2016 GMC Yukon Brakes

On two occasions while driving at low speed, my vehicle braked on its on a pulled hard to the left; the stabilitrac indicator also popped on briefly. I went online to determine if there were any recalls on my vehicle and found that one of the recalls on the 2016 Yukon was the exact issue happening with my vehicle. I checked my VIN and found that my vehicle was not one of the vehicles with this issue. I called GM to see if my vehicle had just not been published yet. I explain the situation too the customer service person; she understood my situation and informed me that until my specific VIN in identified with this issue, there's nothing that can be done. I'm thinking that until an accident happen because of this issue, there is nothing that can be done. I read that my issue was a problem with the EBCM, which needs to be reprogrammed. I thank you for any assistance with this issue.

During standard braking operations the vehicle (not a hard emergency situation) on dry ground the vehicle seems to activate the abs system or something similar which makes the braking effort non standard and increases stopping distance. The issue has occurred occasionally for over a year but is becoming more frequent. It has occurred at both highway speeds of 55 mph and almost stopped during parking activities of 2mph.

GMC is stating that due to a recall my brake booster vacuum pump failed and now they are that is is not covered and I will be out of pocket on the issue after numerous phone called with GM they are still of no help and the vehicle is not safe to drive which is my only means of transportation

My 2016 GMC Yukon is hard to stop when pressing brake pedal. Vehicle shimmy’s when pressing the brake and it must be pressed very hard. Have read and watched many videos this is very common issue on 2014-2018 Yukons and Tahoes. This could be very dangerous and my question is, why has these vehicles not been recalled to prevent accidents when it seems to be a common issue and expensive to fix?

“Service Trailer brake system” warning continually going off when driving

Brakes will randomly stop working. When the brakes are pressed you have to press all the way down and then vehicle still won’t stop and the only way for the vehicle to come to a complete stop is to press the parking brake. Brakes and rotors have been replaced already and it still happens

Vacuum

2016 GMC Yukon. I received a letter that stated my Yukon may have a condition where the brake lights intermittently do not illuminate. In March 2020 the drivers side rear brake light did not illuminate. I brought it to a Chev/GMC dealer that replaced the tail light no charge. Now my passenger rear tail brake light does not illuminate. My Yukon has 68800 miles on it and it is going on 6 years old. I still have my letter I received about this issue. Without my tail/brake light it is unsafe to drive my vehicle until I get that brake unit replaced. Will I still be able to my passenger side brake unit replaced at no charge? I haven’t been able to get it replaced due to I had total knee replacement surgery in February 2022

The trailer break service light is coming on. There is not a way to dismiss the sound and comes on every few seconds, it's very distracting a HUGE safety risk. I have contacted GMC Valencia California and they have have several vehicles with the same issue / hazard. This has apparently been going on for years yet GMC refuses to put a recall on the vehicles nor take action on correcting this on this critical issue. This is very upsetting and with all the complaints / concerns it appears nobody cares for the lives this defective issue could cause, especially when towing. Thank you.

The contact owns a 2016 GMC Yukon. The contact stated that while driving at approximately 70 mph, the brake pedal was hard to depress and the brake pedal traveled to the floorboard. The contact mentioned that the brake pedal needed to be pumped in order for the vehicle to be operated. In addition, the contact stated the vehicle failed to stop immediately. The vehicle was taken to a dealer where it was diagnosed that the brake line needed to be flushed. The vehicle was repaired however, the failure persisted. The vehicle was taken to an independent mechanic where the failure was undetermined. The contact mentioned while the mechanic was reversing the vehicle the brakes failed to operate causing the vehicle to crash into a person and a vehicle. The contact stated that the lady sustained multiple injuries that needed medical attention. A police report was filed. The vehicle was towed to the dealer where it was diagnosed that the brake vacuum pump needed to be replaced. The vehicle was repaired but the failure recurred. The vehicle was taken back to the same dealer where they informed the contact that the failure was unable to be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage 54,000.

Vacuum pump loses vacuum, and the brakes are very hard. Occurs when sitting still with the brake applied. Also occurs in reverse at low speeds. My wife refuses to drive her car, due to numerous near fender benders.

ON TWO OCCASIONS WHILE IN A DRIVE THRU LINE, I WOULD PRESS THE BRAKES AND THE BRAKE PEDAL WOULD GO TO THE FLOOR. I HAD TO BASICALLY STAND UP ON THE BRAKE PEDAL TO GET THE VEHICLE TO STOP. I HAVE NOT HAD THIS HAPPEN OTHER THAN AT A LOW RATE OF SPEED. I SEARCHED GMC YUKON FOR ANY RECALLS AND FOUND THAT THIS IS A RECALL WITH GMC. WHEN YOU DO A SEARCH OF MY VEHICLE BY VIN, IT STATES NO RECALLS ARE FOUND. I CONTACTED A LOCAL GMC DEALER AND WAS TOLD THAT THEY CAN'T DO ANYTHING UNLESS MY VIN SHOWS THE ACTIVE RECALL.

