2019 Honda Pilot: misfire or rough idle

Filed Oct 19, 2026 · Fuel system, Transmission · GA

Took Pilot to Reilly's for FREE diagnostic reading. Showed misfires in cylinders 4 & 5 & random misfires. Then took to Son's Honda and PAID for the same diagnostic readings which were the same. The Pilot drives in a "limp mode" due to the issue. This issue is a known Honda issue for this year and make model. They have granted some Pilots an extended warranty to resolve the known issues. They say mine doesn't qualify even though it is the exact same issue. Defects with their fuel injector system. A secondary issue is the Transmission. We were traveling 2 hours away on the highway when we got a warning to pull over. Our Transmission fluid was too hot. This is another issue I have found to be a common problem with the 2019 Honda Pilot's and their redesign transmission system.

The motor is misfiring on cylinder 5 due to faulty engine components. The vehicle is available for inspection on request. My safety and children’s are at risk as the cabin fills up with raw fuel fumes and makes you feel dizzy. It is also a huge safety risk that I have a failed motor and not one sensor or computer component came up to warn on the dashboard(aka engine light). The problem was brought to two different Honda dealers and the second one confirmed all this is true and faulty due to the manufacturers. No it hasn’t been inspected because we can’t get corporate to take us seriously or call us back in the right department. There were no warning lights on and it first appeared since the injectors were replaced.

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 federal safety agency investigate Honda’s arbitrary exclusion of affected VINs for this acknowledged safety defect.

I am submitting this complaint to report a catastrophic engine failure in my 2019 Honda Pilot Elite that is consistent with the defect described in the federal safety agency Safety Recall 23V‑751, and to request that my vehicle be included in the recall or that the scope of the recall be expanded. My vehicle, manufactured in July 2018, experienced a sudden onset of engine knocking accompanied by a flashing check engine light and a P0301 (cylinder 1 misfire) diagnostic code while driving at highway speeds. After safely returning home and attempting reasonable repairs, I brought the vehicle to a Honda dealership for inspection. The technician determined that: •The cylinder #1 connecting rod bearing had spun •There was extensive internal engine damage •Metal shavings were present in the oil pan •The engine required replacement of the short block assembly The total cost of repair was $9,784.94. This failure mode is identical to the defect described in Recall 23V‑751, which attributes rod bearing failure to manufacturing issues with the crankshaft. Despite this, my VIN is not currently included in the recall. Key concerns: •My vehicle falls within the same production timeframe as affected vehicles •The failure mode is identical to the recalled defect •The failure occurred under normal driving conditions •The vehicle was properly maintained and not abused This raises serious concerns that the defect extends beyond the currently defined recall population.I respectfully request that the federal safety agency: 1.Investigate this incident as part of the ongoing review of Honda 3.5L V6 engine failures 2.Determine whether Recall 23V‑751 should be expanded to include additional vehicles 3.Consider my vehicle for inclusion in the recall due to identical failure characteristics This issue represents a significant safety concern, as sudden engine failure at highway speeds could lead to loss of control or increased risk of collision. Supporting documentation is attached.

I got in my vehicle about a month ago to a lot of blinking lights. I immediately took my vehicle to Davenport Honda in Rocky Mount, NC, who stated I had a misfire and it would be over $1000 to fix the problem. Approximately a month later, a few more blinking lights came on. It was the lane departure, automatic high beam and collision lights. I took my vehicle back to the dealership that stated it is an internal failure and now the entire camera will need to be replace quoting me another $1000 job. I currently have a crack in my windshield and cannot get it replace due to this internal failure. I have read several comments about this internal failure leading to believe me this should be a recall. I don't have $4000 to $5000 to put into a vehicle every 2 to 3 months.

Said 2019 Honda Pilot, maintained per Honda recommended maintenance schedule, experienced engine knock and internal damage at 100k miles. Investigation by Honda Certified Maintenance (dealership) identified a misfire diagnostic code for cylinder #2, and observed visible metallic debris in the engine oil indicative of bearing failure. Honda Certified Maintenance suggested internal engine damage and recommended engine/motor replacement. This is premature failure of 2019 Honda Pilot engine, presumably "not included" in the "affected VIN" population of Honda Service Bulletin #24-001.

My car has a surge and hiccup. Upon the test drive the mechanic said it feels like it’s misfiring. Several mechanics have said this could be due to the fuel pump. The fuel pump is on a safety recall, however Honda has been refusing to fix it for about a year now. Due to the hesitation, when driving my car could stall any moment, which will increase the risk of a crash or injury.

I have a 2019 Honda Pilot (VIN [XXX] ), little over 70,000 miles on it. In early December 2023, I started having problems with screening flashing in cycles every warning and failure message for the vehicle. I get a cylinder 4 misfire on my person code reader. Honda Metro in Indian Trail NC tells me this is fuel injectors, they are on national backorder with no guaranteed delivery AND it will cost me over $1200 to fix there. I asked if it was warrantied or recalled and was told no. Researching I found that the 2014-2018 fuel injectors were recalled. Also, found the 2014 -2020 were same injectors so not sure why the 2019 - 2020 are not covered by same recall.

Experiencing what I believe to be a low idle misfire around the 1200 to 2000 rpm’s. I don’t know whether this will lead to an engine failure at a crucial time in traffic. I have 50k miles and this has been reoccurring since 35k miles. Blogs has suggested that this is a common problem with this model.

The car is equipped with a stop-start system that is supposed to shut off the engine when you stop (eg at a red light) and restart almost instantly when you lift the foot off the brake. The restart feature fails somewhat regularly, maybe about 5% of the time. It has happened for many years, and with increasing frequency as the car is getting older. Sometimes the restart has trouble, the car misfires a moment, but then the engine restarts, sometimes a bunch of unrelated warnings sound when this happens, the car reporting that the collision avoidance systems are now offline or similar. Sometimes the engine completely stalls and does not come back online at all; when this happens, getting it restarted generally means putting it in park, turning the car completely off, then starting it again, a process that takes 10-15 seconds. When this happens at an isolated stop sign it is annoying; it has also happened on a highway exit ramp with traffic going around our disabled vehicle. Various Honda dealers have inspected and maintained the vehicle, and none have detected anything wrong to explain this behavior. The problem is intermittent and thus hard to reproduce on demand.
