Other Fuel System Problems of Honda Odyssey - part 1

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 NHTSA recall campaign id number 23v858000.

On September 14, 2026, my 2020 Honda Odyssey experienced a sudden, severe low-pressure fuel pump failure while idling/parked. The engine began running extremely rough, surging repeatedly between 300 rpm and 1,000 rpm, knocking, and stalling. I was parked at the time, preventing a severe accident. Upon trying to restart, the vehicle turned over multiple times and would only catch when depressing the accelerator pedal, accompanied by cylinder knocking and an engine thermal spike. The vehicle was towed to an independent repair facility (tuffy auto service). The diagnostic scan confirmed dtc p0087 (fuel rail/system pressure - too low). A mechanical gauge test showed the low-side fuel pressure dropped to 10 psi (far below the standard operating pressure of 50–60 psi). The shop verified that the in-tank low-pressure fuel pump assembly failed internally and requires complete replacement. This failure, symptom pattern, diagnostic code (p0087), and component match the exact defect profile in NHTSA recall 23v-858 (denso low-pressure fuel pump impeller failure). However, when checking my VIN, american Honda claims this specific vehicle is excluded from the recall range. American Honda consumer relations subsequently refused goodwill assistance due to non-dealer service history and vehicle resale status. This creates a severe safety hazard. A vehicle experiencing a sudden drop to 10 psi fuel pressure while driving in traffic will lose motive power, stall unexpectedly, and disable power steering and braking assist. I am submitting this report because american Honda has failed to include all affected production batches in recall 23v-858. I request NHTSA expand recall 23v-858 to include out-of-range 2020 Honda Odyssey vins exhibiting identical low-side fuel pump failures.

Faulty fuel injectors. Causes code p0219a.

The fuel injectors are failing which is causing a safety concern with regards to moving the vehicle. There was a warranty extension on these items that does not go far enough to remedy the issue. The components have been inspected and confirmed by the burns Honda dealership in marlton, NJ. Because the vehicle does not consistently accelerate, it is a safety risk.

1. Component failed: the low-pressure fuel pump failed. The vehicle is currently sitting at my residence and is available for inspection upon request. 2. Safety risk: the vehicle stalled completely while driving, causing an immediate loss of propulsion on a public road, creating a severe collision risk. 3. Confirmation: the problem has been pulled and confirmed by an independent service center (autozone diagnostic scan tool), which pulled a code to replace the fuel pump. 4. Inspection: the component has not yet been inspected by the manufacturer, police, or insurance representatives, as the manufacturer is currently refusing to authorize an inspection due to a salvage title. 5. Warning lamps/symptoms: immediately prior to the stall, a complete cascade of warning lights appeared on the dashboard simultaneously, and the vehicle sputtered aggressively upon attempting to crank and restart. Assessment: this is the identical, textbook physical failure condition of NHTSA campaign 23v-858 regarding defective factory-installed denso fuel pumps in 2018 Honda Odysseys. American Honda corporate is using an automated salvage title database filter as a pretext to deny mandatory federal safety recall remedies on a vehicle with zero structural fuel system damage.

Emissions system code popping up. Car smells of fasoline.

The vehicle suffered an auto idle stop failure at a red light. The engine shut down normally, but failed to automatically restart when the brake was released. There were no dashboard warning lights, and I was forced to manually shift the vehicle into park to restart the engine in active traffic.

There is a very strong exhaust smell in the cabin. This occurs under the flow and recirculate hvac options and is not improved by changing the engine and cabin air filters.

My van will stall at red-lights. It started three weeks ago. The car is a year and a half old. The auto- idle stop system is activated. We stop at a red light. Car stops. When we go to start car dings and thankfully has started 3 times. This time, the car made a ding and did not re-start. I was stuck at a now green light and couldn't move. The dash flashed hit the brake to re-start. I did numerous times. I couldn't get the car to switch to park or drive. I tried switching the car on and off and couldn't get it restarted. I was disabled for about 2 minutes before it kicked back on. My kids were in the car and this scared me.

