2015 GMC YUKON Service Brakes Problems

While driving in downtown boston in heavy traffic (stop and go) braking did not stop the vehicle when removing my foot from the brake and reapplying and the braking was extremely hard, the vehicle nearly collided into the vehicles in front of me. This issue persisted continously for the duration of travel. The issue was not found using the vin provided. This issue MUST be resolved ASAP. This incident was not the first, after owning the vehicle for several months this issue is a major safety issues, specifically when my new young adult drivers use this vehicle. Please help me resolve.

Trailer braking system warning is incessantly going off, without cause. Extremely distracting. No way to stop it. Truck has never even towed / trailored anything. Has happened multiple times over the last 6 months. Today occurred 26 times during driving

Loss of power steering, loss of abs, loss of cruise control, loss of forward crash assist, loss of lane departure, lose of side detection, oil leak from oil cooler line connection leaking down engine, potential fire, parking sensor, arm rest phone charger short circuit potential fire, wires pinched off at hinge point of center counsel, trailer brake system, stabilitrac, all current errors make vehicle unsafe to drive, ongoing issues since purchase including service reports of the same issues from previous owner

The brakes are hard to push to come to a stop. I brought it to a mechanic and he said it was my vacuum pump. The air bag light comes on when you hit a hard bump in the road.

While I’m parked or even driving I keep getting a alert on my speedometer ( Trailer Break System ) and it’s not a 1 time alert the whole time I’m driving it’s constantly alerting me yet I don’t even use my Trailer system at all, it’s concerning due to the distraction of trying to clear the screen constantly while I’m on the high way.

My 5 children and I experience a traumatic experience in afternoon traffic as my 2015 GMC Yukon failed to pick up speed while waiting to make a left turn at a traffic light. The vehicle - no matter how hard I pressed on the gas didn't accelerate immediately which almost cost an accident. The vehicle rode smoothly for a few minutes then out of nowhere - it started jerking and stuttering bad for 15 seconds or so then would go back to riding smooth. When pressing the brakes - it seems to "lock" to a certain extent, so I have to press really hard on the brake to slow down/stop the vehicle sometimes makes a strange noise when doing so. I took the vehicle to be accessed by a service center in my area - it was at that time that I was told that my vehicle issues are known common GMC issues in these vehicles & more unfortunately. It's unfair to be penalized with an expensive transmission repair when these issues are known to the manufacture but not the consumer - despite being "VIN specific" as told by GMC customer service. This vehicle is needed as it is utilized to transport my children however, it's unsafe at & parked in my driveway. I was directed to reach out to GMC for remedy of the identified issues.

My breaks stop working in drive through, pulling in parking spots, backing out, slow speed of traffic. I found out it's the power break vacuum pump. It then says Service brakes on my dash when it occurs. This started about 2 weeks ago.

I have owned this vehicle almost 6 years, 40,000 when purchased used. Since purchase, we have had multiple issues with the trailer brake system randomly going off, dinging non stop, we had the problem serviced under our warranty and is now going off again. We do not tow but a few times every summer which is our jet skis however. This has happened multiple times prior to us using our warranty, the garage says they fix it but it keeps happening. I am very frustrated that I can't drive my vehicle down the road without a continues dinging. I looked up what "trailer brake system" means and found that it can be very dangerous and GMC's are known to have this problem, it is suggested that I lodge a complaint in hopes of getting this problem resolved from the manufacturer before a driver becomes seriously injured when the braking system decides to fail. I have read complaint after complaint. My warranty is now expired as I recently rolled over 100,000 miles, the GMC garage told me the part was around $78 but over $400 with install, ridiculous! I have already replaced this part a little over a year ago, I went to the garage where the warranty work was performed and got all the paperwork. Why has this problem not been categorized as a recall at this point? Something isn't right!

“Service Trailer Brake System” indicator light and alert continue happening. As of this weekend, my rear driver side taillight has begun going in and out/off and on.

Brake vacuum repair. Could not stop vehicle. Brakes would get hard and vehicle kept moving.

My brakes went out and a “service” message came up and said “brake assist”

Trailer break system warning keeps appearing.

Trailer brake system service keeps displaying

" Service Trailer Brake System" 5 times a week and sometimes more than that ....on average 5 times

A message keeps popping up, “trailer brake system” it is poor wiring on GMC part. I did research on this and looked it up and other people had similar issues which can be very severe if driver continues to use after this message pops up. The message is so continuous that it could distract the driver, which could lead to a fatal accident.

While I was in line at the gas station to get gas, I moved up because the car I front of me had done so. After moving up a bit, I pressed my feet on the brake but the pedal was very stiff and the breaks did not hardly engage. I almost ran into the vehicle in front of me. This was very scary. So I called for a tow truck to pick me up but after a while they didn’t show. I started my car up to see if the the brakes engaged and they did. So I slowly and carefully drove myself to the GMC dealership in Southaven, MC which was 0.3 mile away from the gas station. The GMC dealership said that it was vacuum pump that was at fault and admitted it was a recall for this. But they said since my truck has already been serviced for this recall that I would have to pay to get it fixed. This is absolutely absurd. If the issue was not fixed properly in the first place, why would I be responsible for getting it fixed the second time?

