I'll agree about the 2013 US C-Max, I can unlock the doors by touching the back door handles. I've not really tested it, but opening the back hatch hasn't seemed to unlock the other doors.

Release latch?  I have no idea.

I was simply responding to a claim that pulling the rear handle unlocked the doors.  Not true on my '13.

 

Correct me if I am wrong, but the Canadian and U.S. models are identical save for the FT daytime running lights on ours.

From the '13 Manual:

 

Intelligent Access (If Equipped)

The system uses a radio frequency signal to communicate with your

vehicle and authorize your vehicle to unlock when one of the following

conditions is met:

You touch the inside of the front exterior door handle.

You press the luggage compartment button.

You press a button on the transmitter.

 

I don't believe the rear door handles have sensors.

Correct, opening the hatch does not unlock the doors only the hatch, I edited my post above for clarity.

That's what the manual says (see my post 6 above) but touching the rear door handles unlocks all doors on my 2013 SEL.

Looks like they made a change to the Job 2 or Job 3 2013 C-Max. Not surprising, since the sensor would be expensive, and deleting it would same money and complexity.

I've got a 2013 and you definitely can't unlock the doors by pulling the rear passenger door handles. 

 

With FOB in pocket I can unlock my 2013 SEL by the front and rear door handles ... Build date is Nov. 2012.

Porter's build date is 29092013. All driver's side door handles will unlock the car intermittently. They seem to know when it's cold and windy. (Can't say about passenger side.)

 

There's a TSB on the driver's door, but it's been done twice to no effect. Third time, it didn't malfunction for the tech, even though I demonstrated the problem to the SA. When the driver's door malfunctioned, I got used to grabbing the back door handle to unlock.

 

Then the back door started malfunctioning... intermittently, of course.

 

Have fun,

Frank

As I stated, the rear passenger doors do have the sensor to unlock on my 2013 C-Max. My build date per Etis is 02.06.2013 (2 Jun 2013), not sure when Job 1 production ended.

You sure you have a '13?  A build date of June '13 would be a '14 model, no?

I have no idea when they switched from building 2013s to 2014s but mine is a 2013. I suppose it could be another of those strange etis issues. Additionally, I can unlock the doors by touching a rear door handle -- which the 2014s couldn't do.

 

Wasn't the 2014 C-Max not available until late in the year (November or December)? It is possible that they didn't switch over to building the 2014 C-Max until later in the summer.

My '13 SEL was built in November of '12 which would suggest the rear handle sensors were added in later '13 models but then dropped in the '14 models. 

Very strange....

Maybe not in Canada.  :)

 

With FOB in pocket I can unlock my 2013 SEL by the front and rear door handles and by pushing the release latch under the hatch handle, the rear hatch unlocks but not the doors.  Build date is Nov. 2012.

 

Agreed.

 

I think part of the problem is semantics.  In my view, the rear hatch doesn't really have a lock as do the doors.  Ii's more of an electric latch which is activated from under the hatch handle.

 

As an aside, this is why having jumper cables stored in the rear is a bad idea.  The rear hatch cannot be opened when the 12V battery is dead.  At least not on 2013 models.

 

 

Cheers.

It seems like jumper cables would fit well under the driver's seat, in the compartment where the charging cable is stored in the Energi.

What about in that cavern under the armrest?   You could probably fit a small dog in there.

 

But seriously......with a dead battery, you can't open the hatch with the metal key in the FOB?  Doesn't the NHTSA insist on a manual unlock option in the rare event that kids/animals/your mother-in-law gets locked in there?

That's where I store them in my Hybrid.

No, you just have intermittent or non-functional sensors in your rear handles.

 

I assure you they were present in at least one car built 19.9.2012. Intermittent operation, as I've reported, is far more likely than random feature deletion. Like I said, it's the backup to the front handle that's always malfunctioning half of the year (been fine the last few months... wait, it's summertime!)

 

Have fun,

Frank

Sacre bleu----I got the year wrong.  Car was born in November, 2013.

 

I can assure you, as I sit here living and breathing, and having inspected the car in the bright September sunshine, that the driver's handle has a sensor, about 1/2" x 1/2", and the rear passenger door has none.

Here's the control diagram for the keyless entry with push button start and a pic of the rear door handle showing the electrical circuit to the handle (front handle is similar) from the 2013 workshop manual.  Also, I can't visually see sensors under any of the door handles but obviously the sensors are there as touching the door handles unlock the car.  The RF antenna enable the keyless entry key FOB to be validated.  The hatch unlock evidently does not have a sensor.

Didn't "Build 2" start in about August 2013?  That may be why yours is missing this function.  Mine built Jan 2013 has the rear door sensors.
