2025 Chevrolet Silverado 1500

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)
