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.
2016 Chevrolet Tahoe brakes complaints
Page 3 of 4: complaints 41 to 70 of 92, newest first, as owners wrote them.
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.
Brake pedal becomes hard to stop at slower speeds. Vacuum booster is not working properly. Just started this week.

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 tahoes 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.

Tl* the contact owns a 2016 chevrolet tahoe. While driving approximately 25 MPH, the vehicle did not immediately stop when the brake pedal was depressed and crashed into another vehicle. There were no injuries and a police report was filed. The cause of the failure was not determined. The manufacturer was not notified. The vehicle was towed and serviced at hendrix chevrolet (1500 savannah hwy, charleston, sc) for the brake failure. The failure mileage was 58,000.
At low speed (gridlock traffic), brake pedal became very difficult to press and would not fully stop the vehicle
After vehicle has been parked, when put in reverse trying to back out of a parking space the brakes do not activate and barely can get the vehicle stopped. . It has happened multiple times. Feel like I can't get the vehicle stopped even pressing or pumping the beakes!! It's a matter of time before I hit something. Very scary! When I shift it into drive to go forward they work just fine.
Brake pedal became extremely hard to push first instance was slowing to make a right hand turn after nearly crashing got vehicle stopped after sitting for a while brakes returned to normal operation. Second instance backing into parking space petel went to floor no brakes then petal came up and was extremely hard to press down hitting another vehicle in the process. After a period of time brakes went back to normal operation.
Truck mileage is 48k. Drove about 8 miles to restaurant for dinner and all was normal. Came out of restaurant and started truck in parking garage and steering wheel wouldn't budge without great effort and then only in half inch increments. Took a cab home and and had truck towed to sport chevrolet for service. Brakes required replacement of the vacuum pump under warranty. The steering rack had to be replaced for $2880 not under warranty. Issue is sudden total steering rack failure with no graceful degradation. If it had happen at highway speed I wouldn't be here to report the failure.
Brakes felt like they were slipping and the vehicle would continue to roll for a minimum of 5 feet. "service brake assist" message was shown and the brake module was replaced. Vehicle was in motion 24 hours after replacing module on a major highway and "service brake assist" appeared on the dash. Brake pedal was hard and braking system was completely inoperable.
At slow speeds brake hits the bottom and vehicle doesn't stop. Dealer admits brake vacuum failure.
Lost power to brakes - difficulty stopping at low speeds - nearly hit car in front of me - car felt like it would not stop
Hi im writing again to report on 2016 chevy tahoe vacumm asst failure / defective parts the tahoe had at the time of the crash 40,475! I had just picked up my vehicle from service at jack schmitt chevrolet for unrelated issue I was 2 miles from the dealership heading southbound on green mount rd. Approaching a stop light I was slowing down coming up to the light when spider fell between my legs so I attempted to kill it at the same time the collision alert activated and I immediately hit the brakes but the pedal was hard and the SUV was not stopping like I thought it should so I started making evasive action to avoid rear ending the car at the light. I pulled the steering wheel all the way to the right but the SUV kept moving not slowing as it should have and hit rear passenger side back oh the car in front of me causing nominal damage to both vehicles about 12,000 for the tahoe which I got repaired so I chalk it up as my fault but I kept noticing the SUV on several occasions seemed like it was still moving when it should stopped. Months passed and I was looking up possible causes and on a web site a complaint made by somebody who's tahoe was doing the same thing that's when I filed a claim with chevy/gm somewhere around june 20 2018 and spoke monique hill who took my report and months later denied my claim and in the same letter said get your vacum asst serviced and I thought that was strange! Anyway I did get it serviced at jack schmitt chevy in ofallon il 6186252800 and was told the vacuum assist was defective and they had to order the parts to repair also they had to give me a car rental because the 2016 chevy tahoe was unsafe for the road and that would be held liable if they let me take it and I'm pissed at that point all this time I could have been killed! I was hurt and hurt for about a year sure back and neck and they just denied denied denied! Please help
Brake failure/ hard brake required to stop vehicle. Vacuum pump failed.
Experienced spongy/soft pedal and increased stopping distance. Took vehicle to dealer thinking it needed new brakes and was told it needed a new vacuum pump, booster and master cylinder at a cost of $1,400. I was told that this was a known issue with several gm models but the vehicle was 2,500 miles/10 days out of warranty at the time.
At very low speeds, brakes do not work. Backing out of drive, pulling into garage, waiting in traffic on a hill. Push down on breaks and nothing stops. Works fine when at normal speeds. Dealership could not create issue at their site. Has happened 10+ times at home and in parking lots and in traffic jams. Began noticing around 40000 miles. Vehicle at 49000 miles now.
