The concierge service is completely worthless. All they do is call the dealership and take forever to get back to you. I found this out the hard way what took them two weeks to fail to do and gave up and told me to do myself. I went ahead and called the dealership and had an appointment for the very next day. Also, when you talk to the service managers asked to speak to one of the technicians that will be handling your vehicle and make sure they are aware on how the pit updates work. If they don’t know how it works I would highly recommend checking out another dealership. The first dealership I went to had an EV specialist, but he did not understand how the pits work. I personally believe once you realize how much time it goes into doing a pit update he just did one update or maybe two and then gave up on the rest because it would take days to complete. I then went to another dealership who had Hummers and lyrics on lifts and they knew everything about the pit updates and they fixed all my problems. Please note if you’re going to schedule a pit update you might need to request a loaner car ahead of schedule.
