The rear lift gate fails to hold in the up position, the powered lift gate subsequently and randomly closes on its own without any driver intervention. The powered lift gate closed on me while I was retrieving groceries, almost crushing me had I not forced it back up by force. This has happened multiple times and could be lethal to a child or even an adult. The vehicle only has 39, xxx miles and has been used lightly as a family vehicle. The vehicle is available for inspection by NHTSA officials. Additionally, I have seen other vehicles with the same problem video taped on YouTube. Such links can be provided to investigators. Honda should recall these vehicles and disable the automatic closing of the lift gate that is occurring without any driver intervention. It is beyond reasonable to assume this fault can be lethal or cause serious bodily injury.

The contact owns a 2020 Honda Odyssey. The contact stated that upon starting the vehicle, the instrument panel failed to display any information and the rear-view camera failed to display an image. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the gauge control unit. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 20V439000 (Back Over Prevention, Electrical System), but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was unknown.

Three times now our 2020 Honda Odyssey's entire instrument and infotainment system has gone out - both screens at the same time just don't turn on. Which means we have no MPH gauge or back up camera. It is extremely unsafe to drive without a speedometer and we paid extra to get a van with a backup camera and now we don't even have that. We've taken it to Honda and are getting charged to replace the entire system, even though it is clearly a connection issue (since it turns back on by itself). On the exact same vehicle, the entire right rear shock is completely blown out and needs replaced. Both happened with no warning. Honda is not helping on a vehicle that only has 40,000 miles on it.

Power tailgate module exposed to water due to manufacturer defect in sealing above module. causing various electrical systems to fail including safety features. I do have the damaged module. Tailgate opened and wouldn-??t close, when car in motion. Unable to use vehicle, the amount of electric items, due to fear brakes or transmission would fail while driving minivan full of young children Vehicle had warning light shortly after heavy rain. Was intermittent.

Auto idle stop. When the auto idle stop is on, when the vehicle is stopped at a light or due to traffic the vehicle while in drive will completely turn off. Unable to hit the accelerator to move as designed. We have to restart the vehicle and sometimes it takes multiple restarts. Extremely unsafe since we are unable to keep up with traffic. It has happened multiple times without warning. We have to make sure make a point to keep the auto idle engine turned off, but when you turn the car on it is automatically turned on. Called Honda, no recalls on this issue.

We bought a used 2020 Honda Odyssey, and a few months after buying this vehicle, the infotainment screen blanked out and the vehicle information screen also blinked out. This occurred at the same time with no warning whatsoever. I just turned on the car, and none of the screens came on. These screens are the ones that show the mph, our mileage, cruise control, etc, and also the screen that shows the back up camera, in car calling, back up alert system. None of that works anymore. We made an appointment to take it to a Honda dealership and a few days later it flickered back on and so we did not keep the appointment. Just a month and a half later, it happened again and this time it has not come back on for over a month. We took it to the dealership and were charged $200 for them to tell us it was something wrong with the Honda computer system and the whole thing would need replaced and we would be charged $1800. This is on a barely 4-year-old vehicle & we did not have the money to replace a defective system. So we have been driving without a mph display. We put our phones up on the dashboard and try a GPS MPH app, but it is wildly inaccurate, and it is a major safety concern because we have no idea what speed we-??re going and we have to guess. This is a car with low mileage and barely 4 years old!! We paid a lot of money for the back up camera, in car calling, and extra features like that specifically for the safety of those features. And now we-??re being told that basically they can-??t find the problem and we have to pay $1800 for those rather high-priority safety features like knowing how fast you-??re going. I also have a newly licensed teenage driver and another who will get her temps in 2 months. I can-??t even let them drive our vehicle because they certainly don-??t have the experience necessary to drive with no speedometer. We live in a state that doesn-??t allow handling a phone in any way. This vehicle helped me comply with that & now I must use a phone to show my mph

When trying to close Rear sliding doors it just beeps once it gets half way closed then it gos back open and it won-??t close unless you turn off automatic mode to manual and you have to physically Very hard to close them and they are very hard to open like very hard to open and close so if you don-??t have the strength and it happens to you your screwed or stranded with your little kids and specially if you don-??t live in a great neighborhood that can be very scary and from what I-??ve researched online that on the Honda odyssey it is a very common issue and Honda just wants you to spend 1500$ to fix it and from what I-??ve seen it-??s either the cable or the motor or the rollers apparently it-??s very common for the motor and the cables to die and break and if you call the Honda dealer, they know exactly what the issue is that-??s how common it is. I definitely believe it should be recall. And I believe in my opinion, that-??s a major safety issue

The heads up unit, navigation and audio system completely shut down after Network connection lost message. This started happening after recall of a cable, before it was fine, same cable was replaced under warranty a year ago. The problem is reproducible, simply driving vehicle and hitting a bump on passenger/right side cases the system to malfunction, disconnect audio, and eventually whole system shutdown and restart. I will take this back to the dealership but electronics in Honda Odyssey has been unreliable and feels like a safety risk.

There was a water leak on the interior rear driver side, causing the tailgate control module (TCM) to fail part # 74970-THR-A12 The tailgate trunk or 5th door is not working, will not open, will not activate. I took my 2020 honda odyssey my local dealership but no help. Many vans from Honda, years 2018-2021 are having this very same issue. Please help Me resolved this matter. Honda should have a recall on this and replace at no charge.

Vehicle driver side sliding door has issues closing. Mentioned to dealer, but dealer dismisses it as possibly from water residue after car washes. Door needs to be manually closed with pressure to latch. Vehicle has lost all electrical function while in Economy mode while in idle mode while at red lights and also while parked with accessories running. Vehicle batter life was verified and in excellent condition at battery replacement shop.

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.

At a stop light the engine idle shutoff feature shut off the engine. Then a few moments later the entire vehicle shut off. I could not turn the vehicle back on after trying several times to do so. After about five attempts the vehicle turned back on in park gear. During this time the light turned green and the vehicle would not turn on, cars behind began honking. This has happened a few times since owning the vehicle. I was dead in the middle of a busy intersection. I have asked the dealer to look at the electrical system as there have been several anomalies but it checks out fine. I replaced the battery thinking that might be the problem but did not work. I believe it is the same problem as PE22005

On at least 5 occasions the car has not restarted after going into auto idle while stopped. Normally after pressing the brake pedal all the way down while stopped, the engine will shut off and then restart after releasing pressure from the brake pedal. When it doesn't restart, all the lights on the dashboard come on and you can't do anything. It won't restart if your press the start button and you can't shift it to neutral to push it out of the road. Eventually it will restart by pressing the start button. I have not had this problem if I turn off the auto idle, however you have to manually turn off the auto idle every time you restart the car.

1)The back hatch will randomly close. The first time it happened I didn-??t know what was going on and it hit me in the head. Today my kids were there and it almost hit them but I pushed them out of the way because I knew what was happening as it makes a certain noise first. 2)It stalls out randomly at red lights. 3) the doors won-??t open or close at times. 4) the dvd player gets so hot it almost burns you and the dvd player won-??t work. When I contact the dealer they say they can-??t do anything since it happens randomly and it if doesn-??t happen when it-??s at the dealership they don-??t know what to do so they don-??t even make an appointment. Two years ago we complained that the door didn-??t have a sensor because it shut my two year olds hand in the door. Honda acted like we were crazy. Then it became a recall and they -??fixed-?? them. But now they won-??t open or close.
