I think, in this particular situation, it's more that Subaru themselves don't really know how to approach fixing these safety systems. From my experience these systems are fickle-beta-hot-garbage-heaps brand new. I bet they see right to repair bills as a way for the general public to gather evidence that they've known this all along.

Of course, this doesn't really address the issue of people buying cars from out of state. But who knows, maybe we'll see "Massachusetts Cars" be a thing in the Subaru world for their lack of broken factory features.
