I have an M4900 and did have a recall on the step a few years ago. The dealer ordered me a kit and when I got it, put it in my toolbox and there it sits. It was a brace for the step, but since I'm the only one who ever uses it, and not really a heavy weight, I'll take my chances. After 11 years of ownership, it's as strong as when new----seems that way, anyways.
