I think you need to go back to the dealer and explain what is going on or better yet go to another dealer. I have driven a few rx350s and they ride great. If you don't like it get rid of it and get something you like. But I do agree with CD that it is immature to say you hate Lexus? If you want help with a problem there are loads of people here who will help you. But not when you post the way you have.
