It sounds to me like they have narrowed the nose down to the capacitors. I would guess that they will have a solid fix for this.
Remember guys, the gap between identifying the problem and fixing the problem can be big. The only thing they can do to bridge the gap is attempt a band-aid until they redesign the part. Band-aids are very frustrating because they only mask, and never fully fix the problem. I am sure a new part, or a part to dampen the noise will come soon.
We only have a couple thousand miles at best on my wife's truck, but there hasn't been any issues at all.
