Power Train Problems of Honda Odyssey - part 1

The contact owns a 2025 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The failure had occurred while driving from a stoplight, while the auto idle system was enabled. There was no warning light illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The dealer was made aware of the failure. The contact was advised that a diagnostic test was needed to determine the cause of the failure. The failure had occurred three times; however, the failure had not reoccurred after turning off the vehicle. The dealer informed the contact that the failure might not be duplicated. The manufacturer was not made aware of the failure. The failure mileage was approximately 12,549.

Upon pressing the accelerator from a complete stop, the vehicle does not respond right away. The main incident was when traveling around 50 miles per hour on a highway, the van shifted into neutral on its own and the accelerator would not respond. An error message of transmission failure showed on the dash briefly. The van had to coast through traffic an eventually push off the road.

Vehicle lags in acceleration from a slow rolling start, at random times. There is a clear 1-2 second lag in the acceleration, then a sudden harsh shift into gear. Mostly happens during turns, and if traffic is present, may cause an accident. Also when traveling at low speeds 20-35 mph, there is a transmission jutter. Have spoken with service reps at dealerships and they claim to have no knowledge of these transmission issues.

Transmission stops producing power and has delayed acceleration. Almost caused an accident and possibly fatalities.

Improper seal on the seam (?) above let water leak into my power tailgate control module. It caused all the dash lights to sporadically rapidly flash, told me I have a transmission problem and my blind spot warning didn’t work right. Pulled out the tailgate module to find water in the module with a failed circuit board. Also wires leading into the module were wet.

After I received a software update for my 2018 Honda Odyssey elite the car has been stalling when idle. It is very dangerous because I will be at a stop light in drive, and the vehicle will shut off with no power. Cars will be behind me or no cars, and I have almost been rear ended. I did not have this problem until I received the new software update. It keeps occurring more and more often.

I am submitting this complaint to report a serious and recurring safety issue with my Honda Odyssey involving the camera system. Multiple warning messages and fault codes appeared on the dashboard simultaneously, including: -collision mitigation system problem -adaptive cruise control problem -lane keep assist problem -auto high beam problem these systems are all disabled. This failure occurred without warning and immediately compromised several critical driver-assistance and safety features. We have serviced at Honda dealerships and they said the only fix is a new $1500 camera (but the camera still works). Despite this, no recall has been issued. We have owned Honda vehicles for decades and never had these type of issues. A recall needs to be announced and owners allowed a fix at no charge. The transmission warning lights are also coming on intermittently and we paid to have Honda diagnose. The transmission is fine they said. Please help.

While driving pressing on the gas pedal I got a minute of no acceleration, it felt like the van stopped on me, and then I start pressing on the gas pedal harder but nothing happens and then it shoots forward like a jet, this happened a few times, very dangerous, could have got hit from behind from oncoming traffic behind me since the van just slowed down so much, then shooting forward was also scary. I did take it to a mechanic in the past and they couldnt figiure out what was wrong. The transmission light went on last week and the van didnt drive, I had to tow it to two different mechanics, both letting me know that I had to replace the transmission on my van, this is only a 2019 and only has 74,000 miles on it, this shouldnt happen.

