I recently purchased a Lexus Rx350 and I totally regret it! I have had nothing but problems with the acceleration and although all the technicians that have driven the car agree there is something wrong, they can't do anything to fix it. I was told that until enough customers complain, there won't be a software fix. C'mon Lexus! 60K car and it drives like crap! Sadly disappointed and first and last time Lexus buyer!
