As a Tesla owner I was surprised they're that low. I know probably 30 owners and haven't heard of any maintenance outside of tires and a few panel gaps at delivery.
A lot of it is likely software update that they call "recalls" etc. But just guessing. I have two and they are very reliable.
Would you expect them on higher or lower rank?
Given the media reports about the cars quality, I would expect them to be much lower. Then again, I don't know anything about cars.
Media reports are sadly about as reliable as that story from uncle Bob.
To pick a random example, I just saw one saying tesla touch screens overheat, leading glue to leak inwards into the screen and making them unresponsive. Are you saying this isn't true then?
Even Uncle Bob is correct some of the time. My point being that media over sensationalizes issues and that basing your view on reality through their port window is risky.
