2017~2021 Exploding sunroof...wtf?!

What was the weather like at the time of the moonroof failed? Was it really hot? Did you have the AC going? Was the moonroof liner pulled back at the time?

I have a hunch [theory] that this is more likely to happen when there is a large delta between the outside temperature and the inside temp.

Its was between 60°-70°
So it wasn't hot at all. We've in the PNW.
The A/C was not going
The headliner was shut. Thank God or it would have rained tempered glass pieces on us

Interesting.
There goes that theory...

usually good tempered glass is strong to some degree on direct impact from the top and is not so strong on its narrow sides.
 
Tempered glass is most fragile on the edges. A blow to the edge and it can shatter. The edges cannot have any contact with metal for instance and must be protected by means of rubber type material. I wonder if the issue has to do with how the glass in affixed to the frame and not allowing sufficient ”float” to the glass. I have not heard of spontaneous breakage where tempered is used in side glass that is frameless and vertical.

Hmm, have you seen this gentleman's Tesla? The side window exploded while sitting inside his garage....

IMHO, laminated glass should be used all around. It breaks but not into pieces around you or onto you.
 
Glad to hear they’re covering it. It looks like your moonroof may have exploded outward like ours did, though plenty of glass fell inside. It was the pic that showed the outward explosion that got Mazda to cover it in our case (and a fantastic service advisor). Hard to tell on my phone, but looks like the same happened to your sunroof. First thing we did on the new sunroof was to get tint installed, that way if it happens again we don’t get a glass shower
 
Well this happened to me on a 900 mile old 2021 CX-5 GTR. At 10:30am this morning when my wife left the house car was fine went out at 2pm to get a covid vaccine shot and the opened my car door and noticed glass and polen looked up and the moonroof was shattered and glass over the inside of the car was about 2 feet big of a hole. I was like what the hell landed in the car couldnt find anything.

Upon closer inspection noticed the glass was all pushed outwards like it exploded from inside out. The angles were much more sever then my pictures show but when I closed the door to get my phone camera a bunch more glass fell into the car.

The intial way it looked was a smaller whole 1.5ft to 2ft close to the center rear of the moonroof with glass angled all around it. Just had it towed to dealership. They were like we never heard of anything like this and agreed to talk to Mazda, hopefully it will be covered as its literally 3 weeks old.

Only thing of note is today was the hottest day of 2021 at 86 degrees and the hottest weather the car has been in this year so not sure if that played a factor.

That's ridiculous. Cars can get over 150°F inside when parked in the sun on a hot day. Absolutely no reason the sunroof should be shattering in moderate heat. Mazda better be taking care of it.
 
I really hope so since the car is 3 weeks old. It will leave a really bad taste in my mouth if Mazda doesn’t do the right thing here.

It’d depend on how favorable your Mazda dealer’s report is, and how good his / her mood is at the time when the rep at Mazda North American Operations is facing the case. ;)

Honestly, with only 900 miles and 3 weeks old on your 2021 CX-5 GTR, I’d be surprised if your exploding moonroof doesn’t get covered under warranty unless your dealer found obvious evidence of hitting by the foreign object like this which was happened last night in DFW area:
