This just happend to me yesterday. spent 4 hours at the dealership.  Luckily I have an extended warranty and it only cost me $100.00. Car has 43000 miles on it.  At 35000 the differential ( I think ) cracked that was two days in the shop.   
And the SD card in the navigation system said it had a "fault", plus the reverse sensoring system wasn't working correctly..   
  
This is my second edge.  my first was a 2007. Had over 100,000 miles on it ...never a problem.  Got rid of it because I figured things were going to start going wrong.  But this car that I have now is way too new for the problems that it has had.
