All you can really do then is hunker down and work together to fix the problem. There's nothing to be gained by alienating the only people who can fix something which is, at the end of the day, making you look bad.
In my opinion, however, the most important trait of a press statement regarding defects/problems is who outright says "I (we) accept full responsibility" or "I (we) place full responsibility on X". If that isn't ever said in some way, shape, or form, and it's just implied, I think that shows less character than at least making a call one way or the other, and accepting the consequences.
