2017 GMC Sierra 1500: brake failure

Filed Jul 10, 2025 · Brakes · WI

My 2017 GMC Sierra Brakes started acting up a slow speed it would seem like there were no Brakes or Pedal would push very hard. I pulled into a parking space at the store and it was like I had no Brakes had to push pedal very hard and Thank god there wasn’t a car in front of me because I would have hit it. The truck has new front and back Brakes and Rotors put. The truck was throwing some codes and 3 out of the 4 codes pointed to faulty Vacume pump. I pull a camper and sometimes a side x side so this is very concerning and I hoping to get this expense covered by Recall like all the other Models with the same issues. I really don’t know why my truck isn’t being Recalled. This has been a good truck for me no complaints tell this.

At low speeds I have no brakes.

The incident occurred on [XXX]. My vehicle has 54,571 miles on it. The power brake assist function failed. I was backing into a parking space at a local fast food chain and experienced near brake failure. I had to stand, nearly full body weight pressure, on the brake pedal to get my truck to stop at very slow speed. I, again, backed a short distance of a couple of feet at the most and experienced the same issue when I tried to stop. I placed the vehicle in PARK and turned the engine and ignition key off, thinking the system possibly needed to reset. I started the truck and drove forward, very slowly, to another parking space and applied the brakes. I experienced near total brake failure again. I had my truck into Brogden GMC in Olathe, Kansas on [XXX], for general maintenance and a “brake pressure recall.” I had experienced a slight brake pressure issue on a couple of occasions prior to the recall. After the recall service was performed I did not experience a braking concern for some time. I did experience “soft braking” a couple of times after the recall was performed and attributed it worn brakes. On [XXX], at 50,596 miles, I upgraded my brakes by installing a Power Stop Z36 brake kit with slotted rotors and ceramic pads. I have not had a repeated experience of soft braking or brake failure until the [XXX] incident that I am currently reporting. It appears to me that the earlier recall did not completely address the brake failure issue with my 2017 GMC Sierra 1500 pick-up.

The service message appeared on the display after backing up "SERVICE BRAKE ASSIST" I searched this issue and found over 65 complaints for this vehicle year/make /model. I am at work and fear driving home as this issue has resulted in brake failure on some of the complaints noted. I have not contacted anyone yet, I wanted a recall notice as this is a safety issue and we cannot afford any costly vehicle repairs.

The trailer brake system on my vehicle suddenly stopped working. I was alerted by a continuous chime and message saying "Service Trailer Brake System." My brakes stopped working and made it difficult for me to stop my vehicle and loaded trailer. It was very frightening because I had lost all trailer braking function and feared I would not be able to stop my vehicle. In addition, the chime and message are non stop and very distracting and cause some components of my dashboard to be inaccessible making things more dangerous. Unfortunately, the distracting and frustrating chime and message continue even without a trailer attached.

Leaving a parking lot and had a complete loss of brakes due to faulty vacuum pump.

Filed Nov 29, 2021 · Brakes · SD

While in a parking lot, I tried to slowly move forward and then come to a pause. My brakes didn't work quite right and the vehicle didn't stop for an additional 15-20 feet from where I would have liked to stop. Luckily I was just moving forward to get out of the way of another vehicle trying to drive behind me and I didn't have anything directly in front of me that I needed to stop before. If I was trying to stop for a pedestrian I would have certainly hit them. If I was trying to stop behind a vehicle who suddenly stopped I would have ran into the back of their vehicle. There has been a recall on similar vehicles; same make, model and year as mine for what appears to be the same issue. Recall # 19V645000 This has also happened in my garage while pulling in, and in another parking situation. The Service Brake Assist warning comes on the Information screen.

Low speed braking issue. Was in a parking lot trying to park moving about 1 or 2 MPH. Truck would not stop and it was like there where no brakes until I pressed as hard as I could. Does not do this at normal speeds

Our truck is less than three years old with approximately 69000 miles. The transmission just started slipping out of the blue while driving thru a neighborhood. While in drive it would move but once accelerating it would rev up and not change gears. This happened without warning, without an engine or warning light. We do all the necessary regular maintenance. In addition two years ago while the truck was a year old, the brakes went out while driving on the interstate. I guess it was the brake vacuum pump or whatever that didn't allow the brake peddle to be pressed which provided me with no brakes. Again with absolutely no warning! This later became recall issue but not before it had already happened to me! I understand there is a class action law suit against gmc for transmission problems and I would consider being a part of this. This is a 50;000$ and relatively new truck, this is unacceptable! The dealer now wants over 4000$ for repairs.

Tl* the contact owns a 2017 gmc sierra 1500. While driving approximately 20 MPH, the brake pedal was depressed and traveled to the floorboard. The brakes failed to adequately slow down the vehicle. Prior to the failure, the vehicle was taken to mastria buick gmc (1525 new state hwy, raynham, ma 02767, (508) 880-7000) to be repaired per the federal safety agency campaign number: 19v645000 (service brakes, hydraulic). The contact stated that the failure recurred twice after the repair. The manufacturer was not notified of the failures. The approximate failure mileage was 40,000. *bf

Total brake failure. The pedal became hard as a rock with no advance warning. I received a notice (n182202780) from gm stating that I might experience increased brake pedal effort. It went on to say how this notice "is not a reacall" and that brakes still meets "all federal motor vehicle safety standards for brake performance" I'm writing to bring attention to the fact that my truck experienced no symptoms of a problem until the pedal had maybe 10% assist. No check engine light or notice from the drivers info center. I applied the brake, shifted into drive, accelerated then applied the brake to stop and maybe had 10% braking ability. The notice also went on to say that "failure to follow recommended oil change intervals could contribute to this condition". The truck has 32000 miles on it, I've owned it since new, I have always changes oil with 20% life left in it. This is about 2000 mile sooner than the manufacturer recommends. This is a very serious condition that gm has recognized in there letter, but in my opinion, are not taking it serious enough. Unless I'm a "one off" case, this will very likely get people hurt and property damage if not addressed very soon. Please look into this, thank you

I had the rotors replaced on my new truck at 6000 miles and paid for repairs out of pocket. I continued to hear brake noise. On my way to the dealership on the weekend I was scheduled to have the brake noise investigated and to have an oil change done, I had catastrophic brake failure. A vehicle in front of me made a lane change into my lane and then slammed on the brakes in front of my vehicle at a green light coming to a complete stop from 40 MPH to 0 in the middle of the intersection. A car had pulled out in front of him changing lanes from the left lane to right. I mashed the brake pedal to stop immediately and my brakes went soft and to the floor on the second push. When I wasn't stopping. I slammed my emergency brake with my left foot and injured a few toes on my left foot trying to stop before my vehicle. My vehicle did not come to a complete stop. Instead, my vehicle skidded and lightly tapped the vehicle in front of me doing minor bumper damage to both of our vehicles. However there was a toyota truck behind me, and struck my vehicle directly while I was at a stand still, while the driver was doing over 70 MPH when he collided with my sierra. My sierra has the pin or part of the caliper that moves the brake pads, completely pushed the piston into the rotor. The vehicle has had brake issues since I paid to have the brakes and rotors replaced at 6000 miles. I have records of the incident and the brake failure from a mechanic and auto body shop documenting the complete failure of the brakes. Directly after the brakes were replaced within another 8000 miles the brake booster on the vehicle went bad and was replaced as well.
