Starting vehicle in parking lot and backing out of parking space. Brakes failed and truck continued to roll backwards almost hitting a pedestrian. I was able to stop hard on the pedal and stop the vehicle. This has happened several times. I have a steep driveway and backing down to the street the brake pedal will unexpectedly have little resistance and the truck will continue to roll into the street almost hitting oncoming traffic.
I was driving pulling an empty small U-Haul trailer and attempted to pull in to a fuel station when my brake became impossible to depress. I barely was able to miss hitting gas pumps and ran down into a ditch before the truck stopped. I informed the dealership where I had just purchased this truck used. I took it to their service department and I was told there was no issues with the brakes. They had to have this recall bulletin in their computer system yet failed to make me aware or to perform this recall or report it to GM. The problem continues to worsen to the point I am scared to drive it. I almost rear ended another car at a stoplight yesterday because I was unable to depress the brake pedal. I stood on the brake and heard an electronic sound but finally came to a stop.
"NHTSA campaign: 19V645000 AS the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash." Our vehicle was serviced and repaired for this problem under the recall on 9/6/2019, however, it is now happening again. Is there a second recall for this problem, and/or what can be done to remedy the defective equipment?

upon applying brake pedal at low speeds the brake is hard to depress and "choppy" in reacting. this seems same as N192268490 Increased Brake Pedal Effort yet the gmc denali is not apparently in the recall. This has happened on several occassions.
The brake system failed in a parking lot three times within a month. It-??s related to the special policy and recall regarding the vacuum and the loss of brakes at slower speeds and in reverse. The first two accidents were very minor creating no damage. The third one was at 10mph when I lost my brakes and crashed into a concrete barrier in a parking structure causing significant damage to my truck. I did not get injured but I have a wife and two kids that I am so grateful were not in the truck for the third one with major damage. With that being said my son was in the truck the second time it happened when I crashed into a parked vehicle in a parking lot because I was unable to stop which made me very frustrated and worried for my families safety in my truck. The first accident was in a parking lot where I was backing up and lost the brakes and crashed into a building which is my veterinary office causing damage to the building. Therefore after the first crash due to this issue I have decided that driving with my family in the truck is not an option anymore. It is very disappointing that a truck I purchased for the functionality and safety of having my wife and kids in it is no longer safe for passengers or myself in it. This problem is very reproducible and is a major concern for my family and my safety. It was towed to a GMC dealership in Waukesha and is being inspected and they have stated it is reproducible. No warning lamps or messages were indicated for this issue. The truck will next need to get towed to Crash Champions auto body repair to ultimately get repaired which will take another month. All of this is a major inconvenience as I am a full time firefighter and in paramedic school as well. Not having a reliable safe vehicle for an extended period of time has caused great stress and inconvenience to my family. I-??m hoping and praying that something can be done about this quickly and promptly to make this right. Thank you.
Intermittently with slow driving such as parking maneuvers or creeping slow traffic at stop lights the brake pedal becomes very soft and depresses much more than normal and the brake action is decreased. Sometimes with this soft pedal it sounds like ABS is engaging. Pumping pedal sometimes restores brake performance.
Rainy road, 60mph on the hw with my family. Truck decides to engage stabilitrak or something to that feel and locked up the brakes. Talk about a scary moment with an 18 wheeler coming in hot behind you. Obviously, in the moment, I had no clue what was happening other than something with the truck was malfunctioning. This scenario could have gone wrong in so many ways. I'm honestly in shock someone has not been killed because of this?
The brake vacuum pump is failing. When in a parking lot the brakes get very hard al.ist causing an accident. There is no vacuum when trying to park in parking lot. The 2015 GMC Sierra had a recall for this but my VIN did not. Not sure why as it's failing too. I need my truck so will have it fixed today, but want a recall.
