2019 Honda Odyssey Powertrain (other) Problems

My name is [XXX], we bought a brand new 2019 Honda Odyssey Elite, we have had problems with this vehicle since day one. They have lied and covered up the issues with this vehicle starting with the infotainment center, transmission slippage, fuel pump and the front camera has been overheating giving us the message that it is overheating and all the lights come on. They have stalled us on these issues and now the extended warranty is up and we want something done about this. We have babied this vehicle the entire time since new and it seems like one problem after another, at this point we are very disappointed from the way we are being treated from Honda. The latest is the front sensor on the front mirror that pops up all the lights on the dash, no one seems to be able to duplicate the problem, now they are on all the time and conveniently the extra extended warranty we bought have since expired, there was a lot of recalls on this vehicle and no one ever seems to be able to send us the recall letters. We really thin the mirror sensor and the transmission are definitely safety issues especially when the mirror shuts all the safety off. The transmission shifts hard at times and we pray that Honda will step up to the plate and do the right thing and fix the other recall issues on this same vehicle as well. We have other Honda vehicles that we have not had any issues with, we just can't understand why we are being treated in this manner, we just want the vehicle fixed.

Vehicle began to misfire on cylinder 3. As the issue continued more cylinders stared to misfire. Next was number 6, then 2 increased up the engine. Air fuel ratio was 1.6. Assuming it was fuel/air/electrical in nature, the spark plugs, and fuel injector were changed and air intake and upper valves were cleaned of carbon build up. All gaskets replaced by new. Discovered and replaced a bad egr valve. Last codes that the car displayed before towing to dealer were many misfire codes and 2 engine/transmission communication errors. Dealer shop discovered air fuel ratio of 1.35 and checked all work before. Discovered fuel pooling and some shiny areas in the engine from scoping it. Decided that if was a bad engine with internal failure and transmission. Quoted me $17000 (about the same value as the vehicle if it was jn very good condition) for a new engine and transmission or $6800 for a used engine alone at risk of replacing transmission as well assuming communication errors do not go way or transmission fails further. I have called honda corporate my reference # 16624114. I requested goodwill repair due to recalls and class action lawsuits related to connecting rods in engines of similar cars and model years. And transmissions recalls for similar cars and model years. Goodwill is unlikely but pending.

My 2019 Honda Odyssey has a recurring and dangerous hesitation-to-accelerate defect that began within a few weeks of purchase and has continued for approximately one year, occurring roughly once every 5 times I drive the vehicle. The failure occurs when accelerating from a stop or slow speed, most critically when crossing traffic — for example, turning left across an oncoming lane or pulling out into a road with an approaching vehicle. When I press the accelerator pedal, the vehicle fails to respond for approximately 2-3 seconds. The pedal feels unresponsive during this delay. The transmission then suddenly engages and the vehicle accelerates abruptly and rapidly. This has created several genuinely dangerous situations. On multiple occasions, while attempting to cross traffic or complete a left turn, the vehicle did not move as expected while another vehicle was approaching, leaving me exposed in the roadway during the delay before the sudden acceleration occurred. These were not near-miss "in my head" moments — an approaching vehicle was close enough that the delay put me at direct risk of a collision. I brought this to my Honda dealer for inspection. The dealer was unable to reproduce the issue during their test drive and found no diagnostic trouble codes. The vehicle was returned to me with no repair performed. I have researched this issue and found it to be widely reported among other 2018-2020 Honda Odyssey owners, with symptoms matching mine almost exactly — hesitation from a stop followed by sudden, uncontrolled acceleration, particularly when crossing traffic at intersections. I am also aware this transmission (9-speed, ZF-sourced) is the subject of a class action lawsuit (Browning, et al. v. American Honda Motor Co.) alleging a defective transmission programming/design issue causing this exact symptom pattern. This is an active and ongoing safety hazard: the vehicle is unpredictable during exactly the maneuvers (left turns, crossing traffic, merging) w

Apr 13, 2026

The vehicle is experiencing a dangerous hesitation during acceleration at low speeds, immediately followed by a sudden, violent forward lunging motion. When attempting to accelerate from a complete stop, or when rolling at low speeds (such as yielding at a roundabout, turning through an intersection, or merging into slow-moving traffic), the vehicle suffers from a distinct **lag or complete failure to accelerate** for several critical seconds. In an attempt to get the vehicle to move out of harm's way, the driver naturally applies more pressure to the gas pedal. The vehicle's transmission then randomly responds after a few seconds with a violent lunge forward, spinning the tires and causing the vehicle to surge unpredictably. This unpredictable behavior creates an immediate and severe safety risk to the occupants of my vehicle and others on the road: 1. Intersection Collisions: The sudden lag leaves the vehicle stranded in oncoming traffic during turns, while the subsequent lunge threatens to overshoot the intended lane. 2. Pedestrian Hazards: The sudden, uncontrollable lunging makes low-speed maneuvers in school zones, crosswalks, and parking lots incredibly hazardous. 3. Drivers behind behind me do not expect a vehicle to suddenly stop accelerating after it has begun to move forward. I have taken the vehicle to the dealership we're we were able to reproduce the issue and Honda would not offer a fix. I thought I was going to get my entire family killed the other day when I pulled out at a stop the van hesitated in the middle of the highway for a few seconds before lunging forward. This is an intermittent issueand the severity varies each time, but is commonly cited online.

