SERVICE BRAKES
There is a recall on my 2015 GMC Yukon, that I am not the original owner of. The recall is for the brake booster and says that it expired. I have had the car checked by two different shops (both confirmed it was this), and one of them was the local GMC dealership by my house. I called to make an appointment for the recall to be fixed, to which they said they needed to order parts and it would take a few weeks. I dropped the car off three weeks later per their request for then another person to call me and say they won't fix it because it is expired. It is a safety matter that the breaks don't work occasionally.

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.

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!

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.

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.

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.

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!
