During my recent recall repair by Ed Morse Honda in Riviera Beach, FL, I was advised that the rear tailgate sensor was reported as "wet". I do the maintenance myself, so I passed on a repair at that time by the dealer. Today, I researched what might have failed both online and with my Alldatadiy subscription, and accessed the part. Indeed, the Liftgate Control Module was molded and need of repair/ replace. However, I have grandchildren now, and during the removal - realized that in a water accident or other hazard where power is lost, there is NO WAY for rear passengers to exit the van by the rear tailgate. There is NO readily accessible latch or pull to open the tailgate from the inside, and NO key nor latch available from the outside for outside assistance. Additionally, if a child is in need of exiting the rear tailgate, there is NO child safety pull to allow them to exit. During my research on how to repair the vehicle, I saw that this is an ongoing issue for this model of Honda. I like my 2018 Honda Odyssey very much, it is my second Odyssey (the first was totaled in a T-bone accident, where both wife and daughter walked away), but I believe a recall is needed for the water issue affecting the Tailgate Control Board for the short term, and safety mechanisms added for the long term. Note: I have images, but the web site is NOT allowing uploads of any.jpg nor.pdf's at this time.

The Control Module for the Power Tailgate experienced total failure due to water damage, documented by the servicing dealership (attached service invoice) and demonstrated by the attached photos. The point of water intrusion could not be determined definitively, but cracks in the bonding location between the roof, rear driver's side exterior D-pillar panel, and tailgate surround are the likely culprit (photos attached). Failure of the Module resulted in an unusable tailgate, except for a single manual lever on the inside of the vehicle, accessible behind a piece of plastic. It also resulted in a ceaseless, loud, constant beeping on both the inside and outside of the vehicle when traveling at over 1 mph. This vehicle has never experienced an accident.

Part of the interior frame under the dashboard disintegrated. This was discovered while Honda was fixing a different recall involving electrical components.

I'm constantly having issues with my right sliding door on my 2018 Honda Odyssey, opening after it's been closed and I'm constantly getting beeping alerts on my dash saying problems with right sliding door while I'm driving. It's been happening for a while now. Fortunately, the door hasn't opened while I'm driving on the road yet, although it did occur once while I was backing out of my driveway. I notified the dealer before which they told me there was no recall on the door and they would have to charge me money to try to replicate the problem and if they found nothing wrong, I would be out of that money. There was a recall on the doors back in 2018, NHTSA campaign number: 18V795 but I didn't receive a recall notice. The alert on the dash happens almost daily at random times.

Water getting into rear liftgate control module. Had to replace seal and module.

Power Tailgate is not functioning and the trunk opens on its own. Yes, available for inspection. The trunk opening on its own puts the safety of everyone in the car at risk. I had the same issue 9 months ago, the dealer charged me $1200 to fix it. The dealer inspected it and stated it was due to a water leak that damaged the control module for the Power Tailgate. Nothing prior, a "Power Tailgate Problem" warning appeared on the dashboard, and the Power Tailgate stopped working.

A water leak above the tailgate control module flooded it to the point that it operated erratically and would raise and lower the tailgate randomly or not work at all. I plan on replacing the module myself but will retain the old one. Anytime the entry or exit points on a vehicle open randomly cannot be a safe condition. The dealer charges $130 for any inspection or diagnostic so no I am not paying them to tell me something is broken. The vehicle currently is showing a "Power Tailgate Problem" and a yellow box with "TAILGATE" in it on the dash display and is currently unresponsive to any input that would operate it: remote, tailgate buttons, and driver button. The power locking system is still operable. The Odyessy forums clearly describe multiple occurrences of this failure and the culprit is a water leak in rear window or rear section of roof trim strip on the drivers side. My module did have water in it when I opened the plastic case it is contained in. Cleaning and drying it restored operation for about 3 days. Thanks for your help!

