On 10/03/21 at approximately 1251 hours, I was driving my 2018 Chevrolet silverado which is the vehicle with the above mentioned VIN. As I was traveling towards a heavily traveled intersection in my current city, I approached a steady red signal on the traffic light. It should be noted that this particular part of the roadway is a slight decline towards the intersection and traffic control signal. It should also be noted that on this particular day, there were no inclement weather or roadway conditions that would affect the vehicle to deviate from normal maneuvering. As I applied the brakes at a reasonable distance from the stop light, almost all pressure and power towards braking was lost. As a result, I was forced to apply extensive pressure to the brake pedal as the vehicle failed to slow and stop in a timely fashion. After gaining some braking power, the vehicle and brakes began to shake and produce a clunking sound. This was troublesome because had I failed to stop in a timely manner, I or other motorists could have suffered serious injury or death as a result of a crash at a heavily traveled intersection. Prior to this incident, there were no warnings or alerts provided by the vehicle, dealer, or manufacturer about this issue. As the event occurred, an alert flashed on my dashboard that read “service brake assist. ” following the incident, my vehicle was inspected by a certified mechanic. Said mechanic deemed that the problem with the braking was a result of a failure of the brake booster vacuum system. After doing some research, it is apparent that other years, makes, and models of GMC products suffered the same issue with the braking system. Said issues were remediated with a recall by the manufacturer. This defect also caused numerous vehicle crashes with reported injuries.

I was given a 2019 chevy silverado and when I turned the truck off the shift to park light would stay on and in February the brakes froze with the bad freeze when it thawed the brakes just started locking up by them selves I could not get over 5-6 mph so I made an app with dealership took it in told them what it was doing they had it a week they replaced shifter handle and bolt and reset codes I get the truck back did not have it 24 hrs I was leaving where I was fishing that morning I was going maybe 40 mph when the abs and other lights came on on dash and the brakes locked up again sending me sliding about 60 yards when I ended up in a ditch I tried to get out and the truck would not move so I get out and look to see my front passenger tire completely broke off folding up under truck. No one else was involved I automatically called dealership told them what happen filed a crash report and tow truck took truck back to dealership I contacted gm snd they sent an investigator to look at it but denied my claim said it was not a manufactur defect. . So no one is wanting to fix my truck now it’s still under warranty with less than 19000 miles on it. . . And if I was to pay out my pocket to fix it I feel that it will happen again cause the freeze did something to the electrical brake system. . The truck is a year and 4 mts old. Paid cash for it and not I can’t even drive it. .

Abs (trailer braking system) and stabitrak warning lights randomly come on while driving and remain on until vehicle turns off. On multiple occasions the rear wheels have locked and steering becomes difficult even when brakes are not being applied. This has occurred while driving at varying speeds and in varying weather conditions. Vehicle has been checked by dealer on 3 separate occasions for this and service was reported unable once lights have gone off. Said incident has occurred approximately 30-50 times over the past 18months.

In may I purchases a 2020 silverado. On December 05th, 2020. I was driving on the interstate heading home from my son's football game . The "service brake system" message displayed on the vehicle's dashboard. Braking became sluggish and stiff. I initial thought the brake fluid had had leaked out. The vehicle maintained power to all other systems. Once home I checked the engine bay and brake calibers and found them to be intact. At this time the vehicle has 12,400 miles. After a initial assessment, was informed that it was determined to be a "computer glitch" that was effecting the transmission and brake sensors. The brake module was replaced and transmission "software" was updated. This was completed on December 09th, 2020. Upon completion the techs conducting a "drive test", at which time the warning appeared again. My vehicle remains at the service department, while they "troubleshoot" the problem. Due to the vague responses being provided by the dealership service staff and the lack of an estimated time line for the completion of the repairs. I believe there is a much larger issue that they don't want to reveal.

While driving on 30-40mph and hit the brakes slowly, it feels as if the pedal is gonna fall off and can also feel a vibrate on it. It also stalls as if the brakes are being pressed but I'm not, this happens usually in the beginning after being turned on and then stops doing it after reaching the middle of the temperature.

On 10/26/2019, the 2017 Chevrolet silverado was being driven in heavy traffic on the 134/210 freeway area of glendale, California. The truck was going 10 mph, and when the driver went to stop, the brake petal pressed to the floor, resulting in a rear end collision with the car in front of it. The driver of the first car appeared uninjured, but filed a claim later that he had ongoing lower back issues. The brake light only went on after the incident. The truck was driven to a local Chevrolet dealer and the brakes were serviced a few days later. The vacuum pump was the reason why the truck did not stop. It is notated on paperwork and confirmed when speaking to the service manager on Friday, November 1st at 4:30 pm. The service manager also reported there was now a recall to fix the problem, so it would be fixed and a new vacuum pump would be put in (vacuum pump replacement special coverage n182198000). A claim was filed with GMC to pay for the damage and take over the insurance claim made by the owner of the truck, as well as the car in front of it. GMC came out to the Chevrolet dealer during that time, and GMC reported to the owner that they would not help with fixing the vehicle or the insurance claims. The owner requested the final report three times and there was no response. The truck had been reported to multiple service providers that there were issues with the stopping of the brakes in 2019. It was requested by the owner that the brakes were inspected so that they could be replaced if needed. There was also an incident in July 2019 where front and rear brakes were interchanged on the paperwork and the owner of the truck was told that it was just a paperwork mix up because they "fixed the brakes that were bad. ".
