RP179 side window issues

I would take the window to a glass shop, I'm sure they could just replace the piece that broke.  It's just tinted tempered glass.  Glass doesn't typically break for no reason.  Something was stressing it.  I saw a brand new picture window in a house shatter one time because the builder put too much expanding foam around it when he installed it.  The next morning it was shattered, the foam expanded so much that it broke the glass. 

I have a 2014 RP179 and love it, but while parked a couple of weeks ago, the side egress window slider shattered spontaneously - no thermal shock, no impact, no apparent reason, just shattered into a million tempered pieces.
