I had this same error but the results somewhat different. My images were entirely black.
I could however shoot video. Live view works fine. But I cannot capture a still image.
I brought it in and they suspect a broken shutter. They will confirm soon (I hope). The camera is under a year old.
I was using a 3rd party grip. I have since bought a real Nikon grip thinking this might be what caused the error. But that being said, I fail to see how that can be. Unless the grip caused a short, what else could a grip to to cause a shutter fail ? Seems too much like a coincidence to me.
