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.

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.

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 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.

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. 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.

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.

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 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.

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.
