Other Fuel System Problems of Honda Accord - part 1

I own a 2018 Honda Accord equipped with the 1. 5l turbocharged engine. At approximately 53,666 miles, the vehicle developed a rough idle, engine shaking during startup, intermittent check engine light, and a cylinder 1 misfire code (p0301). I took the vehicle to a Honda dealership for diagnosis. The dealership confirmed coolant intrusion into cylinder #1 after performing a cooling system pressure test and borescope inspection. The dealership determined that the engine has a failed head gasket and provided a repair estimate exceeding $6,000. The dealership advised that the vehicle should not be driven because coolant entering the cylinder can cause further engine damage, loss of power, engine stalling, overheating, or complete engine failure while driving. I believe this is a safety concern because the engine may misfire, lose power, or fail unexpectedly during vehicle operation. A major engine failure at only 53,666 miles is not consistent with normal wear and tear. I am submitting this complaint so that NHTSA can investigate potential defects involving coolant intrusion, head gasket failure, and cylinder misfires in Honda Accord vehicles equipped with the 1. 5l turbocharged engine.

There were no warning lamps or messages prior to the failure. My family was out of town, when the fire occurred. However, the neighbors were home and their home also sustained some damage. My home was a total loss. On June 16, 2026 I received a call while out of town that my home was on fire and it was a total loss. Statements from the neighbors and fire marshal were that the garage was on fire and then spread to the rest of the home. The only thing in the garage that could have started the fire was my hybrid vehicle.

Pulled off my street to go to work, and the car engine started hesitating, misfiring and losing power. I turned around and was able to get it to a safe location, but had to have it towed to the dealership. Dealership ran codes said it was a bad injector issue and quoted me $2,600 to replace all 4. My Accord just turned 9 and has had all recommended services done. This is my 4th Honda and have never had any fuel injector issues with prior cars. My car is not showing as part of the recall for this, but it should be because they are defective. If I had not turned around, a semi could have hit me as I was in an industrial area, because the car all of a sudden lost power. This is an extreme safety issue and should be recalled.

While driving my 2019 Honda Accord hybrid at highway speed, the engine suddenly suffered catastrophic failure. The engine block ruptured, leaving a large visible hole with internal engine components exposed. Oil was expelled into the engine bay and ignited/burned briefly. This occurred without prior warning at highway speed and created a sudden loss-of-propulsion hazard. The vehicle has approximately 48,500 miles and has had regular on-time maintenance via Honda dealership. No warnings or other symptoms were active prior to engine rupture event. Fire dept & nys police arrived on scene prior to being towed. The vehicle is currently preserved at sussex Honda dealer for inspection and awaiting diagnosis.

I was traveling north on highway 55 in huntsville, al when I put the car in sport mode all of the error lights came on immediately. This has happened on several occasions. My passenger seat belt error always comes on. When I call about getting the recall fixed it could never be done because the dealer ships says the parts are not available.

While driving the car it went in to limp mode, restricting the ability to maintain normal driving. It did this because the head gasket needs to replaced because coolant is leaking into # 3 cylinder. My wife and others were put at risk when she had to pull over in an area that was unsafe According to a summerville police officer who came to her aid and helped her get the car to a safe area.

While driving my vehicle suddenly would not accelerate above 20 mph and warning lights all over the dash lit up (check engine, abs brake system, adaptive cruise control, vehicle stability, power steering, hill assist, and brake hold). I took it for a diagnostic, it gave a code for cylinder 3 misfire. I got a tune up the next day along with a fuel system cleaning just to be safe. After about 35 miles of driving I had the same issue 2 days after the tune up, this time no warning lights. I took it back to the shop and this time the spark plug in cylinder 4 was bad. I believe I am at the beginning of what many others have complained about with these same symptoms. This problem makes operation of my vehicle unsafe and uncertain, at any time this issue can kick in and now you are limping along at 20 mph while cars zoom all around you. While trying to get the vehicle to the shop I created traffic buildups and was almost hit multiple times due to the vehicles diminished acceleration.

