Stats:

2014 C-Max Energi

21,000 miles

Not sure of build date (where do I find that?)

 

Situation:

Drove to relative's house 200 miles away for Christmas.

10 degrees outside. Did not plug car in.

When we started to pack the car to leave, the liftgate wouldn't open easily.

Got in car to start it, and no sign of life. Screen said "System shutting down to save battery."

No warnings at all via MFM. None.

Turned off all possible functions in car. Waited a few minutes, and car started.

 

Plugged car in upon arriving home. Stayed plugged in for 2 days.

Tried to start it; same issue as before. Plugged it back in for a minute (I had unplugged it as usual to start it), sat in the car with dash activated, unplugged the car, and it started right up.

 

 

Questions:

1. I know there's another thread or two about this issue. Given the age and mileage of my car, is it likely that the battery is truly dead, or should I look for a different root cause?

 

2. Someone remind me...how can I check the battery capacity without a voltmeter? Something about starting it while pressing the OK button????

 

 

As a side note: on another thread, someone indicated that if left running and you exit the car with the key, the car will shut off after 15 minutes. I can tell you this did not happen for me (and I'm glad it didn't). I left the car running for 2 hours while I was inside an Urgent Care clinic (because I was in a bind and did not trust the car to restart), and I came back out and it was still on, silently. 

 

Thanks in advance for your help/advice.

Update: I just tried to start it again for the heck of it. When I unplug it then open the door, there's no sign of life. But when I plug it back in and open the door, all of the dashboard lights come on; at that point, I am able to unplug and start the car. But the check engine light comes on, so there's clearly some sort of issue.

 

There are no available appointments at the dealer until next Wednesday (six days from now). If y'all think this is purely a battery swap issue, then can I just take it anywhere? Or should I wait and have it looked at by the dealer? (It's still under warranty.)

 

Thanks!

Do you have a 12v battery hanging around somewhere?  I know its not likely but a thought.  

 

If you can get one and make a plug for it, you can do this:

Look at post #53.  This way you'll be running an external 12v battery in addition to the internal one.  If this fixes your problem, then you can take it to the dealer or any place at your convenience to get the battery under the trunk area swapped out.

 

That car does weird stuff when the 12v battery is dying, so fix the obvious first and then see what issues are left if any, so in other words ignore the check engine light for now.

Nope. No 12v battery sitting around. 

 

But wait a second...what's the "battery under the trunk area"?

Under there is where the car's 12v battery is kept, behind where the funnel for the gas is.

Yeah...I just figured that out. Wow. This confirms that I will not be changing the battery myself.

Absolutely not, its a pain in the butt to do.  I'm even reluctant to do mine when I need to.  My original lasted all 4 years no problem, my new 2017 should last at least that long if not more.

In the OP you asked where to find the build date - it's on the VIN plate in the driver's door jamb.
