Canon EOS 1D mkii N- Streak in images.

[JestoK3]

Hi guys so I bought a used 1D Mkii N off Adorama and it was given a V rating. Everything was fine out of the box until I took the test shot revealing this white streak in most pictures. I noticed it was less noticeable with a flash but after tossing it into light room I was still able to find the mark.
But does anyone have any idea what could be the issue? Is it something I can possibly get fixed? or is it a sensor issue?

First the good news, the 1D Mk IIn is a great camera.  I still use one.  Love it.  The bad news, yours has a failing shutter.  If possible return it, otherwise Midwest Camera can probably put in a new shutter.  Canon can't.   Guessing $300 bucks give or take a buck or two.
