Other Fuel System Problems of Honda Odyssey - part 1

Vehicle was inspected, vehicle is leaking fuel, but it's difficult to spot, but I have to put fuel on it daily, tcs goes haywire almost caused me to crash because the tcs sensors are near the tires, and engine crank sensor issues, vehicle does not do last gear shift, and rear door stopped working.

My 2019 Honda Odyssey had an emissions code come up with obd ii sensor code of p219a which led to research revealing that the code was a result of fuel injector failure. I took my van to the dealer who revealed that based on my VIN, I am not eligible for the extended warranty issued by Honda in 2021. This has resulted in a $1900. 00 repair bill that should be covered based on history and problems. Ref: [xxx] and [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S.

Life-threatening acceleration lag: the vehicle is experiencing severe power loss during critical driving moments, for example, while entering intersections or attempting to re-accelerate into moving traffic. When I attempt to speed up, the engine fails to respond initially, leaving the vehicle stranded in the path of cross-traffic. The engine finally engages only because I am forced to floor the accelerator pedal out of necessity, which then causes the tires to squeal when power eventually returns. Intermittent starting issues: the vehicle frequently fails to start smoothly on the first attempt; a known symptom associated with the fuel pump impeller deformation described in recall 23v-858. Vcm shudder and hesitation: I am experiencing the distinct vibration and rhythmic shudder associated with the variable cylinder management system. This symptom is most prominent during deceleration or coasting; specifically, when I lift my foot off the accelerator without applying the brakes, the system triggers a noticeable shudder as it incorrectly manages cylinder engagement/deactivation. Suspected catalytic failure (codes p0420/p0430): both catalytic converters are exhibiting inefficiency codes simultaneously, which are highly atypical and occur well before the expected component lifespan. This clearly points to upstream defects. Specifically, the catalytic substrate has been poisoned by carbon and phosphorus deposits from the documented oil-burning defect and has suffered thermal damage due to the improper fuel mixtures caused by the defective high-pressure fuel pump (recall 23v-858).

The vehicle completely stalled, we believe it’s related to the engine in reference to the idol on and off mechanism. We began to drive forward and the auto on off starter caused the car to completely shut down and freeze in an intersection.

I brought my van in for service because, when stopped at a traffic light, the vehicle enters automatic shutdown as designed; however, when I release the brake, the engine does not restart. Instead of restarting automatically, the vehicle remains off, and I have had to perform a hard start because it will not crank on its own. The van is a brand-new 2025 Honda that was purchased new. After inspection, I was informed that the battery would need to be replaced. During the same visit, I also reported a vibration issue. After checking this, I was told that the vehicle needs new shocks and that the tires show wear. I was further informed that the tires will not be covered. Given the age of the vehicle and the fact that it was purchased brand new, I am concerned about the need for a battery replacement, suspension repairs, and tire wear at this stage, as well as the decision not to cover the tires.

Idle stop failure. This has occurred many times. Presents itself failure to restart upon releasing the brake. Rough restart. Sometimes have to completely turn off car and restart.

I am writing to formally report and complain about a serious safety issue I am experiencing with my Honda Odyssey related to the auto idle stop feature. While the vehicle is stopped and auto idle stop is engaged, the engine unexpectedly shuts down and, in some cases, does not restart properly when I attempt to accelerate. This has occurred after normal driving and also immediately after refueling. When the issue happens, the vehicle loses power completely for several seconds, creating a dangerous situation—especially in traffic, at intersections, or while making turns. This issue is not only inconvenient but also a significant safety concern. A delayed or failed engine restart can easily lead to accidents, particularly when quick acceleration is required. I understand that auto idle stop is designed to improve fuel efficiency, but it should never compromise vehicle safety or reliability. I am aware that other Honda Odyssey owners have reported similar problems, which suggests this may be a known or widespread issue. I would like Honda acknowledge this problem as a potential safety defect investigate whether this issue is related to the auto idle stop system, fuel system, battery, starter, or engine control software advise whether there is an official fix, software update, recall, or service bulletin addressing this issue provide guidance on how Honda plans to resolve this problem permanently please let me know the next steps to have my vehicle properly inspected and repaired. I expect Honda to take this matter seriously, as it directly affects driver and passenger safety. I look forward to your prompt response.

