I don't really think so. Pundits have been saying it every year .... every year is the year, every quarter is the quarter .... You need to understand one thing, Tesla's customers are NOT interested parts so they can fix it. You are describing yourself or a guy who loves to fix cars in his garage. That's not what their customers want. It's a zero problem for them ... the guy Brian P referred to, buys basically written off cars, after fire or flood. He's like the 0.01% of Tesla's customers.
Typical customer wants Tesla to fix their car and for the most part, they achieved that ... sure you will find the occasional YT rant, but they are really rather very small number of their customer base who walked away unhappy.
Will they be going through teething problems? .... sure they will, they are 10 year old company, trying to do a really big thing. Just saying ....
That likely applies to Tesla's
current customers - who are, for the most part, (1) rich or at least relatively well-off, (2) have other vehicles to use when the Tesla is broken, (3) "early adopters" willing to overlook the sacrifices. And the cars are mostly still under warranty ...
It probably mostly applies, for now, to people actually going through with buying a 3 ... which is not an inexpensive car.
The problem starts being revealed when you deal with the everyday person who will want to have the car fixed by his local mechanic who charges much less than the Tesla service shop ... but won't be able to.
The cars will get reputations for being expensive to keep on the road ... and then resale value will crater when they are out of warranty. Same reason a BMW 7-series or Mercedes S-class that is a few years old is less expensive than a 3-series or C-class, and not many years beyond that, cheaper than a Honda! No one wants to touch one of those cars when they are out of warranty. Driving an out-of-warranty Honda? No issue.
I don't necessarily want to fix my own cars, either, but if I were to buy an EV, the local GM dealer is a lot less expensive to deal with than a Tesla repair center.
Part of the reason for buying a FiatChrysler van instead of a Mercedes is that if, sometime, years from now, it needs an alternator or some such thing and I happen to be out in the boonies, it's a whole lot easier to find a mechanic who can fix a Chrysler instead of finding one who can fix a Mercedes.
I drive vehicles into the ground. I will not buy a Tesla until I can buy parts for them anywhere. If that means I will never be buying a Tesla ... I am perfectly fine with that. I am quite sure that I am not the only one with that opinion!
