I'm just wondering if they are using components which were constructed and then not used right away. I work for a company that manufactures complex products, and in our old process, some of the components and sub-assemblies could sit around for weeks or months before they were actually used in a build. We knew the build date for the end product, but the components used may have been assembled long before that build date.
I have no idea what kind of processes FCA uses, but I can imagine a scenario where a cab is assembled, and then sits for a while before it's used in a build. Maybe that cab was assembled before the star report was issued, and the fix was not applied? Maybe stretching there, but who knows. We're on the outside looking in, and they're not very forthcoming with any information to the end user. Just throwing that out there.