Last week, the power brake assist began fading away intermittently at low speeds, and caught my wife off guard in a grocery store parking lot when she pulled into a parking space and the brakes were not available. She had to plant both feet on the brake pedal in a panic stop before crashing into the car parked in front of her, and has since never driven the vehicle. This is a danger, and is potentially life threatening.

I almost died today. My brakes failed pedal went hard still is. Had to drive home with a stiff pedal and almost no brakes. Just paid $50,000 for this truck

Brakes are not stopping the vehicle on short distances as it should. They are doing a clicking kind of noise and can feel pulses in the brake pedal as though ABS are trying to activate. I know there is a recall out but is saying my 2015 is not listed yet is doing the same thing that is described in the recall.

Drivers side tail light intermittently works, doesn't work all the time. Passenger side brake light stays on continuously, never changes.

FIRST NOTE THAT OUR RECALL FOR INCREASED PEDAL EFFORT WAS DONE ON OUR 2015 GMC YUKON 2 MONTHS BEFORE THIS INCIDENT. OUR VEHICLE WAS TRAVELING AT A HIGH RATE OF SPEED COMING HOME FROM MAMMOTH ON THE 15 FREEWAY. WE HEARD WHAT WE DESCRIBE AS A 'BUZZING' NOISE BUT WE COULDN'T TELL IF IT WAS OUR CAR OR ANOTHER ON THE FREEWAY IT ALMOST SOUNDED LIKE TIRE TREAD BEFORE YOU HAVE A BLOW OUT. WE SLOWED DOWN A BIT (65-70MPH) TO CHECK OUR SURROUNDINGS. A FEW MINUTES LATER WE STARTED TO LOSE CONTROL OF OUR YUKON. I STARTED TO UNBUCKLE AND CLIMB TO MY HUSBANDS DRIVERS SEAT BECAUSE HE WASN'T RESPONDING TO OUR SCREAMS AND HE LOOKED ILL. AS I WAS SCREAMING HIS NAME HE FINALLY SAYS INTO MY EAR WE HAVE TO CRASH! I PANICKED AND SCREAMED WHAT IS HAPPENING. HE REPLIES 'WE HAVE NO BRAKES'! THE PEDAL WAS AS HARD AS A ROCK LIKE A BRICK WAS UNDERNEATH IT AND OUR CAR WAS SERVING BACK AND FORTH. AS TRAFFIC SLOWED AND WE PREPARED TO CRASH INTO THE CAR IN FRONT THE CENTER DIVIDER OPENED UP AND WE WERE ABLE TO CRUISE DOWN IT UNTIL WE SLAMMED E BRAKE ON. THESE MODELS SHOULD NOT BE ON THE ROAD AND WE COULD HAVE VERY EASILY DIED OR KILLED ANOTHER FAMILY IN THE PROCESS! ABSOLUTELY UNACCEPTABLE ON GMS PART! TERRIFYING! THERE HAS BEEN NO VACUUM PUMP RECALL PLACED ON OUR YUKON AND IT WAS THE VACUUM PUMP THAT FAILED WHICH MADE THE BRAKES FAIL THERE WAS NO BACK UP ZERO BRAKES WITH A FAMILY OF 5 IN THE CAR ON THE FREEWAY! EVERY OWNER WHO OWNS A 2015/2016 SHOULD BE AWARE THAT THIS CAN HAPPEN TO THEM. IT'S NOT JUST AT SLOW SPEED. WE HAVEN'T STEPPED FOOT IN OUR CAR SINCE OUR KIDS ARE SCARED TO DEATH TO RIDE IN ANY CAR THAT LOOKS LIKE IT.

THERE WAS A RECALL FOR LOW BREAK FAILURE IT WAS RECALL 19V645. I HAD THIS DONE LAST YEAR AND TODAY I ALMOST HIT A CAR IN THE DRIVE THROUGH SIDE THE BRAKES ARE STILL DOING THE SAME THING GOING TO THE FLOOR. THEY NEED TO REPLACE THE FAULTY VACUUM PUMP. I EXPERIENCE THIS WHILE BACKING OUT AND STOPPING AT SLOW SPEEDS.

I BOUGHT MY GMC YUKON IN MARCH OF 2019 ABOUT A WEEK LATER I HAD PEOPLE INFORM ME MY BRAKE LIGHTS WERE NOT WORKING. I WOULD CHECK AT NIGHT AND THEY WOULD. A FEW MONTHS LATER I NOTICED IT MYSELF, THEY WOULD WORK ONE MINUTE BUT NOT THE NEXT. DECEMBER OF 2019 I GET A LETTER FROM GMC STATING THEY KNOW 2015 MODEL GMC YUKON VEHICLES MAY HAVE A CONDITION WHERE THE BRAKE LIGHTS INTERMITTENTLY DO NOT ILLUMINATE. I COULD HAVE IT DONE IF MY SUV WAS NOT OVER 72K MILES BUT IT WAS WHEN I BOUGHT IT. SO THAT DOESN'T HELP ME AND THEY WANT $2K TO FIX IT. I CALLED TO SEE WHAT THEY COULD DO AND THEY TOLD ME THIS WASN'T A SAFETY ISSUE. IF THEY DO WORK AND SOMEONE DOESN'T SEE I AM BRAKING, MY KIDS OR FAMILY ARE IN THE BACK SEAT, HOW IS THAT NOT SAFETY RELATED? THEY NEED TO MAKE THIS A RECALL! *TR

