2016 Chevrolet Tahoe Brakes Problems

Your brake pedal feels soft and sinks almost to the floor when you press it, though this happens only sometimes and comes back repeatedly. Your ABS and stability control warning lights turn on, and sometimes they flash. A dealer diagnosed the problem as a faulty Electronic Brake Control module, which was replaced to fix the issue. This repair may involve replacing the brake control module and checking the brake fluid system.

Your brake assist system is intermittently stopping working, and the brake assist warning light comes on occasionally. Even though records indicate all recalls have been completed, you suspect the vacuum brake issue from a previous recall may not have been properly repaired. The underlying problem likely involves the vacuum system that powers your brake assist, and a technician will need to inspect and potentially rebuild or replace the vacuum pump and related brake components.

Brake vacuum pump

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.

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

The contact owns a 2016 Chevrolet Tahoe. The contact stated that while operating the vehicle, the stabili-trak, ABS and traction control warning lights remained illuminated, and the vehicle would not immediately stop while depressing the brake pedal. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the ABS module and ABS pump were faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were not notified of the failure. The failure mileage was 150,000.

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).

The contact owns a 2016 Chevrolet Tahoe. The contact stated that while driving at slow speeds, the brake pedal went to the floorboard while depressed. While driving 10–15 MPH, the brakes operated as designed. There were no warning lights illuminated. The vehicle was taken to an independent mechanic and the brakes were replaced; however, the failure persisted. The vehicle was taken to the local dealer and the contact was informed that the VIN was not under recall for the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline for assistance. The contact referenced the NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic) as a possible cause for the failure. The failure mileage was approximately 75,000.

I was driving down highway and saw a wall of cars and brake lights in the distance, so naturally my foot tried to push the brakes. The pedal was hard, and I panicked because my tahoe was not stopping at all! I continued to stomp on brake pedal all the way until my car actually hit 3 vehicles and then the guardrail! My brakes did not work , because if they did then I would have easily prevented this accident!!

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.

Brakes barely stop at low speed

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.

The contact owns a 2016 Chevrolet Tahoe. The contact stated that on numerous occasions while the brake pedal was depressed, added pressure was needed on the brake pedal to stop the vehicle. The contact stated that after shifting to park, the brake pedal returned to normal operation. No warning lights were illuminated. The vehicle was not diagnosed nor repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 75,000.

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.

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

The contact owns a 2016 Chevrolet Tahoe. The contact stated that while driving at various low speeds and needing to apply the brake pedal, the brake pedal was difficult to depress. The contact then stated that the failure was reoccurring and that excessive force was required to depress the brake pedal. No warning lights were illuminated. The vehicle was taken to an independent mechanic, however, the vehicle was not diagnosed or repaired. The contact was then made aware of NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic) however, the local dealer confirmed that the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 80,000.

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

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.

The contact owns a 2016 Chevrolet Tahoe. The contact stated that while depressing the brake pedal, the vehicle would not immediately stop, and the stopping distance was extended. The contact indicated that on several occasions the brake pedal was firm and hard when pressed. On other occasions the pedal would extend to the floor. The vehicle was taken to the dealer and serviced under the NHTSA campaign number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control) however, the failure persisted. The contact also indicated that the transmission was faulty. After taking the vehicle to the dealer no trouble code was found. No further information was available. The failure mileage was 26,000.

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.

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. *TR

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.

TL* THE CONTACT OWNS A 2016 CHEVROLET TAHOE. WHILE DRIVING 5 MPH, THE VEHICLE SHOOK WHEN THE BRAKE PEDAL WAS DEPRESSED. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC). THE CONTACT STATED THAT ANTELOPE VALLEY CHEVROLET (LOCATED AT 1160 MOTOR LN, LANCASTER, CA 93534, (877) 385-0885) EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE AND FILED CLAIM NUMBER: [XXX]. THE PART WAS NOT AVAILABLE FOR THE REPAIR. THE FAILURE MILEAGE WAS UNKNOWN. PARTS DISTRIBUTION DISCONNECT. *LN *JS PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

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

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! *JS

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.

