I'm not sure if I'm in the group. I can definitively say I suddenly lost about 12% range briefly, then restored to where I'm only down 5.5% from before the major limitation.
If you receive the notice in the mail then you are part of it. But I wouldn't wait for the notice to arrive (lost mail to be an example) and instead would contact the settlement administrator (the info is on the settlement website) and just ask if your VIN in on that list.
I am, for example, on the list since I received the letter last week.
