2017 GMC Sierra 1500 Electrical System

While the 2017 GMC Sierra was warming up via remote start, I noticed a smell of smoke as I walked by the passenger side of the truck. Then I heard a loud bang as I was walking around the rear of the truck. As I entered the truck from the driver's door I saw the back window, passenger side, shattered. The vehicle was then turned off. According to our dealership the vehicle was looked at under recall N192265660 and deemed safe in May of 2020. A call was placed to GM who said the recall expired in 2022. An offer was made by for payment assistance by the GM representative but could not say how much until we pay the dealership for a diagnostic. This is a know issue by GM. The location of the shattered window is situated inches behind where my child's head would have been had she been in the vehicle.The smell of smoke is extremely concerning because where there's smoke there's fire.

Started car via remote start. When I went out to the car I noticed smoke in the cab. I then observed the rear power slide window to be smoking and further discovered the rear defroster wires the be smoldering creating considerable smoke. The tempered glass then began to spider and completely cracked. There is a former recall on the rear slide window involving fire hazards and the wiring components. It should also be noted that our 9 month old’s car seat is directly below the window and defroster wiring were the smoldering took place. No warnings lamps were observed prior to the incident.

Rear defroster failure. The rear defroster was turned on causing smoke to appear from the power sliding rear window, then the rear window shattered causing glass to fly into the backseat and truck bed.

Reverse lights stay on. Causing the battery to drain. The fuse box under the hood is prone to go bad. Even with no corrosion. GM knows this and has not fixed the issue. Its a common problem going back many years. The need to upgrade the fuse box under the hood & the wiring harnesses. My taillight harnesses were completely burned up. The truck could of caught fire. This should be a recall. Instead GM wants to take the money they are making off all the fuse boxes they are selling.

Approximately 3 miles into my trip i smelled something burning, thought it was a tractor trailer in front of me. Then my cab filled with smoke, I pulled over on the side of the road and examined the truck. The rear sliding window on the passenger side was cherry red and smoldering. I shut off the rear defrost, the cherry went out then the window shattered. No warning or beeps. My passenger and my safety were at risk to smoke inhalation, the possibility of a wreck, or burning. Gm claims there is no recall on this. But Canada has 159k recalls on this. Vehicle has 120444 miles on it. Temperature was 45 degrees out today at time of incident

Started truck for 10-15 minutes with front and rear defrost on to remove ice from glass. Upon entering the truck, there was a smell of wiring/plastic burning. Smoke was coming from the bottom corner of the rear sliding window. I immediately shut off rear defrost and then shut my truck off. Then the driver side rear glass panel popped and shattered completely.

In January 2024, I parked my truck in my garage and shortly after I smelled an electrical burning smell in our house. When I opened the garage, it had smoke throughout the garage and a very strong odor of electrical burning smell. I moved my vehicle outside and tried to find the source, but it was too strong to narrow it down, and the garage smelled like burnt electrical for days. I took the truck to a service shop and they could not find anything wrong at the time. Today, May 2024, I was having trouble getting my trailer lights working. Upon further inspection, I discovered the 7-way interface wiring harness on my vehicle had electrically shorted out and melted a hole in the plastic housing and left melted plastic on the truck frame. The tag on the wiring harness states TAG #138359 7-WAY INTERFACE HARNESS W/O 134971. I believe this electrical short/fire should be part of the NHSTA Recall 18E-014. That recall states those are aftermarket harnesses, but the harness on the vehicle in this complaint is original to the vehicle and was installed by the manufacturer. I plan to take the vehicle back to the dealer to have the harness replaced, but I am expecting pushback since the NHSTA recall states this is only aftermarket harnesses.

Infotainment System will change stations, stop navigation / change navigation destination, stop / start playing on its own. Examples of recent issues: 1) While driving from southeastern Ohio to West Lafayette, IN, the navigation system (Apple play through the infotainment system) stopped navigation to entered destination and changed destination to home. This occurred while in Indianapolis and caused us to reroute until we noticed the issue. 2) While playing music from bluetooth, the Infotainment system changed from media play to radio play. The change in volume and music caused me to swerve suddenly while in downtown traffic. 3) The radio changed stations continuously for 5 minutes, changing screens and stations for 5 minutes until I finally shut it off. These are just a couple of the examples. Something happens every time I am in the vehicle, the extent varies. All of these situations cause the driver to lose focus of driving, and also create a shock when first happening. After investigation, I have found that many owners of 2017-2020 GMC vehicles with the Infotainment system have the same issue. Some have fixed the problem by installing new systems (GM offers an "upgraded" system that doesn't have the issue... Coincidence?). This leads me to believe that GM acknowledges there is an issue but will not fix it as a recall. I have video of the latest occurrence, but the site will not allow the file type to be uploaded.

Driving down the road. Thankfully it was late at night and the roads were empty. But the truck shut down and brakes locked up and steering wheel locked. Once I was at a full stop. I turned the truck off and back on and was able to drive home. But I called Gmc regarding this issue and brought they couldn’t find anything wrong

Rear window defroster started smoking and broke my back window. Known issue. Recalled only in Canada not in US but US vehicle having same issue.

The contact owns a 2017 GMC Sierra 1500. The contact stated while driving approximately 10 MPH, the vehicle lost motive power and stalled. The contact stated that various warning lights were illuminated. The vehicle was towed to a local dealer where it was diagnosed with needing the battery cables replaced however, the vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 48,000.

The front driver side window won’t roll down or engage; the a/c blows warm/hot on the drivers side vents; the stereo system continues to, “Glitch” changing stations, displaying other information without the screen being touched. These often cause discomfort by not operating properly. The dealer did not suggest any concerns upon my purchasing the vehicle. Vehicle was never taken to a certified GMC dealer for these issues.

WHEN REVERSE IS ACTIVATED AT NIGHT, THE BACKUP CAMERA COMES ON AT FULL BRIGHTNESS AND IS NOT DIMMABLE. THE BRIGHT SCREEN PREVENTS VIEW OF THE PASSENGER SIDE MIRROR AND SIGNIFICANTLY REDUCES VISIBILITY IN THE DRIVER SIDE MIRROR WHILE REVERSING. THE SCREEN CANNOT BE DEACTIVATED AND BLINDS THE DRIVER. THIS IS AN ONGOING ISSUE.
