On Dec 1, 2022 I had my 2013 Tesla Model S 85kw towed to Tesla Service. They said Gen 1 DC/DC converter bad and they would replace in 2 weeks for $1,400. In late December they said, they cant find a Gen 1 converter and now I have to upgrade to a newer gen DC/DC converter and it will cost $7000. Fast forward to March and I am still waiting for the car. They cant find parts for the new gen DC/DC converter. HELP? What should I do? P.S. I finally got a loaner from them on Jan 8th. We have 2 Tesla Service centers in Las Vegas.