The problem only happens after driving for more than 30 minutes. When I stop at a light, the engine starts shaking and stalls. The starter seems cranking normally, but it takes about 3 attempts and about 40 seconds to restart. One day, the engine stopped while I was driving. There is no check engine light. I took it to Honda dealer. But they keep saying they cannot replicate the problem. It is so dangerous to drive this car.

What component or system failed or malfunctioned, and is it available for inspection upon request? - fuel injectors - they can be inspected in needed how was your safety or the safety of others put at risk? - this issue can cause issues with the engine and ultimately make the vehicle unsafe to operate. Has the problem been reproduced or confirmed by a dealer or independent service center? has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? this is a known issue with Honda vehicles including the Odyssey for 2019. There is a service bulletin 21-010 that mentioned the issue but only covers some vins but this is an issue with other vins that the dealer refuses to cover. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? a check engine light will come on.

5 times since July 2026 the vehicle 2025 Honda Odyssey fills with the smell of gas. The smell fills the entire garage. After the 4th incident, it was brought to the dealership on 8/18/2026, however they were unable to reproduce the issue smell. They stated the evap system was function and at the time there were no obvious leaks. Despite it being a known issue, there are no recall or repairs per the dealership. They stated that Honda is apparently aware and are "investigating. " the smell recurred today and was immediately brought to the dealership since the problems was not reproduced when previously in their possession. It was noted by multiple staff member but since there is no known fix, there was nothing the dealership could do. They are aware of several other Honda Odysseys with this issue in the same area. I was instructed not to park the vehicle in the garage which makes me concerned for mine and my family's safety. The smell can be very overwhelming and makes me lightheaded.

My car, 2025 Honda Odyssey intermittently develops a raw gasoline odor inside the passenger compartment, particularly when traveling over bumps/rough pavement. Honda dealer inspected the vehicle and could not identify a leak or reproduce the problem.

While at a stop light on a major road, the vehicles auto start stop engaged. Upon the light turning green, I released the brake and vehicle failed to restart. The vehicle put itself into park and flashed a warning message "problem detected. . . . . " . I pressed the start button, and at first the vehicle failed to start, making a clicking sound, consistent with a dead battery or starter. I had to press the start button 4 times before the vehicle restarted and I could proceed. I was extremely concerned as I had my wife and three kids in the car, unable to move forward on a major roadway. I have an appointment at the dealer for this Friday.

When driving the vehicle it always has a lag in acceleration when pressing on the gas pedal. There are numerous times I can press the gas pedal and the car will not move. I've taken back to the dealer to see what their service department says.

This vehicle is actively immobilized on private residential property with its central adas safety networks and advanced driver-assist networks completely crashed and offline (dtc u3000-49) and active short-to-ground circuit failures (dtc b2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign NHTSA recall 26-v-423 (rearview camera failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the power tailgate control unit and heavy corrosion on the wiring connector under a previous repair order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, american Honda corporate case management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.

