SERVICE BRAKES
The brake pedal gets hard to push down when slowing down and especially when backing up slowly. After looking into some things I'm pretty sure the problem is with the vacuum pump.

ELECTRICAL SYSTEM, VISIBILITY/WIPER, UNKNOWN OR OTHER
On 9/22/2020 a recall service was performed on my defroster/ power sliding rear window under N192265660. On 1/13/2022 I was driving down the road with the rear defroster on, a smell of burning plastic and a low hissing noise. I was in the process of pulling over to inspect this and the back window of my pickup burst, sending me swerving onto the side of the road. I booked an appointment with the dealer, they are telling me they cannot replace this since the recall was already serviced. Obviously the fix GM is putting into our vehicles is as dangerous as the original design. This needs to be remedied and GM needs to be held accountable, bursting rear windows can cause terrible accidents, luckily I am safe.

SERVICE BRAKES
We recently had the recall installed on our truck, which was a brake software update for "increased brake pedal effort". No other work was performed and we had had no other issues prior to the recall being performed. Now, after the recall software update, we have all of the symptoms of the low speed increased brake pedal effort. There have been multiple times where we can barely get the truck to stop at low speed in a parking lot. The brake pedal vibrates and can hardly be pressed. Took it back to the dealer to complain about the recall installed and they said they would give a small discount for a vacuum pump repair but other than that there was nothing they could do due to our high mileage.

UNKNOWN OR OTHER
The only way to get the heater to work on your feet is to turn off defrost, turn on only feet, turn on AC and sync both sides. I live in North Idaho and when you do this your windshield fogs up and freezes. I have taken this to the dealership and was state "Works as designed by GMC". To me this is unacceptable. I drive 90 miles each way to the airport and have to decide what condition i can live with. Completely frozen feet and a clear window or the reverse.

VISIBILITY/WIPER
When operating my truck two days ago, I smelled something burning. I then noticed a small plume of white smoke coming from the rear driver's side window area. I then noticed my rear defroster was on, which I shut of right of way. About 30 seconds later, I heard a loud pop and I noticed the rear driver's side portion of the window was shattered. I brought my truck to the dealership and they said they could not figure out what happened. I believe it is tied to a prior recall, but they said my truck was found not to have any issues at that time. I believe there is a direct correlation with the recall issued and what happened a couple of days ago.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
Can turn vehicle off while in gear (drive specifically). When you let off the brake, the truck acts as if it is in neutral. Discovered in my driveway when accidentally forgot to shift into park when I pulled in and pushed the stop button. Truck turned off, which would only expect if in park (or neutral), let off brake, and it began quickly rolling backwards as if it was in neutral. Fortunately the brakes were working, but had any children been riding a bike on the sidewalk or walking by, my truck may have hit them. Had I been more distracted and not noticed initially, it could have rolled into the road and hit my neighbors truck. This behavior can be reproduced every single time, and I can easily supply video.

POWER TRAIN
When shifting into drive after reversing, truck will occasionally do a small thud and hesitate to move forward. This is from a stopped position after reversing, then braking, putting the truck into drive, then it happens when starting to move forward at very low speeds (I would say about 1-2mph). Vehicles recovers quickly, however it seems like a transmission mount or something may have issues. If another car were coming up quickly, or started going expecting you to start moving, the delay the thud and hesitation causes may be enough to cause a minor incident (assuming no high speed traffic coming up behind someone as they reversed out). This issue does NOT occur every time. I have owned the truck for 4 months, and it has happened only about 4-5 times in total.

ELECTRICAL SYSTEM
Used auto start, got in truck few minutes later and heard from rear window and a hissing and smelled electrical burning in the cab and saw smoke coming from driver side rear power sliding window. I shut off the rear window defroster and brought it to the Freehold Buick GMC dealership in NJ. They told me they tried to duplicate problem and couldn't find anything wrong. Returned to me with no corrective action taken by them. Two days later with the rear defroster on the drivers side rear window exploded and shattered while I was driving which startled me and almost caused an accident. When I returned to dealership they said it wasn't their problem as they couldn't find anything wrong and to replace it would be 1500 dollars. As of this complaint, I see there are 17 other identical complaints. There is also a customer satisfaction program (laughable) from GMC #N192265660 which identifies the problem and action the dealerships are supposed to take. But only for certain areas in the USA, Which mine did not. (purchased in PA, registered in NJ). How this is not a recall is ridiculous. It is listed as a "thermal event" Not sure how they got away with this. Its the incipient stages of a fire period. It involves a window which when starrers completes obstructs your vision and is a cut and blinding action if gets in eyes while driving. I implore the NHTSB to investigate this and order a full recall. It likely caused injuries or deaths already that are not known or reported as the reason for the accident/incidents.

POWER TRAIN, ENGINE, SERVICE BRAKES
at first my brakes began locking up on the vehicle, almost as if they were pumped full and not able to press down any longer, shortly after that the stabilitrack light came on and white smoke began to come out of the exhaust as well as a slight shake in the engine, i immediately turned the vehicle off and parked it, mind you i bought the vehicle 1 day ago and it is already broke down, the issue is with gmc and these sensors they are using they are faulty engine reduces speed and it is not safe to say the least.not only that but had the exact same problems with my Gmc Acadia which i finally got the light to stop going off after replacing transmission, brake pedal position censor, as well as gas pedal position censor, also had the throttle body replaced, Do you all make products that are worth anything, nothing was ever done about the Acadia, the Gmc sierra is a 2015 with 70,000 miles on it this car should not be acting like this please contact me at [XXX] thank you so much for your time, also there are 14 recalls on this year truck yet mine shows that there are 0 recalls to be fixed I am wondering about this as well.

My rear back heated window on the passenger side popped and shattered the window while I was sitting in the passenger’s seat waiting for my husband. The truck smelled like a sweet wire smell and then I heard a loud pop. I looked back and the back window panel was shattered. I do see that there were recalls on some of these windows.

STEERING
The power steering failed while operating the vehicle. Unsafe. Local GMC dealership Haggerty in Oak Lawn, IL not able to diagnose problem after fact. My safety and others were at risk. Not confirmed, as techs are not familiar with system. No warnings prior to power steering failure. Be advised, this is a hybrid pickup, and as such, does not have a traditional power steering pump system. Other GM models from the same era have had recalls, but the Silverados and Sierras were somehow omitted. The power steering assist motor has failed. Not the "brains", module.

SERVICE BRAKES
While driving parking lot speeds, when I pressed the brake pedal, it was very very difficult to push causing me to nearly rear end the car in front of me. This happened intermittently during a short time frame (5 minutes). While standing on the brake pedal hoping to stop in time, the brake pedal shook like the Antilock brakes were activating. This caused it to be even more difficult to stop in time. My vehicle is currently at my local dealership's service shop. When the issue occurred, a message stating "Service Brake Assist" popped up in my display.
