The build date should be at the top of the sticker with a number like 120130201.  Ignore the first number.  The next four are the year, then month, then day of month.  So this code would be a build date 2/1/2013.

My sticker doesn't have the white parts with numbers on the top or the bottom.

Thanks for the link.  My car was built in late January of this year.  Two dead batteries in the first two months of life.

Using the code mine was built 9-23-2012.  It sits at the dealers with the dead battery right next to Andrew's C-Max.

C Max is in the shop so I can't give you build date, etc.    Dead battery three times so far, always when parked in garage overnight.   Dealer replaced 12v battery about 2 weeks ago but vehicle was dead again yesterday.  6k miles on vehicle.

 

I have heard a noise several times behind the passenger side rear wheel.  It sounds like the cooling fan for the lithium ion battery or a fuel pump running. This was with a cold car  sitting in the garage and I just happened to walk by and catch the hum.

 

What module controls the cooling fan and can it start/run independent of everything else?

 

Dealer is clueless.

Mine was built 9-17-2012 and no battery problems at all in almost 5000 miles. Mine is a SEL.

I purchased my Cmax on 11/01/12. Except for trips, the car is always garaged and I check nightly for any lights etc. which may be on in my pitch-black garage.
 
Failure 1, on 11/08/12 with mileage of 998: Completely Dead, no lights, nothing came on. Called Ford Road Service, got jump. Not taken to dealer, as I was in the middle (Winslow Az) of a road trip from San Diego to Texas for the USGP.
 
Failure 2, on 01/19/13 with mileage of 4359: Completely Dead again. Called Ford Road Service, got jump. Took to dealer, battery replaced.
 
Failure 3, on 02/26 with mileage of approximately 4980: Completely Dead again. Called Ford Road Service, got jump. Not taken to dealer.
 
Failure 4, on 03/02 with mileage of 5050: Completely Dead again. Called Ford Road Service, got jump. Took to dealer, no draw found. After keeping the car for several days, the agency couldn't duplicate the failure. 
 
So I am still waiting for a fix.

New,

  Leased from Kemp Ford in Thousand Oaks Jan 15, 2013.

Dead battery on morning of Mar 10. AAA jumped after battery reading of about 6 volts.

Called dealer and took in on the 11th. Kept overnight and called next day and said they couldn't find anything wrong.

Interestingly, when I took it in the 1st service manager said he had not heard of any problems. The 2nd SM came in and

said this was the 2nd one with this problem. Supposedly the first one was fixed by replacing the "door electrics".

 Also Oxnard (member) and andrewwx... I also was at Vista for a test drive, and they had to jump start the C-max

 In the test results from Kemp there was a service message that recommended not having maximum electrical loads for short

drive cycles. (laptops and DVD players) Also of interest was a lady at the dealership that told my wife that her hubby drove hybrids

a lot, and he says to us the brakes a lot to keep the battery charged.

Just pick-up our C-max from the dealer tonight.

LOL when the car delivery guy took us outside to give us our car.

It wouldn't even turn over, dash light didn't even go on.

Guy was like hummm, i tell him, this seems to be an on going problem with these cars.

He says, we have only sold 2, so we haven't heard about it.

We go inside, and the manager says, lets boost it and see. 

It started right up.  

Car had only 50 miles, and had been sitting in a dealer lot in Ontario, and had been trucker to my dealer in Quebec this week for us, since these babies aren't stocked much yet. 

So probably since these batteries are weak, it needs a charge.

I told him, i would give it a chance, and let them know.

 

All seems find, we did another 50m tonight.

Had 12.3v when i got home.

Put on my trickle charger tonight to bring her back up

Nearly identical to my situation Edman.  My car died on day two of having it home with 60 miles or so on it.

 

I could tell from the terminals that it had been jumped before.

 

I am not having nearly the same problems with low battery after fully charging it on the trickle charger.  I've also bought an inexpensive solar charger that I leave continuously plugged in to the cargo port.

From Ohio

 

I picked up my CMax from the service department after three dead battery situations.  Dealer found numerous error codes in 5 or 6 of the control modules (mainly related to loss of voltage).  They reprogrammed every one of them including the engine control module.  I asked the to check for service bulletins so they checked Ford's site where service info is shared between service departments and reported new 12v batteries and reprogramming seems to be working.

 

Here's the interesting part.  After driving it about a mile I noticed a distinct improvement in dash reported mpg.  My car had slipped to about 36 mpg prior to service and is now running at a dash reported 41 mpg after several hundred miles.

 

I'm not complaining.....

So do we (Ford) have a fix?  This news from Ohio looks like a possibility to me.

I'm skeptical because I don't think that control modules would/could be reprogrammed to clear error codes.

I'm betting they just found 5 or 6 error codes being reported and reset them all, which would fix nothing.

But without more technical detail, I'm just guessing.

Called the dealer today.  Been in a month.  He asked me if my "ears were burning?"  Because he said he just got a software update and the tech was installing it now and I could pick up my car today.  Hope the problem is fixed?  I told him I would pick it up tomorrow.  Let's see if it starts then! LOL!
