Went thru the same process for the Grapevine SuC just sitting there looking ready to go. Seems the (small) city of grapevine just north of the DFW Airport, has to exact there pound of flesh with city inspections, checks from Tesla to clear their bank, handshake with the TSLA rep on site with the electrical contractor there and perhaps unimaginable bureaucratic processes. There are no doubt countless inspections and such that the City of H is behind on - it's a make work bureaucratic world. However Grapevine seemed to run slow on charging for 30 days (approx) once it was open - break in period - I don't know. But just Sunday got a much faster charge and was surprised to hear my charging cooling system spooling up seemingly louder that at V2. And for that period of time, at least for my 2019 MS, I could "Navigate To" the SuC and not get preconditioning message prior to arrival. Hmmmm, I'll have to check it today.
