Other Fuel System Problems of Honda Odyssey - part 1

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.

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.

?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.

The idle stop system frequently fails to restart the car after shutting down the engine at a stop light. In some cases the car is difficult to restart using the starter button. In other instances the car restarts and then dangerously lurches forward.

Vehicle experiencing loss of power especially on hills and when attempting to pass on highway. Experiencing difficulty starting drive from full stop. Slow ignition start. Occurs daily. Known fuel pump issue in year/make/ model, however VIN is not included in the safety recall.

On may 2nd, we drove our 2019 Honda Odyssey xl-e to church, and as soon as we pulled into the parking lot, we started to see smoke coming from our front hood. We exited the car. Within 30 seconds, the car then went into flames, and exploded and the car is now unsalvageable. When I went online, it seems like this is a common occurrence with these Honda Odysseys. There were no warming lamps, messages, or lights that would have alerted me that something this serious would occur. We have taken our care to Honda for years for regular maintenance. We don't take it to any independent shops. Strictly to Honda for years. The most recent checkup/service was performed on February 11, 2026 where they performed the following services which they had recommended. 1) oil change 2)engine coolant flush with conditioner 3)transmission fluid change: 4) wheel alignment 5)fuel tank additive, throttle body service, and injector. This is serious safety event and our family and children could have been killed in this accident. We have pictures, videos, police report, and the car has been taken to a salvage yard. We have filed a claim with state farm.

2019 Honda Odyssey purchased new and one owner. Vehicle's VIN didn't fall under Honda TSB # 21-010 despite vehicle suffered a known defect pattern so Honda denied assistance soley due to VIN exclusion. Sequence: emissions system warning, p0420, injector failure diagnosis, consequential catalyst failure after injector malfunction.

Complete shutdown of the engine while driving. No warnings - no flickering- no stumbling or misfire, just complete engine shutoff - dash and everything just turns off. Reading up on past recalls for this era of vans (mine a 2016) the 2013-2020 recall on the fuel pump sounds identical to this same thing I am experiencing. I was driving along in the city with my family in the vehicle and 2 times already while driving it has done this complete shutdown. If I wasn’t an experienced driver it would be enough for anyone to freak out and possibly cause some serious accidents. After I pull over and can try to restart the vehicle , thankfully it has restarted and allows me to continue forward. This is obviously not normal for a vehicle, or even a fuel pump.

The blind spot system was a problem when I purchased the car, it spent 15 days in service in the first 30 days of ownership to address the issues. Now, I after another light came on I discovered 9 open recalls on the vehicle that were not disclosed prior to purchase.

Multiple times of driving the vehicle as I am trying to press the gas pedal while driving it acts like it is not working and suddenly it stutters and stalls. The car will shut off and put you into to neutral while you try and pull over to the side of the road without being hit. It happens randomly and without rhyme or reason. After it shuts off codes are thrown such as brake failure, emissions failure, hill assist failure, steering failure, and lane assist failure. The car will be really hard to restart and if eventually will and then everything will disappear and go back to normal. Codes leave and car drives fine until it messes up again. First time it happened was months ago from this report, and then it happened monthly, weekly and now almost daily but only when you try and drive. Very unsafe and there’s no reason cars should stall at high speeds going down interstates!.

Our Odyssey is equipped with idle stop. Sometimes when idle stop engages, the engine won't start again afterwards. We need to turn the car off completely, and then try again. Usually it turns on after doing so. We try to always turn off the idle stop when we start up the vehicle, but sometimes forget. This hasn't led to an accident yet, but has led to some angry vehicles when we can't move when a traffic light turns green. To be clear, this was not an isolated incident, but happens somewhat regularly if idle stop isn't turned off. Honda dealers have told us they don't have any fix, and have recommended that we could purchase a third party "idlestopper".