On may 19, 2026, I was on the highway driving home and without warning my dash lit up with at least 5 warning lights scaring me to death so that I swerved a bit. I stopped on the shoulder and composed myself. I drove slowly home, thankfully I was not far from home. Took the car next morning to the mechanic and was told that the high pressure fuel pump needed replacement. It cost me $1800 which I had no choice because the car was a hazard to drive anywhere. I have recently learned that there was a recall for my 2016 Honda Accord regarding the fuel pump. I never received any notice whatsoever in regards to this potentially serious road hazard otherwise I would have taken my car for service at a Honda dealership. I would like for Honda to reimburse me for this money that I could not afford to replace the failing fuel pump. My car's mileage is only 65k miles give or take. Thank you kindly.

When I would go to accelerate onto the the interstate and would hit around 67-69 mph my car would go lazy and the engine light would come on. This happened about 3 times and then 4th time every single check engine light came on. I took it to the mechanic and he replaced the battery, but said there might still be a fuel issue. I then took it to the dealership and they said I had “bad gas” and wanted to replace the spark plugs, remove the fuel, and do a fuel treatment for 1200 dollars. I was confused on how this could happen and the dealership stated that it only takes one time, so how can I prevent it? they didn’t say and so if I spend the 1200 due to “bad gas” and get “bad gas” again I owe another 1200?.

My car is 2018 Accord 2. 0t the car just started jerking then I brought it to Honda they said head gasket replacement needed, my car was properly maintained and it still happened.

Blown head gasket after multiple spark plug replacements for misfires.

The head gasket failed. Dealer diagnostic was performed and they determined leak of coolant into cylinder number 3. All maintenance done on car. No reason to fail. Further internet search shows that the head gasket failure on the 2018 Accord 1. 5 turbo seems to be a common issue and therefore a manufacturer defect. Yes it is available upon request. When accelerating the car will stall and lose power. Merging on to the highway the car would not move faster than 20mph and could have caused vehicles behind me to hit me. Yes, the problem was identified and reproduced by the dealer. Yes, the vehicle was inspected and serviced but upon receiving vehicle back, problem remained. The only symptoms present was a rough cold start and intermittent rough idle. The check engine light appeared only once the loss of power occurred.

10th gen Honda Accord has a major engine design flaw allowing coolant to pass through the gasket mixing with fuel in the cylinders causing premature head gasket repair which also puts the injectors under immense stress due to high compression. While driving my 2019 Honda Accord to the dealership for inspection. All the lights started flashing on the dash. Highlighting - critical failure detected please stop driving when safe. After a few mins the car’s infotainment system shut off no electrical activity and the car shut off mid drive. Luckily, it was in the morning and not during peak traffic congestion. Had I been going on the expressway I could’ve harmed myself, or someone else. This is highly unacceptable that a car with only 96k miles has a serious engine issue like this. I have maintained the oil changes at the required intervals, changed the fuel pump under recall, tires, brakes etc. After towing to the dealership. Diagnostics were performed and it was confirmed that the coolant was empty and radiator low. Which then prompted the dealer to perform a borescope test for the cylinders and it was found that cylinder 3 had a misfire and was leaking coolant into the cylinders causing premature wear on the gasket as well. The car is out of warranty and the service advisor said to me that they had another Honda just like mine with the same issue. This isn’t an isolated incident and many owners with the 10th gens have the same exact issue nationwide and Honda turns a blind eye and expects us to pay over 6,000 for the repair it’s a total scam! they are making money hand over fist without any recall and just scamming their customers. This is truly unacceptable and should be investigated immediately and Honda reprimanded!.

The engine stalled on the freeway. Has been having rough idles on cold start. Water gurgling/sloshing sounds coming from behind the dash on cold start. White, sweet smelling smoke periodically comes from the exhaust. Followed up with spark plug replacements. The vehicle still has all previous issues. Upon further inspection coolant reservoir is empty indicated a leak. No leaking fluid has been found. Suggests internal leaking. Issue is likely failing head gasket issue. Bissel v. American Honda CO. Has been suing over this issue. The head gasket is allowing coolant into the cylinders mixing with fuel causing misfires and stalling the engine. Extremely dangerous. Likely to cause accidents.

My car is having issues with the head gasket. My car check engine lights came on like a lit christmas tree with many warnings (emission system, brake system, departure, uphill and many other more). I took my car into capital Honda for a diagnostic on 5/4/26 and they informed that it was the head gasket that needs to be replaced. They are charging me $6000 to repair and do not have the funds to fix. Also I contacted Honda corporate since I read on google that I may qualify for the goodwill program and they said I didn’t qualify since I did not purchase warranty on the vehicle when I got it. I also do see that there is a lawsuit in place for this. I’ve kept up with my car maintenance and never had an issue till now. The car is running rough and it’s shaking a lot. It’s also loosing coolant from the reservoir.

