I don't doubt that is true, but the responsibility lies with the company management and executives that allow this kind of crap to get out to customers. It's not hard to setup a robust Quality Control system in a manufacturing plant and they have tons of experience with it in the automotive part industry. Of course you need some level of buy in from the employees, but again that is up to management. Kinda falls under the "management" title. What else are they doing? It doesn't matter if the plant is in Michigan, Mexico, or Asia. If this was truly a new out of box part and not some sort of return or fake, someone at Melling should lose their job.
