I see what you're thinking, but Giant sell a lotta, lotta bikes, so either it's going to be very easy to establish there is a quality problem with some or all of their wheels, or it's going to be very difficult to do so.
Are your hub, rims, nipples, spokes, spoke count the same as the OP? Is the service history the same? Have they ever been trued or retensioned by anyone after leaving the factory?
Those are the kinds of terms around which you'd want to build a case that Giant has chronic wheel problems. It may be you're onto something class-action worthy, or it may be there's another explanation.
My gut says that exploring the causal factors is not going to be worthwhile for most people, and that simply replacing or rebuilding the wheelset or wheel will be enough.
