Other Fuel System Problems of Honda Pilot - part 2

Component involved: engine lubrication / cylinder head / variable valve timing (vvt) spool valve (solenoid assembly) and electrical charging system (alternator). Vehicle affected example: Honda vehicles equipped with the 3. 5l v6 (j35 engine series) with variable cylinder management (vcm), including the Honda Pilot. Description of the safety defect & failure mechanism: the rear (bank 1) variable valve timing spool valve assembly is mounted directly above the vehicle's alternator. Due to thermal cycling and material degradation, the molded rubber gasket on the upper portion of this spool valve assembly experiences premature compression set and fails, resulting in a pressurized engine oil leak. Because of the physical packaging and architecture of the j35 engine, the oil dripping from this failed gasket falls directly into the open housing of the alternator located immediately below it. The engine oil contaminates the alternator's internal brushes, slip rings, and diodes, leading to a catastrophic electrical short circuit and total failure of the charging system. Description of the safety risk: when the alternator fails due to oil contamination, the vehicle experiences an immediate drop in system voltage, resulting in a sudden and un-warned loss of electrical power while the vehicle is in motion. This triggers a cascade of safety hazards: loss of power steering assist: the sudden loss of electrical generation drops the vehicle into battery-reserve power, frequently causing the electronic power steering (eps) to shut down immediately, drastically increasing steering effort and the risk of a crash. Engine stalling: total depletion of the battery occurs rapidly without alternator output, leading to sudden engine stalling in active traffic without the ability to restart. Loss of safety systems: reduced system voltage disables critical safety components, including advanced driver assistance systems (adas), supplemental restraint systems (airbags).

On [xxx] at 106,266 miles, brandon Honda (brandon, FL) diagnosed my 2016 Honda Pilot with dtc p0219a (air/fuel ratio variation, cylinders #1 & #2). The dealer quoted $2,637. 99 to replace fuel injectors. This is a known manufacturing defect documented in Honda service bulletin a20-100 (issued 11/24/2020). Honda acknowledged that debris from the high pressure fuel pump or fuel injector machining process causes internal wear and clogging of the fuel injectors. Honda extended the warranty on this repair to 10 years / 150,000 miles from the original in-service date. My vehicle is approximately 5 months past the 10-year time limit but 44,000 miles under the 150,000-mile limit. Honda denied my goodwill warranty request solely based on the time expiration. This defect affects hundreds of 2016 Pilot owners. Forum threads on [xxx] have accumulated 280,000+ views with 75+ participants reporting the same failure. Many owners received $0 repairs under the bulletin while others — unaware of the bulletin or slightly outside the window — paid $750-$2,600+ out of pocket for a defect that is Honda's manufacturing responsibility. This issue was never issued as a full recall despite being a widespread manufacturing defect. The warranty extension is insufficient — it allows Honda to avoid accountability for vehicles just barely outside an arbitrary time window while the defect is clearly mileage-related (my vehicle is well within mileage limits). Honda should recall this defect or extend coverage for all affected vehicles regardless of the time limitation. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The malfunction indictator light came on due to diagnostic trouble code p0430 (front bank catalyst system efficiency below threshold [bank 2]) while driving. The vehicle has 64,240 miles and has had zero symptoms prior to the dtc appearing. This problem is noted in service bulletin 21-010 for Honda Pilots year 2017-2019, but my VIN was not included in the "VIN range". I am taking the vehicle in to the dealer for an inspection and diagnostic, but I believe the "VIN range" should be updated to include my vehicle.

Fuel pump recall performed. Since repair, check engine light appears every time fuel is added. Issue did not exist prior to recall service.

We have had a number of issues and several recalls associated with our 2017 Honda Pilot which has less than 78,000 miles on it. The issue I am writing about today involves the recent failure of the high-pressure fuel pump which I believe is related to the prior failure of the low-pressure fuel pump. In 2023, there was a recall of the low-pressure fuel pump for our 2017 Honda Pilot. The repair for our low-pressure fuel pump was delayed for 14 months because Honda did not have enough parts to cover all recalled vehicles. Therefore, we had to wait for over a year to get the low-pressure fuel pump replaced. Last week, our high-pressure fuel pump failed due to "internal failure" per the dealer. It is common knowledge that damage or failure of a low-pressure fuel pump can directly cause damage or failure of a high-pressure fuel pump because the high-pressure fuel pump relies on consistent, pressurized supply of fuel from the low-pressure fuel pump for lubrication and cooling. I believe the failure of the low-pressure fuel pumped coupled with the delay replacement of the low-pressure fuel caused the failure of the high-pressure fuel pump. Based on shared experiences online from other Honda Pilot owners, it seems like a lot of people are suffering similar issues. The high-pressure fuel pump is not currently under recall and, therefore, vehicle owners have to pay for the replacement of this part. I believe the failures of the high-pressure fuel pump and the connection to the failures of the recalled low-pressure fuel pumps should be investigated. Thank you.

