I thought I was exempt from this problem. The temperature turned a bit cooler tonight, 35 deg F, and I stepped onto the platform to climb aboard and couldn't believe what I heard. As soon as I heard it I did not have to even look down, closed the garage door, turned out the lights and went back into the house to drown my sorrows. I'll deal with it on Monday.
Oh, by the way, my camera took a few pictures of the evidence for discussions with my dealer. As you see from the one picture, just resting my foot on the platform, the back part where it is connected to the fender is completely unsupported underneath. There is a frame member there, but does not come into contact with the underside of the platform. The fender fully supports that part of the platform, clearly a flawed design. For those who don't have the crack yet, step forward away from the fender if you want to avoid the problem.
I hope my dealer knows about the problem so my anger is kept in check. We'll see if I can get the new design as a replacement. I'm somewhat glad she's only 4 months old, but disappointed that warranty is becoming common place (seat, fender, battery cover, . . . what's next). Just as long as I don't dig its own grave!!!
