I got this recall for my 21 a month or so ago. They sent mobile mechanic who checked it and said my bolts passed inspection and didn't need to be replaced. So apparently no all recalls need fixing.
I got some thick memory foam and cut it to fit against the folded down bump. Then I put the Mabett dog protecting blanket over that. Works pretty good for my old man.

This is Murray before I fixed it up for him.
