We parked our 85-D in our garage on 27 July and plugged in for a charge to 201 miles. We unplugged after charge complete and have left unplugged through today. We have not driven the car since 27 July. We are now at 146 miles. This is a loss of 55 miles in 12 -13 days. We live in Scottsdale so our garage is 90+ degrees 24 hrs a day at this time of the year. Any comments on this loss?!?! And is there a good reason to always leave the car plugged in?
