On Oct 11,2026, at approximately 105,106 miles, I was driving my 2023 GMC Sierra 1500 under 20 mph while entering a short designated turning lane at [location]. I felt a sudden, unexpected bump or jolt. The truck slid slightly and abruptly came to a complete stop, as though something had mechanically locked up. Immediately afterward, the dashboard displayed a “Braking System Failure” warning. A front wheel appeared collapsed underneath the truck, with substantial visible damage to the front suspension and surrounding components. The specific component that failed first and the initiating cause are UNKNOWN. I did not knowingly strike a curb, pothole, road debris, another vehicle, or another object before the incident. The truck has no aftermarket lift or leveling kit. I purchased it less than two weeks before this occurred. The wheel collapse, sliding, and sudden stop compromised my ability to safely control the truck and created a risk of collision with surrounding traffic. A similar event at higher speeds could have caused a serious crash. The truck is being towed to the selling dealership, which is covering the towing cost. I am seeking an independent GMC inspection and requesting preservation of damaged components and diagnostic data. Inspection availability can be coordinated with me and the dealership. At the time of this report, I have not received a confirmed mechanical diagnosis. Inspection by the manufacturer, police, insurance representatives, or other parties: [state who has inspected it, or UNKNOWN]. The braking warning appeared immediately after the sudden stop. Earlier warning lights, messages, or symptoms: [describe any, state NONE if accurate, or UNKNOWN]. Photographs are available. I can provide inspection findings when available.

My 2023 GNC Sierra 1500 has experienced a recurring electrical and safety-related malfunction on multiple occasions while driving. The dashboard and warning lights intermittently flash on, and off and numerous warning messages appear simultaneously. During previous occurrences, warnings included power steering service, safety restraint system, check engine and transmission related messages, including a message instructing me to pull over and shut the vehicle off. During one occurrence, the electric power steering assist stopped working while I was driving. The vehicle was taken to an authorized GMC dealership multiple times while under the factory warranty. The dealer replaced the Brake System Control Module and performed vehicle-wide software/programming updates. When the problem continued, the dealer contacted GM Technical Assistance. The Dealer subsequently diagnosed an intermittent open circuit involving the electric power steering rack-and-pinion/steering gear assembly and replaced the complete steering gear assembly. Despite these repairs, the malfunction has occurred again, during another occurrence while driving on the freeway, the dashboard flashed on and off and multiple warning lights and messages repeatedly appeared, similar to the condition that occurred before the steering gear was replaced. The vehicle currently has approximately 55,000 miles. The condition remains intermittent despite multiple repair attempts. I am concerned that this recuring electrical or vehicle communication failure could again cause loss of power steering assistance or affect other safety-related vehicle systems while driving.

The vehicle has suffered repeated systemic electrical failures all while being under 8,000 miles. What component/system failed? Power distribution/fuse block, starter, fuel pump control module, horn circuit, body control module, instrument cluster, and charging system. Error codes documented include P0627 (Fuel Pump Control Circuit), U0100 (Lost Comm ECM/PCM), B1325 (Control Module Power Low), U0140 (Lost Comm BCM), and B1000 (ECM fault). All repairs are documented by the dealer, and the truck remains available for inspection. How was safety at risk? The truck lost propulsion at speed, emitted smoke from the engine bay, and became disabled in traffic, placing my family, including my toddler, in immediate danger of collision and fire. Electrical defects also disabled horn and instrument cluster, removing critical warning and signaling functions. These electrical issues have been ongoing for months and GM refuses to replace and can't seem to fix it. Has it been confirmed? Yes. Each failure was diagnosed and confirmed by an authorized GM dealer. Components replaced include fuse block, starter, fuel system computer, horn assembly, and cluster. Despite repairs, issues recur. Inspected by others? GM corporate case managers are aware and have acknowledged defects, though they have refused to issue written determinations. Insurance has not yet been involved, but records are available. The dealer has attempted to repaid more than 4 times with no success. Warning lamps/messages? Yes. Prior to and during failures, vehicle displayed repeated “Service Electrical System,” “Low Voltage,” and communication fault codes. Cluster intermittently blacked out. Smoke in engine bay indicated immediate fire hazard. Cumulative out-of-service days exceeding 20. The failures pose unacceptable risk of fire, sudden propulsion loss, and loss of critical safety functions. I have ALL calls with GM recorded and transcribed as I am in SC (single party recording state) and can provide those.

I just left the gas station from getting a beverage, I got onto the interstate and had gone roughly about 3 miles before setting super cruise a few minutes after that the interstate takes a turn to the left with an exit on the right. Slightly right as I was just getting into the turn my engine shutoff and or died making my truck uncontrollable causing me to drive off the interstate into some small trees between the exit and the interstate. I was not injured and no other vehicles were involved. My truck is currently at the insurances storage yard and they care claiming it to be totaled. I have contacted GM and filled a claim however they are saying they aren’t responsible because the insurance company has my truck. I feel like regardless of who has my vehicle the manufacturer should be responsible if the issue pertains to a specific recall that has already been issued 2 weeks after my accident. I have contacted several lawyers but since I wasn’t injured they aren’t interested in taking my case. My concern is I’m getting screwed over financially because my truck was only a year old and now my insurance is going to be crazy expensive when the manufacturer should be the one taking responsibility for this and not myself.

Subject: Safety Complaint Regarding Steering Airbag Trim and Steering Axle Issues (the federal safety agency), I am writing to formally file a complaint regarding serious safety issues with my GMC vehicle. Specifically: 1.The steering airbag trim has begun to crack, which raises concerns about its structural integrity and potential interference with airbag deployment in the event of a collision. 2.The steering axle is making unusual noises due to loose bolts and worn bushings, posing a potential risk to steering control and overall vehicle safety. I recently took the vehicle to an authorized GMC dealership for inspection and repair. However, the dealership refused to address these issues despite their clear impact on safety and their apparent connection to manufacturing defects. Given the critical nature of these problems, I urge the federal safety agency to investigate this matter thoroughly. These defects not only compromise the safety of the vehicle but also endanger the lives of the driver, passengers, and others on the road. Thank you for your attention to this matter. I am happy to provide any additional information or documentation required for your investigation.
