Absolutely! I'm thinking/hoping that they applied the 13B07 upgrade along with several others that should have been done at a previous dealer. It's almost like I have a new and improved C-max!

Alright, so I picked my car up from the service department a few days ago and all seems well. It was an interesting experience to say the least. When I first dropped it off I told the SA everything that was happening. I also mentioned that my vehicle wasn't going into EV mode about 60 mph and wondered if the 13B07 update needed to be applied. The SA looked up the vehicle's history (I had only owned it for 3 weeks prior to this point) and told me that the 13B07 update had already been completed. I enumerated the other problems I was having with it and also that the SYNC system needed updated. This is where things get kind of interesting. The same SA calls me back a few days later and explains to be that once there technician looked at the vehicle, he discovered that all the updates/installs the previous dealer had listed as having done, were NOT done at all. In fact, it took them a couple of days to update everything. They also said the 12V battery was bad and had to be replaced. They would not give me a list of codes, but I know they did update the SYNC and now my car will go into EV mode even at 70mph so I am assuming that a 13B07 was updated. As far as the other codes or problems, I still don't know but they attributed much of it to being a bad battery.

Hey golfer, thanks for the reply! I ran a VHR and it reports no problems other than a factory restraint recall and a sync update. I checked on the Ford Etis website and only found a 12m02, 14s04, and 14b03. An apim issue with the sync, the factory restraint recall, and the fuel economy costumer satisfaction. None of it seems related to the issues I've been having. When I get it in to the shop I'll keep you posted with what the dealer tells me. Thanks for the help!

Alright, hopefully I'm not alone with this and someone can shed some insight. I recently purchased my used 2013 C-max SEL from a reputable dealer and LOVE it. I drove it off the lot with 23k miles on it and I was getting great gas mileage... However, I have recently been having problems with it being difficult to start (i know, common problem) but lately it's been giving me all sorts of errors from service advanceTrac to power-train malfunction (the amber wrench icon) and sometimes when I let of the accelerator, instead to coasting it immediately slows to a stop (it feels like driving the car through wet sand.) I think it's the regenerative breaking somehow applying but I'm not sure. During these times I cannot get into EV mode no matter what I do and the car gets absolutely TERRIBLE gas mileage. It's still under warranty so I'm taking it in Friday, but I am getting a little disappointed in this car that I absolutely dig. Any advice?

Where exactly did you place the heaters? I'm very interested in doing similar with my car since I have to leave it outdoors when I'm at work.

So I know it's a little early for this, but does anyone have any experience or recommendations for aftermarket engine block heaters? Also, seeing how cold temps take their toll on the HV battery, and thus MPGs, would it be possible to outfit the big battery with an external heater/warmer? Any ideas?