TL* THE CONTACT OWNS A 2016 GMC YUKON. WHILE ACCELERATING FROM A STOP, THE VEHICLE JERKED AND ACCELERATED INDEPENDENTLY WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE VACUUM PUMP FAILED AND NEEDED TO BE REPLACED. THE CONTACT WAS INFORMED TO TAKE THE VEHICLE TO A GMC DEALER. THE VEHICLE WAS LATER TAKEN TO JIM TAYLOR CHEVROLET (139 GRIMSHAW ST, RAYVILLE, LA 71269, (318) 303-6475) WHERE A DRIVING TEST WAS PERFORMED; HOWEVER, THE TECHNICIAN COULD NOT REPLICATE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES. THE VIN WAS INCLUDED IN NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC). THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 45,000.

THE CONTACT STATED THAT THE REMEDY SHOULD INCLUDE REPLACING THE ENGINE VACUUM PUMP INSTEAD OF REPROGRAMMING THE ELECTRONIC BRAKE CONTROL MODULE. A DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOTIFIED OF THE CONTACT'S CONCERNS. THE CONTACT HAD NOT EXPERIENCED A FAILURE.

TL* THE CONTACT OWNS A 2016 GMC YUKON. WHILE REVERSING OUT OF A PARKING LOT AT APPROXIMATELY 3 MPH, THE CONTACT FELT A VIBRATION COMING FROM THE VEHICLE. WHEN THE BRAKE PEDAL WAS DEPRESSED, IT TRAVELED TO THE FLOORBOARD WITHOUT WARNING. THE CONTACT MANAGED TO STOP THE VEHICLE WHILE THE BRAKE PEDAL WAS DEPRESSED. THE EMERGENCY BRAKE WAS NOT APPLIED. AAA WAS CONTACTED AND TOWED THE VEHICLE BACK TO THE CONTACT'S RESIDENCE. THE CONTACT STATED THAT THE FAILURE OCCURRED APPROXIMATELY THREE WEEKS AFTER OURISMAN CHEVROLET BUICK GMC OF ALEXANDRIA (1800 OLD RICHMOND HWY, ALEXANDRIA, VA 22303) UPDATED THE SERVICE BRAKES PER NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC). THE DEALER AND MANUFACTURER WERE NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 48,200.

WHILE IN SLOW TRAFFIC, I PRESSED BRAKES TO STOP. THE BRAKE PEDDLE DID NOT COMPRESS DOWN, CAUSING ME TO HAVE TO ENTER THE HIGHWAY MEDIAN TO KEEP FROM STRIKING THE VEHICLE IN FRONT OF ME. THE MEDIAN WAS WET AND MUDDY. OUR YUKON HAD TO BE PULLED FROM THE MEDIAN BY A GOOD SAMARITAN.

LOW SPEEDS THE BRAKES FAIL , WHEN PRESSING ON BRAKES YOU GET A HARD BRAKE PEDAL WITH NO BRAKES .

VEHICLE IN MOTION AND BRAKES WOULD NOT WORK UNLESS YOU PUT ALL YOUR BODY WEIGHT ON THE BRAKES, AND THEN JUST BARELY. HAPPENED MULTIPLE TIMES ON AND OFF BOTH AT HIGH RATE OF SPEED ON HIGHWAY AND ON CITY STREETS. TOOK INTO GMC DEALERSHIP AND THEY REPLACED THE VACUUM PUMP FOR THE BRAKES -- PROBLEM SOLVED AFTER SPENDING $800. WE ARE LUCKY THIS IS A MAJOR SAFETY ISSUE THAT COULD HAVE CAUSED A SERIOUS ACCIDENT. I UNDERSTAND THIS EXACT PROBLEM IS A KNOWN PROBLEM CURRENTLY BEING INVESTIGATED. PLEASE FINISH YOUR INVESTIGATION QUICKLY AND ISSUE A RECALL -- SOMEBODY IS GOING TO GET KILLED IF THIS IS NOT FIXED. I LOOK FORWARD TO BEING REIMBURSED FROM GMC WHEN THE RECALL IS FINALLY ISSUED.

VACUUM PUMP WENT OUT ON MY VEHICLE RESULTING IN ALMOST BEING HIT BY A SEMI TRAVELING 65MPH. I HAD TO CALL A WRECKER TO PICK UP MY VEHICLE AND HAVE IT TOWED TO THE DEALERSHIP AS IT WAS NO LONGER SAFE TO DRIVE. I PAID OUT OF POCKET FOR THE WRECKER AND THE REPAIR BECAUSE THE VACUUM PUMP WAS NO LONGER COVERED UNDER WARRANTY AT 38,633 MILES. I WAS LEAVING A DRIVEWAY AT A SLOW SPEED TO TURN ONTO A FARM TO MARKET ROAD AND MY BRAKES WOULD NOT WORK.

