Teslas seem to have a reputation of being locked down and requiring first party repairs. As an example, Tesla charges extremely high fees for its repair documentation to shops.

Considering how many Teslas have been shipped, a postmarket community forming around the vehicles seems likely. I just don't know how successful it will be when the manufacturer is so hostile toward third party repairs and tinkering overall.

I don't doubt they are reliable cars, though. So are Apple computers and phones.
