Unable to brake at low speed idle. Brakes occasionally lose power when at low speed, for example stop and go in line at a restaurant drive through, or behind a line of cars at a stop sign. Brakes become hard, maybe 1/4 -?? pedal travel and very difficult to stop and avoid collision with car in front. No issue at higher speeds.

At low speeds, the braking system is not operating at 100% efficiency. The pedal must be pushed hard and the vehicle does not STOP promptly. Happens in forward and reverse. There is also a grinding sound when this happens.

When driving home from work one day driving at low speed (Below 15mph) the brake pedal would not go down it seemed like no matter how hard I pushed the brake pedal would not move much. This caused me to run a stop sign once the truck slowed down enough and brakes were literally being pressed as hard as possible you could hear the front brakes grinding really bad and the truck still did not want to stop. I had to call a wrecker service to tow my truck to a local mechanic shop. Upon further investigation and 625 dollars later it was determined the vacuum pump failed. After replacing the pump no further issues so far.

I was backing out of an inclined driveway and when I applied the brakes, I had a hard brake pedal situation and I was not able to stop the truck until it rolled into the street. Thank goodness no car was behind me or coming down the street. I parked the vehicle and will not drive until I get to the dealer to look at. I checked the brake fluid reservoir and it was fill to appropriate level. Prior to this, 5 or 6 times, while driving, my stability control and ABS light came on but went off. Also, now that I think about it, those lights came on when the road was really pitched to one side or when I pulled into a elevated parking space.

Brakes are acting spongy, sometimes they are hard, then it goes to the floor, and makes a electronic noise.

Brake pedal got hard while trying to stop. Had no power brakes. Turn truck off and back on brake pedal works again

The vacuum pump for the brake booster fails to build vacuum at low RPM (Under 1200 RPM). The part is still on the vehicle and can be inspected when the dealer completes repairs. The failure of the vacuum pump causes the ABS system to activate when attempting to come to a stop due to the need to apply excessive brake pedal pressure. This greatly increases stopping distance and has caused me to enter controlled intersections unintentionally. The problem has been confirmed by an independent repair shop. The problem has not been confirmed by anyone else yet. There were no warnings or messages prior to the failure. The only warning was a message AFTER the failure occurred to "service brake assist system".

Recall: 19V645000 Engine Vacuum Pump Fails Reducing Power Braking Assist. Truck brakes not stopping. Air conditioner issues.

- Henderson, KY, USA

At low speeds the brakes do not engage 100% of the time. After a few short pumps the brakes dont engage and I have to push as hard as I can on the brake pedal to get the truck to stop. It has happened at random times over the last year and there is no pattern to it. It seems to brake fine when I am traveling at higher speeds but when I am parking or in stop and go traffic I have issues with stopping the truck. I believe the problem is the vacuum pump for the brakes. This issue needs to be resolved since I have read hundreds of other complaints about this same braking problem.

While driving there is a reoccurring warning of trailer brake problem. I was told this is due to a faulty waring harness, that needs to be repaired.

- Raleigh, NC, USA

My truck will start flickering and shuts off jerking the steering wheel out of my hand, then tells me to service stabilitrak. It mostly happens when I am driving (coming to a stop sign/light and/or while turning). Had it taken to two different dealers and they keep telling me it-??s a mechanical issue when It seems more electrical.

- Chatsworth , GA, USA

While traveling at low speeds, my brake pedal gets extremely stiff and brake are almost inoperable. When pressed completely down, a grinding noise is heard. It seems as though my vehicle was impacted by the manufacture brake booster defect where NHTSA determined to be a safety recall.

- Los Lunas, NM, USA

I was towing my 44 foot trailer and I suddenly got an error that the trailer and the braking system was not connected to the truck. Luckily I was not going fast and was able to still stop but I have been driving the truck also when nothing was attached to my vehicle and I get that same morning trailer brake not attached in an error. I have contacted Chevrolet and they say there is nothing wrong there-??s no recall on it but if you get online and all the places were the owners of General Motors trucks you will find numerous complaints about this problem they say they cannot duplicate this at the shops. But it continues to happen they say replace this and it still happens replace that and it still happens there-??s a major problem somewhere and I imagine there have been accidents due to this error. I think it needs to be looked at from what I can tell it has not been I also had owned a GMC 20 14. 1/2 ton pick up and it had the same problem and I got the same answers. I reported this problem with my 2014 GMC 3-4 yrs ago

At low speeds I lose all pressure in my brake pedal and it goes very hard. I have to use every bit of force in my body to stop the car. There is already a recall for this issue with the vacuum pump for my year make and model however my VIN is not part of it. I tried to call General Motors about this and was told I am not part of the recall. When I asked to escalate the issue to someone dealing with the recall so they can be aware that it is affecting more vehicles than they think I was told I can't escalate it and was hung up on.

loss of braking in reverse, hard pedal feel, unable to stop. no warning lights or DTC codes

- Purcellville, VA, USA

When slowing down vehicle to stop at traffic light or pull in parking space, brakes are failing and feels like vehicle has no brakes..have to press down on brake pedal really hard and as far down as it will go before vehicle will stop. Only happens at these lower speeds such as while trying to park or stop at a traffic light. We have had the brake pads, rotors, calipers, etc checked..everything looks good so this is not the problem. There were no warning lamps or messages associated with this problem..it has happened the last 2 times we have driven the vehicle..we are not driving it anymore at the moment until we figure out was is going on. Afraid we will hit something or someone else if we cannot get the vehicle stopped in time. Looking online seems there were several recalls for this problem for this vehicle but I never received a notice for it..possibly a bad vacuum pump or ABS defect? Needs to be reset or something..Please advise. Thank you.

Brakes aren-??t properly working at low speeds like stop and go traffic or waiting in line at a gate. They vibrate like the pump is bad or something but brakes work fine when driving at normal speeds.

- Chesapeake , VA, USA

The brake system fails when operating at extremely slow speeds (i.e., at drive throughs and while parking). Brake pedal becomes rigid and difficult to engage. When engaging the foot break the vehicle continues to roll and is unresponsive resulting in the vehicle to continue moving. Service appointment is scheduled for 7/14/21 at a certified Chevrolet dealer/service provider.

Losing breaks at low speed, there was a recall in Canada for this issue

- Barnwell, SC, USA

Additional brake pedal effort needed at low speeds. If truck is at idol and or in traffic brake pedal becomes extremely stiff and requires a tremendous amount of effort to stop.
