i got the same message a few weeks ago on my truck; Tesla service replaced the rear inverter. I was able to bring it in the next day by msg/calling them.
A little over 3 months fs awd. Absolutely no regrets. Love the design. Drives even better. It is my daily driver. model 3 stays in garage. Like everyone says, the steering and handling is exceptional for a truck. No issues getting around parking lots/garages.
It is a large truck so it does...
Likewise, just saw that Tesla Shop shipped a replacement for mine. Maybe it is to address the latch mechanism that someone easily broke (in this forum or somewhere, don't recall).
