Service centre seems to have no clue what is going on. Got my email last Friday about the seat belt issue, with a link to book a service centre appointment. Booked for this morning, got email confirmation.
Showed up this morning, they had no idea people were bringing their cars in starting today. SC staff said "oh you shouldn't bring it in so soon, we don't have instructions from US HQ on the repair yet". I was kinda speechless so I just showed him the email from Tesla saying it needed to be checked by SC and my appointment. So he was kind enough to take my key from me and said "hopefully it'll be done by the end of the day, leave your no. we'll call you."
So much for a 15m turnaround.
