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).

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!!!

- Hopkinsville, KY, USA

There is and had been a known defect with 2015, 2016 and 2017 GMC Yukon and denali rear tail lights shorting out. GMC has not issued a recall, however, many have complained. The led tail light circuit board is cracks which causes a shirt that causes the lights to not work. If you search the internet, it is very clear this is a huge issue with Yukon owners. Yet, GMC will not issue a recall. New tail light cost $1,000. This is clearly a manufacturing defect. If you could please look into this, we would all be grateful. I am concerned my young family will be seriously injured if the lights stop working and they are hit in the rear.

Rear brake light assembly failing to light when brakes applied and there is not a notification to the driver. This is a manufacture flaw with the led light circuit inside the assembly. There is not a light out notification so the driver is not aware the brake light has failed. This is a safety issue and is an well known issue on the 2015-2019 Yukon. This is occurring often and GMC is having problems with supplying replacements because the demand is so high from the failure. GMC has also raised the price of the brake light by 30% from $425 to $675 not including labor. I called the dealer and they informed it was a high failing item and was on backorder and not sure when they would get one. Driving the vehicle without proper brake lights is a safety concern and not legal so left with little option but to stop driving the Yukon.

Rear brake and tail lights do not work intermittently. Sometimes the lights work and sometimes they don't.

- Overland Park, KS, USA

While sitting still at a drive through, brake pedal went to floor as if it had no pressure. Had no brakes! no matter how hard I stood on pedal the car would not come to complete stop when rolling. Blew through stop signs and lights because even at 10 mph could not stop vehicle from rolling. Had just got off interstate doing 70 mph. Down hill grade was impossible. Found out that this was a known issue by GM involving failure of vacuum pump booster. Many reports, hopefully not many deaths caused.

- Columbia, TN, USA

Both brake lights work intermittently. If you tap hard on it they sometimes come back on but don't stay on. I took to GMC dealer where they informed me they've had a dozen Yukon's in recently with the same issue. Dealer indicated issue is faulty circuit board that overheats causing the lights to short out. I'm out of manufacturers warranty. Extended warranty does not cover lights. Dealer charges $800 per light (part only).

Brakes don't work well when traveling at low rates of speed. Stopping requires brakes to be pressed to the ground and still may not stop. I have almost had several accidents even after having the issue 'repaired' last year. I've had the problem assessed at 3 different mechanics. I have had to throw my car into park to avoid hitting cars in front of me. Brakes fail while driving in places such as traffic jams, drive thru, school pick up, etc. This is a huge safety hazard and fear that my children may be hurt if this issue is not corrected by the manufacturer. Steering becomes nearly impossible when the brake issues occur. This is an ongoing problem for the last 1.5- 2 years. Also, the tail lights continue to go out even after paying hundreds of dollars for replacements.

- Lufkin, TX, USA

Very hard/ stiff brake-pedal. It's very hard to stop the vehicle at any speed. I already replaced the brake pads and the problem still continues, is a very dangerous hazards to the drive the vehicle in that condition. The hard /stiff pedestal is in the city and the highway.

Brake light failure. First on driver's side then months later on passenger side. Vehicle was in motion. Hundreds of complaints are posted on the internet yet GM will not recall.

- Apex, NC, USA

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.
