I’m just speaking from my experience as an SQE in automotive 10 years ago. There’s no prejudice everyone tries to cut corners, everyone wants a cheaper supplier, faster.

Even if the materials are chosen correctly, they’re still made in China And in my experience China is hardly ever able to produce material certs that match spec, and US engineers look the other way. By the time you’re asking for certs, millions or billions have been spent, and often product has already been shipped. There’s really no bureaucratic way to unwind the mess that was made way above your pay grade.
