 Knock on wood when I am writing this but I STILL LOVE MY C-MAX!  I have 2.5 years and 33,000 miles on it.  It is peppy and good to go.  I get great gas milage despite my lead foot.  Only issues have been recalls but those are the same as most cars (software updates and the airbag recalls that everyone has had).  The dealer did a good job at getting me in and out for those minor issues.  No mechanical issues.  Reliable.  And did I say it GOES!  Not your normal hybrid.  Very happy with my car!
