ahem Guess what Tesla has a ton of problems with?
Edit: there are a whole lot of people replying who seem unaware that I was referring to new car customers who have a vehicle which is broken under government-mandated warranties, but also that:
- The majority of manufacturers have long required proprietary diagnostic tools (the OBD-II functions in your car are only useful for the most basic diagnostic info, cannot adjust parameters, and cannot trigger diagnostic procedures such as cycling a valve or motor.) That is why some states and countries have right-to-repair laws. Automakers responded by shifting all that stuff to work only over telematics, and then claimed that online websites were not "tools."
- At one point car companies were doing bullshit like shipping parts with electronics in them "uncoded" (not uncommon, VAG does this) and not flashed with any firmware. Volvo did this. The firmware could only be flashed by a dealer, and it required them to plug the car into their internet-connected diagnostic tool through which servers in Sweden would encrypt the firmware for that specific VIN number and module, which could only be decrypted by the main control units in that specific car - and transmit it back to the technician's diagnostic tool.
- Teslas require software/online tools only provided to Tesla service centers and technicians
- You cannot buy parts for a Tesla without providing them with the VIN number of a car you own and which they still consider roadworthy. Tesla has a very arbitrary process for declaring vehicles to not be roadworthy, with relatively minor collisions triggering it, whereas vehicles nearly totally destroyed often are not declared unroadworthy and their VIN can be used to purchase parts
- Tesla does not distribute parts via third party distributors such as Worldpac, and prohibits its OEMs from selling parts, which is extremely unusual. You (and your independent mechanic) can only get parts directly from them - if they'll sell you the part at all.
The laws requiring dealerships and that they be independently owned were created because in the early days of the auto industry, people were getting endlessly screwed by automotive manufacturers producing cars that would break within weeks or months, did not have parts available for them at all, and the company would dissolve right after a production run so that customers had nobody to go after for damages.
The reason for requiring it be an independent business is simple; the state government wants to see that a local business has judged the manufacturer to have their shit together sufficiently enough to want to do business with them, and they won't be left holding the bag.