The vehicle went into a limp mode due to programming and safety issue known by Honda. One of the six fuel injectors failed according to the fault codes at the dealer. I have reached out to Honda and they won't even acknowledge the safety issue nor are they willing to reimburse the cost of the emergency safety repair caused by the vehicle going into limp mode. They won't put anything in writing nor will they consent to any recorded calls. I have reached out to brad ortloff as well and he won't respond. What are they hiding? why did NHTSA allow Honda to get away with extending the warranty on the fuel injectors for certain Honda Odysseys rather than recalling them? what is the difference between the vehicles that were included? there are numerous vehicles that weren't included that are failing for the exact same reason. I can't get any answers from Honda. They just say they are not licensed techs. Brad ortloff won't respond. Why is NHTSA allowing Honda to put citizen's safety at risk? will someone please investigate this safety issue?.

High pressure fuel pump failed on a low mileage 2020 Honda Odyssey. Upon initial inspection the Honda mechanic reported the area around the fuel pipe was saturated with fuel.

The fuel injectors failed for the exact same reason as other vins that Honda issued an extended warranty for. The fuel injectors failed without warning and went into limp mode. The vehicle barely moved in rush hour in an unfamiliar city with very busy traffic. I reached out to Honda and they could not provide an explanation as to why the warranty wasn't extended for the fuel injectors like they were for other vins. In my opinion, Honda knows there is an issue, but has decided not to do anything about it. Hopefully, NHTSA can help with this potential safety issue. The dealer replaced the fuel injectors due them failing and the injectors are available for inspection.

I was driving to work on April 7th, 2026 and parked the vehicle at my company parking lot. Prior to parking, I noticed unusual smell and then parked the vehicle. I parked the vehicle around 8. 10 am and I got the call from my facilities manager around 8. 30-8. 40 am that my car caught on fire and by that time I noticed houston fire department extinguishing the fire. There were no check engine sign and this vehicle is a brand new vehicle when I purchased. Though there is no recall associated with my VIN #, the fire issue is similar to recalls for 2019 Honda odysey. The recall numbers are 23v-751( engine fire recall) & 20v-066 ( electrical wiring fire recall).

[incident description & manufacturer's bad faith] on April 6, 2026, an authorized Honda dealership (mcconnell Honda in montgomery, al) diagnosed my vehicle (2019 Honda Odyssey ex-l, 143,097 miles) with dtc p219a (rec replacing fuel injector set and fuel feed pipe at this time), requiring a fuel injector replacement. This exact mechanical failure is documented in Honda’s official service bulletin 21-010. The bulletin acknowledges that defective fuel injectors can cause engine misfires, loss of motive power, and engine stalling while driving. These conditions present an immediate and severe safety hazard. Honda established a 150,000-mile warranty extension limit for this defect in TSB 21-010. My vehicle has 143,097 miles and is well within this limit. However, american Honda corporation has arbitrarily refused to repair the vehicle. Furthermore, on April 21, 2026, the assigned Honda case manager left a voicemail officially denying the repair. He explicitly refused my repeated requests to provide this denial in writing. In the voicemail, he falsely stated that my vehicle at 143,000 miles is "well outside the range" for assistance, directly contradicting Honda's own written 150,000-mile bulletin. Please review the attached documents, including the official dealership diagnostic report (dtc p219a), the repair estimate, and a copy of TSB 21-010. I have also secured the audio recording of the case manager's voicemail to prove their bad faith. Honda is knowingly leaving a dangerous vehicle with a confirmed, documented fuel system defect on the road, while actively providing false information to the consumer to avoid repair costs. I strongly request the NHTSA to investigate Honda's deceptive and dangerous practice.

