Other Fuel System Problems of Honda Pilot - part 1

I recently purchased this car from a Nissan dealership a week after we purchased it the emissions system problem light came on took it back they replaced a catalytic converter it was ok for a couple weeks and all of a sudden it showed up again my VIN doesn’t show any open recalls but I have a feeling this is a part of the recall that affects the certain years of affected vehicles.

My 2019 Honda Pilot ex awd (VIN [xxx]) with approximately 80,000 miles developed a check engine light along with dashboard messages indicating an emissions system problem and awd system problem. The vehicle continued to drive normally, but the warnings repeatedly returned. Diagnostic code p0172 (system too rich, bank 1) was present. The vehicle was inspected by an authorized Honda dealer on xxx which diagnosed failed fuel injectors and recommended replacement of the injector assembly at a cost of approximately $1,689. The failed components and dealer records are available for inspection upon request. While the vehicle has not experienced a loss of propulsion, I am concerned that a fuel injector defect could lead to engine performance issues, increased emissions, reduced reliability, or unsafe operating conditions if the condition worsens while driving. Honda has previously acknowledged fuel injector issues on certain 2017-2019 Honda Pilot vehicles and issued a warranty extension covering fuel injector repairs for eligible vins. However, despite a dealer diagnosis of failed fuel injectors, I was informed that my VIN is not covered by the existing warranty extension. The vehicle has been inspected and the injector failure has been confirmed by a Honda dealership. Prior to diagnosis, the only symptoms were the check engine light and the emissions system problem and awd system problem warning messages. These warnings first appeared at approximately 80,000 miles. I am submitting this complaint because the failure appears similar to fuel injector issues already recognized by Honda, yet my vehicle is excluded from the existing warranty extension coverage. I believe NHTSA should review whether additional 2019 Honda Pilot vehicles outside the currently covered VIN population are experiencing similar fuel injector failures. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am having transmission issues with my 2019 Honda Pilot. There is an extended warranty service bulletin out, Honda USA claims my vehicle does not fall under that extended warranty based on the VIN. I am experiencing all of the symptoms of the fuel injector issues that they report in the bulletin. I am unable to get anybody at Honda to help me.

My vehicle's fuel injectors failed, triggering a check engine light with code p0430. This matches a known manufacturing defect described in Honda's technical service bulletin 20-100, which states injectors on affected vehicles may not have been manufactured to proper specifications, causing internal wear or clogging. The problem was confirmed and repaired by an authorized Honda dealership. The manufacturer extended the warranty for this defect to 10 years from original purchase or 150,000 miles, whichever comes first, due to the scope of the issue. My vehicle fell outside that window by approximately 15,000 miles despite showing the identical, factory-acknowledged defect. I paid out of pocket for a repair the manufacturer's own documentation attributes to a manufacturing defect, not normal wear. I am filing this complaint because owners with vehicles exhibiting this same documented defect are being denied coverage based on an arbitrary mileage/date cutoff, even though the defect originates in manufacturing and symptoms (a triggered check engine light) may not appear until after that cutoff has passed. This means the extension does not protect all owners of vehicles containing the defective part, only those whose symptoms surface within an arbitrary window. There was no impact to vehicle control or immediate safety when symptoms appeared, but the underlying condition stems from a part Honda has already documented as defective.

The vehicle experienced a check engine light with code p0430 and a failed air/fuel ratio test due to defective fuel injectors leaking raw fuel into the exhaust bank. This failure completely mirrors the factory defect in Honda service bulletin a21-010 (NHTSA 10187008), which extends the fuel injector warranty to 10 years/150,000 miles. A certified Honda dealer verified the exact codes and components but explicitly denied the mandatory corporate warranty extension, attempting to charge $1,804. 51 out-of-pocket and ignoring subsequent communication. Unburned raw fuel dumping into the catalytic converter presents a progressive engine failure and exhaust safety hazard.

