Hello.I bought mine from Costco and returned it, but will probably buy it again.I would send it to Canon as you should still have a warranty on it. Also, when they fix it do ask what the issue is.
I think I am going to return this. My concern is if I get another one and the same camera what if it happens again after the 90days or one year, I then have to send to Canon and pay for the fix. This seems to be a known problem now with this camera...
