For most of the Bunn coffee maker models, you should be able to locate Bunn coffee maker parts to repair or replace malfunctioning components.
If you wish to stick with the name brand pot, you'll need to order form Bunn or an official retailer for the brand.
Sometimes, these baskets can crack, but they may be one of the things you never replace in a Bunn coffee maker.
Your first stop should be the Bunn's website.
They support Bunn coffee maker parts for new models released in the past few years as well as older models.
