since upgrading to 2.0.3 I have noticed three issues that may just be coincidence (or that I am now noticing them now that others are seeing/reporting these similar issues) - 1) I have the same focus issues, where it appears to focus lock but the image comes out way out of focus; 2) suddenly started getting the "error 30" or in some cases the camera just goes blank without any errors, after which I have to pull the battery to get the camera to come back to life; and 3) the LCD and power timeouts are not consistently working (LCD is staying on until I take the next picture, which may be minutes in some cases). The error 30 is most concerning to me right now, but wanted to see if any others are getting this only after upgrading to the newest firmware?
Error 30 indicates a problem with the shutter. Do you think your camera might have enough actuations on it to start causing problems with the shutter? The lifetime ratings are really only an estimate, and the shutter can indeed go a lot earlier than its rated lifetime, or if you take a lot of photos and have owned the camera for several years, you might just be out of life. I figure I've had about 35,000, maybe 40,000 shutter actuations on my 7D in the last 10 months. The shutter is rated to 150,000 actuations, so someone who has owned their 7D for longer and takes enough photographs could indeed be reaching the end of their shutter lifetime.
