Hi Willie etc,
It's hard to find actual published Tesla battery failure numbers since Tesla
sends internal field service guys "Tesla Rangers" out to your house to
replace any bad cells that the car radios help for. When I was at a EV race
about 5 years ago, I asked three Tesla owners if they had any Tesla Rangers
come out to their homes in the past year for battery issues. All three
raised their hands. While this business model of impeccable field service
may work for high priced vehicles/wealthy customers, I don't see how it can
be *sustained* for lower priced Model-3's (set to come out next year).
I'm SURE the ranger service will change 12v batteries; that's something
that has to be done as often as yearly and is a couple of hour job. But
removing and opening the battery case is a BIG job. In fact, I don't
believe service centers open battery boxes. Certainly, it is not done
in the owner's driveway. All battery repairs that I know of have been
sent to California.
Tesla DOES seem to be moving to more ranger service and I contend it is
likely more cost effective than getting cars into the service centers
and then managing all the cars/jobs. Not to mention being FAR more
convenient to the car buyers. Generally, service centers supply
loaners; that HAS to be very expensive since the loaners are mostly new
high end cars. The loaners may eventually get discounted with a few
thousand miles by $5k-$10k and sold as "inventory".
I REALLY hope/believe that we are not far from the point where the cars
will be driving themselves to service centers and then driving
themselves home after repair.
