Engine And Engine Cooling Problems of Honda Accord - part 2

I am reporting a serious safety concern involving my 2021 Honda Accord sport se. The issue began at approximately 78,000 miles when multiple warning lights suddenly appeared on the dashboard while driving. At the same time, the vehicle began shaking and had difficulty accelerating. The engine felt unstable and the car struggled to gain speed. I immediately took the vehicle to a mechanic where it was diagnosed with an engine misfire on cylinder 3. The spark plug and ignition coil were replaced. After this repair the vehicle appeared to run normally for a short time, but the exact same symptoms returned shortly afterward. The vehicle again began shaking while driving and experienced loss of power and poor acceleration. This creates a serious safety concern, especially when merging onto highways or driving in traffic where sudden loss of power could lead to an accident. After researching this issue, I discovered numerous complaints from other owners of 2021 Honda Accords describing the same symptoms that ultimately resulted in blown head gasket failures. These complaints appear in the NHTSA database and other consumer forums. The pattern of engine misfires, shaking, and loss of acceleration appears to be consistent across many vehicles with similar mileage. Despite the number of similar complaints, there are currently no recalls associated with my VIN. I believe this may indicate a broader manufacturing defect affecting these vehicles. I am requesting that NHTSA investigate this issue further to determine whether a safety defect exists that could require a recall or other corrective action.

The car can't start because of the recall.

When driving at a normal speed, like 55mph, I’ll still be pushing on the gas pedal and it will drop down to 15mph on its own, then stall. It’s happened several times. I was sitting at a traffic light, went to turn left, pushed on the gas pedal, started to go, then just died. Someone told me they had a car like mine, and it does the same thing, another friend said his 2012 four door Accord just had it happen to his when he was turning left, he pushed on the gas and it started to go, then died, he was hit and it totaled his car. He said it would happen to him all the time, but couldn’t afford a new car. Someone told him that it’s the eco system, that it happens all the time with the Honda Accords. If this is true, Honda needs to recall them, there’s a lot of them still on the roads.

The high-pressure fuel pump on my 2018 Honda Accord failed even though the vehicle had previously been repaired under a recall for the same issue. While driving, multiple warning lights illuminated on the dashboard, including the check engine light and other system warnings. The vehicle began running rough and lost power, creating a dangerous driving condition, especially in traffic. This is the second occurrence of fuel system failure despite the recall repair being completed. The recurrence of this issue raises serious safety concerns, as sudden power loss or engine malfunction while driving increases the risk of an accident. The vehicle is currently not safe to drive due to the risk of stalling or loss of power. The problem appears to be related to the high-pressure fuel pump system that was previously addressed under recall.

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 contact owns a 2019 Honda Accord. The contact stated that while driving approximately 35 mph, there was an alert that the engine was overheating displayed on the instrument cluster. The message to pull over and allow the engine to cool off was displayed. The vehicle was taken to a local dealer, who diagnosed the vehicle and determined that the head gasket had failed and needed to be replaced. The vehicle was repaired. The contact researched online and became aware that the head gasket failure was a known failure. The contact informed the manufacturer of the failure and was referred to the NHTSA hotline for assistance. The failure mileage was approximately 78,000.

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.

Almost all of the 1. 5t engines (l15be) are having head gasket issue where the gasket slowly fails over time resulting in slow coolant loss and at one point sudden overheating causing block and head warping die to design flaw ( groove in between the cylinders resulting in lack of effective and enough surface area for the head gasket to seal the combustion chambers). It has been confirmed by Honda techs and by average 100k to 140k, all engines are failing and the dealers are raking up $ 6k to 9k charge for each change or even having to need new engines half the time. This process of slow leak results in sudden loss of power at highway speeds or acceleration and causing extreme danger of getting hit and having accidents. Took vehicle to mechanic and confirmed coolant leak inside cylinder 4 and 3.

The contact owns a 2018 Honda Accord. The contact stated that while driving 70 mph in the fast lane, the vehicle experienced head gasket failure. The vehicle lost automotive power and decelerated to 5 mph. The contact was able to pull over safely. The engine light was illuminated. The vehicle was taken to the local dealer the next day, where it was diagnosed with a misfire in cylinders #2 and #3, a computer code malfunction, and a blown head gasket. The vehicle was partially repaired. The manufacturer was contacted and assisted with the cost of the repair. The manufacturer confirmed there was no warranty coverage on the vehicle. The failure mileage was approximately 118,000.