The emissions warning comes on and off, the Honda dealer said it's a fuel injection system issue. Noted that NHTSA has issued extended warranty for this issue on 2019 Honday Odysseys but my specific VIN is not included. Nhtsa needs to extend this issue to additional vins having this issue as Honda is not covering it.

Car doesn't start, has needed to be jumped almost 20 times in a year. Auto start stop has shut the car off in intersections.

Accelerator pedal becomes non-responsive while driving. Honda has addressed some of the affected vehicles.

Fuel injector went out while driving known problem Honda only recalled some of the vans not all.

Vehicle shuts down and will not restart. So far this has happened three times. After a long delay, took foot off gas, held brake and pushed start and would not start. On third attempt vehicle was very labored on start.

Engine turns off by itself at stop. Auto idle stop was not turned on. It also happened when I pressed the reverse button. When it turns off by itself, I have to turn it back on and put it back into gear. It happened 4 times today.

I own a 2018 Honda Odyssey elite. While driving to er for my daughter engine started making weird knocking sounds, when I stopped at a red light to turn left off the interstate Odyssey just died and began to smoke. My daughter and I were advised to get out of the vehicle for safety reasons, due to smoke. There was no warning lights or any other indication that the Odyssey had a problem. 911 was contacted fire and police responded, it was determined that engine reached max temperature. Odyssey was towed to Honda dealer for diagnostics, it was determined that connecting rod bearing was bad and long block needed to be replaced, starter also imploded and needed to be replaced. I contacted manufacturer to ask for a "goodwill repair" due to NHTSA campaign number 23v751000. Per manufacturer Honda would not offer any assistance for the engine repair even though recall matches exact part affected in the recall. All regular maintenance oil changes, 100,000 mile service, new tires, have been performed on the Odyssey. I can provide receipts and records. The failure mileage was 167,384.

After driving for 2 hrs in single digit temperatures I entered the on ramp to interstate freeway. I lost power, couldn’t accelerate further and the check engine light was flashing. I pulled over on the 4 lane interstate, turned off my car and restarted. Cel went away. This is the 2nd time in 2 winters this has occurred during cold weather. Both on exit/entrance ramps when trying to accelerate after turning with traffic behind me. This can only be reproduced in specific situations and diagnostics are not stored. Honda has a service bulletin on this issue 24-085. I feel it should be covered on all vehicles, regardless of warranty status due to the safety risk.

The idle stop feature sometimes fails to reengage / restart the engine. One time, the van failed to restart and the vehicle completely locked up while I was in an exit ramp to the freeway. I had to turn the van off and turn it back on to get it to shift into drive and go. Similar events have happened a number of times, since the summer of 2025. We have taken it to the dealer twice now, and have been told to "monitor" it. We found the NHTSA report #ea25004 and believe this is the issue we are experiencing. Occasionally, the idle stop will restart, but it's a very violent restart (car sputters and chokes in restart, sounds like it might stall). The car will make a warning light flash and give an error message, but it always clears too quickly to read it.

My 2018 Odyssey has a problem of high pressure fuel pump malfunction. It is come to know that and it can cause stalling the vehicle while running and can cause accident. The same fuel system is shared by 2018 Honda pilot which had a recall. But manufacturer did not issue a recall notice for Odyssey's yet.