TAIL LAMPS, TAIL LAMPS TAIL LAMPS! NON SERVICEABLE LED ILLUMINATION BULB CIRCUIT IS FAULTY LEADING TO INTERMITTENT OPERATION. HAVING PART TIME BRAKE LIGHT IS AGAINST THE LAW AND MORE IMPORTANT TO ME, LEAVES MY FAMILY IN AN UNSAFE SITUATION. WEB SEARCH LEADS TO MANY MOTORIST HAVING THE SAME PROBLEM AS I.

WHEN TRAVELING AT LOW SPEEDS, LESS THAN 5 MPH, THE BRAKE PEDAL WILL BECOME HARD TO PUSH AND CAR WILL NOT COME TO A COMPLETE STOP, BUT WILL ROLL TO A STOP. THIS CAN HAPPEN TRYING TO PULL INTO A TIGHT SPOT OR WHILE IN A DRIVE-THRU OR IN STOP AND GO TRAFFIC OR SIMPLY YOUR OWN GARAGE OR BACKING OUT OF A DRIVEWAY OR FOUR WAY STOP, THE LIST CAN GO ON AND ON. IT HAPPENS ON A DAILY BASIS. I TOOK TO THE CERTIFIED DEALER TO HAVE THE RECALL PERFORMED BUT APPARENTLY THE RECALL WILL NOT WORK ON MY VEHICLE AS THE VACUUM PUMP NEEDS TO BE REPLACED. WHEN IT FIRST HAPPENED WAS OCT 2018 AND HAD ABOUT 80K MILES ON IT. IT CONTINUES TO HAPPEN AND NEEDS TO BE FIXED. IT IS A 2015 YUKON AND SHOULD NOT BE HAVING THIS TYPE OF PROBLEM. IT IS RIDICULOUS THAT GMC IS AWARE OF THE PROBLEM BUT WANTS TO NOT RECALL FOR THE PART TO BE REPLACED BUT HAVE ANYONE HAVING THE PROBLEM COME IN AND SEE IF THE SOFTWARE UPDATE WILL TAKE CARE OF THE PROBLEM. THEN AT THAT TIME LETS CHARGE THE CUSTOMER WELL OVER $600 TO HAVE THE PUMP REPLACED INSTEAD OF MAKING IT RIGHT BY THE CUSTOMERS. I WILL BE TAKING MY CAR ELSE WHERE TO HAVE THE PART REPLACED FOR HALF THE COST TO ME. THIS HAS BEEN A WASTE OF TIME AND I COULD HAD TAKEN ELSE WHERE TO BEGIN WITH MONTHS AGO, IF I WOULD HAD KNOWN THE TYPE OF RECALL THAT GMC WOULD BE GIVING. WHEN YOU PAY MORE THAN $60K FOR A VEHICLE THESE TYPE OF PROBLEMS SHOULD NOT HAPPEN.

WHILE TRAVELING ON A HIGHWAY TO WORK-RELATED CAMP, UPON ARRIVAL, CO-WORKERS INFORMED ME ONE OF MY BRAKE LIGHTS WAS OUT. BRAKELIGHT WORKED SPORADICALLY BEFORE COMPLETELY GOING OUT FOR ABOUT 2 WEEKS FINALLY BEING ABLE TO SHOW SERVICE DEPARTMENT. RESEARCHED CARGURUS AND NUMEROUS PEOPLE REPORTED THE CIRCUIT CRACKS AND EVENTUALLY BURNS OUT. DESIGN FLAW WHICH TURNS INTO A SAFETY ISSUE!!! RECALL IS NEEDED!!!

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

Mileage: 70,000

REAR BRAKE LIGHT ASSEMBLY FAILING TO LIGHT WHEN BRAKES APPLIED AND THERE IS NOT A NOTIFICATION TO THE DRIVER. THIS IS A MANUFACTURE FLAW WITH THE LED LIGHT CIRCUIT INSIDE THE ASSEMBLY. THERE IS NOT A LIGHT OUT NOTIFICATION SO THE DRIVER IS NOT AWARE THE BRAKE LIGHT HAS FAILED. THIS IS A SAFETY ISSUE AND IS AN WELL KNOWN ISSUE ON THE 2015-2019 YUKON. THIS IS OCCURRING OFTEN AND GMC IS HAVING PROBLEMS WITH SUPPLYING REPLACEMENTS BECAUSE THE DEMAND IS SO HIGH FROM THE FAILURE. GMC HAS ALSO RAISED THE PRICE OF THE BRAKE LIGHT BY 30% FROM $425 TO $675 NOT INCLUDING LABOR. I CALLED THE DEALER AND THEY INFORMED IT WAS A HIGH FAILING ITEM AND WAS ON BACKORDER AND NOT SURE WHEN THEY WOULD GET ONE. DRIVING THE VEHICLE WITHOUT PROPER BRAKE LIGHTS IS A SAFETY CONCERN AND NOT LEGAL SO LEFT WITH LITTLE OPTION BUT TO STOP DRIVING THE YUKON.

