2020 Honda Odyssey UNKNOWN OR OTHER

After a heavy rainstorm, the power tailgate motor stopped opening or closing the tailgate.

Sunroof exploded while driving on the highway.

I was driving and the message Power Tailgate Problem popped up on dashboard of Honda Odyssey 2020. When I got to my destination I tried to open the trunk and it would not open. I took the car to Honda and they said there's water somewhere that caused problem to the tailgate. I spent over $1,000 to fix it and two weeks after getting the car back, that same message popped up and the trunk would not open again. I did research on this and found out that this is a known issue/defect for all 2018-2021 models. Honda did not take any responsibility and blamed me for not taking the car to a body shop to fix whatever issue that's causing water to infiltrate. I found that there has been class action lawsuits involving Honda tailgate issue for a defective seal on 2018-2021 Honda Odyssey models that allow water to infiltrate, yet Honda will not recall and fix it.

Summary of the Problem: The power tailgate motor on my 2020 Honda Odyssey has failed multiple times, causing the liftgate to stop midway, refuse to open, or abruptly close on its own. This failure creates a safety risk because the tailgate can unexpectedly drop or close on adults or children standing underneath it. Detailed Description: The tailgate motor on my 2020 Honda Odyssey has stopped working correctly on three different occasions. I have taken the vehicle to the Honda dealership repeatedly and have paid hundreds of dollars for repairs, yet the problem keeps returning. The tailgate will randomly stop while opening, won't fully lift, or will close unexpectedly and forcefully. This is especially dangerous when loading children or cargo, as the tailgate can fall without warning. After researching online, I found many other 2020 Odyssey owners reporting the same tailgate motor failure, indicating that this is a widespread issue rather than normal wear. The repeated failure suggests a potential design or safety defect. I am requesting that NHTSA investigate this recurring malfunction as a potential safety issue and determine whether a recall or corrective action is necessary.

Lift gate sags. Lift gate sporadically closes without any activation. It does sound warning prior to closing. Lift gate has come down on person causing bruises more than a few times.

The sliding doesn't close all the way or it will open on it own. I will warning when I am driving about the sliding doors

The radio/screen will go blank when I am driving.

Rear tailgate doesn't open with keyfob or with switch on the back door. it had to be pulled hard to open in manually and pushed hard manually to close it. There are so many incidents reported on line for the same. The fix seems be a control board (Which gets bad due to water getting in the compartment (or on the board). We have talked to Honda - as per them there is no active recall on this.

Tailgate Control Unit failed due to water entering through the seals of roof seal which resulted in damaging the functionality of the tailgate. Failure to open. I noticed one day that the tailgate would not open (the back hatch). My Honda dealership got the vehicle in rather quickly (One week). Dealership stated they have never seen this and requested repairs of over a thousand dollars. After further research on the issue, I noticed that there are multiple class-action lawsuits with multiple law firms. This is not an isolated issue. However, I am glad that the dealership was able to get my vehicle in and fixed in an appropriate amount of time. The worry was that just one day, the back tailgate quit working and there was no manual way to open the vehicle in case of collision, fire, or water incident and used as an escape route. With multiple class action lawsuits on the same incident, I believe this incident needs to be followed up on. Solutions: Revist the type of seal Honda is using. Move the control unit to a different location within the vehicle so the control unit will not become waterlogged and damaged. Lastly, provide a manual unlocking and opening mechanism for escape out of the rear tailgate if vehicle is involved in a collision, fire, or water event.

Rear door would not open with key fob, button on the dash or the button on the rear door. Then it randomly opened one morning and would not close. Through research I found out there is a problem with water leakage, the vehicle is not properly sealed. Resulting in a damage MICU. I was able to replace the MICU and the rear door works now. I believe this is a safety concern, how can I drive with the door not latching. When I unplugged the MICU water poured out and you can see rust in the fender well where the MICU sits.

A latch inside the driver door of the car broke and my husband was unable to exit the vehicle. There was no reason for this part to break, no collision or rough use of the door. We just drove from our home to our destination without incident and the door would not open when we arrived. The dealership had to replace the broken part.

I believe the idle start stop malfunctioned. The three times this has happened, I have been at a stop light and when I released the break and attempted to accelerate, my car turned off. It took several tries to get the car started and I felt very unsafe. In researching online I've discovered that I am not alone and am concerned that Honda hasn't had a recall to address the problem. Are they waiting for someone to die or be severely injured before addressing the issue?

My backup camera is displaying system failure. It is not working. Makes Backing up less safe I contacted a dealer and was told my vehicle is NOT in the recall There was no inspection. It was working when I left the house. And stopped work before I got home. No other warning or other symptoms of the problem.