A critical failure in the direct fuel injection system caused severe engine misfiring, sudden loss of drive power, and a cascade failure that disabled safety systems during vehicle operation. Diagnostic scan confirmed dtcs p0172 (fuel system rich) and p0301 (cylinder 1 misfire). In response to the misfire, the vehicle's computer automatically disabled the electronic power steering (eps), vehicle stability assist (vsa), and sh-awd systems (diagnostic codes u0401-68, u0416-68). This is a known manufacturing defect involving internal injector wear and high-pressure fuel pump debris (detailed in Honda TSB 20-100). The sudden loss of engine responsiveness paired with the simultaneous disengagement of traction and steering assists while driving creates an immediate crash hazard. Because Honda currently limits this repair to a 10-year warranty extension rather than a mandatory safety recall, vehicles with low mileage are experiencing sudden safety-assist shutdowns on the road without manufacturer remedy.

Vehicle stalled twice within a week. All lights on dash showed up. P0087 code. Honda dealer confirmed low fuel pressure pump needed to be replaced. It was happened on 8/13 and again on 8/22/26. Lucky, I was exiting the fwy. Almost lost control of steering wheel.

Have a 2019 Honda Pilot - fuel injector failure/catalytic converter at 115,000 miles. Estimated cost over $2,200. Known manufacturing defect: Honda service bulletins 20-100, 21-002, 22-002 acknowledge widespread fuel injector failures in 2019 Honda Pilots caused by debris from manufacturing process. Honda extended warranty to 10 years/150,000 miles for certain vins. My VIN is excluded despite identical failures and many others complaint of the same issue. Something needs to be done to hold Honda accountable!!!!.

Tachometer is starting to surging idle. Getting a wave of errors lights and messages. It’s also a known problem on the 2019 of the same model and it has a recall. I received the same code from an auto repair shop. Service bulletin 21-010.

Auto idle stop (ais) system failed to restart engine after automatic shutdown at high elevation (~10,000 ft), following a long sustained incline. Vehicle had been driven through extreme heat (100°f+) in foothills prior to the climb, then ascended into cooler mountain air (~70°f). Coolant temperature gauge read normal (under half) at time of incident. At a stop, ais shut off the engine as designed. Engine did not start when I released the brake pedal. I have tried to turn off the car completely and start it again. Engine would not restart via the engine start/stop button afterward. Cranking was strong and fast, but engine did not catch/start. Vehicle was inoperable for approximately 5 minutes, after which it started normally with no further intervention (no jump start, no mechanical repair). After restart, auto start/stop was manually disabled for the remainder of the trip. Vehicle then completed a 1-hour drive home with no further starting or performance issues, suggesting the ais restart logic, not an unrelated mechanical or electrical fault, was the cause.

The vehicle sputtered and stalled on the highway. I was able to restart after a few minutes and then it stalled again. I was able to get it to a repair shop after stalling about 3 times on the way. The diagnostic code was for the high pressure fuel pump. This was replaced. Four weeks later the same problem occurred. This time I stalled on a major freeway. I was able to restart and get it off the freeway. It stalled so frequently that I had to call a tow. The vehicle is throwing the same diagnostic code but the shop suspects the low pressure fuel pump may be the source of the issue.

Full brake system, emissions system problem, and service system malfunctioning, out of the blue. Factory reset and system updated performed with no improvement.

Left home driving 5 min down the road the car suddenly started hiccuping as to power I almost wrecked it recovered but started again …was a prime example of that fuel pump issue …I turned around drove home barely made it going slow …smelling a low grade sweetish burning smell…made it home checked and found this recall online of the fuel pump issue…called dealership asked to get this fixed they told me I had to get it there they would not provide a tow and the recall issue has made it unsafe to drive…the problem is their fault and now I am expected to to pay 200 to get there…they should tow and fix… they also would not cover a loaner I’m out transportation for days and this has caused all sorts of issues as I have to get to work etc….

