Unfortunately, manufacturers' interests are often not aligned with retail customers' interests. For example, with Tesla, the company optimizes delivery numbers of cars sold by sacrificing quality control, and their service center model is anemic and almost an afterthought, especially when it comes to addressing the QC issues their customers experience. For every Tesla with 400k miles on them with a few thousand dollars in maintenance costs, there are a dozen cars that are delivered to customers like this one[1] from today on r/TeslaLounge, with 17 blatant issues upon delivery that QC should have caught early on in the process. There are stories on that subreddit about customers having to wait months, without a loaner car, for service centers to fix their cars or to even get service centers on the phone about the status of their repairs and cars. Dealerships act as an intermediary customer that can perform QC, repairs, customization, service, maintenance, reject deliveries etc that manufacturers choose to skimp out on.

You need an actually random sampling of delivered Teslas to determine how extensive QC issues are and whether the average one can go 400k km with only $3k servicing. Also, they defects reputed to vary substantially over time (e.g. one model year might have 5x the rate of two years later).
