I submitted my complaint. Only took about 3 mins. I urge everyone to do the same. FYI: What happens next? Your complaint will be reviewed by NHTSA technical staff and entered into our database.

Such information helps save lives, and we encourage you to share the resources available at www.SaferCar.gov with your family, friends and others in your community.

haha!!! well... i've tried opening/closing the rear window, restarting it remotely, leaving that defroster on..... nothing. bunch of bs... the fact that your trim is melted should be proof enough! looking forward to hearing what your dealer/gm have to say. Also, you should report it like the previous posters suggested. That's a serious risk to customers and it should start putting GM on notice. I am going to submit my complaint as well but I think mine is weak b/c I really don't have proof.

You didn't happen to take a video of it did you? When I jumped into my truck and started backing up, I noticed the smoke. It was THE ONLY TIME I didn't have my cell phone on me... Quickly, in my head, I was deciding "should I run and find my phone to record this shit, or should I turn off the defroster in case a wildfire erupts in my cab".... I chose the safe bet... -_- Just read an article on that recall. https://www.cnbc.com/2015/09/09/cadillac-ats-recalled-rear-defroster-control-can-overheat.html What kind of a fix is this?! "Dealers will update climate control software to remove a function that automatically turns the defroster on. Drivers will still be able to turn on the defroster manually."

HELL YES (I'm sorry for your loss)!!! But this is the kind of proof we need. Mine has only smoked but it wasn't on long enough to shatter the window or melt any trim. Thank you for sharing this.

The black box is closer to the passenger rear window but I am seeing all of the driver side rear windows shatter.

I contacted GM directly and they said to see the dealership. I asked specifically for a GM rep but one was not provided. The dealership I went to was helpful, but then again, my window didn't shatter. That could've been a way different ball game.

Thank you for that information! That is very insightful. As a side note, when I visited the dealership two days ago, of course the black box didn't short out. They said that the glass heated to 120 degrees as intended. Interesting, I wonder how hot the glass gets when the box is shorting out.

Yeah, absolutely. Especially being that it's a known issue, they should good will it.

Oh damn, you actually did get that on video. I didn't know you had it running. Something is really strange to me. The black square on my truck was smoking but I'm seeing the rear driver window shattering. I'm wondering if/how they are related.

Ahh. Did it get the whole thing on video :P? I'm still trying to reproduce the smoke issue so I can record it.

Update to my situation: But first, a summary of my experience: I remote started my truck (2017 Denali HD) about one month ago. I hopped in the truck and started to reverse. I noticed smoke coming out of the little black square on the center/sliding window. I also smelled a burning/short smell. I turned off the defroster. For whatever reason, my window did not shatter; perhaps I shut off the defroster in time? I visited the dealership two days ago. They called GM to discuss the situation. GM said that they have had multiple warranty claims for the rear glass but they have not been able to determine the root of the issue (not enough data, just shattered windows). (If I remember correctly), GM suggested to the dealership that they replace the glass. We decided against that because we don't even know what the problem is and I don't want them cutting stuff out that may OR may not need to be removed. So, moving forward, I am going to try to reproduce the issue and take video of the black box emitting smoke.

What is that black rectangle on the top left corner of the glass? Mine does not have that (I don't think).

It is my understanding that the truck will either trigger the A/C or heater/defrost/etc depending on the outside temp. Weird that hat the window shatters.

Lmao! Any chance youve heard any inside developments on this issue?

What happened to your truck? I saw smoke coming from my defroster so I turned it off real quick. Luckily my window didn’t explode. I havent had a chance to visit the dealership but I will next week.

I, too, was a little confused myself

How do I find out who is the local rep and how do I get in touch with him/her? Cant find anything on a google search.

You’re definitely not coming off as rude! And, I definitely appreciate your insight. I interned at a GM plant before but I never had the same exposure as you describe. What you described makes a lot of sense. I have yet to schedule an appointment with the dealer so based on what you’re saying, I’d rather contact a local service rep. When you say ‘local service rep’, I think that is the local GM dealership. How can I figure out who is my local service rep? I sent an email to [email protected] and they asked for my information in order to open a Service Request. Would this be the same as doing to my “local service rep“? I still haven’t sent them any information. Again, I really appreciate your time and feedback. Thank you.

So GM is aware of the issue? Do you work for GM?

Ah well hope they are able to do something for you. Yeah, this sounds more like a recall issue than a warranty fix. I’ll let you know what I find out on my end after I take it in.

Sounds like an awesome dealership lol. GM told me to bring mine to a dealership first. We should all somehow get a case or something going in case the dealers or GM say “sorry we can’t duplicate the issue”. Please let me know what GM says and I’ll do the same with you. I need to schedule an appointment next week. Any idea why your dealership said they wouldn’t touch it?

Hi Paul, I have the same truck. This morning, I saw smoke coming out of the window so I turned off the defroster. I am going to schedule a service appointment to have them check it out. I turned off the defroster before the window exploded. Any advice for when I contact the dealer? Anything specific they should be looking for?
