Parked my C friday and when I got back from running errands in the Jeep, I noticed the back window exploded/shattered. Looks like it was kicked from inside as it had a bulge in one spot. Glass is still there but ready to fall out in a million pieces. Taped the hell out of it inside & out and installed a plastic cover on the inside held in/pinched by the hatch door, just in case it does fall in. Being a newer model, all the auto glass shops don't have it listed by their suppliers. Toyota list price in Canada is 414$ plus install. At least it is stocked in Toronto, which should be here within 4 business days. That's a P-Off , but considering the window defrost on the glass, price isn't too bad I suppose. Same thing happened to me on a Hyundai Veracruz, I was rolling down the highway and the moonroof explode...a bit of a shock if I may say. lol Oh yeah, that reminds me, about 25 yrs. ago,I was driving a vehicle from Montreal to Florida and the driver side window exploded outwards as I was doing about 60mph...now THAT was scary, thought I'd been shot at! Just putting this out there, hopefully it isn't a problem with the C as it has been with some vehicles (other makes) in the past.
My father had this happen when driving down the road in Florida. It was over 100 degrees and he had the AC cranked. He moved the vent to the side so that it didn't blow on his face. Luckily he had window tinting or he probably would have been wearing the glass from the explosion.
I'd be very interested in knowing what caused this phenomenon. Sounds like Poser was not driving the car, so it couldn't have been an issue of inside and outside temperatures being drastically different.
Don't know if this applies to auto safety glass but: When I was much younger I worked as a dishwasher. Thick, heavy bar glasses out of a hi-temp dishwasher (140+ degrees) would sometimes explode when picked up from the glass rack. Shattered into small pieces - looked like rock candy and not very sharp. We'd just scoop up the pieces with our hands - almost never got cut. This did not happen with the thinner, lighter water glasses and wine glasses. Maybe someone can explain why this happened?
+1 - exactly what you said: Bormioli Rocco Rock Bar Stackable Rocks Glasses, Set of 6 by Bormioli Rocco Tempered Glass gives additional strength Stackable for easy storage and tight spaces Capacity: 9 oz Dishwasher Safe Made in Italy An article on spontaneous breakage due to nickel sulphide inclusions in tempered glass: http://www.eckelt.at/en/downloads/produkte/spontaneous_breakage_of_fully_tempered_glass.pdf In searching for spontaneous breakage of tempered glass - I found a number of articles indicating this is a well-known phenomena. Buildings have lost windows to spontaneous breakage - not pleasant for passersby if the building is tall.
Sounds like you don't have a lot of luck with glass in your car! Watch out for falling objects from overpasses now! Seems like you covered half of your other bases......the only time I had glass issues was larger rocks falling off an overpass while I was driving under it.
Thermal difference between the edge and the center of the glass. If the temperature difference is too great, the pressure from the INSIDE of the glass will actually cause it to shatter. When dealing with glass, its always safest to heat up slowly and cool down slowly. Rapid changes or drastic differences in temperature will make all but borosilicate glass shatter.