When at a stop light at a busy intersection the idle stop feature would not restart the engine. The vehicle became stalled in the middle of traffic and I could not restart the vehicle for approximately 8 minutes. A transmission failure warning came on the screen and I was unable to operate anything in the vehicle. This could have caused me to be hit by oncoming traffic or rear ended. The vehicle has been inspected by the dealer and they were unable to reproduce the problem. This has happened a total of 3 times within the last 3 months.

I purchased my 2020 Honda Odyssey 3 months ago. We did notice that part number 72650-THR-A12 the rear door latch was carroded. The dealer had told me not to be concerned. Well I have been unable to drive my vehicle because I am waiting for that part which is on national backorder. The incident happened two weeks ago my sliding door opened while driving with my kids in the car. I had to pull over to try to close it I thought it was a fluke. Turns out I couldn't get it to stay closed. I had to drive it back home with the warning lights that my door is open. I can't get it to close at all or lock the vehicle while driving. There should be no reason why the inside of my door is all rusted and carroded. Not sure how water is getting in there. This leads to a failed door latch which then leads to the sliding door malfunction. The part is on backorder which makes me think that there are many other people experiencing the same problem.

my rear entertainment does not show dvds playing however when I Insert a dvd I hear audio but the bluray rear entertainment appears to be stuck in loading setting and does not show a picture. Honda said there is a recall for this issue however My vehicle is not listing the recall. It is distracting to the driver and passengers causing stress.

Occasionaly car will not start of up after Idle Stop engages. Collision warning flashes then leaves us stranded in intersection. Very Danagerous.

Stopped at red light. System to stop the engine to save fuel engaged. When light turned green the car would not restart, stranding the vehicle at the intersection.

The right-side sliding door for the rear seat row has a recurring malfunction. When the vehicle is locked and not running the sliding door will open a small bit, all by itself. It will remain stuck in this position and the electrical sliding door mechanism will not operate it. No one can exit or enter the vehicle using that door. The door can be forced to the full open position with substantial exertion by an adult male. It will then close and the electrical opening/closing mechanism will work alright for some time until the problem occurs again. This vehicle is available for inspection upon request. The vehicle dealer service department said they had seen this problem before in other vehicles. This component of my vehicle has not been inspected by the manufacturer, police, or others. When this problem occurs, a warning message is displayed on the vehicle electronic dashboard saying "Right sliding door problem."

While driving the infotainment system will go completely out. When this happens you lose all additional safety features (back up camera, lane notifications, etc). This also becomes a distraction to the driver as when the system goes out it make a loud noise or will have a continued crackling noise which is highly distracting to the driver. I have seen a number of complaints online about this issue and have experienced the outages almost daily while driving the vehicle.

The auto idle stop automatically turns on when the van engine is started. I was stopped at a stop sign while trying to cross a dual lane highway (55 mph speed limit). Was not aware that the auto idle stop had shut off the engine. When I had an opportunity to cross the highway I let of the brake and pressed the accelerator and the engine was attempting to start and felt like we were going to be struck by cross traffic before the engine started and we were able to cross. I am aware that this feature can be turned off. But it has to be turned off each time the vehicle is started. Needs to be a way to permanently disable this feature.

The Honda Idle Stop feature is the issue. My wife drives this car and on at least 20 occasions, the car shut off when she was stopped at a stop light when Idle Stop was enabled. The car shuts off when she tried to accelerate once the traffic light turns green. The car then has to be restarted. This is a safety issue because cars behind us could easily rear-end our vehicle since the stop light has turned green and cars are moving. Honda claims that they cannot replicate the issue but it is clearly a large issue with the Idle Stop feature. It seems as if the vehicle does not have enough power to get the engine back to normal mode and therefore it shuts off. Most of the time that air conditioning is running so perhaps the extra load from that contributes. Regardless, this is something that needs to be fixed quickly.

UNKNOWN My 3 year old’s hand was crushed in the sliding door. The door closed completely, latched and locked (beeped). The door did not recognize resistance when closing and did not reopen. Medical treatment is forthcoming. The picture attached was taken approximately an hour and a half after the incident.

TURN SIGNAL SOUND INDICATOR NOT AUDIBLE WHEN DRIVING. ENGINE NOISE, OPEN WINDOWS, RADIO, DROWN OUT THE SOUND OF THE TURN SIGNAL BEING ON. TURN SIGNAL LIGHT INDICATOR WORKS BUT SEEMS TO BE NOT ENOUGH TO REMIND ME TO TURN IT OFF.

CRACKLING NOISE FROM FRONT WINDSHIELD OR DASH AREA MOST FREQUENT WHEN THE VEHICLE IS MOVING BUT CAN SOMETIMES BE HEARD AFTER COMING TO A STOP.
