What would cause this?

Finished a night shift, drove home, backed into the driveway and went to bed.
On the way to work last night, I couldn't figure out why the ice on the back wouldn't melt. When I checked it out, the entire piece of glass was shattered, only held together by window tint.
Can a stone chip turn into this with temperature fluctuations? I couldn't see any particular point of impact

How do you get a stone chip on your rear glass? Getting tempered glass to chip without exploding is not an easy feat.

Some cars have a history of self-destructing glass (often sunroof panels). It is also simple enough for someone with a little knowledge to destroy a window quite easily. Are you sure this wasn't intentional?

A spring loaded punch would do it in a flash, but I don't know of anyone with a grudge that would do that. I'm in a small town, so grudges become public knowledge pretty quickly. My ex wouldn't have the know how. Maybe a random thing. I'd like to think there's a more benign explanation

My ex-wife had that happen at a baseball diamond to her brand-new Mazda 3 - foul ball. Don't park too close!

Otherwise extreme temperature change to flawed glass can do it.

Motorcycle holding a grudge that you stopped riding her???

Seriously though that is quite strange. How old is the vehicle?

Yeah maybe. She knows it's not over yet though.

It's a 2012. A search on the interweb shows that it's not common, but spontaneous shattering of tempered glass is a thing.

It's a common problem in some cars... For example my F-150 with rear defrost and power sliding window it's all but a guarantee every couple of years.

It can also happen when the rear defrost starts to get defective and develops hot spots.

Go to a glass shop to get it fixed, most insurance policies cover it with no bump in premiums... Which for me was good cause mine is about $800 in parts and $200 in labour

I actually saw it happen once. I was stopped behind another car at a light and their rear window just shattered.

I worked for a window and door company years ago and sometimes we got a bad batch of tempered for patio doors. The odd one popped.

Tint in some cases can make it worse by absorbing heat.

I don't know if insurance automatically covers glass any more.

Good luck with a resolution

Thanks for the comments. I shopped around. No one was interested in waiving the deductible since it wasn't a very expensive job compared to my 500$ deductible. After calling a few places, I got it done for 350$

I'm going to look at another Kia to compare. It looks like the new glass is spaced away from the metalwork a little bit. Otherwise it seems fine.

I did it when I was younger with a bb gun. Cheap gun, cold morning, bb went off on a tangent. My dad's little Toyota pick up truck, back window splintered.
