Drove the C-Max to the grocery store and back yesterday morning. At 7pm I found the car completely dead. The 12-volt battery was completely discharged. I put the charger on it and the car came back to life and it was okay this morning. There are a HUGE number of posts on fordcmaxhybridforum.com about this problem. I'm going to have the dealer do TSB 13-5-1 which changes how the DC/DC charges the 12v battery. While there I'll also have them apply the TSB that fixes the "i need more than one kick to open the rear hatch" problem.

I have not had the battery issue but I tried to get the dealer to apply the TSB as preventative measure. The dealers take, which is usually the same one I take, is if it ain't broke don't fix it.

They did apply the lift gate TSB and it definitely has worked first kick every time since.

Moral of story: If you want the TSB, without the possibility of the dealer pushing back, you need to tell them you experienced the problem.

Sorry to hear of your dead battery, especially since it's in an Energi.  Do you know what the build date of yours was.  Without the DCDC charge rate fix, there is some risk with short trips it appears, but I think a 12v battery of sufficient capacity should be able to handle it.  In the case of the C-Max though, I'm thinking the battery capacity is just a bit too low.

Thanks for the dealer tip Don. I'm in no rush, but will insist they apply all 3 TSBs when I go in.

I want this car. I went to a Ford dealership in Fairfield, CA, and EVERY SINGLE C-Max ENERGI ON THE LOT WAS DEAD. He couldn't open the hatch on any car in the lot. When I expressed my concern about this, he said someone was test driving them yesterday (ALL of them?) and must have left electricals on. Sounded fishy to me but I think I still want the car, figuring whatever the problem is, they're going to fix it. However, he failed to send me a comparison of lease v. purchase plus an offer for my trade-in, as promised, and he won't respond to my emails or phone calls. Who ever heard of a car salesman who doesn't want to sell a car??? What's going on here, do you think?

I think you happened upon a lying, incompetent salesman, who you should not use under any circumstances to buy a car.  There's nothing to be "left on" that could drain the battery.  It's likely they have not been driven enough to keep the battery charged, but rather short trips that resulted in a net drain on the batteries.  How many Energi's was that anyway?

 

BTW, opening the hatch requires the car to be unlocked or the key to be on the person opening it.  Could it be he was incompetent in assuring one or both of those were done too?

Welcome Curleegirl!   I'm a new owner, and so far very happy with my purchase, as I think the vast majority of the folks on the forum are.

 

Regarding the dead batteries, AZenergi's remarks were right on.  In particular, the fact that ALL were "dead" suggests the problem was the salesman's in not knowing the proper procedure to open them, as AZenergi pointed out.

 

Regarding the salesman being unresponsive and apparently uninterested in selling the car - well as counter-intuitive as that seems, it was my experience as well.  I contacted about 7 dealers in my state, beyond my local dealer, and three did not even respond to emails and phone calls. At all. One other gave a ridiculously high price and would not budge even after I presented documentation of better prices and walked away. One other was slow to respond. The final two were helpful and reasonably knowledgeable and willing to negotiate.

 

There is a thread something like "do dealers want to sell these or not?"  I don't understand it, but there's a huge range in sales people and their interest in selling a car. As AZenergi noted, this salesman seems to be one to avoid for sure.

 

You might check in the regional section and other posts in buying to try to find what dealer in your area others have used and found reasonable.

 

Good luck!

I see the Ford dealer in Fairfield may have 6-13 Energi's.  Did your salesman try to open the hatchs on all 13?

Curleegirl,

 

If you are still looking for a good sales person (integrity is important) I would like to suggest Dave Elkins at Fremont Ford. 

I would not hesitate to send my mom to him to buy a car.  As with any car purchase, you best friend is knowledge!

When my car showed up at the dealership (Special Order  X-Plan) Dave pointed out cosmetic flaws and made sure

they were fixed. If he doesn't know an answer to a question, there is no BS, he goes and finds the answer!

I suspect 1-post Curleegirl was not a serious poster, and has little interest in the c-max.

Well, my Energi was dead this morning. I ended up driving my truck to work.

The hatch won't even open. How can you get to the battery without opening the hatch?

There are battery charge points under the front hood, or a 12v source could be plugged into the rear outlet.

Good luck and let us know what caused it - if you ever find out.

Ok, I was too concerned about getting to work to give it much thought. I have a call in to the dealer, but I'll jump it when I get home.

This definitely looks like a very, very common problem from what I've read here and on the regular C-Max Hybrid Forum.

 

The bad news is this didn't show up until just now. I've had the car since Feb 2nd. That means whatever the failure mode is, it can occur at any time.

Ouch, sorry to hear that, rtshinn.

 

There is a TSB out there to change the software that controls how the 12v battery is charged. I'm surprised it was not part of our most recent set of updates for the MFT and liftgate. Ask the dealer to look it up.

 

But in general, we should all make sure we have some form of jumper cables or jumper battery onboard, given how people keep getting surprised by this.

I ordered one of those Stanley Simple Starter thingies that others have, from Amazon. Will keep it in the car.

How do you like your Stanley Simple Starter?

 

My 12v battery died Saturday, called Ford Roadside Assistance but got a friend to jump the car before the assistance arrived.

 

I left the rear hatch open all day, I think it drained the battery. How nice of MFM to text me saying my 12v battery was dead. Would have been nicer to get a 30 minute warning...

I've had my Energi for only a week and found it dead when I went to start.  No power whatsover.  Called Ford assisted who boosted it and it started right away.  I dropped by the dealer and they said I might have left the lights in the always on position.  It is possible.  Would have thought that it would have turned off on its own after some time but perhaps not.  Will monitor and see how it goes.

Headlights do turn off on their own...when the 12v battery dies. ;-)

How often did you run down your 12volt battery on you last car? Probably never. This is a problem with 2013 Ford Hybrids and Energy models. It is not "operator error". Your dealer should know better. Even my Ford dispatched tow truck driver was familiar with the problem. There is a circuit drain (one or more). I am confident Ford is working on a fix! Blaming the customer is unfair! I test my battery frequently. The voltage is typically bellow standard after a couple of hours after a drive. There is often a significant drop overnight (11.9 - 12.3 range. The concern starts bellow 12.4). It's not you!
