The brake/tail lights work somedays, and not other days. One day the are both working, one day only one works, and some days neither work. This is a problem that is very prevalent. Just look online. I have personally photographed several of the same issue on this make and model in my hometown. The dealership wants me to pay $1300 to have new lights installed and gmc is in denial of their problem.(the back up/reverse white light works all of the time, its the red brake/tail light that doesn't work) this shows that its an issue that should be recalled, not replaced at the owner's expense.

Tl* the contact owns a 2015 gmc yukon xl. While driving 60 MPH, the rear driver's side brake light failed to illuminate. The vehicle was taken to five star chevrolet buick gmc (located at 495 watson blvd, warner robins, ga 31093, (478) 387-4424) where it was diagnosed that the brake assembly needed to be replaced. The vehicle was repaired, but the failure recurred approximately 5 months later. The contact took the vehicle back to the dealer for repairs and an oil change. The contact was informed that lifters on the engine and condenser line needed to be replaced. The vehicle was not repaired. The manufacturer was notified. The failure mileage was 96,000.
While on vacation he brakes started fading, especialy at slow speeds. Creating a very unsafe situation at highway speeds. My dealer says they have not had any problems but it is all over the internet.
While driving my yukon, I was preparing to stop a light only to struggle with pressing the brake pedal, almost hit a vehicle that was in front of me
Takata recall driver side brake light stop working while driving in the city streets
Intermittent brake light activation on both left and right. It happens stopped and in motion. Very dangerous! It is a known issue with broken contacts inside a sealed housing. The issue is posted all over the forums but gmc refuses responsibiliy.
Power breaking fails when driving at low speeds, brake pedal stiff and hard to push down to stop vehicle in both forward and reverse directions when inching forward at a stop light/sign, or parking in a parking lot in forward and reverse car keeps moving. Stopping required very hard push on the stiff brake pedal.. Braking at higher speeds less affected but sudden stops can require more force than usual as the car slows down. Problem began december 2017 rarely and intermittently, and increased to all the time by february 2019 at low speeds the power brake did not work and required much force on the brake pedal to stop vehicle every time. Brake fluid was fine and so was brake pads. Gm dealership visit showed a failure of the vacuum pump for brake line and they installed a redesigned pump which shows that the original has faulty design. They also required a belt that operates pump to be replaced as well. This seems to have fixed the problem for now but this repair has a two year guarantee. Price for me to fix over $881+tax.
I lost brakes. Extreme pressure on peddle required for brakes to engage. Even then only reduced braking power was available. Required replacement of vacuum pump and booster. Occurred when vehicle engine was at idle. Otherwise brakes felt week but available.
Brake pedal is stiff at low speeds. The pedal locks up and stopping is delayed 2 to 3 feet. It makes operating the vehicle unsafe. I have done research on this issue. Others are experiencing the same dangerous delayed stopping distance and stiff brake pedal at low speeds.
From time to time brake pedal becomes hard when backing up or going forward making the vehicle hard to come into a complete stop.
The brake lights on my 2015 gmc yukon xl have both gone out. I have been pulled over and questioned about it several times by my local law enforcement. I believe the manufacturer state that they have a life of 40,000 hours of continuous use but, only function for a fraction of this amount & they are $600-700 to replace.
When coming to a stop, the brake pedal became stiff and did not engage. This has happened on multiple occasions in the past, and happens when the vehicle is traveling at slow speeds (less than 5mph). The issue is a faulty power break pump.
Today, while coming to a stop, the brake pedal became stiff and did not engage. This has happened on multiple occasions in the past, and happens when the vehicle is traveling at slow speeds (less than 5mph).
We purchased this vehicle on 11.21.18 and the brake lights intermittently don't work. They were working at the time we drove it off the lot. The bulbs were tested by our mechanic and he stated that the gmc yukon of this year are known to have major problems with the brake light housing units on the rear of the vehicle. The electrical board associated with it has issues the mechanic stated. I reviewed many post online and wonder why this isn't a required recall. To me this is a major safety concern and we bought this vehicle to transport my kids and wife. I'd like this to be considered a recall immediately.
