As 4x5 says, a call to CS is your best route. There is no recall per se, but in almost all cases where the customer has requested it CS has been sending out the rod, slide, and STS as replacements. Also as mentioned, not all bows have the problem. I don't think it's related in any way to a particular model so much as the way the TRG is adjusted or maybe some sort of burr edge in the middle. Afterall it is just a piece of molded plastic so almost has to have a seam in the middle.
When you call you need to push #3 (I think) on the phone for warranty service.