Mileage: 60,000

WHILE SITTING STILL AT A DRIVE THROUGH, BRAKE PEDAL WENT TO FLOOR AS IF IT HAD NO PRESSURE. HAD NO BRAKES! NO MATTER HOW HARD I STOOD ON PEDAL THE CAR WOULD NOT COME TO COMPLETE STOP WHEN ROLLING. BLEW THROUGH STOP SIGNS AND LIGHTS BECAUSE EVEN AT 10 MPH COULD NOT STOP VEHICLE FROM ROLLING. HAD JUST GOT OFF INTERSTATE DOING 70 MPH. DOWN HILL GRADE WAS IMPOSSIBLE. FOUND OUT THAT THIS WAS A KNOWN ISSUE BY GM INVOLVING FAILURE OF VACUUM PUMP BOOSTER. MANY REPORTS, HOPEFULLY NOT MANY DEATHS CAUSED.

Mileage: 36,000

BOTH BRAKE LIGHTS WORK INTERMITTENTLY. IF YOU TAP HARD ON IT THEY SOMETIMES COME BACK ON BUT DON'T STAY ON. I TOOK TO GMC DEALER WHERE THEY INFORMED ME THEY'VE HAD A DOZEN YUKON'S IN RECENTLY WITH THE SAME ISSUE. DEALER INDICATED ISSUE IS FAULTY CIRCUIT BOARD THAT OVERHEATS CAUSING THE LIGHTS TO SHORT OUT. I'M OUT OF MANUFACTURERS WARRANTY. EXTENDED WARRANTY DOES NOT COVER LIGHTS. DEALER CHARGES $800 PER LIGHT (PART ONLY).

Mileage: 48,000

BRAKES DON'T WORK WELL WHEN TRAVELING AT LOW RATES OF SPEED. STOPPING REQUIRES BRAKES TO BE PRESSED TO THE GROUND AND STILL MAY NOT STOP. I HAVE ALMOST HAD SEVERAL ACCIDENTS EVEN AFTER HAVING THE ISSUE 'REPAIRED' LAST YEAR. I'VE HAD THE PROBLEM ASSESSED AT 3 DIFFERENT MECHANICS. I HAVE HAD TO THROW MY CAR INTO PARK TO AVOID HITTING CARS IN FRONT OF ME. BRAKES FAIL WHILE DRIVING IN PLACES SUCH AS TRAFFIC JAMS, DRIVE THRU, SCHOOL PICK UP, ETC. THIS IS A HUGE SAFETY HAZARD AND FEAR THAT MY CHILDREN MAY BE HURT IF THIS ISSUE IS NOT CORRECTED BY THE MANUFACTURER. STEERING BECOMES NEARLY IMPOSSIBLE WHEN THE BRAKE ISSUES OCCUR. THIS IS AN ONGOING PROBLEM FOR THE LAST 1.5- 2 YEARS. ALSO, THE TAIL LIGHTS CONTINUE TO GO OUT EVEN AFTER PAYING HUNDREDS OF DOLLARS FOR REPLACEMENTS.

Mileage: 70,000

VERY HARD/ STIFF BRAKE-PEDAL. IT'S VERY HARD TO STOP THE VEHICLE AT ANY SPEED. I ALREADY REPLACED THE BRAKE PADS AND THE PROBLEM STILL CONTINUES, IS A VERY DANGEROUS HAZARDS TO THE DRIVE THE VEHICLE IN THAT CONDITION. THE HARD /STIFF PEDESTAL IS IN THE CITY AND THE HIGHWAY.

TAIL/BRAKE LIGHTS FAILED CAUSING A SAFETY CONCERN. TOOK VEHICLE IN TO GMC DEALER FOR REPAIR. LEFT TAIL LIGHT (ACTUALLY THE ENTIRE PRINTED CIRCUIT BOARD) WAS REPLACED, RIGHT IS ON BACK ORDER. VEHICLE OUT OF FACTORY WARRANTY AND EVEN THOUGH WE HAD AN EXTENDED BUMPER TO BUMPER WARRANTY, THE WORK WAS NOT COVERED. THIS IS A FREQUENT ISSUE, I HAVE DISCOVERED ON LINE, ACCORDING TO MANY OWNERS OF GMC SUVS AND TRUCKS BETWEEN THE 2015 AND 2018 MODELS. COST OF REPAIR INCLUDING BOTH TAIL LIGHTS IS 1617.05. GMC SUPPORTED ME BY COVERING 600.00 OF THE COST SO I PAID 1017.05 OUT OF POCKET FOR 2 TAIL LIGHTS THAT SHOULD NOT HAVE FAILED. I HAVE ONLY 24554 MILES ON THE VEHICLE AND HAVE NEVER HAD AN ACCIDENT. ADDITIONAL TO THAT, THE 2 FRONT SEAT BELTS ARE FRAYING WHICH MAY LEAD TO WEAKNESS EVENTUALLY CAUSING A SAFETY ISSUE. I WANT GMC TO COVER ALL COSTS RELATED TO REPAIR OF THESE TWO PROBLEMS. THERE SHOULD BE A RECALL REGARDING BOTH. SEAT BELT PROBLEM HAS BEEN ON GOING FOR MONTHS AND THE TAIL LIGHT THING JUST HAPPENED ON MONDAY, JUNE 17, 2019.

