Im still waiting for my FSD and MCU2 upgrade. Had service appointment 7/23. Showed up at SC, sorry parts are not in yet. Didn't inform me before driving over there (30 miles away). Ok, set a new appointment for 8/11. .....
That morning I tried to contact ANYONE to find out if parts were in or not, finally got a reply from SC tech who texted me last time. No, parts not in yet.
ARGGGG
So, now I have an appointment for 9/9. Last parts email I got says Shpping

ending, still.
Is this a difficult thing for anyone else?
