Tesla Is Recalling Cybertruck Batteries

But what happens when this guy's companies can't be investigated because he's effectively in charge of the government?

Then you have oligarchy.

If they’re secretly replacing the batteries then it’s not a recall. A recall needs to be communicated through NHTSA.

NHTSA permits automakers to make recalls and not alerting all affected vehicle owners. NHTSA was sued for it.

When there is no safety risk it's called TSB (Technical Service Bulletin) https://www.tsbsearch.com/Tesla

If there is a safety risk and NHTSA does not know about it, it's called shady business.

The stock only goes up though. Not sure why

Me either. And I have a bunch of it.

I bought it more than a decade ago. And I sold a bunch of it today because I hate having so much of my personal wealth tied to a raging dicknozzle.
