Questions to ask....
Did anyone unfamiliar drive your car? Such as: parking lot attendant, valet parking, car wash personnel, at the dealer, did anyone need to move your car for any reason, did a family member take the car (authorized or unauthorized) without your knowledge?
Was it parked anywhere where it could have been vandalized (or someone trying jack it up, or move it, push it with another vehicle, attempt to load it on a flatbed tow or other tow device to steel wheels/tires?)
Could someone have gained access to it to your key/remote/etc without your knowledge?
Is it possible you drove through a construction site where metal plates covering a hole in the pavement could have moved, or a manhole cover popped up to do this?
Did you cross a railroad grade crossing where you may not have been aligned with the pavement, perhaps at night?
Suggest you request any Tesla data logs that may show any longitudinal impacts sufficient to do this damage, and/or a disturbance to the battery voltage might have been logged? You or
your insurance provider might consider to contract with an independent investigator who has the Tesla airbag download tools. Even if the airbags did not deploy, a "trigger" for an event could be stored, which might shed light on when such an event occurred, and if there is any other data to link it to other actions (braking, acceleration, steering, battery power, etc.). I provide those services here in California (and sometimes elsewhere as well).
