While exiting highway I attempted to come to stop and my brake pedal was extremely stiff and I had to put hard pressure into brake to come to a complete stop before rear ending the vehicle in front of me. Luckily, I was able to stop before a collision occurred. I was able to get to my destination on city streets, but my brake pedal remained extremely stiff. I was very close to causing multiple accidents due to this brake issue.

Page 3 of 6: complaints 41 to 70 of 144, newest first, as owners wrote them.
Hard braking required to stop vehicle at low speeds. No braking at low speed.
Brake system will turn hard once pressed on. Abs system
Tl* the contact owns a 2014 gmc sierra 1500. The contact stated that while attempting to park the vehicle, the brake pedal was depressed but failed to stop the vehicle. The contact stated no warning light was illuminated. The contact stated that he pumped the brakes until the vehicle stopped. The contact drove to his residence. The vehicle was taken to fairground auto plaza (100 fairgrounds rd, rolla, mo 65401, (573) 364-1002) where the contact was informed that the VIN was included in the federal safety agency campaign number: 19v645000 (service brakes, hydraulic). The recall repair was completed however, the failure recurred intermittently. The contact stated the vehicle was not diagnosed nor repaired. The manufacturer was informed of the failure. The failure mileage was approximately 121,000.
At slow speeds brake pedal is hard to push and does not stop the vehicle. Almost caused multiple accidents at intersections not being able to stop vehicle from going out into traffic. Doing research this has happened on multiple gm vehicles from 2014.
My vehicle brakes become spongy or pedal goes all the way in and vehicle will struggle to stop at low speeds. Such as when I pull into a parking space or backing up.
Excessive hard brake pedal when driving at lower speed, almost got in accident while in traffic due to truck pedal getting hard and truck would not brake. It only happens al low speed or driving in parkinglots.
At low speed stopping I have no breaks, backing up down a boat ramp with a boat I have no brakes. I had the the ABS module and pump changed out and still have the same problem.
Some time traveling between 60-70 MPH the truck has a vibration or something, but if I tap the break pedal it stops. I've had this four times on the interstate. Took truck to the dealer, they found no code listed. Just this weekend as I was exiting the interstate ramp to I-71 south the truck was slowing down and I had pull off the interstate. It was as if the braking system was being applied, truck would not move . Break pedal was very hard to press. I turned the truck off for a couple of minutes and restarted, pedal was still very firm but after pumping pedal, I heard this sound like you were passing gss yourself and then the petal was back to normal. I was lucky that this did not cause a wreck as my speed was being reduced to a slow speed having to pull on interstate.
The brake pedals becomes very stiff at low speeds and does not brake properly. I rear ended a vehicle at 15 miles an hour because the truck did not stop.
This issue relates with a recent recall with the gm brake system (the federal safety agency campaign number: 19v645000 / gm recall number: n192268490). The recall fix by gm fails to fully fix the problem as additional repairs are required to make the vehicle safe again. The incident began when going down a hill at low speed. A message came on the dash that said "service brake assist" and the brakes seemed to lose power which required the driver the use both feet to push down on the brake pedal to prevent a crash into the car in front. The brakes regained normal function for a while then a few miles later the same problem occurred. This went on for for a while longer until the need to use both feet to achieve full stopping power was permanent. Driver pulled over and, through an internet search, discovered many others had the same problem and a recall had been issued. An appointment was made with a local gm dealer and the vehicle was dropped off for repair. The gm dealer called the driver and informed him that additional repairs, beyond the recall instructions, were required for the vehicle's brakes to function adequately and safely. This included replacing the booster pump, brake pads, to "reline the frt brakes as needed."
Intermittent stalling, ( complete shut down at freeway speeds). No engine, no power steering or brakes, windows will not operate, no emergency flashers, no dash re-out, will not turn over. Happens at any time while in motion. Has placed myself, my wife & other drivers in danger numerous times.
