I have had numerous repairs to electrical components in the truck. Most recently I have been getting the same wiring harness repaired on and off for almost 5 months now along with various modules that it damages. The dealer makes the repair and then after anywhere from 100 to 1000+ miles later the check engine light will come back on or another error message like Service Trailer Braking System. Wires keep breaking in the harness and the dealer keep repairing them. The dealer has been very good about this. This last time they repaired a broken wire and 2 more broke during the repair and had to be spliced. There is obviously a defect in this wiring harness. I have been in contact with GM but the truck is out of warranty and they do not seem willing to help out much. They suggested I trade it in, I just paid it off less than a year ago, and have put thousands of dollars in repair and maintenance into it since then.

Rear defrost/sliding window began to smoke. Eventually, rear window exploded and shattered with a very loud noise. The noise was so loud it had my ears ringing and unfortunately happened also while I was driving down the road which cased me to swerve abruptly. Fortunately, I was able to steady myself and pull of the road. Prior to the explosion, there was smoke coming from the window that was continuing to intensify in my rear view window as I was driving. I pulled over into a cemetary quickly and noticed the rear defrost button was lit. I quickly depressed it to kill the electrical current to see if it would stop the smoking from the window. It did then disapate. I took off driving again presuming I stopped the issue. Within seconds the right side glass panel in the rear window exploded. The vehicle or component has not been reproduced or confirmed by a dealer or independent service center yet. The vehicle has not yet been inspected by the manufacturer, police, insurance reps., as of yet but it will be shortly.

Was driving down the road at 65 and the truck shut down completely and had control of steering that time. Put truck in neutral and it restarted. Then was in a gas station getting gas then went to pull out after filling up and the wheels jerked and almost broke my wrist the instrument cluster said stibilatrac and shut down. Went to restart then the instrument panel said lower driver window then close. It did this one more time in the gas station parking lot.

I believe the General Motors Video Display Module Digitizer has a design flaw that affects vehicle safety. This is the appliance in the center of the dashboard to the right side of the driver controlling audio and clock operations. It is a large touch screen. Also, the instrument cluster located over the steering wheel is affected. This is the digital display that reports vehicle velocity, tire pressure, gas mileage. What are the symptoms? During vehicle operation, the video display to the driver's side will randomly cycle through alternate operations not requested by the user. For example, while listening to radio station "A", the unit will switch to radio station "B". Then, the clock will be displayed in "full screen mode". Then, the unit initiates phone calls to people from my contacts list on my phone. In addition, the display unit over the steering wheel is connected to the side unit and will randomly change display. Each time these units change operation, the system emits an audible beep. All this is distracting and increases the workload of the driver (talking on the phone while driving trying to explain that you didn't mean to call the person), thus representing a safety hazard while driving. While the misbehavior comes and goes, at its worst, the unit will change operation a few times per minute. I made a video of the misbehavior, which I can share with you upon request. The behavior is reproducible. Why do I say this is a design flaw requiring NHTSA safety recall? The unit is relatively new but past its warranty period: the vehicle has 57,000 miles. And multiple vehicle owners are affected: see web sites containing reports from other owners reporting the same problem with their relatively new vehicles: https://www.gm-trucks.com/forums/topic/252750-touch-screen-has-a-mind-of-its-own/ https://www.gm-trucks.com/forums/topic/255203-touch-screen-problems/ GM charges $900 to install a new unit, but I believe the problem is a design flaw and will occur again.

While turning out of a parking space. I went into reverse, when I tried to turn the steering wheel it turned the other direction. The dash went dim, stabilitrac message came on the information display and the truck completely shut off. I had no lights no anything. I popped the hood touched the +battery terminal and lights came back on. Was able to drive home

Rear sliding widow automatic defroster caught fire filled truck with smoke causing driver to make emergency stoppage and open windows to clear deadly smoke condition to breathe when glass shatteted and created loud noise and danger of shattered glass to rear passengers. Recall in Canada for same exact dangerous rear window defect.

The display on the radio touches itself. It will constantly change screens. It opens apps. It trys to make calls and send text. It is become a safety issue in the fact that it is constantly drawing my attention from the road. The center of the screen no longer is touchable, it doesn't recognize input. This is an issue alot of chevy customers are having.

