Broken Radio Control

I have a 2005 with the factory stereo/cd player. The power/volume control knob appears to be broken. It is loose and kinda just flops around although it works perfectly. Can this be tightend up or repaired in any way? Has anyone else had this issue?

If your knob is broken , go to dealer and see if you can get a new knob . If that doesn't work , try a salvage yard .
