I have a front wheel drive escape plugin. I do not get power to all 4 wheels. The Ford service guy told me to run the warmup cycle during charging to get power to the 12-volt battery during the charging. This shuts the battery saver notification down and turns the interior light on when I open the door, but it is effective for only one day. The alternative, he said, was to buy a charger. Other forums offer a larger battery as a fix. Comments about that idea bring concern about voiding the warranty.