Tl* the contact owns a 2014 gmc sierra 1500. While driving approximately 50 MPH during inclement weather, the vehicle suddenly veered to the left and crossed over a lane. The vehicle spun 180 degrees and crashed into a ditch. The rear passenger wheel dislodged from the vehicle and was located approximately 150 yards from the crash sight. The air bag did not deploy and the driver sustained a bruised neck. Medical attention was not received. Police report number: spc32b7n80x was filed at the scene. The contact discovered that a 10-inch section of the brake rotor was missing from the vehicle. The vehicle was recently serviced for the federal safety agency campaign number: 19v645000 (service brakes). The manufacturer and hudson gmc (2023 south rd, poughkeepsie, ny) were notified of the failure. The failure mileage was 72,000.
Took it to the dealer for the recall on the ABS breaks, and now it is doing exactly the same thing that it was recalled for. The recall was not helpful.

Tl* the contact owns a 2014 gmc sierra 1500. While depressing the brake pedal to stop the vehicle, the pedal was very difficult to depress and the stopping distance increased. The vehicle was taken to abeloss gmc (1169 north 9th st, strougsburg pa, 18360) where it was diagnosed that the brake booster was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 80,000.
I came up to an intersection, pressed my brakes, and they were hard to press causing me to run the red light and almost hit another vehicle. Even if a part fails, this should not be an outcome. Brake petal so hard you can't get the vehicle stopped.
Breaks do not work at low speed in reverse, break pedal goes all the way to the floor and excessive pressure must be applied in order to stop vehicle, this is extremely unsafe due to low visibility when backing the vehicle.
Brakes suddenly lock and the peddle to break gets really stiff that when im trying to brake it does not work... I have had this issue happen to me twice already , I was able to avoid an accident because I used the emergency brake,, I was out of town and when I was arriving to the hotel my brake peddle locked and could not brake the parking concrete stopper prevented me from hitting thr building , I noticed that when I shut off tht truck and turn it back on thry work normal again and I am able to brake just fine this happens randomly , I can be on my normal routine for a month then all of a sudden the brake peddle gets stuck,, it looks like its a software glitch like the stability track turning on when its not supposed to , other people are having these issues with these trucks, please investigate..
Braking at short distances. Vehicle continues to move after brake is depressed.
When truck is put in reverse, all power brakes are lost. Assumption is a fault vacuum pump
At slow speeds and brake pedal requires immense force (~200lbs) to press and engage brakes. Significant grinding can be felt in the pedal. This often requires emergency brake usage to stop. Condition is intermittent. Occasionally happens in reverse occasionally forward with wheel turned or without.
While backing slowly on a boat launch ramp, petal was depressed all the way and the tow vehicle did not stop immediately. Felt as though the petal was to the floor, vehicle rolled up to several feet before stopping. Towing roughly 6800 lb. Which is within specification limit for this specific vehicle.
Brake pedal randomly requires significantly higher pressure to slow/stop the vehicle, particularly at slow speeds. Has happened 2-3 times over the past year and this week is occurring more frequently; even daily.
Loss of brakes at low speed, forward and reverse. Brake pedal gets stiff and brakes barely stop the truck.
All happened same day. Was 8 hours from home and pulling into parking spot and the brakes went to the floor 3 times. Has not occurred since. But when that happened the air started blowing warm and the service driver assist came on briefly. Still air is blowing warm and the service driver assist comes on. Have never had a check engine light come on. I am having it checked out this week.
Two different times being at low speed almost a roll. Went to apply brakes and truck barley stopped. Hard brake pedal, brake pedal to the floor. Once on a highway in extreme heavy traffic on a down hill. Second time rolling making a turn to park in a parking lot and almost struck police car and a gas pump.
At low speeds braking is very hard can barely push in the brakes. Sometimes I have to use the emergency brake. Truck has 69,000 miles. At the brake place they said I had a bad vacuum for the brakes and is very common in this truck
The vacuum assist pump on my 2014 gmc sierra went out suddenly during my morning commute. The brake pedal became very firm and the brakes were unresponsive. If I had been driving in an congested area an accident would likely occur.
