Headrest / Roll Bars Popping Up - 2009 CLK550 Cabriolet W209

The headrest / roll bars have been popping up every 3-4 weeks while driving. I don't have any problem resetting them. It just keeps happening while I'm driving on smooth roads, no bumps, etc...

FYI, the 2009 CLK550 does not have an up / down reset button on the dash console as the earlier models do. This model requires unlocking and physically pushing the headrests / roll bars back down and locking them in reset position.

Is there is a relay that could be replaced? If so, which fuse box would it be in and which relay in that fuse box? Any thoughts or suggestions on this would be greatly appreciated.

I have the same issue. In my case, it seems to happen less frequently when the outside temperature is cold, below 40 degrees. As the outside temp increases it happens more frequently, which makes me think its a faulty electrical relay. Would like to know the location of the relay so that I can replace it.
