A new behavior has cropped up at ~30k on my 400h. While sitting in the car with the ignition in ACC postion (or so I thought, more on this later) the radio would cut out the dash would ficker, the NAV screen would flash the "Lexus" logo with sounds of relays switching somewhere behind the front seats. When I turn the ignition to OFF and try to start the car it will not go to READY and displays the error that I"m not in Park "Shift to Park (P) to start the car", but the shifter is in Park. I even tried wiggling it. It seems if I hold key over inthe START position for long enough the system will boot to READY, but I fear the day when this trick doesn't work. The other thing I've noticed is that the detent in the ignition switch to indicate the ACC position is notched and there are actually (2) detents right next to each other that both seem to function as the ACC postion. But I suspect that the right most detent, which is the first one it drops into when switching from ON to ACC (CCW rotation), is a false ACC postion and that some king of short is occuring that drains the 12V battey to the point where the system cannot remain booted. Does any of this make sense to anyone? Do I just need a new ignition swich of does everyone have the "false ACC" detent and is something else wrong?
