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

- Mobile, AL, USA

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.

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 their customers to recall and fix it.

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 an accident were to occur due to this fault? Neither Honda nor the dealer seems willing to shoulder responsibility. Certainly: In their response, Honda has essentially washed their hands of the matter, stating that it is up to me to pursue further action. They suggested that I could either escalate the issue with the NHTSA or explore legal avenues. Despite this, they have chosen to close my query, leaving me feeling abandoned and unsupported in this ordeal. Feeling increasingly uneasy about driving a car with a known faulty component, I am left with no choice but to consider reporting this matter to the NHTSA for serious intervention. I implore Honda to take decisive action, whether it involves replacing the vehicle or compensating for the trauma we've endured during this time. Each time I get behind the wheel of this car, I am acutely aware of the risk posed by the defective fuel pump. It is imperative that this issue is addressed promptly and responsibly.

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

- Morganton, NC, USA

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.

- Drumright, OK, USA

Rear lift gate ceased operating, unlocking or opening. Later received errors on dash for blind spot malfunction and transmission error. Dealer says it is an issue with water leaking into the rear chassis getting into the exposed electronics.
