general problems of the 2019 Honda Odyssey - part 1

My 2019 Honda Odyssey is currently diagnosed with a connecting rod bearing failure, which matches the safety defect in NHTSA recall 23v-751. While my VIN is excluded, I am reporting this as part of the NHTSA investigation pe25-008. For several months leading up to the failure, I noticed a faint, repetitive knocking sound coming from under the hood. During my regular service visits to authorized Honda dealerships (including a visit in December 2025 at approximately 80,000 miles), I mentioned these unusual noises and asked the technicians to verify the vehicle's safety. On at least one occasion, repairs were made to the steering system to address noises, but the engine knocking persisted and eventually worsened until the rod bearing failure was confirmed in January 2026. This defect presents a serious risk of sudden engine seizure and loss of motive power at highway speeds.

Vehicle intermittently loses propulsion during acceleration when merging. Engine rpm remains low despite throttle input. After a delay, transmission re-engages abruptly with a metallic scraping noise. This creates unsafe merging conditions. This happened today, 2/14/2026 in 4 instances in the same trip. It has also occurred approximately 50 other times over the past six months when the mileage was as low as 66,100 miles.

Our 2019 Honda Odyssey ex-l was our primary family vehicle. We conducted all routine maintenance as required by Honda, including transmission fluid exchange. Our vehicle experienced rough shifting consistently and at 102,000 miles experienced a total failure in the transmission dog clutch, with emissions lighting also being present. Vehicle required a tow to Honda and was cited" internal failure in the transmission. The confirmed related dtc's are p0841: transmission fluid pressure sensor/switch a circuit range/performance; p0844: dog clutch malfunction; p0170a: dog clutch abnormal operation. Parts $:5,736. 73/labor $2,385 plus fluids and freight. We were not aware Honda used the zf transmission during this year model and experiencing rough shifting up to 102,000 miles which prompted our investigation. Thankfully, the car was parked however, had this been while on the road, this would have presented a major safety and risk to our family and others. This has set our family back quite a bit as we have to replace the transmission and cannot guarantee the new one won't provide similar issues. Honda denied our good-will assistance request. We bought a Honda under the assumption it was a reliable brand. We will never buy Honda nor recommend again. Terrible experience.

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.

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 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 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.

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.

The contact owns a 2019 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. Additionally, the vehicle stalled with several unknown warning lights illuminated. The contact received notification of NHTSA campaign number: 23v858000 (fuel system, gasoline). The vehicle was taken to the dealer, and the recall repair was performed. The contact was informed that the transmission needed to be replaced. The contact was informed that the failure was possibly due to a failed fuel pump module. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The contact was informed that the repair was not covered under warranty or recall. The contact was advised to contact the NHTSA hotline to report the failure. The failure mileage was approximately 150,000.

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.

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

Ever since we bought the car, the car has hesitated when we step on the gas pedal. It will then jerk forward, which makes it difficult to merge into traffic. There is a safety concern as it is unpredictable about when it will happen and when the car will start to go.

Intermittent hesitation to accelerate.

Auto stop start feature caused car to stall at a traffic light. Could didn’t not restart when brake pedal was released. Car did not restart until door was opened and key was cycled several times.

When trying to accelerate from slow/ stopped, the car struggles to get into gear. I have on numerous occasions been merging or getting onto another road from a stop sign and the vehicle will start to go just slightly and then stall before suddenly jumping into gear. It has caused me to stall in front of oncoming vehicles even though im careful to not go unless there is noone within a long distance from me. I have taken it to the dealership and there are no codes for transmission or any other issues. Im not sure what the issue is but it is very unsettling.

Delayed transmission engagement when accelerating from a stopped position. When the accelerator is depressed the transmission hesitates and does not shift for a few seconds. This is very unsafe when trying accelerate into traffic or cross roads. This has been an on going issue with this transmission.

Shortly after owning we started noticing sporadic jerks between 24-29 mph that felt like a hard up shift. We immediately brought to our local Honda dealership where they performed a software update. We were told that the vehicle struggles to shift while under load. Recently our van was making a whining noise and seemed hard/delay to accelerate in drive as well as reverse. Almost felt like I was in neutral, but was not. No warning lights were on, but something was not right so I went home. The next day it would not start and lit up every warning light. We had it towed to the dealership and was told battery was shot so they replaced. On way home it was still hard to accelerate so we brought it right back to the dealership and have been told a new transmission is needed. We have had all maintenance done at dealership prior to this. In fact, the vehicle was just in 3 weeks ago for an oil change and everything looked great. These issues have occurred without any warning lights or diagnostic alerts, making them unpredictable and dangerous. A transmission should not fail without any particular warning to the driver. It seems these transmissions have had a defect from the date of manufacturer that cause malfunctions, premature failing, costly repairs, and most important major safety concerns. Honda needs to be held accountable.

