"These electric cars that Tesla produces have amazing reliability."
This is an outright falsehood. They produce poorly engineered vehicles Frankenstein'ed from other automakers parts, because they can't machine their own accurately. They use a Mercedes steering column.

On and on and on.
I've not completely read all the articles you've cited, only briefly did I skim through some of them. What I did gather is that none of these things are concerning the engine - and the engine is exactly what I verbatim referred to:
"There's no extreme heat, no need for oil changes or air filter replacements, tune ups. Your engine starter failing is a thing of the past."
I was thinking more about the links you posted. I could probably find a similarly long (if not longer) list of problems with other car manufacturer products. So I'm not moved by these links.