I was driving and I was crossing a major intersection and the vehicle started loosing power and stalled in the middle of the intersection. I had to power the vehicle off and power on again and then it drove. It usually happens when my gas is under half. It has happened multiple times. This is extremely dangerous. I was told it is a fuel pump issue.

Car was being drive on the indiana road and rolled down window and smelled something burning. Then all of a sudden the transmission fail light came on and the car started to power down and we pulled over. The engine was on fire.

On April 9, 2026, my daughter came in from school and parked her Honda Pilot at about 5:10pm. At about 7:03pm, my wife and I were sitting outside and heard a loud pop, it sounded like a car backfiring. I went to investigate and saw a little smoke and a small orange glowing piece of something on the ground under the vehicle towards the front of the vehicle. I grab a fire extinguisher from my work truck and went towards the vehicle. The car was locked and I saw flames under the hood standing by the driver door looking down where the windshield wipers are. I used the extinguisher till it was empty and the flames kept getting worse. I just walked away and my wife was already calling 911. No one was hurt no damage to any exposures. My daughter did not indicate that anything was wrong with the vehicle. No lights on, no smells, everything ran fine. It had 154,000 miles on it. I do have ring video footage of the event. I did file a claim with my insurance and sent them the video footage.

It has happened on multiple occasions where I’m driving at 70mph, and my engine cuts out and I can no longer accelerate on the highway. My rpm’s drop to 0. I have to pull over until it comes back on again. It’s putting my safety, my children’s safety at risk, other drivers on the road at risk when all of the sudden my car will not accelerate. . Has not been inspected by manufacturer. No other symptoms, no lights come on.

An “emissions system problem” warning message appeared intermittently on the dashboard while driving. The warning light would sometimes turn off after restarting the vehicle, but the issue persisted in the vehicle’s stored diagnostic system. The vehicle was taken to an authorized dealer, where a diagnostic scan confirmed a p0430 code (catalyst system efficiency below threshold). The dealer identified the likely cause as failing fuel injectors and recommended replacement of the injector system. The issue was confirmed by the dealership and is reproducible through stored fault codes, even when the warning light is not actively displayed. This condition may impact engine performance, fuel mixture, and emissions system operation. In certain situations, this could lead to reduced engine performance or hesitation, which may affect the ability to safely accelerate or merge into traffic. The vehicle has been regularly maintained according to manufacturer recommendations. There were no significant warning signs prior to the initial dashboard alert other than the intermittent warning message. The failed components (fuel injectors) should be available for inspection upon request through the servicing dealership.

Upon accelerating from a stop, or at various speeds, the vehicle experiences a significant loss of motive power(pulling backwards) followed by an abrupt lunge forward. This hesitation occurs unpredictably and makes entering traffic or intersections extremely hazardous. This feels like a fuel delivery or transmission engagement failure. The last incident occurred on or around the afternoon of March 23. My vehicle has been examined at the dealership on multiple occasions for this same issue and each time I have been told that they are unable to replicate the issue and can not help me further unless they are able to replicate the issue.

While driving, the vehicle lost engine power on three separate occasions (3/6/26, 3/10/26, 3/20/26) and had to coast to a stop on the road. One of the codes that appeared was p0087; the Honda dealership replaced the fuel pump kit (part # 06161-rlv-305) due to the fuel rail pressure being too low, but the vehicle continued to stall upon replacement after being picked up from the dealership. When it was brought back to them, they could not find a problem or replicate the stalling. This is a safety risk because the car is stalling for an unknown reason and will not start back up for 10-15 minutes. This is a safety risk to the driver and others because stalling could cause an accident or fatalities if the driver is unable to safely pull over. Fuel pumps are a known problem in 2017 Pilots and this vehicle was not included in the recall (sb 24-010). I paid $1694 for the repair from the Honda dealership and the problem is still occurring. There were no warning lights prior to the failure. Honda should reimburse me for this cost, but they denied responsibility for the cost despite service bulletin 24-010. These vehicles are unsafe and should not be on the road at all.

