Back up camera stopped working, appears to be dependent on the weather with temp and humidity. Back up camera will get all static then go blue and call for need of service.

The rear window defrost hasn't been working since I've owned the truck. Doing some research on it.....there's lots of complaints online with issues involving this problem. Some fires also. I did find that there were 160,000 or so recalled in Canada. Same issues. Mostly involving being remote started. Which is what happened to mine. I remote started mine....walked about 50 yards to the truck...heard a loud pop.....the rear window exploded ! Glass went everywhere !! It's definitely a safety issue....especially if someone had been in the rear seat !! I've ran the Vin # and checked with the closest dealer but they weren't any help. It's hard to figure there were so many issues in Canada....but none here. The replacement glasses are made in Canada, about every complaint I read involved remote start during cold weather.....which the rear window defrost come on if the temps below a certain level. Lots of owners were disabling the defrost on the rear window by removing the fuse and or relay.

I have had ongoing issues with my 2017 GMC Sierra Denali Truck's performance since it was purchased in May of 2017 of which I have all the service records to show. In mid-June 2021, the check engine light appeared on the dashboard and I immediately contacted the service department at the GMC dealership in Fremont to schedule an appointment. On 6/18, I dropped the vehicle off for the scheduled appointment. After picking the vehicle up, I immediately noticed that it was shuddering and vibrating upon acceleration of 30-40, 40-50, 50-60 & 75-85 miles per hour. The issue persisted and I returned the vehicle to the dealership on 7/1. After several attempts during the month of July 2021 by the dealership to fix the issue and it not being resolved, I finally contacted GMC Corporate to discuss the problems and options. I was assigned a case number and to customer service assistant Farris. Unfortunately, GMC customer assistance was not very helpful with my claim and was not responsive. At one point, I asked to be referred to a supervisor but was never given that opportunity. Finally, on 8/26, I was advised that based on GMC's evaluation and review of my case, the vehicle would not be replaced or repurchased based on the history of the vehicle repairs. He did not explain to me in detail the basis of this decision. He stated that my options were to take the vehicle back to the Fremont dealership or take it to another a dealership (where I may be charged). I decided to take the vehicle to another dealership which was GMC, Modesto. The appointment was scheduled on 9/14 and the vehicle was returned to me on 9/15 after they could not diagnose or repair the vehicle. The service adviser explained that I would have to return to the dealership in Fremont. On 9/17, the vehicle was towed to that dealership. On 9/23 at 4:55 pm, service manager Dave called stating "two fuel injectors they put in previously were replaced again and wanted permission for the shop foreman to drive it home."

Driving at approx 55 to 60 MPH with rear defrost on. Began to smell a burning/electrical smell, and within 90 seconds heard a loud bang. Rear window (stationary piece on drivers side) had shattered. Smell presumably coming from the rear window defrost component. No warning lights or messages on the truck. My son was sitting in the rear seat at the time so this is a huge safety risk. This has not yet been repaired. Window replacement is scheduled with Safelite on 6/8, consult with dealer on rear defrost set for 6/10. Photos are available.

I was towing a trailer for approx: 5 miles when I notice a strange odor and I pulled over and realized the truck had caught on fire by it self and police and good samaritin tried to put it out but was not successful. Hence the truck and trailer were a total loss along with $ 750 worth hand tools. ( trailer worth approx: $12,500) I was on a two lane road speed 40 (it was a rental truck)
