2015 Honda Accord
My windows, sunroof, trunk randomly open without any input from key fob
rain has flooded trunk once, trunk has opened while driving creating a dangerous safety issue
I have taken to dealer for service 6 times with no resolution Techs can not locate any problem
Filed a case with Honda America also with no resolution

 

welcome to the forum only info i have is that there may be another honda near your honda that may have the same code as you have and when they open their car, yours will do the same. a few other sites state the same, at home, key on the key hook, and go out to leave and trunk and windows, roof window all open and soaked from heavy rain.
