We just bought the 2006 LS430 about 3 months. The car fails to start twice in two weeks with the keyless in or out of the ignition. A message "check S/T lock" even the steering is not locked when the key is inserted into the ignition. The car finally starts the following day without any problem. The car was checked by the Lexus service. However, there is no problem found. Please let me know if you experience any similar problem or this is due to operational error. Thanks,
