2019 Honda Odyssey: sudden unintended acceleration

Filed Oct 11, 2026 · Fuel system · SC

The vehicle experiences frequent and unpredictable loss of acceleration when starting from a stop. The issue is intermittent and difficult to reproduce under specific conditions. At times, when the accelerator is pressed, the vehicle fails to respond or moves only slightly. Even when additional pressure is applied to the accelerator, there may be little to no response, followed by a sudden and forceful surge forward, as if the accelerator had been fully depressed. I understand that fuel-pump recalls have been issued for certain vehicles of this make, model, and year; however, my vehicle's VIN is not currently included. Based on the symptoms and the severity of the issue, I believe my vehicle warrants further investigation to determine whether it should be included in the recall. This problem first began in 2020, following my purchase of the vehicle in 2019, and has repeatedly created dangerous driving situations. When attempting to cross oncoming traffic from a stopped position, the vehicle's failure to accelerate presents a serious risk of a broadside collision. On multiple occasions, my wife has been left stranded in the middle of an intersection because the vehicle failed to respond to the accelerator. Given the persistent nature of this issue and the significant safety risk it presents to the driver, passengers, and other motorists, I am requesting a thorough investigation into the cause of this malfunction and a review of whether my vehicle should be covered under the applicable fuel-pump recall or receive other appropriate corrective action.

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

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.

The contact owns a 2019 Honda CR-V. The contact stated while driving at various speeds, the vehicle lost motive power while depressing the accelerator pedal. The contact repeatedly pumped the accelerator pedal before the vehicle surged forward and resumed normal operation. No warning light was illuminated. The manufacturer was notified of the failure and referred the contact to a dealer. The vehicle was taken to the dealer and test-driven; however, the failure could not be duplicated. The contact was informed that because there was no warning light illuminated, the vehicle could not be diagnosed. The contact then received notification of the federal safety agency Campaign Number: 23V858000 (Fuel System, Gasoline) which was linked to the failure. The dealer was made aware of the issue and the contact was informed parts were not yet available for the recall repair. The contact stated that the manufacturer had exceeded a reasonable amount of time for the repair. The failure mileage was unknown. Parts distribution disconnect.

On multiple occasions when traveling at a low rate of speed when the accelerator is pushed there is no response for up to 2-3 seconds then the car suddenly accelerates forcefully because the gas pedal has been pushed to the floor with no response. It has mostly happened when we are making a left hand turn and have slowed. Due to the seconds of delay we have been almost t boned and are hesitant to make a left hand turn if there is any traffic because we don't know if the car will immediately accelerate or if it will hesitate. We are able to reproduce it to some extent by accelerating the car to about 5-7 mph, letting off the accelerator and then reapplying pressure to the accelerator. We took the car to the dealership and they reproduced it and contacted the Honda techline who told them it is normal. It has been scary for myself and my wife and does not feel normal for the car to have a complete delay in response and then over respond.

This is for the 9 speed transmission. Frequent erratic shifting first and/or possibly second gears. Engine revolutions increase and then gear engages with lurch or tire sqweek. One incident (and only one) of unintended acceleration after mid-range gear change on expressway without cruise control active or foot on gas pedal. Occasional clunk noise at mid-range shift. I do not use ECON mode. I have never used the paddle shifters. 2019 Honda Odyssey EX, currently about 27K miles. The vehicle is operated above 5K feet altitude and frequently above 9K feet altitude. Often in the same day. At last dealer visit, service tech indicated that there were no recalls or bulletins. The transmission was not serviced. My next transmission service is recommended for 30K miles. I subsequently made local service rep aware of California based class action lawsuit for these issues and I was passed to service manager. He indicated that he has no fix. I called Honda corporate service and I disconnected the call when the representative asked for a detailed log of incidents, which I cannot provide. My last inquiry to local dealer service tech about installing the 10 speed transmission (available in a higher trim level in 2019) in place of the 9 speed has gone unanswered. I originally thought that these issues affected only my van until I read about other experiences on the internet. The unintended acceleration concerns me.

While driving, if I don't make a complete stop (say at a yield sign), and I accelerate, there is a 1-2 second gap between when I press the pedal and the van actually goes. This can happen while fully stopped, while yielding, or even while getting onto the highway. Taking it back to the dealer has yielded only firmware upgrades to the software and recommending a $400 transmission flush. This happens more frequently while in economy mode, but also happens in sport mode. This has been going on for about a year now. The dealer has stated there is nothing wrong with the vehicle, but if I ever have to suddenly accelerate it could mean I will get into an accident.
