In our local neighborhood, there have recently been a huge number of car break-ins, that appear to be using something like this technique. Interestingly they mostly don't steal stuff from the car unless it's really easy (like cash); they seem to be much more interested in identity documents...

I don't see anything that lets me definitively conclude that Tesla is susceptible. Since it is a generic RF-relay attack that simulates the key being closer than it really is, I suppose it's possible for Tesla to be susceptible to this, but it's also possible that the security that exists between the two would not allow for their device to "impersonate the key" in the first place to generate the message required to relay back.

Note the Model S and Model X use different key mechanisms as well.

(Note: this forum does not have official Tesla representation. If you are an owner, you can contact Tesla through its service number to ask the question.)
