2020 HONDA ODYSSEY Structure Problems

The contact owns a 2020 Honda Odyssey. The contact stated that the passenger’s and driver's side sliding doors were frequently not opening or closing as designed or intended. The contact had noticed the failure approximately 2 years prior; however, the failure was intermittent but had since gradually become more frequent. The contact had taken the vehicle to a local dealer, where it was diagnosed, and it was determined that the pinch sensor needed to be replaced. The vehicle was not repaired. The contact was no longer using the sliding doors out of concerns that the doors would remain open. The manufacturer was informed of the failure and referred the contact to a dealer for assistance. The failure mileage was approximately 55,000.

This is now the second time that we are having a rear hatch failure. with about 37,000 miles on this van, the control module shorted out due to water getting into it due to a bad seam (according to other Odyssey owners who are suing Honda for this). We could not get the hatch to open or close, so I paid the dealer to fix it. Honda did give us a check after the fact to cover some of the bill. Now, with less than 51,000 miles, it has happened again. The hatch will not open or close. In the event of an emergency, this is a major safety issue, to be potentially stuck inside the cabin. The hatch started going up and down randomly, and we could not control it. Now, it won't go up or down. This van is is a mess. Not only does it have this issues, but the rear back up camera still does not work, even though it was recalled...they would not honor their recall, and the brakes occasionally come on without cause, when going around a corner and there is oncoming traffic. It thinks that we are headed for a collision, and it's another safety problem here in the northeast. Honda needs to own up to their quality problems relative to these three safety issues.

The auto slide door latch will not disengage. The rear passenger door cannot be opened electronically OR manually.

Driver side rear sliding door will not open even when the automatic release button is disengaged. Some could be trapped in an emergency or I am worried that if it opens I will not be able to get it closed.

The rear hatch will randomly close after it is opened. The hatch will not stop closing if someone is standing under it. Several times now it has closed while someone is getting something out of the back and you can not make it stop without quickly getting out of the way and pressing the button. Both, myself and my wife have been hit pretty hard on the head by the hatch closing on us. This is a HUGE safety concern as I have children that could easily be harmed by the sheer power of this hatch. I have had the issue inspected by an independent shop and was informed that it would need both new power struts at a cost of over $1,200! The van is only 5 years old with 75,000 miles! There are no warning lights, messages or problems prior to the failure.

The power tailgate continues giving issues. I made the first repair about 1.5 years after purchasing as a new vehicle purchase. Now a few years, after the first repair, I', seeing the same issue. The power tailgate stops working and makes all the warning lights on my dashboard light up and drains my battery. During the last repair, the tailgate power unit was replaced as water gets into the compartment and causes damage. Initially it affected the driving assistance, the power steering system and lights as they were all acting up, with the dashboard full of warning messages, when the tailgate initially stopped working.

Top left rear exterior seam/seal on the top of the roof, under the black strip that runs front to back is leaking inside the left inner side/panel of the trunk, leaking water into all electrical components (break/turning lights) as well as the left rear seatbelt mechanism, soaking seatbelt, rendering it unusable. Could be a potential fatality in case of an accident.

I have had 3 Power Tailgate modules fail due to water leaks in the rear panel or window of the vehicle. I have had 2 leaks repaired and two modules replaced within a 6 month period (June '24 and December '24). 6 weeks later (Feb 14, 2024) have had the 3 module fail due to water intrusion following a heavy rain.

After any kind of weather event that produces water (rain, morning dew, snow melt), the car battery is dead the next morning. It jump starts the following day and will be drive normal until it sits overnight and the dew settles back in. There has been evidence of water leakage from the rear cargo door and the power door does not function. The only way to open the door is by removing the plastic cover and utilizing the mechanical lever on the inside of the door. The problem is a daily occurrence with dew and other water events. We have not gone to any automated carwashes, strictly handwash the car. No warning lights have been produced.

