I noticed mine starting to stick last weekend.
I found some Dielectric Silicone spray at AutoZone $2.99 for the can.
Sprayed some in a paper cup, dipped a Q-tip into the cup, applied it to the inside portion of the assembly and the underside of the ring of the cup holder. This is the same spray that I used on the convt. top pinching problem. You don't have to apply a lot of it, works great. I will start to apply this to the cup holder once a month as I do the convt. top parts.
