Well, yes and no.
On pc usually you buy stuff from different brands and they don´t have the same manufacturing standards etc. while on the console although everything is set up by the same brand (Sony) the manufacturing of the elements that will go in there is done by different brands following the standards from Sony. In this case, it appears to be some bad batch of a particular component, it's up to Sony to exchange it or not.
With cars is the same thing, the clutch pedal from my car (Peugeot 308) is noisy, particularly in the summer, they already changed it 2 times and i won't hope for the 3rd, because it is clear by the huge ammount of posts in many forums, that when Peugeot set the standards for that component, they didn't care about the noise. It is after all, a plastic piece on a clutch pedal that is used a lot.
In future models I guess Sony in this instance will make the revision as it costs them money to swap or results in unhappy customers, neither of which is a good option. I can't imagine to fix it it will drastically increase the cost of manufacture (but obviously I'm no expert).
