OK, final post.

Called DOT NHTSA: recalls are free. There's no way they should get
charged for required work.

Called VW: the recall is legitimate. They will inspect lower tie rods
and replace for free if there's too much wear. However, they will
charge if the owner can't produce a maintenance receipt for the
service where they would've inspected the tie rods after the recall
was issued.

Frankly, I can't see how they can charge. I mean, I really don't
understand the logic, here. If anyone believes they understand how VW
can require you to pay if you can't prove you had it inspected, please
let me know.
