I know that Roush told you that a little fraying is normal....I'm sorry, but if they accept that as normal, then something is wrong. If your car was a few years old and had several thousand miles on it, it would be a different story. But, as new as your car is, your belt should not have that much fraying on the outside edges.....something is either misaligned or as other have said, an idler or idler bracket is flexing and allowing the outside edges of the belt to ride/climb one of the pulleys. I'm not an expert or a certified engineer, but I've been around enough belt driven equipment in my life, to know that something is not as it should be with your belt, pulleys and idler/tensioner.
