I have ordered a trim removal tool. How difficult is it to get the inside panel off the liftgate? I need to access the backup camera. I dont want to end up breaking a bunch of clips. 2013 C-max energi SEL. Thanks Gary

I knew a reset was required when changing the 12V battery. Information I received reading these forums. I told the dealer to do the reset and I sat in the parking lot after starting car, turning on radio and turning car off to see if I had a 10 minute timeout and I did. Whoever guy from Ford was he seemed a bit upset that the dealer had so little knowledge and he said a meeting between Ford and the dealer management was in order. I was never told code and Ford guy seemed to not want me to know either. He indicated the main code could be read by a Ford compat reader but the sub code could only be read by Dealer.. So much for transparent service operation. I have lost my faith in owning this car and must decide if a change is in order. For now its running great. Thanks for all the info.

Problem is fixed. Called Ford and gave them a hard time about the dealers around here being unable to repair my car. After a bit of excuses they said they would have someone call me who knows these Energi vehicles. Guy called dealer and got info from them on code and then he called me. He said take it to the dealer as they now know whats wrong and how to fix it. To verify his theory he had me measure the 12 V battery voltage which was down to 10.75 V. He said a failing battery can cause strange issues on the Energis. Dealer put in new 12 V battery and I have driven 200 miles and averaging 45-47 MPG in hybrid mode.

very interesting document. Thanks

Thanks for the info. I will get a scan tool and see if I can find what it is they are hiding from me. On my Energi, in EV Later drives like a hybrid. I see it switching back and forth from EV to ICE and many times a combination of both. You can drive it like a video game trying to keep the display blue (EV) as much as possible for a big jump in MPG by controlling how aggressive or light you work the accelerator. When all is well I often get over 50 MPG by driving it that way but average is about 45. When it acts up even going downhill or on flat ground there will be no EV switching but only ICE. When its working its fun to drive and I know the original owner as he lives in my neighborhood and we live in a gated community. He just drove the car to town for food and around the neighborhood. I saw it often and he said he had no issues. Its been garaged since new and inside and out look like a new car. He is 80 years old and like to use EV mode to country club to play golf. Energi in Auto runs some of the rechargeable battery and EV mode runs entirely off rechargeable battery. I have seen the problem in auto and EV later. Perhaps I can get the code and then complain to Ford and see if they can tell the dealer how to fix it. The dealers around here have hybrid trained mechanics but one told me all it was is a video course and not comprehensive. Again thanks for the info

Ford dealership will not tell me what the code is and I have asked many times. When they reset it the car runs fine but as soon as I start seeing only ICE and little or no EV and mileage takes a dump I know its come back. Its just simple, they have no one trained to work on these cars and the other dealers in the area when I talk to service managers are even more clueless. Electric and hybrid cars in this area have not caught on and with exception of prius (which is what I should have purchased) you see few on the road. When I purchased car I asked them if they knew how to work on such a technical vehicle and manager looked insulted and said we know how to service everything we sell. I will purchase a code reader as I have been a side line mechanic since 1969 and know how to use them. I would get rid of this car but I can not dump my problems on someone else so it just sits in the driveway and I run my old Honda. Plus this problem is most likely covered under warranty. I only know it is a controller fault which is all I could get out of dealer. Said it was controller that manages hybrid modes. I really doubt I will get it fixed so I have a nice yard ornament. Even if I can pull the code they most likely wont know what to do about it. Sorry for being touchy but forums like these have fan boys who will never admit the cars or dealers could ever be at fault. Thanks

Problem we have is the dealer does not understand this car and makes shot in the dark diagnosis. They admit my car is the only one like it the dealership has worked on. There are no other dealers within an hour from me and talking to their service manager they dont know how to work on it either. I have never seen another one of these cars on the road in this area. I have a repeating controller error code being set which I only found after taking it to a hybrid shop in the area that are well known experts and hybrids and battery cars. The code it sets they can read but they cant access the sub code needed to identify the issue. Ford dealer just resets the code and says there is no problem. When it acts up I get greatly reduced mileage (over 10 MPG) and as I drive I see mostly engine running and rarely on battery running in EV later mode. Even though you assume I am stupid and dont know how to run the car. The stupid ones are the dealer that cant fix a car they sold me and charge me every time they do nothing. Calls to Ford have done me no good.

Car only has 47000 miles. My Honda has 155K and only needs routine service.

I found it myself. I have not driven the car except around the neighborhood because every time I drive it further it costs me another $300 dealer visit. I had not changed the time in the car when the time changed and it looks like if the cars time doesnt match the time on computer running the app it does strange things.

I monitor my 2013 C-max charging with the online software. It always finishes on or before the projected charge complete time. The last two charges it has gone an hour past the charge time and when the light ring around the charge port finally went off when I un plugged it I got an error saying charging was interrupted by being unplugged while still charging. I just tried again and its way pas projected time and has not finished. The 120 volt charger has a green light so not showing a charger error. This car has lived at the dealer and I am ready to run it off a cliff. I have only driven it 5000 miles and have 10 dealer visits for numerous problems. Any ideas?

What scan tool will work with my 2013 C-Max Energi. I would like to monitor battery charge and error codes. Is there a specific reader that will work best with this vehicle? Gary
