2016 Chevrolet Tahoe Brakes

There are times that the brake assist will stop working. The bake assist light has started coming on once in a while. I looked up the vin and it said all recalls were repaired. I have a concern that the vaccume brake issue was not properly taken care of at whatever dealership that claimed to fix the issue.

Brake vacuum pump

Increased breaking effort, vehicle didn’t and currently doesn’t allow me to stop as quickly as needed Aligns with recall number: 19V645000

I called my local Chevrolet dealership to get the recalled on my Tahoe fixed and they can’t fix the recall for a full month. I’m very concerned because it’s a recall on the vacuum pump so it affects my brakes. My truck is a daily driver so I will have to gamble for a month on the streets and pray the brakes don’t get any worse.

While pulling up to the drive thru window to pick up our food, at very low speed, vehicle would not stop had put all of my body weight on brake pedal to get it to stop and avoid hitting car in front of us.

Brake Assist failure at low speed making vehicle extremely hard to stop. GM recall N182202780 does not cover all VIN numbers of the model years affected. GM states this VIN number is not covered yet the vehicle has the exact failure outlined in this recall.

While driving at low speeds, the brake pedal became very difficult to engage and the car did not stop as intended. This affects the ability of the vehicle to stop in areas with frequent pedestrian traffic such as driveways and parking lots creating a substantial safety risk. The vehicle has not been to a repair shop or dealership to investigate further at this time. There are no warning lights or messages from the vehicle computer system. This issue sounds like an issue researched on the internet for Chevy vehicles, but this VIN is not covered by a prior recall. The symptoms seem to be the same as described in NHTSA Campaign Number 19V645000 (Service Brakes, Hydraulic).

While driving at low speeds, the brake pedal became very difficult to engage and the car did not stop as intended. This affects the ability of the vehicle to stop in areas with frequent pedestrian traffic such as driveways and parking lots creating a substantial safety risk. The "Service Brake Assist" message also appeared after this incident. I contacted my Chevrolet dealer who cannot schedule an appointment for at least 15 days. The car is currently at an independent mechanic who advised that this sounds like a familiar issue for Chevy vehicles, but this VIN is not covered by a prior recall. The issue seems to be the same as described in NHTSA Campaign Number 19V645000 (Service Brakes, Hydraulic).

Brakes barely stop at low speed

Purchased the car new for a local dealer in Surprise, Arizona. Over time the brake pedal has become spongy, soft and pulsating. This happens mostly at slow speeds like backing out of the driveway or garage. Did a search of the NHTSA web site and see that there was a recall on my model year vehicle to replace or reprogram the vacuum pump. However I never received a recall notice. I am now afraid to drive the car because I am concerned over a complete brake failure. I do know that during one of my normal service maintenance appointments I was approached by the service advisor about his concern over a suspected brake issue. He wanted to replace my entire brake system, master cylinder, vacuum pump, etc for a cost of about $1,500 as I recall. I declined the repair as I was not aware of that the problem I was experiencing was including in the recall. Again I never received any notice of a recall of the vacuum pump for the brakes but clearly I am experiencing the symptoms as was described in the recall notice on your website.

I bought this 2016 Tahoe in January of 2023. I was very excited to purchase my first Tahoe and sunk my savings into paying for it. A couple weeks after I purchased it, I got a service trailer break message that came up on my screen. I have had several different mechanics look at it, but still, it hasn't been fixed. This message pops up probably 60 times while I am driving, and continuously. It flashes across my screen, and when I dismiss it, it will go away for a second and then pop up again. This dinging message continues while I'm driving it. I feel that it is a safety hazard as I am very distracted by it when I am driving the car. I don't have any other choice, as I spent all my money I had for a car on purchasing this car, and don't have another car to drive, so I have to drive this one. I would really like for GM to issue a recall for this, and tell technicians how to fix this. The technicians I have seen tried replacing the battery and a corroded wire. We've replaced the switch, but still this message returns. I am very frustrated by this, as I traded my old car in for this one, because I was having car trouble. I wanted to trade to avoid car problems, but just got a car with more problems. I am going insane with this message and not having a fix for it.

Brakes failed to work at low speed. Traveling in stop and go traffic on I-40 and the brake pedal became hard as a rock and was pulsing. Had to pull over and coast to a stop. Performed a test on the median of the highway and again the brakes failed to work. We were towed to the repair shop. Awaiting the repair diagnosis and cost.

The break pedal pivot nut loosened to the point where it fell off and the break pedal became inoperative.

Frequent vacuum brake failure. The brake pedal goes all the way to the floor.

When I apply the brake it goes to the floor, I have to pump my brake pedal. Once the Tahoe slows to a stop it rolls forward as the brake is still engaged and pressed to the floor. When backing up in reverse the brakes grind when using a downhill grade. Lastly the brake assist light has illuminated on the control panel.

Brakes do not work when driving in slow speeds. I could not stop my 2016 Tahoe in a shopping center parking lot. Pedal was stiff and non responsive. I had the same issue parking in my garage. Vehicle did not stop and went into the wall!!

When driving at low speed (parking lots i.e.) brakes don’t work properly and the brake assist message pops up on dash, it only happens at very low speed

Slow speed braking problems brakes don’t work good at slow speeds

Braking causes vehicle to accelerate

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.

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.

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

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.
