First sign of problem was Thursday night, 10/7/2021. When on an incline there is no brake vacuum assist, takes both feet and all the force I can apply to stop vehicle going very slow. On flat surface it feels different than normal, when applying brakes there is a feeling of rough resistance but the brakes do work almost as normal. I see there is a recall for brake assist pump that is fixed by software update. I have only owned this vehicle since July of this year. I have checked the NHTSA data base and it shows no non-repaired recalls. I do not know how to confirm if a recall notice was actually sent out on this vehicle. This is not a random occurrence, it started Thursday and has not stopped. I am afraid to drive this vehicle for fear of dying.

Brakes hard to push and make a grinding noise when going at slower speeds. Like in parking lots, red lights or at a drive thru. It sounds like when the antilock breaking system kicks in. This is causing the vehicle to take a farther distance to stop.

While applying brake pedal pressure at slow speeds (under 15 mph), and while in reverse gear, my 2016 Chevrolet Tahoe ls fails to stop. The brake pedal also appears to lose power assist and will not depress even under extreme foot pressure applications. This results in the vehicle continuing to roll uncontrollably. The condition also occurs when in drive (albeit not as frequently as while in reverse) and also at slow speed. Vehicle was brought in to atlantic Chevrolet (NY) for a recall but the condition was not rectified. This condition occurs intermittently but is extremely precarious in proximity to pedestrians and other vehicular traffic. Recall # N192268490 NHTSA campaign number: 19V645 and 20V603

On January 29, 2021, my 2016 Tahoe lt, with 69,676 miles, experienced a "brake vacuum assist pump failure". the vehicle was on a flat surface (driveway), in reverse, moving very slowly backward, when I engaged the foot brake pedal it was hard and would not stop the vehicle immediately, the vehicle eventually stopped after an abnormal distance (without warning the brakes failed to engage). Once I stopped, I turned off the ignition, waited a few minutes, then started the ignition and no warning sensors/ lights were displayed. I then placed the vehicle in drive to check the brakes. I moved forward slowly, when I pushed the foot brake pedal it was once again hard causing me to pump the brakes which caused the brake pedal to become fluttering and the pedal was pushed to the floor, the vehicle eventually stopped after an abnormal distance (without warning the brakes failed to engage). Because of the severe safety risk, I had no choice but to replace the 'brake vacuum assist pump' on February 2, 2022, at my cost.

Its seems that the ABS computer stopped working and the break and traction control assist also.

Vehicle experiences delayed stopping at low speeds. The initial incident occurred on 10/16/20 while approaching a 4 way stop--the vehicle rolled thru the stop. On 10/21/20 it occurred again while parking the vehicle, pulled up slightly and stopped to put in reverse, but the vehicle continued to roll. No accidents occurred in these situations as no other vehicles were around. Owner's husband inspected brake pads and all were within specification and brake fluid was at appropriate level--noted that when the break pedal was depressed multiple times the pressure could be felt building at the pedal but vehicle would still roll.

As I approached a red light the brake pedal depressed nearly to the floor and with no warning a popping noise sounded from the vehicle followed by the brake pedal suddenly depressing completely into the floor. I was able to safely pull the vehicle to the side of the road and get the vehicle to a safe location given the lack of braking abilities. This is a several ton vehicle and I expect the brakes to work at all times. This is unacceptable. I brought the vehicle to the dealer once before to remedy this recall but it was clearly not fixed. The loss of braking ability was followed by a message on the dash stating "service braking system immediately", followed by "service brake assist". a light illuminated on the dash as well and I am unsure of the specific meaning of this light. A second light showing "ABS" was flashing to also catch my attention to the current issue at hand.

In several instances the 2016 Tahoe ltz will not stop if you are going slow like in a drive thru or picking up kids from school I have had the Tahoe in for the reprogramming of the vacuum pump but it still does it noticed it the other day when backing the boat in the water I have had it to the dealership a couple of times I have had the back brake calibers replaced at my own expense I have contacted the dealership a few times to tell them that the recall they said they fixed is still not fixed they said they did what the recall called for I am just letting you know that I do not think the reprogramming works it is still an issue I am for certain this is not the fix for the 2016 Chevy Tahoe brake vacuum pump problem.

