| Oct 2023 | UNKNOWN OR OTHER | Occasionaly car will not start of up after Idle Stop engages. Collision warning flashes then leaves us stranded in intersection. Very Danagerous. | Crash: No Fire: No | Unknown |
| Oct 2023 | ELECTRICAL SYSTEM,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Sep 2023 | ELECTRICAL SYSTEM,STRUCTURE,UNKNOWN OR OTHER | 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. | Crash: No Fire: No Injuries: 1 | Unknown |
| Sep 2023 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | ELECTRICAL SYSTEM,BACK OVER PREVENTION | The contact owns a 2020 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 23V431000 (Back Over Prevention). The contact stated that on several occasions while driving at various speeds, there was a static sound from from the radio. The vehicle was not diagnosed. The manufacturer was not notified of the failure. The failure mileage was approximately 20,000. | Crash: No Fire: No | 20,000 |
| Aug 2023 | ENGINE | When the car engages the Idle Stop feature and shuts the engine off, the engine does not restart immediately once the brake is released. This has happened multiple times but the last time a message appeared that said to change gears and restart the car. In the meantime the vehicle was in traffic and stopped for over a minute before it could be restarted. This put us in danger of a rear end collision as other cars were wanting to go. | Crash: No Fire: No | Unknown |
| Aug 2023 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | 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 | Crash: No Fire: No | Unknown |
| Aug 2023 | UNKNOWN OR OTHER | 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? | Crash: No Fire: No | Unknown |
| Aug 2023 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | This event happens intermittently, and has occurred approximately 4 times. When the issue occurs it happens as follows: 1. Vehicle comes to a complete stop, and driver's foot has depressed brake pedal 2. Vehicle automatic start/stop feature turns off engine. 3. Driver lifts foot off pedal, begins to apply pressure to gas pedal. 4. Vehicle automatically re-starts engine 5. Vehicle starts to move forward, and then lurches - it feels like the brakes are being applied by the vehicle independently from the driver's action. 6. Alerts start appearing on the dashboard - a message that the Forward Collision Warning System has been disabled and the "BRAKE" light starts flashing for 30 seconds to a minute afterwards. 7. Vehicle then starts to move forward without issue, Collision System message goes away, but BRAKE light on instrument cluster continues to flash for a period of time. This issue presents a safety risk as the vehicle does not respond to driver's input as expected when this issue occurs, appears to brake on its own. Interferes with a driver's ability to move through an intersection after stoping. I have taken the vehicle to a Honda dealership (Penske Honda, Indianapolis Indiana) and they were unable to replicate the issue and did not find any stored error codes in the vehicle comptuer. | Crash: No Fire: No | Unknown |
| Aug 2023 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | 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. | Crash: No Fire: No | Unknown |

The failure mileage was approximately 14,000. Parts distribution disconnect. | Crash: No Fire: No | 14,000 |
| Aug 2023 | ELECTRICAL SYSTEM,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | UNKNOWN OR OTHER | 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." | Crash: No Fire: No | Unknown |
| Aug 2023 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Honda 36160-THR-A81 Camera Monocular for 2019 Honda Odyssey 36160THRA81 Honda Sensing Camera Monocular system failed giving ACC- Adaptive Cruise Control Problem, LKAS - Lane Keep Asset Problem, Collision Mitigation Problem, Road Departure Mitigation System Problem, Auto High-Beam Problem, Brake System light on. | Crash: No Fire: No | Unknown |
| Aug 2023 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Front windshield camera, controls adaptive cruise control, lane keep assist, lane departure mitigation, front collision mitigation, auto high beam, all the lights came on and all the features stopped working. We were 1500 miles from home when this happened had it repaired at a dealership $1300. I called Honda corporate and after 2 days a customer service representative called me back. He told me the vehicle was 2500 miles out of warranty and it's a car and cars are going to break down. That I should drive it back home and have the dealership repair it and they might be able to help with some kind of reimbursement. I did not want to drive it that far without all the systems functioning so he said well that's on me. | Crash: No Fire: No | Unknown |
| Jul 2023 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Jul 2023 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The following errors suddenly appeared one-at-a-time, causing all the advanced driver assistance capabilities to stop working, including regular cruise control: * ACC - Adaptive Cruise Control Problem * LKAS - Lane Keeping Assist Problem * Collision Mitigation System Problem * Road Departure Mitigation System Problem * Auto High-Beam Problem * Brake System light also appeared. Battery replacement did not fix issue. Errors usually appear within about 30-60 seconds of turning the car on, but errors occasionally go in and out intermittently. Lights come on with a distracting beep one-at-a-time, causing major distractions while driving and suddenly disabling any active cruise and/or LKAS features while driving in traffic. Dealer stated the windshield mounted LKAS camera needs to be replaced for $1592 + tax. Safety features should not be flaky, and customers should not bear the cost of repairing safety equipment such as this. This should be strongly considered for a recall. | Crash: No Fire: No | Unknown |
| Jul 2023 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Jun 2023 | ELECTRICAL SYSTEM,ENGINE | Vehicle’s “Engine Idle Stop” feature malfunctions unless it is turned off manually. This is an energy conservation feature which turns off the engine when stopped. However, when lifting the brake, the engine does not turn back on at times, sometimes fully stalling the vehicle. At times, numerous lights have come onto the dashboard after this happens. At other times, the vehicle has completely turned off, leaving the safety of the driver and passengers at risk, particularly at stop lights, stop signs, and when in stop and go traffic. I’m continually worried someone is going to rear-end us when they see our brake light go off at an intersection. Vehicle has been brought to Honda dealership who stated they did not know the cause and replaced the battery. Problem was not solved and continues to happen. | Crash: No Fire: No | Unknown |

We were able to get the vehicle in park and come to a stop. I turned it off and back on. No other messages appeared. The vehicle drove as expected and brakes worked. | Crash: No Fire: No | Unknown |

| May 2023 | FUEL/PROPULSION SYSTEM | The idle stop caused my car to turn off on the highway while I was stopped in traffic. Unfortunately, I was the last car in the line on the highway and the truck coming behind me was coming at a rapid rate of speed. Thankfully, the same issue had happened to my son the week before and he was able to tell me that putting the car in park and turning it off and back on would fix the issue. There is a service bulletin 21-013 related to this issue but not a recall. This is a safety issue that needs to be addressed. | Crash: No Fire: No | Unknown |
