After our initial dead battery incident, Fords' inability to diagnose the root cause of the problem and while awaiting Fords' forthcoming epiphany concerning this issue I have come to the conclusion that our SE is a de facto plug-in version of a C-Max SE. To address this anomaly when the car is parked in the garage it is on a Battery Tender and when on the road I carry a portable jump start battery. This way I hope to eliminate any more undesirable "surprises" ;)

Since my dead battery incident if I need to use the car the next day I put it on a battery tender. I have a number of vehicles and when not being run for a week or more I keep battery tenders on each. After running these vehicles and hooking up the battery tender in less than half an hour I get a green light (battery fully charged). Not so with the C-Max. It has taken a minimum of 6 hours each time to get a green light. Not sure of the significance, but I do find it odd that the only vehicle I own that has a battery problem exhibits this phenomenon.

Since taking delivery of my C-Max early in April I checked the at rest battery voltage each morning before running the car. It was always right around 12v. After the dead battery incident where Ford checked the car out per the Ford hotline recommendations (and found nothing wrong) the last two mornings the at rest voltage has been 12.8v. I hope this continues - I will keep monitoring to see what happens.

Yes, the battery tested "good" according to their diagnostics so they recharged it. I was told that "a complementary charge" was all that Ford will offer if their test shows the battery is rechargable. Immediately after shutdown I show 13.12v. By the next morning its right at 12.0v - that is until the car went dead last Saturday night.

Picked up my 2014 SE from the dealer today. They had it for 4 days. They had contacted Ford's Hotline and followed their instructions for testing. There were no outstanding TSBS for my build date (3/14). A number of looms and inline connectors were inspected, coolant pump was checked. Apparently the car was connected to an electrical system monitor because they list a .010 amp drain and that 2 to 3 times an hour it recorded a .300 amp drain lasting 10 to 14 seconds which Ford engineering said was the BCM waking up momentarily - a normal operation. Apparently the car was monitored over an extended period of time because the tech mentions overnight current drain results. So, at this point they were not able to find any problem other than the dead battery it came in with :-(. Now it's off to the body shop to get the front end ding repaired.

This is my first post concerning the Dead Battery Issue on my 2014 SE (build date 03/14). Car delivered 4/3/14. Battery found dead overnight 4/12/14. Battery voltage was 6.9v. I had been monitoring overnight voltage each morning and it was running just below 12 volts. Since the dead battery occured on a Sunday (dealer not open) I monitored the voltage as it dropped during the day down to 4.7v Sunday evening. By Monday morning the voltage was 2.7v. Had the car towed to the dealer. It has been there for 3 days. They can find nothing wrong (as usual) other than the battery was dead. I figure I might as well get the papertrail started. Service Advisor did not seem up to speed on this issue. Thought there was only a problem with bad batteries on the 2013's. As I explained the problem he commented that I was more up to speed on this issue than he was (go figure!!). Told him it might be a good idea for him to call the Ford Hotline!! I can see this is going to be a long road ahead. I waited to order a 2014 hoping this issue would be solved, and if it was not solved I gambled I would not get a lemon. Strike two - strike three was when the tow truck driver was loading the car for the tow he pranged the front end. I still don't have 300 miles on this vehicle.
