Yesterday I was driving down the freeway, maybe 65 MPH when I heard a loud pop. I immediately started looking at my windows for something, my 3 year old in the back seat was terrified and told me something broke the window. Thankfully the next turn out had a CHP officer and I pulled over. I explained to him what happened and we both started checking the car. We didn’t see anything, I thought maybe a bottle I had in my car exploded or something but I couldn’t find anything. The officer asked about a sunroof and I forgot to check so I moved the sunshade back and sure enough the back panel was completely shattered. He looked at it, looked for a rock or anything that may have entered the vehicle and determined it looks like the glass popped out, not in.
I’m almost positive it just randomly exploded, nothing hit it. Has anyone experienced this??? It’s now completely gone, I was on a road trip and still have 6-7 hours left.
I found this article also. Hoping it’s covered under warranty. https://lemberglaw.com/chevrolet-tahoe-sunroof-exploded/

I've heard of it happening on a few (happy to report it hasn't happened on my '21). If you check out the NHTSA website there has been some reports there of it. I'd encourage you to report it there also as its a bit of a safety hazard in my mind.

Either here or that website it sounded like it might be tough to get GM to cover it under warranty but yet it really should be a warranty/defect type of thing.

It certainly can and does happen. There was in all probability a defective run in the glass manufacturing process, and the glass was not properly stress relieved at that time.

Im an insurance agent, i purposely upgraded myself to full glass coverage (not the typical repair) so i have deductible free glass replacements...

I'm also assuming you do not have any aftermarket tint applied? Rumors and myth's that those can cause heat/expansion issues and cause them to crack/break...

Pretty sure all vehicle glass is tempered except the windshield which is laminated.
Most of the time that's correct, but after 2011 or so, some cars have laminated front door glass too. My 2016 Explorer Sport is set up this way
