On July 4, my vehicle suddenly shut down. The dash lit up and then the engine just died. This happened twice that day. And again multiple times on July 9. The battery was replaced recently.

Multiple times the engine has totally shut down due to the auto idle stop system power loss. I have had the battery replaced a couple times and had the Honda dealership do the software update and I'm still having issues. This is a major safety issue as the car unexpectedly shuts down and takes a minute or so to get started again causing traffice backups.

The auto Start/Stop feature doesn't work as needed. It will randomly lurch, turn the car off make me put it in park and then have me restart it. Sometimes the car does not start right away and I am stuck on the road until it decided when and if it will restart. Myself and my family of 5 are not stuck in the road scared of getting smashed into by other drivers unaware that we are stopped or anticipating for us not to be stopped in the middle of the road. I really dont want my family to go to the hospital or die because of this nonsense. Sometimes it doesn't fully shut off but will give error warnings like collision mitigation assistance even though there is nothing for it to mitigate. There are no cars around me and it shouldn't have done this. This has been happening for some time and only happens haphazardly meaning I can't always have the dealer identify or diagnose the issue. Then when I brought it to the dealer, they told me it was because of a power liftgate module error. Which was not true and didn't solve the issue.

We took our vehicle in to Honda to repair the mirror recall and they were unable to repair it because they did not order the parts necessary to complete the work. All this despite us making an apt well in advance so they could be prepared. Upon picking up our vehicle, we were told “not to worry about it because if the mirrors haven’t fallen off by now, they probably won’t.”

I own a 2020 Honda Odyssey and I am currently having a safety issue with the power tailgate. Upon inspection by my Honda dealership, my vehicle requires a new power tailgate control unit and floor harness and my roof rail and clips need to be re-sealed and replaced. It was discovered that due to the break in seal the connectors corroded due to a water leak.In April of 2026 I received multiple warning messages on my dashboard. The first was Power tailgate problem and the second was keyless remote problem. At first I noticed my car continuously beeping while driving along with the warning on my dashboard. I attempted to turn the vehicle off to see if it would reset, but it did not. I attempted to open and close my tailgate. I could only open my tailgate with the push button on my dashboard. I had to manually close my tailgate due to my buttons on my car and my key fab failing to work. Next while driving, I could hear the locking mechanism on my tailgate continuously locking and unlocking. Of course this particularly concerned me because I have 3 young children and their safety as well as mine was in danger. It was unclear if my tailgate was going to open while driving. Such an action could potentially cause a serious threat or harm to myself, my family or other vehicles on the road.

Car leaks. Cargo Bay fills with water. Possible mold issues. I am told this leaking causes damage to the control module for the tailgate. Our tailgate will close on us and has almost closed on our children. We have to be very careful when the children are around the tailgate because it will begin to close without warning.

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.

The Infotainment system continually goes blank, while driving leaving the backup camera disabled and without navigation. I returned the van a week after purchase and did not get it back for a month. Despite the recall was never completed. It has been back to the dealer 6 times for the same issue with no improvement. Currently the problem still exist and the dealer WILL NOT HONOR the uncompleted RECALL ISSUE. The dealer insists the recall was completed yet the original issue was never resolved and is saying I will need to cover all costs.

Honda Odyssey Idle Stop system failure Vehicle: 2020 Honda Odyssey (Elite) Incident description: While driving, the vehicle's "Idle Stop" system engaged as I came to a complete stop at [e.g., a traffic light, intersection, stop sign]. The engine shut off as designed, but failed to restart automatically when I released the brake pedal. This left my vehicle stalled and disabled in the middle of [e.g., an intersection, a lane of traffic] with no forward power. I was scared as there were lots of cars behind me in the intersection. This has happened over a dozen times. Safety risk: This failure created an immediate and dangerous safety hazard. My vehicle was a risk for being rear-ended by traffic from behind, and my family was stranded in a vulnerable position. The vehicle was unable to move out of harm's way, and I had to put the vehicle in park and manually restart the engine. This is unacceptable for a system designed to work seamlessly and automatically. Additional information: This is not an isolated incident. The auto start-stop failure has occurred multiple times since March 2025. The system failure has put me and my passengers in a position of significant risk multiple times. Failed component: The vehicle's "Auto Idle Stop" (AIS) system, which failed to restart the engine after it was automatically shut off. Resolution: An immediate and permanent recall is necessary to address this dangerous defect. Existing service bulletins have not corrected the problem. I urge the NHTSA to require Honda to provide an effective, long-term solution to ensure the safety of Odyssey owners.

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.

For the last few days I turn on my car and get alert lights that I have problems with: the ACC, LKAS, collision mitigation, road departure mitigation systems and auto high beams. From online Honda forums I can see that many people have had these problems and it’s likely due to needing to have the windshield camera replaced. This is a 2020 model but I bought it new in 2021, so it is less than 5 years old and I’ve got 94k miles on it. Honda markets itself on its safety features, but nearly all of my safety features are not operating properly less than 5 years from the date of purchase, it’s a widespread issue, and Honda still has not issued a recall.

My can intermittently fails to start after the auto idle start system has engaged. I am stopped at a light on a busy road. When the light turns the car tries to start but fails. Some times it is able to start but I get warnings that multiple systems had an issue or at disabled. Other times it fails to start completely and I have to cycle the power off and open my driver door before I can start the car. This has been happening for more than a year and the battery has already been replaced.

My Vehicle was at the dealer for service in March of 2025. At that time they performed RECALL 23-008 although the vehicle did not have issues with the idle stop system. Since some time in June, at multiple occasions, the vehicle shifted to Park on its own when restarting from idle stop. Last night, the vehicle fully shut off and lost all electrical power when restarting from idle stop leaving me stranded in the dark at a busy intersection without the ability to turn on my hazard lights. The vehicle repowered after a few minutes. When the system restarted, the info-tainment system activated the anti theft software which happens during full power loss.

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.

1) Infotainment system crackles, pops, and shuts off frequently. Will not come on sometimes until 5 minutes into the drive, meaning we cannot use our rearview backup camera. This was recalled in other models but not our specific VIN. 2) “Shutter grill problem; power reduced” comes on randomly even when just idling. 3) Sliding doors will bounce shut or not open all of a sudden! Both doors affected similarly. Turning off the power doors does not solve the issue, so we lose access to one side. There was a recall on sliding doors for other models but not our VIN. We are taking it into the dealer to investigate but this is a safety issue.

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.

Several times over the last 18-24 months my van has 'stalled' after the auto engine start/stop feature restarts my car. This has mostly happened while at stop lights/signs, or idle. However, it has happened twice while driving, my car will just die and slow dramatically. I have been able to restart by pushing the start/engine button. There has been two times where restarting (while idle) has not worked. Most recently it happened while at a stop light. when the light turned green I went to accelerate and the van would not move, all the dash lit up, and there was no power to the engine. It took several minutes to get the van restarted, holding up traffic and causing me panic and fear that I could be hit.
