With time your rear view mirror comes out.
Rear view mirror fell off windshield chunk glass.
I ve seen this happen on numerous occasions twice to myself.
At times we see that rear view mirror fell off that creates problem to the driver.
It s a basic mirror with no special features.
The mirror on an 08 nissan altima fell off taking a chunk of glass out.
Basically an alcohol wipe and some super glue.
Maybe you can prolong the eventual cracking that way.
It s a bit odd.
If you are careful you may be able to get the glass off in one piece and glue it back in place with repair resin or rear view mirror adhesive.
Went to walmart and they had the permatex repair adhesive kit.
It s on a 2004 wrx and the windshield is aftermarket pilkington glass.
You can get the glass off the mirror button with a torch or heat gun and a putty knife.
If not you can fill the hole with plate glass resin or pit resin cure scrape and polish to get a smooth surface.
This is also true if you hit pot hole or bump.
Auto parts stores sell a rear view mounting repair kit thingy.
I work at a retailer where we used to install onstar mirrors.
You can use glue to put the mirror back on but if you live in an area were the weather changes from hot to cold or visa versa the windshield may crack.
There is a hole about the size of a nickel not completely through the windshield and the chunk of glass is still attached to the mirror base.
It s been a while since i ve done this.
You could try to fit that chunk back in there.
I was just adjusting the mirror on my 2004 wrx when it just fell off.
I pulled it down and noticed that there was a chunk of glass glued to the button and a roughly 1 4 asymmetrical crease in the windshield where the mirror used to go see below.
Yesterday i hopped into my 2001 a4 a secondary car for me and i noticed the mirror was dangling from the windshield.
