I was out today and a swivel rack swung and hit my sister-in-law in the head! It had a couple of wake boards on it. I thought that maybe I didn't have the pin pushed down good. But I was pretty sure it had clicked. So got some tylenol out of first aid kit and she moved and another girl moved in that spot. Five minutes later it did it to her! I know the pin was down that time. Starting looked at it and pulling on it and I could get it move out of the locked location. This is on a new 2014 Mondo? I thought they were fixed on new models? I am assuming this is warranty?? Has anyone else had this problem on a 14?