The lkas and several other lights are on in the vehicle and no one has been able to provide any answers as to why. Nor can the problem be fixed. There is also a problem with the transmission. Upon acceleration there is a hesitation that the car will not engage.

The contact owns a 2019 Honda Odyssey. The contact stated that when the vece was turned on on several occasions, the "emission system problem,brake system problem, brake hold system problem, power steering eps problem, vehicle stability assist vsa problem, hill start assist problem, and road departure mitigation system problem" messages appeared. The vehicle was taken to a dealer where it was diagnosed that the fuel injector kit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of failure. The failure mileage was approximately 120,000.

Transmission slipping randomly due to software issues.

When switching gear in low speed, car often jerk . Car also jerk when switching from reverse to drive froward gear.

While driving at 25-30 mph, all of a sudden the 2 warning signs came “transmission system problem” and “blind spot info system problem. ” the “d” in the dashboard started blinking. When I put the vehicle in park at a stop light, the “p” also blinked. After a couple of minutes of this I pulled over and turned the car off. A few minutes later I restarted the engine and these warning lights have not come back in the last 5 drives. I read online that this may be a software glitch that needs updating (which I think is a manufacturer defect). I do feel like the car was a bit jumpy while these warnings were going off and I was terrified that it would put itself into park while I was driving and cause an accident.

Since 2023 around August I felt lose of power while driving but I thought its because of the gasoline I used so I didnt care much , thereafter this loss of power problem persisted since then so I took to the dealership at battison Honda at nortwest expressway in oklahoma , but they said my vehicle has no issue , but this loss of power issue was not resolved but on 1st week of February I was about to crash on road due to loss of power so took the vehicle to dealership and they said it was due to the trasmission issue and I replaced it as it passed the 5 year powertrain warranty dealership said I have to pay it full , I fight with them for 2 weeks atlast they said I have to pay 5000 dollar . So I paid the amont and they said the transmission has replaced , but still I have some hesitation while accelerate and the same issue of loss of power during acceleration happening , can you please help me to resolve this issue as its not only about money but due to safety concerns , I dont want to deal with trhat dealership anymore . Please help me during this difficult situation . Thank you .

Dash warning lights for engine code p2019 associated with the fuel injectors come on and off intermittently. Honda has said my injectors are not under recall despite other 2019 Odysseys having been recalled for this same issue. Transmission has expired hesitation in shift moving from a complete stop and acceleration.

Vehicle has hard shifting up and down. Loud clank when up shifting or down shifting at random times.

The vehicle has been occasionally stalling starting early 2024, maybe sooner. I had the fuel pump recall done recently. The vehicle is still stalling, and it seems to be getting worse. The stalling happens when driving at speed, even over 70+ mph. No warning lights. But rpms drop to almost zero for a few seconds and accelerator is unresponsive. Then it comes back after a few seconds. This is dangerous. Especially on busy highways.

No acceleration on freeway/highway.

See attached document for complaint.

Over the course of the 38 months that we have owned the vehicle, random transmission slippage has been present on this 2019 Odyssey. I mentioned the slippage to the service advisors at the dealership when taking the vehicle in for oil changes. The technician was “not able to replicate the problem. ” the slippage was always a safety concern. The van is highly unpredictable on acceleration, making it dangerous to try to pull into traffic, for example, since the driver never knows whether the van will accelerate on demand or not. Other times, the engagement will occur gradually, causing the van to accelerate sloooooowly, despite the driver having significant throttle applied. The display now reads “transmission system problem” and will not shift out of park. I had it towed to the local auto repair shop to be diagnosed. The transmission needs replaced.

We have had issues with the transmission multiple times. After coming to a stop, rolling forward, and then pressing the accelerator the vehicle hesitates and won't immediately move forward. It will suddenly engage, often squealing the tires and jerk into forward motion. This puts us and others at risk because it causes a delay in pulling into traffic and has made for close calls with oncoming traffic. We took the vehicle to a local shop and they also noticed the issue with the transmission. We took the vehicle to a Honda dealership for service and while they stated that they could not duplicate the issue, there was a software update that they completed and stated that they thought it would take care of the issue. We are still having the issue and plan to take the vehicle back to the dealer for more investigation. We have not had any warning lamps or other messages. Upon researching this, there are class action lawsuits in the works related to this issue on 9 speed transmissions used in various Honda models during this timeframe. Honda has not recalled or extended warranties to cover these issues. It looks like Honda has sent technical service bulletins to nationwide dealers acknowleding the issue but has failed to find a fix for the problem. As in our case, Honda has done software updates which may mask the issue. Below it asks for the date that the incident occurred - this occurs at least weekly, sometimes more frequently.
