Canon 40D - ERR 99 :(
Well, I’m not sure what’s up with my Canon 40D right now. After just 3 months and ~15,000 shutter actuations, it’s dead. I put a fresh battery and any one of my lenses on, and things are OK for the first few shots. After 5 or so pictures, the buttons on the top of the camera stop working. Then, the shutter button stops working, and ERR 99 appears on the readout. After taking the battery out, putting it back in, the error is cleared. And then it’s good for a few shots before ERR 99 again 
Looks like I have a trip to make to Pro Photo Supply in Portland to see what they can do for me. I’m out of the 30 day return period, but still within Canon’s 1 year warranty. I’m wondering if I should have just bought the camera at a Best Buy, along with the extended warranty. At least they’d just swap me over the counter for a new one.
Update: Pro Photo says I have to send it back to Canon, and it should take at least 4 weeks to return
Update: Because Pro Photo sent the camera in, there is no way for me to call Canon to check on the service status
Update: 5 weeks and $14 in shipping charges later, I have my camera ..
