While driving, my wife and I heard a bang, and when she went to turn her head, she noticed that the vehicle was smoking from rear defroster, and the back windshield had smashed. we immediately pulled over and the vehicle did not stop smoking until we turned off the rear defroster. This put our safety at risk as the entire vehicle could-??ve caught fire. When we went to check to see if it had been recalled, Our vehicle did not have any open recalls But we found that there were many other GMC Sierra trucks with this issue. We contacted our local dealer who confirmed that he had seen this happen to other GMC Sierra trucks. There was no warning light Or other indicator that this was going to happen. Unfortunately, Our vehicle was not included under recall N192265660 and we strongly recommend that another investigation is performed to include all 2014 GMC Sierra trucks. I have a video showing our vehicle smoking with a smashed, sliding Back windshield.

I am experiencing episodic loss of power steering assist without warning. This lasts for several seconds then power steering is restored. "StabiliTrak-?? message may be displayed during the event. On one occasion my radio also went off when my power steering failed. On one occasion my vehicle died shortly after losing power steering which almost resulted in me having a motor vehicle accident. I reported the problem to the GMC dealership and have scheduled the next available appointment to have it serviced.

- Austin, AR, USA

The vehicle lost ALL power, completely shut off with no warning while driving. There were no warnings or anything. Was stuck for about 5 minutes and had to let cars go around me (no power and no warning lights, so could not even use hazard lights). I did some reading and it people have said this could be a problem with negative battery cable needs to replaced. The vehicle started about 5 minutes later with no issues and had to reset clock and date.

The high and low beams quit working while driving at night. This caused safety issue for myself and other drivers. Fuses good and bulbs good. Have seen multiple listings online about the same thing happening to other owners.

Electrical glitches happen at both, low speeds and while on the roadway. My steering wheel tightens up and I get a message on the dashboard -??Stabilitrak-?? and another one -??assisted steering reduced, drive with care-??.

I know this is a well known issue with these trucks. Have had issues with power steering not working at low speeds which they claim it-??s do to low voltage. This has happened numerous times and then on May 3rd I went to back into my driveway off a busy state route with hills on each end of the road. Put my hazard lights on let three vehicles pass and then I turned the wheel and gave it gas soon as the truck got into the middle of the road it shut off. Everything stopped working no hazard lights for about 10seconds and then I had to put the truck into park turn ignition key off and then back on to restart the truck. Again this is all do to low voltage from what everyone else has said with the same issue. There are no warnings what so every even the voltage meter is fine and the truck doesn-??t hesitate at all it-??s like someone disconnected the battery. I-??m sure there is a way for GM to reprogram the pc for the voltage drop. At least have something like radio go out or ac, heat other than the engine and entire electrical shutting off. Something like this is going to get someone killed and GM should be held accountable for these problems.

Back up lights and Tail light problems My Back up lights turn on when the headlights are turned on and do not shut off unless the headlights are off. Also, recently, the rear tail lights were burning out early and would last only two weeks. The source of the problem seems to be in the fuse box. There is no short in the system. It appears to be in the fuse box of the 2014 GMC Sierra 1500. Bulbs were replaced and burned out quickly. Replacement parts are expensive and this problem exists on other Chevrolet and GMC trucks.

At slow speeds, multiple times, I have had the truck completely have an electrical failure and the engine shut off. I have replaced the negative battery cable and ensured all connections are good. This has happened on streets when turning and in parking lots. When this happens all of the screens in the truck flicker and the service stabilitrack light comes on and then everything goes out, to include the engine. Myself, my family, and other drivers have been out at risk when the truck completely shuts off on a street. The dealership has not been able to give me an answer. There are many forums online where the 2014-2018 year models of this and similar GM vehicles have had the same problem. We need a specific fix for this before someone gets seriously injured or killed.

Today I was driving on a residential road and my truck completely stopped while driving. My wheel locked up and I was unable to steer and almost hit another car. This has also happened a few weeks ago while driving on the highway at 70 miles per hour. My vehicle shuts off, I turn the key back and then restart it and I get the following 2 messages: 2 Keys programmed, and Open then close driver window. This is very dangerous and apparently a major problem with other vehicles as I have found the below additional details. This puts my family and others at major risk. I have asked to dealership to look at it but they state they have to keep it for several days and see the issue for themselves, and since it happens so sporadically I cannot be without my vehicle for that amount of time. Apparently it is an issue with the ground wires ands wiring harness. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://static.nhtsa.gov/odi/tsbs/2017/MC-10113356-9999.pdf https://www.youtube.com/watch?v=gvpsaDm-jj4

What component or system failed or malfunctioned, and is it available for inspection upon request" How was your safety or the safety of others put at risk?: The truck just stalls and dies without warning, all lights go off inside and outside and all power is lost. From digging on the internet, I found out the problem is due to one or more rusty/defective connection to ground which stops current from flowing and therefore stalls the vehicle and turns everything off. When the truck stalls, power steering and power assisted breaks are not available and this makes the truck very difficult to guide/stop for most people, making it a significant safety risk to occupants as well as others as the likelyhood of a collision increases significantly. In addition, since all electric accessories are disconnected, warning/flashing lights can not be turned on to advise others that the truck has stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem is hard to reproduce because it happens at random times, it has happened to me at least 5 times in the last month or so. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" NO warning messages or other symptom.

Service trailer brake system warning message. Trailer brake controller inoperable.

- New River, AZ, USA

Whenever driving I get a message stating that I need to service my trailer brake system. This is most likely due to cheap wiring installed by the manufacture. This has been going on for over a couple of months. Just recently, I was making a slow turn and my vehicle shut off on me and I lost control of my brakes and steering and all power to the vehicle which is a huge safety concern and I am unsure if they are related or not
