Query: Non-stick coating flaking off

Overall they are holding up after 3 months of use. But, the smallest pot has the non-stick coating bubbling and in some cases flaking off. These have not been abused- put in a dishwasher or abrasively scrubbed or put in the oven. I'm not sure if it can't handle the heat of the gas burner. Still, I have to stop using this one.
