I've got a 2013 Model S 60 with ~42k on it. Drive normally in LA (traffic, no freezing weather). Original range was 208, now can't get past 165, about 20% down. Repeated visits to Tesla service end up with the same answer: the battery is fine and nothings wrong; essentially, "sit down and shut up." Finally, I wrote a letter to the CTO explaining that if GM's cars had a 20% reduction in their gas tanks in ~40k miles, there would be a recall. That letter did nothing - just another local guy called me to tell me nothing's wrong. Worse yet, I'm still such a believer that there are at least three people who have bought Teslas thanks to my referrals. Is anyone else having this problem from normal driving? Am I crazy to think I'm being mistreated?
