Sudden windshield crack.

A long crack, about 2 inches up from the bottom of my front windshield, appeared this evening. There was no recent contact with any flying object. What gives?

In the absence of an impact, the leading candidates are torsional
stress in the body structure or thermal stress in the glass. For
example, have you (or a shop) recently jacked up one corner or washed
the vehicle when it was hot? If the crack is parallel to an edge, I'd
suspect thermal.

Hmm. No. However, I did put on the defogger/defroster..outside temperature
at about the freezing mar. I noticed a TINY chip, right in the middle of the
crack line.

I had someone throw a rock at me in a construction zone (No surprise there)
, and I got a chip. Went in to work and parked. By the time the workday
was done I had an 11 inch crack. . . . But it was a cold day, too.

I think you've found your cause.

That chip is what caused the crack. In the future, if you get a chip in the
windshield, take it to one of those places that use epoxy to fill in the
chips to prevent a crack from forming.

That's chip is probably what started. When you were parked an object may
have been thrown up by passing traffic.

Last Dec. I had a very small something hit my windshield, right in front
of me. I saw no obvious damage, but the next day, after parking in my
unheated garage, there was a 1 ft. horizontal crack.
Looking closer I saw a very small pin hole on the crack line.

Ray, I know that. This particular chip was the next thing to invisible, it
was that small.

Yeah, that's pretty much what happened. Now, the crack, as long as it is, is
below the "line of visibility", i.e. it only affects my view of part of the
hood. That being the case, should I wait until spring, for more clement
temperatures? Or, is the structural integrity of the Camry affected by this
crack, therefore making it important to replace the windshield now, rather
than later?

I believe there's no structural implication. Some jusirdictions require
periodic official inspections of a vehicle's serviceability. A cracked
windshield can trigger rejection. Now that you know the weather wasn't
a factor the timing is your choice.

Nah, just all sorts of loose stuff on the road and one poor guy just
happened to catch this rock just right. . . . Happens in construction
zones. Most of the expressways seem to be perpetually under reconstruction.
(Maybe THEY lost the Civil War?) Sometimes when they work on a roadway they
don't clean up very well.

Nah, but I've never seen a crack go from nick to 11 inches in a mere 8 hours
like that before.[color=blue]
