I'm regularly seeing tweets from the Piccadilly Line that say that there's
a shortage of available trains. Is this some newly discovered technical
problem, or the result of union action? This fleet is regularly reported
as LU's most reliable.

Here's an example from this morning: "Apologies for the gaps in the
service, this is due to lack of available trains. Our staff are working
hard to resolve this issue."

Could be leaf-fall wheel flats. A lot of the Piccadilly line is in the
open air.

Yes, you were right. But I wonder why it's worse this year than
previous years? I used to commute on that line every day, and don't
remember anything like this.
