Engine And Engine Cooling Problems of Honda Accord - part 1

This vehicle is on its 3rd set of injectors within a year. It is a known problem that Honda knows they keep replacing them but they keep going out causing a misfire.

The cylinder head gasket on this vehicle has failed, causing engine coolant to leak into the combustion chambers (coolant intrusion). This has resulted in a recurring and dangerous loss of motive power that has put my safety and the safety of other motorists at risk on multiple occasions. Specifically, the vehicle has repeatedly entered "limp mode" while in active traffic, causing a sudden, drastic loss of acceleration that left me unable to maintain the flow of traffic or safely maneuver. This component failure is available for inspection upon request. The problem has been officially confirmed by holman Honda of fort lauderdale, where technicians diagnosed the blown head gasket and confirmed the presence of coolant in the cylinders. The manufacturer's authorized dealership has inspected the vehicle and provided a formal repair estimate. Prior to the multiple "limp mode" failures, the vehicle exhibited clear warning symptoms starting in late 2025, including violent engine stuttering and a "shimmering" vibration during cold starts. Additionally, a distinct "gurgling" or bubbling sound was audible behind the dashboard, indicating combustion gases displacing coolant. During the actual failure events, the dashboard displayed a "christmas tree" effect of warning lamps, including "emissions system problem," "brake system," and "power steering system" alerts, which disabled critical safety and driver-assist features while the vehicle was in motion. This persistent design defect has created a high risk for rear-end collisions and total engine seizure.

Over the past several years, there have been multiple instances where I or my wife are driving on the highway and the engine light comes on or starts flashing, and I am unable to go faster than 50 miles an hour, and the engine itself feels to be underpowered. We have taken it to the dealership for repair at least five times over the past five years and in each case they have attempted to do a repair and said the issue has been resolved, but the issue continue. At at least one of those visits, they have diagnosed the issue as an engine misfire issue. The issue has intensified from the initial symptoms, (which were as I described, but resolved by turning the car off, waiting 30 seconds to a minute and then turning the car on again) to how it is now: in addition to the check engine light, every other light and warning system has gone off when driving on the highway and the engine was unable to go faster than 40 miles an hour, and it does not resolve by restarting the car. The dealership and Honda America’s main phone line have as of yet been unable to give me a clear answer as to why this is happening or whether it can be fixed. A sudden drop in speed and power on the highway as we have experienced many times over the last five years is inherently extremely dangerous.

Yesterday, January 30, 2026 as I was driving (approximately 30mph) my car seized, came to a stop, dashboard lit up with multitude of words/symbols. After approximately 15 seconds I was able to use the gas pedal and the car drove. My safety was at risk, this sudden stop jolted me hard. If there was another vehicle behind me I would have been hit. The warning messages were so quick and cleared away with seconds that I cannot recall. I drove to my local dealer and the battery cables were checked and ok. I scheduled an appt for Monday Feb. 2nd as this was Friday. On January 21st this local dealer replaced my battery, after months of "computer glitches" that were never resolved with two dealers and 4 dead batteries.

I was taking my wife’s 2019 Honda Accord into a dealership for a factory recall with a fuel pump issue. After I dropped it off, I got a phone call, letting me know that they had some bad news and that the cars third cylinder had failed due to a blown head gasket and coolant leaking into the cylinder. There has never been a check, engine, light or code or sign of any kind of issue with this vehicle up to this point I have it regularly serviced at Honda dealerships after doing some research. This seems to be a recurring issue with people in this make and model of Honda Accord with the 1. 5 t engine. I would like to have someone contact me regarding the expense related to this repair as I believe it should not be on the owner to cover such cost when it is a recurring and known issue with this vehicle.

Head gasket blew randomly. Just hit 100,000 miles. I was on the highway and my speed just started to decrease 65 to 35.

I purchased this 2018 Honda Accord sport brand new from the dealership, relying on Honda’s longstanding reputation for reliability and longevity. At approximately 120,000 miles, the vehicle suffered a blown head gasket during normal driving conditions. The vehicle has been properly maintained According to Honda’s recommended schedule. I have already opened a claim with Honda corporate regarding this issue and am currently awaiting their response. Despite proper maintenance, this catastrophic engine failure occurred, suggesting a design or manufacturing defect rather than misuse. This issue presents both a safety concern and a substantial financial burden, as I am a single mother of four who depends on this vehicle for daily transportation. Based on reports from other owners, this appears to be a widespread defect affecting 10th-generation Honda Accords with the 1. 5l turbo engine, which I respectfully request NHTSA investigate.

