Just started to have this issue over the last few days. Turning the ignition on and off will sometimes bring it back, but over the last four drives I have taken, it has failed to function on three of them. No clue when I have time to get to the dealership (especially since I am worried of another 2 week span without my car), but the annoyance of this should make it pretty soon.
