Power steering goes out and at time turn truck power off whenever i attempt a slow tight turn like backing into my driveway or making tight turns going into parking lots and/or spaces. Most recently, when attempting a u-turn at a busy intersection, power steering went out and engine died. I had to coast to the side to avoid moving traffic. Each time this issue happens i hear 3 dings all my dash & screen lights flash off then on with clicking noises. Dash info changes from speedometer to radio setting. If i look at screen quickly enough when this happens i would sometimes read “rear parking assist unavailable” or something like that. If air conditioning is on it would turn off then on. Doors will unlock then lock, all this happening simaltaneously while attempting to make a turn

I was towing a camper down Rt 422 in Butler, PA in my GMC truck when it suddenly caught fire. My wife was following me and alerted me to pull over as quickly as possible. I had no brakes and the gear shifter went straight up without shifting. The doors would also not open while the truck was filling with smoke. I got out using the manual unlock knob and am lucky to be alive. We had about one minute to try to extinguish the flames before it fully engulfed both my truck and camper. I filed a complaint with GMC. By what I am reading online there are many instances of fires and GMC does not seem to provide assistance. This is very unnerving and scary to say the least. I am sad and angry for this situation. This happened through no fault of my own and I lost absolutely everything. I was in the middle of moving to start a new job and lost many work items in my truck as well. I had to delay my start date for work. Now I am responsible for deductables, insurance increases and other items not covered by my insurance. Now I have to buy a new vehicle and camper but what will GMC do to help me? Probably nothing.
While driving down the streets, truck loses all electrical power, loses power steering,radio, gauge cluster power and engine dies. Happened several times today. It immediately all comes back on(so far) but could definitely be a safety concern if the conditions were right.
Rear window defroster started smoking and created a burning plastic smell. After turning off the rear defroster the rear window exploded/shattered in place. I see there is a recall in canada, but not here. This is happening here and I have read of many others with same issue. Fire and broken glass is not safe and should be addressed
Vehicle was stationary on the street, parked. I entered it, and turned on my front and rear defrosters with the setting on "hi." I turned around and verified that my vehicle had not been hit nor was any damage at all apparent to me. At some point as I sat there with the car idled and the heated air reaching its maximum temperature, I began to smell some foul smell in the cab that I believed was exhaust entering the cabin. I rolled down the window. As I brushed the snow from the front and began to drive away, I heard a noise that I believed was the snow falling from the roof. However, as I rolled away, I noticed a louder-than-normal cabin. Upon looking behind me, I noticed the rear right window within the sliding rear cabin window had blown out. Upon inspecting the area, I noticed that no snow or water was present inside. Given that we had received a lot of snow the previous evening through the morning, had the damage occurred throughout the evening or early morning, there would've been moisture present.
Supposedly the brakes have been fixed for the recall, however, if I am driving as low speeds like in a parking lot, the ABS will kick in causing me to not come to a stop when needed. I have almost hit several vehicles due to this issue. I have issues with the radio working, specifically being able to adjust the sound level. I have issues with the mirrors being able to move like they should. Both of the electrical issues are permanent, it does not matter if I am parked or driving, they do not work at all. This is by far the worst vehicle I have ever purchased. The brakes have been occurring for years and there was no change when it was brought in for the recall. The most recent issue is now my evap system needs to be fixed. I can only imagine what that will cost to fix on a vehicle that only has 100,000 miles on it. Can't wait to get that bill!

While driving home the other night both headlights failed at the same time. Lost both high beam and low beam. Tried everything to get them on with no luck.

When turning the wheel sharply at low speeds, the power steering suddenly turns off, as well as all other electronics making the vehicle difficult to control and posing a safety risk.
At slow speeds, mainly when backing and turning wheel when going forward at very slow speed, steering loses power. Also some times hard to turn when vehicle not in motion at all. The last time it happened all interior lights and radio flashed totally off and right back on. I heard a dinging/warning noise and a warning message flashed but went off before I had a chance to read it.
Sierra 2015 rear power window defroster over heated and shatter my driver side rear window. Prior to shattering, I smelled electric wires burning than pop. The vehicle was in motion around 25mph. The rear defroster was not on. It was 30deg outside and clear.

While parked and idling in a parking lot with passengers in vehicle, there was a sizzling sound followed by a flame flicker observed directly behind the driver's side, rear passenger seat at the bottom of the rear, driver's side glass panel. Shortly thereafter, the rear, driver's side glass panel shattered. My vehicle has rear sliding glass and only the driver's side panel shattered. Smoke and burning smell was noticeable. After online research, I discovered the gm recall #n192220470 related to 159,000 canadian vehicles. My situation matched the description of this recall exactly, but according to gm, my VIN# is not included in the recall. My vehicle is currently at my local chevy/gmc dealer for diagnosis and repair, but they don't seem to have much concern about the safety failure and told me the repair is not covered by warranty. To me, this is a serious design flaw and poses a potentially dangerous safety issue.
