NHTSA Complaint #11514806 — 2023 SUBARU OUTBACK

Moonroof shattered with a loud boom while driving on highway. Window and shade was in closed position and window had not been operated/open. Owned at 4 mi odometer and occurred at approximately 300 mi odometer. The loud boom was frightening. No glass came into the driver/passenger are because the shade was closed. I assumed the window had been hit by rock. However, a couple of hours earlier on the drive, I heard a clicking/torquing sound that I could not determine location. The clicking sound only occurred a few times and then was not heard again. No way to determine if this occurred from a rock or was a tempered glass failure.
