Reading through the posts here (and on any model-specific auto forum, for that matter), one would be inclined to deduce that owners of C-Max cars are beset with nonstop problems and endless trips to the dealer. Doing research on a car by reading forums dedicated to it slews the overall picture, because the people most likely to post messages are those people who have problems. People who don't have problems, typically don't post messages about their cars.
So I'm just here to say, I now have 3300 miles on my C-Max Energi, I'm 3/4 way through my second tank of gas, I've been driving it since I got it in July, so 2 1/2 months. I've had a total of ZERO problems of any kind. The car is perfect. I love it!
