Filed Oct 13, 2026 · Fuel system · 136,000 miles · NJ

The contact owns a 2019 Honda Odyssey. The contact stated that while attempting to accelerate from a complete stop at a traffic light, the vehicle hesitated and failed to respond. The vehicle responded after several attempts and operated as intended. The vehicle was taken to an independent mechanic, where it was diagnosed that the fuel injector had failed and needed replacement. The contact notified the manufacturer of the failure, and a case was filed. The failure mileage was approximately 136,000.

When I go from a dead stop, it 7/10 times has a long hesitation before going. Sometimes its up to 5 seconds of hesitation. I've almost been hit crossing oncoming traffic. I have mentioned it to the Honda mechanics who say they don't see it when testing. I'm always afraid it's going to stall. Also, sometimes when I let off of the gas it almost feels like a brake is being applied as I approach a stop. I've changed the transmission fluid and used gas additives to no avail. I see some models of odyssey had a recall for this but for some reason not mine.

Safety Concern: Severe Transmission Lag and Hesitation on Honda 9-Speed Vehicles. The Honda 9-speed automatic transmission exhibits dangerous downshifting hesitation and delayed shifting while cruising at highway speeds. When attempting to pass another vehicle or accelerate quickly for extra power, the transmission frequently experiences a severe lag, causing a total lack of throttle response (a "no response" mode).This sudden loss of acceleration at highway speeds is highly alarming and significantly increases the risk of a rear-end or overtaking collision, creating an immediate safety hazard for the driver and other motorists.

when trying to accelerate from a stop or slow roll velocity (e.g. at a yield sign), there is a hesitation between the time I press on the accelerator and when the vehicle moves. This becomes a hazard because if there is a delay in acceleration, I could be hit by oncoming traffic. The fuel pump had been previously recalled because of an impeller issue. At that time, the same thing would happen. Hesitation in acceleration. After the fuel pump was replaced (done early 2025 on my vehicle), that symptom was better but in the last few months, it has returned and is increasing in frequency. It happened today as I was driving 9/22/2026 but it was not the first time. It has been ongoing for months now so I decided to finally report it. I feel that this is related to previous the federal safety agency recall campaign ID number 23V858000

By August 1, 2026, the check-engine light was on in my 2019 Honda Odyssey. I reported that the light was steady and the van was running normally, with no noticeable drivability problems. On August 31, 2026, at 141,126 miles, an authorized Honda dealer recorded DTC P0430, performed an air/fuel test, documented that the fuel injectors failed, and recommended replacing them. The dealer noted that failed injectors can cause P0430. The injector-specific parts-and-labor estimate is $1,849.06. No injector repair or post-repair test is documented yet. There was no crash, fire, injury, fatality, or police report. Honda Service Bulletin 21-010 provides a 10-year/150,000-mile injector warranty extension for certain 2018-2019 Odysseys. For P0430, it directs an air/fuel test and injector replacement if the test fails. Honda says this vehicle's VIN is ineligible despite the dealer's matching diagnostic pathway and offered 50% goodwill. This bulletin is a warranty extension, not a recall. I ask the federal safety agency to examine whether the eligible VIN population adequately captures 2019 Odysseys with this documented failure pattern. The attached evidence summary identifies 27 public the federal safety agency complaints that report injector or matching-code concerns together with VIN-based coverage exclusion; those are owner allegations, not confirmed failure rates. Some other owners allege hesitation, power loss, or limp mode, but I have not experienced those symptoms. I am concerned that continued injector deterioration could create a future drivability or loss-of-power risk. Please compare Honda's production, warranty, goodwill, dealer-test, and failure-analysis data for included and excluded vehicles. The dealer findings and evidence summary are attached.

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

Failed Component: Direct Fuel Injector Set. The components are currently on the vehicle and are available for inspection upon request. Safety Risk: The failing fuel injectors create a severe engine air/fuel imbalance, which causes engine hesitation, engine stumbling during acceleration, and unpredictable power loss. This puts my family at high risk of a collision, particularly when merging onto highways, crossing busy intersections, or accelerating from a stop. Furthermore, dumping unburnt fuel into the exhaust risks overheating the catalytic converter, creating a potential fire hazard. Dealer Confirmation: Yes. The problem was confirmed by AutoNation Honda 365 in Memphis, TN, on [XXX] (Mileage: 83,452). Manufacturer Inspection: The vehicle was inspected by factory-trained technicians at an authorized Honda dealership. A case was opened with Honda Corporate, but they refused to cover the repair, stating my specific VIN batch was excluded from their warranty extension, despite suffering the exact same failure. Warning Lamps & Symptoms: An "Emissions System Problem" warning and the Check Engine Light illuminated on [XXX]. Incident Description & Cause: Honda is fully aware of this dangerous defect. They issued Service Bulletin 21-010, acknowledging that "debris from the high-pressure pump or the fuel injector machining process can cause internal wear or clogging" in 2018-2019 Odysseys. Following the TSB 21-010 protocol, the dealer pulled code P219A and performed a "Cylinder AF Test." My vehicle failed the test (Cylinder 3 running rich). The Honda technician’s official notes state: "Fail air fuel test need injector set internal failure." Honda extended the warranty to 10 years/150,000 miles for this known manufacturing defect, yet they are arbitrarily excluding my 2019 Odyssey, which has the exact identical internal failure documented by their own dealer. Honda's refusal to issue a full recall leaves all affected drivers at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

Since purchasing the van, have reported intermittent hesitation to dealerships. Never duplicated at dealership. Eventually, fuel pump replaced under recall. Still had intermittent issues. On June 11,2026, while on the highway, van had slight hesitation and codes started going on dashboard. Got off the highway and the van limped into a nearby Home Depot parking lot. Had it towed to Hill Country Honda where they diagnosed a bad MAP sensor. When told it was ready for pick up, informed that the wiring harness was pinched. The technician stated that he had straightened the wiring and when I inquired about it, told that particular wire had to be cut out and replaced. Informed that I would likely have further issues with van and recommendation was to replace the whole wiring harness. I asked how it was pinched and told that it was probably done at assembly point and not noticed since it was under other components. I called Honda Cares as recommended to see if they could do anything for the van but Honda said the van was not under warranty so no assistance was provided. The van has 74,000 miles and always maintained by dealerships. Honda Cares said outside influence was the reason nothing could be offered. I believe that Honda is responsible for this situation and I have known 3 different 2019 owners who shared hesitation issues as new owners. Rear speakers are playing very low and told it might also be affected by wiring harness but I don’t think I should spend $4500.00+ to fix this problem.

My 2019 Honda Odyssey stalled at a red light, then had an extended crank/no-start. It later hesitated and almost stalled while driving around 40 mph, and stalled again when I got home. The dash showed Emissions System Problem along with VSA, EPS, Brake System, Brake Hold, Hill Start Assist, and Road Departure warnings. Please check open recalls, especially the fuel pump recall, scan all stored and pending codes, test battery and alternator, and check fuel pressure and fuel pressure leak-down.

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.

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.
