Canon Eos 7d Best Buy

Ken asks…Canon EOS Lens rattles when shaken?I have a Canon EOS 7D and with it came a lens that is an EFS 18-135mm. I got this lens about 1.5 years ago and it has never been a problem before. But now, when the lens is given a little shake you can hear a loose part inside rattling. The autofocus also gets stuck sometimes when I am trying to take a picture and I just have to give it a little shake to move the loose part and it functions fine. I am going to take it in to a Canon shop for repair
