Pondrader hopefully the resolve the issue quickly. If you send it in and its working good you should get it back better not worse. I sent mine in on a Monday and had it back on Friday I sent it to the New Jersey plant. Good Luck.
They never do and I have sent gear to Toronto, New Jersey and Newport News. Too much detail gets to many people thinking

a Actually these days I don't really care. Calibrate and electrical adjustments are good enough for me as long as it works.
True as long as it works I'm OK with it This is the second camera I had to send in the first was 60D that had a hard time locking focus I received pretty much the same response and when I got it back the camera was ten times better I'm hopping this one is the same when i finally get to really use it.