While parked on Saturday, 9 different warnings popped up including fuel emission issue and brake issue. Tried to restart the car and failed. Came back later with a jump start kit assuming it was battery related. Car started up fine and drove it on the highway for 30 minutes. The 9 warnings were still present. Continued using the car on Sunday on 30 minute highway drive without issue. Monday morning noticed the warnings were gone. Continued use. Around noon the warnings came back and the car refused to start. Used a jump start kit to get the engine started, but it could only go about 10mph. Attempting to push the accelerator further would stutter the car. Managed to get it to a shop where they diagnosed the fuel pump motor had failed. They told me that the part was listed in a recall. I looked up the NHTSA number - 23v858000. However, my VIN was not included in the recall.

Was have recall my car fuel pump , I put the car in Honda dealership 9am them I back 3 pm watched my dash cam car park in parking lot no one worked on it them just did paper work when I told the manager the story he told me we did it 4 day ago on 11/07/2025 when you have diagnostic if you did it before why you give me another an appointment and broken my day then I back home take the seat out see the fuel pump it’s do dirty look no one work on it then the part number in the paper not the one in the pump.

While on a road trip our vehicle began to run louder, same shifting, same gas mileage but louder especially under acceleration. There was no warning and luckily we made it home only to find out it was the high pressure fuel pump in the engine bay that was failing. We had the previous fuel pump recall completed but now at ~82,000 miles the hpfp goes out, these usually last much longer. Took to an independent shop who diagnosed and fixed problem resolved but said we could have easily been stranded or worse the hose with fuel that was violently pulsating in the engine bay could have come unattached and fuel could leak on the hot engine.

When pressing the accelerator, there is an extremely loud and abnormal noise coming from the fuel pump. The noise is so severe that it raises safety concerns while driving. The issue appears similar to fuel-pump–related problems reported in other recalled Honda vehicles.

My 2019 Honda Odyssey has a check engine light on due to failing fuel injectors. Honda service center told me, the cost to repair would put you out the door @ 1919. 38. My car has fewer than 60,000 miles, for me personally, it's a manufacturing fault. After seeing the check engine light, I didn't drive my car other than take it to the Honda service center.

Honda Odyssey ex-l sport 2025 has been facing the issue of idle stop not working causing engine to stall, engine failing to restart, shutting off completely during mid traffic especially during adaptive cruise control operation. This is causing an unsafe driving situation. While this issue was reported to scott clark Honda multiple times and they have claimed to fix this issue in Aug 2025, the issue continues to exist and root cause hasn't been fixed. This seems to be related towards the on-going investigation by NHTSA. Please help to resolve at the earliest since no further support is being received from Honda.

The Honda high pressure fuel pump recall is an ongoing and critical safety campaign impacting numerous Honda and Acura models primarily from the 2017-2022 model years. The defective fuel pump component can fail unexpectedly, causing sudden loss of engine power while driving, significantly increasing the risk of a crash or fire. I am the manager and CO-owner in an automotive mechanic workshop in miami, and in the last year several Honda Odyssey have arrived at my workshop with this problem with the high-pressure fuel pump. All of these cars were manufactured in 2022 and 2023. Symptoms begin after accumulating more than 80,000 miles traveled. The main symptoms are: problems and delay when starting, loss of power, vibration, noise and tapping of the fuel lines at the inlet of the engine. This vibration and noise are felt much louder from inside the cabin, because the fuel lines are attached to the fire wall of the engine compartment. High fuel consumption, reducing the autonomy of the vehicle up to about 12 to 14 miles per gallon, when the Odyssey has a proven autonomy between 19 and 21 miles per gallon under normal conditions. Strong smell of fuel. The vibration increases by increasing the revolutions per minute of the engine, causing the connections of the fuel lines to suffer deterioration, cracking and loss of pressure, causing fuel leaks that could be the main cause of fire of the engine and the vehicle, in turn putting the life of the driver and his occupants at risk. For a few weeks I wanted to submit this request for extension of recall to Honda for the Odyssey models of the years 2022 and 2023 through the NHTSA. But it was not until today that I decided to do it because I also own a 2022 Honda Odyssey ex-l with more than 90,000 accumulated miles, just 2 weeks ago my vehicle began to present all these symptoms mentioned above.