Upon recent repairs completed by an official Honda licensed dealership for the fuel pump due to the related issue of stalling, misfiring, insufficient fuel economy and safety concern. My vehicle has continued to stall, misfire or idle extremely rough. Upon local investigation the error code p0203 and p0303 have populated as the most recent issue. No longer allowing me to drive the vehicle as it remains in limp mode. Previously error codes such as p0304 and p0302 as well as the associated error codes for the injector circuits indicating “open” have previously been detected intermittently and now permanently. In previous events within the last 3 months I have been stranded on highways due to the same stalling, misfiring and limp mode issue after I have previously been inspected by a Honda dealership and promised the issues would resolve. Unfortunately driving at respectable highway speeds and even local city limits my safety as well as my child and spouse’ safety have been put at risk due to the sudden deceleration caused by consistent misfires or limp mode effect which can cause me to have a collision with no warning. I have nearly been in 3 accidents due to this persistent issue.

Car keeps throwing cylinder 2 misfire, replaced all spark plugs, fuel indicators and still having issues. Think it’s the ecm/pcm is bad or there’s a bad connection.

Car suddenly stopped accelerating and became very unsafe and unable to be driven. Car has approx 100,000 miles but just was inspected (3/2026) and has been well maintained. It has been serviced at Honda service centers (Honda city and advantage Honda) as well as my private mechanic. Private mechanic diagnosed the issue as faulty fuel injector citing code: p 303. I completed the fuel pump recalled repair at advantage Honda dealership on March 22, 2023.

Car went into limp mode.

When driving the car the first time this happened on April 19, 2026 I excellerated after stop light to cross a highway. That is when the car started sputtering and the check engine light started flashing it would only go 5 miles per hour, I then pulled to the side of the highway turned the car off restarted the car check engine light was then turned off I excelerated. The check engine light started flashing again, the car would not proceed again. The second time this happened was April 21, 2026, we had not had the problem happen for a couple days so I drove it again got to the stop light and excellerated again and the same problem happened. We are now not driving the vehicle. I looked up to see if there was a recall on the 2019 Honda Accord my VIN number did not come up. However the statement your organization has put out is “nearly” all 2019 Honda Accords have been affected by this recall. This is the only car we have and we cannot get it fixed. Please help me.

While driving at highway speeds, the vehicle experienced a sudden jerking and a catastrophic loss of motive power (limp mode). Simultaneously, multiple safety systems failed, including the collision mitigation braking system (cmbs), adaptive cruise control, and road departure mitigation. The vehicle became a road hazard in active traffic. A certified Honda dealership technician inspected the vehicle and confirmed a premature head gasket failure with coolant intrusion into cylinders 2 and 3. The engine is non-drivable and the vehicle is at 84,000 miles. Despite the documented nature of this design defect and its current litigation, american Honda motor CO. Has denied any assistance. The vehicle also has an open safety recall (24-009) for a fuel pump failure which presents identical safety symptoms.

I was driving down the highway, and the dash started to flash a message about the vehicle being unsafe to drive, stop driving immediately, call dealer. I was able to stop and then turn left across traffic with limited power; and continued to make my way back to work thinking I could probably get to my parking lot. The dash continued to display warning lights, starting with brake failure, then parking brake failure, and then the whole series of possible failures. I continued to drive about one mile. I shut the power off an powered up twice thinking that might reset the sensors; but they continued to fail. As I continued to drive there was limited power to the throttle, and I eventually coasted through a red light and into my work parking lot where the vehicle shut down entirely, and eventually fully locked up (couldn't start or event put in neutral to push). I had the vehicle towed to back to the dealer, and they diagnosed the problem as a failed transmission cooler. Of note, I had purchased the vehicle brand new less than 3 weeks before this incident and the vehicle had less than 600 total miles on it. There were no prior signs of trouble or warning lights.

