Can of worms indeed. 2014?
Its not as easy as you think to repair. Its a laminated assembly. 1 1\2" or so aluminum tubes with 1/8" luan underneath, 1/4"plywood on top under the vinyl floor with beaded styrofoam in the center, all glued together using a vacuum press. Usually what happens is in an area of constant traffic such as in front of sinks, entertainment center, entry door etc, the glue bond between the plywood and foam gets loose from the traffic. Over time the foam compresses or comes apart, hence the soft spot.
I would be calling Rockwood, no matter what the warranty status is. This is a factory level problem/repair. It can be tackled yourself but its not easy and a total PITA. That is if it is not the result of something you caused, like a leak from lack of preventative maintenance. In todays world of environmental bs, they are forced to use low VOC and water based adhesives which are not as strong as the ones they replaced.
They could build these floors using better methods and materials but they don't. In this case extruded polystyrene foam and a thicker plywood would be a much better choice, but evidently they weighed structural benefit against cost and weight savings and cost wins everytime it seems.
