I was looking for more info on this too - I hate that I have to turn Regen on every time I start the car! All that materials say:
"Once selected, the Max Regen feature remains engaged until driver deselects it." Not True!
Sounds like they are changing this based upon the interview done by wrangker4xefans with one of the Jeep engineers. If I understood correctly, it should be in a few weeks but has to be done at the dealer.
