why someone exploded the back glass of my new car

It was probably the heat from the sun. Tint ur windows or keep them cracked a bit

Did u find a rock in the back hatch or rather what type of car is it ? On a very hot day when l was young & we lived in the country..my mom is Ford Escort was parked on south side of our garage with the rear of car facing south..the windows were closed & as l said..it was VERY hot outside & her interior was charcoal grey. Out of bad luck l was playing in front of house not far from car & throwing rocks over tops the house to back of yard when l heard a loud ''POOF''. l looked to my right & saw the rear hatch window had shattered. l got blamed & l was not even throwing anywhere near the car & totally away from it. l am guessing it may have been a weakness in glass & heat made it explode.

Hi
l am really very sorry to hear about this.
There r ever so many disgruntled frustrated good for nothing loafers in this world who do not like to work or exert but simply be jealous of others & they eye these people & damage their new properties. l am aware of scratches being made to the side of brand new car just out of show room & parked outside home.Some urchins do this at times. Even when u drive there r quite a number of trouble makers who would come like hitting u or overtake u or do all sorts of gimmicks & get u into some accident but then they zoom away.
There r a lot of such unsocial elements who on the slightest pretext of any trouble in any area resort to arson, looting etc of public & private properties.
THIS IS THE DIRTY(BEAUTIFUL) WORLD WE ARE LIVING IN

l do not know why but l might know how.If you get a spark plug and brake off some of the ceramic(the white end of the plug)and throw it at glass it explodes and it does not make any noise at all.Trust me its true. l worked at a body shop and someone showed me(on a totaled vehicle.)all it takes is a very small piece and that is it a lot of gang members do this so nobody hears it.
