Car window exploding from heat
So was wondering if a car window, drivers side or passenger side could explode during "hot" temps. Long story short, I have a 1994 civic I drive to work. Drove windows down. Parked car for 2 hours, go onto a 15min break and come to see the driver's side window broken in some way. Called police, they said the window exploded due to it being rolled up and it was hot outside. I live in Seattle, WA. It's no desert or anything but yeah, it was hotter than usual outside (82-85 degress). Nothing stolen at all, ignition and everything is in tact.
So conclusion to why the window broke?
1. Hot weather/window rolled up
2. Vandalism
Just curious so I can take more precautions where I park at work. I do have an alaram/other security measures/etc. Thanks

That is what I'm assuming. Probably some jack ass randomly breaking my car out of 100 out in the parking lot. Didn't steal anything. Co workers car are all rolled down with valuables. Everyone came out to check and nothing stolen. How weird? Made me think it was the weather...

Sunroof in our MDX exploded for no apparent reason.....just driving along. True story.

I've thought about this one, perhaps a small crack already on the sunroof or some imperfection and hit a little bump. Or something stress related? Freak accident really. But thing is, my car was parked, not moving.

We've owned the MDX since new, it's never been abused, in fact, it's been very well maintained. There were no marks anywhere else on the roof of the truck AND I took off the roof rack rails on day one so nothing has ever even been on the roof.
I say the sunroof glass exploded. Not a hit, not a bump and not chassis flex.

Not saying I know what caused the OP's window to break, but car windows breaking on hot days is not a new phenomenon. I don't think it is an internal pressure issue blowing out a window, but perhaps a temperature differential? Given the lack of evidence of vandalism or theft, "heat" is as valid as "vandalism," if we are looking for unprovable explanations.

I've come out to 140* interiors, no exploding glass. Rapid transitions from hot to cold can cause glass to break without outside physical force, but the heat alone that it will experience outside will not do it.
