If you have an early build vehicle, be weary of the rear window defroster issue. We have had two local cars (both Launch Editions) shatter within days of each other, and both were checked under TSB 23-019-014 and said to be okay. In both cases, the phone slid forward and hit the defroster button unintentionally. It may be a good idea to pull your defroster fuse until a resolution is found, and save yourself the possible paint damage and cuts on your hand. This would only apply to the early build 2013 cars, 2014+ owners don't need to worry apparently.
