Definitely a weak point on these bikes. Life expectancy seems to be around 50,000 miles or even significantly less in quite a few cases. Try to get them to take a few pictures to see if it's just a nicked wire or if the whole thing is burned out and black like Finn's.
I think the possible solutions would be weaker magnets, higher quality wires and epoxy insulation, or a series regulator. The last one would be the nicest as you wouldn't reduce the electrical power output.
