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.

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.
