What was the weather like at the time of the moonroof failed? Was it really hot? Did you have the AC going? Was the moonroof liner pulled back at the time?
I have a hunch [theory] that this is more likely to happen when there is a large delta between the outside temperature and the inside temp.
Its was between 60°-70°
So it wasn't hot at all. We've in the PNW.
The A/C was not going
The headliner was shut. Thank God or it would have rained tempered glass pieces on us
