 Update November 2016:  at approximately 160,000 miles the CMax energi started making a "whiring" sound during deceleration. Turns out bad transmission. $7000 to replace and Edmunds value of this 3-year old high mileage car is only $5000.  Quite a wake-up, my cost per mile for ownership of this car is now shot.  Many other better values out thereUpdate May 2016:  So almost 3- years of ownership and well over 150K miles. Car has never been in the shop except to replace the 12V "starting battery" for $140.  All I have done to this car is rotate tires and change fluids. Typically 15,000-18,000 miles between oil changes.  I am getting a little wind noise from one of the rear doors, I think it's the seal. Other than that the car has been flawless.Original post:  I purchased my Energi in August 2013.So far the car has been flawless other than some bugs in the "Sync" system that have been fixed by a software update.I typically drive 200 miles per day on Southern California freeways commuting to various construction sites.I often drive into Los Angeles, the deserts and mountains for work.This car is very comfortable at freeway speeds, where I drive with the flow of traffic, often 80 mph.At the speeds I drive and distances between charges, I am very happy with my 42+ mpg.I am by no means a hyper-miler, and I carry hundreds of pounds of gear in the car every day.
