On a rainy day, the power tailgate began to malfunction. First it would open part of the way, beep, and then close, then when trying again it would go move back and forth on its own, and then close. Trying it again later, however, it completely stopped working to the point where we had to manually force it to open and close, only the latch would work. The heads-up display showed power tailgate error. On my attempt to troubleshoot I found that water had leaked into the area behind the driver’s-side rear inside body panel where the rear control module and fuse housing is located, which I noticed was covered with water. I was able to partially dry this. Later on the rear tailgate started working again briefly but the problem returned and now it no longer works. I contacted Honda USA about this issue and they told me there is no recall for this, however when I did a google search this issue immediately pops up and seems to be a common manufacturing safety problem that has not been addressed.