Rear tail gate will not open even manually due to water getting inside of control module due to faulty design which causes water to go into the module and fry it would open and close randomly when it would rain now it has stopped working all together no indicator on dash anymore I guess this last rain finished it off terrible design very disappointing with Honda this is a major issue that needs to be fixed

The rear lift gate is not opening. The lift gate motor and latch have been replaced. The lift gate module seems to have water/moisture after a rain storm causing the gate to not open. Their is an error on the display saying there is a lift gate error and the car is beeping while driving.

Power tailgate problem. Middle both passenger side door did not latch. Power tailgate cannot open automatically. It happened recently, and happened every year as far as I remember, when raining season, or winter time. It just happened few days ago. Passenger side door did not latch. I was driving with baby in car seat, on freeway, when door latch did not lock properly. My wife had this incident as well, and called Honda dealer, and they may or may not repaired the latch, and we rarely have this incident anymore after my wife called Honda dealer, cause she freaked out door was open loosely while driving. But on left side, occasionally cannot open or closed, not as extreme as before we complained to dealer.

On the way home, the rear door controller was damaged and the rear door opened by itself. So I pull the car to the side of the high way and tried to close the rear but couldn't. I drove my car to my home with the rear door open. It was a crazy experience to me.

Water intrusion on the driver side rear panel has caused the power tailgate command module to short out twice now.

- Rockledge, FL, USA

Both of my passenger sliding doors failed, resulting in both of them opening while driving with my children in the back seats. In August 2022, my driver side passenger door swung wide open while I was driving the car, with the error on the dashboard showing door open. Took the car to Honda Dealership, who stated that the door latch failed and replaced the door latch. Now, a year later, in October 2023, the same issue happened on the passenger side. The door swung wide open while driving, with the same error appearing on the dashboard. This time, Honda refused to fix it and demanded that we pay $800 for the fix. How do latches on both doors fail?

Every time when it rains, the power tail gate fails showing beeping noise from the rear and on the screen and unable to lock the doors. Had to replace the power tail module couple of times so far and still problem persists. The Honda dealership mentioned there was a leak, repaired and replaced the module, inspite of the fix priblem still persists when it rains.

The power tailgate on my 2018 Honda Odyssey EX-L started opening and closing on its own, seemingly at random. The latch would not cinch and the gauge cluster reported an opening attempt while driving on the highway. This failure cascaded and ended up bringing every device on the B-CAN network down, including the instrument cluster, heated seats, power sliding doors, ADAS systems including FCW/LDW/LKA and various telltales and buttons on the dash. Upon disassembly of the interior to expose the affected controllers, I discovered that the power tailgate controller was full of water. There was enough water in it to cause arcing of the power and CAN terminals. I traced the ingress path upwards and discovered a crack in the seam sealer on the roof, underneath the left roof rack rail at the very rear of the vehicle. Water enters under the roof rail, drips down the door hinge, then drips down the body to the cup holder and directly into the controller. To remediate I had to replace the damaged controller and apply seam sealer underneath the roof rail at a cost of approximately $200. I called the local dealer to attempt to report this to Honda but was unable to find the appropriate person. Over a dozen people have reported this issue online and there are pictures of the issue. I posted pictures to one of the links referenced below and have additional pictures. I believe this is a manufacturing defect and not caused by age or use of the vehicle and there is strong evidence it affects a lot of people. The issue will be particularly prevalent when the vehicle is parked outside on a downward incline. I work in a related industry on embedded devices that must meet functional safety standards, and I believe an issue like this would lead to a mandatory safety recall.

After rainfall water is leaking into the rear fuse box compartment located behind the 3rd row seats and causing the tailgate control module and other parts to fail. The tailgate does not have any power and cannot be opened or closed with the fob or the push buttons located in the tailgate or in the dashboard area. The tailgate cannot be locked as the latch does not engage and it can be very risky to drive the vehicle as the tailgate might come open while driving. There might be some opening on the roof of the vehicle from where water is leaking into the fuse compartment and causing this hazardous situation.