Hello - on [xxx], while travelling to visit family for the christmas holiday, a warning about a transmission system error came on. We pulled over, check fluids, looked the vehicle over, added approved coolant which appeared a little low. When we started our van, all the lights were off, and we were able to reach our destination without incident. On [xxx], all fluids were checked prior to leaving to return home and we began our journey home. About 20 minutes out from our destination, our transmission warning light came on once again. We were able to make it home. We contacted the dealership and dropped it off immediately on Monday morning only to find out that the transmission needed to be completely replaced. We obtained a second opinion with a local transmission shop who then proceeded to tell us that this was a known issue with this year of Honda transmissions and that there are some well documented issues with this particular transmission and that this was unfortunately not the first case they had seen. We purchased our 2019 Honda Odyssey from o'daniel Honda in omaha, nebraska through the costco auto program in August 2019. We have regularly maintenance done on this vehicle as recommended at another local dealership closer to our home. At present time, my [xxx] Honda Odyssey with barely 100,000 miles on it now sits in a transmission shop awaiting a full transmission replacement. We bought this vehicle in the security and knowledge that it would be a solid, reliable vehicle for our growing family at the time with the reputation for exceeding 250,000 miles when properly maintained. For this transmission issue to be so well documented and known and for Honda to completely turn a blind eye to this and not stand behind their workmanship is absolutely appalling. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The transmission in my 2019 Honda Odyssey failed prematurely at approximately 102,800 miles, requiring a full transmission repair/replacement. Prior to failure, the vehicle exhibited known warning symptoms including harsh and erratic shifting, hesitation, delayed engagement, and loss of smooth acceleration. These symptoms progressively worsened and ultimately resulted in unsafe drivability. This failure is consistent with a well-documented pattern of transmission defects affecting 2018–2019 Honda Odyssey models. Numerous owners have reported similar issues through NHTSA complaints and Honda service channels. A transmission failure at this mileage is not consistent with reasonable consumer expectations for a modern vehicle and presents a safety concern due to unpredictable shifting behavior, hesitation during acceleration, and loss of drivability. These issues increase the risk of collision, particularly when merging, accelerating from stops, or driving in traffic. Honda has declined assistance solely on the basis that the vehicle is outside the powertrain warranty, despite the failure aligning with known defect patterns rather than normal wear and tear. I am submitting this complaint to document a recurring defect and request further investigation into premature transmission failures in this model year. After receiving a replacement transmission in my 2019 Honda Odyssey, the vehicle continues to experience the same failure symptoms: harsh shifting, delayed engagement, and intermittent slipping. These ongoing issues indicate that the replacement transmission did not fully correct the underlying defect, which is consistent with other complaints submitted to NHTSA regarding 2018–2019 Odyssey models. I am requesting that NHTSA investigate this recurring defect and track the persistent issues associated with replacement transmissions in this model year.

Vehicle was driving normally down the highway then proceeded to shutdown without warning. Suddenly all of the trouble lights appeared indicatinging engine, transmission, hill assist etc cut on without warning. The van would not drive above 55 mph when turned back on.

The car sporadically does not shift from 1st 2 second and then abruptly shuts cause a loud jerk of engine and car. It is startling and scary when it happens. I’m afraid the car will break down while in the road. Every time we take the car to dealership they “cannot replicate” issue therefore there is nothing to fix on an issue that is all over the internet with Honda vans and suvs.

My vehicle repeatedly and unexpectedly shifts into neutral while in drive, causing a sudden loss of power in traffic. This has happened multiple times without any input from me and has nearly caused a crash.

The vehicle experienced a sudden internal transmission failure (power train). While driving, the vehicle began making grinding noises during acceleration and lost propulsion. The vehicle then displayed multiple warning indicators, including a transmission warning and a blinking electric parking brake indicator. After stopping, the vehicle would not engage drive and became inoperable, requiring towing. The transmission remains available for inspection at the dealership. This failure created a safety risk due to loss of propulsion and inability to move the vehicle under its own power, including the risk of being stranded in traffic or unable to safely clear a roadway. The problem was confirmed by an authorized Honda dealership, which diagnosed an internal transmission failure and recommended full transmission replacement. No prior transmission repairs had been performed by outside shops. The vehicle has been inspected by an authorized Honda dealership. The manufacturer has not physically inspected the vehicle beyond dealership diagnosis. Warning symptoms included intermittent grinding during acceleration and loss of power shortly before complete failure. Warning messages and indicators appeared at the time of failure.

The transmission failed at 108k miles. Honda is charging 10000usd for repair. They want to replace the 9 speed transmission. This transmission is notorious for failure and Honda hasn’t issued a recall yet.

Dear NHTSA, I am submitting a safety complaint regarding my 2025 Honda Odyssey, which has been diagnosed with a transmission failure requiring full replacement due to faulty internal seals. The vehicle is less than one year old, and this type of premature failure raises serious safety concerns. I first became aware that something might be wrong during a routine oil change on November 11, when technicians noticed signs that the transmission might be leaking or malfunctioning. I continued to monitor the vehicle, and on November 28, I was informed that the entire transmission must be replaced due to faulty seals inside the transmission assembly. A critical component like the transmission should not fail this early in the life of the vehicle, and a structural defect such as faulty seals may indicate a manufacturing issue that could affect other vehicles of the same model and year. Information from the dealership: sheehy Honda of alexandria diagnosed transmission failure caused by faulty seals recommended repair: complete transmission replacement explanation: premature failure of internal transmission seals leading to fluid loss and unsafe operation repairs completed so far: diagnostic inspections confirming failure this vehicle is used to transport children, and a sudden transmission failure presents a significant safety risk. For a new vehicle to require a full transmission replacement within its first year of use is highly concerning. I am requesting that NHTSA review this issue to determine whether other 2025 Honda Odyssey vehicles may also be experiencing similar premature transmission failures. Thank you for your attention to this matter. I can provide repair documentation, inspection notes, photos, or any additional information upon request. Sincerely, allison epps 334-464-0233 alijepps@gmail. Com vehicle: 2025 Honda Odyssey.

