Thanks for all your answers to my questions. I asked both the service man and the new car man and neither was aware of any changes from year to year concerning these two models. I combined all of your questions in one post below: my driving pattern is virtually the same. The battery charge now occurs when I would say "coasting" meaning not accelerating at any speed. It also occurs at the time of braking as it used to. It has not ever reached full charge ever as yet while the other car a full charge occurred regularly. Since this is a brand new car and the other one was too when leased. I really didn't notice a break in period in the first car. I was getting 42 mpgfirst cmax sel was a new 2015 leased vehicle. this is a brand new 2017 titanium. After a 2 year lease the mileage reached 10000 miles at turn in. the new car has not reached 2000 after about 5 months of driving.tire pressures where just checked when the car was taken for the first check up The mileage has begun to creep up, but until very recently it was 30mph. now I believe I get about 38. I have noticed that while driving, the indicators stay in the white zone longer than in the blue on the dash indicators. I really have never understood what these indicators mean so maybe that will tell me something if understood. you can see I am not very informed on the car but this being the second same model I am aware of the differences.
