My back window just made a loud pop sound. I have a back window that had an electic sliding widow. Which means the back window is in 3 sections (driver side, middle sliding window, and passenger side). The driver side of the back window was completely shattered. It's hard to see from the outside but from the inside it is spider cracked everywhere. I believe that I had my rear defrost on at the same time. Nothing hit my window to cause this.

I had my rear defrost on and it started smoking on the rear drivers side window and smelled like something burning and I parked at a gas station a couple of minutes later. The rear window completely shattered. The glass stayed intact but my 6 year old son was sitting in the backseat and it scared him half to death. I looked up recalls and this is known issue with these vehicles sold in Canada. This just happened and it hasn't been looked at my anyone.

Truck will experience complete electrical failure while driving in motion at various speeds. Failure lasts between 5-10 seconds but causes severe difficulty as steering is affected. A web search reveals grounding issue as potential cause. Manufacturer has not notified me of this particular issue and or any recall effort and I know of no existing recall effort for this issue.

Trailer Brake system warning continues to pop up on my dash along with the chimes. Not sure if this will affect my braking or not, but I pull a 32' camper and am continually concerned about this warning. It happens randomly not just when towing a camper. It has been in to a GMC dealer and they say nothing can be done about it due to no recalls.

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.

- Greenwood, AR, USA

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

- Montvale, NJ, USA

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!