Gasoline fuel vapors enter the passenger cabin of my 2026 Honda Odyssey while driving. The problem began xxx, the day after a dealer oil change, and has recurred repeatedly, growing stronger each time. It is worst in high ambient heat (100 to 116 f), with the fuel tank above half full, and after extended idling or stop-and-go driving on a heat-soaked engine. It initially occurred only after idling but now also fills the cabin at cruising speed. No warning lights or messages precede it. On xxx in about 116 f heat, the cabin filled with gasoline vapor with my two children (ages [xxx] and [xxx]) aboard. Onset was immediate: nausea, lightheadedness, and sore throat. I had to shut off the a/c and open the windows in extreme heat to reduce exposure, and the children had to be taken home in a different vehicle. Poison control was contacted the same day, opened case files for all three of us, and assessed the symptoms as consistent with short-term gasoline vapor exposure. A pediatric follow-up is scheduled. The dealer has confirmed the problem. Repair order xxx (tempe Honda, xxx 14,032 miles) states the advisor and tech did confirm smell coming from vehicle, and that the issue is currently under investigation by ahm, with no work done. An earlier dealer inspection onxxx found nothing. American Honda has an open corporate case, and no repair path has been provided to date. In-cabin tvoc air readings of about 2. 0 mg/m3, peaking at 6. 0 mg/m3, were captured on video. The vehicle is available for inspection, and repair orders, videos, and manufacturer correspondence are available on request. The vehicle is no longer driven with children aboard. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2026 Honda Odyssey: strong exhaust/fuel odor in cabin causing dizziness and nausea I am submitting this complaint to report a potential safety issue involving a vehicle that is less than one year old. Beginning this past weekend, the vehicle suddenly began filling the passenger cabin with a strong exhaust-like odor during normal operation. The odor is severe enough that multiple occupants have experienced symptoms such as dizziness and nausea after spending approximately 10 minutes inside the vehicle. I visited my local Honda dealership to report the issue and seek assistance. According to the representatives I spoke with, Honda believes this is a known and widespread issue affecting multiple makes and models and that it is allegedly related to recent changes in gasoline formulation. I was further informed that Honda is aware of the issue, that engineering teams are working on a solution, and that there is currently no corrective action available to consumers. Honda also stated that, despite the odor, the condition does not involve toxic fumes and is only an odor concern. I am not ready to accept that explanation without further investigation. At this time: the condition began suddenly and without warning. The odor is strong and persistent. Occupants have experienced dizziness and nausea while riding in the vehicle. Honda has not identified a repair or mitigation. Honda has indicated that this may be a broader issue rather than an isolated vehicle defect. I am requesting that NHTSA review this matter to determine whether similar complaints have been reported and whether this condition warrants further investigation as a potential safety defect. I have also requested that Honda provide written documentation supporting its statements regarding: the alleged fuel-formulation cause of the issue. The assertion that occupants are not being exposed to harmful fumes. Any technical bulletins, engineering analyses, or communications related to this condition.

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 NHTSA to examine whether the eligible VIN population adequately captures 2019 Odysseys with this documented failure pattern. The attached evidence summary identifies 27 public NHTSA 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.

?while driving my 2019 Honda Odyssey at highway speeds on the 60 freeway, the vehicle experienced a sudden and total engine failure/stall without prior warning. I had all my kids in the car as well. Chp advised to call Honda the sudden stalling resulted in an immediate loss of engine power, creating an unsafe scenario on a high-speed freeway. I was forced to navigate the vehicle across traffic lanes to pull over onto the shoulder safely.

My vehicle has experienced repeated unexpected engine shutdown/no-start events, creating a significant safety hazard. The engine has unexpectedly shut off or failed to restart while stopped in traffic and while entering traffic, resulting in a sudden loss of propulsion. On one occasion, the vehicle would not restart for approximately one minute. The vehicle was inspected by an authorized Honda dealership, and the starter was replaced under warranty in July 2025. The repair did not correct the problem. Since that repair, the same failure has occurred multiple additional times. The issue has now occurred at least six times over approximately one year. Because the condition is intermittent, the dealership has not permanently identified the root cause. The vehicle is currently being returned to the dealership for further diagnosis, and I have requested that the matter be escalated to Honda technical assistance (tech line) and Honda engineering. This defect creates a serious safety concern because the vehicle can unexpectedly lose power while in or entering traffic, increasing the risk of a collision. There were no consistent warning lights or messages before the failures, and the condition occurs intermittently without warning. The vehicle remains available for inspection.

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.

Power loss when idle; it fails to restart normally, and then the car stalls for several minutes. It happens frequently despite the van being less than 2 years old (at least 3x weekly).

June 2026, I was driving my 2019 Honda Odyssey ex-l on a family trip to florida when the dashboard lit up like a christmas tree and the car went into neutral. We were on florida road a1a, close to daytona beach. My wife and I had to push the car off the side of the road and call a tow truck company. This occurred on a Friday night. The only place I was able to take the vehicle for repair was the nearest dealership. I told them what happened. The service writer tells me the issue is the fuel pump and high pressure fuel pump. The cost was $2,800. When I told them I was on vacation and this issue should've been resolved back in 2021 with the recall they told me nothing could be done. I had the recall work completed in 2021 with 12,000 miles on the van. The fuel pump & high pressure fuel pump problem occurred in June 2026 with 51,000 miles on the van.

