Play in pedal body Vector 3

I have used Garmin Vector pedals ever since they came out with the Vector 1.  I currently own two sets of Vector 3 pedals, one for each of my two regular riding bikes.  Recently I got the sensation that perhaps the cleat had come loose from the shoe itself with it being VERY loose.  I checked the shoe, shoe and cleat were both in perfect condition.  I used another pair of shoes, same problem. This tells me its with the pedal itself and not the shoe.  The tension is adjusted the same for all pedals but this one pedal is causing problems.  Is there a fix and if so, what is the fix?
