Not really mechanical, but an "issue" nonetheless.
My wonderwheel switch was a bit "clicky" / sticky when rotating it. Felt like something was getting caught within. Brought it up with the tech when I had my 600 mile service done a few weeks back. They said they felt it too, and ordered me a new part. Part came in the following day but I didn't want to go back to the dealership so soon.
Anyway, ended up going in yesterday. Took an hour, replaced under warranty (so no cost), new wheel feels smooth and great. No complaints here.