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 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.

TL* THE CONTACT OWNS A 2016 CHEVROLET TAHOE. THE CONTACT STATED THAT THE BRAKES DID NOT WORK WHILE DRIVING AT SLOW SPEEDS. OBX CHEVROLET BUICK (6166 N C CROATAN HWY, KITTY HAWK, NC 27949, (252) 429-5552) DIAGNOSED THAT THE BRAKE BOOSTERS FAILED. THE MANUFACTURER STATED THAT THE VEHICLE WAS NOT INCLUDED IN A RECALL. THE FAILURE MILEAGE WAS 20,000.

TL* THE CONTACT OWNS A 2016 CHEVROLET TAHOE. WHILE DRIVING VARIOUS SPEEDS, THE BRAKE PEDAL WAS APPLIED, BUT WAS DIFFICULT TO DEPRESS. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO DARLING'S CHEVROLET (121 DOWNEAST HWY, ELLSWORTH, ME 04605, 866-575-2434) WHERE IT WAS DIAGNOSED THAT THE VACUUM PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND PROVIDED CASE NUMBER: 95099372350. THE FAILURE MILEAGE WAS 69,800.

BREAKS FAILED ON TWO SEPARATE OCCASIONS APPROXIMATELY 3 WEEKS APART WHILE ATTEMPTING TO STOP COMING INTO THE GARAGE. BREAKS WORKED FINE PULLING INTO THE DRIVEWAY.

WHEN DRIVING AT SLOW SPEEDS AS IN A PARKING LOT THE BRAKES FAIL TO STOP TRUCK. THIS HAPPENED THREE TIMES WITH IN A 30 MINUTE TIME PERIOD.

TL* THE CONTACT OWNS A 2016 CHEVROLET TAHOE. WHILE DRIVING AT LOW SPEEDS, THE BRAKE PEDAL WAS DEPRESSED, BUT FAILED TO OPERATE AS INTENDED. THE VEHICLE WAS TAKEN TO HEINRICH CHEVROLET (LOCATED AT 5775 S TRANSIT RD, LOCKPORT, NY 14094, (716)-514-4134) WHERE IT WAS DIAGNOSED THAT THERE WAS AN INTERNAL OPENING IN THE VACUUM PUMP, WHICH CAUSED THE FAILURE WHILE BRAKING. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 57,361.

WHEN DRIVING AT SLOW SPEEDS, PARTICULARLY TO PARK, THE BRAKES DID NOT WORK. YOU CAN PUT THE PEDAL TO THE FLOOR AND THE VEHICLE KEEPS GOING. THIS ONLY OCCURS WHEN AT A SLOWER SPEED, IN BOTH DRIVE AND REVERSE. I HAVE TAKEN IT TO A MECHANIC AND THE VACUUM PUMP HAS TO BE REPLACED. THIS IS VERY DANGEROUS AND COULD HAVE CAUSED AN ACCIDENT, AS I ALMOST HIT ANOTHER CAR BECAUSE I COULDN'T STOP.

WE TOOK A FAMILY VACATION TO NY AND ALMOST DIED BECAUSE OUR BRAKES WENT OUT. IF YOU RESEARCH 100'S OF PEOPLE HAVE HAD THEIR 2016 TAHOE BRAKE PUMP FAIL. I AM ALSO EXPERIENCE MY CAR JERKING. I AM BEYOND MYSELF THAT A RECALL HASN'T BEEN ISSUED BECAUSE I AM GETTING READY TO GO PAY FOR A PART THAT IS FAULTY. YOU WANT TO MAKE THIS RECALL FAST OR PEOPLE WILL DIE. YOU CANNOT HAVE YOUR BRAKES GO OUT LIKE THAT!! I DIDN'T SPEND $50K ON A CASH LESS THAN 2 YEARS AGO FOR MY FAMILY TO DIE.

