2025 Chevrolet Silverado 1500 driver assistance problems

Filed Sep 30, 2026 · Acceleration, Driver assistance · CO · crash

On XXX at ~3:00 p.m., I was driving my 2025 Chevrolet Silverado 1500 High Country (VIN [XXX]) in stop-and-go highway traffic with Super Cruise engaged. The vehicle ahead was a truck towing a low, empty flatbed trailer. My truck came to a complete stop behind the trailer. While stopped, with no accelerator input from me, the vehicle accelerated forward on its own and struck the rear of the flatbed before I could intervene. My foot was not on the accelerator. It appears the forward sensors may not have detected the low, unloaded trailer as an obstacle, so when the system resumed from the stop it accelerated into it. No injuries. The other vehicle had a steel rear plate and was undamaged; damage to my truck is estimated at $3,549.68. A vehicle that accelerates on its own from a complete stop into a stationary object ahead is a serious hazard. This was low-speed property damage only, but the same failure at higher speed, or with a pedestrian, cyclist, or child ahead, could cause death. I have an infant, and the thought of this happening with my child aboard is alarming. I am concerned that low-profile or unloaded trailers may not be reliably detected by the forward sensing system — a systemic limitation, not a one-time glitch. I ask the federal safety agency to review whether other GM/Super Cruise vehicles have experienced unintended acceleration from a stop or failure to detect low trailers. I notified GM (Chevrolet claim #XXX) and requested the vehicle's Event Data Recorder and Super Cruise/OnStar telematics be preserved. I am filing this so there is an independent safety record.

The specific cause has not been identified. On XXX6, my 2025 Chevrolet Silverado 1500 Custom LT Trail Boss unexpectedly rolled away while parked and unoccupied, striking another parked vehicle. The truck remains at Modern Chevrolet and is available for inspection. GM/ESIS opened a safety and product liability investigation and is arranging inspection/data retrieval. I parked at Walmart in [XXX], shut the truck off, exited, locked it, and walked away. Shortly afterward, I heard a sound resembling the key-fob-left-inside warning. My key fob was in my pocket, so I returned and saw the truck moving with no driver. Another person and I tried to stop it. I entered through the driver’s door and pressed Start/Stop several times, but it would not start while moving. It continued moving and struck another parked vehicle. Vehicle dropped off on XXX and Modern Chevrolet could not reproduce the incident or identify the cause. The service advisor stated it “came out of gear but don’t know why” and escalated it to GM. GM/ESIS plans to retrieve SDM/airbag data, and I requested any Tech II/MDI scan data. No warning lights, messages, or chimes were observed during the incident. I did not see/hear “SHIFT TO PARK,” and I was able to lock the truck with the key fob outside. In a later controlled test, I left the truck in Drive and shut it off. It displayed “SHIFT TO PARK” and sounded a warning chime. Opening the driver’s door also produced a key-fob-left-inside-type alert, which did not occur on XXX. The truck did not automatically shift to Park or engage the electronic parking brake and slight movement was felt during the test. No further testing occurred by me after XXX. I have also experienced infotainment freezing after software updates and random electronic parking brake application when shutting off, and remains engaged after restart. The truck received an oil change/tire rotation at Modern Chevrolet on XXX. Cause still remains UNKNOWN. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving on the freeway and got a service trailer brake system and a brake system failure 62mph top speed. I exited the freeway and came to a stop sign and hit my brakes to stop but was unable to stop and blew through the stop sign. Luckily there were no cars at the intersection and I was by myself.

All sound goes out on this truck intermittently. Maybe once every 3-4 days. I will have 0 sound, the safety feature sounds, the parking assistance, the directional signal sounds, the stereo. It is not Bluetooth or anything interfering I’ve shut my phone off to test. This happens with MANY people. Most people complain online about the stereo and directional sounds being completely muted, but forget to mention or don’t notice that the parking and collision assistance sounds are out as well. It took me a while to realize. I have video of it happening as well

On 3/30/2026, I was driving down the road & suddenly my dash filled with warning lights about brakes, abs etc. Steering the vehicle became almost impossible because power steering was gone. When I attempted to brake, I also found that I had very little braking. The vehicle has 11,036 miles. Got the vehicle to the dealership - Capital Chevrolet from which it was purchased. It has been diagnosed as a major brake failure. Master Cylinder, booster, reservoir, seals etc. Extremely dangerous situation without any early warning signs, lights or notices.

My vehicle frequently loses all cabin sound, including the radio, audible turn signal, and forward/rear collision and lane departure warnings. When this occurs, the cabin is completely silent. The loss of radio audio is an inconvenience, but the loss of safety feature alerts is a clear hazard. My dealership has suggested this may be related to a recent software update; however, there is no apparent correlation between the updates and when the issue occurs.

I have taken my vehicle to the dealership, Preston, Hood Chevrolet, Fort Walton Beach, Florida. The problem I’m having is the avoidance system! Not getting warning nor will the vehicle stop an emergency situation where I’m going forward in a vehicle stops quickly in front of me nor will it work if a person is walking behind my vehicle or if there’s a vehicle behind my vehicle when I’m backing out of my driveway. They keep telling me everything checks out on the computer and they keep saying it’s normal and it’s only meant to possibly slow down the vehicle before a crash. They do not give me any definitive answer and they also escalated to GM response is basically the same thing. You can read all over the Internet that a lot of people have this problems. I have friends that own the same truck and it works perfectly. My truck will not. It’s very frustrating because one of the reasons why I bought a new vehicle like this was for those safety reasons. Also, when I am pulling out of a parking spot and turning the wheel, the truck accelerates by itself and goes into cruise control. Only doing a few miles per hour. And this might be because of the location of the activation of the cruise control switch. It is a lever on the steering wheel and it’s easily to engage. And I don’t understand why it would engage at such a slow speed. I’ve had several situations where a vehicle has stopped suddenly in front of me and my truck will not respond at all with a late morning shaking of the seats no alarm and no breaking luckily I was able to stop in time with my own reaction. The technicians will not work on this because the computer says it’s OK. It seems like they have technicians but not mechanics. My opinion. I spent a lot of money for this truck and I’m [XXX] although my reactions are still pretty good. I’m looking at a vehicle that will assist if I do not react. This vehicle doesn’t react and I paid for this and I am afraid when I need the avoidance system, it won’t work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

While driving to work on [XXX] in Huntsville AL at approximately 55MPH. I was using Chevrolet SuperCruise. I tried turning off super cruise with the super cruise button. It did not turn off, tried pressing cruise control button, nothing, tried the cancel button, nothing, pressed brakes and would not turn off. Truck started slowing in very heavy traffic, it turned hazards on. I was finally able to get it turned off. I have reported to dealer, no surprise they didn't answer, left message at 9 am this morning, no call back. I have made a report to GM. I no longer feel safe putting my family in this truck. This truck has been in shop several times for "Service driver assist", no on-star, no cellular data, extremely slow infotainment system and no supercruise available. The truck at last visit for the service driver assist took more than 2 week. I was told a camera and a software update were performed. The issues have persisted. The super cruise event yesterday was the first occurrence of this type. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
