Query: This needs to be recalled!

This Black & Decker CBG100S Coffee Grinder needs to be recalled!Mine worked just fine for about 6 months and then it malfunctioned the last time I used it. It ran without me pushing the on button and it continued to run without the lid in place. I think this is very dangerous! I have been using it about 4 times a week, and only for coffee beans. It had never been dropped or anything. It was clean and there is no reason for it to have done this.
