Alignment issues can be due to part manufacturing issues, but they can also be due to assembly issues. Everything I've seen suggests the problems with panel alignment on the 3 are in assembly, not panel/parts production. Until we start building cars where the panels align perfectly regardless of how they're assembled, there can be issues with panel gap/etc during assembly.
