Yes thanks, I changed the FOB I use the most about 2 months ago, and I changed the batteries in both FOBs last night.  That was a weird experience, the dealer shop replaced the battery and glued the loose carpet strips in the back with some double sided tape but when I went to leave touching the front door handles locked the car and touching the back handles unlocked it.  The FOB buttons work as expected.  The Advisor offered to have the car reprogrammed but I was there late and all of her techs went home already.  I'm guess I'm taking it back in to get flashed tomorrow at no charge.  I drove it to a restaurant for dinner and when I came back out the car seemed to work as expected, then when I got home I tested things and it was like the driver's door was alternately hypersensitive to putting your hand anywhere near the lock pad on the front door handles, if I grabbed it ONLY on the front part of the handle it would unlock - sometimes  it wouldn't respond at all for a few seconds.  The BCM seemed to be acting slowly..

 

So I'm not exactly sure what is failing - the antenna?  the BCM?  Bad settings?   I don't know for sure.  I guess I'm glad I have the new battery anyway, it might have lasted one more year if I was lucky probably.  The dealer didn't want to change it because it tested good.  They thought I would be mad if it didn't solve the problem.

 

They apparently have a "hybrid specialist" that only works certain days for $105/hr  .. I guess sort of like how some shops bring in a specialist for transmissions?  They wanted to have that person do a diagnostic.  I guess if the re-flash doesn't work maybe I will.  This is a presidential award winning dealer that does work for miles around.  and I'm glad they are trying to help me but It's funny that the shop where I bought the car at a little country dealer seemed to know more about hybrids.

 

Oh, the new battery with tax, labor etc. was about a $200 charge.  I remember how much fun I had changing the battery in the Prius and the C-MAX looked to be about just as much fun so I guess it was worth it.  By the time I would have bought all the deep sockets or whatever, and it's cold out this time of year I guess I would have spent about the same amount.  Amazon wanted $140 for the battery + $26 for shipping.  Some of the online Ford dealers were selling it for about $90.

I originally took my 2013 Energi to a local (non-Ford) shop to get the battery replaced.  They worked on it for an hour or so, got scared by the bright orange cables, and gave up.  At least they didn't charge me anything!

The car ended up being fine, within 24-48 hours after the change it now operates normally and the dealer tested it, found proper operation and didn't reprogram anything.  I guess maybe when I went to grab the front door handles maybe I inadvertently touched the lock pad or for the first day or so between the new 12V battery and brand new FOB batteries everything was hypersensitive.