A mil warning was displayed for emissions system problem flaging our vehicle for emissions testing and registration. The vehicle skips and does not accelerate well from 20-30mph making turns into a busy street unsafe. The computer reads a dtc of p219a. All of this matches the description in Honda service bulletin 21-010 which says it covers 2019 Odyssey of all trim levels. Local Honda dealer (auto nation Honda of chandler in chandler, az) and Honda America both refuse to extend this warenty to our vehicle for repairs. We took it to a third party Honda mechanic for a second opinion and they recommended we follow up on the service bulletin 21-010.

There was a fuel pump failure causing the car to not start properly then shut off. The dealer we took the vehicle to stated that the pump almost exploded.

Tuesday, September 30 at 8:07 pm I was merging onto the interstate after work and my car would not accelerate properly to allow me to merge with the traffic. This happens way more than it should. Since I got this vehicle it has been doing this and scaring my entire family every time. It happens in car line. It happens when I am already driving with traffic on the interstate and when I try to pass a slow car my car will sometimes not accelerate due to the problematic recall issue that these 2018 9 speed Hondas are known for. It puts me in a very scary situation and I dont know what else to do about it.

I have a Honda Odyssey 2016 with low mileage, which I purchased almost 2 years ago. This has happened twice. While driving in traffic, I approached a stop light and applied my brakes. When I applied the brakes, the engine accelerated at the same time propelling the car forward. I pressed on the brakes as hard as I could to keep the car from hitting the car in front of me. The second time this happened, I was able to turn off the ignition and then restart it. This is a very dangerous situation because it is extremely difficult to control the car and keep it from moving ahead. I used all of my strength to push against the brake to keep the car from moving ahead. There are other instances of this identified online if you search for it. There needs to be a recall or a way to fix this problem. I took the car to the Honda dealer on October 8, 2025. He kept it for four days and examined it thoroughly but could not find anything wrong with the car and could not get it to replicate this behavior. I never know when the surging forward might happen.

High pressure fuel pump car had loss of power while on freeway car seemed sluggish prior to going out. The low pressure fuel pump was replaced as part of recall 1/2025.

While traveling in my 2019 Honda Odyssey (40,000 mile) the vehicle completely shut off and placed itself into neutral. The warning lights for emissions system problem, brake problem, and parking assist problem lit up on the dashboard. The vehicle went into neutral and would not allow me to drive at all. Then the vehicle shut off all within 30 seconds. The vehicle would then not restart and now I have to get the vehicle towed to the Honda service department. After looking through other complaints there is a known recall for manufacturer defected fuel injectors for my year model Odyssey but does not appear when I search for recalls. This was an insanely dangerous situation here in oahu where the traffic is very bad. The vehicle gave no warning or check engine light and we have completed every service for the vehicle. The vehicle just randomly completely shut off and would not restart leaving my family of 5 stranded.

Brand new vehicle and system shuts down a few times when in idle mode. . (stoplight, stop sign) then I need to restart the car again.

The vehicle would not accelerate while merging onto interstate and it made a grinding sound. It hesitated for about 5 seconds and was able to finally pick up speed and merge. It is very scary when my vehicle does this.

The throttle can loose power at stop and then suddenly engine picks up the throttle which not normal and this is not maintenance issue as service station and Honda does not confirm the behavior a defect or a problem. This is very concerning.

I bought my van used in March of 2025. Within 6 weeks I noticed when accelerating my van hesitated about 3 seconds before going when I went to take-off. This has caused great concern . Last week it caused me a accident because of the delay in acceleration. Luckily I was not hurt but did cause a accident. I feel they're should be a recall to fix this after reading many complaints about the same issue.

My car went completely dead while stopped in traffic on a busy street. My kids were in the car and thankfully I was able to crank it by pressing the start button. This issue has already been “fixed” and the dealership “cannot replicate”.
