I have had this car for a little over a week. My wife has had a civic hybrid for over 2 1/2 years. Never had a problem so I decided to trade in my crv. I have 1000 miles on it so far. My mileage has been pretty consistent 50 /51 mpg. I don't do a lot of city driving. so I will have to wait and see. It is a very quite smooth runing car.
