In these videos it seems more that Tesla is VERY hostile against people who repair their car. They have no access whatsoever to parts, so their only chance is to buy damaged cars and salvage the parts. My feeling was that it was very hard for the owners to keep the cars updated and to super charge these cars.
My experience with dealers repairs and independent contractors is that most of the dealers change assembly groups and good mechanics change what's damaged. You've got less problems if you change assembly groups but it is way more expensive.
