The real talking point here is that Mercedes are confident enough that the PU1 units will all be able to do an extra event over and above the expected "life" of the units.
It actually isn't. Most of the components have to do 7 race weekends, some components 10.5 race weekends, which means this PU would have been reused anyway, probably allocated to FP1 and FP2, possibly even FP3 of the next 7 race weekends. Mercedes is just shifting around with the run time it would be still doing anyway. The mileage they will doing now is replacing mileage they would be doing later on. So no, this is not above the expected life of the units.
The bigger issue is they will be somewhat down on settings (there is still wear and tear on that PU, within expectations) on an already older spec PU. There's a reason why manufacturers prefer to introduce a new spec on this circuit even if on average one race early on schedule: it is a power-dependant circuit. Having a fresh and updated spec PU here brings the most value.
I wouldn't say either Mercedes are panicking or in trouble. Although something as vague as "a quality issue" can really be interpreted in a lot of ways, ranging from a bad batch out of production to a design mistake (using too few material to strengthen a particular part). In my opinion, mercedes having production errors on a total of 6 PUs doesn't sound like Merc. I think something broke on the dyno test, sending the whole thing back to the design department to iron out the issue. It's only a delay of one race, so Mercedes probably have gotten rid of the issue by now. That doesn't look like a cause for panick, probably a cause for irritation and a bad mood on the work floor, but nothing else.
