Take it into the dealer asap. It could be a defective belt although that is very rare or it could be a problem with the belt sprockets which is a more serious issue.Hi all. Just broke 1700 miles today. When I got home I notice Chunks on the rear Rim. Looked at the Belt, I can see Chunks coming off the Cogs. Anyone else notice this?? I'll see if I can post a pic later.
