We had no reservations leaving our RX450h for 2.5 weeks at the airport parking lot. No issues whatsoever.

Default Intermittent start up issues with RX450H

I have a 2013 RX 450H and when trying to start first thing in the morning the ready light does not come on. BSI indicator lights up as well. I have replaced the battery in the faub but still have issues with initial start up. After several attempts of turning off the lights in dashboard, I try the start button again and the ready light comes on and she is good to go. Does anyone have any ideas what this issue could be?

Check couple of things:
Does the gear display show P or N in the display [try jiggling the shift lever and see that display remains solidly in P or N.
Have an assistant stand behind the RX and when you apply the brake, does the assistant see the brake lights light up.

Additionally, when you put your foot on the brake, does the green light on the start button come on? If not:
a) make sure your fob is not right beside your phone in your pocket, that can scramble the signal.
b) hold fob directly in front of the start button and see if the green light comes on, before pressing the start button
