I'd be interested in how many times each car had to be seen by the manufacturer, rather than full breakdowns (i.e. at the side of the road, can't continue the journey). EVs should be much more reliable in terms of full breakdowns, but with all of the complex systems I've seen more small things go wrong.

Tesla reliability is also often conflated with "build quality", and the sources for Tesla's poor build quality differ vastly, but a not-insignificant source of it wasn't objective information but rather surveys. Surveys that specifically ask "How does build quality compare to expectations". Which isn't a fair question because people hold different expectations for Teslas than other cars.
