I see this problem more and more on Lexus vehicles , I believe it is a Lexus problem, from a company who praises their engineering expertise so much, I cant understand why that can't make a sun visor that will stays up. Maybe they should consult with the engineers at Yugo or Hyundai-the same year cars don't have this problem. I am writing to Lexus Headquarters -19001 S. Western Ave, Torrance, CA 90509 800-255-3984. I think they should replace them free of charge, a replacement part cost $267.00, not including installation
