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.
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
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
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.
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.
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.
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.
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.
