As if it wasn't bad enough to spend 3 weeks at the shop doing the recall, I had a key battery that went bad. Now I am getting this SOS inoperative button. Anyone seen it before?

C1600, there was another post I remember saying on the B-Class, the SOS button is not functional. I have not tested this.
