Sorry, I have no better quantification beyond anecdotal evidence. Ken Y up there has some experience with Shimano dynamo hub failures that he may wish to share. Besides his experiences, I have had at least 2-3 returned after less than one winter of commuting. I often buy them as prebuilt wheels, so warranty is usually not feasible unless I want to disassemble and rebuild a wheel for free.
The main problem is that the electrical system is sealed with a substance that resembles plumber's putty. This seal deteriorates and crumbles, I assume as a result of the salt and other ice melting chemicals they use on roads and paths around here, combined perhaps with getting brittle in the cold. I still think the Shimano hubs are a good value, but I now try to discourage folks from using them much in the winter slop.
