Can You Trust Tesla's Impact Report Regarding Battery Packs? The Answer Is No

[NV Ray]

I believe according to wk057, it seems many of those failures are due moisture via vents and the AC drain being on top of the packs. Later builds mid 2015 and newer with design changes, seem to be doing much better even in their point in history.

I suspect failure rate will be less in the future with newer designs.

Vendor - Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)

There are some definite trends with early battery packs failing in earlier Model S vehicles... from day 1 builds up to about Q4'2014 and some even Q1'2015... and any cars that have had Tesla-refurbished packs installed. The issues are all pretty much the same thing in one form or another...

Good information, thanks. I respect @wk057 advice.

Tesla will not disclose service records to someone who wants to buy that exact used car. If the owner doesn’t know the service history, Tesla will not say a word. So what makes anyone think Tesla would be forthcoming about hv batteries that have been replaced under warranty and out of warranty? We will never know that true number, because Tesla does not want the public to know
