The truck has only 122, 230 miles and shuddering in the transmission is horrible. I just purchased the truck 3 weeks ago and the owner stated nothing was wrong with it. However I took it to mechanic for inspection after purchase and he stated transmission has shuddering. I noticed at 40 miles plus the truck vibrates at steering wheel.

I was driving my GMC Sierra upon entering the highway, I was at a stop sign waited for clear traffic when it became safe to do so, I entered the highway and upon excelling up a small incline the vehicle transmission just completely stopped working so as I depressed the accelerator the engine would would wind the RPMs up but the vehicle wasn't going anywhere. I pulled the car over to the side of the road and placed the car in park. Put my emergency lights on and couldn't get the truck to the to go to the area to be free and clear of traffic to transmission engage. I put the car into reverse this is the second time this has happened and this is what my husband recommend I do. When I called him is to place the vehicle in reverse reverse a little bit and then place the car into park and then turn it off. Start the car up again and see if it would engage the gear, it took placing the vehicle in park. After adjusting the steering column and trying it again, the transmission engaged but would not reach the full acceleration. I was on a hill so I put the brakes on and the car brakes would not stop the vehicle. It would bounce and skid a bit as I was on an incline. The transmission was not engaging in reverse either. After resting then it didn't get any speed. There are RPMs just kept whining out. I wasn't able to at first get the car to go into gear after wiggling or adjusting the steering column then it seemed to go in gear but it would only go a few feet and then it the process would start over. this was dangerous as I was on a highway with an incline which means I had no break ability so I was rolling without control. I was able to get the car home and parked in my driveway but as this is the second event that has happened since we purchased the truck I'm making this report. Feel free to contact me if needed

I have not yet been notified by the manufacturer regarding the recalls on the vehicle.

I was driving and my nephew says there was smoke in the truck then all of a sudden there was a huge pop and my rear passenger window shattered! I had found online that this has happened to several people but there is no recall in the US. Something to do with the remote start putting on the defrost and the connection exploding. If this is happening a lot i believe it should be replaced.

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.

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.

While operation my 2015 GMC 1500 DENALI Pickup at normal conditions my vehicle produced a engine light. I was three blocks from my office so I proceeded there immediately to have my vehicle scanned for codes. This is where I found out that cylinder #7 had an issue. This cylinder is part of the AFM system. I had the vehicle towed to Galles Chevrolet for diagnostic services and an estimate for repairs. Up receiving the results (which) I will attach. Bank 1 and possibly Bank 2 lifters and springs have failed. Thus possibly cause damage to the cam shaft. While I am aware that my vehicle is out of powertrain warranty (5 years / 100,000 mile), my vehicle only has 52,000 miles on it and very very well taken care of at all times. I am also aware of a class action law suite that pertained to the same exact issue on gm products from 2004-2014. Also service bulletins were produced by GM pertaining to this issue. Now I have been out of service of my vehicle for 3 1/2 weeks not to mention a potential $7000 repair, that should have never been in the picture! Poor quality control on products for potential profit gains have cost many many customers pain, anguish, and money.

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, a message pops up on the display that reads: "warning taking your eyes off the road too long, or too often while using this system could cause a crash, resulting in injury or death to you or others. Focus your attention on driving" seriously, when a warning message pops up, we read it! I have gotten use to this stupidity and just hit ok. But even at that, you still get distracted. Problem now, is that even hitting ok does not clear it. This message should never happen. I have read that this a big issue among many GMC and Chevy owners. GM is literally creating the safety hazard.

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.

The vehicle always has a smell of dampness after a rain. Somehow water is getting into the vehicle. I have replaced the seal around the third-brake light which was thought to be the culprit, but no fix. The rear seat metal has rust on them from the damp. The driver's seat creaks when making turns. It is like it about to come apart. There should be a recall on this. People could get hurt if it happens. Le under the vehicle, I noticed that a body-mount is missing under the driver's side. This could be the reasons for the creaking. I am not sure!

I was driving down the road about a quarter mile from my house and the rear windshield on the driver side of my truck shattered. This is after I had them look at the same window for the defroster no longer seeming to be working. I've done research and seen the service bulletin N192265660, however my truck is not covered.

Symptom of hot air blowing while using the A/C, stationary or while operating. Filled with coolant which only lasted about one week. Reviewed forums and tsb's to note a common issue with the condenser. Dealer wanted to diagnose and replace items in order that did not include replacing the condenser at the top of that list. Purchased a third party condenser, vacuum pump, and necessary fluids and accessories and replaced by myself. A/C has been working reliably for several months. Although I saved about 2K dollars (all materials cost about 500 hundred dollars), it's clear that this issue is known and should be a recall.

I bought this new on Jan 3, 2016 on July 26 26, 2019 while from waco to ft. Worth Texas, my ac compressor seized and blew destroyed the serpentine belt. I had to replace the ac compressor and belt. 31,000 miles but out of warranty. Last week I was driving home from work and felt the ac was again blowing hot air. I took it in and today 06/29/20 I have to replace the ac condenser as it has a leak at a weld point. I have read dozens of complaints that this is a known issue and defect. I will now be out over $2,000 for a known problem and issue. I have read the tsb, watched news reports and on-line forums. The tech at my dealership said this is a super common problem with these vehicles. That seems like it would lead to a recall.
