Absolutely have seen it. My garage kept C6 4LT experienced the same issue a few months out of warranty. Chevrolet said sorry - should have purchased GMPP. $2,100 for a replacement leather dash, however I procrastinated and the leather dash was NLA. I replaced it with a stock dash with the intent of repairing the original - which I still have not done. They used the thinnest 'leather' I've ever encountered.
Really poor assembly job on these dashs - you can see how little adhasive was used.
As for dash removal / installation, it's pretty easy and takes about an hour each way as most everything snaps together vs. screws together.
