While all this has been going on, Tesla has been working their plan.
They are making much higher quality cars now. Warrany expenses have dropped and the cars need much less service than before. No longer do you need to change your differential gear every so many months etc.
They have cut out chit chat at dealerships. Owners get notified when their car is ready for pickup. They are not advised a couple times every day as to the latest (and usually inaccurate) estimates.
Paint has gotten much better, so fewer need to come in for corrective actions, Falcon wing doors are much more reliable, lighting has been improved, drive motors don't need replacement as often, and even the flush mounted door handles have been redesigned to be more robust.
Behind the scenes, Tesla is making constant improvements to reduce the number of cars needing service visits. Ranger services have gotten more capable, robust and effective.
Computerized analysis of service data gives them a day by day review of service requests.
I know it is easy to complain, especially when your greviances are valid, but I somehow believe that Tesla is getting a handle on their service system.