My current 2021 Honda Pilot (purchased used may 2024) is stalling out in live traffic - the most recent on xxx creating a massive safety hazard. (in addition, the engine is making the same exact clicking noise that the 2015 Honda VIN:[xxx] made right before the engine catastrophically seized on my way to work. That 2015 Honda Pilot seized due to a defective variable cynlinder management (vcm) system. This defect was covered by a court-ordered federal class-action settlement warranty extension (alex [xxx] v. American Honda, case no. Xxx), extending coverage to 10 years/150,000 miles. While that vehicle was fully within this window - Honda of [xxx] wrongfully denied this legal warranty. ) the current 2021 Honda Pilot (purchased used) VIN: [xxx] suffers from intermittent engine stalling in live traffic. The dealership has failed to resolve this issue across three separate visits, while exploiting the emergencies. The timeline of failed repairs includes: 2/14/ the vehicle stalled in live traffic. The dealership charged me $420. 48 for diagnostics and a failed repair. 8/13/the dashboard lit up and the vehicle suffered engine failure leaving my family stranded for 9 hours waiting for Honda assist. It was brought to the Honda of new rochelle service center where they exploited this emergency to charge me an exorbitant $1,300. 00 out of pocket for unrelated work financed via sunbit loan. 9/24/2025: the vehicle stalled in live traffic for a third time. The dealership charged me an additional $572. 00 for another failed repair. They reguse to give me the ro's and the car has 29 active codes including u3006-16 (ecu power source failure), proving a severe electrical or fuel delivery hazard remains completely unresolved.

I just parked my car in my driveway and after an hour, I went back to drive but my car wont start at all. No power and cannot start . This happened twice I was in a restaurant and when I went back to my car, it wont start and no power. The first time it happened when I went to the restaurant and I towed my car to the service center and they told me it was a glitch . The 2nd time it happened they could not figure out and so they asked help from Honda tech line and recommending to do a dashboard tear down to check the wire harness on my own expense. Very frustrating .

Driving home from church Sunday June 28th downslope of a small hill smelled hot metal; wasn't sure if the odor was from us, the large truck that just passed us or environmental; sudden "pop" was heard accompanied by a "jerk" in the vehicle; loss of steering and brakes; dash was lit and showed rpm/mph/etc then battery light came on smoke billowing from engine followed quickly by complete fire from enginge; all 4 passengers eventually got out; police and fire dispatched; complete loss; traumatic to say the least; only light previous was service soon as oil life was at 15%; believe to be a known issue with 2017 Pilots rods bend and break but now warning (researched after the fire).

2019 Honda Pilot with under 60k miles, no obvious symptoms but codes p219b and p0430 coming up, multiple sites reporting common recall for fuel injector issue with these codes. Called dealer and reporting that VIN not covered even though codes/symptoms the same as other vehicles covered under recall. Estimated cost over $1000 to replace fuel injectors.

I was driving home at 4am on I-95 with my children in the car. My car has had a history of "juttering" and making a vibrational noise, but on the way home there was an issue with acceleration when using the gas pedal, and slow to gain speed. There were times when the gas pedal didn't respond to my foot depression at all, and did not accelerate. When I was almost home, many lights came on my dash including: blind spot warning, emissions systems problem, transmission problem apply parking brake when parked, stop driving when safe transmission problem see manual. The car is not driveable at this time and sitting in my driveway. I have no idea where to tow it to or what to do or how much it will cost.

Fuel started to pour from under the vehicle above the gas tank. The seal on the fuel pump was causing this when the vehicle was turned on. The fuel pump was on recall for this failure and the vehicle was towed to the Honda autonation dealership in mobile, al. While there the franchise dealership executed safety recall 21-034 on my 2019 Honda Pilot; the fuel pump. The technician then sent us a video saying the fuel pump did not fix the problem as a rodent had chewed through the fuel line near the fuel pump above the gas tank. He did not show an image of this damage nor produce evidence of rodents. During the repair, the technician mechanically damaged the high-pressure fuel line. The line subsequently continues to leak gas under pressure, creating an immediate engine fire hazard. The dealer then falsified paperwork blaming rodents to escape liability. This is evident by the crescent shaped slice through the fuel line. I have video proof showing the difference in fuel leaks from the pump and then from the sliced fuel line.