I AM EXPERIENCING LOSS OF BRAKE BOOSTER FUNCTION AT LOW SPEEDS. I HAVE READ ABOUT THE VACUUM PUMP AND THE CONDITIONS MATCH EXACTLY

TL* THE CONTACT OWNS A 2016 CHEVROLET TAHOE. WHILE DRIVING 5 MPH, THE BRAKE PEDAL WAS DEPRESSED AND TRAVELED TO THE FLOORBOARD. THE VEHICLE WAS TAKEN TO RICK HENDRIX CHEVROLET (LOCATED AT 5665 AIRPORT-PULLING RD, NAPLES, FL 34109, (239) 301-3621) WHERE IT WAS DIAGNOSED THAT THE BRAKE BOOSTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 40,250.

WHEN DRIVING AT LOW SPEEDS AFTER I DEPRESS THE BRAKE PEDAL A FEW TIMES, THE BRAKE PEDAL GETS VERY STIFF AND IS ALMOST IMPOSSIBLE TO STOP THE VEHICLE.

BRAKES FAILED TO ENGAGE ON THE VEHICLE WHEN PRESSURE APPLIED. OCCURRED MULTIPLE TIMES. GM FAILS TO ACKNOWLEDGE THIS AS A KNOWN AND WIDESPREAD ISSUE, YET WITH A SIMPLE GOOGLE SEARCH, YOU CAN SEE IT HAS AFFECTED NUMEROUS PEOPLE AND VEHICLES. SOUNDS LIKE A RECALL SHOULD HAVE BEEN ISSUED BY NOW BUT YET THERE ARE NONE.

ENGINE HAS BEEN MAKING A CLICKING SOUND FOR THE LAST YEAR. WE TOOK IT IN AND THEY WERE UNABLE TO PINPOINT THE PROBLEM. WITHIN THE LAST COUPLE MONTHS THE BRAKES SEEM MUSHY WHEN PRESSED AT LOW SPEEDS, SUCH AS DRIVING INTO THE GARAGE OR A PARKING SPACE. WE HAVE TO PUSH THE BREAK PEDAL DOWN TO THE FLOOR FOR THE VEHICLE TO STOP. WE ALMOST RAN INTO THE WALL IN THE GARAGE BECAUSE THE VEHICLE WOULDN'T STOP WHEN THE BRAKES WERE PRESSED. WE TOOK IT IN AND THEY INFORMED US THAT THERE WAS A LEAK IN THE BRAKE VACUUM PUMP. MOSTLY LIKELY THIS IS WHY THE ENGINE HAS BEEN MAKING A TICKING SOUND, BECAUSE OF THE LEAK.

I HAVE EXPERIENCED "HARD BRAKING" OF MY VEHICLE. WHILE TRAVELING AT VERY SLOW SPEEDS, WHEN I BRAKE - THE BRAKE PEDAL DOES NOT GO DOWN IN ITS NORMAL FASHION. I MUST APPLY THE BRAKES VERY HARD, AND THE VEHICLE FEELS LIKE ITS NOT GOING TO STOP. I HAD RECENTLY READ ABOUT THIS PROBLEM AND DOCUMENT THIS HAPPENED TO ME ON NUMEROUS OCCASIONS. IT HAPPENED AS RECENTLY AS YESTERDAY.

BRAKES FAILED 3 TIMES, ONCE PULLING INTO PARKING SPACE, I ROLLED DOWN A STEP DRIVEWAY INTO STREET ACROSS STREET AND INTO NEIGHBORS YARD AND ONCE WHEN A TECH FROM DEALERSHIP WAS TEST DRIVING IT, HE ALMOST HIT THE BUILDING.THE VEHICLE WAS IN MOTION EACH INCIDENT.

BRAKES DO NOT WORK WHEN GOING AT A SLOW PACE. HAVE TAKEN THE CAR IN 2X AND THEY CANNOT FIN ANYTHING WRONG. JUST TOOK IN FOR 3RD TIME AND THIS TIME I DROVE IN THE CAR WITH THEM. THEY CONFIRMED THEY BRAKES ARE NOT WORKING PROPERLY.

