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.
2015 GMC Yukon brakes complaints
Page 2 of 4: complaints 11 to 40 of 90, newest first, as owners wrote them.
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?
The contact owns a 2015 GMC Yukon. The contact stated while driving 40 MPH, he had to depress the brake pedal with extra force to stop the vehicle. The contact stated that the brake assist warning light was illuminated. The contact was able to continue to drive to his destination. The contact took the vehicle to an independent mechanic, where the repair was being performed. The contact called the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 73,000.
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!
The tail lights stop working or they flicker like there's a loose connection or something not making contact I e seen other complaints about the same thing and gm now has a new improved tail light but the old ones all fail all stop working . On the braking system it doesn't brake when going a low speed without giving it gas I have to pump n push the brakes all the way down or give it a lil gas to be able to stop or brake the lights flicker or stop working while driving stop all the time the dealer wants 1500-2000 to replace em the lights.. They are defective and should be recalled their bad workmanship shouldn't be mine our anybody else that has this vehicle burden this is not a cheap vehicle I paid over $50,000 used for about a year.. I need your help. The brakes need to be fixed also because at low speeds with no gas on the pedal I can roll into something hit something or someone.
Tl* the contact owns a 2015 gmc yukon. The contact stated that the brake light failed to illuminate when the brake pedal was depressed. The contact received a customer satisfaction program regarding the brake light. The contact was informed that the vehicle was included in the federal safety agency campaign numbers: 18v586000 (steering) and 19v645000 (service brakes, hydraulic). Stanley wood chevrolet buick gmc (1674 batesville blvd, batesville, ar 72501, (870) 390-4093) was contacted and an appointment was scheduled to have the vehicle repaired under the recalls. The contact was also informed that the mileage was exceeded under the customer satisfaction program. The manufacturer was notified of the failure. The approximate failure mileage was 113,000.
Tl* the contact owns a 2015 gmc yukon. The contact received notification of the federal safety agency campaign number: 19v761000 (service brakes, hydraulic, service brakes, electronic stability control). The vehicle was taken to the keller motors located at (700 cadillac ln, hanford, ca 93230) where the computer was reprogrammed. The contact stated that after the reprogramming, the brake lights started to work intermittently. The vehicle also stalled with several warning lights illuminated on the instrument panel. The contact stated that the seatbelt unbuckled and open or close driver's window warning lights were illuminated. The contact was informed by the dealer that the reprogramming was not the cause of the failures. The vehicle was not repaired. The manufacturer was not made aware of the failures. The failure mileage was approximately 61,000.
Upon pressing the brakes while parking, pedal started vibrating and brake pedal became impossible to press. Pedal continues to remain hard to press for braking.
Tail lamps would intermittently operate. At times none would work at others some would work. And others all would work. Gmc finally addresses this with: n182180270 (special coverage). Gmc was aware of this issue on or prior to november 26, 2019. They stated notifications to customers would begin on december 12, 2019. I was notified today 2-12-2020 well after gmc was aware of issues. Gmc allows for warranty of 6 years after placed in service or 72,000 miles. Since my vehicle had 902 miles at time of purchase my warranty expired at 72,902 miles. Had gmc made me aware in december or too after knowing in late nov 2019 I would still have been under warranty for a resolution to fix issues. There willful negligence in failing to notify me hindered their available warranty under special coverage of no use to me to my detriment of several hundred dollars (~$1800 usd).
2015 gmc yukon. Consumer writes seeking reimbursement for vehicle repairs related to safety recall. *ld

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. As a paying taxpayer we should not be sold faulty goods that may have dire consequences.
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!!!
