Sorry to hear about the issue with your camera. I've got the same issue which didn't really get fixed by Nikon service center. I am from Canada as well.
To answer your question about people who have had their cameras successfully fixed. I don't think I saw any reports to that extent here (I might be wrong, I read way to many different sources of this issue) but I did read about 2 or 3 reported cases in which the issue has been successfully rectified. One of those was in Netherlands, couple in the states and Ming Thien in Asia reported that his camera was fixed (maybe Nikon replaced the whole thing inside since Ming is a very well known photographer - I do not know).