Our 2018 Honda Odyssey repeatedly and without warning completely loses acceleration power, creating extremely dangerous driving conditions. This occurs in two distinct situations:(1)while driving at highway speeds when attempting to change lanes or accelerate, and(2)when stopped at a stop sign or intersection and pressing the gas to merge into or turn into traffic. In both situations, pressing the accelerator results in little to no response — the vehicle will roll but fails to accelerate as needed. These failures have placed our family in multiple life-threatening situations. On interstate 285 in atlanta, georgia — one of the busiest and highest-speed highways in the country — our vehicle has failed to accelerate during lane changes on multiple occasions, nearly causing serious accidents. Most recently, within the past week, my husband was driving on I-285 when he pressed the accelerator and the vehicle had absolutely zero acceleration response. He narrowly avoided a collision. We have also experienced complete loss of acceleration when turning from a stop sign into traffic and when merging — situations where immediate acceleration is critical to safety. The vehicle lags for several seconds before any power is delivered to the wheels, leaving us dangerously exposed in oncoming traffic. All manufacturer recalls have been completed, including the fuel pump recall. The problem persists and has not been resolved by any dealer service or recall repair performed to date. We are aware that this is a known, widespread defect affecting 2018 Honda Odysseys equipped with the zf 9-speed automatic transmission. Hundreds of other owners have reported identical symptoms to NHTSA and to Honda directly. Honda has acknowledged the transmission's behavior to some owners but has stated it is "how the car is supposed to drive" — a response that is wholly unacceptable given the documented near-accidents this defect is causing. We are requesting that NHTSA open or expand its investigation.

Fuel pump issue, hard to start and low accelerate.

My car issues a emissions systems problem, upon bringing it to the dealer it was identified that the fuel injector system failed. This is a known issue with 2019 Honda Odysseys. Upon running the VIN on my vehicle, it was found it does not qualify under the extended warranty even though this is a known issue.

I am reporting american Honda’s ongoing failure to safely remedy critical safety defects and recalls on my 2018 Honda Odyssey (purchased new), resulting in severe vehicle degradation and a life-threatening traffic hazard. The vehicle has been to an authorized dealer over 21 times. Safety recall negligence & powertain damage: at 95k miles, the vehicle displayed active check engine codes p0087 (low fuel pressure), p0420, and p0430. The dealer replaced injectors, but severe fuel issues persisted. The dealer utilized stall tactics, claiming they "could not duplicate" ongoing stalling/hesitation symptoms. When the official fuel pump recall was issued, the bulletin mandated priority service for vehicles actively displaying symptoms. My vehicle met these parameters. However, when I attempted to get the recall performed at 111k and 120k miles, the dealer denied service due to part shortages, instructing me to drive the vehicle until it "completely broke down. " because Honda failed to supply recall parts to a symptomatic vehicle, I was forced to drive it a defective car for an additional 46,000 miles. A replacement pump was installed at 166k miles, but the prolonged forced operation directly caused the high pressure pump to fail and raw fuel to melt both catalytic converters. The dealer issued a $6,000 repair estimate for damage engineered entirely by Honda's recall delays. Life-threatening tcm failure: one day after a related service visit, the transmission control module suffered a catastrophic electrical failure. The engine completely shut off without warning while I was actively facing four lanes of oncoming traffic, creating an immediate, severe collision risk. Broken sliding doors: the power sliding doors failed under 12 months of ownership. Despite 7+ repair attempts, they remain broken, posing a severe structural/occupant safety hazard. Requests for trade-in intervention since 60k miles were systematically ignored.

My Odyssey began to shudder and misfire. Luckily, I was in a parking lot when it happened. It stopped running. Several attempts to restart were unsuccessful. Once when it did start, it was missing and would barely move. After about 15 minutes, I was able to get it started and get home (a little over 2 miles). I installed my code checker to find the problem. I initially had 22 codes - including p0301-p0306, p0300 and p0087. I waited a while and re-ran the test. The p0087 continued to show. I did not attempt to drive it anymore until the next day, when I took it to canady & branch (auto repair). They checked for codes and also had the p0087 code. They called and informed me of the issue and indicated that it involves the fuel pump. They also indicated that there were recalls for the Honda Odyssey for the fuel system:fuel pump. I contacted priority Honda to determine if this would be covered under a recall. I was told that the recall did not involve my Odyssey. I needed my vehicle, so I had canady & branch make the necessary repair ($874. 42 - the diagnostic was an additional $77). I spoke to Honda USA today and was informed that they do not cover 3rd party work and reiterated that my vehicle was not on the recall list. I was told that it had been on the list but was removed in March of 2024.
