Has anyone had a spider gear failure? on 2006 Volkswagen Jetta TDI

I've had the car for 5 1/2 months and driven 10,000 miles, when the clutch went out and the spider gear exploded from the transmission. I was coming up to a stop sign and depressed the clutch, heard a pop and the clutch would not come back up. When taken to dealer, they will not cover under my bumper to bumper warranty.

Asked by for the 2006 Volkswagen Jetta TDI
this can happen in any car with a manual tranny. the warranty will not cover this because it's a "wear" item.
(BTW: no extended warranty EVER covers clutch parts)
I understand that the clutch isn't covered, but the transmission should have been covered.
