The problem I am having is that when I first got my car, I was getting 140 mile rated range. With the software updates, it has steadily dropped. For a while, it was at 135 miles. It is now at 120-122. I see a drop off as it sits in the parking lot at work. It can go from 122 to 117 by the end of the day. That is 4 hours. Overnight, it can be more like 8-10 miles. I tried turning off the Always Connected but I didn't see a difference. It is in power saver mode. Not sure it made a difference. I read from earlier post about asking the Service Center about taking the software limitation off and charging the battery fully and then resetting the software limitation. They couldn't find anything about this.
