4,500 miles so far. I heard one squeak from the driver's window about a month ago and assumed I was having the window regulator problem, but I haven't heard the squeak since. Only other issue is with the NAV. For three months, voice recognition was fine... now I can't get it to correctly recognize anything. I make sure the fan speed is 2 or below and the windows are closed. I haven't changed my voice, so I have no clue as to why this happens. It's a little annoying to tell it "go home" and instead of plotting a route back home, it turns the radio on.
Beyond that, I love the car. Currently have 57 mpg on my tank with 200 miles on it... best I've ever gotten!
