We just purchased a 2011 Lexus Rx450H, all 4 windows opened twice even though no one was in the car. Anyone see this problem? Could not make it repeat.

Most likely you accidentally held down the unlock button on your key fob.

Try resetting the BCM to see if the windows behave.

Might just need to reset the power window module…

Different issue but might work for you if resetting the BCM as Tester said doesn’t work…