THE MOST DISTURBING CONCERN IS THE FACT THAT I LOST MY BRAKES AS A RESULT OF A KNOWN PROBLEM THAT GM HAS EVEN RECOGNIZED RELATING TO A FAULTY VACUUM BOOSTER PUMP. I INCURRED A $500 REPAIR BILL DESPITE GM'S ACKNOWLEDGEMENT OF THE PROBLEM AND WILLINGNESS TO PAY FOR CARS WITH LESS THAN 70000 MILES. UNFORTUNATELY, MINE WAS OVER THE ALLOWABLE MILEAGE. ADDITIONALLY, I AM LOOKING AT A $1500 REPAIR BILL FOR A SEALED HEADLIGHT REPLACEMENT AND ANOTHER $300 BILL FOR A SIDE DETECTION SYSTEM ( LANE DEPARTURE WARNING). GM MADE A POOR CAR THAT IS UNSAFE AND IS NOT PROPERLY ADDRESSING THE PROBLEM.

BRAKES BECOME HARD TO PUSH WHEN GOING BELOW 5MPH AND DOESN'T WANT TO STOP WHEN PRESSED. SOMETIMES YOU PRESS BRAKES AND PUSH AS HARD AS YOU CAN AND IT JUST KEEPS MOVING UNTIL HE SLOWLY COMES TO A STOP. IT HAPPENS WHEN TRAVELING AT A LOW SPEED OR EVEN AT A STOP AND YOU NEED TO BARELY MOVE FORWARD OR BACKWARD. MAKES IT HARD TO PARK IN TIGHT SPACES, MOVE IN TRAFFIC, AND IN A DRIVE-THRU. IT WILL HAPPEN MOVING FORWARD OR BACKWARD - THAT DOESN'T MATTER IT ALSO HAPPENS WHEN YOU COME TO A STOP AND BARELY MOVE AGAIN AND NEED TO STOP - BRAKES BECOME HARD AND IT STOPS ON ITS OWN TIME. I EVEN HAD IT HAPPEN WHEN I WAS AT A STOP LIGHT ON DOWNWARD HILL AND THE CAR IN FRONT OF ME STARTED MOVING AND SUDDENLY STOPPED AGAIN AND MY CAR DIDN'T WANT TO STOP.

BRAKING BECOMES "HARD" AFTER BRAKING WHILE MOVING (E.G. IN RUSH HOUR TRAFFIC OR SLOWLY GOING DOWN A HILL).THIS STARTED WHILE GOING DOWNHILL IN AN ANIMAL RESERVE. I WAS INCHING FORWARD TO GET BETTER VIEWS OF THE ANIMALS. HALFWAY DOWN THE HILL THE BRAKES COMPLETELY FAILED. I HAD TO LITERALLY STAND UP ON THE BRAKE, AND IT STILL WOULDN'T STOP THE CAR. AFTER TAKING MY FOOT OFF THE BRAKE FOR A BIT, THE PROBLEM FIXED ITSELF. WHEN I TOOK IT TO THE DEALER, THEY SAID IT WAS A FAULTY VACUUM PUMP ($500 REPAIR), BUT ONLINE RESEARCH SAYS REPLACING THE VACUUM PUMP DOESN'T SOLVE THE PROBLEM. NOTE, THIS PROBLEM CONTINUES TO PERSIST.

ON TWO SEPARATE OCCASIONS WHEN PARKING, AND DRIVING AT A HIGH RATE OF SOEEDV( 60 MPH)ON INTERSTATE IN SUDDEN STOP AND GO TRAFFIC BRAKES FAILED TO ENGAGE AFTER WORKING PROPERLY BEFORE AND AGAIN AFTER WITH MORE THAN A MONTH BETWEEN INCIDENTS . THE SECOND INCIDENT OCCURRED ON 12/31/18 AFTER THE VEHICLE HAD BEEN IN FOR ROUTINE OIL CHANGE AND SERVICE THAT INCLUDED A MULTI POINT INSPECTION AT THE GMC DEALERSHIP WHERE IT WAS PURCHASED BRAND NEW. THE VEHICLE IS FREQUENTLY SERVICED AS REQUIRED AND HAS TIRES WITH GOOD TREAD . THE FAILURE IS ALARMING AS IT OFTEN COMES WHEN TRYING TO MAKE A NECESSARY STOP AND THE FAILURE COMES OUT OF THE BLUE THEN RETURNS TO NORMAL.