Took vehicle to dealership for engine light and complete power loss while driving 70mph on highway. Was told uneven wear on brakes, that they needed to be replaced soon (25083, miles on vehicle)they did not inform me of the notice about uneven front brake pad wear bulletin #pit5377D. Anaow at latest check, metal to metal, was informed of the bullein from a brake place. Dealership was well aware of vehicle having defective pads and rotors, yet didnot inform customer!

I have an issue with my Tahoe and I noticed some other vehicles have the same issue but mine doesn't have that recall. I been seeing service brake assist on my display, and with that I have problems stopping my vehicle at a slow speed. It usually happens when I'm backing up out of my garage, or trying to park at a parking space. I have to press down on the pedal hard to stop, at one time I had to pur it in neutral cause I couldn't stop. I'm afraid one of these days it won't stop and I will cause an accident or damages cause of this issue. Like I said I don't understand why other vehicles with the same issue have recall, I researched and it seems that from 2015 to 2017 they have recalls. I would like to get this issue fixed.

Just recently got my brakes re-programmed and immediately they continued not to function correctly. The warning lights don't come on but they still do not stop in time. In a parking lot I could not stop and hit a sign in front of the parking space. Will Chevrolet fix the damage caused by my car. Also noted in a drive-through cannot get stopped in time when trying to follow cars. And it backing down a hill at slower speeds car will not stop. Brakes just shake when you try to push them. Thinking of getting an attorney because I need someone to fix my car now

On two separate occasions I have lost control of the vehicle. The first time I was turning and thought maybe I hit a slick spot on the road but the same thing did not happen to other cars. The second time I was driving straight on a secondary road and out of nowhere the car started sliding like it was on ice but the brakes and steering were non functional. I could turn the wheel and press the brakes but nothing happened. There was no indication that there were any issues with the car, no alarms or messages came up before, during, or after the incidents. I was very lucky in both instances in that there were no oncoming cars. This has been extremely terrifying and I refuse to drive the car anymore. Heaven forbid my children or anyone else had been in the car.

I am a police fleet manager that has an all Chevy Tahoe fleet. In October 2019, I received notification for Chevy recall N192268490 and every vehicle in the fleet was taken in for the recall. The recall was to reprogram the brakes, so braking would still be possible even if the brake booster failed. However, the recall did not address the root of the problem, which is a faulty secondary hydraulic brake assist vacuum pump. I was aware of this problem because I had two Tahoe already have a vacuum booster failure, which resulted in an extremely hard brake pedal which would not stop the vehicle. The problem arises during slow speed braking, such as parking lots or slow speed patrol. Less than a week after taking the vehicles to Chevy for the recall, an officer was maneuvering slowly in a parking lot. The vehicle experienced an extremely hard brake pedal and the vehicle failed to stop. The officer was able to turn the vehicle, barely avoiding a collision. Obviously, GM's band-aid recall does not fix or even override the problem. The vehicle was taken back to the dealership, where the service providers agreed the recall was a placebo and there is an issue with the vacuum booster. As per a recent letter from GM, they have given an extended warranty on the vacuum pump, for free replacement. So, obviously they know there is a problem. The liability placed on municipalities, who have no other choice but to use their fleet vehicles with known braking issues, is an unfair burden and risk. GM needs to recall and replace the vacuum boosters!

Hello my Tahoe was in a Chevrolet dealer on October 25 because of a brake recall, the truck was 'fixed' that same day. The only thing is that my truck won't start anymore since then. I had my truck parked in a garage since the day we got home from the dealer and today 11/13/19 when I get to turn it on it just won't start. Also my husband had a car accident due to the brakes not working in April of this year before we knew the truck was on recall. He was in a city street and he tried to brake because the car in front of his was making a stop the brakes just didn't work, he tried to avoid the car by turning to his left but the front side our truck hit the back of the car. I have all the information of the insurance when the accident happened. Thank you hope to hear from you soon.
