and faulty, this is a safety issue.

The contact owns a 2025 GMC Hummer EV. The contact stated while driving at an undisclosed speed, the message "Forward Collision Avoidance System Unavailable" was displayed. The contact stated while another vehicle pulled in front of the contact's vehicle, the forward collision avoidance system and the side-view sensors safety features failed to engage. The vehicle was taken to the dealer, but was not diagnosed due to a schedule error. The diagnostic testing appointment was rescheduled for a later date. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

On [XXX], my [XXX] son was riding in the back seat of our 2025 GMC Hummer EV (VIN: [XXX] ) and reported his seatbelt felt loose. I pulled over and discovered the seatbelt bracket was completely detached from the vehicle frame. The bolt was present, but the nut that secures the bracket was entirely missing, leaving the belt nonfunctional and my child at risk of serious injury or death in the event of a collision. This is a catastrophic failure of a federally regulated safety system. I immediately contacted GMC and the dealership, explained the issue, and stated the vehicle was unsafe to drive. Despite this, I was told to drive the vehicle in for service on 6/9. The dealership confirmed the nut was never installed during manufacturing. However, instead of repairing the defect properly using OEM hardware and torque specs, the dealer used a generic lock nut found in their shop and said it “should hold.” No engineer signed off on the repair. There were no warning lights or messages. The issue became apparent only after my son noticed the looseness. The vehicle also has other documented issues: mirror folding failure, seat cushion defect, hydraulic frunk failure, swing gate malfunction (fixed), and a squeaky rear door. All were diagnosed on 2/28/25 and parts were ordered. I received no follow-up. When I returned on 6/9, nothing else was repaired. The advisor said the original technician had left and the new one couldn’t proceed. I also own a second 2025 Hummer EV (VIN: [XXX] ) and am now concerned about its integrity. This experience has caused ongoing emotional distress. GMC’s failure to inspect, respond, or properly repair a critical seatbelt defect demands NHTSA investigation and possible recall.

The contact owns a 2025 GMC Hummer EV. The contact stated that while the vehicle was stationary, the brake pedal was depressed, and several unknown warning lights illuminated. The contact stated that while the vehicle was idling for several minutes, several unknown warning lights illuminated. The vehicle was then taken to a dealer where it was inspected by an engineer who stated that the system was extremely sensitive, and the dealer stated there was no additional assistance that could be provided. The vehicle was not repaired. The contact stated that while driving at an undisclosed speed on another occasion, several unknown warning lights illuminated. The contact was informed the system was extremely sensitive and the issue would reoccur. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 2,300.

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.
