The headline of the first article is "Toyota is recalling 1 million hybrids at risk of catching fire", did Tesla ever do any similar recall, because of potential fire risks?

You don't get a car recalled if customers don't report issues.

Customers don't report issues if you force them to sign NDAs to get their cars fixed under warranty.

That wasn't a battery issue though, it was a wiring harness issue. That's a relatively common problem even in gas cars. Cars have a lot of wiring.

Nothing to do with batteries or chemistry, it is some insulation on the wiring harness that can wear away.
