wannabe

I have a 2011 model and recently the car's electrics shutdown briefly while I was driving. There was a click and the cars nav screen closed and power went from radio, etc. As I was coasting fairly slowly at the time no harm was done, but I am concerned. Power came back about 2 seconds later of it's own accord. I haven't yet had time to take it to a dealer, but I thought I'd see if others have had the same experience.
