Unfortunately, mine says the same thing and I have a "transfers with the car" version. There used to be a paragraph that described your supercharging status and mine said something along the lines of "and for whoever purchases your car" - a phrase that was omitted from the same paragraph on the status page of non-transferable cars. Now I can't find anything like that paragraph and those lines showing my "Supercharging Status" read the same as animorph's...
When I search the HTML source for my status page I find that my car has option SC01 associated with its "Free Supercharging" option. Perhaps there is a different code for cars that are transferable vs. non-transferable?
According to
this page, there are 4 codes for supercharging:
SC00 - No Supercharging
SC01 - Supercharging Enabled
SC04 - Pay Per Use Supercharging
SC05 - Free Supercharging
I'm guessing that SC01 might be "free supercharging transfers with car" and SC05 might be "free supercharging, does not transfer"? Can someone with the non-transferable FUSC check their codes?
The codes somewhat follow the evolution of the supercharging status over time:
First there were cars that came with it or not - all Model S - and the 85s had it, but the 60s did not (IIRC). Then they provided a way to buy into it and "enable" it for cars that didn't come with it. Thus the "No" vs. "Enabled" in the first 2 codes. At this time, the status would transfer with the car by default. Later I believe all cars ordered until the end of 2016 came with it enabled.
Then for cars ordered after the first couple of weeks of 2017, they switched to Pay-per-use for new S/X for a while, which introduced the 3rd code.
Shortly thereafter (May 2017 or so) they changed their minds, enabled all of those cars from the last few months and introduced the FUSC-by-referall program, both of which didn't transfer - which would explain the 4th code...?