Head gasket failure. Dealership did inspect vehicle and said this is a common issue. No warning prior to headgasket issue.

Headgasket seems to be forming a leak. Checked coolant today, zero leaks on coolant system but coolant was extremely low. It is sad to see that Honda has become so unreliable.

Starter grind and not starting.

My car shut off on the road. I tried to accelerate but all my lights on the dashboard came on. I wasn’t able to accelerate more than 20mph. I was about to make it back home. Today I tried to take it out on a test drive, it’s drivable but I was not able to accelerate. Every time I pressed the gas, my car would stall. This is the 4th time it happened.

My vehicle started having issues with misfires approximately 2 years after I bought it in January 2020. I bought it new from the dealership in salinas California. I took it to morgan hill Honda for repairs. It’s had 2 misfires and I took it in for a fuel pump recall. About 2 weeks later all my lights in my dash come on. I took it in to get looked at and they said it’s the turbo engine, $3k to fix it. I’ve had nothing but problems and it’s like a bandaid of a fix every time. The first time it happened I was merging onto highway [xxx] and it gave out and slowed down to 25mph. I had to pull over to the shoulder almost caused an accident.

Financed a used 2021 Honda Accord sport in April of 2024 with 68,671 miles. About a month ago, with no warning signs of any sort such as overheating etc. . . My car did not want to start, finally started but was sputtering with a rough idle, my dash lit up with like 7 or more warning lights. Including a flashing check engine light. All the were safety warnings from braking system not working, to power steering to emissions failure, etc. . . And to take to dealership. Got the car to a local mechanic to get a diagnostics reading and was told I had a misfire in cylinder 2. Replaced the #2 coil and spark plug. Thought everything was fine until picking up my daughter from school and then all those warning messages lit my dash up again including the flashing check engine light. Car started sputtering and went into limp mode. Lost power and by the grace of god was able t9 coast off the major blvd away from traffic and out of harms way. Very, very scary. My life literally flashed before my eyes. Not only my life was in danger but my daughters along with other drivers around me. So I took it back to mechanic and he ran diagnostics again still had a misfire. He could not pin point the exact problem. Took it to the dealership and they confirm it was a faulty head gasket between cyl 2 and water jacket. And they quoted me a price of $5,998. Which I can not afford. And feel im not responsible for catastrophic major mechanical failure. I maintenance my car regularly thru the dealership so they have record of me properly maintenancing the car. Head gasket failure at 80,000 miles is absolutely unheard of. Until I started researching and come to find out this is a design flaw made by Honda. I was flabbergasted with the amount of people with the exact type of problem. Im afraid that even after repairing this problem that it may happen again down the line. And that would be putting my life in danger. Vehicle is still at dealership being that I can not afford the repairs.

Stretch timing chain 1. 5 t, 86000 miles. It is very common in these motors. Just had to pay $2400 to have it replaced.

The first time was at 93,000 miles where my car started to surge and went into limp mode but once I shut the car off and turned it back on everything went away and the car was fine. It did happen a couple more times, but as soon as I would shut the car off and turn it back on the code was cleared and by the time I got it to a mechanic there was no known code. This last time was at 220,000 miles I was just entering the freeway and once on the freeway, my car started to power surge really bad jolting me back-and-forth back-and-forth. This did not let me continue to finish reaching my highway rate of speed with cars coming up fast behind me nearly hitting me. Car continued to surge, and then went into limp mode and I had to pull over on the side of the freeway. I brought my car into Honda of san bruno, California. They informed me after inspection that I had a cylinder three misfire due to a bad head gasket. They are receiving 3 to 4 of these a day and is a huge problem. I later found out that there’s a class action lawsuit for this head gasket failure that put me in danger and now has my car sitting in front of my house unable to drive.

Was told I have a blown head gasket on cylinder 3 with 90k miles on my vehicle. No check engine light has been on.

