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.20180221_155246.thumb.jpg.879f22a74290ed4f0e03ff15da7b4ffd.jpg

Yeah, just send your VIN to some random on the internet. That should be fine. Sent from my iPhone using Tapatalk

Your post makes absolutely no sense. It's already set up for me at the dealer tomorrow morning.

And how is this different from any random person in the world just walking up in a parking lot and getting it?   This rates up there with folks blacking out their license plates in photos!

eh not so troubling given how much electronics and crap are in vehicles now a days.  I'll be interested to hear what they say.  Rear defroster on that side going kablooey is my guess.

Many years ago I had this happen to the back seat side window of a 1979 Ford Super Cab. I drove up in front of my business, with the window facing the west. I was out of the truck about 45 seconds to a minute at most. I heard the pop of the glass and when I got back to the truck the glass was so hot it was smoking. I figured that the sun was at just the right angle, glass had just the right contour that made it act like a magnifying glass and it shattered from heat build up.

I've seen this issue over on the Toyota forums too,  there were a few guys with 4Runners that had exploding rear windshields.  I think in all cases it was the defroster shorting out somehow.

Couldn't even tell you. I don't believe so. Even if it was on it still shouldn't of exploded like this. I'll update this thread when the dealer sees it tomorrow

If it was remote started, there's a good chance the auto-defrost was turned on.  Check your remote start settings on the truck and see if the box next to "defrost on startup" or whatever it says is checked.

Yet again a sad story hallowed by the customer handling it wrong. Please I beg you call the gm service rep first get a approved service ticket. Then and only then move forward.
But anyways I know know you are enjoying you free Denali and the free money...Oh wait no... ok good luck...

Ok but please understand a dealer worker in their best interest and Always less than the Best you can get. FACT is you can get a free loaner truck and full repair. But the way you did it already you passed that up. I understand I sound like a ass hole but really I just hate the hustle of gm paid dealer service after fact. These truck are expensive and the customer deserves better and. Would have it based on federal law,warranty,and customer service laws. But please post how it goes and what they offer. Or pm me the vin and I can see it in real time. Best wishes.

My moms CRV did this a couple years ago as she was backing up in her driveway. The place that replaced it told her that they replace rear and side glass in several vehicles weekly that randomly exploded while driving. Guy said all makes and models he blamed it on the vehicle flexing and putting pressure on the glass. Doubt that’s what happened here but that was the first time I’d ever heard that one.

It happened to me about 25 years ago.   Toyota Cressida.  Parked in the carport.   I was pitching golf balls with a wedge from one section of my yard to another.   I mis-hit one I cranked.  Bottom left corner.  It was spectacular. Took almost 10 minutes to finally collapse in to the rear deck.   Enough time to go in and get a towel to catch most of it....

 

idiot.

Unlikely but the smoke and shatter could be separate issues.  Left side windows are susceptible to debris being thrown up from passing motorists.  I once had my driver's window blown out on my '86  Suburban at highway speed.  I was having glass picked out of my ear that night!

      Enjoy the new truck, it’s a beauty. I’m glad you’re keeping the OBS, I love those old trucks.

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.
