 I was one of first in my area to purchase this model.  For the first 18 months it was a great car, although the display needed to be replaced.  Then it broke down on me (computer failure) at 18 months (15,000 miles).  The computer was replaced, and immediately my MPG went down significantly.  My 54 MPG highway went to 44 MPG highway for the same route (same seasonal temperature).  My local MPG went from 41 to 35 MPG. Dealer thought the software recall/upgrade would help but it has not.   Others seem to report this problem.  Dealer has not offered any solutions. Aside from these problems, I have enjoyed this car, but I want my great MPG back!