Blown head gasket at around 91,500 miles even though car have been kept up with oil change around 5,000k mile. It is currently in the mechanic shop as of 1/12/2025 awaiting repairs (parts are being order as we speak). So, probably can't have it inspected if requested unless it is soon. The random/early head gasket getting blown with not such high miles would have been devasting if I was driving on the highway. Since, it would cause the engine to over heat as the coolant is leaking into the engine piston and some case could cause lost of power on the highway. This problem seem to be quite common or expected as talking to the dealer and they were aware that a portion of these 1. 5l turbo engine head gasket are getting blown. The vehicle or component has been inspected by an independent service center. I got misfire detected on cylinder 3 on 12/17/2025. I replace the sparks plug and it ran fine till 1/10/2026 when all of a sudden I can see the temperature gauge climbing. I stop driving the car that day on 1/10/2026. I check the coolant overflow reservoir on 1/11/2026 and found it strange that it was almost empty. I decide to take it to the mechanic on 1/12/2026 because I didn't see leaks anywhere and that was when they found the head gasket has failed and was slowly dripping coolant into the cylinder.

The vehicle experienced a catastrophic engine malfunction resulting in a no-start condition. The vehicle is currently inoperable and is available for inspection upon request. The engine failure caused the vehicle to lose power and become unreliable, creating a risk of breakdown while driving, which could have resulted in being stranded in traffic or an unsafe location and posed a risk to my personal safety and the safety of others. Yes. An independent repair facility confirmed the vehicle would not start and diagnosed the engine as failed. The vehicle was subsequently towed to another facility, where the condition was again documented. The vehicle has been inspected by independent repair facilities. The extended warranty company, route 66, reviewed the claim and denied coverage based on their assessment. No inspection by the manufacturer or law enforcement has occurred. Prior to the failure, the vehicle exhibited warning indicators and operational issues, including overheating symptoms. These issues worsened over time and ultimately resulted in complete engine failure and a no-start condition.

All dashboard lights are on & will not go away!.

I'm having symptoms of cold startup engine rattle type clatter sound for approximately 2-3 seconds and then it goes away. Doesn't do that again unless the car sits for a period of time. If it's been started recently like within 1 hour or 2 hours it will startup with out making that metal rattle/clatter sound for 2-3 seconds. I was told it's likely the 2. 4l engine vtc actuator is failing letting the engine oil drain out causing a dry start. I was told it was a common issue and even the internet is saying the same thing that this is a widely known issue. There should be a recall for this because this should not be happening my car has only 156,000 miles on it. And I've own cars with well over 200,000 miles and that's never happened never had I had an engine problem related to the timing chain or the vvt system. I'm hoping this is a recall where will be soon because it's not affordable repair bill for many people. Please let this become a recall or whatever it's called to have the manufacturer take responsibility and fix the problem. I would have not had bought this vehicle if I was aware of this issue probably because it's not a low cost repair I was told. Otherwise this car is a great car runs good drives good once it starts and runs for a few seconds. It's only when the car sets for a period of time not running and you go just start it and you hear that rattle for 2-3 seconds. When I bought the vehicle it wasn't doing this at least not when I first bought it.

My wife was driving on a highway while taking our grandchildren to day care. The vehicle lost power causing her try ti pull to the side of a main highway. All of the check engine lights went on. We brought the vehicle to Honda and the dealership said they found coolant in the combustion chamber. It needs a head gasket, at a cost of $4800. 00. The car has 76,000 miles on it. We understand that there is currently a class action lawsuit for Honda Accords of this year and make. Kindly advise us as to what we can do as this is causing us extreme stress and financial hardship. We need help. Thank you for your assistance.

Engine began to have an odd stutter and trouble accelerating which was initially believed to be spark plugs after a full tune up did not fix the issue took to my local mechanic. Diagnosed the issue as bad fuel injectors likely due to the fuel pump recall. Code popped up as cylinder misfire initially which didn't make much sense considering a full tune up was completed less than a month prior. After further diagnosis issue was found to be a blown head gasket causing several thousand dollars in repair due to having to completely disassemble and reassemble the engine.

