Yes you will need it reprogamed. With out the leaf tab you can not see battery state of charge.
Also settings for cabin precooling ,preheating and value charging.
I had to get mine redone on my 2013.
Check coolant level.
Have dealer do a coolant system purge. Ask them to do it twice. This will get rid of any air trapped in system and if one of the coolant valve are not working it should show up while they are doing the procedure.
My nephew's light ring replaced twice. I think it was done under warranty.
He drives 2012 ffe.
I have had no problems with mine. 2013 lease return. Had for almost a year.
Great car. No problems.
Try turning on Def. High. It is the red Def button above the on/off button on the hvac control panel.
Mine was not working and did this and have had heat on
Any setting ever since.
Worth a try and my save a trip back to Ford.
