I had a team many years ago who mounted their speed controllers next to an open frame transmission. As the gears wore themselves in, the metal flaking off, landed right in the speed controllers. One after another died from this "metal fatigue".
Yes, we have seen damaged controllers with metal debris inside, including one at CMP. I have some photos, but we could use some better ones for education (I'll ask RMA to get some good shots). I should also add that this year NI's RMA process was very lenient, but we should expect that in the future returns due to contamination may require charges for cleaning and repair.

Attached is one photo from CMP showing debris - inside the chassis had the same coating of plastic and metal bits.
