cars setting on fire is not solely a Honda problem - when we lived in Oz a friend had his Ford Laser spontaneously combust and car was totalled (luckily he wasn't in it). Also Ford USA have seen recent problems with their eco-boost engines.
To be fair to Honda, this problem can show up if water has got into the drivers door window control switches, which can happen if water is spilled onto the switches or if the window is left open in a rainstorm - both pretty unlikely. Basically this problem may also exist on other car makes as well, as car makers buy in electrical parts from specialist makers and this circuit board is liable to appear in quite a few other cars.