I am reporting a recurring safety concern involving sudden loss of power and engine stalling while driving. The vehicle wouldn't accelerate during normal driving condition and lost power. After the vehicle stalled, all the warning light came on. My husband retired to restarted the engine but the it made cranking noise. After couple of minutes it barely restarted and was able to drive about a mile and then it stalled again. Repeated 4 times to finally make it home. The vehicle has a prior recall history related to the fuel system. The current symptoms are similar to fuel delivery or fuel system-related failure conditions. I called Honda corporate to provide flat bed for the towing but they refused. My husband cleared the code (p0087)so the vehicle was free of warning lights so he can drive to the dealer next morning. We brought the vehicle to Honda dealership for diagnosis. However, the issue could not be reproduced during an inspection due to code (p0087) was cleared and couldn't reproduce the code which directly indicates fuel rail pressure low. Given the safety nature of this condition and the fact that it occurs while driving, I and requesting an investigation into whether this may be related to a known defect of incomplete resolution of prior recall -related repairs. This issue poses a potential safety risk due to unexpected loss of engine power during operation. The dealer of joyce Honda has test driven and couldn't find the fault so they want me to pick up the car at my own expense and safety risk.

Pulling out in front of high speed traffic, engine went into safe mode with check engine light. Fortunately a car at high speed avoided rear ending my car. Upon evaluation, dtc code p0303 (cylinder 3 - misfire) was present. Coils and spark plugs were changed but car was still misfiring. Honda has a warranty for 150k/ 10 year on fuel injectors but this VIN was not on list based on Honda service department. The Honda service department evaluated and car has head gasket leak in cylinder 3. This is a widely known problem reported on many Honda owner websites and Honda service acknowledged it was an issue but is not a “recall” despite the potential safety risk on the road when car goes in to protect / shutdown mode. The nature of this issue occurring on a well maintained car with 147k miles that is 8 years old and not being a recall and a safety related item is being reported by me as me and my family could have been impacted by a rear end collision as car shut down / protect mode. This could and likely has occurred to other owners and possibly attributed to accidents and safety of passengers. Honda wants over $11k to repair the car which includes fuel injectors / plugs / coils / new head as they reflect old head can’t be used even if machined / head gasket. This issue is a safety related issue and should be a Honda recall as the head bolts are a known design issue causing premature failure of the head gasket. Submitting this to document my incident, protect the public driving this model and year and hopefully providing information to warrant a recall so that all repairs will be performed under recall warranty. Also to protect the public from a Honda Accord safety issue for 2018 Honda Accord lx.

In 2018 Honda Accord with the 1. 5-liter, four-cylinder turbo engine that had a head gasket fail at 110k miles which has been diagnosed and confirmed by local Honda dealer with misfire codes/counts on cylinder 1 due to coolant leaking inside cylinder 1 and 2 due to this bad head gasket. Due to the bad head gasket and coolant leaking into cylinders, this caused the fuel injectors to clog and fail. Creating rough idling and poor engine performance, which could cause car to stall at any point, creating a safety concern for those in the car if stalled/stuck on public roads. Additional discovery information found here of Honda America acknowledging the defect and encouraging dealerships to report this issue with incentives.

I was driving down a 45mph street when my car shut down, complete power failure. Dashboard lit up with all kinds of warnings. It had to be towed to the nearest shop.

I just submitted a complaint but wanted to add that after my car lost all power on a 45mph road and went into limp mode it then was towed to the closest shop. I do have a warranty but when I called Honda they said it wasn't covered the shop I took it to charged me 4100 dollars for a blown head gasket which from researching it looks like this is happening to all 2018 Honda Accords this is low mileage and unacceptable , turns out after I called and told Honda they refused to pay because I had already had the shop look for the problem so I had to pay 4100 for an issue Honda clearly knows about this is unfair and Honda needs to fix this issue.

I was driving down the road and when I tried to hit the throttle to speed up a little suddenly the car just started misfiring randomly with zero warning beforehand. I tried to hit the throttle a couple more times but it kept misfiring and then the engine light, tpms light, traction control light and a couple other lights all lit up and I immediately had to pull over to the side of the road because it was extremely dangerous. I will also add that I had just got off the freeway maybe two minutes prior and it would've been a completely different story if that had happen then. I have an obd scanner in my car and I immediately pulled it out to check what the codes were which it was a single code all around p0087. The high pressure fuel pump had completely died in the middle of me driving and was not even allowing a test when I took it in for a diagnostic. I replaced the high pressure fuel pump and it completely resolved the car issues and the codes went away immediately. I still have the faulty pump in my possession to. Be inspected by someone if needed. The only reason a crash or something extremely tragic didn't happen is because it was later at night and the cars behind me happen to be a decent enough distance for me to be able to get over to put my car in a safer position to not obstruct the road and get a tow truck to assist me.