The vehicle came to a complete stop while attempting to enter the highway. As I accelerated to gain speed, and the vehicle halted down to stop, all sensor warning systems started to light up on the dashboard: adaptive cruise control, automatic emergency braking, lane departure warning, parking collision warning, lane keeping assistance -- all sensors flashing simultaneously. As our vehicle stopped, the vehicles around us in the highway had to abruptly stopped as well, causing a serious hazard, not only to myself and my family, but also the potential for a serious injury to other as well. This incident happened to us twice, and my passenger was able to record a video of the dashboard, as all the sensors were flashing and the vehicle switch to neutral on its own coming to a stop. We explained to the Honda dealership service department and after the second time, they kept the vehicle for service and it has been over (30) days since we had any update. The vehicle has been inspected by the dealership, and it is still there as parts are in back order, but there are not sure of what the real problem is. There were no previous warnings of this problem, the vehicle is a 2024 Honda Pilot elite with 30,174 miles, and still under dealer warranty. This is the 3rd Honda Pilot I ever owned and never experienced anything like this before. My biggest concern is that if they do not fix this vehicle properly or if it is defective, my life and my family's will be in danger every time we drive it, as we do not know when it will decide to stop while driving.

I am submitting this complaint regarding a fuel injector failure and emissions system malfunction in my 2019 Honda Pilot. At the time of the failure, the vehicle had approximately 94,693 miles and had been routinely maintained. On [xxx], while traveling from ohio to pennsylvania with my family, the vehicle displayed an "emission system problem" warning and illuminated the check engine light. The vehicle was diagnosed by faulkner Honda in harrisburg, pennsylvania. The dealership found dtc p0430 (catalyst system efficiency below threshold) and performed an air/fuel ratio test. According to the dealership, four of the six cylinders were running rich due to excessive fuel delivery. The dealership recommended replacement of the fuel injectors, and all six fuel injectors were replaced. The injector repair cost approximately $1,100. The dealership advised that possible causes included internal fuel injector failure or carbon buildup but could not provide a definitive explanation for the failure. Neither the dealership nor Honda could explain why my vehicle was excluded from Honda's fuel injector warranty extension despite exhibiting the same symptoms and requiring the same repair associated with that program. I was advised that the warranty extension applies only to certain vins produced during specific manufacturing periods and facilities. However, my vehicle experienced the same failure pattern, including a rich-running condition, emissions-system warning, catalyst-efficiency diagnostic code, and replacement of the fuel injectors. While researching the issue, I reviewed NHTSA complaints involving 2019 Honda Pilot vehicles. Numerous complaints describe similar fuel injector failures, emissions-system warnings, catalyst-efficiency codes, and injector replacements. Based on the number of similar complaints, the affected vehicle population may extend beyond the VIN range currently covered by Honda's warranty extension. I request that NHTSA review whether additi information redacted pursuant to the freedom of infor.

I am filing a safety complaint regarding a 2024 Honda Pilot touring with approximately 46,000 miles. The exact component or system that failed is currently unknown. My best assessment is that this may involve the electrical system, powertrain, engine control/software system, charging system, auto idle stop system, or another related vehicle control system. The vehicle is currently available for inspection upon request. The vehicle has had intermittent multiple warning lights appear on the dashboard. On June 7, 2026 around 9:00pm, while the vehicle was in drive, the vehicle shut off/lost power. This created a serious safety risk because the vehicle was being operated when the shutdown/loss-of-power event occurred. I am concerned this could happen again while driving, including at freeway speeds or while transporting a child. The problem has not yet been reproduced or confirmed by the dealer. The vehicle was taken to a Honda authorized dealership for inspection. The dealership advised that the battery tested fine and that no diagnostic trouble codes were found so far. Diagnostics are still pending, and as of this complaint, no confirmed cause, diagnosis, or repair has been provided. The vehicle has not been inspected by police or insurance representatives. American Honda motor CO. Has been contacted, and a case has been opened regarding this concern. Warning lamps/symptoms did occur before the shutdown/loss-of-power event. The vehicle had intermittent multiple warning lights on the dashboard before/around the time of the incident. The warning lights first appeared on or around June 3, 2026. The shutdown/loss-of-power event occurred on or around June 7, 2026. I am requesting that NHTSA document this safety issue involving a 2024 Honda Pilot touring shutting off/loss of power while in drive with no confirmed diagnosis or repair at this time.

