2019 HONDA ODYSSEY Power Train Problems

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.

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...

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.

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.

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

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

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....

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...

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.

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.

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...

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

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.

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.

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

Vehicle jerks at about 25mph when it’s idled in 1-2rpm. Sometime at acceleration and won’t move up rpm. Vehicle got fuel injectors and transmission fluid replaced and still have issues. Vehicle in shop now with less then 2,000k before power train warranty up even though I’ve been dealing with it for over a year. Dealer said transmission fluid was down quart 4 months after they changed the transmission fluid. They were able to replicate jerk but couldn’t replicate sound of something clicking over while idle. I have it on video. I think since Honda never fixed the issue in the first place it caused additional damage and all the want to do is add more fluid and call it a day.

The contact owns a 2019 Honda Odyssey. The contact stated that when the vehicle 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 the failure. The failure mileage was approximately 120,000

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...

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...

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 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.

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.

sorry, I should make the complaint earlier since I just know I can submit it here. I have a 2019 honda odyssey EX-L since 2019 but I only have 22K miles. Starting from 2023, the vin could not pick up speed when we pushed the oil paddle; the transmission got stuck and the van could not be speed up when it was needed in highway. We came across the dangerous situations for several times. We contacted the local honda dealer for several times. They insisted that there was not any problems but they suggested we change the transmission fluid with less then 19000 miles !!!. But even we changed the fluid , the van seemed better for 2 months. I contacted honda USA. But they did not pay any attentions!!!! In the end of Jan 2025, I was making a left turn while the van got stuck there ; I...

While driving at 25-30 mph, all of a sudden the 2 warning signs came up: “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.

Does not accelerate on the highway/freeway. Took it to dealer shop, several times over the years. First 2-3 years, they say they did not find any issues. Last year, they said it was transmission issue. We took it to other repair shop, he said it was computer system failure.

No acceleration on freeway/highway

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

Currently own a honda odyssey 2019. The transmission is unstable at times. From a speed of 25-30mph, it performs hard shifts i think from the 3rd gear. We can really feel the jerk of the van along with a sound like metals slipping or something. It doesn't always happen therefore the dealer could not fully diagnose it and called it normal or wait for it to get worse. Yeah right!

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.

- Step on accelerator and no acceleration, - When at stop then gas there is hesitation with extra slow accelerator. - Shifting from 1st to 2nd there a jerking and hard shift which something cause loud noise. - Reported multiply times to dealer and indicated its normal (Replace purge valve) no help.

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.

While driving down the interstate going between 55-60 mph van began to downshift and rpm’s started rising but gas pedal didn’t accelerate. Then the next day I got stranded on a highway because the van locked into neutral before I could pull into a parking lot because of traffic, then it finally went into park(we were trying to get it back in drive obviously). I was stuck blocking traffic for almost an hour with 3 kids and an infant in the car. Finally, restarting it several times worked and i was able to pull in and wait for a tow truck. This almost happened on the interstate. Someone is going to be seriously injured or worse because we almost were. Honda I supposed to be known for safety but right now, I may just switch to Toyota because apparently this issue is known and they just don’t care enough about...

Step on accelerator and no acceleration, hesitation and have to push farther down on accelerator. Sometimes that works other time I have to let of accelerator and push again to go. Nearly cause accident multiple times.

Transmission went out at 120,000 miles.

The transmission on this van has acceleration issues. When trying to accelerate the van will on occasion have hesitation of a few seconds. This has left me in situations when merging where I have almost been hit. The acceleration at times is not responsive. I’ve noticed it when trying to apply urgent acceleration, such as trying to cross an intersection, and when I accelerate a little, let off the gas, and accelerate again. A Google search finds many people with the same issue. This is a major safety concern since the van does not apply acceleration when expected and can leave a person vulnerable to being hit. This has been happening to me for years but I didn’t know I could report this. Happened today.

Honda Odyssey 2019 slips during highway speed and has no acceleration while the engines rpm goes up. Very dangerous at highway speed and then will have a large clank noise and go into gear. Honda doesn't acknowledge the issue with their 9 speed transmission but their are tons of complaints on the web with the same issue I have. It happens at lower speed too at stop lights and is a safety concern for me when my wife is driving out children around.

When car stops and Am I go to accelerate. The pedal. is dead and won't respond. Take. 3 seconds for it to accelerate. And if you're foot in an accelerator. it will take off and squill the tires.

Prior to this recall, we had noticed an acceleration issue with the car. One day, during our travels, we encountered a severe stall, which could have been a dangerous event. Just as we were grappling with this situation, news of a recall reached us, but unfortunately, the fuel pump required for the fix was unavailable. It was only when the HondaLink app suggested that the dealer could replace the fuel pump that we found a glimmer of hope. Immediately, I secured a reservation for March 15th, 2024. However, upon reaching the dealership, we were informed that the required part was not in stock. Frustrated, I lodged a complaint with Honda, outlining our predicament. Today, on April 4th, 2024, I received a response from them, stating that they would address the issue once the part became available. However, this leaves me in a precarious position. Who will be held accountable if...

Sudden Loss of Acceleration/Unpredictable Acceleration: Pressed accelerator to enter highway from rolling stop going around 10-20mph. ZF 9-Speed transmission hesitated, attempted to downshift & vehicle suddenly lost transmission & possibly went into neutral and/or transmission failed on highway. Dashboard indicated Emissions System Problem" & "Transmission Problem" Vehicle would not shift back into gear & vehicle was subsequently towed. Prior to this event, vehicle had occasional 0.5 - 2 second hesitations when downshifting & exhibited rare occasional metal clanking sounds when downshifting beginning around 70,000 miles. Additionally. transmission had unpredictable significantly delayed shifts that resulted in subsequent surges of power that were enough to screech the tires on acceleration.

The transmission slips or doesn't engage appropriately. The van lurches forward at intersections and slips, pauses with a loud clunking noise at lower gears when driving in town. This morning, I attempted to cross a double highway...pressed the accelerator, nothing happened, then the vehicle lurched forward, stopped again, then lurched forward again all with the accelerator pressed down. I was almost hit broadside while crossing the highway. This is not the first time this has occurred. Multiple people in our household drive this vehicle and all have reported the same concern. I've asked about this every time I get routine maintenance but Honda dealership says it's working as designed and they've witnessed this issue in other customer reports. This is a significant safety risk!

Driving on highway suddenly multiple warnings ⚠️ lights on (about 10) warnings lights like check engine, transmission system, power steering system brake assist ,holding brake system, line departure assistance, hill assistance, emission system, ACC system, VAS system, blind spot assistance and lack of power hitting gas (Accelerate pedal) no response car slow down by itself becomes 20mph on 55mph highway very scary this happened four times in one month.

Vehicle will "neutral out" on acceleration and make a whizzing noise. This occurs every time we drive this vehicle. It loses a great deal of power when this happens and feels like it is never going to regain speed. Finally, after 5-10 seconds it goes back it to gear but not before you almost get rear ended

The van had 75k miles and would lose propulsion on the highway with no warning and no dash light coming on. van would slow way down causing other drivers to hard brake behind us, Then finally go back into gear and drive like nothing happened, couple days later the same thing would happen. We took it to Honda and said the transmission will need to be replaced.
