I got the 12v Battery Needs Service warning. After calling in, they tell me I should have 2-3 weeks before it dies. So I schedule the soonest mobile appointment the app will let me. A week later the mobile tech texts me that 12v batteries are out of stock with no ETA on resupply. I ask if I can take it to a service center and he said they are out of stock too. He empathetically mentions that he hopes they get them before my car dies. Yeah, me too. Questions: 1) How is it remotely possible that a part so ubiquitous and is 100% required for Teslas to operate is out of stock? 2) Are there any alternative escalation mechanisms any more? 3) Do I have any other options other than hoping Santa brought Tesla some 12v batteries? Thanks for any ideas.