POWER BRAKES FAILING AT LOW SPEEDS-IN FREEWAY TRAFFIC-PULLING INTO DRIVEWAY REQUIRES STRONG PRESSING ON BRAKE PEDAL AS IF THE BRAKES ARE INTERMITTENTLY LOOSING POWER ASSIST

Mileage: 94,000

AT SLOW SPEED IN STOP AND GO TRAFFIC THE BRAKES WILL WORK ONE TIME AND THE NEXT TIME I WOULD HAVE TO STOMP THE BRAKE PEDAL TO GET THE SUV TO STOP IT WAS ON A STREET WHEN IT HAPPENED I HAVE TRIED TO CONTACT FLOW GMC OF WINSTON-SALEM MULTIPLE TIMES AND CAN'T GET ANYONE TO TALK TO ME

Mileage: 60,000

ON MULTIPLE OCCASIONS SPECIFICALLY WHILE TRAVELING AT LOW SPEED RATE SUCH AS SLOW MOVING TRAFFIC OR PULLING IN OR BACKING OUT OF PARKING SPACE. THE BRAKES BECOME HARD TO PUSH AND THE BRAKES DO NOT ENGAGE. YOU MUST PUSH THE BRAKES VERY HARD TO STOP. WE TOOK TO THE GM SERVICE AT OUR DEALERSHIP AND A BRAKE VACUUM PUMP WAS REPLACED. THE NEXT DAY WE WERE DRIVING THE VEHICLE AND THE BRAKES FAILED TO STOP. THANKFULLY WE WERE IN A PARKING LOT AND WERE ABLE TO STOP AGAINST BUMPER STOP. WE CALLED THE GM SERVICE DEALERSHIP AND THEY ARRANGED FOR A TOW. THIS IS EXTREMELY DANGEROUS SITUATION.

Mileage: 100,000

AT SLOWER SPEED, BRAKES BECOME STIFF AND WAS UNABLE TO STOP VEHICLE. THE BRAKES DID NOT ENGAGE ALL THE WAY TO THE FLOOR AS NORMAL AND INSTEAD STOPPED ABOUT 1/4 OF THE WAY AND WAS SOLID EVEN WHEN PRESSING BOTH FEET ON THE BRAKE. ALMOST REAR-ENDED THE VEHICLE IN FRONT OF ME BUT SINCE I WAS AT SUCH A SLOW RATE OF SPEED I WAS ABLE TO ROLL A FEW FEET AND THE VEHICLE STOPPED. I HAD TO TURN THE VEHICLE COMPLETELY OFF AND START IT BACK UP AND IT SEEMED TO WORK FINE BUT THE NEXT TIME I WAS IN THE VEHICLE AT THE SLOW RATE OF SPEED, THE BRAKES THEN AGAIN WERE VERY HARD TO PRESS. I DO NOT FEEL COMFORTABLE DRIVING THE VEHICLE UNTIL THIS PROBLEM IS TAKEN CARE OF. I CONTACTED THE LOCAL DEALER AND THEY TOLD ME IT WOULD BE 5 DAYS UNTIL THEY COULD GET TO IT - DISAPPOINTED IN THAT CONSIDERING THE SEVERITY OF THE ISSUE.

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING AT LOW SPEEDS, THE BRAKES FAILED TO ENGAGE. THE BRAKE PEDAL BECAME EXTREMELY STIFF AND THE EMERGENCY BRAKE HAD TO BE APPLIED TO STOP THE VEHICLE. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOTIFIED AND REFERRED THE CONTACT TO NHTSA. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 47,200.

WHEN DRIVING IN STOP AND GO TRAFFIC OR CITY DRIVING THE BRAKE PEDAL WILL BECOME HARD TO PUSH AND LITTLE TO NO BRAKING POWER. BRAKES ARE FINE AT HIGH WAY SPEEDS.

Mileage: 92,000

DRIVING AT A LOW SPEED THROUGH A DRIVE THROUGH AND MY BRAKES FAILED WHEN I TRIED TO STOP BEFORE PULLING OUT ONTO A CROSS STREET. PEDAL LOCKED, AND VEHICLE CONTINUED TO ROLL. AFTER STEPPING ON THE BRAKES A FEW TIMES THEY ENGAGED AGAIN. SAME PROBLEM HAPPENED AGAIN WHEN I WAS LEAVING A PARKING LOT, ONLY THIS TIME THE BRAKES WOULD NOT ENGAGE AFTER SEVERAL ATTEMPTS. I COASTED INTO A POTTED DECORATIVE TREE THAT STOPPED ME, SHIFTED INTO NEUTRAL AND BACK INTO DRIVE AND THEY BEGAN WORKING AGAIN. NO WARNING SIGNALS APPEARED ON DASH, AND BRAKES AND BRAKE FLUID HAVE BEEN CHECKED AND ALL ARE SATISFACTORY.

Mileage: 57,000

THE PASSENGER TAIL LIGHT IS WORKING INTERMITTENTLY. THE DEALER SAID THAT THE ONLY FIX IS TO BUY A NEW BRAKE LIGHT UNIT @ $650. AFTER SEARCHING ON LINE, OTHER OPTIONS ARE TO SEND BRAKE LIGHT UNIT OFF FOR REPAIR, OR PURCHASE AFTER MARKET BRAKE LIGHT UNIT. AS MANY PEOPLE THAT ARE HAVING THIS SAME ISSUE, IT SURE SEEMS LIKE GMC WOULD CORRECT THIS FAULTY BRAKE LIGHT.