The engine cylinder head developed a crack causing coolant leak, causing the coolant system to lose fluid. The leak originated from a hairline crack in the cylinder head, which has been confirmed by an independent, certified mechanic. The vehicle remained drivable initially, but a loss of coolant could lead to engine overheating, and catch on fire or smoke creating a potential safety hazard for the driver and others on the road. The vehicle was inspected at an authorized dealership at the direction of the manufacturer, which performed a teardown to diagnose the issue. After this inspection, additional engine components (timing chain and head gasket) were identified as damaged, though these failures were not present prior to the teardown. Other users facing similar leak issues were treated the same by dealership blaming other component issue and disregarding the visible crack. This defect appears to affect multiple vehicles of the same engine, as reported by other owners nationwide. Warning signs included coolant loss, which could escalate into a larger safety risk if not addressed. I have attached few user complains but if needed I can provide lot more user complaints around the nation as it is never ending.

Fuel pump is bad causing the car not to start.

The contact owns a 2015 Honda Accord. The contact’s son stated that while driving at an undisclosed speed, the vehicle stalled and failed to exceed 50 mph. The check engine warning light was illuminated. The vehicle was able to restart; however, the failure persisted. The vehicle was taken to the dealer, where it was diagnosed and determined that there was a misfire in cylinder #2, causing engine failure, and the contact was informed that the engine needed to be replaced. The vehicle was not repaired. The vehicle was then taken to an independent mechanic, where it was diagnosed that the fuel pump had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 164,040.

Honda Accords have a 1. 5 l engine, which all have an issue with the head gaskets either overheating or mixing coolant into the cylinders. They’re all doing it eventually because there is a design flaw Honda doesn’t want to honor it and the car will just stop on you on the freeway because coolant touches the spark plugs. Honda is denying the issue when there’s a whole facebook page and internet, page of people saying the same thing they’re quoting and unreasonable amount to fix it almost the cost of the car. It is a very dangerous safety issue and eventually someone could die and needs to make a recall immediately before that happens. Most shops don’t even want to touch the car because it’s a safety issue. If we can get this past ASAP for anybody who has that car or anybody that’s gonna buy that car the safety for them in their family.

My 2018 Honda experienced a catastrophic engine failure (blown head gasket) at only 30,012 miles. A head gasket is not a wear item and should not fail at such low mileage. I previously reported related symptoms during dealer service visits in July 2024 and August 2025, including signs consistent with cooling or engine performance issues, prior to the complete failure. The vehicle has been properly maintained, has not been abused or modified, and shows no signs of neglect. Honda has denied goodwill assistance solely due to vehicle age, despite the extremely low mileage and premature nature of the failure. This appears to be a durability defect resulting in premature engine failure well below expected service life.

Full pump engine.

Loss of power engine malfunction on 2022 Honda Accord sport 1. 5 t experiencing repeated misfire codes, fuel injector failure, and suspected head gasket coolant intrusion. Vehicle has never overheated and maintenance has been performed as required. A second Honda service center advised, they have repaired multiple Accord sport 1. 5 vehicles with the same failure pattern. Honda corporate opened case #16059306 but multiple voicemails to assigned case contact have gone unanswered. Concerned about safety due to potential engine failure or loss of power while driving.

I would like to report a known issue with the Honda Accord sport 1. 5t. My head gasket went out Aug. 2024 with about 100,000 miles on the dashboard. The cost to change it was about $4100. My turbo charger is now out Dec. 2025, and they are quoting me about $2100 before taxes. The dealership did advise that there is a known issue with the head gasket going out prematurely due to a default with the engine. They also advised that the turbo charger normally goes out after the head gasket is replaced. Please work on having the engine recalled. This is awful. After researching this issue, I see thousands of others are having the same issue. Best regards, yvette j.

