Query: Error 99 and shutter problems are serious

I got a new 10D a few month ago. It just failed. I have not taken more than 500 pictures. I used only one lens Canon EF 24-70/2.8L. Today the shutter failed. One leaf of the shutter could not get back into place. So the camera shows "ERROR 99" and is no longer useful. Search on google will see so many posts on this problem. The shutter life is very short. Do not buy 10D until the problem resolved, or you will regret. I am surprised that no one addressed this here.
