It depends on the difficulty of the "fix". half an hour per car doesn't seem that bad, and while they will clearly try to fix that (and I'm not trying to imply they shouldn't), I don't think the fact that they are continuing to pump out cars with a "flawed" system (while presumably working on solving the problem internally) is any indication that they are unable to scale forever.
