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.

Would die at lights and so on, starter replaced and its started doing it again. Dies at lughts, stalls out at stops then will hesitate to start again and will throw itself forward making a clunky noise

My AIS system kicked in causing the engine to shut off. Unfortunately, the engine did not restart. I was unable to start my car or even shift it to neutral for a helpful bystander to help me push my car off of the road. I was blocking traffic on a busy road and I am very fortunate that I was not rear ended. Eventually, after about half an hour, was able to get the car restarted (even then, lots of “clicking” and hesitation with starting). I then drove the vehicle home. I took it to Honda and they made me aware today that they were unable to get the car to repeat this problem, nothing was wrong, I could pick it up and let them know if it happened again.

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

When the engine is hot, the car hesitates to start for a couple seconds. Occurs on really hot days especially after stopping and starting the engine such as after getting gas or on idle stop at a redlight. The motor starter has been replaced by Honda to a new one but the issue can re-occur as the part being replaced is the same with the same build and will likely fail again in hot conditions.

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.
