If you look around on this forum, there's a good amount of discussion on the brake situation. Personally, i've had mine since January '03 and haven't had a similar occurence as of yet. You can't blame everything on driver inexperience so i'd guess there's some truth to their concerns.
As far as your question vis a vis the regular Legacy line, one of the things you cite the report pointing out was body integrity. This is the only area that differs from the regular Legacy line, so perhaps they found something is less reliable overtime to do with the moldings or the bed.
