Update - The service center in Scottsdale called me about an hour after I spoke with customer service and shared pictures of the errors. He said that he would have a mobile tech here at 10 AM. Sure enough, a fantastic service technician showed up and started working on the car; because of where my garage is, he did not get a strong enough Wi-Fi connection to send data to the engineering team. So he pulled the car outside next to his van, which is equipped with high-speed wifi. They diagnosed the problem; it seems like the update failed partially through the process, perhaps because of the location of my garage (I live in a condo, and my garage is underground, and we don't have wifi down there); often, no cell service.
I did not know the redundancy built into the car; there is, for lack of a better way of describing it, a left brain and a right brain. It seems the left loaded correctly, and the right did not. So one element I did not mention in my original post is that the lights on the left of the car worked and the right did not. So if you looked from the back, lights went from the left side to the C in Lucid. The tech explained that computers on each side control the lights. standing by
He told me when he arrived that he had an engineering team standing by to diagnose the issue. They figured out what parts of the update failed, but they had to reload the modules that failed individually. Because his high-speed wifi connection is good but not super fast, it would take a long time for all the packets they were sending to arrive and then update. He asked to take my car to the service center, do the work and bring it back later today after all the packets were installed and the 2.4.47 version was installed. One interesting observation is that the current version was installed according to their initial diagnosis, but the car indicated that it only had 2.4.45.
At 4 PM I received a text from the tech. All problems had been resolved, the update was complete, and he was headed back with the car. He pulled it into my garage at 4:15 with everything working.
This is probably the best service experience I have ever had from any luxury car company. They had one person and an engineering team work from 10 AM to 4 PM. It sounded like this was not something that they had seen before, and I hope to learn a bit more when I get the service update about what they did.
All-in-all - FANTASTIC SERVICE! A big shout-out to John in the Scottsdale service center, that got this rolling so quickly. An even bigger shout-out to Keona the tech and the engineering team that worked to solve the problem.
If they can continue to deliver service at this level, they will be extremely successful IMHO.
Thank you to everyone for your input.
