Temp drop makes electronics go crazy

[polskifacet]

First time temp went under 30f, 18f today and I get high idle around 900 rpm. The easy exit/entry turned itself on and it is not configurable, its greyed out on the screen. Happens every year, resolves itself at some point. WTF lol.

The high idle @ cold temps is quite normal IMO! the initial open loop is likely to be 1000-1100rpm... does take to much cold weather to do that.  After the block is warm mine slows down to 600-650.  Very cold weather will cause it to persist!  Z

Check your Battery/terminals etc especially with the BOOMIN SYSTEM! 
Does the Battery Saver come on the Screen?  Z

Never seen the battery saver. First time it happened a few years ago, I was stuck in traffic and it got the trans to 190. Always resolves itself, just interesting.

I have been having the battery saver come on. Before I could sit in the car a minute with the engine off and finish up a song while texting in the car. Now the battery system saver comes on.

Anybody try installing a battery wrap?  DEI makes some ...  I might try it this year, been sitting around a few years LOL.

I had that start when it was still warmer outside.  I posted here and was told it means battery is on last legs.  I replaced the battery and no problem since.  Could be you are in very early stages of battery going south?  normally fine, but the cold is just enough to push it over the edge..

Its a 2015 SHO with 32k miles. I would hope the battery is not bad. Does Ford Warranty that? Getting more and more Key not found and memory Seating position is not working or glitchy as well.

Its a Juke of 2015 with 32k miles. I would hope the battery is not bad. Does Ford Warranty that? Getting more and more Key not found and memory Seating position is not working or glitchy as well.

I had the battery in my 2011 replaced under the original factory warranty