-torque convertor/transmission. We do currently have it and it could be inspected. -a sudden transmission failure could pose a safety risk to us and others. -yes, see story below. Technician drove and did report feeling the shuddering. -yes, by Honda and now a third party mechanic. -no lights. We received a recall/extension warranty for the torque converter/transmission. My van is currently having shuddering issues. When we took it to milton martin Honda in gainesville, GA, they reported the issue is present, but not at a certain "threshold" for them to be required to fix it. They then proceeded to charge me $175 for diagnostics because the issue did not reach said "threshold. " they then proceeded to tell me that a torque convertor will cost me $5200 and that the reason it is so expensive is because they just raised their prices on torque convertors. Definitely appears that they are weaseling out of fixing these recall/warranty extensions and then up-charging when people do have to pay cash for the vehicle to get fixed. Also I have researched and torque convertors with labor are not that expensive and thus things seems a bit nefarious. Currently we are getting a third party mechanic involved to assess the vehicle further.

I came to a stop at a stop sign. Then "auto off" shut off the engine. Next, the vehicle went into park. A message came on screen telling me to press the brake and the start button. Doing so had no effect. Cars behind me started honking. After repeatedly stabbing the start button and opening and closing my driver's door, the vehicle eventually rebooted, and the engine started as normal. This caused a dangerous situation where other cars went into opposing traffic to get around me.

I have had multiple issues with the radio (16000 miles). After many personal videos dealership was able to fix one of this issues with a new part (22000 miles). I was informed the other issues I was having with the radio was due to my battery not staying fully charged. I was also having issues with the van not starting right away, which made me feel I could get stranded. It took many attempts to get the van to start. The van also wouldn't let me reverse one time, with a message telling me to place van in park. Another issue is the van is very slow to restart from auto idle shut off. The transmission is slow to change gears in lower gears and the van jerks a little bit. Next my rotors were warped. I was informed by the dealership that there was nothing wrong with my transmission and the auto idle down was working properly. No one could explain the rotors being warped. They reshaped my rotors and replaced the battery and told me they hoped that fixed the problem. Well indeed it did not fix the problem. As of 12/27/25 the van completely shut off at a stop sign and again on 12/28/25. The issue is only getting worse (24,000 miles) and now I am scared to death that the van will stop while I am driving. The dealership has been contacted and I am waiting on a call back for a loaner car. I was in traffic and was extremely worried about my safety, as well, the safety of others around me and with me. ( side note I returned the van to another dealership soon after the first dealership performed work on the van, when I heard a metal on metal sound and what sounded like a bolt rolling around in my back brakes. They did not find anything wrong but were also puzzled by the rotors already being warped. I was afraid to make the trip to the orig dealership). I have recently gotten a video of the brakes scraping again. This van is causing a lot of safety issues for my family.

The idle stop system is malfunctioning. I had it inspected once previously and now trying to get it inspected again for the same occurring issue. The dealership continues to tell me to turn off the idle stop feature on the vehicle. My safety was put at risk because of the vehicle stalling and not kicking back on while being stopped at a redlight on a busy 4 lane highway multiple times now. The first time, I was by myself. The second time, my 8-month-old was in the vehicle with me. This causes a lot of panic as there are impatient drivers around me since I am unable to move my vehicle. I fear that this could happen on a freeway if there was construction, an accident or even while trying to turn in an intersection and getting hit because I can’t move my vehicle and often have my two small children with me. The first time the idle stop stalled, it occurred twice in a week. The first time was rather quick, and the engine kicked over quickly so I did not think anything more of it. The second time which happened a few days later (9/17/25), took about 5 minutes to get the engine going again and moving on the road (4 lane highway). I took it back to my local Honda dealership where they performed a diagnostic test and discovered the battery had dipped down to 7. 22v when trying to restart, the battery failed the battery test and ended up being replaced with a new battery. The idle stop issue has now happened for a third time (10/21/25), with the same issues occurring and I am waiting to be able to get back into Honda. The vehicle has only been looked at by my local Honda dealership. There were no warning lamps, messages, or other notifications prior to the failure. I received a warning on the dashboard after the events occurred on how to start the vehicle. This is very disappointing as a new Honda owner. My husband and I decided on Honda over other car companies due to their reliability and this has now become a constant worry.

