This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
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".
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.
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.

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.
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.
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.
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.
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.
My Silverado has already had the software upgrade related to the previous vacuum pump/brake recall (N192268490). It initially helped, but now the brake pedal is again extremely hard to press at slow speeds, such as in traffic. You need to almost stand on it to stop. It appears that the deterioration is back where it was before the software "fix." I will be taking to the dealership this week and requesting a replacement of the vacuum pump under warranty or recall. I am beyond regular powertrain warranty at this point, but brakes seem like they should work past 80K.
When driving at a low speed while parking or in traffic, my brake pedal either gets very hard or very soft and feels as if though I have no braking power. It feels like they are trying to brake but don't have enough force to stop the vehicle. This has happened on numerous occasions, I have almost hit cars in traffic or cars in parking lots while parking because the brakes can not be fully engaged. I have replaced all my brakes and rotors and have had everything inspected and have been told it may be the vaccum pump on a car that has only 56K miles. This is a very serious safety concern that the dealer is refusing to recognize as faulty. I have had to use my parking brake just to get home. Now my car sits because it is unsafe to drive and the dealer quoted over 1700 to fix.
After a 300 mile drive the brakes all but failed when attempting to back into a parking spot. The pedal was stiff feeling and required significant pressure to stop. Going forward seemed to be normal then when I backed up again it was bad. This has occurred a few times now. The latest was just before christmas, waiting in line for a drive thru pickup and after 20 mins when we moved forward the vehicle was very difficult to stop.
