I've got an 06 IS350 that I bought fairly used. It's got a little over 180k miles but has been very well taken care of so she still runs like a dream. A minor thing I have come to realize is that the auto on/off lights do not work. When I leave the car in auto mode, it thinks it is daytime all the time. I'm fairly certain that it is a problem with the sensor but I have no clue how to change it or see if it is really the case. Thought I would reach out to see if anyone else has had the same problem and how you fixed it.
