06 IS 250 ; put foot on brake ,press start button , nothing happens , car doesn't turn over . Brake pedal does not depress as it should when starting car , Dealer doesn't have a clue , checked computer and said it is fine .

The problem with the lexus is 250 (and some other lexus models) is the starter switch itself. The starter button needs to be replaced ! There is a Lexus technical service bulletin out on this. Lexus seems to be downplaying it. They won't replace the starter button until they can duplicate the problem on your specific vehicle. Long story , but DEMAND that they replace it . You will get stuck somewhere !! At this point there has not been a recall on this defect. Good Luck . Oh yeah, when Lexus puts the car on the diagnostic computer in your car , this problem does not appear ! The problem with the lexus is 250 (and some other lexus models) is the starter switch itself.
