About 5 years ago I installed 8 sets of the Knape & Vogt GS4270 full extension, soft close drawer slides.

One set, the one on the most frequently used drawer, no longer fully closes on its own. When I give the drawer its normal push, it glides to about 1/2" from fully closed and then stops. The soft close mechanism does engage, it just doesn't pull the drawer all the way closed. A gentle push gets it closed, but it's a "manual close" i.e. I don't feel the mechanism taking over.

I can "fix" the soft close issue by fully extending the drawer (the standard full extension reset method) but this only solves the soft close issue for a day or two, probably some X number of usages.

I called KV tech support and other than "make sure all the screws are tight" and "make sure nothing has shifted inside the cabinet", he had no other suggestions. When I asked about lubrication, he was pretty emphatic about not trying that.

Unless someone has a suggestion, I think replacement may be my only option.
I've never looked to see but I'd presume there's a number of cycles
design limit -- possible it is just wore out. I also have never
investigated just how the self-close mechanism works...

I hope that 5 years of normal kitchen use isn't "designed in". In fact, it's
5 years of use by just 2 "empty nesters". I hate to think how often I'd be
replacing slides when there was 6 still of us in the house. :-0