Mileage: 70,000

BRAKE PEDAL SUDDENLY GOT ROCK HARD WHEN I WAS TRYING TO SLOW DOWN, OUR TRUCK JUST KEPT GOING FORWARD, I WAS HELPLESS IN THAT SITUATION AND REALLY THOUGHT THAT ACCIDENT IS UNAVOIDABLE BECAUSE I WAS GETTING CLOSER AND CLOSER TO ANOTHER VEHICLE, AFTER PRESSING BRAKE PEDAL MANY MORE TIMES I WAS ABLE TO STOP OUR YUKON LITERALLY ONE INCH FROM A CAR IN FRONT OF ME

Mileage: 42,500

I WAS TOLD MY A COLLEGUE THAT MY DRIVERS SIDE BRAKE LIGHT WAS OUT. I TOOK IT INTO THE LOCAL MECHANIC AND IT WAS NOT OUT. A FEW MONTHS GO BY AND I AM TOLD AGAIN, THAT MY DRIVERS SIDE TAIL LIGHT IS OUT. I TAKE IT TO A DIFFERENT SHOP AND IT IS WORKING CORRECTLY. THE VERY NEXT DAY A TRUCK TELLS ME AT A STOP LIGHT THAT I HAVE NO BRAKE LIGHTS. I WAS PULLED OVER BY A POLICE OFFICER FOR NOT HAVING PROPERLY WORKING BREAK LIGHTS. HE LET'S ME GO WITH A FRIENDLY NOTICE, BUT AS SOON AS I STARTED MY VEHICLE TO DRIVE AWAY HE IMMEDIATELY PULLS ME BACK OVER TO TELL ME THAT HE WAS MISTAKEN THAT ONLY MY DRIERS SIDE BRAKE LIGHT WAS OUT. THIS HAS HAPPENED INTERMITTENTLY OVER THE LAST THREE TO FOUR MONTHS.

I WAS DRIVING AND WITH WARNING SUV STARTED ACCELERATING AND I BRAKES WOOD NOT WORK I WAS NOT ABLE TO STOP INTILL I PRESS HARD ON THE PEDAL

DRIVER SIDE BRAKE LED LIGHTING IS WORKING INTERMITTENTLY. HAD IT REPLACED UNDER WARRANTY. PASSENGER SIDE BRAKE LED LIGHTING NOW WORKING INTERMITTENTLY, NEW ISSUE. HAVE NOT HAD REPLACED YET DUE TO OUTRAGEOUS COST($700) FOR FIXTURE REPLACEMENT. ONLY 40,000 MILES ON VEHICLE OBVIOUSLY REFLECTS A SERIOUS SAFETY ISSUE TO FINANCIALLY STRAPPED CONSUMERS.

Mileage: 40,000

REAR LEFT AND RIGHT BRAKE LIGHTS STOPPED WORKING WITH NO WARNING WHILE AT A STOP LIGHT IN THE CITY. APPARENTLY SEVERAL GMC YUKON 2015 OWNERS ARE HAVING THE SAME PROBLEM AND IT'S AN ELECTRICAL DEFECT WITH THE TAILLIGHTS IT'S NOT THE BULBS.

Mileage: 48,760

THE PASSENGER SIDE BRAKE LIGHT ON MY 2015 GMC YUKON NO LONGER WORKS. THE COST TO REPLACE IT IS OVER $500. AFTER DOING SOME RESEARCH ON LED LIGHTS I BELIEVE THE BRAKE LIGHT IS FAULTY OR CHEAPLY MADE AND THAT IT SHOULD LAST A LOT LONGER THAN 3 YEARS AND 66,000 MILES.

Mileage: 66,254

BOTH BRAKE LIGHTS FAILED WITHIN WEEKS OF EACH OTHER - AROUND 60K MILES. FAULTY LED CIRCUIT BOARDS. LIGHT ASSEMBLIES ARE NOT REPAIRABLE BY DEALERSHIP. NEW ASSEMBLY OVER $500 EACH. GM TAKES NO RESPONSIBILITY IN RESOLVING THE ISSUE. UNACCEPTABLE! NO MORE GMS FOR MY FAMILY! .. AND THAT INCLUDES CHEVY.

