I don't mean for my first post to be a "me to", but the same thing happened to me this weekend. It happened as I was backing up. It got caught in my belt but luckily I noticed it right away. I was able to rock the Spyder back and forth to free it from the belt. The bolt holes in it had no damage so I assume the bolts just backed out. Took it to my dealer and they had another guard in stock and replaced it. I will be checking it regularly and would advise others to check theirs.
