If it does not happen repeatedly... then chalk it up to some random software glitch somewhere. If it persists and repeats.... time to visit the dealer.
The downside to all the electronic features and bells and whistles in these modern vehicles is that they all have their own software and I can state for absolute fact that there is no such thing as bug free, glitch free, software. Some may be worse or better than others, but they all are going to trigger some sort of malfunction or software exception at some point in time.
Having dealt with software engineers for many years in my career.. they generally follow a different mindset from hardware engineers... as they see any bug escapes as "no big deal" as they can simply patch out a bug and release a new software update to fix it. Problem is.. this slack and lazy approach to software quality does not work particularly well with most modern automobiles yet. In essence.. I find that software engineers tend to use "the field" as their debug QA team much more so than hardware engineers do.
A complicating factor for Honda and other manufacturers is almost all electronic systems they put into their modern vehicles are actually outsourced to other suppliers now days. Honda provides the specifications, acceptance criteria, and Service Level requirements for such systems.. but it is actually some 3rd party software chimps somewhere writing the code... NOT Honda.
Think of it this way... when your PC at home glitches on you.. the prescribed fix is to reboot it, then check the Event Manager to see what errors took place prior to the reboot to see if anything really nasty or persistent shows up. The same is true of our modern vehicles with literally dozens of different little computers all using different sensors and software to perform the features Honda intended, which is why a simple shut down and restart clears a wide range of little strange issues that can and do pop up.
