“The 1999 Lexus rx 300 transmission failed with only 125k miles on it. Based on the discussion boards, I believe that Lexus is covered up a design flaw in particular models. We as owners deserve to be confronted and Lexus should replace the transmission at no cost to customer. Infact Lexus should be penalized for not recalling the transmissions.”
