  Knowing someone in a Tesla authorized service partner I can confirm the practices are... not great. According to the agreement they signed to become an authorized partner and under the threat of withdrawing said authorization, they have quite a few limitations that make for longer wait times and more expensive repairs. For example they are not allowed to order extra parts for stock (they have to "tie" them to a car in service) and they are not allowed to use aftermarket replacement parts even if compatible. I am specifically referring to car parts, not consumables. So break pads yes, break calipers no. Light bulb yes, headlight no. For example you will not find aftermarket headlights for Tesla that you can install in an authorized shop, get warranty, and ideally not discover that the car already logged the use of an AM part. In this case most (all?) aftermarket headlights begin their life as an OEM part that gets modified and this pretty much bypasses the restrictions, technical or administrative. These restrictions may be lifted as Tesla becomes better at making cars and can dedicate resources to making more spare parts, and as they start to allow others to take a bite out of their profit by manufacturing compatible parts but we are not there yet.