While driving on the expressway at speeds above 60 mph and while attempting to pass another vehicle the vehicle shuts down with no acceleration. The vehicle will then after several seconds regain acceleration. Several times it has sounded like the vehicles starter engaged. This is a random occurrence and has happened approximately 10 times. There are no error codes and the dealership states that they can not recreate the issue so there is nothing wrong.

On 3/16/26 I attempted to accelerate and the vehicle experienced severe "bucking" and gear hunting hesitation before losing all drive power and stalling. Following the stall, the engine would not crank or "catch" despite multiple attempts. State police arrived as I was in an unsafe location (blind on-ramp to highway) they called their tow trucks deeming it hazardous to wait as Honda roadside assistance would not arrive for an estimated 60-90 minutes. It was brought to the local dealership. After an hour from incident to inspection at the local Honda dealership, the vehicle powered on normally of which no codes showed and the vehicle started with no issues. The manufacturer and dealer state they cannot replicate the problem and found no historical or pending diagnostic trouble codes (dtcs). Despite the lack of codes, these symptoms are a direct match for nhsta recall campaign 25v-031 (Honda recall al0) which was officially announced to address torque control failures caused by the fi-ecu software. According to Honda’s safety report, improper programming in the fuel injection unit causes the engine to stall during "sudden changes in throttle opening"—which is exactly what I experienced. As of now, my VIN has not been identified on the current recall list. This loss of power during acceleration creates an immediate safety risk of rear-end collisions and leaves the driver stranded in active traffic.

While driving multiple lights came on the dash board showing all driver assistance systems flashing. Vehicle unable to accelerate. Had to parking on the side of the highway turn off vehicle then turn back on to clear. Dealership unable to repeat, no issues found.

Vehicle: 2026 Honda Pilot – mileage 20,847 issue: engine failure, oil leaks, wheel alignment, air conditioning, major gas leaks from the engine, safety electronics alerts on front dash display are saying the vehicle is not safe to drive. History of issues: 03-11-2026: car broke down while driving in [xxx] . 03-12-2026: received call from ira Honda service and was told they needed to replace the engine. 04-04-2026: I was told the vehicle was ready to be picked up. I started driving home and found the vehicle was all over the road. I returned to ira Honda and once again was given a loaner. Also, the engine was leaking oil. 04-09-2026: ira Honda called and said one of the engine gaskets was defective and they needed to replace it. They said that now the alignment was back in spec. I was told that the 3 yr engine warranty begins anew. When I got home I looked more closely at the alignment document and saw that the alignment was still slightly out of spec. I called and was told that it was the best they could do. 04-10-2026: air conditioning not working and asked for them to fix the alignment. 04-13-2026: I again brought the vehicle in for service. But was told there were no loaners available. I arrived at 9:30am and at 1:00pm. The a/c was fixed and determined the frame was not set correctly when they replaced the engine. This was the reason the alignment was off by so much. So the alignment was fixed. 04-14-2026: leaking oil. So again, I had to return to ira Honda. No loaner was available. 04-18-2024: Saturday morning and we smelled gas in the garage. Started the car and it took about a minute to start. Asked if it was safe to drive, ira service said yes. 04-20-2026: started the vehicle up and same issue occurred. However, this time gas was leaking out. It leaked in our garage, on our driveway and all over the street. Again fixed. 04-29-2026: car again failed to start. During startup the car leaked a large amount of gas. It is still at the dealership. Information redacted pursuant to the freedom of information.

Hi, I have a 2020 Honda Pilot that showed signs of stalling. Autonation Honda thornton road checked (03/07/2026) and reported I need an injector kit replaced and sdc gdi -intake throttle body furl injector service. All warning lights were on intermittently (on all day then nothing for 2-3 days then on all day the following day. ) the vehicle vibrates and feels like it's loosing power. Honda's website stated risk as " if the fuel pump module is inoperative, the engine may not start or can stall while driving, increasing the risk of a crash or injury. " I have two small kids (18 month and 5 year old) that I commute to and from school every day. Honda's website shows the same issue for Honda Pilots 2016-2021 however, my VIN does not qualify me for the recall. Instead I received an estimate for said repairs for $3,345. 06. Please! I am asking you to intervein as it is unfair to single out some vehicle owner even though they are having the same issue as others. Thanks in advance.

