2016 Honda Pilot Fuel system Problems

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.

My 2016 Honda Pilot Touring repeatedly stalls and shuts off while driving, including at lower speeds in traffic. When it happens, the engine and all electrical power shut off; the vehicle then has to be jump-started, and it will sometimes only restart after sitting for an hour or more. This is a serious safety hazard because the vehicle can lose power unexpectedly while in motion, creating a risk of a crash and of being stranded in a travel lane. The failed component is the fuel delivery system (fuel pump / fuel system pressure). The condition has been diagnosed repeatedly with trouble code P0087 (Fuel Rail/System Pressure — Too Low). It was first documented on July 18, 2025 at 144,303 miles by an independent service center, which diagnosed a failing fuel pump. On March 13, 2026 a Honda dealer again retrieved code P0087 and diagnosed a failing fuel pump. In April 2026, a second Honda dealer could not reproduce the code, replaced the fuel injectors instead, and the stalling returned within about 670 miles. In May 2026 that same dealer documented the problem as a "reoccurring issue" and now recommends replacing the in-tank fuel pump. The warning symptom prior to failure was the check-engine/malfunction-indicator lamp, which set code P0087; the stalling followed. The problem has been confirmed and reproduced by both an independent service center and a Honda dealer, and the vehicle is still owned and available for inspection upon request. No crash, fire, or injury has occurred. This stalling/loss-of-power failure mode is the same one described in NHTSA recall 23V-858, in which the in-tank fuel pump can fail and cause the engine to stall while driving. This vehicle is exhibiting exactly that failure mode but is not currently included in that recall population. I am reporting it so the agency is aware, and I request that this vehicle be considered for inclusion in recall 23V-858.

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.

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.

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.

The component that failed in both incidents was the vehicle’s wiring system, specifically wiring insulation that appears to be vulnerable to rodent damage. In the first incident, squirrels chewed through wiring connected to the fuel injector system, which triggered a check engine light and was repaired. In the second incident, squirrels again accessed the engine compartment and chewed through wiring affecting the braking system. This resulted in a sudden and unexpected loss of braking function. Yes, the damaged components should be available for inspection through the repair shop or service records, although I would need to confirm the exact location of the retained parts. Safety was significantly put at risk. During the second incident, the vehicle was occupied by multiple passengers, including minors. While approaching a red light, the driver attempted to brake and found that the brakes were not functioning properly. The driver had to shift the vehicle into park and use the emergency brake to stop, narrowly avoiding a serious collision. This created a high-risk, potentially life-threatening situation. The first incident was addressed by a mechanic after the check engine light appeared, confirming damage to the fuel injector-related wiring. The second incident was formally confirmed by a mechanic that the brake line was leaking from damage from, what they highly suspected and have seen in the past, a rodent . In the first incident, a check engine light appeared, prompting immediate attention. In the second incident, there were no warning lights, messages, or prior symptoms before the brake failure occurred.

We were on the way home from a soccer tournament in [XXX] on rt. XXX and 4 hours into our trip the car's fuel pedal stopped responding and our speed started descending rapidly. The engine light was on with the vehicles stability system, Hill assistant, emission system, power system, TSA..... All of them were lit. Scared I put hazards on and pulled over on the side of the road. I waited about 20 min and tried to start the car. It started and drove us home on side streets on speed 30-40 to [XXX] , wouldn't go faster and it was shaking while driving. It was quite terrifying and looking back I should have called 911, this was a first time ever I have been in a situation like that with my daughter. We got home at night. In the morning I called AAA to see if the battery was bad, they said no. The dashboard was cleared, no lights appeared and when I went to the Honda dealer they couldn't a identify the specific problem. They told me it could be a few things and told me to do repairs for $5000.00 not knowing if it would fix the problem. This first incident happened in summer 2025. I stopped driving the car on a highway and long distances, the dashboard lit up few more times but always went back to normal. A couple of weeks ago, when I again called AAA to check my battery, I was advised to go to AutoZone when the board lits up again. So I did today and was told it was code P0087 and had to do with the fuel pressure pump. So I went to my mechanic to diagnose the problem and they are in the process of repairing it. But after some research I found online that there has been a recall on Honda Pilots 2016-2018, but my car didn't qualify. So I called Honda manufacturing explaining my situation and warning them that the same thing happened to me and they said there was nothing they could do if my car's VIN # wasn't included. So I am writing to you to advise the traffic safety administration and suggest to expand the recall #XXX to more vehicles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.

My vehicle suffered a catastrophic failure of the exhaust and engine systems directly caused by the defective fuel injection system identified in Service Bulletin 20-100. Despite providing evidence that the failure was initiated by these defective injectors, Honda has only provided a partial, unexplained reimbursement and refuses to acknowledge the extensive "downstream" damages. Diagnostic Evidence: At the time of service, the vehicle stored the exact diagnostic trouble codes (DTCs) specified in the bulletin: Fuel/Misfire Codes: P0302, P0303, P0305, P219A Catalytic Efficiency Codes: P0420, P0430 Repairs & Financial Impact: The fueling imbalance and extreme heat caused by the faulty injectors led to: Replacement of both Catalytic Converters (directly cited as a potential result of injector failure in SB 20-100). Cylinder Head Gasket Replacement & Head Resurfacing (caused by excessive thermal stress and localized overheating from the lean/rich conditions). Fuel Injector Replacement. Dispute Details: Inadequate Reimbursement: After months of persistent hounding, American Honda issued a payment of $736. No explanation was provided, but this amount likely only covers the injectors, ignoring the thousands of dollars in consequential damage. Admission of Defect: By issuing this partial payment, Honda has formally acknowledged that my VIN was affected by the manufacturing defect described in the bulletin. Lack of Transparency: Honda has failed to provide any technical justification for how the catalytic converter and head gasket failures—which occurred simultaneously with the specific codes in the bulletin—could be considered unrelated to the admitted injector defect. Request for Action: I am requesting an investigation into Honda's failure to cover the full scope of damages caused by this known manufacturing defect. The partial payment is an admission of fault regarding the injectors, and the resulting engine and exhaust damage is a direct, documented consequence of that