THIRD TIME THIS HAPPENED, FIRST TWO TIMES MY HUSBAND WAS DRIVING(HE CALLED THE DEALERSHIP AND THEY SAID THEY HAD NOT HEARD OF ANY PROBLEMS) AND WHEN IT HAPPENED TO ME IT WAS SCARY. I HAD MY KIDS IN THE CAR, NO INJURIES AND NO ONE WAS HURT, THANK GOD. I WAS GOING THROUGH THE DRIVE THRU STOPPED AT THE FIRST WINDOW, ACCELERATED TO NEXT WINDOW (LOW SPEED) AND DIDN'T STOP... IT WAS THE LIKE THE BRAKES LOCKED UP, COULDN'T PRESS DOWN AT ALL. CALLED THE DEALERSHIP FIRST THING IN THE MORNING, SAME THING DIDN'T KNOW OF ANY ISSUES. WELL I GOOGLED IT AND IT IS UNDER INVESTIGATION, SO I KINDLY PRINTED OFF ALL THE ARTICLES SO THEY COULD LET OTHER CUSTOMERS KNOW THERE WAS AN ISSUE (THEY DIDN'T CARE TO KEEP THAT BUT DID ADMIT THEY KNEW THERE HAD BEEN SOME ISSUES). OF COURSE MY CAR IS JUST OUT OF WARRANTY SO THEY SAID I WOULD BE RESPONSIBLE FOR ANY ISSUES. AGAIN, THIS IS A SAFETY ISSUE AND THERE SHOULD BE A RECALL!!! THEY SHOULD BE PAYING FOR IT AND THANKING THERE LUCKY STARS NO ONE WAS INJURED. THE TOTAL CAME TO $950, THEY ASKED IF I WANTED THEM TO FIX THE PUMP, BELT AND BELT KIT (I ASKED IF THIS WAS THE ISSUE OTHERS WERE HAVING AND HE SAID HE BELIEVES SO). WHAT WAS I GOING TO SAY NO? DID I REALLY HAVE AN OPTION?? THE BRAKES WEREN'T WORKING!!!! KIND OF A BIG DEAL!! OF COURSE I WOULD LIKE THEM TO PAY ME BACK (THEY DID GIVE ME A CREDIT OF $208) BUT I DO BELIEVE THEY NEED TO DO A RECALL BEFORE SOMEONE GETS HURT.

BRAKES FAIL AT LOW SPEEDS AND WHEN REVERSING SLOWLY. CAN REPLICATE PROBLEM. SEARCHED INTERNET AND THIS APPEARS TO BE A WIDESPREAD PROBLEM. SERVICE BULLETINS HAVE EVEN BEEN WRITTEN. WHY NO RECALL FOR A WIDESPREAD ISSUE THAT COULD HAVE CATASTROPHIC CONSEQUENCES. . VEHICLE HAS LESS THAN 50000 MILES.

WHEN PRESSING THE BRAKE PETAL AT LOW SPEEDS AND IN BUMPER TO BUMPER TRAFFIC THE BRAKE PEDAL BECOMES VERY HARD TO PRESS AND VERY DIFFICULT TO GET THE VEHICLE TO STOP. THIS PROBLEM ALSO IS NOTICED WHEN BACKING THE VEHICLE IN REVERSE AND INTO A PARKING SPOT.

WHILE EXITING THE OHIO TURNPIKE, MY BRAKE PEDAL BEGAN TO STOP DEPRESSING COMPLETELY- TO THE POINT WHERE I COULDN'T PUSH DOWN AT ALL. IT FELT LIKE AN OVER-PUMPED KEG. AS I CONTINUED MY EXIT TOWARD THE TOLL BOOTH, IT SEEMED THAT THE ABS WERE ENGAGING, BUT I WASN'T IN AN EMERGENCY BRAKING SITUATION. THE REST OF MY JOURNEY HOME WAS UNEVENTFUL, UNTIL I ARRIVED HOME. I PULLED INTO MY GARAGE, AND ATTEMPTED TO BACK OUT SO I CHECK UNDER THE VEHICLE TO MAKE SURE THERE WASN'T ANYTHING LEAKING. AS I BACKED OUT, MY BRAKES WOULD NOT ENGAGE PROPERLY AGAIN AND MY CAR ROLLED BACK DOWN MY DRIVE WAY. THE CAR STOPPED AND I PARKED IT WHERE IT WAS. LATER IN THE DAY, I WAS ABLE TO PULL THE CAR INTO MY GARAGE WITHOUT INCIDENT. I TOOK THE CAR TO CHESROWN GMC (THE DEALERSHIP WHERE I PURCHASED THE VEHICLE). THEY ADVISED THEY HAD NEVER HEARD OF SUCH A SITUATION AND HAD ME BEING VEHICLE TO THEM. I COULDN'T REPLICATE THE ISSUE WITH THEM, BUT LEFT THE CAR WITH THEM SO THEY COULD CHECK IT OUT FOR ISSUES. THEY REPLACED THE THE BRAKE VACUUM PUMP. TODAY (7/31/17), THE BRAKES STARTED TO BEHAVE IN THE SAME MANNER AS WHEN THEY FAILED ON 7/16/17.