What component or system failed or malfunctioned, and is it available for inspection upon request? the vehicle’s high-pressure fuel pump failed approximately one year after the low-pressure fuel pump was replaced under a manufacturer recall. The low-pressure pump had been identified as defective and replaced accordingly. Because the low-pressure pump is responsible for supplying fuel to the high-pressure pump, it is reasonable to believe the defective component may have placed abnormal stress on the high-pressure fuel pump prior to its replacement, potentially leading to premature failure. The failed high-pressure fuel pump is still in the vehicle. How was your safety or the safety of others put at risk? failure of the high-pressure fuel pump can result in a sudden loss of fuel pressure to the engine, causing hesitation, loss of power, or engine stalling while the vehicle is in operation. This created a significant safety hazard, particularly as it occurred during highway driving, where sudden loss of propulsion occurred. Has the problem been reproduced or confirmed by a dealer or independent service center? the issue was diagnosed and confirmed by a service center as a failed high-pressure fuel pump. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? the vehicle was inspected by my personal mechanic who indicated fuel pump issues and noted recall then a Honda dealer during diagnosis but recall was for previously replaced low pressure pump and not the high pressure pump the issue has yet to be repaired. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? prior to the failure, the vehicle began experiencing noticeable fuel system performance issues, including reduced engine performance loss of mpg and drivability concerns. No lamps.

Emission system problem light is on. It says that there is a problem with fuel injector. Low power when accelerating. Engine is working harder than before given low efficiency.

I am submitting this complaint regarding my 2019 Honda Pilot after experiencing a failure of the fuel rail assembly that resulted in the check engine light illuminating and required repair at my own expense. My vehicle exhibited the same symptoms and was diagnosed with the same fuel rail issue that is described in Honda’s existing recall for certain 2019 Honda Pilot vehicles. However, when I contacted Honda, I was informed that my VIN was not included within the recall population, despite my vehicle experiencing the identical failure. The fuel rail failure caused the check engine light to illuminate and required replacement of the defective fuel rail. Because my vehicle was excluded from the recall, Honda declined to cover the repair, and I was forced to pay the full cost out of pocket. I believe this demonstrates that the defect is not limited to the VIN range identified in the recall. My vehicle experienced the exact condition addressed by Honda’s recall, yet I received no assistance solely because my VIN was not included. Owners of vehicles with the same defect should not be responsible for repair costs simply because their vehicle falls outside the current recall range. I am requesting that NHTSA investigate whether the recall population should be expanded to include additional 2019 Honda Pilot vehicles affected by this same fuel rail defect and that Honda reimburse owners who have paid for repairs related to this safety issue.

I own a 2017 Honda Pilot. The vehicle has been stalling and losing power while driving. The loss of power creates a serious safety risk, especially in traffic and at highway speeds, as the vehicle hesitates and struggles to accelerate. The high-pressure fuel pump was replaced at my expense after the vehicle began stalling and losing power. Despite this repair, the problem has persisted. I am now being told by Honda that the low-pressure fuel pump also needs to be replaced. I have already paid for significant repairs, including replacement of the high-pressure fuel pump, water pump, timing belt, and related components. My vehicle’s VIN is not included in any fuel pump recall, although similar vehicles appear to have had related recalls. I did receive a warranty extension for the torque converter, but I have received no notification or warranty support regarding the low-pressure fuel pump. The stalling and loss of power place me and other drivers at risk, particularly in intersections and during highway driving. The issue has been diagnosed by a Honda dealer/service center. The failed components are available for inspection upon request. No consistent warning lamps appeared prior to failure. I am concerned this may be a broader safety defect affecting vehicles outside the current recall population.

Last year fuel pump in gas tank was fixed/recalled, fixed 2/2025, now 2/2026 the high efficiecy fuel pump in engine bay started making loud noises--no warning/codes--just loud banging noise, mechanic confirmed high efficiency fuel pump failing. Search on youtube also confirms many year/models as mine having same issue.

Fuel gage read incorrectly staing we had gas and estimated fuel for 70 miles. We stalled while driving. Several error lights came on, car would not start. After researching we saw alot of complaints about fuel guage issues so we were able to get 2 gal of gas and then make it to a gas station. Took car in for diagnostic, no known problem. ????.

On two separate occasions this vehicle has died when stopped at a traffic light. First time was in February and the second was in June, both times were in 2026. Both times had to push the off button and do a restart.

Currently showing dtc p219b (O2 sensor signal biased/stuck lean – bank 2 sensor 1) along with p0430 . For prior years thru 2019, Honda has issued service bulletins 19-072 and 20-100 covering dtcs p030x, p219a, and p219b, which may involve pcm software updates, a cylinder a/f test, and potential injector replacement. However, they have not issued bulletins for 2020. My car only has 58,000 miles.

