replaced my battery and I still get it from time to time. I think it has to do with the steering wheel position, i think mine is offset just a bit. Just not worth going to the crappy dealerships in my area for a repair that's just annoying and not really effecting anything. I drive quite a bit on freeways mostly so still not really sure, def can't be the battery not recharging but i'll second brob that this is kinda ridiculous on such a high end vehicle.

 

Ok Check fluid level and top off if necessary (sue appropriate fluid)
Then do a reset for the active steering.
