I have a question to all of you that charge your car to it's daily charge level at 90%, I've experienced loss of charge over the last couple of months and would like to get a feedback from you on what's the Rated mileage you get when charging is complete? I had my car serviced the other day and the Tesla loaner they provided me charged to 241 miles with Vin #37xxx and about 5500 miles on it. My car is #13xxx and has close to 14000 miles on it. The loaner rated mileage immediately drew my attention, as my car would charge to levels between 223 and 230 but never over that. I've done a "tuning" full charge as suggested by Tesla SC a month ago, but no significant difference. Here is what Tesla said when I brought the complaint again when my car was in the shop (direct quote from the service invoice): "Concern: Customer states daily rated ranger is between 223-229, loaner car is 241. Please advise. Corrections: Battery Assembly General Diagnosis Overall battery health appears good, there is some diminished capacity over time and environmental conditions will have an effect on overall capacity." I live in the Boston area, so I'd like to know what these environmental conditions are and I find it strange to have lost 11+ miles of Rated charge for just 14000 miles on the car. If we assume 300wh/m is the rated formula (for easier math), it's a loss of 3-4kW in the pack, which is significant for 1 year old vehicle. What are your experiences and do you think that's normal wear and tear on the battery? I love the car and I'm not concerned so much at the moment, but in 6 months or year, if this continues then I'll have a serious issue on my hands.