Check engine light for fuel emissions and pulled codes. Codes included in known Honda service bulletin 20-100. My car was not included in the VIN search.

The"mil" reported "emmisions system problem" the dealer stated "diag code p219a" was the underying cause, and the reccomended solution was to "replace fuel injectors and check for pgm updates". I paid for the repairs, and took the vehichle home. After some research I discovered that these symptoms, codes, replacement parts etc. . Are all consistant with a Honda service bulletin (mc-10183514-0001) as refrenced by NHTSA id 10183514. Where Honda was extending the warentee for the fuel injectors. After reviewing the document I found that my VIN is not included in the scope of the "warentee extension" I opened case number 16127621 with american Honda motor CO. , inc. To inquire further and get a reasonable answer as to why my VIN was excluded from scope, they were responsive, but provided no explanation other than my VIN " is not included in this campaign for fuel injector concerns. Unfortunately, your vehicle is not eligible for reimbursement at this time. " I would like to have it "on record" that I have voiced concerns suspecting this is not a coinsidence, and the scope of the recall should be expanded.

After driving the vehicle for a few hours during a very cold day, as we got off an exit ramp. We then turned onto the next road in our travels and the check engine light went off and blinked. The vehicle went into limp mode. Pulled the vehicle over, turn the car off and then back on and everything worked just fine. Had an oil change already scheduled for 2 days later. Brought the vehicle in for it oil change and we told the Honda mechanic (dealership) what just happened. His response was: that is a common Honda problem. "you did what we would have told you to do. Turn the car off and then back on. When the engine compartment gets really warm when driving for long periods of time with the cold weather, something tells it to misfire and throws a check engine code. We tell people to do what you did and turn the car off and then back on". Meanwhile we had to go out of town again the following weekend. As soon as we got near our destination the same thing happened again. This time in an intersection! thankfully nobody was coming at the time of the limp mode to avoid a potential serious accident. I have put a lot of research into this and there are a lot of forums online that state this issue with no solution by Honda. I do not see how that is safe to have your car randomly throw a code and be forced to pull over immediately.

The fuel injector failed which cause safety issues such as reduced speed, failing safety issues, and the car is misfiring and not running safely. When driving the car started to misfire and was not running correctly. It then reduced speed and the safety features were disabled. Yes this issue was confirmed by ken vance Honda in eau claire WI. There was a flashing check engine light, hill start assist problem, emissions system problem, power steering system problem, trailer stability assist problem, and vehicle stability assistance problem lights that came on. This is a known safety issue with 2016 Honda Pilot as Honda America did an extended warranty to cover the expense to replace the injectors. Unfortunately, our car missed the deadline by a few months to get this covered. Since this was a known defective part from the factory this should have been taken care of by Honda as a full recall. There are many cars like this that are going to have safety issues and not realize what is happening.

I believe I have a fuel pump issue. My car has stalled on multiple occasions while trying to pull out of my driveway. There is at least a quarter tank of gas. I have had to get gas in a gas can and add it to the tank and then it would start. I now make sure I always have at least a half a tank of gas. On three separate occasions when the auto idle stop turns the car off at a light, the car does not restart when the brake is released and it slips the car into neutral (very dangerous at an intersection) there was a recall on Pilots fuel system, gasoline: delivery: fuel pump recall date 2023-12-17 recall no. 23v858000 Honda (american Honda motor CO. ) is recalling certain 2013-2023 Honda accord, civic coupe, civic sedan, civic hatchback, civic type r, cr-v, hr-v, ridgeline, odyssey, Acura ilx, mdx, mdx hybrid, rdx, rlx, tlx, 2019-2022 Honda insight, passport, 2020 Honda cr-v hybrid, 2018-2019 Honda clarity phev, fit, and 2015-2020 Honda accord hybrid, Pilot, Acura nsx vehicles. The fuel pump inside the fuel tank may fail. Hide details recall consequence fuel pump failure can cause an engine stall while driving, increasing the risk of a crash. As you can see it covers Pilots from 2015-2020, however I am having this problem with my 2021 Pilot. Please consider extending the recall to 2021 Pilots.

The vehicle started to make loud clinking sound coming from engine. Went to dealership for diagnostic and high pressure fuel pump failed. Was quote 2000$ .

Turned car on and it was making a very loud sound coming from what sounded like the engine. Very loud when accelerating or stepping on the gas. Driving at lower speed was also loud. Unknown if it was safe to drive. Took to mechanic and was told it was the high pressure fuel pump. There were no warning lights or warnings.
