So, couple months have passed, and I want to share my experience.
I'm based in small EU Baltics country called Lithuania, no service center here. Closest ones are in Finland, Poland and Germany. 8-12 hours drive (with a failed bearing!). First, I tried opening a ticked on the app. They use some kind of script to sort these tickets and mine got missorted. After few days they said they moved my ticket to correct department that will "contact me later". They never did.
Then I tried contacting Poland/Warsaw. All phone menus are in polish, pressed something, waited 30 minutes, no answer. Mind you, these are international calls.
Then I called Finland. Menus also in finnish, pressed someting, got an answer in 45 minutes. Definitely not by native Finn, Indian accent. He said bring the car in. I said it's too cumbersome and expensive, would like to just buy the parts. He warned that there will be no warranty for whole drivetrain if the bearing is replaced "incorrectly". Not sure if this applies to use of non-tesla branded bearings. And then he said to open a ticket in the app, which I already did and it got nowhere. So useless.
Then I found they have two public emails, sales@ and service@. Sent an inquiry to both. Silence for a week. Then someone replied those are wrong ones and for parts I should contact parts@, which is not publicly visible. OK I did that. One more week later I got an email with question if I really want to do this, better bring the car in. I explained bringing the car would cost me over €1000 and 3 days of my life, so I prefer to just buy the bearing please. Few more days and I get a quotation for ~€350 incl. shipping to Lithuania.
Note that all of this communication and me desperately trying to get the genuine part took over a month. Of course no local repair shops wanted to deal with it. Due to this same reason, insuring a tesla is 4-5x more expensive here, compared to other brands. For example, I paid €600 for €65k worth IONIQ5, and they asked €2k for model 3, worth €40k.
So I got fed up and just bought the thing on ebay for €75 incl. delivery and replaced it in my yard, took only 15 minutes. It's really that simple, only few bolts.
So there goes tesla's warranty.
By the way I am getting terrible FM audio quality since 2023 January (clicks and pops). Complained about it to the Finnish support guy over phone and he suggested to restart and shutdown it, and if it does not help, to bring the car to service center.
Someone else here on forums said they were promised by tesla this will be fixed with 2023.20 update. Got it a few days ago and no, problem is not fixed.
Quite disappointed with the whole experience, just happy I don't have many issues, it would be a nightmare.
Main problems in my opinion:
1. tesla's support is really difficult to reach, and then they are not very helpful
2. if there are no service centers and no roadside assistance, tesla should at least offer the parts for free. Like I buy the part and mail bad one back, then I get full refund, including shipping.
3. no way to report bugs. I know Elon does not want to listen to dumb customers, but this really prolongs fixes. Like this audio problem, I'm suffering for half a year already.
4. I had various other questions/issues and tried to ask on FB/reddit tesla groups but got banned/deleted immediately. What's up with that?
Overall, my European 2021 model 3LR (chinese assembly) is holding up way better than early production 2021 IONIQ5 (P45), which was serviced like 20 times already, with various non-EV issues, like broken AC, seat mechanism etc. So my next/second car would probably still be a tesla.
