After seeing the state of the delivery center area at the factory in Fremont when I went to pick up my car at the end of July, I got the impression that Tesla is really struggling to keep up with incredible demand for it's cars. The sheer number of cars being staged for pick up and transport was amazing, and there were a lot of workers in that area in a frenzied state. The delivery process was disorganized and chaotic, with them changing the time/location 5 times within 36 hours of delivery.
I believe the factories are pushing final QC to the service centers, and the service centers (at least the one I use in the bay) are are overwhelmed. Hopefully as the Austin plant ramps, that will take some pressure off Fremont and overall quality across the factories will improve, but I think Tesla's been building a backlog of quality issues over the last 2+ years that they'll be dealing with for years.
My car went in for service on the 16th. I noticed that the Service Center started working on my car last night from about 4pm until 9pm when I checked the app, and the invoice was posted and service shown as complete at 10pm. so they are working weekends and nights from what I can tell to keep up with service.
I had the same rattle mentioned above on the back panel of the touchscreen which they fixed. They attempted (but failed) to fix the latch on my frunk (3rd attempt via mobile service coming up in a week.) I think they've fixed the "dynamic drive control disabled" error although that message came back today for about 10 min and then went away, hopefully it will stay that way. I was charging today, at 32 amps on my 40 amp line on my Telsa connector, just like I used to with my 2017 S75, but it blew my circuit breaker, so I reset the car to 28amps which worked, but now I have to figure out if there is an issue with current draw on the tesla (ie. even though it's set for 32 it is drawing more?) or it could be my circuit breaker or connector. The service center said they'd fixed the carpet and trim that weren't attached to the side of the front passenger footwell, but it wasn't fixed when I picked up the car today, but I think I can solve that myself.
