Mine is a '96. The owner of a '95 told me he replaced three moonroofs on his. UPDATE: Talked to him the other day: 1st moonroof leaked after purchased new--Lexus replaced. 2nd broke due to rock from gravel truck, but 3rd was a mystery like mine with no impact. There was no rock chip on mine and the fracture started on the very edge and with a month or two went all the way across. It doesn't leak (thankfully), 'cuz it's $1300 to replace. I love the car; I'm glad your replies indicate it's a rare thing.

A few months ago a small crack appeared on the edge of my '96 es300 moonroof, and now has traveled across the entire glass. The other day I saw a lady driving an es300 with her moonroff tilted and it was cracked. I talked to an '95 es300 owner and he said it was common... Has anyone else experienced this? Is there anything I can do to minimize the chance of it happening again? Thanks!
