Tesla dealer/service center is about 2 miles from me and there are 3 or 4 independent shops in town that work on Teslas.
Early model Teslas had battery problems, but everything manufactured after 2018 seems to be very reliable, to date only 2.5% of batteries have been replaced, with much of that in pre-2018 models.
Consensus seems to be that the battery should last 10-20 years and 300,000 miles, much like the longevity you’d see in the best of Toyota or Nissan vehicles.
In any event, I’m prepared to write-off my $21,000 investment and buy one of the high quality Chinese models once they become available.