I had a misfire on cylinder three. All vehicle lights came on. Vehicle had spark plugs and fuel injectors replaced. The problem persisted and the next code I received was a turbo burst under pressure code. So turbo and water pump were replaced. This made the problem worse because the new turbo made the head gasket leak. Now after paying $4000 in repairs I have to have the head gasket replaced for another $3000. This is a serious problem with these cars. Wish I never bought this piece of trash. I also replaced all break rotors pads and hoses. Terrible vehicle. Do not buy.

I was driving down the highway going 70 mph on my way home from work and my cars engine shut down and I pulled to the side of the road as safe as I could. Went into limp mode and I was not able to drive it home. Gave a check engine light. I had to pull the car home with a truck. I bought an obd code reader and it was giving the code poo87. Doing research this code is for low pressure at the fuel rail. I found that this is a common problem for this car. Specifically the high and low pressure fuel pumps which currently have recalls. When searching with my VIN # it does not pull anything up. This could have been disastrous.

I started driving this vehicle and all of a sudden it started slowing down, and would not go up to speed. I had it fixed, the car started skipping, making a jerking movement while driving. I made an appointment with tameron Honda of birmingham on 3/26/26. As soon as I pulled up to Honda dealership the engine light was on. The company was trying to bill me 6100 dollars for fixing the car. I do not have that amount on hand and I need my car. I had to drive my car away from the dealership while it was in idle mode state into traffic the car moved so slowly that I could have wrecked. The dealership did not do their due diligence by going off of the VIN number and making sure that the customer is safe with their brand. I was told that they did a full inspection at the dealership. I have been scared to drive this vehicle since the issue keeps happening.

The engine stop/start system on my 2016 Honda Accord, VIN [xxx], has stalled and shut off without warning in active los angeles traffic dozens of times since September 2025. The vehicle loses all power mid-drive with no warning — no dashboard lights, no warning sounds — leaving me unable to accelerate or respond to surrounding traffic. The condition has progressively worsened and now includes repeated no-start failures requiring three documented tows. The component failing is the engine stop/start system. The vehicle is available for inspection upon request. My safety and the safety of others hav been put at risk repeatedly. I am a [xxx]. My wife, age [xxx], has [xxx] and has been a passenger during stalling events. Sudden unexpected stalling in active los angeles traffic creates immediate foreseeable risk of rear-end collision and loss of vehicle control. This risk has been experienced dozens of times over six and a half months. The problem has been presented to Honda of hollywood, a certified Honda dealer at 6511 santa monica blvd, los angeles CA 90038, across five separate visits. Each time the dealer concluded no problem could be found. On one visit I was charged nearly $2,000 for spark plugs and a gasket — work with zero diagnostic connection to the stalling complaint. The vehicle was returned to me in an unsafe condition after every visit. On [xxx] the tow truck driver who responded to my third documented tow independently experienced the failure, could not start the vehicle, witnessed the complete failure sequence, and declared the vehicle unsafe to drive. He is an independent third-party witness with no stake in this case. I have video documentation of the vehicle stalling in active traffic on multiple occasions. I have voicemails from Honda of hollywood's own service advisor documenting their diagnostic failures. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On June 13, 2025, the fuel pump was replaced due to a recall. After the fuel pump was replaced and, in particular, after reading the Honda forums for this car, all the warning lights in the instrument cluster came on. After my mechanic checked my car and, with his knowledge of this type of vehicle, he recommended replacing the fuel injectors at 86,000 miles. Honda recommends replacing the fuel injectors at 1000 k. In the forums, this is what owners of the 2018 Honda Accord are doing.

I am reporting a failed remedy for recall 24-009 (23v-858). Following the fuel pump recall, my 2018 Accord stalled in traffic on March 21. On March 24 upon starting my vehicle all warning lights were illuminated on the dashboard, millennium Honda admitted the o-ring was misinstalled. This error triggered codes p0172/p0176 less than twenty-four hours later. The dealer is forcing me to pay $425 for damage caused by their botched recall repair.