Codes are being detected that is associated with service bulletin 21-010 but my VIN # was not part of the service bulletin and I strongly believe it should be part of the service bulletin.

The van suddenly died, thankfully on a lower traffic neighborhood road. It would not start and we had it towed to the dealership. Upon troubleshooting, the "low pressure" fuel pump was bad. This resulted in a $1,500 repair for a vehicle only 5 years old. Thankfully this did not happen on the highway, but this is dangerous and should not happen on a car only 5 years old and well maintained.

Fuel pump injector needs to be replaced at approximately 68,000 miles. Honda issued an extended warranty on fuel pump injectors for 2018-2019 models but refuses to cover replace it. Check engine light came on due to injector failure. This poses an extreme safety risk.

Vehicle shuts off completely when stopping at a light or sign. It does restart but you don't know it until you need to go. It is a safety concern!.

My vehicle is having issues with the fuel engagement system. This is a recall on 2016 Honda Odyssey but when I type in my VIN it says my vehicle is not affected. My vehicle is affected and would like it looked at under this recall.

Our 2025 Honda Odyssey has now experienced three failures for the same defect, including two starter replacements within two weeks, without resolution. The most recent repair, overseen by Honda tech line, happened after the vehicle died June 2 while in traffic and it had to be towed to the local dealership using our insurance. On June 15 the vehicle died again, just five days after I picked it up with assurance that this issue was resolved, and it is was towed back to the dealership by Honda towing. The repeated part swaps, without root?cause diagnosis, clearly have not resolved the issue and have left us with a one?year?old vehicle that is unreliable and unsafe to operate. My minivan has failed in the middle lane of a major road while idling at a stoplight twice and in a parking lot once. All incidents were within 15 minutes of driving and 5 miles from my home. This is a critical safety defect and the repeated failures place this vehicle within the criteria that may qualify under kentucky’s lemon law. We have not made that claim yet, but we are formally documenting the repair history and escalation. ———- -starter failed and was replaced twice. This could have something to do with the auto start/idle system. -our one year old van is unsafe and unreliable. It died near a major intersection while idling at a stop light. I was in the middle lane and it wouldn’t restart for 5 minutes. I was very afraid my children and I would be rear ended. -the dealership has confirmed the problem, but they not been able to recreate the scenario despite it happening on 3 separate occasions. -Honda tech line has been directing the local dealer what to do after the first starter replacement failed. I filed a claim with american Honda. -no warning lights/lamps prior to failures.

The high pressure fuel pump has failed on this vehicle. This is a known problem for vehicles between 2017 and 2020 and has not been adequately addressed by the corporation.

When picking my child up from school, upon departure, the front end of the vehicle began violently shaking and sounding as if it wanted to shut down, simultaneously, a number of system failure warnings displayed on the dash. I was able to get the vehicle into a parking spot and turn it off. It would not restart. I called a tow truck and had it towed to a local garage as it was not safe to drive even if it did start. Upon the local mechanic pulling codes, they pulled the code p0087 indicating a failure of the fuel system, gasoline: delivery: fuel pump. This incident put myself, my 3 children in the vehicle as well as other pedestrian children and adult pedestrians at great risk, because if I had lost control and not been able to park safely, the outcome may have been extremely different. The problem has been confirmed by local mechanic and is scheduled with the dealer in 5 days. There were no prior warnings or indications of the failure. Honda issued a recall in 2021 then closed it. It was later expanded by NHTSA in 2024. Then again closed. We never received notification of the recall either time. Recall numbers follow: 21v-21520v-314 expanded recall: 23v-858/Honda TSB 24-022 both, im told are closed, which is unfathomable to me given the significant and known dangers attributed to this issue.

Fuel injector failure in exact manner described in TSB 21-010 and code p219a. The emissions error is exactly matching TSB 21-010. Honda states that the VIN number is outside of scope and is requesting an out of pocket repair. According to many online complaints, the VIN numbers need to be expanded.