EARLIER THIS YEAR I PURCHASED A 2015 GMC YUKON DENALI. AFTER DRIVING IT A SHORT AMOUNT OF TIME I REALIZED THE BRAKE PEDAL IS LOCATED SIGNIFICANTLY HIGHER THAN THE GAS PEDAL. I'VE COME TO REALIZE THAT THE ~4INCH GAP IS CAUSING A SEVERE SAFETY HAZARD, ESPECIALLY IN EMERGENCY BRAKING SITUATIONS. MY FOOT, ALONG WITH OTHERS IN THE POST LINKED BELOW, OFTEN GETS CAUGHT IN THE LARGE GAP BETWEEN THE GAS AND THE BRAKE, ESPECIALLY WHEN MOVING QUICKLY. THERE HAVE BEEN MANY INSTANCES TO DATE WHERE THE SOLE OF MY SHOES HAS GOTTEN STUCK UNDER THE BRAKE PEDAL, PREVENTING ME FROM STOPPING IN TIME. I'VE NARROWLY AVOIDED AT LEAST 5 ACCIDENTS, BECAUSE OF THIS. FEARING THAT IT IS A MATTER OF TIME BEFORE IT RESULTS IN A COLLISION I REACHED OUT TO GMC TO SEE IF THERE WAS A FIX. THEY RESPONDED AND SAID THAT THE PEDALS ARE WORKING AS DESIGNED AND SAID THERE WAS NOTHING THAT CAN BE DONE. I'M VERY DISAPPOINTED IN THEIR RESPONSE, ESPECIALLY CONSIDERING THE CLEAR SAFETY HAZARD IT CREATES. IT IS A LARGE CAR, REQUIRING MORE BRAKING DISTANCE THAN MOST. ANY IMPEDANCE TO THE PROCESS SHOULD BE TAKEN SERIOUSLY ESPECIALLY IF IT IS A MANUFACTURER DESIGN FLAW SUCH AS THIS. SIMILAR COMPLAINTS HAVE BEEN VOICED IN THIS ONLINE CONSUMER THREAD. ONE OF MANY THAT I FOUND REITERATING THE PROBLEM. HTTP://WWW.TAHOEYUKONFORUM.COM/THREADS/GAS-BRAKE-PEDAL-DISTANCE.67500/

I JUST COMPLETED A CLAIM FOR MY 2015 YUKON DENALI, NHTSA ID #: 10643049 AND READ THAT ALMOST THE SAME EXACT ISSUES ARE GOING ON WITH THE 2015 CHEVY TAHOE MODELS, SEE: NHTSA ID NUMBER: 10638437, 10633519 AND 10631583. WHEN WILL GM SEE THERE IS A PATTERN AND ISSUE A RECALL FOR THIS TRANSMISSION ISSUE? IN ALL CASES THESE RENDER THE CALLS UN-DRIVABLE AND HAVING TO HAVE THEM TOWED. *TR

Mileage: 500

I HAVE A BRAND NEW 2015 YUKON DENALI (SHORT WHEEL BASE) WITH LESS THAN A THOUSAND MILES AND A "SERVICE 4WD" MESSAGE THAT HAS APPEARED TWICE RENDERING THE CAR EXTREMELY UNSAFE AND UN-DRIVABLE FOR A LONG DISTANCE AND HAVING TO HAVE IT TOWED TO THE DEALER TWICE. A SOFTWARE UPDATE WAS DONE ON THE CAR THE FIRST TIME, ONLY RESOLVED THE ISSUE FOR A FEW WEEKS, THE ISSUE RE-OCCURRED AFTER 3 WEEKS. WHEN TURNING THE VEHICLE ON THE DASH GIVES THE MESSAGE "SERVICE 4WD". THE CAR HAS A TRANSMISSION BUTTON TO CHANGE FROM 2WD, AUTO, 4 HIGH AND 4 LOW. I DO NOT TOUCH THIS BUTTON, I JUST LEAVE THE CAR IN AUTO AND DRIVE. I DO NOT TOW ANYTHING, THIS IS JUST A FAMILY CAR USED FOR COMMUTING. WHEN THE "SERVICE 4WD' MESSAGE APPEARS, THE CAR IS BARELY DRIVABLE. WHEN IT IS PUT IN REVERSE, THE CAR JUST BRAKES AFTER A FEW FEET, AS IF THE PARKING BRAKE WERE ON, BUT IT OBVIOUS IS NOT ENGAGED. WHEN TURNING LEFT OR RIGHT, THE CAR BRAKES MID-TURN AND WILL ONLY COMPLETE THE TURN IF 3/4 TO FULL ACCELERATOR IS APPLIED TO CONTINUE THROUGH THE TURN. THE CAR SLIGHTLY BUCKS THROUGH THE TURN AND THE ENGINE SOUNDS DIFFERENT AND HAS LITTLE POWER GOING AROUND CORNERS AND GOING UP HILLS. THE CAR CANNOT SAFELY BE DRIVEN IN A STRAIGHT LINE FASTER THAN 40-50 MPH. I TELEPHONED ONSTAR AND DIAGNOSTICS WERE RUN DURING BOTH OCCURRENCES WITH THE SAME ERROR MESSAGE FROM ONSTAR DIAGNOSTICS: "THE BRAKING SYSTEM HAS AN ISSUE- TRANSFER CASE MODULE NOT WORKING AS EXPECTED". WHEN WILL GM ISSUE A RECALL ON THIS SAFETY ISSUE, I DO NOT FEEL SAFE LETTING MY WIFE AND CHILD IN THE CAR IF IT BRAKES BY ITSELF, LOSES POWER AND CANNOT COMPLETE TURNS. I PURCHASED THIS CAR TO HAVE A SAFE/LARGE VEHICLE FOR MY FAMILY: SERVICE 4WD APPEARS ON SCREEN IT RENDERS THE CAR UN-DRIVABLE AND THE TRANSMISSION BUTTON BECOMES INOPERABLE AND SELECTING OTHER TRANSMISSION MODES BECOMES NOT POSSIBLE. *TR
