Whoah! Sears is not being liquidated as they have accepted a bid from their largest shareholder to remain open. Further, even if they did liquidate it would not necessarily result in them being able to shed warranty obligations.
The OP's problem is not a design defect. Tempered glass can have hidden damage that causes it to spontaneously shatter. This is usually a manufacturing (as opposed design) defect, although it can result from damage caused after manufacturing.
The challenge for the OP is the warranty (which protects against manufacturing defects) has expired. I see two options:
1) Check with the credit card used for purchase to see if it offers an extended warranty
2) Nicely ask Sears for an accomodation, realizing that they would be making an exception