My car has a hole in the motor, the throw rod shot out of it. The dealership classic Honda refused to do any real investigation and is relying solely on the dipstick reading. This clearly violates me in plenty of ways this is what I sent them. I am formally escalating this matter and requesting immediate supervisory review and intervention regarding the inspection and handling of my 2023 Honda Accord hybrid. The dealership is relying solely on a dipstick reading taken from an engine with a breached engine block. Once the engine block is compromised, the crankcase is no longer sealed, and oil redistributes into different internal cavities and passages. Under these conditions, a dipstick reading is not a reliable or valid method to determine pre-failure oil quantity or causation. I specifically requested that the oil pan drain plug be removed so the oil could be measured directly, which would provide an accurate and objective assessment of oil quantity. This request was refused. I was told, verbatim, that the dealership would not touch the vehicle any further. This refusal to perform a basic, non-destructive verification step, while continuing to rely on an unreliable post-failure dipstick reading, is not consistent with proper diagnostic procedure or good-faith warranty investigation. At this point, I am requesting: immediate supervisory review of this case assignment of a qualified Honda representative or supervisor to oversee a proper inspection documentation explaining why a direct oil measurement was refused confirmation that the vehicle and all components remain preserved for further review I am not asking for speculation or opinion. I am requesting a proper, objective, and technically sound investigation. Please treat this as a formal escalation request. I am prepared to pursue arbitration and further remedies if this matter continues to be handled without appropriate diagnostic standards. I request a response within 48 hours. Sincerely, [xxx] information redacted pursuant to the freedom of.

When I was accelerating the vehicle on 12/21/2025, a flashing check engine light came on, and the car started driving very roughly immediately, with an intense vibration. I noticed a lack of engine power, but the hybrid motor and battery kept me going for roughly 1 mile until they were depleted, after which I was unable to accelerate the vehicle. At that time, the car continued to decelerate, no matter how much I depressed the accelerator. I was able to safely pull over and turn the car off. I let it sit for one minute before turning it on again, at which point it behaved normally. I drove very cautiously to my destination, making sure to accelerate very gradually. This sudden lack of power put myself and others on the road at risk, as it was very sudden with no prior symptoms/warning lights, and I had no recourse besides pulling over as soon as possible. Over the next few days, I researched the problem online, and owners of Honda Accords from that generation (10th generation, model years 2018-2022) reported head gasket failure on all engines Honda offered the 10th generation Accord, including the 1. 5 turbo, 2. 0 turbo, and 2. 0 hybrid engines. This problem is also reported on a slew of other Honda vehicles from roughly that time period. I brought it to motor werks Honda in barrington, IL on 12/24/2025. After they completed their analysis, they determined it was a failed headgasket.

Car started overheating randomly while driving and pulled over to see why. Opened the hood to white smoke everywhere and an active leak of coolant by the exhaust manifold. Took it to a mechanic and was told the cylinder head itself has porosity and/or a hairline crack. Pressure tested as well and can visibly see the leak coming from the cylinder head itself.

The vehicle, a 2019 Honda Accord, experienced a catastrophic engine failure (blown head gasket) and entered "limp mode" after being operated for approximately 18 months with an unaddressed, high-priority federal safety recall (NHTSA 23v-858). The vehicle currently displays dtcs p0100, p0113, and p023d, which indicate severe air/fuel metering and boost pressure correlation failures. Primary cause: consequential thermal stress the primary cause is likely thermal degradation of the head gasket resulting from a prolonged "lean-burn" condition. Recall defect: the recalled fuel pump impeller is known to deform, restricting fuel flow. Lean condition: a restricted fuel supply causes the engine to run "lean" (too much air, not enough fuel). Lean combustion is significantly hotter than normal combustion. Heat accumulation: over 1. 5 years of operation with this restricted flow, the engine experienced repeated, excessive thermal cycles that compromised the structural integrity of the head gasket. Limp mode trigger: the stored codes (p0100/p0113) show the ecu was struggling to compensate for the erratic fuel/air environment created by the failing pump. Secondary assessment (the dealer's claim): the service advisor (paul) has alleged that aftermarket components and a missing turbo gasket caused the failure. Assessment: while aftermarket parts increase scrutiny, a missing external turbo gasket typically causes an exhaust leak or loss of boost, not an internal head gasket failure. Contradiction: the dealer must provide empirical proof that these parts caused the failure, whereas the NHTSA recall is a pre-documented, manufacturer-admitted defect known to cause the exact stalling and "limp mode" symptoms the vehicle is currently exhibiting. Conclusion: the most probable cause is manufacturer negligence. By failing to provide a remedy part for 18 months, the manufacturer forced the vehicle to operate under a documented defect that creates the exact high-heat conditions required to cau.
