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).

On my part, I have not heard of any > widespread Tesla failure. What reliability problems is C.S. referring to? Anecdotal, but I know of quite of few Ss that have had their batteries replaced/repaired in warranty. On my ~130k mile 2013 S, the battery was recently changed. There was no real obvious issue but the Tesla service people said it should be changed. Range was still above 90% of original and I had not complained of range loss; I considered the loss reasonable. I would guess 30-50% of Tesla with more than 100k miles have had their batteries replaced. Probably all under warranty; I have heard of no one who had to buy a battery. Fact is, cost of replacement in generally unknown. It seems Tesla is not replacing with new batteries. In some cases they install a loaner battery while the faulty battery is being refurbished. In other cases they replace with a refurbished battery. I assume the refurbishment involves replacing a smallish number of bad cells. Much in contrast to Nissan, the battery replacements are painless; as mentioned, I did not even know I had a battery problem but Tesla was eager to make it right. Nissan refuses to replace obviously bad batteries. -------------- next part -------------- An HTML attachment was scrubbed...