Tl* the contact owns a 2015 gmc yukon xl. While driving 5 MPH and low speeds, the brakes seized. When driving at higher speeds, the brakes performed properly. The contact would have to place the vehicle in neutral and rev the engine for the brakes to work. There were no warning indicators illuminated. The vehicle was taken to seilveira buick gmc (985 healdsburg ave, healdsburg, ca 95448, (866) 572-7256) where it was diagnosed that a new vacuum pump needed to be installed. The vehicle was repaired. The manufacturer was made aware of the failure and did not assist. The failure mileage was 105,000.
While in motion the brakes went out completely in july 2015. Then while driving down the interstate at 75 MPH the brakes went out completely in 2018. Both times I was charged a deductible. Both times the complete brake system was completely replaced by a dealership. After the second incident I contacted gmc. After numerous phone calls the offered me $2000 towards a new vehicle. I was very upset with them and threatened to get a lawyer if I was hurt in this vehicle or hurt others in the future. It was a terrifying experience and I felt like I deserved more. They wouldn't even pay for the rent a car I had to use on my vacation while the brake system was replaced. I paid $70,0000 for this car, but don't want to fear loosing brakes ever again!
While operating the vehicle and attempting a stop the braking became poor and I had to depress the brake pedal as hard as I could. However, even after that the vehicle did not stop right away and took more distance to come to a full stop. The brake felt "soft" and not like it usually does. Interestingly...the brake would seem to work again immediately after the incident. I've had probably 3 or 4 incidents, over the past year, where this has happened. None of the incidents have resulted in any traffic incidents, but all have required more stopping distance than normal. All of the incidents have typically occurred at lower speeds (less than 40 MPH).
When moving in a parking spot the brake pedal became hard as if it lost power brakes, but then returned. A few days later on the freeway traffic stopped in front of us and it happened again. This caused us to need to swerve to avoid causing an accident until we were able to come to a stop. After several miles the power brakes have not returned. There is oil in the vacuum line at the booster and gas mileage ya been poor the past few weeks prior to this. It all points to a faulty vacuum pump. 121,000 miles on the truck.
Brake vacuum pump failed. While towing a boat and backing up my brake pedal went hard when I pushed down and my vehicle would not stop. I was able to steer out of danger and eventually come to a stop.
My passenger front light cover is acquiring condensation which makes the lights go off and on, and my driver side brake light works only intermittently. My insurance or warranty won't cover anything to fix these light issues. These issues started about may 2018. We weren't in a wreck or sustained any damages that would have LED to these issues. I have talked to two other owners of the same make/model/year vehicle and we all have safety issues that are not being resolved by gm vwarranties. I want to see gm issue recalls and accept complete financial responsibility for repairs. I would also like to see the rear lighting system redesigned so the components are not dependent on each other. My brake light went out and instead of being able to replace a bulb the entire unit has to be replaced at $1700.00 that we just simply do not have.
My right side brake assembly seems to only work when it wants too. Works on cold mornings, but as the day gets warmer the light assembly doesn't work anymore. No lights, or brake lights.
While driving at slow speed in school parking lot brake pedal failed to stop vehicle when using normal brake pressure. Pedestrian in front of vehicle jumped out of the way to avoid being struck.
Wife and three kids in vehicle, stops on hill seems to have shifted into neutral. Goes backwards down hill flips over lands on roof. No injuries thank god! Vehicle had been back for transmission recall twice, the last time they said they had to wait for parts... Mind you the vehicle is brand new. Someone needs to get these off the road now!
...wife stopped on hill to speak to son.. I believe at this point the vehicle went to neutral, when she try to go forward, it went down the hill hit a pole and rolled over.
