So I was going to the gym a few days ago and went to put it in reverse and it grinded loudly, my thought was that I wasn't paying attention and maybe clutch wasn't pushed in all the way.... tried about another 10 times and its started to grind about 8 times! I started it up today and put it in reverse twice and did it once again? Is the clutch going on it? Its a 2011 and still has the remaining bumper to bumper warranty, is anyone had this issue? I know the 07-09 had clutch problems
