Tesla Cybertruck May Have A Rust Problem

There's a fix, it just cost 6k...
They keep using the words “stainless steel” which is an alloy created to be rustproof by removing the iron out of it. So how exactly is this stainless steel if it rusts?
I'm being pedantic here, but stainless steel still has iron in it. The addition of chromium forms an oxide layer on the surface that prevents rust. If the body is rusting, that means they used a shitty grade of stainless. Stainless with an appropriate amount of chromium (and nickel) is expensive as fuck.
Stainless can go goofy after working it. Work hardening can even make stainless magnetic. Sorry, I don't know the physics of why.
