Yeah not so sure about that. States will have different laws, and NDAs are not Non-Competes -- different story altogether.

Most states can't / won't enforce Non-Competes, but NDAs often have teeth.

Most states also have warranty and lemon laws, often specifically aimed at cars, so you could fight the NDA or ignore it and push for a warranty violation or lemon law case.

File a lawsuit to get them to lemon law the thing. Court testimony is public record that can’t be NDAd.

That doesn't mean NDAs are unenforceable. It just means you're getting them to fix the problem without signing their NDA, and presumably going through more hassle in the process.