I own a 2017 Honda Pilot equipped with the 9-speed automatic transmission. I am reporting what I believe may be transmission/torque-converter failure and a potential safety concern. The vehicle began experiencing shuddering, jerking, and hesitation. There is significant rpm fluctuation and harsh shifting. The problem occurs on highway speeds, accelerating or shifting lanes, 40–60 mph. During these episodes, the acceleration stalls and is accident prone. 8 months ago, I brought the vehicle to an authorized Honda dealer because of these symptoms, they couldn't get the code. 3 months ago, I went again for same issues, the dealer diagnosed a damaged air-intake hose and I paid for replacement. However, immediately driving off the lot, the original symptoms continued after the repair. I returned the vehicle to the Honda dealership because the problem persisted. The dealership has now diagnosed transmission failure and has estimated the repair at approximately $10,000. American Honda has offered approximately 60% goodwill assistance toward the repair, leaving me responsible for approximately $4,000. I am concerned because there are numerous reports involving transmission and torque-converter problems in 2017 Honda Pilots. Honda has issued technical service information concerning transmission and torque-converter conditions in this model year, including information involving the 9-speed automatic transmission. I am also aware of other NHTSA complaints involving premature 9-speed transmission and torque-converter failure in 2017 Honda Pilots. My vehicle has previously required other Honda-recognized repairs, including fuel-injector/emissions-related repairs that Honda covered. I am submitting this complaint because a transmission or torque-converter malfunction that causes hesitation, harsh or unexpected shifting, loss of acceleration, or loss of motive power can create a serious safety risk, particularly while entering or traveling on a highway or crossing traffic.

Honda Pilot would not restart after auto ideal engine stop. This issue caused all the warnings lights to come on with blinking engine light! Honda dealer was not able to resolve the issue and ended up paying $1500 even though it was a part of their service bulletin 23-009.

The fuel injectors have been diagnosed by my local dealership with all the appropriate codes referencing the following extended warranty bulletin issued by Honda for the repair of all 6 fuel injectors and related parts to be installed free of charge. Honda issued a warranty extension for the 2019 Honda Pilot fuel injectors under service bulletin 20-100. ?warranty coverage details ?expiration point: the warranty is extended to 10 years from the original date of purchase or 150,000 miles, whichever comes first. ?condition: the vehicle must display a malfunction indicator light (check engine light) with specific stored fuel-system error codes (such as p0300 through p0306, p0420, p0430, p219a, or p219b). ?how to get coverage or file a claim ?1. If your vehicle needs repair now ?take your vehicle to an authorized Honda dealership. They will scan the diagnostic trouble codes (dtcs).

While driving down a freeway, my car shuddered and my engine suddenly lost power and was put into limp mode. Mechanic determined it was the high pressure fuel pump that failed. This vehicle was part of the recall for the low pressure fuel pump that was completed. It also had to have fuel injectors replaced under Honda’s extended warranty over faulty injectors.

I am filing a safety and defect complaint regarding my 2016 Honda Pilot (3. 5l v6 engine). In Dec 2025, the "emission system problem" warning light ocationally illuminated on the dashboard. On 5/26/26. While driving, the vehicle suddenly began to shake violently and experienced a severe loss of acceleration—when I stepped on the gas pedal, the vehicle hesitated and would not speed up (loss of motive power). In June I let a certified Honda dealership scanned the vehicle and pulled diagnostic trouble codes p0430, p219a, and p219b, confirming that the fuel injectors have failed. This is a well-documented manufacturing defect explicitly detailed in Honda’s technical service bulletin TSB 20-100. The defect causes uneven fuel delivery and cylinder misfires, which poses a severe driving hazard, including sudden engine stalling, loss of motive power while driving, and acceleration hesitation in traffic. Although american Honda previously extended the warranty for this specific injector defect to 10 years or 150,000 miles, my vehicle was denied coverage by american Honda corporate customer relations solely because it has just passed the 10-year mark (the vehicle was purchased on November 30, 2015), despite having only 140,000 miles (well under the mileage limit). This is a critical safety and environmental hazard inherent to Honda's manufacturing design. An expiration of time does not make a known manufacturing flaw any less dangerous on public roads. I request NHTSA to investigate this persistent issue and upgrade the current warranty extension to a mandatory safety recall so that affected consumers are not left driving hazardous vehicles or forced to pay thousands of dollars out-of-pocket for an acknowledged factory defect.

