This is a really serious issue. The fact that it happens at all means it could bite you really badly one day when you do need to use it. Also it probably happens “a little” at moderate temps, so one day when you see -20C it might bite you big. I would definitely get it fixed.
It sounds like water in the cable and this needs to be fixed – by a legal adaptation of the front end, or by an illegal adaptation of the front end. And – for non teflon lined cables – suitable lubrication – not WD40 whose temp range is unsuitable for GA.

But it’s a normal serious issue 
This is just too funny. It’s in fact the technical reason why the space shuttle blew up in mid air. They new they had a serious issue, but they fixed it by “normalizing” it

and is not a lubricant in the first place, contrary to what many people think…
90% of the GA maint business would disagree 
Tri Flow or LPS (free advertisement for those companies. Any pleased rep is free to express his gratitude by using the donate function on the upper right of this page, thanks) are an example of real lubricants.
WD40’s effect as a lubricant is very short lived, and it is more at home in one’s garage to remove corrosion from the lawnmower or free bolt threads on similar machinery… of course the stuff is way cheaper than the above mentioned products. Guess some of those 90% disagreeing businesses will likely also charge a hefty price for this popular “lubricant”…
