2017 Sierra Denali rear window EXPLODED!!!

poconojoe · February 19, 2020

This is a crazy thread no doubt. Can anyone confirm that this does not occur on the full solid window? I don't have the slide open rear window.

Yes it seems to be a problem with the connector on the sliding window. With all the opening and closing it gets worn and dirty and bent and creates a hot spot. The full solid windows have been fine as far as I know.

Thanks for the quick reply!

I Hope GM steps up and gets this resolved for all the owners that have the sliding window.

I can only imagine how that must feel when one hears that pop and sees that window shattered.

Not happy to report this but my full solid window shattered on me today after hearing the dreaded pop sound.

Oh, crap. Sorry to hear that. I have the full solid window also. I'm going to refrain from using the defrost. I turned off the auto defrost in the settings menu. Infotainment/settings/vehicle/climate and air quality/auto rear defog. I'm only going to use it when absolutely necessary. Then wait for a recall...

Good evening! Sadly this is my first post on this forum but I have lurked a bit. I own a 2017 Sierra Denali which I bought in May of 2017. I was driving today and after using my remote start to start the truck (like i do often) I drove 5 minutes and then smelled smoke. I turned around and saw smoke pouring out from behind the rear seat on the driver side. I began to freak out and pulled over to get out but about 10 seconds after I saw the smoke and began to pull over I heard a loud bang like a gunshot. I turned around and my rear driver window shattered into thousands of pieces. It stayed in place but shot a decent amount of glass inside and outside of the vehicle. I am dropping the truck off at the dealership in the morning to have this diagnosed and this is clearly something that should not of happened. I only think what would of happened if I had kids or people in the back of the truck when this took place. Very disappointed right now and want this taken care of, but figured I needed to post this on here to inform all of you about this issue. I have researched this happening and it is a common thing on some Ford f150s but I havent seen to much about GMC.

I had this same exact thing just happen to my 2016 high country last night. Did dealer cover this or you get any answers about this issue

I am still doing research. I had my rear defrost short out on my 2018 GMC Sierra HD last week. Luckily it did not shatter the window.

Dealership is telling me I'm not covered under the recall and they want $1400 out of pocket to replaced the rear window assembly.

Even my Ally Major Guard extended warranty denied the repair. Crazy.

Looking into other options. 44k on the truck.

I've reached out to GMC customer service. Waiting to hear back.

Also, does anyone know the fuse/relay location for the rear defrost. I want to pull that before things get worse.

Fuse box under the hood, try fuse #10.

Thanks Jim,

I'll give that a look in the morning.

You are very welcome.

Do not give up with GM, make sure you have opened a claim, and get the number, you will need it.

Really stress the point that you purchased an after market warranty from a GM dealership, and they are denying this too. Let them know you are upset, and want this to be taken care of, see how that goes.

If you start to lose traction, on this approach, start down the road of them helping you with the cost, this is when you will need help from the dealerships service manager, hope you have a good relationship with the dealer. They can do a lot more in helping you that they will let on.

It amazes me with how widely known and documented this problem is that any dealer would even try to say that you’re not covered. It went from the official recall fix being to just remove fuse #10 to actually replacing components on the window surface at the junction point where it closes. And yet some of them are still giving us a hard time about it.

I was going to try putting in a timed relay after I removed fuse 10 and then I just went thru the whole winter not once saying “jeez, I wish my rear window defogger worked”. So I’m just leaving it off. And tbh I don’t even know if I’d have any confidence in it not happening again even after the FULL fix.

The heated mirrors still work w/o the rear window so I don’t even think about it any more.

I completely agree. It is mind-boggling why they don't include all VIN numbers in the recall.
