2019 Honda Odyssey: complete transmission failure

Filed Aug 21, 2026 · Acceleration, Electrical · FL

I'm filing a formal safety complaint regarding my 2019 Honda Odyssey, VIN [XXX], & requesting an engineering-level review by American Honda. I've brought this vehicle to an authorized Honda dealer numerous times for recurring & increasingly serious electrical, engine/power-loss, & transmission problems. Despite thousands of dollars in repairs, the problems continue. The vehicle has unexpectedly shut off/lost power; the power sliding doors have failed & required manual opening; low-battery warnings have appeared; & the radio/infotainment system repeatedly loses power and resets. I have photographs showing the message: “Anti Theft System–This system has lost power.” More seriously, the vehicle has malfunctioned in Park, Reverse, while shifting into Drive, & while turning. Most recently, the transmission would not engage properly and the vehicle had to be shut off and restarted multiple times before it would go into Drive. Delray Honda documented this transmission failure/no-drive incident on its August 2026 repair order. In May 2026, I brought the vehicle to Delray Honda for a Check Engine Management System warning. Repairs were performed, but the warning returned within days. Delray Honda then replaced the power distribution module, costing me approximately $2,000. I've spent thousands more dollars addressing these recurring problems without resolution. I understand Honda/the federal safety agency Recall 19V‑299 involved certain 2018–2019 Odysseys and a loss of power to the Transmission Control Unit. My Odyssey appears to have been manufactured around the time of those Hondas that were covered by that recall. I'm not claiming without diagnosis that the defect is identical, but the similarity of the symptoms warrants an urgent investigation. I request that Honda open a formal safety case, review my complete service history, DTCs and TCM/PCM data, determine whether my vehicle has the same or a related defect, and review my prior repair costs for reimbursement. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

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. I hope this complaint can save lives and family INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(

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.

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.

Front camera appears to have gone out in 2025. All safety features inoperable and constant flashing of warnings making it impossible to determine if anything is actually wrong. Collision mitigation failure, blind spot failure, transmission failure, brake system failure, blind spot. Those control etc. Honda has confirmed its issue with front camera.

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 the federal safety agency 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 the federal safety agency regarding 2018–2019 Odyssey models. I am requesting that the federal safety agency 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.

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.

today ( Dec 30, 2025) . my wife was driving my HONDA ODYSSEY on Highway 287 east NJ ( closed to livingston NJ ) . Here is the whole thing : The ODYSSEY suddenly stopped while my wife was downshifting. At that time, there was a car in front of our car at least 30 feet away. Once the car stopped almost completely. Some red warning letters were shown on the front dashboard. But since we all filled in in a big panic, no one saw what those words were. At that time, we felt the minivan vibrating. That is all we could recall since we were still trying to calm down. I am not sure it was still the same problem with the transmission we reported months ago. That is the whole store for today. And I also attached the last note I sent to you. Hi , To whom it might concern, To further the conversation, we had talked with the local Honda dealer, and they had test-driven it several times, but they insist there are no problems at all. They suggested that we replace the transmission fluid to improve the performance. We replaced it in the dealer store. But from the fall of this year, 2025. We feel the odyssey has the same problems again : 1. The vehicle struggles to accelerate quickly when the accelerator is pressed. 2. The vehicle accelerates, but there is a noticeable jerking sensation. 3. After pressing the accelerator, the engine RPM increases significantly (the engine noise also grows louder), but the car itself does not accelerate immediately. It takes several seconds before any noticeable increase in speed occurs. I checked online I noticed that in some cases, some odysseys stop on the highway and cause some injuries, which is terribly I also sent a note to Honda USA, and I got a reply, but it is useless. I do not know what I can do. I saw there was some recall (due to the transmission) on Othe dyssey touring model and elite models, but I wonder if there is any recall on my Odyssey EX-L model.

My 2019 Honda Odyssey EX-L has had sporadic errors happen: Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, Blind Spot Info System Problem. These errors have shown up before sporadically and the dealer, DCH Honda of Oxnard was notified April 27, 2023. They could not replicate and did not respond in writing that something was wrong. The errors went away on their own. 3 weeks ago, the errors showed up again, this time also including a transmission system problem warning. The car was taken to Honda in Valencia and they ran a diagnostic and recommended the transmission be replaced or they would give us $2500 for the car. We opted to have a well reputed private transmission mechanic replace the transmission. After doing so the errors are still there. The transmission system problem error even showed up sporadically the very same day we picked the car up. There is no rhyme or reason to these errors other than perhaps a faulty windshield camera, which takes 5 minutes to replace but Honda wants to charge $2k. We also experienced the delayed shifting due to the poor 9 speed transmission and vcm design. It was quite scary to have a car full of children making a left turn on a busy road and not have the car kick into gear but rather slip. Installing a vcm tuner to bypass the computer shifting helped as well as not driving the car in Econ. Honda knows they made a bad car and while Honda Pilots and other models have had recalls related to the transmission, I am atill waiting for the federal safety agency to take action and include my lemon Odyssey as well. Replacing the transmission cost me over $7k and it may not have been necessary in the end if in fact these errors were related to the camera.