Engine failure. Not available for inspection. Engine replaced and damaged engine return for core charge. While driving on the highway, without any for warning, engine stalled, loss of power and dash read “emissions system problem “. Vehicle was towed to Honda of Denton for diagnostic testing. The engine stalling and loss of power at highway speeds caused a great risk for my family in the van. We impeded traffic and could have caused an accident. There were no warning lights and/or engine system issues leading up to the engine failure. Honda stated that it’s is a common issue with the internal engine bearing failure. They also confirmed that my VIN is not listed on the recall list for the 2 million engines effected. Honda quoted a LKQ engine replacement. Declined and had replacement done at Caliber Collison.

I am writing to open a formal complaint regarding a serious transmission defect in my 2019 Honda Odyssey (VIN: [XXX] ). My vehicle is currently exhibiting symptoms that directly match the 'Transmission Programming Defect' documented in ongoing litigation, specifically symptoms: while accelerating produce rough and delayed shifting; sudden jerking, sudden, harsh accelerations and decelerations; and a sudden loss of power. I am aware of Case No.XXX (XXX v. American Honda Motor Co.) and Case No. XXX (XXX v. American Honda Motor Co.), which allege that the 9-speed ZF 9HP transmission in my model year suffers from a design defect. These transmission failures create a significant safety hazard. Recently my van report code as transmission system problem the second time. We got mechanic checked and confirmed it is transmission issue. The first time when it happened, we drove the van on highway and suddenly it lose power and slow down by itself. there was no response even we applied gas. We went down highway and drove to a close-by repair shop. they replaced some part for us but it didn't resolve the issue. This time since the error comes, it won't speed up in lower speed except the speed goes beyond 40-50 miles plus. when we back the car, it responses slow or none. it comes with big noise also now. it definitely gets worst. The very common issue when you stop and start to move, it never responses from the beginning even we applied gas, even the passenger can feel the reluctance. it also happens when the van turns. we also had the experience when driving on the highway, it speeded automatically without driver applied the gas. It feels like someone pushing us behind. there was Transmission Control Unit recall for 2018-2019 Honda Odyssey (Touring/Elite). Honda actually knows the issue but they didn't reveal this to their customer. This brings life threatening concerns on the highway.

My 2019 Honda Odessey has had transmission issues since the very beginning. I've experienced jerking/shaking, hesitation before accelerating, delayed shifting, sudden loss of power. Fortunately none of this has resulted in any accident or injury. Unfortunately, yesterday (4/4/2026) I got charged $271.34 to have to transmission warning light read only to be told, "we cleared all dtc then test drove the vehicle. No dtc found after we drove the car...if the consumer complain again he will have to replace the transmission." Of course the warning light appeared again today. The dealership seems to be completely unaware of the multitude of transmission issues documented even though this appears to be a known and well documented defect based on the class action lawsuit Browning, et al. v. American Honda Motor Co., Inc., et al. They charge me for the analysis and send me on my way as if they have no idea what is going on with my vehicle. I am the sole owner and have kept the vehicle well maintained at Leith Honda, 3940 Capital Hills Drive, Raleigh, NC 27616 and I have had all manufacturers recalls handled in a timely manner. I'm sure they can provide service records if needed. The bottom line is they are not being fully transparent and I am paying for their lack of transparency and more importantly putting me and my family at risk by not disclosing the potential risk due to the faulty transmission in these vehicles.

I am reporting a safety issue involving my 2019 Honda Odyssey transmission. Since early ownership, the vehicle has had ongoing hesitation and delayed response when accelerating, especially during gear shifts. Over time, this condition has worsened and now includes intermittent loss of power when pressing the accelerator, followed by sudden jerking or lurching forward. The most serious incident occurred recently when the vehicle unexpectedly shifted into park while moving in a parking lot, creating a dangerous and unsafe condition. Additionally, there have been multiple instances where the vehicle hesitated in intersections, creating a risk of collision due to lack of response when attempting to accelerate. Honda dealership technicians have acknowledged that these vehicles are known to have rough or problematic shifting, indicating this may be a broader issue. The final issue has resulted in the vehicle being towed to the dealership for a full evaluation.

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.

Feb 14, 2026

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.

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.