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the vehicle suddenly shifted into neutral as indicated by the gear shift indicator light. The contact was able to coast to the shoulder of the roadway, where the failure persisted, and the vehicle was unable to shift into drive. The adaptive cruise control, lane keep assist, collision mitigation system, road departure system, and transmission fault detected messages were displayed. The vehicle was towed to an independent mechanic, who diagnosed a failure with the transmission control unit. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA campaign number: 19v299000 (power train, electrical system), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 133,000.

2018 Honda Odyssey (10-speed automatic transmission) what happened: the vehicle is experiencing intermittent loss of reverse and delayed gear engagement from a stop. When shifting into reverse or drive, the engine revs but the vehicle does not immediately move, then jerks into gear. The issue is worse when cold. Warning lights / codes: check engine light on. Honda dealer retrieved diagnostic trouble code p0763 – shift solenoid c electrical. The code returned as a hard code after being cleared. Safety risk: the vehicle hesitates or fails to move when shifting into reverse or from a stop, creating a safety risk in traffic, parking situations, and when backing up. Current status: diagnosed by Honda dealership. Repair recommended. Honda corporate case opened.

The start stop system has failed to restart at a busy traffic light more than half a dozen different times after a 1 hour drive. Short drives do not bring this issue out. This got me stuck at a light, drivers annoyed honking and confused as I try to get my vehicle to start again. Turning the van completely off and back on again seems to get the van to restart again. I tried bring the issue up to the dealer when I brought it in for its first service, but the employee was extremely rude/belligerent and stated they would only do an oil change when I asked for help with this safety issue among other things. Will take to another dealer next service interval and try again. No issues known or warning lights on the vehicle prior. The van when it did this, error'd stating failure to restart or something along those lines. It happened so fast I don't 100% recall. After the issue the van would have no issues or lights on at all to even think anything had went wrong in the first place. This is a 2024, purchased new, vehicle.

Summary: engine seized due to internal bearing failure with metal shavings found in oil filter. Full description: my 2018 Honda Odyssey experienced a sudden engine failure around 116,500 miles. The dealer confirmed the engine is seized and showed significant metal shavings in the oil filter and pan. I have performed all maintenance according to Honda’s recommended schedule using the correct oil and filters. Honda corporate denied assistance based solely on mileage, even though this issue matches symptoms described in current NHTSA investigation pe25-001 (connecting rod bearing failure in Honda 3. 5l v6 engines). There were no prior warnings other than a brief check-engine light and rough running before the engine locked up. The vehicle was in motion at the time and could have caused a hazardous stall, serious injury, or death. Given that Honda has issued recalls for similar rod bearing defects in other model years (2015–2020) and this failure mode presents a clear safety risk (loss of power, engine seizure), I request NHTSA include my case in its investigation and compel Honda to extend recall coverage to 2018 Odyssey owners. I can provide dealer diagnostic reports, photos of the oil filter debris, and all maintenance records if needed.

On 10/4/2025, I was driving with my family on a single lane road around 7:30pm. The van automatically went into neutral "n" gear and there was a message displayed on the dashboard saying it is not safe to drive and asking me to pull over when it is safe to do so. Pressing the gas pedal didn't do anything. Eventually the car came to a stop. The car wouldn't allow me to shift the gear to d or p. A cop who was driving by, saw my situation and nudged the car to the side of the road because it was blocking other traffic. I turned off the car and waited for 5 minutes. Turned the car back on. This time the message displayed as "emission system problem". I was able to drive the van normally for another 30 miles to get back home. There was no obvious mechanical issues either before or after the car went to neutral. On Monday, I took the car to a Honda dealership. While driving there, the car still had "emission system problem" error. As soon as the person in the dealership turned on the car to get the mileage, the dashboard message went away. They did a diagnostic and said that they got a p0810 code. They reset the code and drove it for 10 miles trying to reproduce the issue. They couldn't reproduce it. I have driven the car for more than a week and I don't have the problem. However, a car automatically going into neutral while still driving on the road, seems to be a very dangerous issue. Please investigate this issue.

