I just purchased a 2014 i3 and am enjoying it. However, when my wife drove it this morning the range dropped 10mi suddenly as she was driving down the street, then the drivetrain error flashed and it said to drive it in for service. She parked it in our driveway and it sat not charging for about 5 hours. I went out to start it and it drove with no issues and no error. I have 3 more days to return it, no questions asked. It has 60k miles on it. Range is only about 40 mi. Currently charging level 1until we get a level 2 charger installed. Thank you!
