Vehicle was cleaned inside and outside (not engine) and would not start. Tried unhooking the battery and still turned over, but would not start. Waited 12 hours (overnight) - turned key on and received dashboard message to open and close driver's side window. Once that was complete vehicle started.

I assume this was some kind of immobilization feature, but would be nice to have information in the owner's manual on how to address it immediately! Luckily, this happened close to home.
