Have you spoken to a lawyer about this issue?
Maybe you could set up a class action with every other scammed owner of this garbage system.
Also write to every single consumer rights protection association and to every single automotive media (magazines, websites, blogs, etc..), let the general public be aware of this issue and not just only Lexus thematic forums and owners clubs. General car enthusiast forums should be informed too if you want to make something happen, hopefully.
Make enough noise and eventually Lexus will do something in order to protect its reputation because in the end that's what every company in the world does: protect their affairs, not the customers.
