So I went looking for new to me tesla yesterday and found a post refresh 2016 P100d at a non tesla dealer here in Colorado. went I wanted to drive it but the charge was very low. The dealer is just across the highway from the Loveland supercharger, so we took it there and charged it. after the charging session the charging screen showed a balance due and needed to add a new form of payment on file. that struck me as odd. do car loose there free supercharging after being sold now? my first tesla is a 2012 S85 that I bought a few years ago and it has free SC even though I am the second owner.
