As for the issue at hand, yes, it's mentioned nearly at the beginning of the book, when the narrator is discussing the motorcycles each character has and why they chose it, mentioning the two views. If I recall correctly, there's no discussion, it's simply there to give an example of the concept of quality that the author is trying to define. Anyone thinking that the book has anything to do with actual motorcycle maintenance (or worse, trying to use the advice) didn't understood the ideas and concepts of the book.
 The tinkerer, open view, exemplified with an old motorcycle (of which I don't remember the make) vs the "it just works", closed view, using a brand new BMW.
The difference is cars need regular maintenance and computers don't. The author is claiming maintenance on Tesla's is difficult, but he dismissed the point that they might not need regular maintenance like other cars.
I think only time will tell (a justification on most of his points) whether Tesla is the Mac of cars, or if Teslas still need regular maintenance.
Consumer Reports claims that Tesla does not have high reliability. Defective drivetrains are far more common than they should be.
