My failure recollections:
Mine failed in the summer, a couple of days after riding a whole day in torrential rain, then being parked outside in more of the same. It ran OK all day on the next day (let's call it day two), on day three if coughed briefly while pulling off an Italian motorway. I put the momentary misfire down to it being a roasting hot day and crawling at 30 mph for a while on the motorway.
Day four - got me to the top of the Stelvio pass, so not exactly relaxed riding, but would not restart for couple of minutes. I put this down to altitude and heat of engine, or perhaps some dodgy fuel. Got to the bottom, filled with petrol, wouldn't restart for 15 mins. Then started and ran fine for the rest of the day, although my concerns meant Imissed th eplanned route through the Dolomites.
Day five - started coughing sporadically riding up the Grossglockner. Getting worse and worse, finally failed totally at the bottom. Breakdown recovery, dealers, new controller, no more problems. They gave me the old one too.
I butchered mine, to the extent of cutign through the cover on the base of the unit. There was no sign of any corrosion inside on the circuit board, but that's not to say that water wasn't the cause of the problem.
I have wondered whether the problem could have been unrelated to water, just a weak part. However, if the same part is use don othe rmodels with no problems, it would seem that mountign is somehow causing or contributign to the issue.
Perhaps the problem was a result not of failure of the unit itself, just the connectors (although as Wapping said earlier, the connector looked in good nick). Perhaps I should have tried the old unit now, before lopping the lead off.
I now carry a spare - it cost me £70-odd quid from a dealer.
While it will be impossible to establish definitively what proportion of bikes have failed, there are some indicators that it is a very common problem. Apart from anecdotal evidence here and elsewhere on the 'net, it seems BM's own breakdown recovery people carry spares as a matter of course.
