True! Nothing can boost sales as efficiently as a 100% customers' confidence in the product (and the producer). When you just KNOW you can grab ANY product made by such-and-such company from the shelf and go home with the conviction that you will use it tomorrow morning right out of the box, with no issues at all, only than you can call it a trusty brand...:concern:
But, I must say (and it does not comfort me) that Nikon is no exception in this regard(s) - I had similar problem(s) with my Olympus PEN, as soon as I purchased it, a couple of years ago. First, I realized there was a problem with the internal clock - it got reset every time I replaced the battery/left the camera without the battery (even only for a few seconds). To my great (and bitter) surprise, after thoroughly searching the Internet it turned out that: 1) not only this was a common issue for many PEN models (mine was/is E-PL3) but 2) the producer (Olympus) had not publicly admitted the existence of this ("generic") problem. Now, here comes the best part of the story: just when I got kinda used to this (I did not want to send it to the nearest authorized repair shop, since it is in another country:fatigue

I had discovered that the distribution of the light across the frame is uneven every time I set the camera's noise reduction to "off" (switching it from "auto" or "on"). It resulted in photos' right-hand side being overexposed for about 2 stops (1 stop brighter than the center and 2 stops brighter than the left-hand side) if I was shooting with the noise reduction set to "off"! Was I MAD, was I furious?! Finally, I send it in, and the repair shop needed to replace the camera's "motherboard" or "mainboard", which practically meant the complete electronic part of the hardware (allegedly, in addition to the malfunctioning of the capacitor that keeps the timer "alive" until the Li-Polymer battery is replaced with the freshly charged one, there was some problem with the image processor whose "instructions" regulate the noise suppression, among the other things).