On may 23, 2026 I was driving family and friends around san francisco, CA in my 2017 Honda Pilot (48k miles). We were driving up multiple steep hills, up to a 20% grade in some places with a full car of 7 people. The car handled it well. However, as we neared my home 25 miles away, the car started shaking and the check engine light started flashing. We searched online and the advice was to pull over immediately to prevent the car from overheating and causing permanent, expensive damage. We eventually made it home, shaken, and didn't touch the car for a couple days to let it rest. I learned that there is a warranty extension "warranty extension TSB 20-100" for what seems like this exact problem concerning the fuel injectors. The spark plugs have been replaced in the last year, which eliminates that as a potential issue. The next week, I took the car to Honda san carlos where it's been maintained most of its life. I informed them of the symptoms and that the car is eligible for this warranty extension. They tested it and found nothing. I told them that testing it in the shop or driving it around a few minutes on flat ground with one person is not going to replicate the driving conditions we encountered but they didn't seem to care and I had to pay $250 anyway. I took this to another dealership and the guy said it sounded exactly like an warranty extension TSB 20-100 issue. They tested it and also could not find anything. I called Honda corporate and they will also do nothing. This is clearly a safety issue as this problem will happen again at some point. I have a family and young children and do not want to be stuck on the freeway as a road hazard to ourselves and other drivers. Honda has clearly identified this as a problem yet they won't authorize the repair. They are waiting for this to happen again before they'll fix it, and who knows if this ticking time bomb will occur in a safe place or a dangerous one.

Fuel injector problem requiring replacement. Same code as known vehicles of same make and model under warranty extension. My VIN was not listed to qualify for extended warranty and Honda us refused any assistance in coverage.

Smells gas while driving.

Vehicle: 2019 Honda Pilot VIN: [xxx] my 2019 Honda Pilot is experiencing an "emissions system problem" accompanied by diagnostic trouble code (dtc) p219a (air-fuel ratio imbalance). This defect causes engine hesitation, rough idling, and a severe risk of sudden loss of motive power or engine stalling while driving at highway speeds, presenting a significant safety hazard to myself and other motorists. American Honda is fully aware of this manufacturing defect. They issued service bulletins 20-100 and 21-010 extending the warranty to 10 years/150,000 miles for this exact code and symptom on 2017–2019 Honda Pilots due to defective fuel injectors and faulty pcm software. However, Honda has arbitrarily excluded my specific VIN from this extension (case number case # xxx). Honda corporate has officially denied assistance, forcing me to drive a vehicle with a known fuel system defect that threatens sudden vehicle failure in traffic. I request that the NHTSA investigate Honda’s arbitrary exclusion of affected vins for this acknowledged safety defect. Thank you information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

In may 2026, the emission warning light unexpectedly illuminated on my 2016 Honda Pilot. I immediately sought an inspection, and repairs were completed on 5/9/2026. Failed component: the fuel injection system failed. Specifically, the injectors for cylinders #4 and #5. The replaced parts [are / are not] available for inspection. Safety risk: this defect caused the engine to run dangerously rich, dumping raw fuel into the exhaust. This poses two severe safety hazards: 1) sudden loss of motive power, hesitation, or stalling while driving in traffic, drastically increasing crash risk. 2) extreme overheating of the catalytic converter, creating a significant under-vehicle fire hazard. Confirmation & symptoms: the issue was confirmed by a professional service center. They pulled diagnostic code p0430 (front bank catalyst system efficiency below threshold bank 2). Following Honda’s service bulletin 20-100, the technician performed a software update and a cylinder a/f test. Cylinders #4 and #5 failed the test (running rich), requiring immediate injector replacement to make the vehicle safe to drive. Inspection by others & manufacturer awareness: the vehicle was inspected by the repairing facility. Honda is fully aware of this widespread defect, as evidenced by sb 20-100 and a related warranty extension. However, Honda chose to handle this severe defect via a limited warranty extension rather than a mandatory safety recall. My extended warranty expired in October 2025. When this known safety hazard manifested in may 2026, I was forced to pay for the repair entirely out of pocket. I urge the NHTSA to investigate this known stalling and fire hazard and compel Honda to issue a formal safety recall so consumers are not left at risk.
