| Jan 2024 | POWER TRAIN,ENGINE | I have a concerning noise from my car's engine that I’ve already brought in for diagnosis. Knocking/ticking/rattling noise on stand-still acceleration at relatively low speeds/under light load. Does not duplicate when revving in park, only under light load. Sound present with HVAC on or off. Does not make noise when cold or after long trips. Honda seems to be aware of this issue and has remedied it through work involving the crankshaft bearings and possibly other components as it relates to their service bulletin 23-097. The problem is that my vehicle falls outside of the stated range of production years as mine is a 2020 model year, but the likelihood seems quite high that the engine in my vehicle is suffering from this exact problem. The service department refuses to help me and the corporate line I've contacted through email me simply refers me to the service department. I just spent $38,000 on this vehicle with 30,000 miles and I have no other recourse at this point to remedy this. | Crash: No Fire: No | Unknown |

| Dec 2023 | UNKNOWN OR OTHER,FUEL/PROPULSION SYSTEM | The car stalled when stopped at a red traffic light. This happened on 2 occasions, 11-3-23 and 12-9-23. The second time other cars behind us had to go around us while we tried to restart the car which put them at risk of being hit by cars in the other lanes. There was no warning. I took the car in for regular maintenance a few days ago during which the dealership did a multi point inspection but did not discuss this issue. Yesterday I heard about the fuel pump recall and think this might be the same issue. I called the dealership today but they said our car is not under the recall. Our car is available for inspection upon request. | Crash: No Fire: No | Unknown |
| Nov 2023 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | Idle stop caused engine to stall 3 separate times leaving me stranded in busy intersections making it difficult to restart vehicle and move safely out of the way. Initial start up checks come on, asked to put car in park, step on brake to restart car, car won’t restart. Once happened at night and shut off all my lights for 30 seconds making me not visible for cars coming up to me. | Crash: No Fire: No | Unknown |
| Nov 2023 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The entire ADAS system has begun loosing sensing capabilities for a time period but start working again later. It comes and goes regularly at this point. This inconsistency could cause and accident. There are system problem warning lights on the dash when the system is down. The car is too new for this issue. The dealer reports that the front camera is the issue but I would think it has more to do with the wiring possibly shorting out. | Crash: No Fire: No | Unknown |
| Nov 2023 | ENGINE | While stopped in preparation to make a left turn across traffic on a 4 lane road, our 2020 Honda Odyssey engine stalled- the engine idle stop function did not restart the engine as designed. We had to restart our car, but the car did not immediately restart, it took us 2-3 attempts. There was no prior warning or indication there was a problem. We could have easily been hit by another car, injuring my wife and children. Our system is available for inspection, we have not had it inspected yet. | Crash: No Fire: No | Unknown |
| Nov 2023 | POWER TRAIN | Driving in traffic, switched lanes into a turn lane and came to a stop. The van put itself in park and wouldn't do anything for 5 minutes...the van kept running. It couldn't be shifted out of park, it couldn't be turned off. After approximately 5 minutes was able to put it back in drive and drive away. | Crash: No Fire: No | Unknown |
| Nov 2023 | ENGINE | My vehicle has the engine idle option and shuts the engine off when idle in traffic or at traffic lights, etc. There have been incidents where the engine doesn't just shut off but it powers off the entire car and doesn't want to turn back on. My battery is fine because i just had service done on it and they tested the battery and its 100% fine. This issue is not a battery issue for my car. I literally had PTSD when the car shut off though because it happened at a location on the roadway where i had previously been rear ended in another vehicle and after my car shut off this time - my anxiety was very high that day and i was literally shaking. I was scared not knowing what was wrong with my car. | Crash: No Fire: No | Unknown |
| Nov 2023 | VISIBILITY/WIPER | I had a Recall on my 2020 Honda Odyssey Vin # [XXX] for NHTSA Recall # 23V-431. The recall was for rear camera failure. The Fix was to replace MOST cable harness. In Early October 2023 my rear view camera did fail and no longer conformed to Federal Motor Vehicle Safety Standard No 111, “Rear Visibility” I took my Honda Odyssey to Serra Brighton Honda for repair , Serra Brighton Honda replaced the cable and it did not fix the problem. I was told it was the camera which was not part of the recall and was charged $302.42 for replacement of the camera, Invoice # [XXX]. It only seems logical to me that if “Rear Visibility” is a Federal Motor Vehicle Safety Standard , the camera should have been included as part of the fix. It could have been possible that the cable shorted out and damaged the camera’s electronics. My Honda only has 21,500 miles and is always stored in a garage and has never been in an accident.

| Nov 2023 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | All advanced driver assistance systems have stopped working while driving. This has also caused brake and transmission errors to show. | Crash: No Fire: No | Unknown |
| Nov 2023 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | LKAS, Adaptive cruise control, forward collision warning, automatic emergency braking, lane departure warning all malfunctioned. Dealer inspected and determined it is an overheated camera that controls all the mentioned safety functions. This happened while driving on highway and has never worked again. I did confirm with the dealer this is the 3 instance they have seen of this in the past 3 months. | Crash: No Fire: No | Unknown |
| Oct 2023 | POWER TRAIN | My wife was driving our honda odyssey on a state highway and it began lurching and drastically reduced speed while in 65 mph traffic. The vehicle almost created a large accident as it uncontrollably and suddenly reduced gears and instantly slowed well below the rate of travel of the vehicles on the road. She managed to pull over on the side of the road but was unable to move the vehicle . There was never a check engine indicator or any other warning signs prior to this happening. The vehicle was towed to the local honda dealership in Scranton PA. Today the service center there stated that the transmission fluid was charred and burnt up gears in the transmission. This is a huge safety concern as there was no warning signs of the issue until the vehicle rapidly and suddenly shifted down gears and slowed to almost a complete stop along the highway. The vehicle is only 3 years old and is 900 miles over the powertrain warranty. Has there been a check engine light or any indicator we could have had the problem addressed before it became catastrophic and put my families lives in jeopardy. The vehicle has been regularly maintained | Crash: No Fire: No | Unknown |
| Oct 2023 | VISIBILITY | The contact owns a 2020 Honda Odyssey. The contact stated that on several occasions while driving at various speeds during rainy weather, he attempted to defrost the windows; however, the HVAC failed to operate as designed with warm air coming from the HVAC system. As a result, the windows failed to defrost as needed, making it difficult to see the roadway. The vehicle was taken to the dealer where it was diagnosed and determined that the blower motor had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was notified of the failure and advised the contact to take the vehicle back to the dealer for assistance. The failure mileage was approximately 32,400. | Crash: No Fire: No | 32,400 |
| 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 |