Sliding door stopped operating as a result of "badly torn inner bushings" which required the door motor and control arm to be replaced. This occurred just from normal use of the vehicle. At certain points, the opposite door also began to exhibit the same symptoms as the other. Furthermore, this problem did not just happen overnight, these components should be made part of a normal inspection just like the cabin air filter. Why is that inspected but the bushings of a sliding door are not? Could it be so the manufacturer or service department is hoping for these components to break so that it can gain business and work?

The rear hatch door closed with me standing under it and I injured my arm trying to stop the door from closing on me. The door will not stop closing even with a person there. This is very dangerous! The mechanic said that we need to replace the rear struts- this car is only 3 years old!

There is a water leak in the factory seals of the rear tailgate which causes the Power Tailgate Control Module to fail. The tail gate can no longer be closed/latched and requires replacement and sealing of the water leak.

I have had 2 major issues, the idle stop feature has multiple times caused my car to stall. It has even happened on the highway during traffic where the car went into idle-stop mode and would not restart the engine. Last week it happened again on a major road and the only way to restart the car is shift to park in the middle of a busy 4 lane road, turn off the car completely and then attempt a restart. The other issue was with the rear sliding door, my 3 year old son closed the automatic sliding door by pressing the button and his hand was crushed/ stuck until I was able to reopen it. I have called Honda who told me I could have it looked at but it would cost me for the diagnostic and repair if needed due to the fact that it was one month past their 3 year warranty period.

On 18 January 2023 the tailgate on our 2020 Odyssey refused to open. Neither the inside switch nor the outside switch does anything. I crawled in the back and checked the fuses and both are good. I also discovered that the emergency tailgate release did not function. Took it to the dealer, Greenway Honda in Florence, Alabama, an hour from home, and they weren't able to find the fault with a cursory check and a reboot of whatever computer system is applicable. They said they need to keep it for at least a half day and "really tear into it." But we could not leave the vehicle at that time, having no transportation home. Eventual diagnosis determined the tailgate control module, the tailgate closure motor, and the tailgate latch had all failed. Parts were on backorder and no estimate on availability. After I contacted Honda corporate the parts suddenly became available at the dealership within a few days. Repairs were effected on 27 February at Greenway Honda, Florence, Alabama. We were without the full use of our vehicle for approximately six weeks. Occupants could become trapped in the vehicle if the front doors were disabled in a collision and electrical power was lost, rendering the sliding doors and the tailgate inoperative. The emergency release lever also would not function and this could trap occupants completely. Examination of the tailgate electronic control module shows water infiltration which conceivably shorted the closure motor and jammed the latch, making it impossible to open the tailgate. Photos of the failed electronic module were provided to the dealership and to Honda corporate. The failed parts are in my possession and are available for inspection.

Power Sliding Door Reverses Direction When Closing as if something was in the way. This happens intermittently for both doors. We have to force the door close by passing the safety system. I know for the 2018 and 2019 models Honda. https://static.nhtsa.gov/odi/tsbs/2020/MC-10171536-0001.pdf Dealership is not able to see the issue with the car. I know this has been an issue with Honda Vans.

The contact owns a 2020 Honda Odyssey. The contact stated that the vehicle was leaking water from the roof seam near the driver’s side rear of the vehicle. The leak caused water to form a puddle in the trunk tray compartment of the vehicle. The contact had taken the vehicle to the dealer who resealed the roof seam. The manufacturer was made aware of the failure. The approximate failure mileage was 23,900.

Mileage: 23,900

While driving on a surface street at approximately 35 MPH on a 100+ degree afternoon, the glass moonroof suddenly exploded. I did not observe any object striking the car or the roof. The shade was closed, so glass did not enter the cabin. However, driving the car above 30mph became impossible due to air impinging on the shade and making it more likely that the shade would open and glass would fall onto me.

The contact owns a 2020 Honda Odyssey. The contact stated while driving at an undisclosed speed, the warning message "Lift Gate Open" illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the lift gate was fractured. The vehicle was repaired; however, the failure recurred. The vehicle was taken to the same local dealer, where it was diagnosed that the striker plate needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the local dealer but was not diagnosed or repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was approximately 13,000.

Mileage: 13,000