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.

Car flashed engine temperature near limit, avoid heavy acceleration and high speed, see dealership warning on dash. Sounds like water moving thru the dash board when driving or turning or right when starting car. Took car in to dealership right away and they confirmed it is a head gasket issue and that they have at least 20 other cars there due to the same issue. My car has now been in the dealership for over a month and a half now and there is not a clear when it will be repaired due to how many other cars they have there with the same issue. I currently have a rental due to having the extended warranty. I want them to buy the car back so I can get another one with out issues. I have two teenagers that are also learning how to drive. All of the maintaince has been done at the Honda dealership.

A 2018 Honda Accord 1. 5t developed an engine misfire, coolant loss, and reduced acceleration shortly after purchase from a dealership on 01/07/2026 (around 156,000 miles / $15,000). On 01/23/2026, during a Honda dealer inspection at about 157,255 miles, the technician noted misfires on startup, found the coolant overflow reservoir empty, pressure-tested the system, and confirmed coolant leaking into cylinders 3 and 4 from the head gasket. The dealer recommended head gasket replacement plus spark plugs, drive belt, and valve adjustment. I was told that continued driving could worsen the condition, leading to overheating and further engine damage. After that diagnosis, the vehicle’s drivability worsened, and it became unsafe to rely on due to misfires and loss of acceleration, especially on the highway. The selling dealership refused to assist, claiming the defect was not present at the time of sale; Honda America acknowledged the head gasket concern but denied a goodwill claim, citing the high cost of the issue and lack of NHTSA enforcement on this issue. An independent repair shop then provided a second inspection/estimate consistent with the same head-gasket repair scope. The vehicle and repair records are available for inspection. No crash or injury occurred, but the defect caused a sudden loss of power and overheating while driving; I was stuck on the highway on two occasions with my hazard lights on after acceleration completely halted. Warning symptoms (the engine light) only appeared when the car suddenly stopped accelerating. Two days after an around-$5,000 headgasket repair, drivability problems and multiple dashboard warnings appeared, including turbo-related concerns; this concern is ongoing.

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.

Blown head gasket.

There are many warming lamps on in the car. My car won't pick up speed it in limp mode once I crank up. I have to turn it off and restart any order for it to go and pick up speed. My number 3 plug keep showing something wrong it has been replaced multiple times but still having the same issue. I had it checked out it's saying the same problem fuel. I have had my fuel pump change and still having problems. 2018 are bad models for Honda and there should be multiple recalls because everyone having the same problems. Head gaskets,fuel injection, turbo problems as well as fuel pump.

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!.

Approximate date (around January 2026), location (e. G. , newburgh, NY area), and circumstances (e. G. , during normal driving). No crash/injury mentioned in my case, but note if it stranded I, required towing, or felt unsafe (e. G. , potential for sudden power loss). While driving, all dashboard warning lights came on suddenly. The vehicle experienced rough running/misfires. Dealer diagnosed low coolant, pressure tested the system, and confirmed coolant intrusion into cylinders 2 and 3 due to head gasket failure. This required full head gasket replacement (parts/labor ~$4,567 total before any goodwill). No external leaks noted initially. Concerned this could cause engine stall/overheat while driving, posing a safety risk. ” dashboard lights, possible misfire codes (if any dtcs like p0302/p0303 were pulled), low coolant without visible leaks. Dealer diagnosis (morehead Honda? from eric koller), repair done/recommended, cost, and that american Honda provided 35% goodwill (shows it’s out-of-warranty but recognized issue) only 91000 miles on the vehicle.

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. Sincerely, [xxx] and [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

I have a Honda Accord sport. My vehicle does not appear on the recall website. I am having so many issues with my vehicle lately. The following lights stay on continuously on my dashboard. The tire pressure light, abs, tired skid traction, brake and steering wheel lights are on. I have tried everything to get these issues resolved and nothing seems to be working. I am thinking now that this could possibly be an electrical issue or sensor issue. I have replaced my batter twice, my passenger side window fell, and I had the motor replaced and it is still not working. My car stalls when I am driving, sitting still and when I turn the air conditioning on. I have had so many repairs done to this vehicle. The invoices will be attached to this as well. I have basically made the care new under the hood, and nothing is working. I need help to get this issue resolved as soon as possible. This is the only vehicle I have to get to and from work daily. Can you please, find it in your heart to help me.
