I am in the midst of a service horror story, and I’ve seen enough in other places to know that this is not an isolated incidence. As best I can tell, the vast majority of these cases occur because Tesla has substantially cut back on personnel and resources to their service centers. This is a deliberate corporate choice and it is rapidly killing the brand. Hence the subject line. In my case, I made an appointment several weeks out to install FSD, which I paid for 2.5 years ago, in my 2017 MS 75D. The appointment also included an upgrade of MCU1 to MCU2, at my expense. I received emails on the status of the parts ordered, one of which had not arrived as of 5 days before the appointment. I tried desperately to reach the service center (Dedham, MA), which is more than an hour away from me, by phone, phone messages, and texts, to no avail. That, in itself, is unacceptable. Finally late in the day before the appointment, the SC texted me and said that they would put me me in a loaner until the work was complete, so I made the drive to the appointment and returned home with the loaner. BUT, the next day, they called to say that the wrong MCU part had arrived, that the right part would take 3 weeks to arrive, and that they needed the loaner back. They refused to send somebody here with my car to get the loaner. They want me to essentially make two two-hour drives due to someone’s mistake at Tesla. This is not acceptable under any circumstances. A mistake in a parts order can happen, but not having enough people to deal with it is a corporate problem. It seems to me that Tesla is being penny-wise and pound-foolish with its service. Word is getting around about how poor the service is, and, being active on social media, I intend to help spread it, unless something drastic happens immediately. I certainly would not recommend buying a Tesla right now.