The " service trailer brake system" light has been coming on for about 3 yrs in my truck. I have asked the dealer about this, and all I hear is it will cost me about $200 just to find out what is causing this. I was also told I could clear this just by pressing the dismiss button, which I have been doing. I don't feel this is the way to fix the problem. Since I do a lot of towing, I feel this is putting both mine and other lives in danger, since I don't know if my brakes are going to work or fail. I have recently discovered that this is a very common defect in this vehicle and is due to a faulty wire harness, which could fail at any time and cause a brake failure. I am truly afraid to operate this vehicle, and feel ALL 2017 silverado's should be recalled, and this faulty wire harness replaced, before people die.

Service trailer brake warning consistently flashing and dinging, every 1-4 seconds. Taking away my ability to see any digital read out on the screen, not safe to drive with this consistant relentless chiming and flashing on the screen. This issue has ready cost me a battery.

My truck has 57000miles has electronic steering. The steering will shut down and everything becomes manual. Steering error messages pop on the screen and chimes sound. This mostly happens at low speed, like stopping to back into a parking space. I've taken the truck to the dealership on two occasions, first time they " adjusted the module" for 1 hourly rate. The second time they reset the module and recommended a battery cable replacement. After replacing the battery cables and battery ( at a different repair shop) same problem. Now back to the dealership for a recommended Electronic Comtrol Module (ECM). After researching multiple websites and blogs, this is a known issue, and a dangerous one. Why has this not become a recall issue yet? https://shop.tekmetric.com/inspection/2D5vHKs-uXj8ZivBaJywx2vyFb4Lg9TyK5LgYX56mKE

My Service Trailer Brake System light comes on. This is the 2nd time that I have had to take my truck in for this issue. The first time it was fixed it lasted for about a year. I am not sure what the issue is, but there seems to be a lot of people with this same issue that is very concerning especially when you are pulling a heavy load and the trailer brakes stopped working.

- Ia - North Liberty, IA, USA

Trailer Brake system message comes on multiple time. Have never pulled a trailer. Also when going 75mph on cruise control the "Stabilitrak" message comes up and kicks off my cruise and completely blanks out my screens. This is extremely bothersome and is DEFINITELY a safety issue with this wiring problem.

- Independence, MO, USA

Stabilitrac service light comes on and dash lights flicker for a second, radio sound cuts out a second, then power steering is lost until putting in park or restart of vehicle. Just like recalls for other silverado 1500s. Happens intermittently.

(1). Entire Electrical failure. Initial investigation revealed Negative Batter Post and Cable extremely Hot. The Truck was operating perfectly and had just sat overnight. This issue was first detected about 1 month prior, when, after a 3 Hour drive, I got and when I returned, there was "Nothing". Disconnected Battery Cables, touched thwm together fo 30+ seconds and everything worked perfect. (2). The first event, I was in the Middle of the Arizona Desert, almost 90 miles from the nearest population. (3), Unable to Intentionally Reconstruct this problem. There was No Check engine light. HOWEVER - in the first event, the Stabili-Trak Light illuminated and had to pull to the side of the road to apparently let it reset. (4). Took it into the Dealer who simply stated "since there was No Check Engine Light, it would be a waste of money, since I had driven it in". They did not take a formal report. (5). Other than the initial issue with the Stabili-Trak light, prior to the first incident, 2/12 Hours later, there were NO advanced warnings. In the 2nd event, the Truck ran perfectly, parked it overnight and when I went to start it in the morning, NOTHING.

Pressing the brakes can cause the trailer brake system alarm to go off. Sometimes it causes the truck to die while I-€™m driving. Very dangerous. I have seen numerous posts online of the exact problem.

Trailer brake system is continuing to show a service warning on the dash. Noticed the problem when my battery kept draining over night. Then the service trailer brake system light came on and won-€™t go away. I don-€™t have any modifications done to the vehicle and I bought it used almost 6 months ago with 80,000 miles. The service light comes on every time you crank the truck. GM service bulletins are reporting that it is a wiring harness that is defective. This should be addressed as a recall. It is unsafe to pull any type of equipment as well is causing my battery to drain over night to where I-€™m having to jump the truck off just to crank
