I have worked with my local dealership to the point that I gave their Tech/Mechanic permission to drive the car home, etc. He drove it for a week and of course none of this happened. We drove around together with computer hooked to car trying to get it to replicate the issue, nothing. They are aware and they have not found what causes it. My mechanic said that all Honda Mechanics have a board like this that they chat on and none of them have been able to pinpoint why this happens. Before I can get my car to the dealership it would clear itself. Since this try by my mechanic and dealership it has happened twice to me. He told me to log my speed, weather, etc. and both times it was different. Only that that is happening each and every time it occurs is that I am using cruise control. I am hoping at some point they figure out what is causing it.As mentioned earlier, when a problem occurs on a single component all the Honda Sensing functions shutdown producing a plethora of warnings. The real problem occurs when the diagnostic code doesn't get stored, so when you restart the vehicle the dealer has no idea what happened. This is just bad programming on Honda's part.
Your best shot at resolving Honda Sensing problem that goes away when you restart the car is to drive it to the dealer while the issue is occuring. Don't turn off the car and have the tech plug in his equipment to find out what's going on.
