Well...here I am again writing a post about the 12v battery. The last time I posted, the car was dead "out of the blue" and after many suggestions...I ended up at the dealer spending $170 to have the 12v battery replaced. It was time and somewhat worth it. I thought we were out the storm, but lo and behold....this morning the car is doing some weird thing again. So get ready all you helpful people, I need you again:

       The wife went to leave for work this morning and when she got into the car....the lights were flickering. Everything on the car was flickering. I quickly got my battery charger hooked up to the car and it started to recover, but not before other strange behavior. There was a message on the sync saying something about saving battery and there is a wrench that shows on the dash and a message saying to see manual. I said it last time that I have really liked this car, but I am starting to get nervous with all this electrical stuff going on. Any thoughts on what is going on would be much appreciated.

 I posted a thread a month ago on this. I had no start issues and after doing a lot of reading I replaced the battery. It wasn't but a week or so before I experienced the same thing. I did get flickering with no start. I did some more reading and read a lot of guesses as to what was going on. The best I was able to determine was that something that should be shutting down wasn't and draining the battery. 

 

 Thinking about what I did differently the only thing I came up with is the door slide locks. When I first got the car out of habit I always used the remote. I start using the door touch locks. I never did like how they worked. Sometimes I would have to touch and slide a few times to get them to work, either lock or open. My wife's works great. 

 

 I started unlocking and locking with the remote thinking the door locks weren't shutting something down perhaps. It's all guess work but I've had zero issues since doing that. I suppose I could have the Ford garage do a diagnosis on this but I wasn't ready to pay for that right now. I would think they could see whether or not everything that should shut down is shutting down when using auto locks. 

 

 I never did find a definitive answer. It's working for me right now.

I don't use the locks at all while in the garage, but you are right....it could be some other drain. It seems there is a flaw of some sort. Thanks for the input..

 I figured that *maybe* the act of locking the car was making sure whatever wasn't shutting down gets shut down. I would think a dealer could put a car on their computer and try a few things and check this. I also have to think one (or more) have as this isn't a super rare problem. I've not been able to find a report where it was done though.

 

 It's what I would ask the dealer to do if I run into the problem again.

Ahhh... I understand. It's definitely something to try...thanks.

The blinking thing is caused by the battery being low.  It makes weird things happen but the car is OK not a problem as long as the battery voltage is up.  The drain is from something remote, not sure what it is, but something is draining the battery.  You need to find the root cause of the issue.  Don't worry about the blinking lights and wrench, those will all go away once the battery issue is fixed.

Thanks....that makes me feel better...kind of...lol. It is a bit disconcerting that I never know when an issue is going to pop up. I hope the dealer can find the issue. Thanks again

 I bought one of the small battery boosters. It's small enough to fit under the seat. Is that a good solution? No, but I know that if it happens I'm not stuck.

I heard from Tom its not good, the little battery booster thing but depends on which one you got.  He can elaborate.

About 3 months ago, after 2.25 years, I had a flat battery. The dealer looked it over, replaced the battery, and did a TSB that was for the battery (probably the same one the C-Max hybrid uses, but I don't own the car any more). It worked fine after that for the few months I owned it before trading.

 

Anyway, you might ask about the battery TSB.
