Clearly, a lack of TMS has turned out to be a gigantic engineering mistake.
Not sure I agree with you. While I live in West Los Angeles, my Leaf is parked in the sun in Canoga Park for 40 hours a week. I haven't lost any capacity bars, and my 100% charge today was 254 Gids (90.4% of capacity retained) after 22 months and 17,000 miles. There isn't a huge difference in the predicted rate of capacity loss between Van Nuys and Santa Monica based on the Battery Aging Model. What is puzzling to me is why some people such as yourself have lost 2 capacity bars, while others in fairly similar environments haven't lost any. Your car may be an outlier in terms of the rate of capacity loss for your area. It would be good to know the rate of capacity loss in the greater Los Angeles area. Perhaps there are other factors not accounted for (QC, leaving Leaf at 100% for longer period of time, manufacturing problem, phase of the moon, etc.).
what about driving styles? Tom makes it no secret that he just "drives it, like he stole it". Do you? aggressive driving might be generating just enough heat to kick the degradation up that one iota?
you are a pretty mellow driver (based on my warped memories anyway... I maybe wrong) and maybe the degradation is the difference between driving 60 mph and 70?
