I think its a bunch of garbage because first of all, you cant just use what you know today as a criteria for past actions. Thats kind of like practicing EX POST FACTO law. You have to use the information you know at that time and evaluate if the necessary actions taken at that time. Also, you cant just make a broad generalization. You have be specific because Toyota may have told certain owners that were directly impacted, but not others. Its not like Toyota will tell a Sienna minivan owner about a Camry safety issue. There is way more details than this and there is a lot of factors as well.
Any good company will do the right thing at the right time. Its lame people like that lawyer that blow stuff out of line. He probably just wants some revenge cuz he got laid off or something.
edit: Owner maintenance also plays a big factor as well. Not every problem can be blamed on the design when people dont care for their car. It can just be general maintenance. I suspect part of the problem lies within the owner's hands cuz for example, when my Toyota takes a longer distance than normal to stop, i get the brakes checked cuz it doesnt feel right. You cant just neglect your car and then blame the maker when you dont take care of it after all that use.
