Far fewer of these updated keyboard are developing the problems than the older version, but the warranty still applies for a free repair. There is, apparently a third redesign in the pipeline. . . We will see if it solves the dust problem once and for all. I solved it by putting a keyboard overlay on my MacBook after I took advantage of a keyboard, top, and battery replacement. Very thin and solves the dust issue, not to mention the occasional splurting of my Diet Pepsi on the keyboard when I read something totally absurd the Democrats are doing.