Our fuel pump went out, causing us to be stranded and having to have our Honda Pilot toward 45 minutes away to the Honda dealer to have it replaced. There were no warning lights on until we were going down the highway and all of a sudden the dash warning codes were flashing like crazy. We turned our car off, then when we turned it back everything kept flashing, many warning lights at once. Honda diagnosed with Code P0098 and replaced the high pressure fuel pump. There was a recall made the week after we had ours fixed, but not for our model.

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.

We started having problems with the catalytic converter clogging so we put Heat in it and then only used 100%gas. Then we went to my daughter’s house and when we went to leave the car wouldn’t start. We could smell burning. We had it towed to our mechanic and he replaced the starter but he had a hard time getting it off because it was almost fused because of the heat. Then 3-4 days later all the check engine lights came on. We had it checked out by Christian Brothers and he had to replace all of the fuel injectors. He also had to replace the ERG valve. It all I feel was caused by the fuel injectors and was causing problems in the engine and causing the burning smell. I have read that this has been a problem on the vehicles and wanted to report it for a Recall. We love the vehicle but with the mileage only being at 143,400.

I was driving and went through an intersection when all of a sudden the car automatically shifted into Neutral and lights started flashing and stalled. The engine ceased up. I checked to see if I had oil. I did. Prior to this event on multiple occasions while driving on the HWY and trying to accelerate the engine had problems getting into gear. This vehicle has made me feel unsafe multiple times while driving and shifting out of gear and now just stalling while driving. Honda has a huge problem with the engines.

warning engine light came on. Emission control system light came on too. Honda Pilot 2016 Milage 70,662. Vehicle operating normally. Had car parts store use OBD electronic scanner and it revealed a code P0328: "Knock Sensor voltage High". Code was deleted after scan. I was told by tech at car parts store that the sensor was detecting odd electronic signals and sent info to the cars computer, which intern made the computer to display the warning lights on the dash panel. Warning lights were then off, and then a day later, the engine warning lights came on again. There are no physical or audible signs that any mechanical errors are happening, The car/engine is operating as normal. next day; made appt with Honda dealership to check system with their equipment and the warning lights did not come on , prior to the trip to the dealership. Dealership scan (Dec 23, 2025) confirms a faulty Knock Sensor w/code P0328. My internet search of this code reading, reveals possible engine damage, improper fuel distribution and possible engine failure when driving. This issue has been reported before, many times, per my internet search...why no recall? Dealership wants $1,234 to replace Knock sensor bank 1& 2. My original request to the dealership was to check my vehicle to see if it had any performance problems as noted in Honda Service Bulletin 20-100 Nov 24, 2020 problems, but their search revealed the P0328 code . I was charged $100 just for this diagnostic system search.

Honda is aware of thousands of 9 speed transmission failures. but worst of all they tell you that you failed to change trans fluid as scheduled, but there is no schedule printed in their owner's manual, nor in their vehicle service maintenance manual. the service manual only speaks to the quality of fluid required, and that it not be mixed with other brands of trans fluids. it then goes on to say "HAVE A DEALER CHECK THE FLUID LEVEL AND REPLACE IF NEEDED." I have owned cars with sealed trans that required no maintenance, which is not the case with the Honda's 9speed trans. The Honda 9 speed is a sealed unit. I am currently face with an estimated bill of $10,600 to replace my failed trans. There is a reaccuring problem with the 9 speed, that Honda should pay for. I am requesting an investigation, and a reimburstment of my total cost. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The fuel injection system routinely fails or misfires. Not only does this cause an issue with said system but it also triggers a host of other dashboard alerts. The alerts display all wheel drive problem, emission system problem, power steering problem, hill start problem, vehicle stability assist problem. This is a safety issue because the amount of alerts especially unrelated alerts is obfuscating any actual problems and making it difficult to diagnose the real issue. Investigation shows many other drivers having the same issues with this model only going away when the fuel injection system is replaced. It's also safety issue because if the fuel injection is failing then the car may shut off at a danger to the driver and the public. Given that it is known and chronic it should be a recall

Car electric system went down while driving and stopped in middle of the road. It happened sometimes before, usually when the car stops at the red light. All the warning light was turn on when that happen and it took a lot of try to restart the car. This time the car cannot turn on so I have to tow it to my mechanic. The mechanic checked everything including the alternator, battery, starter and told me that the problem is actually in the fuel pumps. I got the fuel pumps replaced and have not had the same issue since then. The mechanic said several Honda model had that issue. I contacted Honda as I see there is a recall on the same year model but Honda told me the VIN number isn't on their list, but I think the recall should cover my vehicle since the problem description and year model is matching.
