While driving the vehicle I turned the rear window defrosted on. The rear window started smoking after 5 minutes of turning on rear defroster and filled the vehicle cabin with smoke. I immediately turned the rear defroster off and pulled off the side of the road and opened all the doors to air it out. I then went back in and turned the defroster back on to verify the rear window defroster was the issue. It instantly started smoking again and was scalding to the touch of the bottom right of the sliding window. I turned defroster off and waited about 20 minutes where I felt that it had cooled. After some research I found the TSB provided by GM. TSB # N192265660. I contacted GM customer service and they said there is nothing they can do and it will need to be fixed out of pocket. This is unacceptable as this may cause the window to blow out on passengers, or can cause a smoke inhalation issues. I had everything I could do the get the vehicle pulled over because I could not see. The truck is only has 56,000 miles on it.

Was driving for 25 minutes in the truck. Temperature outside was around 40 degrees Fahrenheit. I did not know the rear defroster was on. My son who was in the back seat smelled smoke and said that the truck was on fire. I pulled to the side of the road and looked in the back and could see the rear defroster on drivers side was glowing and emitting smoke. I looked at rear defrost light and it was on. I turned the rear defroster off to prevent any more current from going through the wire. Once we were sure there was no more smoke or fire we got back in the vehicle. About 300 seconds later the window shattered. If my son was not in the back seat and smelled smoke the back seat could have caught on fire. I called the dealer and they stated no recalls for my vehicle. There is an article from Canada describing what happened to my truck. https://gmauthority.com/blog/2019/07/gm-truck-recall-2014-2019-silverado-sierra-trucks-over-fire-risk/ No warning at all. The rear defroster just started smoldering and smoking. I do have a rear sliding window so only the left glass pane was impacted.

I bought my 2017 Chevrolet Silverado 1500 certified pre owned on 11/04/2019 shortly after I purchased it I started having problems with it. From brakes to lights. An took it in for the recall on brakes and steering. After that I've not had cruise control, and the stabilitrak warning light has been on. And just about a year ago while driving an pulling trailer, I lost communication to transmission, electronic brake, park assist, trailer brakes, ect. An was forced to stop! After taking it in to dealership to fix it, they did which lasted not even a month and done it again numerous times leaving me stranded. Now just last night 11/23/2021 while pulling my trailer, as I came to a stop sign I hit my brakes and all trailer brakes locked up bringing me to a stop (trailer brake on dash has been set on 0 since they haven't worked since purchased ) I had to unhook trailer wiring to make it home. As I took off I lost communication to transmission again and trailer brake system warning chime kept going off repeatedly, lost dash gauges, causing transmission to get hot. As it was stuck in a certain gear. Your defective wiring/ electrical system has fault and potentially caused a SERIOUS accident, and is going to cost me an enormous amount of money to fix. Also the torque converter has been acting up for a year, forcing me to purchase a tuner just to stretch the life of transmission. This vehicle is NOT safe to drive on highway! This vehicle is life threatening. Putting my life, my familys life and innocent peoples life's in danger! Problem needs resolved or reimbursement/ new truck. A $37,000 truck should not be life-threatening. This truck has spent more time in a garage than on the highway. Solutions have to be done. Why pay for a $37,000 truck you can't use or risk everyone's lives!

My vehicles trailer breaking system keeps activating cause the brakes to activate. Additionally, it is activating my stabilitrak system and turns the vehicle off and on. These issues coralate with recall #19V761000.

The system that failed is the speedometer display and radio display while driving. This can be dangerous as I do not know the speed I am driving. This can also be dangerous as the display includes the screen for the backup camera that turns off without notice while backing up. The problem has happened many times in the 2017 Chevrolet Silverado owned by the company I work for. I own a 2015 Chevrolet Silverado and the issue occurs in it, as well. I notified the GM dealership where both vehicles were purchased and they said the screen could be replaced but would be very expensive. No warning lamps or messages occurred. The screen jumps around a lot and occurs at various times (morning, afternoon, warm or cold weather, etc.).

I purchased a certified pre-owned 2017 Chevy Silverado on February 1st of this year, and over the last 4 months have put only 5,000 miles on it. On June 20th, on my way back from a 10-hour trip, where I was towing a trailer with a car on it, my trailer brakes suddenly stopped functioning (about 4 hours from home). Not only did the trailer brakes stop functioning, but a warning message popped up on the dashboard "service trailer brake system". But this warning message didn't pop up just one time, it kept coming again and again and again and again and again, relentlessly chiming and distracting me from driving, it covered my speedometer readout, it prevented me from receiving or making voice commands, prevented me from hearing phone calls, and prevented me from listening to music. The service warning chime also prevented the turn signal chime from functioning. So for a full 4 hours, I was constantly reminded with a service trailer brake system chime, was unable to hear my turn signal chime, was unable to listen to music or make a phone call, and was unable to see the digital readout of my speed. The vehicle had been rendered completely undrivable, and I absolutely will not hesitate to say that the vehicle was not safe to drive in that condition. Especially if you consider that I was towing 5,000 lbs with no working trailer brakes. GM's defective wire harness endangered my life. Consumer stated wire harness has not been replaced and manufacture refused to honor CPO warranty.

The back-up camera system has failed on my 2017 Silverado for the second time under 46,000 miles. Got to the point that the screen was just blue, not even a distorted image any more. With large vehicles like this I feel the camera is an essential safety component for backing up, especially in my neighborhood with children around, people walking down the sidewalks etc. The dealer had to replace wiring at about 7,000 miles (5mo old) and then wiring and the camera again at about 45,000 miles (4yrs old). The second time more wires broke during testing, triggering a check engine light which resulted in 2 days in the shop. The camera screen started saying it needed repair, would work on and off and then quit completely and went blue.

Twice on starting the vehicle the steering (the column unlocked)would not steer. It was impossible to turn the column no matter if I move it forward or reverse. No amount of twisting would allow it to steer. I worry it may fail in action on the road. The dealer said the steering module needed updating and then because it was 57 miles out of warrentee charged me $186. No garrentee it won't happen again.