BRAKES CONSISTENTLY SOFT PRESSURE ESPECIALLY ON DOWNGRADES. CAME CLOSE TO HITTING PARKED CARS AT TRAFFIC LIGHTS. BRAKE WAS PRESSED ALMOST TO THE FLOOR BEFORE IT STOPPED. I HAVE TAKEN IT INTO DEALERSHIP WHERE THEY HAVE CHANGED PADS FIXED ROTORS BUT STILL VERY SOFT MUSHY BRAKES. MANY COMPLAINTS I AM READING ABOUT THIS 2016 TAHOE. WHEN PARKED PRESSING BRAKE 3 TIMES IS WHEN IT FINALLY FEELS LIKE IT IS IN CORRECT POSITION. I OWED 2008 SUBURBAN FOR 10 YEARS AND HAD NO PROBLEMS WITH THE BRAKING SYSTEM.

AT SLOW SPEEDS THE VEHICLE DOES NOT BRAKE. TO GET THE VEHICLE TO STOP YOU HAVE TO TAP THEM REPEATEDLY VERY HARD FOR IT TO ACKNOWLEDGE THAT YOU ARE BRAKING.

WHEN DRIVING AT LOW SPEEDS, BOTH TURNING AND DRIVING STRAIGHT, THE BRAKE PEDAL BECOMES SO FIRM THAT IT CANNOT BE DEPRESSED. I AM UNABLE TO STOP THE VEHICLE WITHOUT PUMPING THE BRAKES. THE DEALERSHIP IS CHARGING $700 TO REPLACE THE VACUUM PUMP AND IS FAMILIAR WITH THE ISSUE.

WHILE DRIVING AT SLOW SPEEDS OR IDLING, MY BRAKE PEDAL BECOMES STIFF AND HARD TO PUSH, MAKING IT VERY DIFFICULT TO STOP. THIS HAS HAPPENED MOSTLY WHEN I AM PULLING IN TO A PARKING SPOT. THERE WAS NO EMERGENCY ALERT SHOWING.

WAS INVOLVED IN A AUTO ACCIDENT IN SEPT 2017 IN WHICH I REAR ENDED ANOTHER VEHICLE.I WAS TRAVELING SOUTHBOUND ON GREENMOUNT ROAD IN SHILOH IL. COMING TO A STOP AT A STOPLIGHT AT ABOUT 30 MPH, I WAS TRYING TO KILL A SPIDER SO MY EYES WERE OFF THE ROAD BUT WHEN THE COLLISION ALERT ALARM SOUNDED I IMMEDIETLY HIT THE BRAKES WHICH WERE HARD MAKING BRAKING DIFFICULT THERE IS NO WAY AN IMPACT SHOULD HAVE HAPPENDED. WHEN THE COLLISION ALERT ALARM SOUNDS THE BRAKE PEDALS BECAME HARD MAKING THE STOPPING OF THE CHEVY TAHOE IMPOSSIBLE SO I COULD NOT AVOID REAR ENDING OF THE VEHICLE IN FRONT OF ME. NOW WHILE DRIVING THE TAHOE WITHOUT THE COLLISION ALERT ACTIVATED THE SUV STOPS LIKE NORMAL, ONLY WHEN THE COLLISION ALERT IS ACTIVATED DOES THE HARD BRAKE PEDALS OCCUR WHICH TO ME IS THE OPPOSITE EFFECT.

LOSS OF BRAKE POWER AT LOW SPEEDS. TOOK A LONG DISTANCE, LONGER THAN NORMAL FOR THE VEHICLE TO FINALLY STOP. ALMOST HIT NUMEROUS CARS. I HAD TO APPLY THE PARKING BRAKE IN ORDER TO AVOID HITTING A FAMILY IN THE PARKING LOT AT DISNEYLAND, IN ANAHEIM, CA AND OTHER CARS. HAD THE TAHOE TOWED TO OUR DEALERSHIP, WHERE THEY REPLACED THE VACUUM PUMP ASSEMBLY.

BRAKES GOT HARD WHEN DRIVING ONTO EXPRESSWAY TAHOE HAS ONLY 42000 MILES AND HEARD THERES BEEN ALOT OF ISSUES WITH THE VACUUM PUMP WHAT I HAVE READ.THERE NEEDS TO BE A RECALL
