VAbluecmax

39.5 mpg with 2060 miles. Car came with 660 miles on it & a 19 mpg lifetime. I wish I had reset it then but didn't know I could. I may reset it with my next tank of gas - whenever that is! :)

Yes, I would still buy it. After more than 6 months of wanting a C-Max and deciding not to get it because of all the questions about gas mileage, I decided that I'd be happy with 40 mpg and bought a C-Max in early July. Just got my 3rd tank of gas and my mpg is 40.2 (1st 2 - 37.4 & 38.3) - I am very happy with the upward trend and feel confident that I will reach mid to upper 40's as the engine gets broken in. I also think I'll be joining the 500 mile club in the next tank or two! :)

Second time's the charm for update 13B07 - I had a couple of updates 2 weeks ago but the car couldn't go into electric above 62 so I figured that the new update hadn't been released. After reading of everyone's experiences here, I checked my paperwork and they had installed 13B07 so I called and made an appt for them to try again. It worked perfectly and I took it on the freeway and was able to get it into electric mode at 80 mph (sorry, no pictures! :) ) I'll have to see if the warm-up time is shorter tomorrow morning.

Hello wab - I'm sure you're right that changing the odometer is still against the law! I'm curious about whether as part of the sw updates, there is any way that the odometer can be fooled into thinking the car has been driven. I really don't think this is possible but am bending over backward to try to understand how 17 miles appeared on my car when the dealership swears they didn't drive it. I certainly understand the need to test drive a vehicle - I just want to know about it!

Hey Adair - I don't think the odometer can change with a car sitting still either but this was one of the explanations I was offered by the dealership's mgmt - I'm realizing that I'm driving a computer almost as much as a car and don't know if updating the "operating system" can impact the odometer.... I've been hyper- focused about my mileage because my c-max came with 660 miles already on it so I've been mentally subtracting that to know when I passed my "first 100, 2nd hundred, etc". Thank you for your quick response!

Hello Adair - I have a question about the 13B07 update related to what you observed: "The MPGs were 45.2, down from the 47.2 I left it with. (I know, they ran it for 2 hours while they tested it, plus who knows what else while it was there)" If running the car can drop the mpgs, can it also change the odometer settings? I'm trying to understand what happened with my c-max last week. I had both the 13B06 (rear gate trunk module reprogram) and the 13B07 updates applied last week while I was having mudflaps installed and when I picked the car up, I thought it had been driven - there were 17 unexplained miles on it (I was assured that none of the techs had driven it) my mpgs had dropped from 38.9 to 38,3 and all of my display settings and the power seat settings had reverted back to the factory defaults. BTW, I have noticed that since the reprogramming, the car goes into ev faster and stays in ev longer on inclines and small hills and the MPG tenths do change faster (unfortunately, they drop faster for me as well! :))