Vehicle shut off and put itself in park leaving a stop light. Was hard to restart.

On [xxx], while driving in traffic, my 2018 Honda Odyssey suddenly and without warning shifted itself into park. The vehicle slammed to a stop in the middle of an intersection, stranding my family and creating a serious risk of collision and injury. The vehicle would not move afterward and had to be towed from the scene. After the failure, the dashboard displayed multiple warnings: “transmission problem,” “stop driving when safe,” “emission system problem,” and *“blind spot information system problem. ” the gear shift indicator also blinked. The Odyssey has remained undrivable since the incident. The vehicle is at stockton 12 Honda in sandy, utah, where the dealer confirmed a hard transmission failure (ro #[xxx]). Honda corporate opened two cases (#[xxx] and #[xxx]). Despite my repeated calls and emails, Honda’s assigned case manager verbally denied coverage on sept 12, 2025, stating the denial would only be reflected in Honda’s internal case notes. This failure is identical to the defect described in NHTSA recall 19v-299, in which the transmission control unit (tcu) can reboot due to low voltage and cause the transmission to shift into park while driving. Although my VIN is not currently flagged, my Odyssey ex-l uses the same zf 9-speed transmission and tcu as affected trims. I have a tow record, witnesses, and video evidence documenting the event. The vehicle remains disabled, leaving my family without safe transportation. This is a serious safety defect that should require investigation and expansion of the existing recall. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2018 Honda Odyssey gear shifting switch letters are rubbing off. This caused the drive to click wrong button as they do not have letters to identify the functionality of the each button. This can cause accidents. I see many online forums customers are discussing the same issue. . Read more...

We were driving on the freeway when the car it stalled and place itself in neutral. We were unable to put it in park or drive. So we started googling while we were also trying to get a tow truck and we just decided to turn off the car and turn it back on and hoping for the best and we were able to put it back in drive and safely drive home definitely there’s a problem with the transmission or something electronical.

Rod knock diagnosed and confirmed by dealership July 15, 2025. Van is currently at dealership and is available for inspection. I have paused work to allow Honda (case 15705425) and now this team the opportunity to diagnose and inspect first hand. Inspection and first hand visuals have only been completed by certified Honda dealerships. All warnings and my concerns are documented in our ros with Honda dealerships. When any light or reminder came on, I immediately took the van to Honda for service. Safety: slow starts and sluggish acceleration. Noise that was not normal. Out to eat 30 minutes away from home July 13 and van wouldn’t start. Dealership thought initially battery but then kept van overnight and nod rock confirmed. Also repaired back suspension. Additional details: problem has been reproduced and confirmed. Have been experiencing slow start, van not driving properly. Our family went out to lunch July 13 and van wouldn’t start. Waited handful of minutes and then started. Immediately took to dealership next day. Honda dealerships have done all servicing and repairs on this van. (I was told there are 55 repair totaling $22k for your research purposes. ) Honda notified me July 29, 2025 that they will not offer any assistance and/or goodwill because of the age and mileage of the van. Escalating case 15705425 up Honda chain - we have been very loyal to Honda. As of today, July 31, 2025: van sits at dealership; has been there since July 14, 2025. I have been advised not to drive the van, esp on the highway. I want to keep the van and want to drive it for many more years. Took very good care of it and followed all of Hondas recommendations for servicing. Just put brand new tires front suspension (March 2025) and rear suspension (July 2025) on it as well. Appreciate your investigation. I’m working diligently to do the right thing and allow the proper people time to investigate the van before any work begins on the engine.

The powertrain jumps sometimes it is not smooth. The brakes does not hold too good.

The contact owns a 2018 Honda Odyssey. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond as intended. The contact stated that the failure has caused the vehicle to hesitate while attempting to accelerate. The contact stated that the failure had occurred on several occasions while driving on the interstate and the freeway. A dealer was contacted. The vehicle was taken to the dealer, where it was diagnosed, and determined that the software needed to be updated and the vehicle needed to be driven approximately five thousand miles to correct the failure. The vehicle was repaired, and the transmission was replaced once before. The manufacturer was notified of the failure; however, the warranty department failed to return the call. The approximate failure mileage was 108,900.
