It actually sounds like a 'normal' production line fault has simply slipped through somewhere. I say this because the fault is appearing almost instantly upon first use, has the characteristics of a hardware fault (which could be anything down to a single dud box of switches) and would normally be uncovered in the post assembly inspection and testing. The fact that the fault occurs once the camera is switched off might explain how it slipped through. I'd imagine final acceptance testing focusses on faults during operation; test, observe, record, switch off and move on to the next one. Much more susceptible to human error on the part of the QA inspector as opposed to something going wrong during the test firing.
As I've alluded to earlier, I see it as more positive than negative. If the issue was a design flaw, I'd be disappointed and would probably have held off ordering one. I haven't upgraded my body in seven years, so deciding to order one wasn't taken lightly. Hopefully get mine today, and if it's a dud it'll be pack in the box for an exchange.
