I've my Jazz since nearly a year and haven't noticed any electronic gremlins by default.
Sometimes the central navi/audio... system takes a bit longer to start up. I can live with that.
The ACC (adaptive cruise control) is acting a bit too early on twisted roads while it's perfect on the highway. I don't regard it as a fault that Honda has to solve, it's just the way it is.
While I do understand that people want perfect cars it should be noted that these complex electronics in todays cars to have their limits even if a 4-letter guy with his 'magnetic' carmake wants to make us believe that there are no limits.
Buying a car of one of the VW brands by a very picky person is a pretty perfect match.
