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 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.
Vehicle fails to stop properly at low speeds. Brakes become 'hard' and vehicle will roll to a stop. Brake lights appear to have a short and work intermittently.
Vehicle brakes feel like they lock up often I have to push as hard as I can, the dash says "brake assist" or something when they feel like they lock up. I've almost hit cars several times because they lock up like this and theres nothing I can do. Happens often and varying speeds 10-70!
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.

Tail light lighting strip spontaneously malfunctioned and stopped working. Vehicle has no light and no brake lighting which could have resulted in auto accident. Within a month the headlight has burned out resulting in a blinker malfunction. Vehicle was on highway when both lights malfunctioned
Driving the 2015 GMC Yukon, tried to apply brakes, brakes went to floor and no braking available. Had to jump a median in the road to get car stopped. Called dealership, they were aware and said drive it there, almost wrecked again pulling into parking ot at dealership. You cannot drive the car like this, very dangerous. Being told its a common problem that GMC knows about but will only fix if its 70,000 or 6 years. Not ok, fix the problem my car is still under warranty until 100,000 miles! vacuum pump, vacuum pump belt, brake booster, master cylinder and vacuum pipe all need replacing!!!!!! make a recall before more people are hurt!!!!
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. It happens all the time since around Nov 2018. It seems to be getting worse
Had an accident in 2018 air bags did not deploy and when tried to stop and pushed on my brake pedal, it was like it froze and I was still moving. I was driving 37mph on a city street when the accident happened.
On repeated occasions (from 2015 to 2019) I have experienced sudden acceleration at low speeds and sudden jerking motions. The transmission and speed controls are unpredictable and dangerous. This is hazardous and may result in a loss of control. I have also experienced numerous issues with the brakes including a stuck caliper at approximately 42,000 miles. I reported these issues and numerous other issues to GMC corporate, tustin Buick GMC only to be told that it was a software issue and things are satisfactory and safe. GMC contends that the vehicle is fine and declines to assist with issues. This is an ongoing issue. The date below is approximate. The mileage is approximate on all entries.
Brake pedal gets hard in slow moving and stop & go driving causing vehicle to be hard to stop with no break power. This situation gets worse when towing a trailer in traffic an down hill where you need the brake power
My GMC youkon denali has brake lights that are known to dealers to fail. Yet there is not a recall. I looked on the inter net and saw that there has been this problem since 2015 to 2018. Because of a joint that was soldered instead of a wire. I know why when I brought it in for recall that the service man looked at my stop lights.
Brakes are unresponsive and stuff brake pedals at low speeds. While driving at very low speeds the brakes will not engage and stop the vehicle. I was pulling into a parking stop and the brakes would not respond unless I stomped on them going less than 5mph. It happens often with the same scenario. Driving at a very low rate of speed and my vehicle will not stop when the brakes are pressed.
Within the last year on my 2015 my ac compressor has gone out, radio screen quit working, brake pump/booster faulty, and now rear brake light quit working. All seem to be very common in this year model. My car has less than 70000 miles on it!! GM is either doing a crappy job on their $60000 vehicles or a recall needs to be done.
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.
When slowly turning into garage, brake pedal became "hard" and required significant foot force to stop the vehicle. The condition has not improved and I will have to tow the vehicle to the dealership for repairs.
When towing a small camper and traveling at slow speeds my brake becomes hard and must be pressed very hard to slowly stop the car. This does not happen all the time but has happened multiple times and is quite scary. The vehicle travels further before stopping than with proper braking which has the potential of putting me in a dangerous situation. Dealer says it is a vacuum pump beginning to fail but there are no pumps available nationwide so I cannot have it repaired! notes about dates and mileage are for the last occurrence and as close as I can recall for each.
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. This occurrence should be addressed by the manufacturer and should be taken very seriously since the matter is literally a matter of life and death. I will be making an appointment for my vehicle to be checked out and will update the dealership findings.
